I've come across many skins that replace those of original game models, but I don't want this to happen. I want to be able to use the skins, but on a separate model, keeping the original model intact and unchanged. I know I'll need to create a new lua file in order to use the skins, but what exactly would I need to to so that I can create a new model using the new skins without overwriting the original game model and skins?
Say for example I downloaded a Barney reskin I want to use, but I don't want to get rid of the original Barney, instead having a different Barney model with the new skin, leaving the original unaltered. What would I need to do to make this happen?
