I apologize, I was thinking that my previous link had offered a complete solution for this, but I forgot that I had to use a workaround. I was able to add the layers, but didn't find a way to have a variable base layer; ie, the currently applied texture or material. Seems like Snarly's EZMat should work for this, but I downloaded and installed it but can't get it to show up in Poser or do anything at all. I've been searching for a solution to this for Poser 9+ also, since I need it for my StarStorm project for Dawn.
Ran across a nice video of an alternate method to do the layers, too. I like it better because you don't need an alpha map, just your layers and a color math node. Here's the link:
