Monthly progress report

2026-03-09T00:00:00+00:00

This month, we talk about a large performance regression, the new dashboard UI and Flycam, and the weekly "Overte Warmup" event.

Performance regression fixed

We fixed a large performance regression introduced in version 2025.09.1. 74hc595 noticed awful performance on their workstation with old dual Xeon E5-2690v2 CPUs getting only 30 FPS with their Nvidia RTX3090 in the tutorial world. Even with such old CPUs, performance should be much better than that. Looking into it myself, I also saw a ~50% decrease in engine (physics) performance on my machine. In my case, 50% higher frame times still meant hitting the 90 FPS frame cap in VR and the 60 FPS frame cap in desktop mode, which is why I never noticed the issue myself.

Our changelog for version 2025.09.1 didn't show anything suspicious, so I set out to use a process called "bisecting" to find out which change introduced the performance regression. I ran git bisect telling it the last known good commit and the earliest known bad commit. Git then checks out commits in the middle for me to manually build, test, and tell Git if it suffers from the issue or not.

After just two hours I found the culprit: The virtual keyboard used in VR was parented to the avatar. It turns out that having the virtual keyboard follow you around is extremely computationally expensive, even when it is not in use and even in desktop mode. Why this is the case? I don't know. My assumption is that the keyboard and its individual keys have collisions enabled (probably because of the mallet input), and the physics engine checks if we are colliding with each individual key because of how close we are to them. Having to check for collisions between ~80 moving entities every frame is pretty expensive.

Interesting that something as simple as parenting the keyboard to the avatar in VR could have such large performance impact on desktop mode. The initial fix is just as simple: Only parent the keyboard to the avatar when it is actually in use.

With this issue out of the way, your laptop or old computer should be running Overte a lot better again. The fix will be in the upcoming 2025.03.1 release.

New Dashboard UI

As mentioned in previous progress reports, our upgrade to Qt6 is coupled to a complete UI overhaul. Recently, Ada started work on the new "dashboard", which is planned to replace the current tablet and HUD.

After a bunch of brainstorming, Ada came up with some mock-ups:

And went straight to work, teasing us with screenshots and short video showcases:

Short video showcasing the dashboard.

The new UI will be available in the upcoming months, once our update to Qt6 is finished and stable enough for a release.

Flycam

Another addition by Ada is a new flycam mode, which allows you to more conveniently move your camera around while using the Create app.

Short video showcasing the flycam.

It can be toggled by pressing F4 and will be available in the upcoming 2025.03.1 release.

Currently, there are no plans to remove the Altcam (toggled using the Alt key) or the focus mode, which allows you to focus the camera on an entity by selecting it and pressing the F key.

Sunday Overte Warmup event

I also want to take this opportunity to advertise our "Overte Warmup" event, which takes place every Sunday at 12:30 UTC time.

It begins at 12:00 UTC in VRChat and then switches to Overte at 12:30 UTC. The idea behind it is to spark curiosity in our VRChat friends and bring them over for this occasion.

Keep an eye on the #events channel on Matrix or Discord for up-to-date information about the event.

Website facelift

I finally took the time to give our website a little facelift. The news section used to be just a long text document. This was replaced with ABlog a blogging extension for Sphinx. It makes the news section a little more manageable, without adding much maintenance overhead. While I was at it, I slightly increased the font size and limited the width of the website.

Matrix bridge

I upgraded all of our Matrix rooms to room version 12, which turned out to not be as simple as initially thought. While t2bot (our Matrix↔Discord bridge at the time) supports room version 12, the bridge only worked in one direction.

After trying to self-host and finding out that the bot itself doesn't actually work with room version 12 (t2bot just uses a proxy to change requests), I set out to look for greener pastures. Here come a new bridge which I had never come across on my previous searches for a better bridge: Out Of Your Element It isn't supported by matrix-docker-ansible-deploy which is used for our Matrix server, but the setup ended up being reasonably easy anyway. After a whole bunch of user error on my part, I got Out Of Your Element working on the (at that point) still unsupported room version 12.

The end result has been great. Multiple people commented on how much better the new bridge has been working. As opposed to t2bot, it supports bridging emoji reactions (in both directions), and has been 100% reliable so far. The reliability being a big thing, because t2bot would frequently fail to bridge messages, or take multiple minutes to do so.

Here are Matrix (Element) and Discord side by side:

The Matrix side of our bridge is seeing a lot more usage now than it ever has.

Release version 2025.12.1

Overte version 2025.12.1 was released on the 17th of December. We had been dreading this one for quite a while, because it is a protocol breaking release, meaning that clients and servers are incompatible with previous versions, which made testing a lot harder than usual. Sure enough, we ran into a really weird regression, which only happened in one area of one specific server. Anyone joining and spawning in this area, would get stuck in safe-landing and never finish loading the world around them.

