I'm having a rather annoying problem im hoping to get assistance on.
Here is where I am at for you to better understand me and what my problem is.

Im editing a base model named weequay.
I opened it in ModView and looked at the surface tree on the left.
I scrolled down to see if there were any unused hair surfaces for the Ghoul2.

I saw three things that came to my liking.

head_r_hairback_off
head_r_hairshoulder_off
head_l_hairshoulder_off

I turned thease on by right clicking them in the tree... wrote a model.mvs...opened the model.mvs to see this:

loadmodel 
{ 
   name      "model" 
   modelfile   "models/players/weequay/model.glm" 
   oldskinfile   "default" 
   surfaces_on 
   { 
      name0   "head_r_hairback_off" 
      name1   "head_r_hairshoulder_off" 
      name2   "head_l_hairshoulder_off" 
   } 

}

So i looked at the model_default.skin and saw that they were already inthere with the correct paths.

My problem: i know how to remove surfaces by using a .skin file, But i don't know how to add them. I'm assuming that i would have to rename the Surfaces in a modeling program.

so again, im trying to Add:
"head_r_hairback_off"
"head_r_hairshoulder_off"
"head_l_hairshoulder_off"

Any help from anyone with a true understanding would be wonderful.
