ripples in fractal water?
Hey all. Had a question about my After Effects project. I used Andrew Kramer’s method for creating reflective and refractive water using fractal noise. You can see what I have so far here:

Anyways, my question is about the possibility of making ripples in the water as the croc floats along. I’m thinking that I have to distort the pre-composed fractal noise layer in some way. Any ideas? Also, if anyone has any constructive criticism for the piece, send it my way!p.s. huge HUGE thanks to both Andrew Kramer and Aharon Rabinowitz for their tutorials that helped me get this far with this animation.

You would want to use the Wave World effect on a solid to create the wake. Animate the Producer to match the motion of the Croc (this could potentially be simplified with an expression). You will need to set it to render a Height Map (the default is wireframe preview) and then lay this over your ‘fractal water’ with either the Overlay, Soft Light or Hard Light blend mode.
I wish I could give you more specifics, but the link you provided doesn’t seem to be working.

Thanks for the advice. I’ll look into it tonight. The link is working fine for me…any others having trouble viewing my work?

i was unable to see the file too… it may be that i didn’t wait long enough to download the movie, but after a couple minutes the progress bar hadn’t even started to move. you might try a smaller file. if you have a compression utility (compressor, squeeze, etc.) you might just drop it on that and set it to reduce the frame size and maybe the frame rate by half and kick out a flv or mpg.
but i think darby’s suggestion was good… you’ll need to modify the fractal noise comp with something to generate waves. and wave world is very good at that. you may also be able to just create a still in photoshop that is creates a wave or wake like shape then use blending modes (as darby mentioned) to mix it with the fractal noise. you could animate the movement of the wake with the movement of the croc if needed.
