Here are some displacement tests on an asteroid that will be present in the short. I had originally planned on sculpting something more rounded in Mudbox with all sorts of craters etc, but then I opted for the more bad-ass looking piece of rock which will eventually also have bits of ice and other jazz coming off of it.
These are all defined by mental ray displacement, and a tweaked crater procedural plugged into the material's displacement SG. After that it was just a matter of messing with the displacement amount and the texture coordinates and skew settings. The base geometry is literally just an oval.
