usd_haspayload

Since	18.0

int  usd_haspayload(<stage>stage, string primpath)

Returns true if the primitive has payload.

<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

1 if the primitive has payload, or 0 otherwise.
