So I'm using Falkren's Hellenic League Unit Pack, and as always, I am modifying its units so that they look more like the way I want. I was changing the helmet type of a unit, and when I went on the game to see how it was, I realized that, on the files, helmets are organized in groups and not in individual helmets. The "attic" helmet group for example includes 4 different helmet models and the "thracian" helmet group includes 3. The problem is that I want to remove specific helmet models that I don't like from each of those groups, and I have no idea how. Can someone give me a hand? I'm a noob at modding.
