Wow. I was just trying to figure out how to do this myself. I also didn't want to extract the skullcap from M4, but not because I am going to sell anything... but because it's too poly heavy and there are some weird edge flow lines around his ears.

Now I know I can use the MR in PP11... time to finally make a MOS hair that doesn't look like a plastic helmet...

If I had a nickle for ever time a woman told me to get lost, I could buy Manhattan.
