-ambient_factor XX
Is the command line, goes in custom flags.
I had a fiddle around with it, but using the env mapping / ambient lighting, all I see is problems and things...
Looks absolutely beautiful when it works...
Sadly once in a bluemoon though...
Examples of problems with ambient lighting on my 9600 Pro.

(The problem is actually not very obvious in this shot, since, you could actually believe a star is red enough to do this, but uhm...
Since (while you can see some pink around the edges of the star to say "ahh.....it's a red star", it's white, and therefore looks really odd when it makes ships look THIS RED), it's the angle the light seems to reflect at, it's kinda weird...not like you're seeing light bouncing off a ship, more like you're seeing a hologram fading in and out between the two pictures it normally has ...).
http://smalltimerivalry.com/sschost/scriptquantumdelta/FS2SCP/screen02.jpgLove the new paint job on the INSIDE of the Arcadia? A piece of that station that most definately is not exposed to the sun it's reflecting light from (You can tell the position of the star from;
A) the fact that the other panels next to it aren't reflecting anything...cuz.... that would just make sense if there was a gradient reflection...
B) The reflection of the stars light on the top of the arcadia, which is actually more or less correct.)
Anyway
I'm not 100% sure on how the numbers relate to the brightness, I've been scrolling through, I think, at this point in time the higher the number the darker your models will be.
....Since I can't see artimes (Non-DH

) on 75 heh.
Please note;
I really attribute env mapping and ambient lighting to eachother, because they don't work very well without eachother.
