Mental Ray Light Fog Tutorial

Here is a tutorial I did on making light fog in mental ray. This is something I've wanted to do for a while, since light fog seemed to always be one of the few things mental ray couldn't do. However, I found out that mental ray can do light fog... it's just a little bit complicated. Overall, I didn't have too much trouble with the tutorial, I just had to tweak settings like the extinction, nonuniformness, and min and max step. It's not quite as simple as the maya software option of just clicking the create light fog button, but it does work and can be customized more than maya software light fog.
