This page gives some basic details about the Raw Total Light Render Element and explains how it is used in compositing.


Overview

The Raw Total Light Render Element is the sum of all raw light (both direct and indirect) in the scene, without any diffuse details.

This pass is useful for changing the appearance of the scene's light in a compositing or image editing application.



Attributes

The parameters for this render element appear in the V-Ray RenderChannelColor render channels node.

Deep Output – Specifies whether to include this render element in deep images.

Color Mapping – When enabled, the Color Mapping options in the render settings are applied to the current render channel.

Consider For AA – When enabled, anti-aliasing is used where possible.

Filtering – Applies the image filter to this channel. Image filter settings are in the Image Sampler tab of the Sampler tab of the V-Ray Renderer node.

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

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.


This render element is not supported with V-Ray GPU rendering.


Common uses

The Raw Total Light Render Element is useful for changing the appearance of the entire lighting of the scene after rendering, using a compositing or image editing application. A V-Ray Cryptomatte Render Element is used to isolate the floor, the windows along with the curtains and the stone fence, and the ceiling. Then the Raw Total Light Render Element is brightened and tinted differently for each element to show the range of editing possibilities. See the render before and after compositing.
