The new Zombified Piglin is missing the hat layer

Comparing the old zombie pigman model to the new zombified piglin mode, it looks like the new model is missing the hat layer, used for the flesh. The old one put the skull and the flesh/scalp on different skin layers, giving the model depth. The new one has the skull start on the same layer as the scalp which makes the skull feel less real than before.
