For me, the best way I could think of to do the eyebrow change would be the same way some people did the eye color change in the beginning. The map would be totally blank except for the iris. why couldn't you just do the same thing with the eyebrows since they would only load that section of the map anyway. That would pretty much eliminate the map file size issue. And if you're going to use the upper brow maps, then I would suggest making a smooth, browless area on the face itself to avoid that heavy overdone look. As for the MAT file thing, it's much faster and easier for me to just go into the material editor and apply the map to the specific area. Since I installed win98 on this thing it takes me forever to scroll down that stupid, idiotic ONE LOUSY FREAKING COLUMN. I miss my old three column wide, click on the one you want in an instant drop down that I had with 95. sigh
