We are back with another big dev update with over 330 commits merged in the last few weeks! Contributors continue to work on amazing new things while we continue to merge our backlog of important features that missed the 4.3 cutoff. The combined result is a lot of great stuff compressed into a short amount of time. Many of the changes in this release are bug fixes that will be backported to Godot 4.3 and released in 4.3.1! So please test this release well so we can be confident with the changes and release 4.3.1 with them as soon as possible. Keep in mind that while we try to make sure each dev snapshot is stable enough for general testing, this is by definition a pre-release piece of software. Be sure to make frequent backups, or use a version control system such as Git, to preserve your projects in case of corruption or data loss. Jump to the Downloads section, and give it a spin right now, or continue reading to learn more about improvements in this release. You can also try the Web editor, XR editor, or the Android editor for this release (join the Android editor testing group to get access to pre-release builds).

GH-96290 jordi-star Macksaur Ernest Danil This new feature allows you to be even more expressive with the dev tooling that you can easily create with @tool scripts. @tool Let’s take a look at an example: @tool
extends Sprite2D

# With a callable (could also be a local function).
@export_tool_button("Toot", "Callable")
var print_action = print.bind("toot")

# With a lambda.
@export_tool_button("Randomize Color", "ColorRect")
var color_action = func(): self_modulate = Color(randf(), randf(), randf()) @tool
extends Sprite2D

# With a callable (could also be a local function).
@export_tool_button("Toot", "Callable")
var print_action = print.bind("toot")

# With a lambda.
@export_tool_button("Randomize Color", "ColorRect")
var color_action = func(): self_modulate = Color(randf(), randf(), randf()) Massively optimized scene startup for large projects Work has not slowed down on improving the scene startup experience, still thanks to amazing contributions by Hilderin. This dev snapshot introduces a massive improvement to editor load speed for large projects (GH-95678). Large projects can expect up to a 3× speed improvement when loading the project and a similar speedup when doing any operations that scan the filesystem. Hilderin GH-95678 Vertex shading This dev release re-introduces the long-awaited vertex shading option for materials (GH-83360), thanks to contributor ywmaa landing their second major feature in Godot, after export support for Blender Geometry Nodes. Vertex shading is used primarily to achieve an early PSX style and to optimize performance on older and lower-end devices. GH-83360 ywmaa Blender Geometry Nodes You can enable vertex shading either from within an existing StandardMaterial3D, ORMMaterial3D, ShaderMaterial, or by force enabling it on all materials using the rendering/shading/overrides/force_vertex_shading project setting. StandardMaterial3D ORMMaterial3D ShaderMaterial rendering/shading/overrides/force_vertex_shading Add batching to RendererCanvasRenderRD After tackling the Metal rendering backend merged in an earlier snapshot, Stuart took on another impressive rendering contribution: 2D batching! Metal rendering backend Stuart Batching has been implemented in the Compatibility renderer since the release of 4.0. This release brings the same performance benefits to the other backends by implementing batching when using the Forward+ and Mobile backends (GH-92797). Now 2D performance is comparable between all backends. GH-92797 Batching is a performance optimization that drastically reduces the number of draw calls in a scene. The benefits of batching will be particularly noticeable in scenes with a lot of text rendering or repeated sprites that share a texture (e.g. when using tilemaps or making a bullet hell). We have further improvements planned for batching on the RD backends that should allow it to be even faster than the Compatibility backend. Stay tuned for updates in later dev releases! Expression evaluator (REPL) in the debugger The expression evaluator adds a new tab to the bottom panel that allows you to evaluate expressions using the local state of your scripts while stopped at a breakpoint. Many users are familiar with this workflow from other REPL debuggers. REPL This feature has been a work in progress for awhile and was recently finished and merged in (GH-97647), thank you to Oğuzhan, Erik, and Tomek for bringing it across the finish line. GH-97647 Oğuzhan Erik Tomek Implement autostart for all profilers A common complaint from users is that they need to go back to the editor once they start their game in order to enable the profiler. This made it hard to measure performance in the first few seconds of loading a scene and was an overall hassle for developers. Hendrik introduced a checkbox that allows you to set the profiler to automatically start when you run the engine and capture valuable profiling data immediately (GH-96759). Hendrik GH-96759 Add markers to Animation Markers allow you to create sub regions of an animation that can be jumped to, or looped without playing the entire animation. Markers are even supported inside the Animation Tree, where you can easily select animation markers for looping or to begin playback. For more details check out the pull request GH-91765, which was one of the first Godot contributions of ChocolaMint! GH-91765 ChocolaMint Linux camera support Previously, Godot only supported accessing the device camera on macOS and iOS devices. pkowal1982’s long-running pull request GH-53666 was finally merged and adds support for the Linux platform, allowing developers to access connected cameras from within their game. pkowal1982 GH-53666 Fallback to OpenGL 3 if other rendering drivers are not supported Currently when trying to run Godot with the Forward+ or Mobile backend on a device that doesn’t support Vulkan, D3D12, or Metal, the engine will provide the user with an OS alert notifying them that they don’t have support for the needed graphics API and they need to try again with the Compatibility backend. This alert has proven to be confusing for users and the process of opening the scene ends up being cumbersome. Now with GH-97142, first contribution from SheepYhangCN, the engine will automatically fall back to using OpenGL (the Compatibility backend) when the other backends are not available. This should provide the smoothest possible experience for users on older devices. GH-97142 SheepYhangCN Since the Compatibility backends can look different from the other backends, game developers may not want Godot to automatically fall back. In that case, they can disable the rendering/rendering_device/fallback_to_opengl3 project setting to avoid falling back, and users with OpenGL-only devices would then get notified that their hardware is not supported. rendering/rendering_device/fallback_to_opengl3 And more!
