This page provides details about the Atmosphere Render Element and how it is used in compositing.
Overview
The Atmosphere Render Element stores only atmospheric or volumetric participating media such as Environment Fog or Aerial Perspective. This render element can then be used to enhance or color-correct just the atmospheric component of the image during the compositing process.
When atmospheric effects or fog is included in a scene, they will render into the Beauty (RGB color) channel, and should also be output as the atmosphere channel for compositing use.
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.
Common Uses
The Atmosphere Render Element is useful for changing the appearance of the atmosphere and volumetric effects in a rendered image using compositing or image editing software. In the example, fog is generated using the V-Ray EnvironmentFog. The fog is assigned a warmer color and the intensity is increased, using the Atmosphere RE.
Compositing Formula
The V-Ray Atmosphere Render Element is added to the Beauty render to form the final image.
