About this Mod

Automatically generate missing item asset files for mods to ensure compatibility with Minecraft 1.21.4+

Starting from Minecraft 1.21.4, mods are required to include the assets/(modid)/items folder with specific item asset JSON files. However, many existing mods only have assets/(modid)/models/item/ assets and don't provide the new required files, causing compatibility issues.

This mod automatically generates and loads the necessary items assets at runtime, allowing older mods to work without manual asset updates.

Ideal for mod developers or pack creators who want to maintain compatibility with 1.21.4+ without rewriting assets.
