usd_isarrayprimvar

Since	18.0

int  usd_isarrayprimvar(<stage>stage, string primpath, string name)

This function checks whether the primvar is an array, if it’s found directly on the given primitive.

<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

1 if the primvar exists and is an array, or 0 otherwise.

// Check if primvar "some_primvar" is an array.
