This page provides information about the Unclamped Color render channel in V-Ray for Houdini.
Overview
The Unclamped Color Render Channel is a color image that shows the original colors that were clamped or adjusted with Color Mapping. This render element is useful in the compositing process for enhancing extreme colors (very bright or very dark) or for shading the final image with the unclamped colors.
When Color Mapping is used, the values that are clamped depend on whether the Clamp Output option has been enabled, as well as the rest of the Color Mapping parameters.
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.
Usage Example
The Unclamped Color Render Element is useful for revealing the true values of clamped colors and editing their look in a compositing or editing software. See the render before and after compositing.
