I've downloaded everything right and MCA is working fine, it prompts me in the start of my world with all the customizations and whatnot. I'm just wondering if the mod instantly replaces the vanilla minecraft villagers? Because in my server, we live close by a village and I wanted to add a fun npc mod.

When I entered the world, yes I do get prompted with the char creation and even received the book, but the villagers are still the same and not the MCA human models. But when I make a new world, the villagers are all MCA models now. Do I have to slaughter all of the villagers and then slowly replace them? I'm not sure haha

Oh I just found the convert all vanilla villagers command, it works aaaaa
