The past weeks I have been working in some archviz projects. When I try to build my lights, I get some issues as you can see on the pics; first I thought that was something about my pc, with really bad refrigerations and sometimes too hot, but I changed my case and fans and still the same.
I get this issues everytime I try to build in high quality ( I attach a pic of my lightmass config). Also I modified the lightmass.ini to increase the NumDirectPhotonsScale=100. Still, When I use a lower quality, I did not get that much issues, but still some of the light corruptionscan be seen. I always use this configuration and never had problems.
