This material should be used sparingly, as it may cause the light source calculation to blow up if it is applied to many small surfaces. |
569 |
|
This material is only supported for flat surfaces such as <a HREF="#Polygon">polygons</a> and <a HREF="#Ring">rings</a>. |

|
The arguments are simply the RGB reflectance values, which should be between 0 and 1. |
