Live camera sharing, also called Direct Drive, lets a teammate drive a virtual camera on their iPhone or iPad while everyone else watches the framing update in their browser — regardless of location. Multiple teammates can broadcast at once, and each viewer in the browser chooses whose feed to follow.
How it works
Spark transmits 3D coordinates, not video: the device sends its virtual camera position and the browser re-renders it locally, which is why it stays smooth. This means a teammate in another city can drive the camera without lag, and anyone in the same scene can see where each broadcaster is positioned.
Start broadcasting
- In the Spark iOS app, tap the lightning bolt button at the top of the shooting view.
- The corresponding icon in the browser changes from blue to orange, signaling that the phone is broadcasting.
If the lightning bolt does not engage on the first tap, tap it again. The handshake occasionally needs a second attempt.
Follow a broadcaster
- In the browser, click the orange lightning bolt icon.
- Choose Follow [user name] from the dropdown. If more than one teammate is broadcasting, each appears as a separate option.
- Your browser viewport now mirrors that broadcaster’s camera in real time.
Each broadcaster also appears as a gray camera inside the 3D scene, visible to everyone else in the session.
Recording from a live session
Hitting record on the device while broadcasting plays the scene’s animation while you operate the camera. Stop, name the take, and it appears instantly in the browser timeline for the whole team — teammates without a device can watch and participate purely from the browser.
Limitations
- The broadcaster must have the Spark iOS app open and connected to the same scene.
