Read USD / USDZ for PLY output
A USD / USDZ-to-PLY workflow connects the USD / USDZ reader to the PLY writer. Select the model items and output representation needed by the receiving application.
Read USD, USDZ or USDA with the USD component. It supports meshes, primitives, names, hierarchy, colors, metadata, materials and animations. Select the scene nodes and the scene state required for the receiving workflow.
Select the polygon data required by the PLY consumer
Prepare the imported meshes and any supported primitives for the target representation. For a static output, select or evaluate the required animation state in the application and apply the corresponding placements. Source animation support does not make a static CAD or mesh format animated.
Write a polygonal derivative with the OCCT PLY interface. Agree on the mesh and property fields needed by the consumer: the PLY extension alone does not guarantee compatible color or other per-element property handling. Keep assembly and CAD metadata separately when it has no destination mapping.
Check the PLY result
Validate unit scale, orientation, nested transforms and geometry coverage. USD materials, animation and metadata need individual mapping checks; only properties supported by the destination can travel with the converted model.
Reopen the PLY in the downstream processing tool and compare units, bounds, surface coverage and the expected properties. Native PLY support in the catalog is write-only; this route does not imply a native PLY reader for the reverse direction.
Discuss this conversion with the producing and receiving applications, representative files and required geometry and attributes. Compare the reader/writer catalog when a different representation is needed.
