The Extra Texture Render Channel 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. A common use for ExtraTex 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 a similar result to the ExtraTex render channel 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 ExtraTex render channel provides a quick and easy way to render the scene with a single texture without the extra work. |
