The OBJ (Wavefront) format is one of the most universal and oldest 3D formats, supported by virtually all 3D modeling software. Converting OBJ to USDZ lets you view your 3D models in augmented reality directly on iPhone, iPad, or Apple Vision Pro.
Launch Eyemesh and open your OBJ file: drag and drop the file into the window, or use File > Open (Cmd+O). Make sure the .mtl file and associated textures are in the same folder as the .obj file. Open the full folder so Eyemesh loads materials automatically.
Inspect your model in the 3D view. Check that textures and materials display correctly. If textures are missing, use the Texture Manager to reassign them manually.
Click the export icon in the toolbar, select the USDZ format, choose a save location, and confirm. The USDZ file is ready — you can send it via AirDrop to an iPhone or embed it on a website.
OBJ (Wavefront) is an open format for describing 3D geometry. It stores vertices, faces, normals, and UV coordinates. Materials are defined in an associated .mtl file, with textures stored as separate image files. Its simplicity makes it a universal exchange format, though it does not support animations.
USDZ is a 3D archive format developed by Apple in collaboration with Pixar. It packages a USD file with all its textures into a single uncompressed file. It is natively supported by iOS, iPadOS, macOS, and visionOS for augmented reality display via AR Quick Look.
Download Eyemesh on the Mac App Store and convert your OBJ files to USDZ in just a few clicks.
