This one is better it has 3D models instead of 2D. The models do not have to be based on Steve. There are protogens, avalis, dragons, eggs, and anything you can think of.

There's also Figura: https://www.curseforge.com/minecraft/mc-mods/figura

I am not an expert on these mods and I am not responsible for these decisions. I'm pretty sure that we already have something that lets you customize your player models.

The mod you sent is forge exclusive. We're a fabric modpack.

I just put the wrong link

other than ears, i don't think the pack has avatar customization

The ears mod allows for more than just ears, but I will leave this suggestion up as I am not the one who makes the final decree of whether we switch or not.

i know it does more than ears, but it is only 2d. and has to be based on regular skins, this one can do stuff like this

Which I'm aware of. But again, I am not the one who can decide this. That honor would go to @Laskyyy

ok.
