I'll tell you what little i know, You have to go to the materials room and in "Object pick the figure that you want ot change the texture on. Then on the material's click on the down arrow and it will give you a drop down menu of the different body parts of the figure that you can change the color on. The color can be changed by ckicking on the diffuse color tab whice will bring out a color chart where you can choose the color hope this helps! As far as realistic skin tones you ned to either purchase or download some free character files with "Mats" to apply to the figure...Their are some really good ones in the freestuff section just make sure their for the character that your applying them to or it won't work...Good luck!
