These are a bunch of Environment fog tests created from a tutorial by Alan from last year. The next step will be to attempt some sort of animation. This tutorial is pretty useful because not only does it show how to create fog but because of the eggs it gives you the opportunity to see how objects then react with it. The top one is the base tutorial and the other three are the tweaked ones. I quite like the third one with the less intense fog (created by changing the colour rather than density and opacity) and the glow on the eggs. The fourth one is an attempt as making fog that sits above the ground, intensified for dramatic effect.
