The background setting option requires the user to browse to an image file to be used for the background of a rendered image. The background can be a regular 2D image, Spherical image, Single Color, or From Environment. From this part of the library the user can select a suitable background image to use.
Background Spherical
Enables the user to select (*.hdr), (*.exr), or any image file, that will be wrapped around a sphere or hemisphere, and select color, size and brightness.
This option is added to give users more control since the Environment-HDR (global HDR) in the Render Settings dialog can be rotated, but cannot be scaled.
Select Environment at the top of the Object Tree, then select background in the Properties Dialog. In the Background tab select Spherical, then browse to a spherical *.png image, the user can also select and download one from the library.
Then by clicking the ‘+’ Add to background library button, the current image will be added to the library. A unique name should be given to each background image.
Clicking the add button in the any library, displays the Add New Item dialog. The name and preview image for the item can be entered and its preview image will be added to the library.
