What it does

OPMatica is an unofficial addon for Litematica. It adds spray-based painting features on top of the OPSUCHT tools, letting a player spray the block they are looking at. Installation requires both Litematica and MaLiLib, and the mod is client-side only, so servers do not need it. Builds are published for Fabric and target 1.21.11.

Color variants require spray cans in the inventory, so a player should keep those cans on hand when using the paint functions, and Spraymatic is the companion mod the author recommends for that workflow. The latest Fabric file is 1.0.1-beta for 1.21.11, released on 2026-04-06 on the beta channel. The first release was published on 2026-03-23. OPMatica is not open source and is released under All rights reserved.

Key features

  1. Spray block

  3. Paint color selection

    Lets the player pick a paint color for spraying blocks.

  4. Next color cycle

How it compares

Full comparison

Litematica Chest Supplier is a Fabric client-side mod for 1.21.8, released under the GNU General Public License v3.0 only and open source, so it covers a different chest-filling task. MidiBlock is also client-side and open source under the MIT License, with a build for 1.21.11, but it works with music rather than schematic painting. Litematica Bobby Fix targets 1.21.8 under the MIT License and is not open source.

Questions

Does OPMatica need Litematica to work?

Yes. Litematica and MaLiLib are both required dependencies and must be installed alongside OPMatica.

Does a server need OPMatica installed?

No. Players add it to their own game, and a server needs no copy.

Which Minecraft version does OPMatica support?

Its builds target 1.21.11 only, and the latest Fabric file is 1.0.1-beta for that version.

Do color variants require anything extra?

Yes. Color variants require spray cans in the inventory, and Spraymatic is the companion mod the author suggests for that setup.
