About this Mod
Sable
Sable is a library mod that adds sub-levels to Minecraft. Sub-levels are moving regions of blocks, block-entities, and entities that remain interactive while assembled. Sable contains a physics pipeline (based on the Rapier physics engine written in Rust) that allows sub-levels to move with physics and react to changes in the world.
Sable does not add any content to the survival game, or any manner of constructing sub-levels in survival.
Use /sable to assemble, modify, and query sub-levels.
⚠️ Compatibility Warning
Sable is an incredibly intrusive mod. It makes extensive use of mixins, and is prone to many compatibility issues with other mods.

Sable 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 (1.21.1). You can switch loaders with one click in the panel.
Is Sable compatible with fabric and neoforge?
Sable officially supports fabric, neoforge for Minecraft 1.21.1. The Mado dashboard automatically detects incompatible loader combinations.
Server lagging with Sable – how to optimize performance?
Recommended RAM: 4 GB (per 8 players). Use /spark profiler to check if Sable 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.
