This page provides information on the Extra Texture render channel.
The Extra Texture Render Element shows the rendered image with a single texture applied to all objects in the scene. The texture applied to the scene can be a bitmap or a procedural texture such as VRayDirt or VRayCurvature .
A common use for VRayExtraTex is to use VRayDirt as the texture, which creates an ambient occlusion element for use in the composite. In this way, ambient occlusion can be controlled separately during the compositing process.
While a similar result to the VRayExtraTex render element can be obtained by applying the same texture to all objects in the scene then rendering as usual, such an approach requires additional time spent on reverting to actual materials, saving different versions of the scene, etc. The VRayExtraTex render element provides a quick and easy way to render the scene with a single texture without the extra work.
Note: Specific objects can be excluded from this Render Element by disabling the Generate Render Elements option in the VRayObjectProperties node for the selected object(s).

The parameters for this render channel appear in the Parameters tab under the out Network and within the render channels node.
Name – The text added to the end of the rendered file, when saved as a separate file (e.g. myrender.ExtraTex.vrimg).
Denoise – Enables the render element's denoising, provided the Denoiser render element is present.
Consider for Anti-Aliasing – When enabled, anti-aliasing will be used where possible.
Filtering – Applies the image filter to this channel. Image filter settings are in the AA sub-tab of the Sampler tab of the V-Ray Renderer node.
Affect Matte Objects – Sets whether to include matte objects when generating the render channel. A matte object is an object that has been assigned a Wrapper Material or has the Matte surface option of the Object Properties enabled.
