The Lighting Render Element stores direct lighting and diffuse color information.
The Lighting Render Element stores direct lighting information from lights in the scene and materials as lit by the scene's lighting. This render element can be used to brighten, lessen, or tint just the direct lighting in a composite without affecting indirect light or reflections, for example.
To use render elements, select from the Available render elements column and click the Add button to add the passes you wish to generate at render time. When you render the scene, the added render elements listed in the column on the right, will also render, which can be viewed from the VFB window's channel drop-down menu.
For more information on the parameters on this dialog, see the Render Elements tab page.
The parameters for this render element appear in the Attribute Editor under Extra V-Ray Attributes.

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.specular.vrimg).
