naturalistic light fog decay

[draykinm]

I'm using mental ray in maya with final gather. I'm using a spotlight. I've adjusted the fog spread, decay, density, and drop off, but none of that gives me a natural decay.

is your spotlight scaled enough to cover the entire room?

I agree, it looks like your light fog is cutting off very suddenly. Try scaling your light until the fog object fills the entire width of the room.

thanks for the help. I scaled the light, but the decay
