GregTech 6 CE

Features and Improvements

• Retire legacy integration materials and selected wood, stone, alloy, and crop materials. Clean up their associated items, blocks, fluids, recipes, resources, and translations, including leftover Big Reactors fuel rods and three obsolete construction-foam blocks. These registrations are removed, rather than merely hidden from item lists. by @SaltNya and @Tanimodori (89d279e, ff09a00, 473e03e)
• Unify the sixteen dye materials under DyeBlack through DyeWhite, migrate the uses and references of the previous color materials, and remove duplicate dye registrations. by @SaltNya (89d279e)
• Rework the fluid catalog: bind distilled water, ethanol, and olive oil to canonical fluid identities; retire duplicate concepts, unused integration fluids, and IC2 UU fluids; and update bottled items, wooden buckets, nutrition data, and recipes together. Also remove Spectral Dew and its remaining bottles, buckets, and recipe references. by @SaltNya and @Tanimodori (9cb3166, 043f780, 5be23cc)
• Introduce item-tag, fluid-tag, and material-unit unit recipe inputs. Consolidate supported smelting, extrusion, bathing, dyeing, and wood-treatment recipe families into shared rules while preserving material quantities, processing batches, and eligible physical inputs. by @SaltNya (8f672eb)
• Group eligible smelter recovery recipes for crates, arrows, and other composite items into material-unit recipes. Count only the recovered component, without treating crate wood or arrow shafts as metal, and retain the original quantities and processing times. by @SaltNya (9e3b613)
• Add JEI / EMI navigation for the physical items accepted by material-unit inputs. Link real material items to recipes displayed with unit ingredients, and share material candidates and usage indexes. by @SaltNya (8f672eb)
• Provide GT fluid display items for vanilla water and lava. In EMI, hide duplicate native entries for GT fluids that already have visible fluiditem entries while retaining fluid recipe lookup. Keep the native vanilla water and lava entries visible. by @SaltNya (07a5836, 9cb3166, 348317d)
• Update the Addon API to 1.2.0, expose material-unit and fluid-tag recipe inputs to addons and both KubeJS integrations, and update the corresponding recipe declarations and developer documentation. by @SaltNya (8f672eb)
• Optimize block-state memory usage with shared transition data, and cache inventory-model templates and geological lookup results to reduce duplicate storage and repeated work. Defer state storage to FerriteCore when it is installed to avoid conflicting optimizations. by @SaltNya (b8f72d1)
• Add workbench crafting routes for circular saw blades using plates or curved plates, and expand the accepted piston metals and redstone forms. by @SaltNya (9114eca)
• Rework waterlogging by block geometry. Support eligible small blocks, slabs, containers, and open-frame parts while removing waterlogging from full machine blocks and casting basins. Preserve water during variant replacement and direct pile placement. by @SaltNya (473e03e)
• Display predicted recipe fluid outputs in Jade as compact square icons with gray amount-and-name labels, separating them from bars for fluids actually stored in the machine. by @SaltNya (ff5aa84)

Bug Fixes

Recipes and materials

• Restore mortar and shredding recipes for retained coal-family materials, including coal, charcoal, coke, and lignite. by @SaltNya (9114eca)
• Fix paired anvil inputs so the two ingredients must occupy distinct work slots, including tag-based ingredients. A stack on only one side no longer satisfies both inputs. by @SaltNya (627e08a)
• Correct iron-family ingredients in affected cover recipes and prefer iron for their display. Keep recipes for canned food of the same type and size queryable even when flavor names differ. by @SaltNya (9114eca)

Tools, items, and world interactions

• Restore compass direction properties and model frames so the needle follows the actual heading. by @SaltNya (6946bf4)
• Drop the stored contents of loose pebbles when their supporting block is removed, and correct ordinary pebble and stone-item names. by @SaltNya (98615d8, 2553d71)

Machines, covers, and multiblocks

• Restore cover installation on formed multiblock walls, together with client selection outlines and tool-grid feedback. by @SaltNya (b6b6bb7)
• Correct combustion-chamber facing and the inset valve rendering so visuals match the functional faces. by @SaltNya (b6b6bb7)

Smelting and fluids

• Restore standard fluid-container capabilities on portable tank items while preserving fluid-tool restrictions for placed tanks. by @SaltNya (07a5836)
• Fix vanilla lava casting into obsidian products in molds and casting basins. Round complete charges up to whole mB so fractional quantities cannot prevent filling. On cooling, convert the stored material to obsidian and update its name, state, and rendering; also correct already-solidified lava in existing saves. by @SaltNya (07a5836, 11c3db6, e509acd)
• Restore mold redstone gating and CU cooling. by @SaltNya (07a5836)
• Fix static molten brass, zinc, and calcite declarations overriding generated material properties. Keep their fluid IDs and obtain temperature and luminosity from material-based generation. by @SaltNya (9cb3166)
• Correct lava's vanilla fluid binding and texture selection, prevent an extra molten.lava registration, and use the dedicated textures for Pahoehoe Lava. by @SaltNya (9cb3166)

Jade, GUIs, and rendering

• Correct large-crucible content texture tiling and fusion GUI progress, and render crucible melting-danger warnings in red. by @SaltNya (b6b6bb7)
• Supply particle textures for composite machine models to fix missing particle sprites, and use cutout rendering to restore transparent areas in leaves. by @SaltNya (473e03e)
• Add English and Chinese names for canned foods, recipe ingredient tags, and generated tags, including dye, lubricant, and water fluid tags, reducing EMI untranslated-tag warnings. by @SaltNya (2553d71, c835ecb)
• Restrict energy-unit text coloring so material names such as Aqua Regia are not mistaken for energy units. by @SaltNya (32e1e6c)
• Correct EMI lookup identifiers for wooden-bucket display recipes to avoid recipe-manager warnings, and skip redundant recipe reloads when multiblock layout data has not changed. by @SaltNya (c835ecb)

Internal Changes

• Update material compositions, ore processing, recycling phases, and wax candidates for the reduced material catalog, removing stale references and fixed-array assumptions that caused initialization failures. by @SaltNya (89d279e)
• Restructure dual-platform CI to run shared checks once, then assemble each platform and compile its test sources. Cancel superseded builds, stamp snapshot versions with their commit identifiers, and include snapshot links and commit history in the nightly release. by @Tanimodori (e96eed5)
• Organize the GT6 parity records by category, document retired materials, fluids, and related items, and require corresponding records for future changes to upstream behavior or content. by @SaltNya and @Tanimodori (771d7b5, fa9c0f9, ffe6631, 5f6ddf0, 099f9d4)
• Fix formatting-check failures in platform-specific recipe components and the coolant list, and update the mod version to 1.0.4. by @SaltNya and @Tanimodori (0f675eb, 6ffe582, c50e02d)
