    Hi!

    I’m using Fracal Noise to generate an animated background, I used the random grid motion expression from Mr. Ebberts site to animate the turbulence offset but I would like to link the evolution to this movement so that the fract evolves only during the movement phase. I’m able to connect it to one of the axis (vertical or horizontal) but I’m missing half of the fun since the evolution reacts half of the time only.
    Any tips?

    Thanks!

    You might try something like this:

    effect(“Fractal Noise”)(“Offset Turbulence”)[0] + effect(“Fractal Noise”)(“Offset Turbulence”)[1]

    I was looking at that this morning (Oz time) and can’t believe how simple the answer is 😛
    Nice one Dan.
