You
		can
		adjust the direction, intensity, and color of light in the shaded view of a model. You can
		add light sources of various types, and modify their characteristics to illuminate the model
		as needed. 
		
	You can change the appearance of the model to enhance or reduce the effect of lighting properties.
Light Types
There are several types of light source:
| Ambient light | Illuminates the model evenly from all directions. In a room with white walls, the level of ambient light is high, because the light reflects off the walls and other objects.
 | 
| Directional light | Comes from a source that is infinitely far away from the model. It is a columned light source consisting of parallel rays from a single direction, like the sun.
 | 
| Point light | Comes from a very small light source located at a specific coordinate in the model space. This type of light source emits light in all directions. The effect is like a tiny light bulb floating in space.
 | 
| Spot light | Comes from a restricted, focused light with a cone-shaped beam that is brightest at its center. A spot light can be aimed at a specific area of the model. You can adjust the position and distance of the light source relative to the model, and you can adjust the angle through which the beam spreads.

System Lighting Defaults
By default, the
				
Lights
			
 folder under 
Scene, Lights, and Cameras in the DisplayManager
			contains one 
Ambient light and three 
Directional lights. The default lights are set by the
				scene.
 When PhotoView 360 is added in, the
					
Lights
				
 folder is renamed to
					
SOLIDWORKS Lights
				
 and a 
PhotoView 360
					Lights
				
 folder also appears. The default
				lighting for PhotoView 360 is 
Primary PhotoView 360 Lighting
				
 (scene environment). The scene
				environment is an HDR (High Dynamic Range) image that surrounds the scene
				spherically, creating realistic light and reflections.
				- You can turn the Ambient
					light on or off, but you cannot delete it or add additional Ambient lights. 
- You can turn the Directional light sources on or off, or delete them. You can
					also add additional Directional light
					sources. 
- By default, directional, spot, and
					point lights are on in SOLIDWORKS and off in PhotoView
					360.
- The maximum number of light sources in any document is nine (the
						Ambient light and eight others in any
					combination).
