int usd_isactive(<stage>stage, string primpath)
This function checks whether the given primitive is active.
<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 is active, and 0 otherwise.
Examples ¶
// Check if the sphere primitive is active. int is_active = usd_isactive(0, "/geometry/sphere");
