This page provides information about Raw Diffuse Filter Color Channel in V-Ray for Houdini.
Overview
The Raw Diffuse Filter channel type is similar to the Diffuse channel, except it is not affected by Fresnel falloff. The result is a solid mask showing the pure diffuse color as set in the V-Ray Material's settings.
Attribute
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 Notes
The Raw Diffuse Filter Render Element is not very commonly used in compositing. It may be useful when used in conjunction with the Diffuse Channel, when pure black and white values are needed for a specific compositing job.
