About this Mod

With this mod, all Minecraft blocks can be merged in vertical, horizontal, and diagonal combinations (Merged Blocks). This mod theoretically adds 2,000,000+ combinations.

Warning:

Since this is my first mod, some minor or major bugs are to be expected. In addition, the mod is not yet well optimized, which can cause FPS drops when a higher number of merged blocks are set.

Please note that this mod is not yet a finished version!

Known bugs

Frequently Asked Questions

Merged Blocks server crashes on startup – what to do?

Most common cause: wrong forge 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 (1.20.1). You can switch loaders with one click in the panel.

Is Merged Blocks compatible with forge?

Merged Blocks officially supports forge for Minecraft 1.20.1. The Mado dashboard automatically detects incompatible loader combinations.

Server lagging with Merged Blocks – how to optimize performance?

Recommended RAM: 4 GB (per 8 players). Use /spark profiler to check if Merged Blocks 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.
