Mist particle system effect

Started working on creating a "mist" effect for my honours project excuse the jumping bear (It made me laugh) as my frustration grew. It uses assets available from Unity's own packages and a few minor tweaks. 

I wanted to create a mist that would flow along streets during a night time setting so I decided upon using a "Edge" shape so that it billows forward.

I had a little issue trying to get the billboards to display correctly as for a while I had the below issue.

As you can see this is an issue for a character to walk around seeing texture tiles floating around... but if you make sure "simulation space" is set to local, set render mode to "Vertical Billboard" and finally set Pivot to 1 on the Z-axis you'll end up with a pretty haze just like how your parents remember the 70's.
