This page provides information about the Material ID Render Channel in V-Ray for Blender. Overview The Material ID Render Channel isolates objects with specific materials by Material ID for compositing purposes. This render channel provides a mask for individual objects and materials that is easy to select in compositing software. This render channel either shows each material (by Material ID) as a solid unshaded color or stores the Material IDs as integer values within the EXR format or VRay Image Format file.  The  Color (with Anti-Aliasing)  method supports antialiasing at the edges of objects where they meet other objects or the background. The  Integer (no Anti-Aliasing) method , which assigns a Material ID to each pixel in the render channel, does not support antialiasing as each pixel can have only a single Material ID assigned to it. More than one Material ID render channel can be used if desired, for example, if you wish to have both solid-shaded color and integer-based render channels for maximum flexibility during compositing. UI Path:  ||V-Ray Node Editor|| >  World  >  Render Channels  >  Matte  >  V-Ray Material ID Properties   See the  Render Channels  page to find out where you can find these properties. Channel Name  – Customizable name for the render channel. Enable Deep Output  –  Specifies whether to include this render channel in deep images. Color Mapping  –  Consider For Anti-Aliasing  – When enabled, anti-aliasing is used where possible. Filtering  –  Applies an image filter to this channel. Vfb Color Corrections  – Applies the post-render color adjustments made from the VFB. Denoise  – Enables the render channel's denoising, provided the  Denoiser  is enabled.
