I'm in the newest version on 1.21.3, and when i booted it up, the second layer of my skin was absolutely freaking out. the textures are pushed outwards and downwards on the arms and legs respectively, and the head texture is moving independently of the head. I'm not quite sure what the issue could be other than the new version, but that shouldn't have an affect on this

Can also confirm this is broken in 1.21.3 to 1.21.1 i also have the latest version of this mod and EMF and ETF

Can confirm. Something appears to have broken with either the pack or one of the mods with the move to 1.21.2:

Can confirm the same, visual error applies to skins that aren't made for the pack as well.

I don't know if that's the issue, because I have the eyes still working on my skin, along with all the animations, just the skins 2nd layer is
messed up

same (version 1.21.3 ETF and EMF latest version)
