[1.10.2] Rendering OBJ Models For Living Entities

Hi I'm having a little trouble with using renderers (TESR , RenderLiving etc) in 1.10,  I've previously used these classes to load OBJ Models in 1.7.10 and cannot find an alternative to the AdvancedModelLoader class.

I understand how to load Obj files for blocks and items using block states and have even built something to animate them, but as for living entities / Mobs i cannot find a tutorial or solution.

I'm hoping someone could point me in the right direction.

Thanks for your time.
