3d vertex noise interpolation

dust's picture

so i am wondering if there is a way to slow down the kineme 3d noise patch but still have it update continuously ? basically i have a 3d animation of a willow tree, i made in maya with leafs blowing in the wind. i wand to slow down the noise i added to the leafs, maybe interpolate quadratic style. it seems the noise patch is at a constant linear rate and the amount seems to just adjust well the amount of vertex displacement. anybody have any suggestions. im attaching a picture and the file so you see what im talking about.

Re: 3d vertex noise interpolation

There's no way to slow down the noise -- it has infinite frequency, so stepping through at any speed will be just as "noisy".

What you want to do is use noise exactly once, and then use the blend patch to blend between the non-noise one, and the noisy one, and modulate the blend amount to get smooth "noise".

brilliant thanks chris. i will check out blend shapes today.

so i added just a tiny bit of feed back to give this some motion blur and the leaves where looking really good, but the blend-shaping made all the difference when timed to the undulation of the fake wind. so it is feeling natural now or much more so than before thanks for the suggestion. this pic doesn't do it justice but you can see how some feedback can give you a decent motion blur.
