New Bakery version uses OptiX9 library instead 6.
OptiX9 API is massively different to OptiX6. The "fix" was comparable to porting a DX9 game engine to DX12 😅
But on the other hand, it's now much more efficient and in retrospect I see why NV wanted to deprecate 6...

I couldn't find any notice of optix6 being officially deprecated so I HOPE it's a temporary bug.

you can also use morton order as your 'hash' function to increase cache coherence even more. we used this all over dreams. admittedly not in an ao caching context, but one where build rates were lower. but, still worth a read in case it sparks any ideas in your head. its one of my faves ever

Nice!
How are the blobs applied though? Are they computed inside the receiver's pixel shader? In a loop? Or multipass with blend? Or deferred? Or...

Additional important note: Light Filter meshes still receive diffuse lighting as any other lightmapped objects. Not visible on my video because I'm using a simple multiply-blend shader, but you can sample lightmaps on them (make a dusty stained glass?)
