I don’t usually have problems with blotchy GI but this file is giving me fits. As you can see the bright surfaces like the walls and ceiling have a lot of dark smudges in the GI. It doesn’t seem to help if I increase the Maximum Rate in the Irradience map setting. Actually it seems to get worse. The smudges become more defined.
I am fidding with the VRay settings at the object level by increasing the Generate and Receive GI values. I did this for both the floor and ceiling. But the values are not too extreme - Generate = 1.25 and Receive = 1.5. Could this be messing me up.
My deadline is tomorrow morning, so any quick suggestions would be greatly appreciated. Thanks
the first thing I increase when I have the blotchies is my HSph subdivisions. Try 80 and see if it looks better. You could also increase your Interp samples to maybe 30 to blur the GI just a little.
Increasing the samples helped and adding an omni light - without shadows - way down low to add a little light to the ceiling in general also helped a bunch. It was sort of like the GI was light starved and I was trying to up the amount of light that wasn’t really there. Anyway, it rendered fine. Thanks for all your help.
