Point clouds are sent by the **Point Streamer**, and scalar and vector data is sent separately by the [[Message Streamer|Publishers/Message Streamer]].
## Stream Channels
-
Every session, device and device group in the workspace is available as a stream channel. Channels are listed in the Streaming window (_Window → Streaming_), where each one can be toggled on or off. A device group's channel carries the merged cloud of every device inside it.
-
-
A channel's address is its label (or ID if it has none), prefixed by the labels of any groups it sits inside, e.g. `stage/left`. Clients subscribe to channels by address, or to every channel at once.
+
Every session, device and device group in the workspace is available as a stream channel. Channels are listed in the Streaming window (_Window → Streaming_), where they can be toggled on or off.
The dot beside each channel shows its status:
- **Grey**: disabled.
- **Blue**: live, but no clients are subscribed.
- **Green**: at least one client is subscribed.
-
When a channel is disabled, one last empty cloud is sent so clients clear what they're displaying.
