materialRequirementHashes property
The list of hash identifiers for material requirement sets: materials that are required for the node to be activated. See DestinyMaterialRequirementSetDefinition for more information about material requirements. In this case, only a single DestinyMaterialRequirementSetDefinition will be chosen from this list, and we won't know which one will be chosen until an instance of the item is created.
