The Background Render Element stores an image of the texture used in the background behind geometry in a scene as seen from the camera. Geometry that blocks the background image renders as black. This render element interprets a background texture, such as the texture set in the Environment Overrides, as a background. Other types of manually created backgrounds, such as a plane, mapped with a texture set outside a window, will not interpreted to be a "background" for the purposes of this render element. To use render elements, select from the Available render elements column and click the Add button to add the passes you wish to generate at render time. When you render the scene, the added render elements listed in the column on the right, will also render, which can be viewed from the VFB window's channel drop-down menu. For more information on the parameters on this dialog, see the Render Elements tab page. |
