The Total Lighting Render Element stores all direct and indirect lighting in the scene.
The Total Lighting Render Element is a color image that includes the effects of both direct and indirect lighting on materials in the scene, including the diffuse component. It is a result of adding the vrayRE_Lighting and vrayRE_GI render elements, or of multiplying the vrayRE_Raw_Total_Light and vrayRE_Diffuse Render Elements.
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.