The reason turned out to be as simple as devious: In September we lowered the maximum package size of networking packets (MTU) to fix connection issues for users whose internet providers do not provide them with the usual full size of 1500 bytes. The one server which was having issues had a single entity, which fit into the old package size, but was too large for the new package size. Entities are created on the client and transferred to the server, meaning that it is impossible to create an entity larger than the maximum packet size… unless the maximum packet size changes. Because of this, the server didn't have any safeguards for entities not fitting into a packet and just kept retrying over and over again.

Notice how I said the MTU was changed in September? The 2025.12.1 release wasn't the issue. The server just hadn't been updated until the protocol change required the server to be updated. The issue was actually a rare regression in version 2025.09.1.

Vulkan

The Vulkan backend was finally merged into master. This change has been in development for such a long time, it technically predates Overte itself. Huge thanks to NLnet and the NGI program for sponsoring 74hc595's work on it and huge thanks to 74hc595 and all the people involved for working on this huge undertaking.

While there is still a lot to do, before Vulkan will become our default rendering backend, it is already daily-drivable on Linux. If you want to give it a try, either build Overte from source using the -DOVERTE_RENDERING_BACKEND=Vulkan argument, or download any Vulkan build created by the CI-pipeline, such as this one.

itch.io release

Recently we ran into old regressions, which had not been caught in testing, sometimes for multiple releases, multiple times. This made us think it was time to get some more people on board and open up Overte to a wider audience. Itch.io, with its artist community and people who are used to games made by small teams or single people, seemed like the perfect place to open up to a wider audience, without immediately going all the way to Steam.

I spent a bunch of time designing Overte's itch.io page and even added support for “itch”, itch.io's desktop app, allowing automatic incremental updates. A feature, which none of our other distribution channels have yet.

While I am quite happy with how our itch.io page and the itch app support turned out, there is one issue: itch.io staff appears non-existent. After publishing Overte on the 30th of December, I noticed that it was unlisted. I contacted itch.io's support, and have yet to receive anything more than an automatic “Request received” message. On itch.io's Discord server many other users tell similar stories.

If I saw an open-source project in such a state, I would think it is abandoned or its developer is burned out. With a commercial company, I don't know what to think. Surely they would at least inform people of such long wait times. Whatever the case may be, having Overte on a store just for it to be unlisted isn't very useful. If this continues, we will just have to drop itch.io support again…

Monthly progress report

2025-12-17T00:00:00+00:00

This month, I decided to change it up a bit and report on the progress to date, instead of only to the end of last month.

Overte e.V. general assembly 2025

We held our annual assembly on the 6th of December. The highlights include:

2024 and 2025 both our income and our expenses were way higher than expected.
Our financial prospect for 2026 is good. We should be okay, even if we were to not complete any grant work. (Though donations are always appreciated, since my this assumes my work contract running out at the end of July 2026.)
Our accounting auditor found no issues. As in previous years, they extended their audit into governance and administration and found no issues or new recommendations.
We got a new honorary member within our ranks.
The board can now arbitrarily set the membership fee of non-natural persons (e.g. companies).

A detailed protocol was sent to all Overte e.V. members via email today.

Progress

74hc595 spent way too much time working on way too much stuff again 😉. Taking a break from Qt6, they have resumed work on getting Vulkan merged. (I literally got almost 70 email notification just from the Vulkan Pull Request.) They diagnosed and fixed performance issues which were stalling our upgrade to libnode 22. Of course, they also did their usual spree of general contributions like reviewing and testing Pull Requests, in addition to some smaller PRs.

Ada continued work on their UI overhaul, while also continuing to improve OpenXR support, adding better OSC support, and working on adding local lights to the forward renderer. As always, Ada also did a huge amount of other miscellaneous stuff.

HifiExperiments has been helping with all the graphics related changes and fixed OpenGL ES support.

RTUnreal spent a lot of time bumping their head against more or less random build system issues again.

I (Julian Groß) spent my time with small things as they popped up, including working on the next stable release.

We got a new contributor this month: Zedwick has been helping out with updating the documentation and fixing issues with both the chat and the Nametags app.

Part of the team went on holiday in Warszawa during the first week of December.

Invitation to the Overte e.V. general assembly 2025

2025-11-22T00:00:00+00:00

Saturday, December 6th at 19:00 UTC we will hold our annual general assembly for the Overte e.V. in Overte. While only active Overte e.V. members are allowed to vote, non-Overte-e.V.-members are also welcome to attend.

The planned agenda is as follows:

Decide on assembly leader.
Decide on assembly secretary. The secretary will fill out the protocol during the assembly.
Accounting report for 2024 and 2025.
Budgeting for 2026.
Accounting auditor report (Steve Pruneau).
Do we have someone that would like to become the accounting auditor? The accounting auditor cannot be a board member.
Board report.
Board member elections.
Vote on allowing the board to set membership fees for non-individuals at their discretion. [1]
Vote on hiring Julian Groß as done through board decision on 8th of July 2025. [2]
Vote on by-law change to specifically mention “approval voting” as the used board election system [3]
Protocol gets signed by the assembly secretary and assembly leader.

