Lightmass Crashing

Hey All,

I’m getting render errors every time I try to build lighting. I have rendered before in this scene, and it was fine.

This is the error:

I am also getting this same crash since updating to 4.18

FYI, I was able to make this stop by clearing the cache in lightmass on all the swarm machines we were using. Not sure if that will help you or not. I also deleted a number of lightmass importance volumes and remade them, not totally sure which fixed the crash (if either).

Yup - Clearing the cache in the Swarm Agent worked for me.
Thanks for finding that one out :slight_smile:
