Connecting your device

When you’re ready to mirror your effect:

1. Connect mobile device to computer via USB cable.
2. Open Meta Spark Player app on device.

If connecting an iOS device for the first time:

• On macOS 10.14 and below, open iTunes and accept a prompt to trust the device.
• On macOS 10.15 and above, open Finder, select the device, and click Trust.
• On a mobile device, tap Trust when prompted.

If you’re using Meta Spark Player for the first time:

• Enable access to camera and microphone
• Turn on Developer mode and USB debugging in settings (Android only).

Mirroring your project

To mirror your project in the Meta Spark Player app:

1. In Meta Spark Studio, click the Test on device icon in the toolbar.
2. Under Sharing Effect, you'll see your connected device listed.
3. Click Send.

You will now see the effect playing on the device.

If the effect takes a while to send to your device, it may indicate that Meta Spark Studio is compressing the textures in your project. Disable compression for initial testing by selecting None from the dropdown in the Compression section of the Inspector for the selected texture. Use the appropriate compression setting before exporting your effect and test on the device during creation.

Viewing previous versions of effects

To view earlier versions of mirrored projects:

1. Open Meta Spark Player.
2. Tap the menu in top left, select effect and version.
3. Tap Done to see the previous version on the device.

For performance testing:

• Check the FPS displayed when the effect is playing in the Meta Spark Player app.
• Aim for FPS of 30 or higher.
• Tap FPS for more detailed information on effect performance.
• Learn about improving effect performance.
