Kent may be away right now! I’m not sure who on CG Cookie is here or gone for the holidays (if any are).
Anyway, when I wanted to see the textures, I had to change the Preview number in the Multires modifier, and let it display in the viewport. I also had to have object showing as Solid.
What did you do so far, so maybe I might be able to help a little as well? 🙂
