The Simulator
On this page
Use the Simulator in Meta Spark Studio to quickly see how your effect would look on different devices and from different user’s perspectives, as you’re building your effect.
You can find the Simulator in the top right of the Meta Spark Studio interface.
Seeing how your effect looks from different perspectives
In the Simulator, you’ll see different menu options so you can test what your effect looks like from different users' perspectives. The number of options available varies depending on the experience you selected.
To reveal the options, click the dropdown menu at the top left of the Simulator.
Sharing experience
If you’re creating an effect for a sharing experience, you can select one of the following 2 options:
- User (Sharing) — select this option to see what the person who started the effect sees in a sharing experience (i.e. when sharing the effect in their story, Reel, post or message).
- Capture — this option shows what the person using the effect sees when they press record or capture.
Video calling experiences
If you’re creating an effect for a video calling experience, it’s useful to preview what your effect will look like to different participants during a call. This is especially important because when you make a video call, participant's see your video feed in reverse, which means objects and text may appear backwards unless amended.
If you’ve select a video calling experience, you’ll see the following two additional menu options:
- User (Video Calling) — select this option to see what the person who started the effect sees on a video call on Messenger or Instagram.
- Participant 1 (Video Calling) — this option shows what the person using the effect sees when they press record or capture.
