1.0.4 and Minecraft 26.3

NTM 1.0.4 is the first release for both Minecraft 26.2 and 26.3, on Fabric and NeoForge. Select Minecraft in the version selector to open its complete reference. The 26.3 wiki starts at NTM 1.0.4; the 26.2 wiki retains earlier releases.

Changes on both Minecraft versionsCopy Anchor Link

• world_config/worldgen.coltan_deposit controls the coltan deposit independently of scattered coltan_spawn ore. It defaults to true and also requires overworld_ores. Placement modifiers accept coltan_deposit in switches.
• world_config/mode_528 adds explosive_energistics and nether_burn, both defaulting to true. Both require the server's 528 mode.
• machine_config/rtg adds decay, default true, and scale_power, default false, which scales pellet output with remaining lifetime. 528 mode forces both on.
• machine_config/pumpjack adds oil_multiplier, gas_multiplier and drain_chance_multiplier for addon fluid reserves.
• Fluid property patches under fluid_property_patch/ change, add or remove parts of another pack's fluid-property file.
• Toxin trait entries require hazard, and protection classes are lower-case: "gas_lung" replaces "GAS_LUNG". See Toxin.
• hbm:fluid_content ingredients accept drain; crafting then takes the fluid and returns the container. Generated crafting recipes use it.
• The component predicates hbm:consume_component and hbm:unmodified_gun claim a changed component. Generated recipes consuming charged batteries or upgrading guns use them.
• Shredder outputs accept weighted lists of one item with different counts.
• Damage-type tags hbm:endermen_evade and hbm:endermen_cannot_evade decide which damage endermen teleport away from.
• The jungle dungeon generates its rooms procedurally. The old jungle/room and jungle/wall_cap pools and their room templates and processor lists are removed. Overrides of those resources no longer affect the dungeon.

Pack metadataCopy Anchor Link

Use the target format in pack.mcmeta. A 26.3-only pack can declare:

{"pack":{"description":"NTM 1.0.4 for Minecraft 26.3","min_format":[121,0],"max_format":[121,0]}}

Worldgen and loot overrides require the format changes below when moving to 26.3. The shared machine recipe fields, counted ingredients, loader-specific ingredient discriminators and NTM custom-registry paths retain their forms.

FeaturesCopy Anchor Link

Move data/<namespace>/worldgen/configured_feature/<path>.json to data/<namespace>/worldgen/feature/<path>.json. Keep the resource ID and type; move fields from config into the top-level object. A feature with no configuration is {"type":"hbm:barrel"}.

26.2:

{"type":"hbm:stratum","config":{"domain":"example:seam","state":{"Name":"hbm:stone_gneiss"},"replaceable":{"predicate_type":"minecraft:tag_match","tag":"minecraft:base_stone_overworld"},"scale":0.01,"threshold":5,"range_mult":3,"max_range":4,"y_level":30,"density":1.0}}

26.3:

{"type":"hbm:stratum","domain":"example:seam","state":"hbm:stone_gneiss","replaceable":{"predicate_type":"minecraft:tag_match","tag":"minecraft:base_stone_overworld"},"scale":0.01,"threshold":5,"range_mult":3,"max_range":4,"y_level":30,"density":1.0}

Placed features keep worldgen/placed_feature/ and their feature references. Inline feature definitions use the same flattened form. The editor schema is named feature.json for 26.3, with the new path glob.

Block statesCopy Anchor Link

26.3 block-state JSON accepts a registered block ID for its default state, or an object with id and optional properties. This affects feature states, processor markers and replacements, and fallout outcomes.

Structure templates remain binary NBT resources. Use templates from the target Minecraft build as the starting point for an override.

Loot and context providersCopy Anchor Link

On 26.3, loot predicates and item modifiers use type as their discriminator. A pool, entry or conditional modifier uses condition in place of conditions; a list of predicates is expressed with minecraft:all_of. Loot tables, pools and entries use modifier in place of functions.

26.2 pool:

{"rolls":1,"conditions":[{"condition":"minecraft:survives_explosion"}],"entries":[{"type":"minecraft:item","name":"minecraft:iron_ingot"}],"functions":[{"function":"minecraft:set_count","count":2}]}

26.3 pool:

{"rolls":1,"condition":{"type":"minecraft:all_of","terms":[{"type":"minecraft:survives_explosion"}]},"entries":[{"type":"minecraft:item","name":"minecraft:iron_ingot"}],"modifier":[{"type":"minecraft:set_count","count":2}]}

hbm:config_scaled is a context integer provider on 26.3. Its value accepts an integer, an inline context integer provider, or a provider reference. hbm:entity_enchantment_level is a context float provider. Integer fields such as rolls can read it through minecraft:from_float with its input field. NTM's hbm:random_slots fill policy remains available.

Reusable integer and float providers live at data/<namespace>/context_int_provider/<path>.json and data/<namespace>/context_float_provider/<path>.json. These are reloadable resources.

Cooking fuelCopy Anchor Link

26.3 fuel items carry minecraft:cooking_fuel, with burn_time and speed_multiplier fields referencing context providers or constants. NTM's burn-time providers use hbm:cooking/fuel/<item-path>; their files live at data/hbm/context_int_provider/cooking/fuel/<item-path>.json on both loaders. The 26.2 NeoForge furnace-fuel data map is replaced by these providers on 26.3.

For hbm:biomass, the generated provider is:

{"type":"minecraft:div","left":400,"right":{"type":"minecraft:conditional","condition":"minecraft:block/fast_cooking","on_false":"minecraft:cooking/normal_burn_time_reduction_factor","on_true":"minecraft:cooking/fast_burn_time_reduction_factor"}}

The default divisors are 1 for ordinary cooking and 2 for fast cooking. Copy this file to change biomass burn time while retaining that distinction.

Advancements and block tagsCopy Anchor Link

The 26.3 minecraft:recipe_crafted trigger uses conditions.recipes in place of conditions.recipe_id. For one recipe, use {"recipes":"hbm:nugget_am241_from_ingot"}. hbm:item_crafted retains its item predicate.

The 26.3 generated block tags include minecraft:blocks_motion, minecraft:blocks_motion_no_leaves and minecraft:washed_away_by_fluids. They declare NTM block participation in the target version's heightmap and fluid rules. Preserve relevant NTM entries when replacing these tags.
