Alehouse CobbleGen 🍺
The ultimate cobblestone generation solution for Fabric 1.21+.
Designed with performance and aesthetics in mind, this mod adds 9 tiers of cobblestone generators. Whether you are playing Skyblock or building a massive factory, Alehouse CobbleGen provides the resources you need without killing your TPS.
Key Features
- Extreme Optimization: Unlike other mods, this generator calculates drops internally. It pushes items directly into the storage above it. No entities dropped on the ground = No Lag.
- Smart Buffer System: If the inventory above is full, the generator stores cobblestone in an internal buffer (4x generation rate).
- Crash Protection: Breaking a generator with a full buffer does NOT drop thousands of items. It safely clears the buffer to prevent server crashes and item spam.
- 3D Models: Each tier has a unique, custom-made 3D model. No flat textures!
- Vanilla-friendly: Fits perfectly into the vanilla aesthetic while offering powerful automation tools.
