farang, There's nothing in the manual on MATs because they were discovered by us users (can't remember who) after Poser was released. There are several ways to make MATs, the easiest being to get Mat Pose Edit from Freestuff. The way I do it is to save the cr2 and edit out the unnecessary lines in cr2Edit, but that might be a hassle for most users. Or you can do it manually in Notepad. What you need in a MAT pose depends on the type you're making. The different types are MAT, which only affects textures. MOR which affects the morphs, and placement files, (which I call POS), which affects the trans dials, scaling and rotation, (in other words, size and position). Or, of course, you can combine them all in one. I can't remember if Mat Edit Pose does them all. I have it, but only used it once. Anyway, for textures, it's probably the easiest way to do them. mac
