This is probably something really simple, but over the past couple of days I just can't seem to figure it out. I've looked everywhere I could think of in the source code, and on google, and have gotten nowhere. Is there possibly some way to set a shape in the model to the arm or something like that? Thanks.

Try adding a HeldItemLayer to your mob renderer.

Thank you so much, works perfectly! New problem though, the placement of the items are a bit off. Would there be a way to reposition them and possibly scale them down a bit? Here's a screenshot:

The easiest way would probably be to make your own class that extends HeldItemLayer and add translation and scaling before rendering the item.

Once again, works perfectly! Thank you very much
