Fog mutiplier - units

V-Ray V-Ray for 3ds Max General
1

I am going through the great joconnell tuturial about fog but I have a problem. I cannot set the fog multiplier to anything smaller then .001 if I try to go any lower say .0001 max rounds it up to 0. I downloaded the scene file for this tutorial and opens up already rounded out to 0.
I am using 7.5 and my scene unit are in centimeters. Does anybody know if this is a max or vray bug or setting.

Thanks as always.

Duh !

I figured it out but am replying just in case anybody else has the same problem. It was a setting in the in the General preferences - can’t believe I never knew this, so embarassing. Maybe I can save somebody else the hassle, now I have the setting sorted, fog renders sweet :lol:
