I end up having to Google search the commands the relevant commands every time I need to make publication-quality figures in Pymol, so I’m just going to note them here to save myself some time.

1. set bg_rgb, white
   
   This sets the background to white. Usually safe bet for any image meant for a normal presentation (ie. slides with white backgrounds), or a publication (where it’s text and images against a white page).
   
   
2. set ray_trace_mode, 1
   
   This allows it to have the “black outline” representations, which I think look a little nicer than the default.
   
   
3. ray [Some number, usually between 900 and 1500]
   
   This makes a static fully-rendered image that is much higher quality than the fast render in the interactive interface.

See above for an example of what a resulting image looks like.
