How to create Mist in Blender I already tried several ways to create Mist in Blender, but it never worked 100%. I use Blender 2.78 and I want to create Mist like in this scene here. 
What are the exact steps? 



Here is what I have tried so far:

I already tried this: http://blog.yamandi.com/mist-pass-blender-268-how-use-it-cycles but it simply did not work .. I dont know why.

(EDIT: I managed to fix it: Check out this graphic: 

Until now I already used objects successfully as Mist-creators (Volume Scatter under Volume Material). The bad thing about using Objects as Mist-creator is that they dont have an endless mist range + the mist can not be bright. Normally it appears grayish result is bad..

Indeed, you should connect the composite node to the output of the node tree, otherwise it won't work -- that's a mistake in the tutorial.

If you want to change the mist colour, place a ColorRamp node in between, and change the colour of the right-most point.
