Here's a sample of what the materials look like when added to the trees. I'll be texturing the trees and then adding some hanging moss later on! I'll be using Zenpat's Ryse moss tutorial (http://polycount.com/discussion/130038/ryse-moss-tutorial) for a log I'm going to sculpt and paint for the ground.
@TheLazyScarecrow Thanks!! I used ZBrush for sculpting! The materials were made inside Substance Designer, and the moss was created using this tutorial; http://polycount.com/discussion/130038/ryse-moss-tutorial/p1
