Lightmass crashes UE

Trying to build my lighting but keep getting the following error message. The datasmith plugin is loaded but I really have no idea why I’m getting this. Any help would be appreciated.



I don’t know what causes it but usually cleaning the cache in swarm agent solves the problem!

OK thanks. I will try that, as soon as I figure out how to do that…:slight_smile:

:smiley: When you start to build light in your right corner of the task bar you should see a yellow/orange(ish) s logo… double click on it and you’ll see the menu… :wink:
