To export USDZ 3D models for AR, use 3D software (e.g., Blender, Maya) with built-in or plugin USDZ exporters, then save your optimized model in USDZ format.
Optimize the model first: keep polygon counts low, embed textures, and use real-world scaling. Next, access the software’s export menu—like Blender’s “Export > USD” or Maya’s “USD Export”—and select USDZ as the output. Adjust settings (e.g., include materials) to match your AR platform’s needs.
For beginners, try Blender’s free USD exporter: open a simple model, pick USDZ from the export dropdown, save the file, then test it on an Apple device using AR Quick Look to confirm it works in AR.
