Property Value

The Fresnel factor.


The default value is 1. Use 0 to disable Fresnel lighting; this makes the environment map visible independent of the viewing angle. Use a higher value to make the environment map visible around silhouette edges; use a lower value to make the environment map visible everywhere. Fresnel lighting only affects the environment map color (RGB values), alpha is not affected. Control the intensity of the color values using EnvironmentMapAmount; control the intensity of the alpha value with EnvironmentMapSpecular.
