Hi Ptrego, how deep do you want to go? 

How are you at applying nodes to proper PoserSurface channels within the materials room? --that will be your first step.

If you are familiar with that, the next step in its simpliest form is import a 1024X1024 picture with a design in it, then render.

If you want to place stuff  say a logo, neck trim, zippers, etc,  in exact places then we will go with UVmapper.

If you don't know how to work with UVmappers:  we can start there:  Jan
