This is a tutorial aimed at both new and perhaps more advanced users which deals with the relationship between UV mapping and cylindrical projection mapping. Specifically, it deals with two things; how to map the caps separately from the cylinder; and how to create distortion free UV's for the body, meaning how to maintain the correct aspect ratio of the cylinder 3D geometry to the UV space geometry. In many ways this is geared towards users newer to UV mapping so there's a lot of explanation about the UV space. This tutorial is done entirely in Design3D but does use Wings3D to help demonstrate a few parts of the tutorial (it's not necessary to know Wings3D for this tutorial).
