# Custom Entity Models (but for Fabric)<\/p>\n
An implementation of custom entity models heavily based off of Optifine’s format that aims to achieve feature parity with Optifine’s custom entity models.<\/p>\n
## Current State of this Mod<\/p>\n
This mod is currently in **_ALPHA_**, meaning that things _MAY_ or _MAY NOT_ work properly! There is absolutely no
\nguarantee that things will work as intended or at all!<\/p>\n
## Installation<\/p>\n
Check out Modrinth page,
\nthe CurseForge page, or
\nbuild it yourself. This mod requires the installation of the Fabric Loader.
\nIf you want to configure this mod, the installation
\nof YACL is also required.<\/p>\n
Additionally, this resource pack or a derivative of it is required to work with optifine CEM.<\/p>\n
## How to use<\/p>\n
This mod loads .jem and .jpm files from “assets\/ ## Discord Server Link<\/p>\n Join my discord server here: https:\/\/discord.gg\/3qxFZm7Ycw<\/p>\n ## For resource pack devs<\/p>\n The file format for the .jem and .jpm is identical to the Optfine’s (check out here ## Differences<\/p>\n – Most living entites should have support, and some non-living entites might not have anmimations. – Individual part textures are not supported (you can only specify texture and texture size in the .jem file). ## Licensing<\/p>\n This project is licensed with LGPL v3.0.

\nbe used with Optifine, renaming ”
\nassets\/minecraft\/optifine\/cem” to “assets\/minecraft\/cem” should work fine. If you install the optional dependencies, this
\nisn’t necessary as there is an option within the
\nconfig to just load from optifine’s folder structure.<\/p>\n
\n, here,
\nand here). The folder structures inside “assets\/dorianpb\/cem” does not matter.
\nIf you want to assign a custom model for a creeper, you could put the file as “assets\/dorianpb\/cem\/creeper.jem”, “assets\/dorianpb\/cem\/creeper\/creeper.jem”, ”
\nassets\/dorianpb\/cem\/za\/waurdo\/creeper.jem”, etc.<\/p>\n
\n– No support for armor right now.<\/p>\n
\n– Sprites are not supported.
\n– The `attach` option is not supported.
\n– Currently, the animations do behave slightly differently than optifine’s, just enough to break some packs.<\/p>\n
\n– Make animations perfect
\n– `attach` support
\n– A better icon! This one succs<\/p>\n
\nnet.dorianpb.external for an example implementation. Make sure to use the ”
\ncem” entrypoint.<\/p>\n
\n– sp614x, for Optifine’s CEM, which this mod is based on
\n– Mojang, for actually creating Minecraft
\n– The Zombie Pigman, whose restoration is the entirety of my motivation for this project
