Re: [script] Creating relative values fcurve

["Bernard Lebel" <3dbernard(at)gmail.com>]

Your script works perfectly, Kim. For "typlical" fcurves (that is, on transformations) I never had a problem creating those by script. But now I'm trying to create the fcurve of a link with _expression_ that connects the shapes (in the mixer) with cpset parameters.


Below is a script that re-produces my problem. The first part does like when I create the relative values manually. The second parts uses the SetKeys() method. The third one is the for loop we've been trying.

With second and last approach I'm getting exactly the same results. The first keyframe is 0/0, and the second one is 0.24/6.


Cheers
Bernard
