[1.10.2] Getting the previous Model during handleItemState

[TPD]

Hello, I'm using an ItemOverrideList to modify the IModelSate of my Models according to the ItemStack and the Entity that it is held by. The problem is that the parameter "originalModel" is (as the name suggests) the original model that was loaded from the file and not the model the item was previously rendered with. This means that I have to re-instantiate the IBakedModel with a new IModelState everytime handleItemSate is called, eventhough it would really only be needed if the IModelState is no longer the same. Is there a way I can get the previous model? Maybe its possible to make the rendering system call the getOverrides() method of the NEW BakedModel (the one that was returned in handleItemState) instead of the BakedModel with which the Item was registered?

 

Edit: Am I allowed to make the changes to the original model/to its state? Or does that cause problems if there are multiple item stacks/items seen from different persepctives (gui, frame, hands etc) around?
