Re: [PyMOL] Is exporting CGOs vertices possible?

[Nat E. <ec...@uc...>]

PyMOL will already dump POVRAY format files; you should be able to feed
these to Blender somehow.  This looks like it might be useful:

No idea if it will work well. . . but probably worth a try before writing
something yourself.
