Pairing to Snapchat
With Lens Studio, you can preview your Lens creations inside Snapchat. When paired, any changes you make in Lens Studio are reflected in a preview Lens on your mobile device. Previewing your Lens inside Snapchat will help you test and iterate on the Lens' user experience.
To pair Snapchat with Lens Studio, you'll need the latest version of Snapchat as well as the latest version of Lens Studio.
Pairing Your Device
To preview your Lens on your device, first you must pair your device with Lens Studio.
Pair Your Devicebutton in the top right corner of Lens Studio
You should see a Snapcode pop up. This Snapcode is unique to your Lens Studio

In Snapchat, point your camera at the Snapcode
Press and hold the image of the Snapcode to scan it
You should see a prompt to Pair with Lens Studio
When paired, you should see the
Your Device Pairedmessage in Lens Studio
The pairing process can take up to 30 seconds depending on your network. After clicking
Pair, please allow some time for the device to find and connect to Lens Studio.
You can only have one device paired to Lens Studio at a time. If you want to pair a different device, you first need to disconnect your currently paired device. To do this, select
Pairing -> Disconnect in Lens Studio's menu bar.
If you want to remove the paired lens from Snapchat, first open Snapchat. Then, go to
Settings. There, select
Additional Services -> Manage -> Lens Studio -> Pair Status -> Tap to
Unpair. This will unpair your device and remove the paired Lens from your Lens carousel. Note, you might have to force quit and reopen Snapchat if you want the Lens removed immediately.
