assmod player models

is there a way to change the models that assmod gives the players depending on what rank they are.

Yes.
Go into C:\srcds\orangebox/garrysmod/addons/assmod/lua/plugins
Or something like that.

Find either ass_grouping.lua (if you have it) or ass_playermodel.lua (or something like that) and edit either one of them with notepad.

If you’re using ass_grouping.lua, remove ass_playermodel.lua.

Good luck.