[1]: Currently, non-individuals (e.g. companies, universities) pay the same 60€ yearly membership fee as everyone else. Some bodies may be willing to pay more but cannot donate due to legal reasons.

[2]: The board already hired Julian Groß in accordance with § 6 The Board (3) Duties ( https://satzung.overte.org/en/#aufgaben ). The assembly should still vote on it to back the board in its decision (or fire me).

[3]    Suggested change to § 6 The Board (4) Election:
From:
(…) Die Vorstandsmitglieder werden von der Mitgliederversammlung pro zu besetzendem Sitz im gesonderten Wahlgang bestimmt. In jedem Wahlgang geben die Mitglieder eine Stimme pro Kandidaten ab. (…)
(…) The board members are elected by the general assembly for each to be occupied seat in separate votes. During each vote, each member has one vote per candidate. (…)

To:
(…) Die Vorstandsmitglieder werden von der Mitgliederversammlung pro zu besetzendem Sitz im gesonderten Wahlgang bestimmt. Das genutzte Wahlverfahren wird auch als Zustimmungswahl bezeichnet: In jedem Wahlgang geben die Mitglieder eine Stimme pro Kandidaten ab. (…)
(…) The board members are elected by the general assembly for each to be occupied seat in separate votes. The used voting system is also referred to as "approval voting": During each vote, each member has one vote per candidate. (…)

Progress

74hc595 again spent most of their time working on upgrading to Qt6. While chasing down crashes on Qt6, they uncovered and fixed multiple old memory safety issues, which have probably been causing issues for years now. Of course, they also did their usual general contributions like reviewing and testing Pull Requests.

Ada spent a lot of time working on their new UI overhaul, which is part of the upgrade to Qt6. Here are some work-in-progress screenshots:

HifiExperiments has been working on a fix for the FBX texture coordinate regression 🔗.

RTUnreal has been fixing C++ build issues, both for Qt6 and our move to C++20. Without him, a lot of maintenance work would be stuck waiting for Qt6 to be finished.

I (Julian Groß) spent most of my time with small bits and bobs, including the stable release, support, finishing the GitHub Actions refactor, and fixing smaller regressions, which were introduced by all the large changes which were merged recently.

Release!

We made another release. Version 2025.10.1 (and 2025.10.1.1 hotfix), which includes only bugfixes; Most importantly, a fix for AppImages crashing on Arch Linux, and a fix for OpenXR support not working on NixOS. It is available here 🔗. After the hotfix, we noticed a packaging issue which caused Fcitx support to not work. This has also be resolved, so get the "Fcitx_support" AppImage if you are having issues with using your IME in Overte.

"AI Cryptocurrency Investment" scammers

Too long; didn't read: We fell victim to scammers and lost >190 €.

September has been a very busy month for me as the accountant. Our organization fell victim to a group of "AI Cryptocurrency Investment" scammers, who try to use our identity to build trust with their targets.

On the 12th of September, we started receiving multiple payments of around 250€ each on our bank account, which were seemed not intended for us. I (Julian Groß) didn't notice these payments initially, as I had already done the monthly accounting and didn't check our bank account. On the 15th of September, we started receiving payments on Stripe, which is our credit card payment provider, as well. Since I got an email notification about those, I knew of them pretty much immediately. Nothing seemed weird there at first; The transactions were using our donation form, so they were clearly labelled as donations. What was odd was that we would suddenly get such large amount of donations in the first place. And, looking closer at them, multiple people were supposedly sharing email addresses. At this point, I started reading through Stripe's documentation and contacted Stripe. Unfortunately, they were very unhelpful. Their documentation suggested this being a card testing scam, and that we should immediately refund everything. Their support was extremely slow, AI translated, and never had anything helpful to say. This is where the first mistake happens as well: I follow Stripe's advice and press the refund button on all the transactions. What I didn't notice at the time, was that Stripe keeps their fees. Meaning that on every refund I make, the Overte e.V. pays a hefty credit card fee. Multiple Euros per transaction. In total, we lost 163,50 € in Stripe fees. Once I noticed this the next day, I started returning only what was left after Stripe's fee. While that saved us from another losing another >100 € in Stripe fees, it ended up incurring a chargeback from one person who really wanted their 1,86 € back. As it turns out, Stripe (and credit card companies) charge 20 € per chargeback. Not to mention the bank responsible for the chargeback graciously rounded up the sum to 1,95 €. Contesting chargebacks incurs another 20 € fee. So I decided to just pay up.

