I've heard references to a shader that places canyons all over a surface - does such a thing really exist or am I going to have to make my own?
Thanks for any help you can give me.
Maybe you're referring to my script?

Make sure you read the instructions ;)
Thanks a bunch man!
Edit: hmm.. that's not quite what I needed, i'll play around and see if I can create a shader that randomly places craters everywhere.
