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



The VRayReflectHighlightGlossiness render element returns a grayscale image that corresponds to the value in the Highlight Glossiness of the materials in the scene.

Since V-Ray Next, reflection highlight glossiness can no longer be controlled separately from reflection glossiness in VRayMtl. This render element now contains the same information as VRayMtlReflectGlossiness.




This render element is enabled through the Render Elements tab of the Render Setup window in 3ds Max and displays its parameters in a rollout at the bottom of the window:

VRayVFB – When enabled, the render element appears in the V-Ray Virtual Frame Buffer.

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