Quick question for users: has anyone else (have had one user mention this) run into a problem with the database not being written and materials not being auto-assigned on map load?
(Apparently, the user ran into the classic UE “you can write a content directory name with a space in it, but you can never read it again”)
Each brush-mesh can be exported to FBX/replaced, yes.
No real option to do the entire map (except maybe by grouping everything in Hammer), but that’s not really adviseable anyway.
UE doesn’t like megameshes.
