As of Sex Sim version 1.0h (March 2011) you can now use custom 3D pubic hair on characters instead of painting it directly onto their body texture.
The relevant lines in the XML files are:
<PubicHair>NUMBER (0 through 22)</PubicHair>
<PubicHair_Color_R>NUMBER (0 through 255)</PubicHair_Color_R>
<PubicHair_Color_G>NUMBER (0 through 255)</PubicHair_Color_G>
<PubicHair_Color_B>NUMBER (0 through 255)</PubicHair_Color_B>The PubicHair_Color values represent RGB values, which means you have over 16 million colors to choose from for the pubic hair. Each value goes in the appropriate slot, so the red value, or R goes in the <PubicHair_Color_R> slot, and so forth.
Here's a good tool for finding a color value. Just use the numbers it gives you from the Red, Green, and Blue boxes and enter them into your XML.
For the pubic hair number, use the following chart:
Please note that if you or the user don't own the Pubic Hair Styler mod, then the pubic hair you have chosen will be converted to one of four default types. A person using your character (even yourself) will ONLY see some pubic hair styles if they own the Pubic Hair Styler from the add-ons shop. See the note under the chart for the default values.* As noted above, if the user doesn't own the Pubic Hair Styler mod, then the pubic types defined in the XML will default to the following:
pubic type 0 defaults to type 0 - "none"
pubic type 1 defaults to type 1
pubic type 2 defaults to type 1
pubic type 3 defaults to type 1
pubic type 4 defaults to type 1
pubic type 5 defaults to type 1
pubic type 6 defaults to type 6
pubic type 7 defaults to type 6
pubic type 8 defaults to type 14
pubic type 9 defaults to type 14
pubic type 10 defaults to type 14
pubic type 11 defaults to type 6
pubic type 12 defaults to type 14
pubic type 13 defaults to type 14
pubic type 14 defaults to type 14
pubic type 15 defaults to type 14
pubic type 16 defaults to type 14
pubic type 17 defaults to type 14
pubic type 18 defaults to type 6
pubic type 19 defaults to type 6
pubic type 20 defaults to type 6
pubic type 21 defaults to type 6
