View Full Version : [Q] Adding noise to animation curves...

I'm not really sure how to go about approaching this, so I thought I'd shoot off the question here.

Say I had a sphere translating up and then down 3 units in Y over 20 frames using 3 keyes (0,10,20) on X Y and Z... Is there a way to add noise directly to the resulting animation curves without setting a whole mess of in-between keys? Maybe using an auxillary node or a shader? I'm not really looking for an expression or dynamic driven soloution.

Ideally, the result I'd be looking for would be a slight wavering as it translated...but I'm willing to settle for an extreme example that pointed me in a direction I could experiment with. Any ideas?

A quickie would be:

Group your object,

for the group, this expression (or something similar)

group.ty=noise(frame)*$whatever

(where $whatever is a custom attribute to act as a multiplier for your effect which you can scale)

If you are interested in having a look at the motion graph (or getting the keys for that matter)
Then in the graph editor choose the groups translateY attribtute and then > show results
You can also bake the results, and convert them to keys where you can sample every 5, 10 frames, not every frame, as you like.

Hope this helps.

Thanks for the reply BigSky. That's pretty much the result I was aiming for, but not the method. Let me first say that this is not for a project or anything, it's merely an idea I was just wondering about... so the outcome isn't really the focus. As I wrote in my first post, I was mainly wondering if the animation curves could be affected by something like a ramp or fractal node vice using an expression.

Not sure it is allowed but, anyway...

Check this thread: I guess it would be useful for this matter.

trthing, thankyou. That is exactly the kind of thing I was looking for.
