Troubleshooting

The camera won't open!
I have an iOS device
We recommend using the Safari browser on iOS.
Make sure your device is updated with iOS version 13.0.0 or above.
Allow access to the website when prompted for camera permission. If you are not prompted for camera permission, make sure you enable your browser to have permission to access the camera.
Go to Settings on your device
Scroll down and open Safari tab
Ensure Camera & Microphone are set to Allow
I have an Android device
Make sure you are using the latest Chrome browser version. We advise setting Chrome as your default browser through your phone's settings as it tends to work better than the other preinstalled browsers. 
Also, make sure you enable your browser to have permission to access the camera and allow access to the website when prompted for camera permission.
The model is too big or very small!
If you chose option 1 or option 3, scale the model by pinching the screen with two fingers.
If you chose option 2, you can change the size of the model by adding a metadata key named scale to the 3D models. See how in the Data Page section of the documentation.
I am getting errors relating to ARKit/ARCore!
Some apps or browsers require that your device is compatible with ARKit or ARCore.
Make sure to have Google Play Services for AR installed on your Android device.
I am getting errors around not having enough key points!
Make sure to upload high-contrast images with multiple details in the shot. 
When uploading an image file to be used as an image target, our system checks for the contrast and detail complexity of the uploaded image. This validates that AR-enabled cameras will be able to detect the image.
Here is an example of a good image:

My OBJ files fail to upload!
Are you uploading multiple files (.obj, .mtl, and .png) together?
Make sure that the .obj and .mtl file has the same name and that this.mtl filename is referenced inside the .obj.
Are you uploading a .zip file with the .obj, .mtl, and .png inside?
Make sure that the .mtl filename is referenced inside the .obj.
When adding multiple assets from local storage, we recommend zipping them first and uploading the ZIP file.
I need to change a 3D model’s material
There are two cases where changing the material on your 3D model in Unity makes sense.
1.You don’t want to use Blender or some other 3D modeling software
2.Your model’s material looks different in Unity than what you see in Blender/your 3D modeling software (or it doesn’t show up at all and your object is white).
Here’s a quick way to get the right material on your 3D object, even if you didn’t create the asset yourself:
