*** UPDATE*** I'm having another go at trying to add some new units to my game prior to the expansion pack coming out. I figured out copying units from the base game, but I cannot figure out how to use the artdef from other sources... I'm not sure if I have the folders setup incorrectly... But for example, I made the MOAR units a dependency, and copied the artdef for the Equite unit, but it still doesn't show up in my game. What am I missing? Is anyone able to offer any assistance? Thanks! Spoiler Original Post : I had a simple little mod that I enjoyed in Civ 5 - I had added some extra naval units by duplicating existing units and tweaking their stats. In the previous game I just altered a framework for changing a unit that someone posted on here. Can anyone give me a framework or assistance in doing the same thing in Civ 6? I'm looking to change the combat stats / cost, change the melee naval units into naval ranged units, duplicate the battleship and tweak it to become a battlecruiser, things like that. Any help would be greatly appreciated.
