How to reskin a specific citizen model

How do you make it so a skin works for only one citizen model? By this, I mean that I only want to make a skin for male_07, not all of the citizens.

I don’t think it’s possible for replacements. If you want separate ragdolls you should use hexing, it makes a new model for the texture so it won’t replace it.

Think you can download a program on garrysmod.org there can do it.

I think I might do that. Anyone know a tutorial for it?
