Is your feature request related to a problem? Please describe.
Well I wanted to use Fresh Animations and other resource pack that uses Custom Entity Model

Describe the solution you'd like
A clear and concise description of what you want to happen.

Describe alternatives you've considered
Optifine but I want to use Rubidium and Oculus since it uses less CPU power and less Stutter

Additional context
built in would be nice but it can be a seperate mod too
