Recipes

NTM recipe files live under data/<namespace>/recipe/<path>.json. See the Minecraft Wiki data pack reference for vanilla recipe formats; this page covers NTM recipe fields and behavior.

Start with a bundled file of the same type from your installed mod jar. Machine recipe types add fields and interpret outputs differently.

Recipe identifiers

Name	Example	Meaning
Recipe resource ID	`hbm:custom_machine/custom_machine.paper_press`	Identifies the JSON resource and determines which file an override replaces
Recipe `type`	`hbm:custom_machine`	Selects the recipe parser and machine recipe table
Custom-machine `recipe_key`	`paperPress`	Connects custom-machine definitions to their process recipes
Recipe `name`	`custom_machine.paper_press`	Internal lookup name; defaults to the last segment of the resource path

Internal names must be unique within a recipe table. Different resource IDs can produce the same default name; a lookup by that name reaches one row.

Shared fields

The machine recipe reference gives each machine its recipe formats and examples.

Field	Meaning and default	Range
`type`	Selects the recipe format.
`name`Optional	Internal lookup name; defaults to the last segment of the recipe resource path.
`input_items`Optional	Ordered counted item inputs; defaults to an empty list.
`ingredient`	Item ID, item tag, or loader ingredient object.
`count`Optional	Items required from one stack; default 1. The item stack limit bounds a usable count.	[1, \texttt{i32::MAX}]
`components`Optional	Exact item-component values.
`predicates`Optional	Item-component predicates.
`input_fluids`Optional	Ordered fluid inputs with amount and pressure; defaults to an empty list.
`type`	Registered fluid ID.
`amount`	Amount in mB; use [1, \mathrm{tank\ capacity}] for transfers because machine code casts to int.	\texttt{i64}
`pressure`Optional	Pressure level; default 0.	\texttt{i32}
`output_items`Optional	Fixed or weighted item-output positions; defaults to an empty list.
`item ID`	Fixed output: String form for one item.
`id`	Item ID in a stack object.
`count`Optional	Stack size; default 1.	[1, 99]
`components`Optional	Item-component values.
`chance`Optional	Output chance; omit for a guaranteed output. Some machines roll each item of the stack separately.	Rounds to weight [1, 999] of 1000
`data`	Weighted choice: Stack object or an empty object for no output.
`weight`	Relative selection weight; a positive total selects an output.	[0, \texttt{i32::MAX}] each; \sum_i w_i \le \texttt{i32::MAX}
`output_fluids`Optional	Ordered fluid outputs with amount and pressure; defaults to an empty list.
`type`	Registered fluid ID.
`amount`	Amount in mB; use [1, \mathrm{tank\ capacity}] for transfers because machine code casts to int.	\texttt{i64}
`pressure`Optional	Pressure level; default 0.	\texttt{i32}
`duration`Optional	Process duration in ticks; defaults to 0.	\texttt{i32}
`power`Optional	HE demand; defaults to 0.	\texttt{i64}
`icon`Optional	Stack template displayed for the recipe; otherwise derived from the output.
`id`	Item ID.
`count`Optional	Stack size; default 1.	[1, 99]
`components`Optional	Item-component values.
`icon_from_input`Optional	Derives the display icon from the first item input when true; defaults to false.
`name_wrapper`Optional	Translation key applied around the displayed recipe name.
`custom_localization`Optional	Resolves the internal name as a translation key when true; defaults to false.
`blueprint_pools`Optional	Blueprint pools containing the recipe; a pooled recipe needs a blueprint of one of them in the machine.
`blueprint_pools_528`Optional	Replaces blueprint_pools while the enable_528 flag holds.
`auto_switch_group`Optional	Translation key grouping recipes; the machine switches to the group member whose first item input matches its first input slot.
`order`Optional	Sort position within the recipe table; lower values first, default 2147483647.	\texttt{i32}

Individual machines set operational input and output requirements and may consume only part of the shared record. Loader condition wrappers are separate from these fields.

NTM machine recipe types, hbm:crafting_shaped, hbm:crafting_shapelesssince NTM 1.0.1Applies to NTM 1.0.1, 1.0.2, 1.0.3, 1.0.4.Shown because All revisions is selected. and hbm:material_distribution reject unknown fields. Both loaders accept fabric:load_conditions and neoforge:conditions in these files.

since NTM 1.0.2Applies to NTM 1.0.2, 1.0.3, 1.0.4.Shown because All revisions is selected.

These formats also accept _kubejs_changed_marker, which KubeJS adds to recipes it creates or edits.
