With the new goats and deer, the much older sheep model was left looking outdated.
I have absolutely no doubt a new one (and probably more species!) are coming, or maybe someday Tenthartichect will release an outstanding pack of sheep species, but until then here is my attempt at an update.

However I made this mod for myself and out of personal preference I based the model and textures on mouflon and soay sheep, the originator species and a very primitive breed.
I have no interest in changing them to match bighorns, but my mod is open permission so anyone is free to use/edit these files and publish their changes in a mod if they want.

For the sake of compatibility this is only a shape/texture mod and doesn't touch the main sheep jsons. This means their behaviors and animation variety is unchanged but it will be very compatible with anything else that edits sheep as long as it doesn't edit their appearance.
Since I didn't want to patch/edit the behavior jsons to include any new v1.19+ animations like the goats have, their AI is noticably more basic; they are still the old sheep in everything but appearance.
