Wow, I am stunned! I can only hope to someday get to that point. In the meantime, the approach I have taken is to use the Mat and Face Rooms. The Face room is a great tool when you get the hang of it. The Mat room is a bit more daunting, but worth the trouble to learn the Advanced options. The attached tut, though I cannot remember where I originally found the link to it (hope face_off doesn't hate me for linking,) is great. Though I would suggest getting the Realism kits developed by said author, this tut is where I began my trip into realism. It won't come out like FS' but you will get some really nice results.
