ok i just decompiled a mdl and edited it in photoshop, how do i re-compile it so i can use it? i am using milkshape, and please dont just direct me to danzas thread on this, i already read it and i dont really understand, can anyone give me some help?

You recompile using a compiler. Duh.

Studiomdl is the compiler. Just run it and feed it the name of your qc as a paramter. I think that's all.
