Well, did some testing. and i hope somebody can say why interface.exe is crashing.
Curious if High Fidelity is having enough memory for heightfield maps.
Tried the following sizes today
The all crash my interface.exe on windows 7 - 64bit
Only 2048x2048 and smaller seems to work fine. Problem with that tiny size is that you cover only a very small area. And working with small tiles i cpould do, if the make importing it more easy. I dont do it because aligning it seems a crime. As example how do yopu know where you first map ends. precies at the number ?
