I have been trying to map an electrostatic potential to an electron density
of a molecule. Afterwards I want to render it. Since I cannot get POVRAY
3.6 to render the colours, I am using Tachyon. How do you get a transparent
background with Tachyon as you would with the POVRAY +UA command?

Thanking you in advance,
