On the MAT pose files I cheated bigtime, I just edited a MAT file I got from the Daz textures. Simple and fast... it's pretty obvious once you look at a small one :) I know what you mean about the maps - thats cool - there is room for "lo-rez" textures so to speak :) As for the PNG - I just hate the loss of jpg's - but with a high quality setting (9 out of 10) they compress OK and have a limited number of errors :)
