The Self Illumination Render Element stores the illumination of any self-illuminated materials in the scene.
Overview
The Self Illumination Render Element isolates self-illuminated materials, including V-Ray Mesh Lights, objects with the V-Ray BRDFLight, and any objects with Self-Illumination enabled in their V-Ray material. This render element is useful for brightening or color-correcting self-illuminated materials in the final composite.
For example, the V-Ray Material has a parameter for self-illumination. If this parameter is set to a non-black color value, this render element shows the results of the self-illumination.
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 Self Illumination Render Element is useful for changing the appearance of self-illuminated surfaces after rendering in compositing or image editing software. See below the render before and after compositing.
Compositing Formula
Self Illumination + Beauty = Final Image
Notes
- This element contains only the light geometry itself, not the light emitted from it. Lighting information is contained in the Lighting Render Elements.
