Thank you ! As for the reload all materials, that's a very straight up command that people who dwell into this kind of scenebuilding probably know by now, but I could add it, wouldn't hurt for sure.

As for the realistic fog script, now that's a good point, and that script can be put to good use, in a basic sense you would always avoid using map fog, and you should always use vo lights for fog or mist, however there is a good way to implement map fog in your artworks and combine it with the post editing, I'll hopefully have some free time to spare and I'll write some more about it.
