Light Affect OpenGL

Affect OpenGL

This option is for display purposes only. It will not change the effect a light has on a rendered image. With this option you can prevent the light from affecting Layout’s display, which uses OpenGL. This is important since the number of lights that can affect an OpenGL display is usually limited to 8 depending on the graphics card (if your card supports more, see the GL options tab of the Preferences Panel to increase your maximum).
