Turning Lights On and Off

Individual lighting fixtures or entire light groups can be turned on or off to achieve the desired lighting effects in a rendered image. When you turn on or off lights in a 3D view, the settings are saved as part of the view properties, and they affect that view only. They do not affect rendered images for any other 3D views.

If a lighting fixture is a nested family that is not shared, you cannot control individual light sources in the fixture. Instead, you turn the entire lighting fixture on or off. See Sharing a Lighting Fixture Family.

NoteRender time is directly proportional to the number of lights in the scene. See Render Performance and Lighting.

To turn lights on or off

  1. In a Revit Architecture project, open a 3D view.
  2. On the View Control Bar, click (Show Rendering Dialog).
  3. In the Rendering dialog, under Lighting, for Scheme, select a setting that includes artificial lights.
  4. Click Artificial Lights.
  5. In the Artificial Lights dialog, under On/Off, select individual lighting fixtures or light groups to include them in the rendered image. Clear the check boxes to omit the lights in the rendered image.

    You can also enter values in the Dimming column to dim individual lighting fixtures or entire light groups. See Dimming Lights.

  6. Click OK.
  7. To see the results, render the image.
