If you want body and not in the right side. You will need 2 textures - one with the marking,one without. Lets call the left texture "presetleft.png" and the right texture "presetright.png". Go to your preset file, open the material file and do this:
material preset_(FOLDER NUMBER)_bodyMatL
{
technique
{
pass
{
texture_unit
{
texture presetleft.png
}
}
}
}
material preset_(FOLDER NUMBER)_bodyMatR
{
technique
{
pass
{
texture_unit
{
texture presetright.png
}
}
}
}
Simple, isn't it? you only need to change names.
Just make sure you make the:
Texture(s) different names
Presets ^
I'm almost certain markings cannot be asymmetrical due to how they're applied in game. Also, I'm not sure how you would add one side and then the other without the source code. I don't think the character creator works like that.
