Hello ladies and gentlemen and all in between! There was this new mod that was released which added variations to villagers and have gave them different overlays for differing genetics which can affect how the villager looks when breeding. I decided to create a resource pack which changes the look of them and give them a more "realistic", for a lack of a better word, look. This only alters the villagers and not the illagers.
