By default, your scene has only one renderable camera (the original perspective camera) that renders all objects in your scene. You can change this to render only selected objects in your scene.

If you add another camera to your scene and want to make it renderable (or you would like to make one of the default orthographic cameras renderable), you must set this camera to renderable (see Make an existing camera renderable).

To render only selected objects in your scene

1. Select the objects you want to render.
2. In the File Output section of the Render Settings window, select the camera from the Renderable Camera drop-down list.
3. In the Render View window, select Render>Render Selected Objects Only.
4. Render the scene.
