Quick Checks Before You Convert
Include MTL for Materials
Without the .mtl companion file, the USDZ output will have default grey materials. Upload both .obj and .mtl for textured AR output.
File Size for Mobile AR
USDZ files for AR Quick Look should be under 50MB. Large OBJ models with high-resolution textures may need optimization before conversion.
Texture Size
Apple recommends power-of-two texture dimensions (256, 512, 1024). Non-standard sizes from OBJ may cause rendering issues on iOS.
Triangle Count
For smooth AR performance on iPhone, keep triangle count under 100K. High-poly OBJ models may need decimation.
Fixing Common Issues After Conversion
USDZ does not open in AR Quick Look
Ensure you are using Safari on iOS 12+. Try opening from Messages or Files app. The USDZ must be served from a web server, not opened as a local file.
Textures missing in AR
MTL file or texture images were not included. Re-upload OBJ with MTL and texture files, or use Reality Converter to embed textures.
Model appears at wrong scale in AR
OBJ uses arbitrary units. USDZ uses meters. Check model dimensions and scale before converting. A 1-unit OBJ model will appear as 1 meter in AR.
Materials look different on iPhone
OBJ/MTL uses a simpler material model than USDZ PBR. Use Reality Converter on Mac to fine-tune materials for accurate AR appearance.
