Custom Entity Models (but for Fabric)

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.

Current State of this Mod

This mod is currently in ALPHA, meaning that things MAY or MAY NOT work properly! There is absolutely no guarantee that things will work as intended or at all!

Installation

Check out the CurseForge page for downloads, or build it yourself. This mod DOES require the installation of the Fabric Loader and the Fabric API.

How to use

This mod loads .jem and .jpm files from "assets/dorianpb/cem" folder in resource packs. For resource packs intended to be used with Optifine, renaming "assets/minecraft/optifine/cem" to "assets/dorianpb/cem" should work fine.

For resource pack devs

The file format for the .jem and .jpm is identical to the Optfine's (check out here, here, and here). The folder structures inside "assets/dorianpb/cem" does not matter. If 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", "assets/dorianpb/cem/ur/mom/gay/creeper.jem", etc.

Differences

• For now, only the following entities are supported (in alphabetical order):

  • Blazes
  • Cats
  • Creepers
  • Endermen
  • Piglins (including Piglin Brutes and Zombified Piglins)

• Custom shadow sizes are not supported.

• Individual part textures are not supported (you can only specify texture and texture size in the .jem file).

• Sprites are not supported.

• Mirroring textures over the 'v' axis is not supported.

• The attach option is not supported.

• Texture offsets must be specified using textureOffset, using individual uvDown, uvUp, etc. is not supported.

• Currently, all translation in custom animations is relative to the parent

  • This IS different from Optifine, so if your model wants to use super fancy custom animations, you might need to change a few values, especially *.ty values

Goals

• Implement the rest of the entities
• Maybe support custom animation translation the same way as optifine?
• attach support
