A cloud nod is a great idea, although I am working on it now (many attempts already), still struggling. I do have a texture map already in use, along trying to use the B/W cloud with it. Noise is also needed to help make the ground (road), and I have that already in the bump. So, I guess you can see where I am going with this. I did have a png (grainy transparency image) in use, but after reading some pointers, I removed it. Still trying,