In the meantime, I noticed transactions also going straight to our bank account. This felt way less problematic, since the fees are way lower than for credit card stuff, and we have rule of law there, rather than credit card companies and payment providers just offloading everything onto us. At this point, I got in contact with the Police, since the victims suddenly had names and identities, and as opposed to our Stripe account, I wasn't willing to just close it off. The local Policeman knew immediately what was going on and asked me to inform the victims by sending them messages via SEPA bank transfers. Turns out, instant bank transfers are faster than the police. At least as long as the victims check their bank accounts regularly.

Apparently, this is a very common scam: - The scammers rope their victims in with promises of high-return investment opportunities. - They then have their victims pay a smaller sum to a place that feels trustworthy; In this case, a German bank account. Since it is a German bank account, at least the German victims have little to worry about. If it is a scam, they have someone they can hold accountable. None of this money actually makes it to the scammers. - The scammers then show their victims how much money their investments are allegedly making, and are offering them to invest larger sums. At this point, they have their victims pay money to a channel they have control over. In this latest case published by Eurojust it was mainly Lithuanian bank accounts.

While our bank was slow to respond, they were extremely helpful. They immediately knew what was going on, and offered to screen the transactions for us, meaning I didn't have to return the money manually anymore and didn't have to account for them in our books either, since they never actually make it onto our bank account.

The scam is still going on, but has slowed down considerably. Only one of the scammers appears to remain, and I now know what to do with any fraudulent transactions we receive.

So what did we learn from this? - The saying "Never look a gifted horse in the mouth" doesn't always apply. - We are legally required to pay back any money that wasn't intended for us. (See BGB § 812) - Credit card is an awful way of receiving donations, because it leaves you vulnerable to chargeback and contesting fees, and generally costs way more than even international and inter-currency transfers.

What are the next steps? I am still considering to completely stop accepting donations via Stripe. While the 163,50 € of fees was my fault to some degree, the chargeback fees are something we cannot do anything about with our current setup. Some donators already switched over to donating via bank transfer instead. Meaning that we receive so little money via Stripe now, that just two chargebacks per month are enough to completely negate the money received from there. At that point, I would need to shut that channel down. We could still decide to accept credit card payments via email then; Or maybe we can find some other payment provider who takes over such fees.

If you have any suggestions, questions, or input on this, feel free to reach out via our usual channels.

Infrastructure

Our Weblate translation instance has been slow or inaccessible for most of September due to crappy Chinese AI scraping bots. While this is probably not a deliberate attack, it manifests the same as a distributed denial-of-service attack on our infrastructure.

Anubis has been deployed to our Weblate instance, but unfortunately the low percentage of scrapers that do get through are still occasionally enough to overwhelm the server and flood us with error messages. Due to this, I had to shut down the server for multiple days. While it has been running without issues again for a couple of days now, it might get overwhelmed again until a solution is found.

Weblate added the option to back up individual projects, instead of the entire server, so we are currently looking into moving to a public Weblate instance. So far, this has been a slow process though: - hosted.weblate.org allows creating said backups, but it currently doesn't allow actually restoring them. - translate.codeberg.org doesn't currently support pushing to GitHub and still hasn't made a formal decision if they want to. We also haven't been able to reach their admin yet.

We are not aware of any other public Weblate instances.

There are some other open-source organizations hosting their own Weblate instances, so we might try to join with one of them.

Alternatively, we will just have to upgrade our server and/or pay for something that lets fewer bots through, like Anubis' "Thoth" service.

Progress

74hc595 spent most of their time working on upgrading to Qt6. Apparently, the Qt6 branch already works, even if it is still very unstable. Of course, they also did their usual general contributions like reviewing and testing a lot of Pull Requests.

Ada has been helping with the Qt6 upgrade, focusing on QML related fixes. They also committed some smaller fixes like fixing OpenXR trigger click reliability, in addition to reviewing, testing and reporting bugs, and prototyping their upcoming UI theming support.

HifiExperiments helped with a lot of triage, advice, and code review.

RTUnreal worked up upgrading dependencies and has generally been helping with build system maintenance.

I was mostly busy with handling the recent scam and the flood of broken Chinese AI scrapers. In addition, I worked on refactoring our GitHub Actions workflow files (shoutout to RTUnreal for the code review), fixed some smaller build system bugs and troubleshot regressions. I also started initial work on an itch.io release: Finding regressions introduced multiple releases ago isn't fun and showcases that there just isn't enough testing happening. This suggests that it is about time to try to get more users in. When this release will happen isn't entirely clear yet; We have an upcoming protocol changing release which will undoubtedly introduce more not-yet-known regressions, as well as require all servers and clients to be updated.

We also received bug reports and help from Alezia, Dale, and Krzeszny. Big shoutout also to KawaneRio for organizing Sunday's "Overte warmup" event.

Release!

We made our first release since switching from VCPKG to Conan. Version 2025.09.1 and its changelog are available here 🔗 and come with a huge list of bug fixes, improvements, additions, and changes. It does come with a regression that causes it to crash on many on some Linux distributions when opening a web view, like the Places app. A fix will be included in the next release. For now, affected users can get the CI testing build from GitHub or keep using version 2025.05.1.

