string [] usd_iprimvarnames(<stage>stage, string primpath)
This function returns the primvar names that are available directly on the given primitive or are inherited from primitive’s ancestors.
<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.
Returns
String array containing the names of the primvars of the primitive and its ancestors.
Examples ¶
// Get the primvar names from the primitive and its ancestors. string primvar_names[] = usd_iprimvarnames(0, "/geo/src_sphere");
