The Render Elements tab is available in the Render Setup window when either V-Ray or V-Ray GPU is selected as the Renderer. Render Elements are a way to break out renders into their component parts such as diffuse color, reflections, shadows, mattes, etc. to give the ability to fine-tune aspects of the image in compositing or image editing applications. For information on the render elements available in V-Ray and how to generate and use them, see the Render Elements page. On the right is the Render Elements tab when V-Ray is selected as Renderer.
