usd_variantselection

Since	17.5

string  usd_variantselection(<stage>stage, string primpath, string variantset)

This function returns the current variant in a given variant set on a 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.

variantset

The variant set name.

Returns

The currently selected variant in a given variant set on a given primitive.

// Get the currently selected variant in the variant set "shapes" on a "shape_shifter" primitive.
string selected_variant = usd_variantselection(0, "/geo/shape_shifter", "shapes");
