This page provides information on the Extra Texture rollout in the Render Elements.


Overview

The Extra Texture Render Element renders the entire scene with one texture mapped onto all objects in the scene. The texture applied to the scene can be a bitmap or a procedural texture such as Dirt or Curvature.

A common use for the Extra Texture is to use 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 you can obtain a result similar to the Extra Texture render element by applying the same texture to all objects in the scene and rendering as usual, such an approach requires additional time spent on reverting to actual materials, saving different versions of the scene, etc. The Extra Texture render element provides you with a quick and easy way to render the scene with a single texture without the extra work.

Parameters

Texture – Specifies the texture to apply to all scene surfaces in this channel.

Denoise – Specifies whether to denoise this render element.

Affect Matte Objects – Specifies whether to include matte objects when generating the render element. A matte object is an object that has been assigned a Wrapper Material or VRayObjectProperties with the Matte surface option enabled.

Consider for AA – When enabled, anti-aliasing is used where possible.




Compositing



The Extra Texture Render Element is useful for changing the appearance of a render in a compositing or image editing software. The example formula uses a Dirt texture with its Radius parameter set to 100cm and Subdivs set to 6. The Extra Texture is blended using Multiply mode.






Footnote

  • The Extra Texture UV size is permanently set to 1 by 1 inch as it utilizes the default Rhino texture size. To control the appearance of the render element, adjust the slotted texture's placement parameters.
