We are back roughly a month after the release of dev3 to bring you a host of new improvements. Many of our developers traveled to Germany in October for GodotCon and the yearly Godot contributor meeting. There they spent two days discussing some of the biggest technical challenges and puzzling out solutions. 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).

Interactive in-game editing One of the most requested features is the ability to debug the running game from within the editor including pausing the game, clicking on elements within the scene, and embedding the running game window inside the editor. Dev4 comes with the first two of these workflows thanks to the contribution from YeldhamDev of Lone Wolf Technology & W4 Games, users are now able to explore their project’s world freely! YeldhamDev The actual embedding of the game window into the editor will come later in a subsequent PR. Check out the PR (GH-97257) and the video below to see exactly what this change enables. GH-97257 Use collision detection ray to reposition an object already in the scene ryevdokimov added object snapping for placing 3D objects in the editor (GH-96740). ryevdokimov GH-96740 This is not a drill, see below. Ubershaders and pipeline pre-compilation (and dedicated transfer queues) This change combines 2 huge improvements (GH-90400): GH-90400 Ubershaders: a technique that allows us to completely avoid shader stutter when objects are viewed in a scene for the first time
Dedicated transfer queues: by relying on special hardware functions we can dramatically improve the load time for scenes containing many graphics assets like meshes and textures. Ubershaders: a technique that allows us to completely avoid shader stutter when objects are viewed in a scene for the first time Dedicated transfer queues: by relying on special hardware functions we can dramatically improve the load time for scenes containing many graphics assets like meshes and textures. Thanks to DarioSamo for months of hard work on this. The implementation of Ubershaders is something that took a lot of design and implementation to get right, but the end result is something we are very happy with. DarioSamo “Ubershaders” are a version of each shader that contains all features and are compiled at load time. We pair the ubershader with the ability to compile specialized shader pipelines in the background. This way when we draw a new object, instead of freezing and waiting for the pipeline to compile, we fallback on the ubershader and compile the specialized shader in the background. Most games will notice the improvement from ubershaders without any content changes. However, there are certain cases where the ubershader won’t work and some content changes will be needed to avoid shader stutter. However, the workarounds for avoiding shader stutter are now very simple and are well documented already in the official docs. official docs Taking advantage of the new ubershader infrastructure, we can now optimize our shaders by creating specialized variants that skip unused pathways. We have already begin doing so to optimize our existing shaders (GH-98825). GH-98825 Add Shadow Caster Mask property to Light3D This long awaited improvement from EMBYRDEV allows users to apply a mask on Light3Ds to select what rendering layers will be considered when casting shadows (GH-85338). Previously it was only possible to disable shadows from a GeometryInstance (for all Light3Ds) or a Light3D (for all GeometryInstances). This allows much more fine-grained control that allows users to further optimize dynamic lights and control where shadows appear in their games. EMBYRDEV GH-85338 Always add decimal when converting float to string Currently when printing float values Godot trims trailing .0s as they are technically unnecessary. However, this could lead to issues for users who need to distinguish between floating point numbers and integers. KoBeWi has now changed the behavior when floats are converted to strings to always add the decimal number, even if it would be .0. This makes floats always recognizable when they are converted to strings (GH-47502). .0 KoBeWi .0 GH-47502 This change in behavior may break your project if you are relying on the current serialization behavior. If this change breaks your project, please let us know by opening an issue on GitHub. # Before:
