The following describes how I setup the UV's for my model in order to paint the textures.

Step 7
: Now you need to transfer the UV's from your duplicate back onto your original model. There are a couple different ways you can do this, and all work just as well (as far as I can tell). One way is to use the Polygons>Transfer>Options command and select UV Sets only. Another way is to select each face and choose the Edit Polygons>Clipboard Actions>Copy>Options (can also be found in the UV Texture Editor under Polygons>CopyUV/PasteUV) and select the UV attribute only, and do that for every face of the duplicate and paste it onto the matching face from the original. I wrote a quick script that does this automated, and you can grab it from here.

Step 8:
Here are my textures in progress from Photoshop. I'm still working on them, but they look ok for now. No specular map yet either, but on the right you can see my colour and bump passes with the UV's layed on top.
