Tried all of those things and it still crashes on build.
The previous maps I built were just single land mass using original terrain textures to test some skins that I had made for a fw190d9.
As far as exporting the terrain tiles to edit, i don't know how to do that using the terrain editor, for I can't find a "save texture" feature for terrain, as there is one for the objects. I found the 20 stock terrain tiles on the bbs and edited those and placed them into the texsrc folder. These are labled "terr000, terr0001, and so on" Again all these files are 256x256 all 8bit, all labled in small caps.
Only difference between the files is that some are at a 96dpi resoulution and some are at 71dpi.
At a loss here....
