Part 2

Here is the top mesh:

I have also added the pbr.tga so that I have skin.m.pbrmetal and am replacing the old skin.m.tbumtex.
I made a temporary mesh by joining all the parts and then doing a smart UV Project to get the right size. Do not save this mesh!

I used this to size the layout plans I used in Photoshop.

 

This I save as the new skin.tga . It goes make UVmap, export UVmap, add it to skin.tga, save, re-open Blender(so it will see the new texture) and then do the next part of the mesh.

 

This is with only two mesh done(white background not showing here).

 

This is where I am as I post this.
