RP-Tubes 1.2.1 — NeoForge & Fabric

RP Tubes now ships on Forge, NeoForge, and Fabric. Pick the jar that matches your Minecraft version and loader.

NeoForge

• 1.20.1, 1.20.6, 1.21.1, 1.21.11, 26.1.2, 26.2
• There is no NeoForge for 1.19.2 or earlier (the loader starts at 1.20.1).

Fabric

Also

RP-Tubes 1.3.0 (1.12.2 only)

Fixed

• Tubes now visually connect to each other and to inventories. The connection state was never computed during rendering, so every tube drew as an unconnected core. Selection boxes now match the arms too.
• Missing textures on Tin Ore and most machines. 1.12.2 requires blockstate variant keys with properties in alphabetical order (active=...,facing=...) and "normal" instead of "" — all 15 affected blockstates were rewritten.
• Alloy Furnace no longer eats its fuel and ingots. Every tile entity was being destroyed and recreated whenever its block toggled state (lit/active/redstone glow), wiping the contents. All tile entities now survive state changes.
• Recipes load again. Recipes using stone were silently dropped (1.12.2 requires an explicit data value for items with subtypes), and the Alloy Furnace recipe referenced minecraft:bricks, which is the 1.13+ name (minecraft:brick_block on 1.12.2).

New

• Copper Ore and Copper Ingot (1.12.2 only). Vanilla 1.12.2 has no copper, which made brass — and therefore every tube — uncraftable without another mod. Copper generates in the overworld and smelts to ingots.
• Worldgen config (config/rptubes.cfg): generateTinOre and generateCopperOre toggles for packs that provide their own ores. All recipes accept any ore-dictionary tin/copper (ingotTin, oreTin, ingotCopper), including entries added via CraftTweaker.

RP-Tubes 1.2.1

Fixed

• Ejector input side now connects properly. Tubes can connect to the back (input) side of the Ejector, and a chest placed directly behind it is drained as expected.
• Relay no longer drains adjacent inventories. The Relay only pushes items from its own internal buffer.

New

• 1.20.1 and 1.21.1 ports, by request. RP-Tubes is now available for Minecraft 1.7.10, 1.12.2, 1.16.5, 1.19.2, 1.20.1, 1.20.6, 1.21.1, 1.21.11, 26.1.2 and 26.2 (Forge, client + server).
