Hey everyone
My scene isn’t complicated at all, and the lighting I’m trying to pull off is literally just two rectangle lights in a confined space.
These are the errors I’m getting:
<None> === Lightmass crashed: ===

This is taken directly from my message log, not sure how to fix. I’ve added a lightmass importance volume because that was an issue that popped up before, but even then it’s still failing to build lighting.
Any help will be greatly appreciated.
