Fields

Field	Meaning and default	Range
`type`	Selects the `hbm:custom_machine` recipe format.
`name`Optional	Internal lookup name; defaults to the last segment of the recipe resource path.
`input_items`	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 to 2³¹−1
`components`Optional	Exact item-component values.
`predicates`Optional	Item-component predicates.
`input_fluids`	Ordered fluid inputs with amount and pressure; defaults to an empty list.
`type`	Registered fluid ID.
`amount`	Amount in mB; use 1–tank capacity for transfers because machine code casts to int.	−2⁶³ to 2⁶³−1
`pressure`Optional	Pressure level; default 0.	−2³¹ to 2³¹−1
`output_items`	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	Chance for the whole stack; omit for a guaranteed output.	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 to 2³¹−1 each; sum ≤2³¹−1
`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–tank capacity for transfers because machine code casts to int.	−2⁶³ to 2⁶³−1
`pressure`Optional	Pressure level; default 0.	−2³¹ to 2³¹−1
`duration`	Base duration in ticks; definition multipliers apply before clamping to at least 1.	−2³¹ to 2³¹−1
`power`	Base HE demand per tick; definition multipliers apply before clamping to at least 1.	−2⁶³ to 2⁶³−1
`order`Optional	Sort position within the recipe table; lower values first, default 2147483647.	−2³¹ to 2³¹−1
`pollution_amount`Optional	Pollution change: positive adds, negative removes; default 0.	finite float: about ±3.4×10³⁸
`pollution_type`Optional	Pollution kind affected by the process, when specified.
`recipe_key`	Required key linking this process to custom-machine definitions.
`radiation_amount`Optional	Radiation change: positive adds, negative removes; default 0.	finite float: about ±3.4×10³⁸
`flux`Optional	Required flux when the definition enables flux mode; default 0.	−2³¹ to 2³¹−1
`heat`Optional	Heat change: positive consumes, negative produces; default 0.	−2³¹ to 2³¹−1
