On Face_Off's home page (sorry no URL) he explains how to edit RealSkinShader to work with new figures such as M4 or "old" ones such as Miki 1020. You open the file and look for the comma separated list of material names and add the material names used on your given figure... mine is edited to work with everything from the Poser 4 figures through V4 including Apollo and the EF figures. You can get the material names to add by looking at the figures pull down in Material Room. The script is just a .txt file with a .py extension and you can edit it with note pad or any other text editor that saves .txt without adding formatting junk.... I use EditPad Lite which can open huge .cr2 files instantly and has good search and replace functions. I need to see if I can edit the script to give me slightly cooler under tones.
