Here's a full resolution section of the second image (click to enlarge). It looks like there's either no displacement going on with the mud, or it *very* low. It may have to do with my using centimeters as the default unit of measurement in Poser. I'm not sure. I also didn't put anything in the Bump texture spot of the mud shader, but I didn't delete the node either, which may or may not be the correct thing to do. Hopefully someone can clarify this for me.
