The Variant Attributes Node

---

Maya Node Type → DAG Node
Maya Node Name → mvUsdVariantAttributes

---

This node is created in the process of authoring Attribute Variants on either Maya data (supported Maya shapes and transforms) and on USD data (Multiverse Compounds).

Depending on where the variants are authored (on Maya data in shape nodes or on USD data in Compounds) this node may hold different attributes, either for Variant selection or for Variant Attributes, or for both: in all cases they are added dynamically.

There are two possible node networks:

• When authored on Maya data:

  mvUsdVariantAttributes   -->   Maya Shape/Transform node
  (for variant attributes)       (for variant selection)
  

  

• When authored on USD Data in Compounds:

  mvUsdVariantAttributes   --> mvUsdVariantAttributes  -->  Compound Shape node
  (for variant attributes)     (for variant selection)
  

  

Please refer to the variant documentation

Examples for how the UI may look for:

• VariantSet:

  

• Attribute Variant Nodes:

  

• USD Attributes:
