# \&solo

Viewer-Side Option! ([`&room`](/advanced-settings/setup-parameters/room.md))

## Details

`&solo` is used to bring a solo-link of a guest in a room into OBS Studio.\
<https://vdo.ninja/?view=streamid1&room=roomname&solo>

This tells the system to only view `streamid1` in the specified room. `&solo` and [`&scene`](/advanced-settings/mixer-scene-parameters/scene.md) also tells the system not to be a publisher, but a viewer.

This parameter behaves just as [`&scene`](/advanced-settings/mixer-scene-parameters/scene.md). The only difference is, that the system does not apply custom 'layouts' to `&solo` links.

Links updates in the director's room from Version 22 onwards.

### Alternative using \&optimize=0

If using a normal manual scene, such as \&scene=3, you can add [\&optimize=0](#alternative-using-and-optimize-0) to the scene URL to enable a mode that is similar to \&solo. It's one of a few different ways to have permanent generic scene links that you can place specific guests into with varying stream IDs. There's also slots, however \&optimize=0 is tweaked for low CPU and network usage, at the cost of a slight added delay in adding a guest to the scene
