Applying Selective Lighting

When you add a light source to a scene, the light is applied to all surfaces. You may want a light source to only illuminate an individual or specific group of surfaces, or prevent a light source from illuminating an individual or specific group of surfaces.

To apply selective lighting:

1. Add multiple surfaces to the scene. See Adding Surfaces.
2. Add a light to the scene.

   All surfaces are illuminated.

   
   

3. Select Lighting from the Edit Mode box.
4. To illuminate only a selected surface, click the light node, and drag it to an axis or image you want illuminated.

   The selected object is connected to the light source by a blue dotted line with an arrow, and only the selected surfaces are illuminated.

5. To exclude a surface, hold the Alt key while clicking and dragging from the light source to the surface you do not want illuminated.

   Excluded surfaces are connected to the light source by a red dotted line with an “X”, and they are not illuminated. In the following example, all surfaces are illuminated, except for image3, which is excluded.
