ice-boy, did you use a Poser plug-in to do these separate passes for you?

I experimented with this method once - more out of curiosity than anything else - but I had problems re-combining the separate layers within Photoshop. No matter what sequence I put them in, or what blending mode I used for the layers, they would not come out like the complete Poser render.

So I went out for a walk and forgot all about it!
