Hi , I have tried fractal terrains but I am not really satisfied with it for a series of reasons .

1 it creates a very rough surface based in fractal noise , but in no where seems to be able to create actual mountain ridges and belieavable structures
2 there is no tectonic involved but just random nouse for shapes .

I would like a generator that could take into consideration that beeing able to plan shapes and tactonics as well as crestal ridges, mountain ridges and global features ....

anything like that does exhist?
