This page provides information about the Specular render channel in V-Ray for Blender.
Overview
The Specular Render Channel is an image that stores specular reflection (basically put, highlight) information calculated from the material's reflection value in the scene. Specular reflection is defined as the reflection of light from a surface in a single particular reflection, as opposed to a diffuse reflection, which is reflected at many angles.
The brighter the area, the more highlighted reflection the object exhibits in the render. If the Reflection Color parameter of a material is colored, the Specular highlights will be colored.

Properties
See the Render Channels page to find out where you can find these properties.
Channel Name – Customizable name for the render channel.
Enable Deep Output – Specifies whether to include this render channel in deep images.
Color Mapping –
Consider For Anti-aliasing – When enabled, anti-aliasing is used where possible.
Filtering – Applies an image filter to this channel.
Derive Raw Channels – Generates data in the raw channels by combining the respective color and the filter color channels.
Vfb Color Corrections – Applies the post-render color adjustments made from the VFB.
Denoise – Enables the render element's denoising, provided the Denoiser is enabled.
Common Uses
The Specular render channel is useful for changing the final image's specular appearance during compositing. In the example, the specular reflections are brightened and tinted with a cooler color. See the render before and after compositing.
