A tutorial on how to use custom model data in the Minecraft 1.21.4 update.

Example resource pack: https://ewanhowell.com/resourcepacks/...

Custom model data is kinda pointless in 1.21.4 to be honest, you can just set the item model directly on the item using components, so you should probably do that instead ¯\_(ツ)_/¯
