I am trying to extract the position and rotation from a packed objects rbd simulation.
It works for position but fails for rotation ( I did quaternion -> euler transformation from packedfulltransform )
Maybe someone could someone can give me a hint. I am kind of stuck ..
Is there nothing to make quaternion -> euler easier in wrangle ?

you can just use cracktransform() to extract rotation from transform matrix

The obtained rot attributes are found in the chop that their values vary greatly before and after frames. What if we can get a smoother one?
