3D Minecraft Skins are rendered wrong

[SpraxDev]

Describe the bug
Some skin parts are rendered wrong in the 3D version as they are getting mirrored.

To Reproduce
Take a look at the face. The front of the body is falsely mirrored too but I can't find an example for that at the moment. 2D Version is how it is supposed to be looking.

3D Version (src-1, src-2):

2D Version (src-1, src-2):

Original (src-1, src-2):
