Release candidate: Godot 3.5 RC 2
By: Rémi Verschelde 24 May 2022
The upcoming Godot 3.5 is now considered feature complete, and has received a lot of bugfixes and improvements over the past weeks thanks to all the testers and developers who reported and fixed issues. It's now time to move to the Release Candidate stage so that we can release 3.5-stable for all users.
At this stage we need people to test this release (and potential follow-up RCs) on as many codebases as possible, to make sure that we catch non-obvious regressions that might have gone unnoticed until now. If you run into any issue, please make sure to report it on GitHub so that we can know about it and fix it!
This RC 2 includes a few important changes that will require particular testing - the RC stage is typically too late to do such changes, but they were either self-contained or critical enough for exceptions to be made:
- Windows binaries are now built on Fedora 36 instead of Fedora 35, which seems to fix a GCC regression that would trigger crashes (GH-51070, GH-61176).
- A long-standing Bullet regression has finally been fixed (GH-56801), solving issues with KinematicBody collisions on edges (e.g. seen as small bumps between tiles on a GridMap). The fix seems relatively safe but this will require heavy testing to make sure it doesn't regress - if you have 3D games using Bullet physics, please try this RC 2 and report any issue.
- New Label3D (GH-61276) and TextMesh (GH-61281) nodes have been backported from Godot 4.0. They're self-contained so there's little risk of regression, but please test them thoroughly anyway.
As usual, you can try it live with the online version of the Godot editor updated for this release.
The main changes coming in Godot 3.5 and included in this release candidate are:
Asynchronous shader compilation + caching (ubershader) (GH-53411)
A long awaited solution to shader compilation stuttering on OpenGL, courtesy Pedro J. Estébanez (RandomShaper)!
This new system uses an "ubershader" (big shader supporting all features, slow but compiled on startup) to fill in for all shaders initially while the more efficient and material-specific shaders get compiled asynchronously, and cached for future runs.
This means that on the first run materials may look a bit different for a second or two, but there should no longer be compilation lags. Please test this thoroughly and let us know how it performs on your projects.
Add NavigationServer with obstacle avoidance using RVO2 (GH-48395)
Jake Young (Duroxxigar) backported the refactored and much improved navigation system that Andrea Catania (AndreaCatania) implemented for Godot 4.0 back in 2020! And then a lot of old and new navigation issues have been fixed by smix8 and Pawel Lampe (Scony).
The new NavigationServer adds support for obstacle avoidance using the RVO2 library, and navigation meshes can now be baked at runtime. The whole API is now a lot more flexible than it used to be.
The backport was done while attempting to preserve API compatibility within reason, but the underlying behavior will change, mainly to provide a lot more features and flexibility. We expect that all users will happily move to the new NavigationServer, but please report issues if you see behavior changes for the worse when upgrading from 3.4.
Physics interpolation (3D) (GH-52846)
In Godot, while physics runs at a fixed tick rate, frames can actually display at a wide variety of frame rates, depending on the player's hardware. This can lead to a problem, when the movement of objects (which tends to occur on physics ticks) does not line up with the rendered frames, giving unsightly jitter.
Thanks to lawnjelly's expertise, you will now find a sweet new option hidden in the project settings. Switch on
physics/common/physics_interpolation, and Godot will now automatically interpolate objects on rendered frames so they look super smooth.
In order to benefit you should be moving your objects and running your game logic in
_physics_process(). This ensures your game will run the same on all machines. Full details are available in the updated docs.
Fixed timestep interpolation is 3D only for now, but watch this space as we plan to add 2D support after initial feedback and bugfixing on the 3D version.
OccluderShapePolygon (3D) (GH-57361)
Following on from the addition of OccluderShapeSphere in 3.4, lawnjelly now brings us a more adaptable and easy way to add basic occlusion culling in the form of the OccluderShapePolygon. Add an Occluder node to your scene, and choose to create an OccluderShapePolygon. This should show up initially as a quad.
You can move the polygon with the node transform, drag the corners to reshape it, add delete points. Anything behind the polygon will be culled from view.
It is really as simple as that to get started, place them wherever you like in your game level. Read the updated docs for details.
