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.



  • 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.




  • You can use this mod in your modpack.
  • Yes, you are allowed to build a mod that requires HammerMultipart, but do not embed it!

  • You are not allowed to include this (or any other mods of the DragonForge team) in your own mod. Building add-ons, however, is allowed, but a friendly PM would be good.
