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 and 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).

Bump Normals and World Positions Render Elements are is useful for changing the appearance of lighting in a scene in a composite without the need for re-rendering. The example below is a lighting workflow that is used at a composite level to change the lighting in the scene. Note that it does not create any extra shadowing or GI. While the Bump Normal Render Element provides information about how lights will affect each surface; the Point Position element passes the spacial location of each pixel. When used together it allows lights added in composite to react on the pixels as if they were the surface of the model.
