This page provides information about the Light Select Render Element in V-Ray for Cinema 4D.
Overview
The Light Select Render Element represents the lighting contribution from a list of selected lights. It can output their direct contribution (in Raw, Diffuse, Specular or normal Illumination mode) or their Full effect on the scene illumination (including GI, SSS, reflection, refraction, etc). Multiple Light Select elements can be rendered for a single scene, and lights may be included in more than one Light Select element. However, a good practice is to have one Light Select element for each light source in your scene. This way, specific lights in the result render can be adjusted (color, temperature, brightness, etc.), while compositing without the need of re-render.
For example, by generating a Light Select element for all of the backlights in a scene, an artist may adjust the backlighting of the rendered scene easily in the composite without affecting the rest of the scene's illumination.
Options
Enable Deep Output – Specifies whether to include this render element in deep images.
Color Mapping – Applies the color mapping options specified in the Color mapping rollout of the V-Ray tab in the Render Settings window to this render element. This option is enabled by default.
Consider for Aa – When enabled, anti-aliasing is used where possible.
Filtering – Applies an image filter to this channel.
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.
Denoise – Enables the render element's denoising, provided the Denoiser render element is present.
Mode – Sets what type of lighting contribution is generated in the element as follows:
Direct illumination – Contains diffuse and specular information from the specified lights.
Direct raw – Lighting within the VRayLightSelect element behaves as a raw render element.
Direct diffuse – Lights output only their diffuse contribution and contain no specular information.
Direct specular – Lights output only their specular contribution and contain no diffuse information.
Full – Lights provide full output for all information available in the scene such as GI, SSS, reflection, refraction, etc.
Indirect – Lights output only the indirect scene lighting.
Indirect diffuse – Lights output only indirect scene lighting that originated from the diffuse contribution of the specified lights.
Indirect specular – Lights output indirect scene lighting that originated from the specular contribution of the specified lights.
Subsurface –
Light Path Expression – Allows capturing custom light transport paths with regular expressions.
Light Path Expression – Allows you to enter a Light Path Expression when the Mode is set to Light Path Expression.
Include Children –