Employment

Last post we asked for donations in case unforeseen costs come up with my (Julian Groß) employment. As it turns out, the employment does indeed cost a little bit more (~30€) than I anticipated, costing around 1000€ per month, roughly 710€ of which actually end up on my bank account. (I say “around” and “roughly” because most months cannot be cleanly divided by 4 weeks.)

I want to personally thank everyone who donated. Most of the people who donated appear to be new people who had never even tried Overte before donating. I also want to specially thank our regular donators and paying Overte e.V. members, who keep Overte running. You know who you are, and you rock!

Next time, I should have the donation banner count all money paid towards the Overte e.V., instead of just extra funds on top of the regular donations minus transaction fees. I did it this way for accounting purposes and that was probably just a bad idea.

NLnet grant

In other news, the NLnet Foundation has accepted another grant (amendment) proposal from us. After having been successfully working with them for over 1 1/2 years now, it feels great to still be among all the amazing open source projects supported by them.

We want to thank NLnet and the European Commission for fostering software freedom with their Next Generation Internet programme.

プロジェクト計画

The funding will be used to pay developers to work on the areas listed below.

特徴

Multi-packet avatar updates
linear interpolation for avatar updates
Finish multi-packet entity properties

描画処理

Vulkan frame transfer to VR plugin

メンテナンス

Switch to using a package lock file on Conan and updating it semi-automatically using something like Renovate
Try getting NSIS more foolproof (boolean checks are unreliable as they only check for one possible boolean naming scheme)
Document networking code

Bug Fixes

Fix networking congestion control ( https://github.com/overte-org/overte/issues/572#issuecomment-2799907780 )
Fix retransmissions ignoring congestion control ( https://github.com/overte-org/overte/issues/572#issuecomment-2799907780 )

Entity Transition Shader (Fade)

We have a special shader that makes user appear as if they were "beaming in" or "beaming out" when connecting or disconnecting. Apparently, there is unfinished support for doing this to other entities as well, which we would like to fix/finish and polish. This can be used for multiple purposes, but playing similar animations when people edit worlds, for example by deleting entities, is what got us to look into this.

Add/fix entity transition shader
Expose avatar and entity transition shader as zone properties
Expose entity transition shader to Entities.addEntity and Entities.deleteEntity (overriding zone properties)

macOS support

With the Vulkan PR almost merged into master, Apple getting rid of OpenGL isn't a blocker to our macOS support anymore. However, macOS support was broken for multiple years, always was on the back burner, and we moved build systems in-between, so this is a bit of a larger job. We have a good amount of macOS users who are willing to test, and even some people who are still running our last macOS version, eagerly waiting for a new one.

Get macOS development machine
Build with MoltenVK
Get all of our Conan packages to build on macOS
Fix the server software crashing on macOS
Set up automatic macOS CI builds

Android support

With the new Conan dependency manager, overhauled build system, and experience with Conan, CMake, and our build system, I now feel comfortable tackling Android support. We used to have experimental Android support, but Google changed so much of their build system API for C++ that that part needs to be completely rewritten.

Get all of our required Conan packages to build for Android
Add Android support to our build system
Set up automatic Android CI builds
Add initial OpenXR support to our Android client

Depot.dev

Overte got its first corporate sponsor: Depot.dev 🔗 is graciously providing us with their Continuous Integration services for free.

With us needing to build Qt from source on Windows, the free GitHub hosted Runners were timing out because our builds would take over 6 hours any time there was a Qt package cache miss. So we needed a solution which didn't involve constant babysitting of the CI pipeline, which would have defeated the point of having a CI pipeline in the first place. Getting faster Runners from GitHub would have costed us upwards of 2000€ extra per year, which frankly would have broken the bank.

This is where Depot.dev comes in. Not only are they way cheaper than GitHub hosted Runners and provide a lot more cache space, but they also offer discounts for non-profits and open-source projects.

Interesting enough, even the same spec runners on Depot.dev are actually quite a lot faster at building Overte than the ones on GitHub already.

Progress

Frankly speaking, so much stuff got done this month that I am having a hard time deciding what to mention.

On my side, I have spent most of my time with fixing up our Qt package for Windows and doing more build system improvements. Big thanks to 74hc595 for finding lots of additional issues in my Qt package. 😅 Together, we found out that release builds were actually building with Qt asserts enabled. Asserts are basically deliberate crashes, which exist to make us developers aware of something unexpected happening. They shouldn't be enabled in a release build, as the application often continues to function even when something we didn't expect happens. It's quite frustrating working on something that takes three hours to build any time there is a change on an operating system you aren't usually developing on, but I am quite happy with the results.

Thanks to NLnet, I also started working on macOS support. For now, I got all the required dependencies to build and am waiting for Vulkan to be merged and our update to libnode 22 to be finished.

