There is a presentation about Lumen from SIGGRAPH 2021 :
" Radiance Caching for Real-Time Global Illumination"
and at the end shows a few pictures. Most are made with “half a ray per pixels” but there are a few with 2 rays per pixel for a much higher quality.
First picture attached is with half a ray and the second is with 2 rays per pixels.
What are the cvars or the controls in Lumen to change that magical “rays per pixel” ?
