This essentially involves finding all of our JSON models that use craftingdead:perspective_aware as their model loader (things like hats and masks) and change them to use forge:separate-perspective. Look at SeparatePerspectiveModel to see how to define the different perspective models as it's different to our PerspectiveAwareModel.
