I've been working on raytraced lighting in the Bevy game engine, using wgpu's new support for hardware raytracing in WGSL. The initial prototype is launching with the release of Bevy 0.17 tomorrow, but there's still a ton left to improve. Lots of experimenting with shaders and different optimizations.
I wrote a blog post about my initial findings recently: https://jms55.github.io/posts/2025-09-20-solari-bevy-0-17
