I have looked, but cannot find a simple answer, at least I think its simple, have 2 terrain files from GM and 2 aerial images from GM one of an area 10*10kms and 1@ 1*1km at much higher resolution, and it is inside the larger area, I can combine the terrains fine, but struggling with the textures, so the higher rez texture shows up over the top of the lower rez one, any pointers appreciated
cheers
