Read USD / USDZ for OBJ output
A USD / USDZ-to-OBJ workflow connects the USD / USDZ reader to the OBJ 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.
Prepare polygonal geometry for OBJ
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 the selected surface mesh with the OBJ interface. Establish whether the consumer needs per-part grouping, normals or supported appearance information, and preserve any associated material resources produced by the writer. A polygon file is not a replacement for the full CAD document.
Check the OBJ 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.
Check the OBJ in the receiving graphics or geometry tool, including scale, face orientation, grouping and companion-file references. Where a flat mesh cannot retain the original assembly relationships, keep that engineering information separately.
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.
