What Is OBS Virtual Camera for Cam Models?

OBS Virtual Camera lets another application treat your finished OBS scene as a webcam. For a cam model, that can be useful when a platform or browser expects a camera device instead of an RTMP stream.

The simple explanation

Your physical webcam captures video. OBS turns that feed into a composed scene. OBS Virtual Camera exposes that composed scene to another application as though it were a webcam.

Why models use it

• Overlays and graphics created in OBS
• Scenes for BRB or transition screens
• One composed camera source for another app
• Workflows where the platform does not use an RTMP encoder connection

Virtual Camera vs Stream Key

These solve different problems. A Stream Key/RTMP workflow sends an encoded broadcast to a platform's ingest service. A Virtual Camera exposes a camera device locally so another application can capture it. A model may use either one depending on the platform.

A current Lovense example

Lovense's current Webcam 2 guide explicitly documents both routes: using OBS and then selecting OBS Virtual Camera on a livestream site, or connecting the webcam directly to the site when OBS is not needed.

The common mistake

A model creates an OBS scene and then opens a site that still has the physical webcam selected. The site may show the raw camera rather than the finished scene—or another application may already have the camera locked.

A clean troubleshooting sequence

1. Confirm the physical webcam works in OBS.
2. Confirm your scene looks correct.
3. Start OBS Virtual Camera.
4. Open the platform's camera selector.
5. Choose OBS Virtual Camera.
6. Check preview and audio before going live.
