Issue description
I used the online skin editor from https://www.minecraftskins.com/skin-editor/ to create a skin and used it to be used with the zombie model that is used in
I have uploaded the zip file of the project with the default zombie model and a screen shot as well as the skin i was using its not using both layers since the skin is a dual layer skin
I don't know how it is supposed to look like, from the screenshot it loooks OK. But make sure you are actually using texture mapping for zombies, normal player skin mapping is not in a proper format.
