The reason for the swirlys is to show the impressions left by a worm when walking through the dusty dirt (other worms have been here before); similar to a snakes' path, but you're right, it is little distracting and tiled looking. I could alter that in post-production, but that doesn't help me learn how to do this "the 3D way". I'm for sure working on that. Please don't hesitate with constructive criticisms. It's why I assume we are all here; to learn from one another. I have a long way to go in the shader department and need work in other areas as well. I'm just happy to finally be producing in Carrara and get more excited every day when I see how easy some pretty cool effects are and the amazing stuff you guys are doing with it.
