I dunno what the terminology is, if any. We need those guys who sat up late at night dreaming up "ERC" and "EMC" and "ARC" and "JCM" ad nas (which most of us just boil down to "ERC" any how). I'm pretty happy with; MAT applies textures, and does nothing but textures. (DIV or DIV-MAT or something for subdividing MAT poses?) MOR applies morphs, generally character morphs, and shouldn't include scaling or MATs. (Not to be confused with inject files...) SET changes figure in functional ways; visibility, IK, parenting, whatever turns out to be possible as we continue to experiment. Could include MAT and MOR as part of the functionality. "Character" pose applies both MAT and MOR, and may include scaling, and I don't know what to call it. The difference, as I see it, is that a SET pose is more likely to be applied to clothing, or a house, and does things like remove all the buttons or draw the blinds. The "Character" pose maintains the essential geometry and heirachy and applies all those little touches (materials, morphs, scaling, joint param adjustments) that make a character. Um. This all went a little afield of original topic. Sorry.
