Overview

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 textures as the background; other types of manually created backgrounds, such as a plane object mapped with a texture set outside a window, will not interpreted to be the "background" for the purposes of this render element.

Notes

When the background is behind a transparent or semi-transparent material such as glass or clear plastic, make sure the Alpha channel is enabled for the material for all render elements; otherwise, the background will not be visible in the render element. For example, when using VRayMtl for a glass material, set the Affect channels parameter for both Reflection and Refraction to All channels to cause the background to appear in the Background Render Element behind the glass.
