All I can say I got done in this long session is I optimized the rendering slightly. Not the tracing, just the regular lighting by catching the light colors (since they are from the scattered sky) in a tiny 2x2 texture, but it did give me 80+ fps back when I look at the ground at least. I will also have to redo all the BVH setup and actually learn how to do it all since I was leaning a bit heavy on AI use and something broke somewhere and I couldn’t figure out where. Time to actually code it all QwQ (not really sad, probably a good idea to actually learn it fully)
