This page provides information about the Raw Refraction Render Element in V-Ray for Cinema 4D.


The Raw Refraction Render Element is a color image that stores refraction information calculated from materials' refraction values in the scene. Surfaces with no refraction values set in their materials contain no information in the render element and, therefore, render black.

In comparison, the Refraction Filter Render Element is a render element that indicates varying degrees of refraction in the scene through brightness values in the image. Multiplying these two render elements together produces the Refraction Render Element.

Note: To properly calculate the Raw Refraction Render Element, the Refraction Render Element must also be added to the list of render elements so that all the refraction information in the scene can be determined.

How to add a render element to a scene


Enable Deep OutputSpecifies whether to include this render element in deep images.

Color Mapping – Applies the color mapping options specified in the Color Mapping rollout of the V-Ray tab in the Render Settings window to this render element. This option is enabled by default.

Consider for Anti-Aliasing – When enabled, anti-aliasing is used where possible.

Filtering –  Applies an image filter to this channel.

Derive Raw Channels – Generates data in the raw channels by combining the respective color and the filter color channels.

Vfb Color Corrections – Applies the post-render color adjustments made from the VFB.

Denoise – Enables the render element's denoising, provided the Denoiser render element is present.
