This page provides information on the Bump Normals Render Element which creates a normal-style image from the camera view from bumps and normals in the scene.

Overview
V-Ray Bump Normals is a render element that stores the camera view as a normal map. The normals are generated using screen space which uses the XYZ orientation of the camera view. With Screen space, the X axis runs left-right across the view, Y runs up-down, and Z points out of the screen. Bump maps are also represented in this render element.
This render element is similar to the Normals Render Element Render Element that does not include bump maps.
The Bump Normal Render Element is useful for adjusting lighting that comes from a particular direction. For example, faces of objects pointing toward the camera will be predominantly blue in the bump normals, so the lighting on such objects can be adjusted by using the blue channel in compositing software.