74hc595 did a lot of work as usual. They fixed multiple audio issues, helped a lot with getting Pull Requests finished, tested and merged, fixed that weird bug with people starting floating while having their camera zoomed into the back of their heads, fixed multiple crashes on Windows, … you get the idea.

Ada also did a lot of miscellaneous bug fixes, but also upstreamed their Context menu, fixed a lot of issues with VR and OpenXR, added OpenXR body tracking support, added multiple new JavaScript APIs, et cetera. We keep merging Pull Requests and Ada keeps opening new ones.

HifiExperiments added initial VRM file format support, fixed remaining issues with his new multi-layered materials, and helped Ada and 74hc595 with graphics work as usual.

Alezia worked on improving the Snap app, added bookmarks and per-Place user counts to the Places app, and cleaned up the Places app's code.

We also got a new contributor this month: RTUnreal started work on packaging Overte for NixOS. To that end, they already added support for our build system to use only system libraries, uncovered and fixed some bugs, and have been a huge help with the libnode 22 upgrade. Considering how many people already dabbled with trying to build Overte using Nix and gave up once they realized how much work it is going to be, it is especially great to see RTUnreal get changes merged into Overte.

Release candidate!

On the topic of progress: We tagged our first release candidate since switching from VCPKG to Conan. Version 2025.09.1-rc1 and its changelog are available here 🔗 and come with a huge list of bug fixes, improvements, additions, and changes. So far, this release candidate has been rock solid, so it might turn into a full release already next week without any additional changes necessary.

Help us hire a team member!

2025-06-07T00:00:00+00:00

We are in the process of hiring our long-term contributor Julian Groß, allowing him to dedicate more time to Overte and get things done.

The current proposal is a one-year-long contract for 13 hours per week at German minimum wage. While not much, this is enough for Julian to survive and make work on Overte his main profession.

However, while the Overte e.V. can technically afford that, we are cutting it close. That is why we are asking for your support!

We need to keep some financial cushioning in case of unforeseen costs, so we are doing our first fundraiser to reach our goal of 3000€ of additional funds over the next couple of months.

Chat messages in 3D space (https://github.com/overte-org/overte/issues/1147)
Add copy and paste buttons to VR keyboard (https://github.com/overte-org/overte/issues/130)
Support OpenXR finger tracking (https://github.com/overte-org/overte/issues/224)
Cryptography functions in scripting API (https://github.com/overte-org/overte/tree/feature/cryptography)
チャットにリアルタイムライブ翻訳機能をサポートする

描画処理

当エンジンの内部では独自の描画処理用のグラフィックスAPIを使用しておりますが、この仕様は殆どドキュメント化されておりません。この API のドキュメント化は大変な作業となりますが、プロジェクトの将来的な保守性を確保する上で必要になります。さらにVulkanの最適化、特にIntel Arcグラフィックスカードにおけるパフォーマンスの問題解決にも、より多くの時間を割きたいと考えています。

Vulkan の最適化
内製グラフィック API のドキュメント化
Have local lights affect MToon materials (https://github.com/overte-org/overte/issues/1131)
Expose normal map attenuation distance as zone property (https://github.com/overte-org/overte/issues/1139)
Use standard physically-based-rendering for voxels (https://github.com/overte-org/overte/issues/749)
コマンドラインオプションを利用してグラフィックス API を切り替えられるようにする
Add splat mapping functionality (https://github.com/overte-org/overte/issues/1163)
Add a no-filter texture filtering mode (https://github.com/overte-org/overte/issues/145)

QML のローカライズ

Overte は世界中の方々に利用されているため、ローカライズ機能を実装したいと考えております。このタスクは QML を使用して作成された全ての内部 UI の翻訳を可能にする目的があります。(当団体の UI は殆ど QML を使用していますが、全てではありません。)

文字列を翻訳可能としてマークする
翻訳ファイルの自動生成
Weblate 翻訳ファイルに接続する
翻訳を含めてビルドする
必要なフォントが含まれているか確認する
ドイツ語翻訳の追加(テストケースの実装)

メンテナンス

CMake 4.0 が間も無くリリースされます。これにより一部のレガシー互換性がサポートされなくなるため、当ソフトウェアの依存関係の大半が機能しなくなる可能性があります。Libnode も更新され、互換性を損う変更を含みます。

Overte をCMale 4.0 に対応するための更新
CMake 4.0 に対するビルド依存関係の修正
libnode を次の LTS 版に更新する
KDevelop と CLion を使用したビルド手順を改善する
Docker の自動リリースビルドを追加する
Overte を Flathub に追加する作業の完了
Update to Qt 6 (https://github.com/overte-org/overte/issues/1243)
Windows 用の Qt6 パッケージの依存関係
Linux 用 Qt6 パッケージの依存関係
Package webrtc-audio-processing
Switch to libdatachannel

