Here's a screen capture of a fairly simple set of Material Room settings. It's the settings for the catsuit texture and bumpmap.

A MAT Pose file would contain the same information in text form, and I don't think you can avoid getting involved with the Materials Room if you want to make one.

X marks the connections between nodes. I've also marked where you put the filenames and where you can select a material. You can do a lot of fiddling with other elements, if you want to.
