Introduction to Maya - Rendering in Arnold
This course will look at the fundamentals of rendering in Arnold. We'll go through the different light types available, cameras, shaders, Arnold's render settings and finally how to split an image into render passes (AOV's), before we then reassemble it i

I'd be surprised if there was a rock making tutorial anywhere. It's not exactly "fun" persay. Biggest thing to keep in mind is organic irregularity. Once you get enough rocky formations, you can probably get good use out of them by reusing them in different orientations and such.

Small example:

Start with a cube and extrude , scale, and move faces until it looks like the rock you want. Or, use displacement mapping on a plane. Or...create a profile curve and loft a bunch of edited NURBS circles and tweak 'til your heart's content. There's also a terrain plugin over at highend3d....I forget the name offhand, but that may do the trick.

no need, just rough out the basic shape and then displace and bump map them to look like rocks. how close are you going to get to them?

alright thanks i've never bump mapped before but i see what your saying and that would probably work best.. i'm not nearly to texturing yet which gives me plenty of time to look for a bump mapping tut.

Roger Dean was the artist that did all the old "Yes" and "Asia" album covers. Do a google search and I'm sure you'll find a bunch of his artwork.
