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 useful to get Matte render elements (e.g. Cryptomatte, Matte ID, etc.) in the reflections. When selecting the Affect All channels option, be aware that the information of the respective component affects all render elements, therefore the Back to Beauty composition will not match the RGB result from the renderer. |
GTR Energy Compensation – Compensates GTR lost energy and an accurate Fresnel formula for conductors is used for metals. This option is enabled by default for all newly created materials. |
