Hello,
I have a big archviz project on which the light built was okay now that i have added a few new meshes and textures it just won’t build. I check around and everything sugguested i am running out of memory so i reduce all of my lightmaps by 50% and it still doesn’t work which is strange since i didn’t add so much new things into the scene.
I am using GPU lightmass in 4.25. I have 2x gtx 1080ti and 32gb ram. After i press build it starts working on radiosity pass after that is just closes no warrnings or errors. Here are my Swarm log notes.
