Entity Model Features (EMF) is a Fabric, Quilt & Forge mod that adds support for OptiFine's Custom Entity Models (CEM).
It's designed for anyone who wants to use the CEM resource pack features but also use mods such as Sodium, Continuity or ETF.

Please also install the below mods if you can, the obvious ones such as Sodium are not mentioned.
It should also go without saying EMF is NOT compatible with dorianpb's CEM and OptiFabric.
Yes.
it works :)

Q: Do all OptiFine CEM resource packs work?
A: Most packs work fine, but I'm sure there are some exceptions, report any found issues here, or on my discord.
Q: What's different between EMF and dorianpb's CEM?
A: EMF is in a complete state and has a nearly 1 to 1 parity with OptiFine CEM, EMF also does a few extra things like player animations and armor model support, with more ideas on the way :)
EMF also does things differently under the hood with little to no hardcoding of support for vanilla models. Allowing full CEM support for various modded entities.
Q: Backports?
A: Backports to 1.18 & 1.19 are planned. Backports to version 1.17 and below are not planned at this time.
