Mirroring and the Spark AR Player app

To test the effects you build in Spark AR Studio on the Spark AR Player app, you'll need:

  • An iOS or Android device.
  • A USB cable.
  • A computer with Spark AR Studio installed.
  • A saved project.

To test your effect:

  1. Connect your device to your computer.
  2. Open the app on your device.
  3. Open your project in AR Studio.
  4. Click the device icon in the toolbar.
  5. Select Send To Connected Device - you'll see your device listed here.
  6. Click Send.

You should now see the effect playing on the device.

Yes, if you're offline, you can still view effects that you mirrored with the Spark AR Player app previously.

The Send button in Spark AR Studio is only visible when a mobile device is connected to your computer via a USB cable.

This usually means Spark AR Studio is compressing textures in your project. You could consider disabling compression on your textures for initial testing.

To do this, check the box next to No Compression in each texture’s properties. Make sure you uncheck this box before exporting your effect, and test compressed textures on a device during the creation process.

If you're having trouble previewing your effect with the Spark AR Player app, make sure:

  1. You have the latest versions of both Spark AR Studio and the app. If the tool and the app versions are incompatible, you won't be able to mirror your effect.
  2. Your device is connected to your computer via USB cable correctly.
  3. In the Toolbar under Send to Connected Device you've clicked Send.

What to do depends on whether there’s a blue dot next to the Test on Device button or not.

If there is a blue dot next to the Upload button, Spark AR Studio can’t detect Spark AR Player. Check that:

  1. Spark AR Player is open on your device.
  2. You’re using the latest version of Spark AR Player.
  3. You’ve enabled USB debugging, if you’re using an Android device.

If there isn’t a blue dot next to the Test on Device button

This means Spark AR Studio can’t detect a connection to your phone. Make sure you’ve:

  1. Set Spark AR Studio as a trusted app on your computer, and set the device as a trusted device.
  2. Checked the USB connection between the phone and computer. You might want to try another cable.
  3. Downloaded iTunes if you’re mirroring an effect from a Windows machine to an iOS device.

The Spark AR Player app stores a version of your effect whenever you go to the Spark AR Studio Toolbar and click Send under Send to Connected Device. This means you can view effects that you've previously mirrored on your device, without being connected to your computer or the Internet.

To toggle between versions of your effect:

  1. Tap the menu in the top left.
  2. Select the effect.
  3. Select the version and tap Done.
