heyas; you can rotate the terrain in the view, to look at it from a different angle, but you can't rotate like the 'image' that makes up the terrain. for example, on the fx tab, there's these cracks -- they all go vertical to the picture. if you rotate the terrain to look at it sideways, the cracks still go the same direction relative to the terrain they always have. ie: you can't get them to go at right angles to the way they always go. (or 45 degrees or anything.) or, if you do dunes, you know they go in one direction. no matter which way you turn the landscape, all the dunes go along the same lines. and/or when you hit the wind erosion -- the wind always comes from the left. you can't blow wind from the right.
