Hey, thanks for your reply 🙂
What I meant was that because the foot (the extremity) is parented to the lower leg, it is rotating with the lower leg – there need to be a counter-rotation of the foot to compensate it.
Your solution in the article was to apply a transform effect, put the “anchorPoint” expression to both anchor and position properties of the effect, and another 2 lines expression to the rotation properties of the transform effect.
Now the problem is that when I apply the “anchorPoint” expression to the anchor/position of the transform effect, the rotation axis is in a weird place and the foot is separated from the lower leg. The counter-rotation expression works well, but the counter-rotation axis is in a wrong place.
I can attach a After effects file if that would be easier,
Thanks a lot Dan
