currently not, sorry... i will keep it in mind if its doable for vanilla players to see still.

I was talking more about the humanoid breathing, dynamics and vapor trail

But to answer your question: it is „theoretically“ possible to use Animis for that purpose. Even if it wasn’t my first thought making it xD. I wanted animated Neki ears on a server without the neki mod, and did not want to use a hat :P

Do you mean body physics and head rotation? Thats already in plain OpenStarbound. Animis is a mod that uses the setbody/hair/emote… functions to change your directives based on playerstates or custom keybinds (if you assign a key to them).
It is intended to make working with directives and vanilla compatible characters easier.

So this is like the body animations from StarExtensions?