2024年4月16日 NLnetの助成金が再び拡充されました！

2024-04-16T00:00:00+00:00

NLnet様からの助成金の拡充が再び認められ、以下の追加項目が盛り込まれました：

メンテナンス

警告を修正し、「警告をエラーとして扱う」設定を有効にできるようにする（https://github.com/overte-org/overte/issues/930）
Application.cppを整理して10,000行未満にする（https://github.com/overte-org/overte/issues/931）
「名前によるジョイントデータの設定」の修正（https://github.com/overte-org/overte/issues/613）
コードの重複を解消するため、従来のウェアラブルシステムをアバターエンティティに置き換える（https://github.com/overte-org/overte/issues/932）

テキストエンティティ

テキストエンティティには改善の余地があります。それらは扱いにくく、何よりどこにもドキュメント化されていない独自のフォーマットを使用しているからです。つまりは新しいフォントを追加できないということですが、現在のフォントはASCII文字にしか対応していないため、これが重要な課題となっています。

完全に消えてしまうのではなく、端で切り取られるようにする（https://github.com/overte-org/overte/issues/583）
標準的なフォント形式への切り替え（https://github.com/overte-org/overte/issues/126）

グラフィックの改善（第二弾）

アンビエントライトカラーの追加（https://github.com/overte-org/overte/issues/6）
MToonマテリアルのglTFからの直接読み込み（https://github.com/overte-org/overte/issues/933）
カメラクリッピングのオプション（https://github.com/overte-org/overte/issues/618）
カスタムシェーダーのフォールバック (https://github.com/overte-org/overte/issues/640): シェーダーの読み込み失敗やコンパイル失敗時のフォールバックとユーザーがプロシージャルシェーダーを無効にしている場合のフォールバック
グラフィック設定の追加。(トーンマッピング、ブルーム、プロシージャルシェーダー、AO)(https://github.com/overte-org/overte/issues/740, https://github.com/overte-org/overte/issues/741, https://github.com/overte-org/overte/issues/14)
ゾーンエンティティにトーンマッピングおよびアンビエントオクルージョンのプロパティを追加する（https://github.com/overte-org/overte/issues/934）

その他改善点（第二弾）

手が震えやすい人にとって特に役立つ、VRレーザー手振れ補正機能を追加（https://github.com/overte-org/overte/issues/883）
アバターエンティティの読み込み優先度を上げる（https://github.com/overte-org/overte/issues/834）
エンティティが読み込まれるまでアバターを表示しないオプションを追加する (https://github.com/overte-org/overte/issues/834)
現在の読み込み優先順位システムの改善（https://github.com/overte-org/overte/issues/834）
エンティティに読み込み優先順位プロパティを追加する（https://github.com/overte-org/overte/issues/834）

2024年4月2日 NLnet様からの助成金が拡充されました！

2024-04-02T00:00:00+00:00

NLnet様からの助成金の拡充が認められ、以下の追加事項が盛り込まれました：

Linux ファイルシステム階層標準(FHS)のサポート

Linux ファイルシステム階層標準(FHS)はアプリケーションに適したファイル構成を定義するものです。この作業では Linux FHS を採用するとともに、いくつかの改良を加えることが含まれています。

次のように:

バッケージングをより簡単にし、ディストリビューションへの組み込みを可能にします。
SELinux をより使いやすくします。
導入してからすぐにインスタンシングができます。
macOS上のパッケージングを簡単にします。

作業内容:

ドメインサーバ及び割り当てクライアントの実装 (https://github.com/overte-org/overte/issues/903
インターフェースの実装 (https://github.com/overte-org/overte/issues/904)

LDAP のサポート

LDAP は一般的な認証方法であり、多くの団体で採用されています。Active Directory も同様に互換性があります。

これにより Overte は企業や大学のシステムとより統合しやすくなりました。各組織で自前の内部システムを使用して認証管理することも可能です。そうすれば、私達がそのコードを書く必要はなくなるでしょう。その作業はあまり意味がなく、他のプロジェクトの方が良い実装をしているからです。

作業内容:

ドメインの WebUI における複数のユーザー認証を可能にする基本的な機能のサポート。(https://github.com/overte-org/overte/issues/905)
ディレクトリサーバの代替となる基本的機能の実装:ユーザアカウント、ドメインディレクトリ (https://github.com/overte-org/overte/issues/906)
ディレクトリサーバの完全な代替の実装。user relationships やデータストレージ、プロファイルのメタデータのサポート。(https://github.com/overte-org/overte/issues/907)

IPv6のサポート

近年、IPv6の普及率がかなり上昇しており、特に企業や大学、SaaS等のクラウドコンピューティングや大規模な導入環境における、IPv4アドレスが枯渇している環境ではその重要性が際立っています。既にIPv4アドレスの使用に追加料金を課すプロバイダも存在しているため、ドメインのホスティング費用を抑えることができます。

作業内容:

