OCCT conversion workflows

USD / USDZ to FBX

Convert USD / USDZ to FBX through a mesh workflow. Prepare geometry, map supported data and validate the result in the receiving application.

Build this conversion into your application with OCCT readers, writers and the commercial components identified below.

Prepare USD / USDZ geometry for FBX

The USD / USDZ-to-FBX route uses the USD / USDZ reader, mesh preparation and the FBX writer. Choose the geometry and representation required by the destination 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 mesh geometry for FBX delivery

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 mesh geometry with the commercial FBX interface. Prepare the supported scene and placement mapping required by the receiving application. Check appearance and other attributes individually rather than assuming all source properties have an FBX writer mapping.

Validate the converted model

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 FBX in the destination and compare scale, orientation, geometry coverage and placements. Verify the actual version and property mapping needed by that application. Retain the engineering source for information that the scene derivative cannot carry.

For repeated jobs, retain the source, preparation settings and representative output checks. Discuss this conversion with the input files, destination application and required geometry and attributes.

Conversion integration

Build a USD / USDZ to FBX workflow

Share the source and receiving applications, representative files, required attributes and throughput. We can scope SDK evaluation or an integrated conversion service.
