View Full Version : Strange Anim curve interpol bug (sync Quaternion)

Hi,

I have a problem with some of my anim curves created by importing animation data.
The angles are stored in Quaternion's and I setup the curve to interpol as Synchronized Quaternions which works fine.

But some joints have a strange bug that appears not very often say 1 out of 50 animations and the problem will only be on 1-2 joints in that animation that typically has ~100 joints.

If I import the anim then save the scene as a .mb then reopen it sometimes it fixes itself but not always.

Same scene & animation but different joint and it has no problems:

Anyone got any idea's?

Thanks, Tom.

You should be able to get rid of the discontinuities by applying a Euler filter.
You can find it in the graph editor.

I try that and it did nothing. :curious:

I set interpol with the following cmd for each curve when it's imported.


rotationInterpolation -c quaternion // xyz etc..


thx for the reply :)
