The canonical way to define Point Instancers in USD is to use "overs" for the prototype instances[1]. However, our current support was coded and tested against setups using Scope prims to contain the prototypes instead. Both approaches are valid USD, but we need to support the canonical way which we so far did not; the overs were incorrectly excluded from processing.
