3D Rig for 2nd layer skin

[Xantenex 0]

The title kinda says it all. I'm looking for a rig that gives me the 3d effect for my models 2nd layer.

I found this version: 

 

 

But the 2nd layer is way too thick. Is there someone who could either edit this on to have a slimmer 2nd layer? Or maybe there's one out there that I can't find.

Thank you!

Update: I can add the the rig to modelbench to change the thickness of the 2nd layer from 1 to .5. But when I load the model back in to mine-imator, the textures are all messed up
