# hbm:duct_fluid

Records the selected fluid of a template's fluid ducts.

Give a fluid-duct block's template entry an `nbt` compound containing `hbm_duct_fluid: "minecraft:water"`, or another registered fluid ID. This processor records that selection in the receiving chunk and removes the template entry's NBT before placement. The marker must belong to a fluid-duct block.
