Here is my level.
image?
Used cube and sphere from default primitives. 1 point light and Lightmass importance volume.
When I’m trying to build light it goes instantly to 80% and getting stuck there for 1 hour+. I think it is more than enough to calculate light for this setup even on weak PCs.
I had few successful builds using modified firstperson example, though it was inconsistent. Something like:
build light as is - fail
build with 1 more cube - fail
build with 1 more cube - fail
build with 1 cube removed - success
build with 1 more cube - fail
build with both cubes removed - success
What am I doing wrong?
