It's a simple problem but one I can't seem to get my head round. I'm using a noise modifier which seems to perfectly mimic a realistic rotation of some equipment I'm deploying. My problem is I need to restrict this twice.

1 start noise at 3000 and end at 3400

2 start again at 4400 and terminate at 5000

I thought about key framing the strength but I can't add any keyframes to the noise panel

Basically I want the F-curve to look like it would do if the lime green line was added

enter image description here

Thanks for any help Sean

  • $\begingroup$ I edited the title to make it define what exactly is desired from the modifier. Unfortunately I couldn't find related questions for this one so not to answer here. $\endgroup$ – Mr Zak May 19 '17 at 15:45

One way to let the F-Curve modifier affect the animation in several frame ranges is to setup several F-Curve modifiers. So one modifier will be responsible for the 1-st frame range, another one - for the second and so on.


You can copy / paste modifiers with buttons in the top part of the Modifiers tab in the Properties region of the Graph Editor. Once modifier was copied change its frame range to make it affect another part of animation.
