Why is my Mental Ray fog so dark?
I'm finally trying out the "fog" atmosphere effect in Mental Ray and can't figure out why a white fog looks 50% grey in my scene.
Light: MR Sun (part of Daylight system)
Environment Map: mr Physical Sky
Atmosphere effect: Fog (regular)
Logarithmic Exposure Control: Active
- Color set to WHITE
No color map or opacity map
"Exponential" box unchecked.
Here is a WIP scene:
Any insights? Thanks.

looks correct to me, im guessing your sky is grey? thats what the fog is multiplied against... grey multiplied by white is grey... yes? Can you should us your Sky with the fog disabled for comparison?
Can I ask why you are using Mental Ray? I only ask because if you want to practice with this render engine you realize you will have to pay for it eventually - if you upgrade 3dsmax. This is offtopic but just something to be aware of

I'm guessing it has something to do with the exposure control. If that's the case, you may need to overdrive the value of the fog color above 1.0, if that's possible.
