string usd_iprimvartypename(<stage>stage, string primpath, string name)
This function returns the type name of a primvar found directly on the given primitive or inherited from primitive’s ancestor. The type name is taken from the USD value type registry, e.g., “float”, “vector3d”, “double3”, etc.
<stage>
When running in the context of a node (such as a wrangle LOP), this argument can be an integer representing the input number (starting at 0) to read the stage from. The integer is equivalent to the string form referencing a particular input, e.g., “opinput:0”.
You can also use this argument to refer to a USD file (e.g., “/path/to/file.usd”), or to another LOP node’s cooked stage using the op: as the path prefix (e.g., “op:/stage/lop_node”).
primpath
The path to the primitive.
name
Primvar name (without namespace).
Returns
The primvar type name used in the value type registry. E.g., “float”, “vector3d”, “double3”, etc.
