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



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 SketchUp, see the Supported Render Elements page.




UI Paths


||V-Ray Asset Editor|| > Create Asset (left-click) > Render Elements



||V-Ray Asset Editor|| > Render Elements (right-click to add Render Elements)



The creation of render elements is available from two places in the Asset Editor: from the Create Asset button and the Render Elements category icon (top). If the Render Elements category is empty, left- or right-clicking the icon prompts you to create a new asset. Otherwise, it selects the category in which case right-click opens the creation menu.

The Asset creation dropdown lists remain active when the Ctrl (Cmd on Mac OS) key is held, allowing the creation of multiple assets in quick succession. The Asset creation dropdown lists can be activated via the Create Asset button or the Asset Category icons. 




A number of Render Elements have a Denoise option in their Parameters rollout. It enables the render element's denoising, provided the Denoiser option is switched on for the scene.

  • 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 slightly slow down the final image rendering, depending on the number of elements that are selected. They have no effect on GI/reflection etc. calculations.
  • Creating or removing render elements does not work during interactive rendering. The changes take effect only after the render process is restarted.
  • The context options of the Color Slot allow to Copy and Paste a color from one color slot to another, as well as to Reset the color selection to a default value.
  • A new option allows VFB color corrections to be applied to each of the render channels when they are saved to disk as separate image files.
