(Fabric 1.21.5) Skin breaks if it has 3d details or overlay pixels

[Nangt3c]

If the player skin has any 3d layer details, it detaches from the head and moves separately.

Same issue, same version, while using the sitting plus mod.

This line of code

this.hat.copyFrom(this.head);

in minecraft/common/src/main/java/dev/kosmx/playerAnim/mixin/PlayerModelMixin.java causes the bug.

It is no need anymore for Minecraft upper than 1.21.2 as Mojang changes the model structure of Player.

You can just comment or remove this line to fix this bug

@Etern-34520 we highly recommend you just use PAL instead:

It's even mentioned in the readme as the successor to this mod

Though if there are a lot of people on 1.21.5 of all versions then I might publish a fix for this
