Trace Reflections – Check this option to enable reflections for the material.
Max depth – The number of times a ray can be reflected. Scenes with lots of reflective and refractive surfaces may require higher values to look correct. See the Reflection Depth example above for illustration.
Dim distance On – Enables the Dim distance parameter which allows you to stop tracing reflection rays after a certain distance.
Dim distance – Specifies a distance after which the reflection rays will not be traced.
Dim fall off – A fall off radius for the dim distance.
Reflect On Back Side – When disabled, V-Ray will calculate reflections for the front side of objects only. Checking it will make V-Ray calculate the reflections for the back sides of objects too.
Affect Channels – Allows the user to specify which channels are going to be affected by the reflectivity of the material.
Color Only – The reflectivity will affect only the RGB channel of the final render. Color+alpha – Causes the material to transmit the alpha of the reflected objects, instead of displaying an opaque alpha. All channels – All channels and render elements will be affected by the reflectivity of the material. This option is not available for V-Ray GPU.
