Starting at 9:45 or so he talks about using an Expression in the 'Offset Turbulence' to create a certain 'speed' of the water. He uses the Fractal Noise plug-in to make the water and the sky.
If(prevframe.valueAtTime < ((time * 25) % 2 = 0).valueAtTime))downColor else upColor Prevframe = thisComp.layer("Ctrl").effect("Slider Control")("Slider").valueAtTime(time - ameDuration) Value = thisComp.layer("Ctrl").effect("Slider Control")("Slider") UpColor = thisComp.layer("Ctrl").effect("Up Color")("Color") ĭownColor = thisComp.layer("Ctrl").effect("Down Color")("Color") so far I got this: (for the first part anyway) I want it to change value every few seconds and do it with a "hold interpolation" so it will jump to the next value instead of working it's way toward it. if it will goes up, then it will change to blue and if down then to orange (for example). There is usually a way to do what you want in AE if you think outside the box.I want to make an expression for a randomly changing number, (so far so good), but each time it will change a value, I want it to change color relatively to the previous value it had. If that happens you can add a stroke, then just turn the stroke off in the AE project. Sometimes AE is buggy creating shape layers from vector layers. Here's a zip file for you with both a CC and a CS6 project inside. If you use Trim Paths then you must have a straight tapered line and you have to set the right first vertex and then animate both start and end values to make the line start at the thinnest end and extend to the thickest end. If you use Offset Paths instead of Trim Paths then the line starts growing from the thinnest point and moves to the thinnest point. There are two ways to animate the creation of a tapered line. The way to do this is to start in Illustrator, create your tapered lines there, Expand appearance in Illustrator, then import as a comp in AE and convert vector layers to shapes.
