FTB Ultimine Copycat Compat

FTB Copycat Compat is a lightweight NeoForge mod that brings FTB Ultimine compatibility to Copycat blocks from Create and Copycats+.

Features

• Chain Material Application: Hold the Ultimine key and right-click a copycat block with a BlockItem (e.g., a block of Iron, Andesite, etc.) to apply that material to all adjacent copycat blocks with the same shape.
• Chain Material Removal: Hold the Ultimine key and right-click a copycat block with a Wrench to remove the material from all adjacent copycat blocks with the same shape and material.
• Smart Matching: Only selects copycat blocks of the same type (shape) and same material, preventing accidental mismatches.
• Compatible with Create & Copycats+: Works with vanilla Create copycat blocks and extends support to Copycats+ blocks via reflection.

How to Use

1. Install FTB Ultimine (required), Create (required), and optionally Copycats+.
2. Hold the FTB Ultimine key (default: ~ / backtick).
3. Right-click any copycat block with a BlockItem to set material, or with a Wrench to remove material.
4. The action will chain-apply to all adjacent matching copycat blocks.

Dependencies

• Required: NeoForge 21.1.224+, Minecraft 1.21.1, Create 6.0.10+, FTB Ultimine 2101.1.15+
• Optional: Copycats+ 3.0.4+

Compatibility

• Fully compatible with Aero Reformation — when both mods are loaded, Aero Reformation handles the registration.
• Client-side only features? No, logic runs on server. Single-player works fine.

Tips:   Due to interaction issues between chain mining and Create's Wrench, using the Wrench to directly break copycat blocks may consume the block — this is not an issue caused by us.

Installing the Create: Ultimate mod can resolve this issue.
