Quick Checks Before You Convert
AR Quick Look Compatibility
USDZ files for AR Quick Look should be under 50MB for optimal mobile performance. Large GLB files may need mesh simplification before conversion.
Texture Size
Apple recommends texture sizes in power-of-two dimensions (256, 512, 1024, 2048). Non-standard texture sizes from GLB may cause rendering issues on iOS.
Mesh Density
For smooth AR performance on iPhone, keep triangle count under 100K. High-poly GLB models may need decimation before converting to USDZ.
PBR Material Check
USDZ supports PBR materials similar to GLB. Verify that metalness, roughness, and base color maps are present in the GLB before conversion for best AR appearance.
Fixing Common Issues After Conversion
USDZ file does not open on iPhone
Ensure you are using Safari on iOS 12+. AR Quick Look requires Safari or an app with ARKit support. Try opening the USDZ from Files app or Messages.
Model appears without textures in AR
Texture references may not have transferred. Use Reality Converter on Mac to re-embed textures into the USDZ file.
AR model is too large or too small
USDZ uses meters as default units. If the model appears wrong scale in AR, check the unit scale in the source GLB and adjust before converting.
Animations missing in AR Quick Look
AR Quick Look has limited animation support. Complex skeletal animations from GLB may not play. Use Reality Converter to add supported idle animations.
