Recipe conditions

A condition controls whether a recipe loads. For example, this one requires the expensive_mode flag:

FabricApplies to NTM 1.0.4 · Fabric.Shown because Both loaders is selected.

{
  "fabric:load_conditions": [
    {
      "type": "hbm:flag",
      "name": "expensive_mode"
    }
  ]
}

For additional conditions, see the Fabric resource-condition reference.

NeoForgeApplies to NTM 1.0.4 · NeoForge.Shown because Both loaders is selected.

{
  "neoforge:conditions": [
    {
      "type": "hbm:flag",
      "name": "expensive_mode"
    }
  ]
}

For additional conditions, see the NeoForge data-load-condition reference.

These are field fragments to include in a complete recipe.

A false condition on a same-ID override does not restore the bundled recipe. The higher-priority file has already replaced it; skipping that file can leave the recipe absent. Use a different resource ID for an additional conditional recipe, or explicitly design which replacement should exist for each configuration.

Flags

Field	Meaning
`condition` (Fabric) or `type` (NeoForge)	`hbm:flag`.
`name`	Flag name from the table below; a leading `!` negates it, as in `!expensive_mode`. Another name fails the recipe file.

Flag	True when
`enable_528`	`mode_528.enabled`
`enable_528_pressurized`	`mode_528.enabled` and `mode_528.pressurized_recipes`
`lbsm`	`lbsm.enabled` and not `mode_528.enabled`
`lbsm_simple_armor`	`lbsm` and `lbsm.simple_armor_recipes`
`lbsm_simple_tools`	`lbsm` and `lbsm.simple_tool_recipes`
`lbsm_simple_crafting`	`lbsm` and `lbsm.simple_crafting`
`lbsm_simple_chemistry`	`lbsm` and `lbsm.simple_chemistry`
`lbsm_simple_centrifuge`	`lbsm` and `lbsm.simple_centrifuge`
`lbsm_simple_medicine`	`lbsm` and `lbsm.simple_medicine`
`expensive_mode`	`expensive.enabled`

The configuration entries are in config/hbm-content.toml on NeoForge and in the content section of config/hbm.jsonc on Fabric.

Place the complete file shown for your loader at the recipe's original resource path. A pack intended for both loaders can combine the two condition fields in one file.

(Fabric)

{
  "fabric:load_conditions": [
    {
      "type": "fabric:not",
      "value": {
        "type": "fabric:true"
      }
    }
  ]
}

(NeoForge)

{
  "neoforge:conditions": [
    {
      "type": "neoforge:never"
    }
  ]
}

An item without a named shredder recipe falls back to scrap unless its components are changed; a changed item is not shredded.
