Sky Multiblocks

Sky Multiblocks is a Forge 1.20.1 framework and content mod for structures that need more than a fixed block pattern. Definitions live in datapacks, reload with the server, support horizontal rotation, and can span chunk boundaries without force-loading missing chunks.

Framework Features

• JSON structure definitions under data/<namespace>/multiblocks
• Rotation-aware matching and configurable formation items
• Safe cross-chunk checks that pause while a touched chunk is unloaded
• Persistent formed-structure data and scheduled revalidation
• Immediate invalidation from tracked breakage and explosion events
• Forge formation lifecycle events for other mods
• A reusable, durable Multiblock Wrench
• Optional FTB Quests Form Multiblock task
• Optional Immersive Engineering formation tracking

Included Systems

• Survey Derrick controllers with weighted, datapack-defined survey recipes
• Stormwater Lithifier controllers with fluid, fuel, filters, pulses, and automation
• Variable-size Cementation Steelworks with ports, thermal cores, heat, scalable batches, and byproducts
• Lattice Item Ducts and item-filtering Filter Lattices
• JEI categories sourced from the live controller recipes
• Jade display integration for filtered ducts

The framework and controllers are in the JAR. Exact structures and production recipes are datapack content so a consuming pack can replace them without recompiling the mod.

Athena is required for connected Steelworks casing textures. JEI, Jade, FTB Quests, and Immersive Engineering integrations are optional.
