I have a question about the Fresnel value in the material panel, under the ‘mirror’ section. Normally, the Fresnel effect controls how reflective the material is depending on the angle between the surface and the viewing direction. Generally, the larger the angle the more reflective a material becomes.
My question is, how can I invert this? I want it to become more reflective the smaller the angle. I have tried entering a negative number but that doesn’t work.
