A new rendering tutorial. This is a first go at what will be a much more complete tutorial for rendering displacements out of Zbrush. I just wanted to get this out there for those who will find it helpful now. The key concept here is that your model should consist of the same number of polys at render time as it does in Zbrush to get the level of detail you desire.
