One of the current biggest limitations to modding is that we cannot add new assets, such as models, to the game. Thus I've resorted to using existing models.

Though, to be fair, I used the models that you normally get for henchman. So in this case it makes sense to use existing models anyway, which is why I designed it like this.

I'm not sure what you mean by "activate them via config"?

I meant that Hired Gun class isn't available for hiring, only con artist, enforcer etc. In HirableGoonsConfig.lua classes underboss lieutenant and hiredgun are disabled with "--" symbols. If u remove those symbols hiredgun class will be enabled but still doesn't have model as enforcer, for example, hiredgun will have citizen model without talents. So my question was can u add hiredgun class with a model of enforcer or conartist? Or can i do it by myself and how? Same thing with talents of hiredgun

They are disabled for the same reason you discovered, if I recall. There is something different about them that isn't working quite right. They don't seem to work same as the other code in the game. I hadn't done the appropriate digging yet to figure out what the specifics were and how I might fix it, so that's why they are commented out.
