Create Copycats Roller

by Vozarius

Create Copycats Roller, a NeoForge addon for Create, extends the Mechanical Roller so it can lay Copycats+ layers and slopes along railway tracks.

NeoForgeServer-side onlyMIT LicenseOpen source1.21.1

What it does

Precise Copycat paving runs along railway tracks, and the addon supports Layer, Half Layer and Slope Layer shapes. A Zinc Ingot selects between Layer and Half Layer automatically, and surface steps can be adjusted in 1/8-block increments. Railway beds can be raised with these steps on routes that run straight, angled or bent.

Blocks chosen in a compatible Roller filter fill Copycats, and once the filter's blocks are used up, the same blocks continue with normal Create paving on empty spaces. Tunnel Wide Fill keeps normal Create behavior. Existing player-assigned materials are never overwritten, and an operation whose full cost is unavailable is cancelled safely. Dedicated integration is needed for each compatible filter mod.

The addon is server-side only, so players join without installing it. Only the server needs the mod, which is released under the MIT License and is open source. It is published for NeoForge 1.21.1 only, with the latest file, 2.0, dated 2026-09-26.

Questions

Does Create Copycats Roller need to be installed on the client?

No. Only the server needs it, and players join without installing anything.

Which loader and game version does Create Copycats Roller support?

It is published for NeoForge only, for game version 1.21.1.

Why are some filter blocks not used by the roller?

Compatible filters need dedicated integration. Blocks in a filter without that integration are not used for Copycat fill.
