Reflection glossiness

This page gives some basic details about the Reflection Glossiness render element and how it is used in compositing.

Overview

The Reflection Glossiness Render Element stores the image's reflection glossiness as a grayscale image that represents the degree of Reflection Glossiness set for materials in the scene. White areas have the most reflection glossiness, while dark areas have little.

The amount of reflection glossiness for a material is set by its Reflection Glossiness parameter. For example, V-Ray Material (VRayMtl) has a Reflection Glossiness parameter, and and VRayFastSSS2 has a Specular glossiness parameter that goes in the Reflection Glossiness render element.

UI Path: ||Display Render Settings button|| > Render Elements tab > Reflection glossiness

Attributes

The parameters for this render element appear in the Attribute Editor under Extra V-Ray Attributes.

Enabled – When checked, the render element appears in the V-Ray Virtual Frame Buffer.

Deep output – Specifies whether to include this render element in deep images.

Filename suffix – The text added to the end of the rendered file, when saved as a separate file (e.g. myrender.reflGloss.vrimg).

Note

• Since V-Ray Next, the Reflection Hilight Glossiness option has been removed from the UI as it can no longer be controlled separately from the Reflection Glossiness in VRayMtl. As there will be no difference between the Reflection Hilight Glossiness Render Element and the Reflection Glossiness one, the Reflection Hilight Glossiness Render Element is no longer available.
