I have created an arm with common surfaces on 'upper arm, lower arm' etc.
Each part is a separate layer with separate UV map.
I have taken into 3D Coat to surface and exported out images.
In LW I only have the one set of surfaces for the whole arm, but different UV maps for each section.
Is there a way to combine the multiple maps in the Node editor to the one surface (if that makes sense).
In retrospect I should have either created one UV map or multiple surfaces, but I'm being lazy.
