Ray opaque background

Overview

This setting changes how PyMol treats the background. If this option is ON then the background is whatever you specify -- like black or white; however, if the setting is OFF, then the background will be treated as a transparent alpha channel.

Settings

set ray_opaque_background, off   # turn on transparent alpha channel

Examples

• 

  Ray Opaque BG=0; blank white background; transparent background with the checkerboard beneath it.

• 

  Ray Opaque BG=1; notice the checkerboard not visible.
