This section contains information on the Render Elements found in V-Ray for Rhino.

VFB Channels Overview

Render Elements are a way to break out renders into their component parts such as diffuse color, reflections, shadows, mattes, etc. This gives fine tune control in the final image using compositing or image editing applications when re-assembling the final image from its component elements. Render elements are also sometimes known as render passes.

Render Elements are generated at render time based on the ones you choose before rendering. Most render elements have parameters that can be set to customize the render element or its later use in compositing software. These parameters are described on each render element's individual page, along with common uses and any notes on their generation and usage.

For a complete list of render elements supported in Rhino, see the Supported Render Elements page.

Render Elements – In order for V-Ray to render individual render elements, you must add the desired element from the search list. For a complete list of render elements supported in Rhino, see the Supported Render Elements page.



Additional Rollouts

The following rollouts are accessible within the Render Elements rollout when their respective element is added to the list:

  • ExtraTex - Used to render the entire scene with one texture mapped on all objects.
  • Denoiser - Takes an existing render and applies a denoising operation to it.
  • ZDepth - Provides ZDepth information of objects.

  • V-Ray always anti-aliases with respect to the RGB color channel. Therefore other channels may appear jagged or noisy in areas where V-Ray has placed fewer samples.
  • Render elements will render in Distributed rendering mode.
  • Render elements require additional storage when rendering and thus increase the amount of RAM taken during the rendering. When rendering to the V-Ray VFB, you can reduce this memory by rendering directly to a .vrimg file on disk and not storing the final image in memory.
  • Render elements may slow down the final image rendering a little bit, depending on the number of elements that the user has selected. They have no effect on GI/reflection etc. calculations.
