    Hi!

    I’m making smoke following this tutorial but I wonder there’s any way to add randomness to its movement. I suppose there’s must be some expression or something like that but I have no idea about them so far.

    Interesting technique in that tutorial. And the first thing that sprung to mind was to use the included script (Window > Create Nulls from Paths) One of the options in there is the option for paths to follow nulls. You can then set up wiggles on the null positions.

    Alternatively, you could just use the Wiggle paths option, available on the tiny Add menu on the shape layer.
