I think I have found the answer to my question, which I have asked more than once: "How to make a deer hornless, a female or a fallow deer." You need to go to the Computer folder ProgrammFiles - Tale of Tales - The Endless Forest 3 - Data - Assets - Characters - Deer and find Deer1antlersLoD.cgr and move it to any other folder (I advise you to create a new one and move the Deer1antlersLoD.cgr file there), go into the game and see, we did it, a deer without horns!
I hope I helped you.
