Can anyone point me in the direction of some simple step by step instructions for generating a new skin texture for a poser figure. 

Let me explain. 

I'm not particularly looking to do this "for real", I'm not enough of an artist to actually do a good job with a real skin texture. What I want to do is understand the mechanics of the process.

I want to be able to take an .obj file (anything, not necesserily a humanoid), flatten the x,y,z 3D object to a two dimensional map, import it into a photo editing app, make a texture and apply it to the object in Poser. Ideally I would like to start with something simple - like a cube and work my way up to a humanoid.

I understand the UVMapper application, which i have, can create a 2D image and I have used it on a poser figure (V4) to create a 2D map. Great. Unfortunately the map (which looks wholly believable) looks nothing like the textures that are actually used to clothe her in her skin. To start with, UVMapper creates one map, whereas V4 has several JPG files which go to make her appearance.

Are there any simple (for i am a simple soul) tutorials around that anyone knows of.

Thanks in advance.
