Small video of the Cloth bits animated correctly in bvh

In DS2 and DS3, there are no perfect mirrors, but in fights like alonne arena, where high quality planar reflections are rendered, those are used with RT/SSR as fallback

Diffuse lighting this is not an issue as you are looking for "Avg color bleed" which works great, but in mirror like situations higher quality i.e direct texture sampling is possible, but this is primary way to get the "material data", the roughness/metallicity/alpha is also baked there.

Yeah correct, rays can intersect any part of world, in the "ideal" scenario, material textures need to be sampled at ray hit, but this can get really expensive fast. So the RT World BVH is used to store the colors at vertex level,

Thank you :)

This image is completely lit by bounce lighting. Includes Skinned characters

Thank you :)

Debug Specular GI View

Thank you

Here are some more images, Now I have something to work with, lots of BVH work pending like all builds being scheduled on async queue , putting animated characters as well in there. Last image is just some tests to check double reflections

Adding on top of this. Added multiple different debug views to understand issues quickly similar to how there are debug views for raster.

Thanks Alex :).
