This page gives some basic details about the Custom Color Render Element and how it is used in compositing.
Overview
The Custom Color Render Element is a generic render element container used for referencing other render elements of type RenderChannelColor containing color information.
UI Path: ||Display Render Settings button|| > Render Elements tab > Custom Color
To use render elements, select from the Available render elements column and click the Add button to add the passes you wish to generate at render time. When you render the scene, the added render elements listed in the column on the right, will also render, which can be viewed from the VFB window's channel drop-down menu.
For more information on the parameters on this dialog, see the Render Elements tab page.
Attributes
The parameters for this render element appear in the Attribute Editor under Extra V-Ray Attributes.
Enable – When enabled, the render element appears in the V-Ray Virtual Frame Buffer.
Deep output – Specifies whether to include this render element in deep images.
Alias – Specifies an identifier for the render element. This can also be used to reference other render elements through their Vray Alias [vrayRE] attribute (found in Extra Attributes rollout; not the cleaner Extra VRay Attributes rollout).
Name – The text added to the end of the rendered file, when saved as a separate file (e.g. myrender.custome_color.vrimg).
Apply color mapping – Applies the color mapping options specified in the Color mapping rollout of the VRay tab in the Render Settings window to this render element. This option is enabled by default.
Filtering – Applies the image filter to this channel. Image filter settings are in the Image Sampler rollout in the VRay tab of the Render Settings.
Denoise – Enables the render element's denoising, provided the Denoiser render element is present.
This render element is not supported with V-Ray GPU rendering.
