+ opposing sides would light one side in red and the other in blue, adding\r

+ neutralize each other making it look like having no direction.\r

+ is modifying the direction applied from directional lights, making it go closer and closer\r
+ to the surface normal the bigger is the amount of radiosity received.\r
