Solid Background is an addon for Blender that introduces a solid color background to the World shader without altering existing node setups. It adds a non-destructive node network to the current configuration.

The tool is accessible through the N-Panel or via right-click within the Shading workspace. It provides a straightforward method for setting a stylized background or toggling the Film Transparent option directly from its interface, streamlining look dev and product render setups.
