About this Mod

What does this mod add?

This mod allows you to register fully custom items via a simple config file at will.

This is a perfect choice for all of you datapack creators out there, who want to include a completely custom item(s).

Just head to the mod's config, and add an item into the array. The game will need a relaunch to make your changes actually take effect, but that's minecraft's limitations.

For now, you're required to know the basic principles of the JSON format, but soon there is going to be a nice UI for adding your items, so stay tuned for any updates!

Please note, that the registered items will have no model, texture, or be assigned to any language file. You're required to have some resourcepack knowledge to assign them.
