The more sublevels we have, the slower building lightmaps

HI.

The more sublevels we have, the slower building lightmaps goes seriously.
After rebuilding geometry completely, Swarm Agent appears.
For 100 sublevels, after seeing “Rebuilding geometry 100%” and before Swarm Agent is launched, it takes 2 hours for us.
For 200 sublevels, it takes 3 hours.
Is it normal? or is there any option to solve this?
I would appreciate for your reply.

Hello sharbong,

Yes, with this intense of a build, with that many sub levels this is expected behavior. It is also dependent on your machine’s specs.
