@LonewandererD - I wish I had Photoshop and knew how to use it. If I did I'd have written this tutorial for PS as well. However, aside from the kind cloud patterns that I am using to generate the height map, I'm pretty sure that the rest of the steps in this tutorial are easily translatable into PS, and of course the instructions on Wilbur will be the same regardless.

@Gidde, AMichael and Boundary Layer - Thanks for posting. Please feel free to let me know if you come across any problem areas in the Tutorial (e.g. areas lacking in clarity).

Cheers,
