Total Light RE

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

Overview

The Total Light Render Element is a color image that includes the effects of both direct and indirect lighting on materials in the scene, including the diffuse component. It is a result of adding the Lighting and GI render elements or of multiplying the Raw Total Light and Diffuse render elements. See the example for a use case.

UI Path: ||V-Ray|| > Render Elements > Total Light

Properties

Enable Deep Output – Specifies 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.

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.

Compositing Examples

For a more precise composition, we can use Raw Total Light and Multiply it (i.e., set its Blend Mode to Multiply) by the Diffuse RE. Alternatively, we can combine (i.e., set the Blend Mode to Add) the Lighting RE with the GI RE to extract the diffuse component and tweak the lighting only.

Example: Light Adjustments

In this example, we've combined (Blend Mode set to Add) Lighting RE with the GI RE. This Render elements set is, in turn, brightened and warmed by adding Total Light RE and adjusting its multiplier and color. This approach does not extract Total Light at the beginning, as it uses an already-baked Total Light as a starting base and includes the Diffuse component.
Also, Refraction RE is added to compensate for the brightness behind the glass objects (the bulb and the toy) by tweaking the multiplier and warming the color.