ドメインWebUIの基本的なサポート (https://github.com/overte-org/overte/issues/908)
インターフェースにおけるIPv6環境でのアセット取得のサポート (https://github.com/overte-org/overte/issues/909)
IPv6環境上で動作するドメインのサポート。 (https://github.com/overte-org/overte/issues/910)

SELinux

SELinux はアプリケーションやデーモンをサンドボックス化できるセキュリティシステムです。

SELinux はドメインサーバを(必要に応じインターフェースも)サンドボックス化し、エクスプロイトを受けた場合でもシステムの他の箇所に影響を及ぼさないようにします。例えばドメインの脆弱性を悪用されたとしても、そのドメインを機能不全にすることができますが、そのサーバを踏み台にして他のコンピュータを攻撃したり、ユーザの個人情報を流出することは不可能になります。

作業内容:

ドメインサーバを制限する (https://github.com/overte-org/overte/issues/69)
割り当て先の制限の実装。(https://github.com/overte-org/overte/issues/912)
分離機能を備えた複数インスタンスサポートの試行。 (https://github.com/overte-org/overte/issues/913)
同一環境上の複数の Overte サーバを互いに分離する。 (https://github.com/overte-org/overte/issues/914)
インターフェイスの限定 (https://github.com/overte-org/overte/issues/915)

キャンバステクスチャ

これにより、ソフトウェア定義のキャンバステクスチャという新たな概念が実装されます。スクリプトはこの上に描画でき、クライアントは更新情報を受け取ります。

これには、膨大で幅広い有用な機能の可能性が秘められています:

ソフトウェア定義のテクスチャ
スクリプトによって生成された名札、バナー、ステータス表示など。
外部の依存なしでの画像の共有
ホワイトボード
同期された Web エンティティ
サーバサイドでレンダリングされる Web エンティティ。これにより Quest の実装が進むでしょう。

作業内容:

テクスチャオブジェクト、ピクセルやブロック描画といった簡単な操作といった基本的な実装。(https://github.com/overte-org/overte/issues/916)
本格的なキャンバス API の実装。フォントや矩形、円や曲線などのグラフィックプリミティブに対応。(https://github.com/overte-org/overte/issues/917)
画面共有の実装 (https://github.com/overte-org/overte/issues/918)
同期されたWeb画面への対応 (https://github.com/overte-org/overte/issues/919)

2024年2月24日 NLnet 様から助成金が支給されました！

2024-02-24T00:00:00+00:00

NLnet Foundation は、多くの素晴らしいオープンソースプロジェクトを支援する組織であり、私たちもその中の一つに選ばれたことを喜んでお知らせします！

As part of the agreement, we commit to keeping users and developers up to date with the progress made on these items at least every two months. For that, we'll keep track of it during our usual Saturday development meetings, and use tags, projects and other functionality on GitHub to make it easy for anyone interested to follow the progress.

プロジェクト計画

この資金は、以下の分野で作業する開発者の給与に使用されます。私たちと NLnet の間でさらなる作業が合意される可能性があります。

締め切りは 2025年2月17日です。

一部の作業はすでに開始されており、 GitHub にて確認できます https://github.com/overte-org/overte

音声関連の徹底的な見直し

音声領域を領域設定へ移行させる (https://github.com/overte-org/overte/issues/69)
音声エンティティの追加 (https://github.com/overte-org/overte/issues/69)

その他改善点

Web エンティティに wantsKeyboardFocus プロパティを追加する (https://github.com/overte-org/overte/issues/6)
モデルアニメーションにインターポレーションを追加する (https://github.com/overte-org/overte/issues/317)

グラフィックの改善

背面の影カリングの修正 (https://github.com/overte-org/overte/issues/547)
不透明(opaque)パーティカルの許可 (https://github.com/overte-org/overte/issues/776#issuecomment-1868203856)
ベロシティバッファつき TAA アンチエイジングの見直し作業の完了 (https://github.com/overte-org/overte/pull/501)
GPU パーティカルのサポート

Vulkan

私たちは現在、3DレンダリングにOpenGLを使っています。しかし残念なことに、ここ数年で人気がなくなり、Macのようないくつかのプラットフォームでは完全に非推奨となっています。 AMDはOpenGLにほとんど注意を払っておらず、ドライバのバグが頻繁に悩みの種になっています。

Vulkanは、より現代的でパフォーマンスが高く、サポートされているレンダラーを提供し、Macサポートの問題を解決するでしょう。

ワイヤフレームのレンダリング
Forward レンダラー(ローエンドハードウェア向け)
遅延レンダリング(十分な性能を持ったハードウェア向け)
最適化
VR プラグインへのフレーム転送

ビルドシステムの改良

Overteでの作業がより楽になり、ビルドが簡単になります。これは、メンテナンスを円滑にし、将来のプロジェクト貢献者の負担軽減のために重要なものとなります。

Conanへの切り替え
ドキュメンテーションの更新🔗
ビルドプロセスの改善
