The Rust powered open source 2D/3D ECS based game engine Bevy just released Bevy 0.13. This release comes a mere 3 months since Bevy 0.12 and contains hundreds of changes and improvements. Highlights of the Bevy 0.13 release include:
- Lightmaps: A fast, popular baked global illumination technique for static geometry (baked externally in programs like The Lightmapper).
- Irradiance Volumes / Voxel Global Illumination: A baked form of global illumination that samples light at the centers of voxels within a cuboid (baked externally in programs like Blender).
- Approximate Indirect Specular Occlusion: Improved lighting realism by reducing specular light leaking via specular occlusion.
- Reflection Probes: A baked form of axis aligned environment map that allows for realistic reflections for static geometry (baked externally in programs like Blender)
- Primitive shapes: Basic shapes are a core building block of both game engines and video games: we’ve added a polished, ready-to-use collection of them!
- System stepping: Completely pause and advance through your game frame-by-frame or system-by-system to interactively debug game logic, all while rendering continues to update.
- Dynamic queries: Refining queries from within systems is extremely expressive, and is the last big puzzle piece for runtime-defined types and third-party modding and scripting integration.
- Automatically inferred command flush points: Tired of reasoning about where to put
apply_deferredand confused about why your commands weren’t being applied? Us too! Now, Bevy’s scheduler uses ordinary.beforeand.afterconstraints and inspects the system parameters to automatically infer (and deduplicate) synchronization points. - Slicing, tiling and nine-patch 2D images: Ninepatch layout is a popular tool for smoothly scaling stylized tilesets and UIs. Now in Bevy!
- Camera-Driven UI: UI entity trees can now be selectively added to any camera, rather than being globally applied to all cameras, enabling things like split screen UIs!
- Camera Exposure: Realistic / “real world” control over camera exposure via EV100, f-stops, shutter speed, and ISO sensitivity. Lights have also been adjusted to make their units more realistic.
- Animation interpolation modes: Bevy now supports non-linear interpolation modes in exported glTF animations.
