Yes, all new lights default to these values. Setting the color of a light to viz.RED will set the diffuse to [1,0,0] and leave the ambient/specular alone. If you want to change those values then you can use the <node>.ambient and <node>.specular commands.
Here are the defaults for the other values: spotexponent: 0.0 spread: 180 constant attenuation: 1 linear attenuation: 0 quadratic attenuation: 0 intensity: 1 Translating a light has the same effect as setting the position. |
