Hi!

I'm into rendering landscapes right now, and i've been fairly successfull.
The one thing i can't get my head around is how i control textures
depending on how steep the slope (on a mountain side for example) is. I
found something called slope_map, but thats not what i'm looking for.

I also read somwhere that one can use the trace command, but it seems kind
of hard (i'm not that good at math).

The thing i wan't to do is to control, for example, grass and stone textures
depending on steepness of a mountainside. Where the surface is relativley
plain, i want to have a grass texture, where it's steep i wan't to have a
stone texture.
