I wrote a little script a few years back. It was working in SI 2011.5, and should work in later as well.
Just select some keys in animation editor and run the script a few times :) (if you want to resample the curve as well. just uncomment the "oCurve.Resample.." line) Play with the last line with math.random function - the values there or read about random library on some python manual :) It may be very light change or very large - it depends on what the original values are. Remember to save Your work before running the script, just for backup. ###PYTHON SCRIPT ###BEGIN HERE import math import random xsi = Application oCurves = xsi.FCurveSelection for oCurve in oCurves: oKeys = oCurve.SelectedKeys cntKeys = oKeys.Count if cntKeys > 0: tmp = 0 for oKey in oKeys: if oKey.Selected == 1: if tmp == 0: fKey = oCurve.GetKeyFrame(oKey.index) tmp = tmp + 1 lKey = oCurve.GetKeyFrame(oKey.index) firstKey = math.floor(fKey) lastKey = math.ceil(lKey) # oCurve.Resample(firstKey, lastKey, 2.0) #uncomment this line to apply resampling between first and last key selected. KeysCollection = oCurve.GetKeysBetween(firstKey, lastKey) for oKeyz in KeysCollection: keyNow = oKeyz.index # move key by random number oKeyz.Value += (random.random() - 0.5 ) * 0.3 #change this values or use a different random - it will depend on what the original values are ###END HERE On Fri, Feb 14, 2014 at 2:48 PM, Rob Wuijster <r...@casema.nl> wrote: > Hi all, > > I ran into this before, but never really found a quick and dirty solution. > > What I'm after is to select a bunch of equal keyframes in the Animation > Editor, and randomize them in time. > e.g. 20 objects going from left to right, frame 1 to 100.
