fresnelrangestexture is a 2d texture merged from several 1d textures to control the Fresnel term of blinn-phong specular and rimlight
- The V coordinate of the texture corresponds to WarpIndex. If there is an alpha channel of $masks1, you can control WarpIndex through alpha to select different Fresnel mappings
- The U coordinate of the texture corresponds to the mapping relationship to the Fresnel value (the intensity of Fresnel corresponds to the coordinate value of U
When $fresnelrangestexture exists, $phongfresnelranges is invalid
Fresnel will force the use of normalized VdotN as a constant sampling value to map fresnelrangestexture
fresnelrangestexture consists of three channels of rgb
- Channel R: No effect
- Channel G: After sampling, remap VdotN to obtain the final blinn-phong specular Fresnel mask
- Channel B: After sampling, multiply it with the RimMask (R channel) of $masks1 to obtain the Fresnel mask of AmbientReflection (rimlight related to the environment)
