Fresnel reflections calculation also interpolates glossy reflections and refractions on a 'microfacet' level to ensure more natural effect with less brightening of the grazing edges as the glossiness is decreased. Some materials in nature (glass, etc.) reflect light in this manner. For more information, see the V-Ray Roughness page.įresnel reflections – When enabled, the reflection strength becomes dependent on the viewing angle of the surface. If BRDF is set to Use roughness, this option becomes Reflection roughness. For more information, see the Reflection Glossiness example below.
A value of 1.0 means perfect mirror-like reflection lower values produce blurry or glossy reflections. For more information, see the Reflection Color example below.
This parameter can be mapped with a texture in the Maps rollout.
Note that the reflection color dims the diffuse surface color based on the Energy preservation mode option. Reflect – Specifies the amount of reflection and the reflection color.
