reflectionColor – The color of the reflection.
reflectionTexmap – Sets the map to use (if any) to set the reflection colors.
frontReflectivity – Sets the level of reflectivity for faces that face the viewing angle. Values can range from 0.0 to 1.0, with 1.0 setting the highest degree of reflectivity.
sideReflectivity – Sets the level of reflectivity for faces that face away from the viewing angle at a 90-degree angle. Values can range from 0.0 to 1.0, with 1.0 setting the highest degree of reflectivity.
curveDegree – Sets the degree of curvature for the curve that interpolates the front and side reflectivity. Values can range from 0.0 to 100.0.
One use for VRayFakeFresnelTex is to give a VRayMtl a stronger Fresnel effect on reflections than the Fresnel reflections option. Below is a simplified example to show how VRayFakeFresnelTex changes the degree of reflectivity on a spherical object.
A VRayMtl was applied to both objects below, with different material setups. Where VRayFakeFresnelTex is used, the front of the object (the part that faces the camera) is much less reflective than the sides of the object. The degree of reflectivity set by VRayFakeFresnelTex affects both the reflected background and the reflection of the rectangular light source.
