USDZ 3D models often have missing textures because textures aren’t always embedded directly or referenced file paths break when shared.
USDZ can store textures as external links instead of embedding them—if those linked files are lost, moved, or paths change (e.g., sending just the .usdz without texture files), textures won’t load. It also happens if the creator forgot to enable "embed textures" in their 3D software’s export settings.
If you’re dealing with a USDZ model missing textures, try asking the creator for the original texture files or re-export the model from your 3D tool with texture embedding turned on (most tools like Blender or Maya have this option).
