Really would be nice.! If you haven't looked in Shido's tool repository there is the Litmapping Tools...the folder does contain the VS projects for the texture and merge tools, so maybe you could peek at it for me and maybe guide me towards what editor I need to edit the .LIT extension. (MakeLightMapInfo.exe) it has two build options ...tree and build. Then execute. I then get a string input error using this .exe
