The best way to save a USDZ 3D model is to use software with native USDZ support (e.g., Blender with USD add-ons, Adobe Dimension, Apple Reality Converter) and export directly after editing.
- Native support preserves your model’s textures, animations, and metadata—critical for AR/VR or Apple device (iPhone/iPad) AR experiences—without conversion glitches. - If your tool doesn’t export USDZ, use a reliable converter like Apple’s Reality Converter (for macOS) to turn .usd or .obj files into USDZ while keeping quality intact.
In short, prioritize native export first, then use a trusted converter if needed.
