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.
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.

NoteTo remove the inclusion or exclusion link, while still in Lighting mode, click and drag over the line that connects the light source to the axis or image.
