This page gives an overview of the workflow using Render Elements.


Page Contents



The V-Ray Render Elements are a way to break out renders into their component parts such as diffuse color, reflections, shadows, mattes, etc. This gives fine control of the final image when re-assembling the final image from its component elements in compositing or image editing applications.

Render Elements are generated at render time based on the ones chosen by the user 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 more information about individual render elements and how they are used in compositing, see the Render Elements section.

All render elements support native V-Ray materials. Some render elements also support standard Modo materials.




 UI Paths:

V-Ray Menu > Render Settings -> Render Elements

||V-Ray Toolbar|| > V-Ray Render Elements button


||V-Ray Toolbox|| > Render Elements button




A render element's parameter rollout can be accessed by selecting the render element's name from the Render Elements panel. Note that only the listed parameters below are supported by V-Ray for Modo.



Enable – When enabled, the render element's parameters are put into effect. This can be used to remove the output from the rendering without deleting it.

Output Filename – Sets the filename and location, only used on the render output item that is set to the Final Color Output effect.

Antialiasing – When enabled, applies anti-aliasing to the render element. Should be disabled when using the Velocity Render Element .

Image Processing – When enabled, applies post processing to the rendered image. This is ignored for the Alpha render outputs.

Z-Depth Output – Sets the filename and location of the Z Depth pass.

Remap Pixel Values – When enabled, this option adjusts the pixel values to low dynamic range images.

Maximum Depth – Sets a "clipping plane" for the black point beyond which will be rendered pure black. Accessible when Remap Pixel Values is enabled under the Z Depth render element.

Motion Vector Output – Sets the filename and location of the Motion Vector (Modo) or Velocity (V-Ray) pass.

Maximum Motion – Sets the maximum distance a blurred pixel would travel. Accessible when Remap Pixel Values is enabled under the Velocity render element.

Ambient Occlusion Output – Sets the filename and location of the Ambient Occlusion pass.

Occlusion Rays – Sets the number of random rays shooting out per surface when shading a pixel for Ambient Occlusion.

Occlusion Range – Sets the length of the Ambient Occlusion rays fired from a surface.


  • The Render Elements drop-down has a circular button in the top right corner which, when toggled, allows for the window to be detached from the UI and moved wherever needed. Click this button once more to close the window.
