An in depth look at each setting within a V-Ray material. You can jump to a specific section using the links below. DiffuseReflectionRefractionTranslucencyBRDFOptionsMapsReflect/Refract interpolation Diffuse Diffuse This is the actual colour of the surface, reflection and refraction colours can affect the visual appearance of this colour. Roughness Can be used to simulate dust on a surface by controlling the way the surface reflects direct light. Reflection Reflect Like diffuse it uses a colour value to determine the reflection strength. Fresnel reflections Most materials except metals have a Fresnel reflection, making the reflection strong at glancing angles but weak at more front on angles. Fresnel IOR IOR stands for index of refraction and is used to measure how light refracts through a surface relative to the viewing angle (Yourself), confusing at first but read on. You can find many IOR tables on the internet and they all give different values for real world materials. Highlight glossiness
