JsonEM -Mult
JsonEM -Mult is a library for exporting and editing Json Entity Models, a format used by a Fabric mod for Minecraft 1.20.1 that this build migrates to newer versions.
What it does
The mod lets a user create a new JsonEM Java Entity Model from the File menu, edit it, and save it to a file. Models can be exported through File, then Export JsonEM Java Entity Model, so the saved file can be used in later work. Fabric API is required, and the mod is published for Fabric, Forge, NeoForge and Quilt across two release versions, 1.20.1 and 1.21.1.
Resource pack and modpack makers are the intended users. Dumping the entity models of the game, both vanilla and modded, produces reference files that can be edited and added to a pack as entity model JSON files in the dumped format. The process is run in steps, and the author text includes an example of how to use the exported models in a resource pack.
Only the player's game needs it, and servers run without it. The code is open source under the MIT License, and the source code and issue tracker are public.

Who it’s for: The mod suits resource pack and modpack makers who want to edit entity models. Players who only install packs made with it need nothing, because the mod is client-side only.
