This page is about render elements in V-Ray for Unreal.

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 control over the final image when using compositing or image editing applications when re-assembling the final image from its component elements.

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. 

They are accessible from the V-Ray Settings menu.

 

 

Parameters


Denoiser – A render element that progressively applies a denoising operation to the image. The denoising operation detects areas where noise is present and smooths them out.

None – No render element will be generated.

V-Ray Denoiser – V-Ray's denoising algorithm.

NVIDIA AI Denoiser – V-Ray's integration of NVIDIA's AI-based denoising algorithm. The NVIDIA AI denoiser requires an NVIDIA GPU to work.


VRay Render Presets

Each preset group of channels can be activated for render by ticking the Enable option.

Beauty – The Beauty Render Elements are the primary render elements that form V-Ray's pre-composited final render Beauty (RGB_Color).

Filters – Shows only the selected set of channels in the render, disregarding any backgrounds, textures, etc.

Masks – Provides a variety of Render Elements to be used as masks in the compositing process.

Coordinates – The Coordinates Render Elements are based on the scene geometry, but serve different purposes.

Light Select –  Stores direct lighting information from user-selected lights in the scene; can also be limited to the light's raw, diffuse, or specular contribution.

Utilities – This group of Render Elements can be used for troubleshooting purposes.

Custom – You can add any of the render channels again from the Custom option, allowing you to use it with a different setup.