Android editor port (GH-57747)
Two years ago (!), thebestnom started working on an Android port of the Godot editor (GH-36776). Since the Godot editor is built with Godot itself, it wasn't too difficult to imagine compiling the editor for Android with some buildsystem changes. But a lot of work was needed to actually make this compiled version work decently on an Android device, with improved mouse and keyboard support, better touch input, as well as being able to run the project on top of the editor like on desktop.
With a lot of testing from interested users, things progressed slowly but steadily, and our Android maintainer Fredia Huya-Kouadio (m4gr3d) put the finishing touches to get this work merged for Godot 3.5 (GH-57747). The current version doesn't have a lot of mobile specific changes, so it's only really usable on a tablet with keyboard and mouse - but the foundation is there to improve upon, and we're interested in your feedback and ideas son how to make the Godot experience more mobile friendly!
From now on you'll find builds of the Android editor as
<godot_version>_android_editor.apk in the download repository. Note that builds are currently not signed, so you will get a warning on install. Give it a try!
With helpful input from contributors Dan Edwards (Gromph) and Péter Magyar (Relintai), Fredia was also able to fix the low processor usage mode on Android (GH-59606), which the editor port uses. It should now work fine for users who make non-game applications or non real-time games on Android and want to preserve battery life.
Long awaited, Godot now provides a Label3D node out of the box to display text in 3D scenes. And for more advanced use cases, there is now also TextMesh to generate 3D meshes from font glyphs, so you can add Word Art to your scenes ;)
Both features were implemented by our text rendering expert bruvzg in the
master branch for Godot 4.0, and backported to 3.5. They were merged late in the release process (3.5 RC 2) but should be quite self-contained and thus not impact the stability of other features. Be sure to test them and report any bug or inconvenience with the implementation.
New SceneTreeTween backported from Godot 4.0 (GH-60581)
Tomasz Chabora (KoBeWi) completely overhauled the Tween class in Godot 4.0 to make it a lot more powerful and flexible. Early testers so far seemed to like, and Haoyu Qiu (timothyqiu) decided to backport the feature to Godot 3.5 as
SceneTreeTween (to keep the pre-existing
Tween and thus preserve compatibility). So you now have two separate Tween implementations and can use to keep using the original 3.x one, or adopt the new API from 4.0.
Scene unique nodes (GH-60527)
To help with the common task of accessing specific nodes from scripts, Juan Linietsky (reduz) added the concept of "scene unique names" for nodes in the
master branch (GH-60298), and Tomasz backported it for 3.5. Nodes with a scene unique name can be referenced easily within their scene using a new
% name prefix, like so:
get_node("%MyUniqueNode"). This is particularly useful for GUI if you need to locate a specific Control node which might move in the scene tree as you refactor things.
Add push, pull, fetch and improved diff view to VCS UI (GH-53900)
What is it? A lot of new features for Version Control Systems (VCS) integration in the Godot editor, such as push, pull, and fetch operations, as well as a very nice diff view UI. All these features have been implemented in the official Git integration plugin. Check out the Releases page for the latest 2.x plugin release supporting Godot 3.5.

There's no curated changelog just yet, I still have to skim through all commits to select the changelog worthy changes.
You can also review the changes between RC 1 and RC 2.
This release is built from commit 5f9bc7ea5.
The downloads for this dev snapshot can be found directly on our repository:
- Standard build (GDScript, GDNative, VisualScript).
- Mono build (C# support + all the above). You need to have dotnet CLI or MSBuild installed to use the Mono build. Relevant parts of Mono 220.127.116.11 are included in this build.
As a tester, you are encouraged to open bug reports if you experience issues with this release candidate. Please check first the existing issues on GitHub, using the search function with relevant keywords, to ensure that the bug you experience is not known already.
In particular, any change that would cause a regression in your projects is very important to report (e.g. if something that worked fine in 3.4.x no longer works in this 3.5 RC).
Godot is a non-profit, open source game engine developed by hundreds of contributors on their free time, and a handful of part or full-time developers, hired thanks to donations from the Godot community. A big thankyou to everyone who has contributed their time or financial support to the project!
