Hi Every time i try to rebuild lights for a scene unreal crashes, does anyone have experience with this or know what i can do to stop it or even what causes it? THanks
Hi may have found the solution it appears when i updated windows it changed the TdrDelay, so used Substance advice on setting up TdrDelay, and it appears to have done the trick… ?
Lightmass crash is usually caused by one of two things, either you don’t have enough RAM or you need to clear the Swarm cache: A new, community-hosted Unreal Engine Wiki - Announcements and Releases - Unreal Engine Forums
this was definitely caused by the TdrDelay, as when i changed it the issue abated… as for RAM - do u think 32gb is enough ?
Yeah, 32GB is enough. If you run out at that amount then you should look into using dynamic lighting rather than baked lighting.
