Is it possible to render a custom tile entity in the players inventory using the advanced model loader and if so, how?

 

Thanks in advance!

Yes.

 

Use an IItemRenderer - google for tutorials or see here (Item Rendering sections)

In the INVENTORY render, call the model rendering code as normal.  Fiddle with the rotation until it looks how you want.
