How to

Putting the avatar in OBS, Zoom and Meet

Orb Studio deliberately does not install a virtual camera driver. Here is the route that works instead — a chromeless always-on-top window, the Broadcast preset, and OBS as the bridge.

The window is the source

Click Camera in the top bar and Orb Studio opens a clean, chromeless window containing nothing but the avatar. It stays on top of other windows, and it is titled Orb Camera — that title is the thing you point a capture source at.

In OBS: Sources, then Window Capture, then pick Orb Camera. For Zoom, Meet or Teams you can share that window directly, or route OBS's Virtual Camera into the meeting app as your camera.

Keying it over a scene

Select the Broadcast preset before you capture. It swaps the avatar's background for flat chroma green, which gives OBS's Chroma Key filter a clean edge to work with. The avatar then floats over your screen share, your slides, or your game capture rather than sitting in a box.

This is the same mechanism the Editor uses for chroma key on the timeline, so a look you set up for streaming transfers to a recorded edit without re-doing it.

Why there is no virtual camera driver

A system-level virtual camera on macOS requires a signed CoreMediaIO extension. Shipping one means an installer that plants a system extension on your machine, a signing chain to maintain, and a component that keeps running after the app quits.

Orb Studio does not do that. OBS already solved the problem, its Virtual Camera is well-tested, and routing through it keeps Orb Studio a normal application you can delete by dragging it to the trash. If you are upgrading from an older build, note the capture window was renamed — re-select it once in OBS and the source reconnects.
