So you need to open the material file (The notepad) and edit the names of the body part.
For the file in the notepad, it will say "preset_3body" twice. Change one to "preset_3bodyR" and the other to "preset_3bodyL"
When you save the preset files that you colored on, now change the name of the file to match each of those names. That should change everything.
You just need to make sure that everything shows up- if not, the coding is wrong or the file names are wrong.
