Okay, I've been plodding along with this software for some time now and I've kind of hit a wall with my textures. I've been using the "surface shader" for 97% of my textures but I understand that the same basic effects can be created with powerfractals with in many cases, more impressive results. I played with Volker's tutorial at one point but school kind of took over my life and in my experiements since I've had trouble figuring things out. The biggest obstacle I'm facing is the ability to limit the fractals to a certain area, say, above 100m and between 20 and 30 degree slopes. Any suggestions or is the surface shader option a better bet since I don't really want to dive into the functions?
