Well, I’m testing right now famous sponza scene. Getting weird things - can’t get LC\irrmap to compute in render region I chose. It gets computed in whole cameras safe frame region…
So try set a region render, set the region and press render - LC\irrmap will compute for cameras safe frame region only.
Only for this scene and only for this particular VRayPhys cam. When I just clone this cam and render through new one - all’s just fine.
for some reason it seems to be picking up the region size from another cam.. simple fix.. change to cam1 then back to vraycam.. and do a region render you will see now the region size is that of the safe frame.. resize it and it will follow the region properly.
