Ok so I'm rendering this scene at the moment, kind of a Swiss chocolate box scene, mountains, lots of trees, lake and (this is the killer) wouldn't it be nice to have a real thin layer of mist lying over the lake. So now the render has to calculate the mountains and trees reflecting through the mist onto the lake and back again. A render that used to take a few hours (pre mist) is now up to 26 hours and only a third of the way through. Considering that my foreground is all well above the mist/lake layer would it be faster to stop the render once these have been covered and re-render the foreground with the mist/lake disabled or will their influence be not be impacting on the foreground part of the render time since they are not visible?
