Just curious if there is a way to use an RE pass while rendering to determine where I should focus my Region Render areas? It seems the best indicator currently is the beauty pass, thought the Cinfo_SamplingFocus would provide info for that purpose.
On quick renders, I'll use the intel CPU AI Denioser, then region render the noisey areas. I decent work around is to 'Save CXR', see the noisey areas, then 'Resume' and focus the Rengion render on those areas.
