Hi Bloodsong, Pleased that you've managed to work out our somewhat convoluted technique for getting pictures to map onto terrains:) We just did it by trial and error basically... I don't know WHY it works like that! But it certainly sounds as though it should be possible to scale the terrains numerically doing it your way; we didn't really go any further because once we'd got a fractal mapped onto the terrain all we had to do was position the camera.
