I actually looked around a bit for some converter programs. It seems there is no direct way to convert .map files from id Tech 3 to UE4 map files. Is this true?
Seems most people import maps to unreal by importing to some modeling program, then export to .fbx or something. Was this the way you did it?
Heck i don't even know what the map file format in UE4 is called. Seems to be inside some .asset, and stored among other things.
If i could figure out a way to get to proper documentation i would be eager to write a converter though. Seems many people keep asking for such things, also from other games.
