Hey guys!
I did a fresh install of Unreal engine, version 4.23 tried to import a scene from 3ds max using my datasmith exporter.
Nothing really complicated. I import everything in unreal editor, try to build lighting (all default values i change nothing) and it doesnt even start the swarm, it brings the first inital window for 3 seconds and then closes it and does nothing.
If i do exactly the same on 4.22 it works.
Any suggestions on where to look for the problem?
