| Property | Description |
|---|---|
| Direction | This is the direction that the light source is pointing, as a vector in view coordinates. Positive X lights the model's left side, positive Y lights its bottom, and positive Z lights its front, from the user's point of view. Only the vector's direction matters; its length is ignored. The vector needn't be normalized, but at least one of its coordinates must be non-zero. Negative Z causes back-lighting, which is usually unhelpful. |
| Diffuse | This value specifies the brightness of the diffuse lighting. It generally ranges from zero to one. |
| Ambient | This value specifies the brightness of the ambient lighting. It generally ranges from zero to one. Ambient lighting is unaffected by direction. |
| Specular | This value specifies the brightness of the specular lighting. It generally ranges from zero to one. Specular lighting only has an effect if Highlights are enabled. |
| Power | This value specifies the sharpness of specular highlights. The higher the value, the sharper the highlight. |
