Java mod listed for Minecraft 1.20–1.21. Downloads from the MC Java Mods app on Android.
I don't know my version or loader
Open the Minecraft launcher and look at the profile you play on — it names both, like fabric-loader-1.21.4. The version also shows in the bottom-right corner of the game's main menu.
No loader in the profile name? Then it's plain Minecraft, and these mods won't run — you need Fabric or NeoForge installed first.
This mod is a simple library/utility mod for creating multipart blocks, rendering, interaction and all things you would expect from a multipart API.
Requires 
Hammer Lib.
Features:
- Multiple Parts: Allows placing multiple parts within a single block.
- Custom Renderers: Provides custom renderers to display the multipart block visually.
- Models: Supports defining custom models for each part of the multipart block.
- Interaction: Allows interaction with individual parts of the block.
- Hitbox Overrides: Enables overriding hitboxes for each part.
- Tickers: Supports adding tickers to control behavior and updates of the multipart block.
