or V-Ray Curvature.

A common use for V-Ray ExtraTex is to

use V-Ray Dirt

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 V-Ray ExtraTex 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 V-Ray ExtraTex 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 V-Ray Object Properties > Matte/Shadow > Matte Properties

for the selected object(s).

The parameters for this render channel appear in the Parameters tab under the out Network and within the render elements node.

Name – The text added to the end of the rendered file, when saved as a separate file (e.g. myrender.ExtraTex.vrimg).

Texture – An input slot for a texture.

Exclude List – Specifies a set of objects to be excluded from the extraTex channel.

Exclude List As Inclusive Set – When enabled, V-Ray applies Extra Texture only to objects in the Exclude List. When disabled, V-Ray applies Extra Texture to all objects out of the Exclude List.

Denoise – Enables the render element's denoising, provided the V-Ray Denoiser render element is present.

Consider for Anti-Aliasing – When enabled, anti-aliasing is 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.

Force 32-bit Output – When enabled, stores the Extra Texture render element as a 32-bit float even when writing a 16-bit raw image. This option applies only to multichannel .exr files.

Force Lossless Compression – When enabled, forces lossless compression for this channel when DWAA/DWAB compression is used.

Deep Output – Specifies whether to include this render element in deep images.
