About this Mod
🎨 Spraymatic
For the best experience with Spraymatic, make sure to have all color variants of the required spray cans in your inventory.
Ever built a large map, pixel art, or colorful megabuild? The Spraymatic automatically reads your loaded Litematica schematic and colors the block wherever you point, whether it's wool, concrete, terracotta, or glass. No more manually swapping colors block by block.
🛒 EasyMarket
- The EasyMarket detects which block is needed next according to your schematic and checks if you have it in your inventory, if not it will open the OPSUCHT Markt if the Item is available to buy, keeping your building flow smooth and uninterrupted.

OPMatica server crashes on startup – what to do?
Most common cause: wrong fabric version or insufficient RAM. Check the server log (latest.log) for "OutOfMemoryError" or "Mixin" errors. With Mado Hosting: ensure at least 3 GB RAM is allocated and the loader matches the mod version (1.21.11). You can switch loaders with one click in the panel.
Is OPMatica compatible with fabric?
OPMatica officially supports fabric for Minecraft 1.21.11. The Mado dashboard automatically detects incompatible loader combinations.
Server lagging with OPMatica – how to optimize performance?
Recommended RAM: 4 GB (per 8 players). Use /spark profiler to check if OPMatica consumes the most tick time. Common fixes: reduce server view-distance to 8-10, install "performant" or "starlight" as supplementary mods on Forge. With Mado Hosting, your server runs on NVMe SSDs with dedicated CPU cores for minimal latency.
