// Class : PolylightEffect
|
|
// Description : A PolylightEffect can be used on a node to define a
|
|
// LightGroup for that node. A LightGroup contains
|
|
// PolylightNodes which are essentially nodes that add
|
|
// color to the polygons of a model based on distance.
|
|
// PolylightNode is a cheap way to get lighting effects
|
|
// specially for night scenes
