Lighting Tutorial

Lets change the properties of the light...

Here is a brief definition of each:

Ambient   Is light whose direction is impossible to determine. When it hits a surface, it is scattered in all directions.
Diffuse   Comes from one direction. When it hits a surface, it is scattered in all directions.
Specular   Comes from one direction. When it hits a surface, it bounces off in one direction. Think of specular light as shininess.

Note how the material properties of the object react with the properties of the light. For example, if you set the specular property of the light to blue, and the specular property of the object to black, you will not see the effect of the light's specular property. If change the object's specular property to white, all specular colors coming from the light will have an effect.

The Directional or Positional options control how the light effects the scene. If the light is a Spot light, you should check Positional
