The thing with vrc light volumes is that people have seen this kind of things before, but they don't realize how much faster it is compared to other solutions. You can easily use this in android quest 2 worlds with very little performance penalty.
I'm working on a new major VRC Light Volumes update!
- Baked realtime shadows (very performant)
- Animated cookies and cubemaps
- Optimized area lights
- No more legacy code
- Almost full back compatibility with older light volumes shaders (excluding new shadows)
