OCCT conversion workflows

FBX to USD / USDZ

Convert FBX to USD / USDZ 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 FBX geometry for USD / USDZ

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

Read the FBX input with the commercial interface and select the model geometry needed by the receiving application. Inspect the available scene organization and placements before preparing output meshes.

Prepare a USD scene from the imported geometry

Reuse imported mesh geometry or tessellate imported surfaces where needed. Select a static model state for destinations that do not carry scene behavior. Do not infer full animation or material compatibility from the fact that both files are scene formats.

Write USD, USDZ or USDA through the USD component. Map supported names, part placements and appearance into the scene. The component supports meshes, primitives, metadata, materials and animations, but this conversion can preserve only data actually available from the source or explicitly authored by the application.

Validate the converted model

Compare geometry coverage, scale, orientation and part placements. Verify each required appearance or structure property through the complete reader-to-writer route.

Reopen the scene in the receiving USD application. Compare axis conventions, unit scale, hierarchy, repeated parts and material assignments. Review external resources or packaging for the chosen output variant; the retained CAD source remains the reference for precise modeling.

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 FBX to USD / USDZ workflow

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