Template:Shaderparam It adds a constant rim light to the model that appears to come indirectly from the environment. The color of the rim light is directly influenced by ambient light and behave closer to $phongfresnelranges Z component.
Note:Requires $phong to be set to 1.- Todo: Explain similarities and differences of Phong Fresnel ranges.
Warning:
Features no visible effect. however, you can increase $phongfresnelranges Z vector to archive a closer effect.
