Product: USD Scene Unpacker — RVA STUDIO

Version: 1.0.0

Engine: UE 5.6 – 5.7

Type: Editor Utility Widget (Editor-only, zero runtime cost)


Introduction

USD Scene Unpacker converts imported USD actor hierarchies into native Unreal Engine actors, giving you a clean scene ready for Merge, Nanite, HLOD, and ISM pipelines.

It processes the entire hierarchy in two clicks. Analyse first — get a classification report showing exactly how many meshes, lights, cameras, and empty actors are in the tree. Then Unpack — every StaticMesh instance becomes a proper StaticMeshActor, lights and cameras are detached and preserved, empty containers are cleaned up. The entire operation is a single undo step.

This tool requires a USD scene properly imported into UE — not opened via the USD Stage Actor live link. Please open the USD Stage Editor and go to Actions → Import.
