I can save it as a materuial collection; that's no problem. The problem I'm having is saving the transmap as a material collection, without saving the skin as part of that. If I make a material collection with the transmap applied, it'll save the transmap, but it'll also save the skin texture. If I reapply the material collection to another character, the leg will disappear, but the skin will change, too. I want to be able to make the leg disappear without changing the skin of the character. Say I have a light-skinned character, and a dark-skinned character, and I want to be able to apply the material collection with the transmap to either one without changing the skin of either character.
