check_ancestral#

omni.usd.check_ancestral(prim: Prim) → bool#

Check if prim is brought into composition by its ancestor.

A prim is considered ancestral if it only exists because a composition arc (reference, inherit, etc.) on one of its ancestors brought it in. A prim that has a direct ``def`` specifier in the root layer stack is NOT ancestral, even if its parent has composition arcs that propagate ancestral nodes into this prim’s index.
