No, I don't mean bumb maps. I mean if there is any function in Mayaor plugin that helps you making a mountain easier. I have seen somewhere(can't remember where) that you can make the mountain with terragen and export the mesh into maya. With bumb maps you actually simulate bumbs, but what I need here is actual model of mountains.
I hope I said it clear. Tnx anyway for trying to help me

p.s.: oh, and with that alpha map I ment if there is a way to generate a model (and not bumb on a singel plain) using that alpha map. So at the end of process, you have the model of mountain, not only a singel plane (where the results are only seen when rendered).
