GregTech 6 NeoForge

Added

• Glow ink sac juicing: Glow ink sacs can be processed in the juicer to yield black ink and glowstone dust.

Changed

• Unified mud: GregTech diggable mud is now unified with vanilla minecraft:mud. All GregTech processing (sifting, drying, furnace recipes, tool interactions) applies to vanilla mud, and blocks in existing worlds are migrated automatically.
• Lighters in crafting: Lighters used in crafting recipes consume a single charge instead of being destroyed.
• Lighting candles: GregTech lighters can light vanilla candles.
• More Red integration: More Red is integrated into GregTech progression — rotational power connects directly via axles, redundant workbenches are removed, Red Alloy is unified, and logic gates use GT circuit boards.

Fixed

• Inventories and machines survive modpack changes: Stored items, machines, covers, canvas paintings, and stuck arrows are now identified by registry names instead of internal numeric IDs. Adding or rearranging mods in a modpack no longer scrambles items or machine identities.
• Server crash during cauldron ore washing: Washing the last unit of ore in a cauldron no longer crashes the server or corrupts the world save.
• Hotbar auto-refill restored: When a tool breaks in hand, it is automatically replenished from the inventory.
• River water repair: River water actively takes over touching ordinary water and heals gaps in the riverbed naturally.
• Dungeon mechanics restored: Dungeon mob-farm water flows properly instead of sitting as a still block, and piston doors are properly closed and operable by their crank.
• Lava spills drain away: Crucible burn-throughs and spillage from faucets, molds, or smelteries create temporary flowing lava that drains away instead of leaving permanent lava sources.
• Block face shading under modern renderers: Vertex ordering on block faces, fluid surfaces, and flat item icons now follows engine canon, resolving upside-down shade maps under external chunk renderers like Sodium.
• Network version mismatch refused: The network handshake now verifies the exact mod version, preventing clients on different builds from joining and experiencing silent desyncs.
• Recipe viewer material consistency: Recipe cards for material families consistently match the input and output material on the same card.
