Selects (switches to) one of the variants stored in a variant set on a primitive.

Houdini Docs: https://www.sidefx.com/docs/houdini/nodes/lop/setvariant.html

USD allows storing multiple named variants of a primitive on the primitive. Each variant can have different attributes, relationships, and children. You can switch the primitive between different variants in different layers. Each primitive can store multiple groups of variants in named variant sets. See Variant Set in Pixar USD glossary.

This node switches the currently selected variant in a variant set. To create variants, use the Add Variant node.
