Use the Illumination pageto set the light sources for the 3D view. Refer to the Draw Guide for more details on setting the illumination.
Setting the illumination
Click any of the eight buttons to switch a directed light source on or off. By default, the second light source is switched on. It is the first of seven normal, uniform light sources. The first light source projects a specular light with highlights.
For the selected light source, you can then choose a color and intensity in the list just below the eight buttons. The brightness values of all lights are added, so use dark colors when you enable multiple lights.
The small preview inside this page has two sliders to set the vertical and horizontal position of the selected light source. The light source always aims to the middle of the object.
The button in the corner of the small preview switches the internal illumination model between a sphere and a cube.
Use the Ambient light list to define the ambient light which shines with a uniform intensity from all directions.
