XMLSpy, the texturing is rubbish on that, although I hate pimping my own stuff (especially as I don't get a single penny for a sale of it) Terrain shader from idigicon textures much better as it takes into account, slope and various heights and then alpha blends from one into another making very smooth and subtle textures, this blend range is totally definable, not ones like texgen that has harsh edges from the change from one texture to another.
