Is your feature request related to a problem? Please describe.
I'm having clipping issues with a cosmetic mod called "Advanced Skin Customization" (I know it's bad to post links but here's a link to the mod https://www.curseforge.com/minecraft/mc-mods/advanced-skin-customization?page=2) and my characters cosmetics go through my character's body.

Describe the solution you'd like
Add support by setting the cosmetics to follow the correct bones if it's possible

Additional context
I'm running the mod on 1.12 but other people may want it for all versions

nevermind I saw in the discord server in the faq
Q: Can you provide compatibility/special animations with/for x mod?
A: No, but the devs of that mod will be able to use the API for animations.
