Problem with Dan Hebert’s Inverse Kinematic expression
I read and im am using Dan Ebbert’s expression on inverse kinematics.EXELLENT, very nice, very smooth, lot of control and a very ease to follow tutorial even for a beast like me. But i have a problem, let’s asume that my character is dancing, when his feet touch the ground how can i make them stay in the surface instead of going through it. The movement is nice, but i am having a lot of trouble with this, can it be fixed by an expression ?. Anyway, i am very thankful for the knowledge you are sharing and the way you are doing it, it’s a great work.

Do you meant that the feet don’t stay put when you move the torso (because you have the effectors parented to the torso)?
Or do you mean that the feet, when planted on the floor, rotate at the ankle (as you move the torso around) so that the toes dip below the level of the floor?

I have the extremities all parent to the torso so when the character jump i move it by the torso and animate the efectors so the tip of the toe lands first. But i found very hard to do the whole movement coherent, the bending of the ankle and the tip staying in place it has to be done almost frame by frame because the movement of the rest of the leg changes the position continuously. The character changes the lean point by the two legs and the hands, so i have the same problem with each extremity. It seems absurd to me that After Effects being on of the most complete 2d software doesn’t have an plug-in or asistant to simulate a bone system to animate properly. Thanks for your time again !!

I’m worried that the question is not clear. Is there any way to have more control over the tip of the extremities by an expression? The postition of the feets and hads seems to be subordinate at the movement of the leg, it looks like the point of lean is the tip of the leg and not the feet. Could be possible that the feet is positioned in a very stable point and the leg bend itself by the movement of the torso ? That could be great !!. Anyway i am very grateful for your expression and it really does the work, without it i would be in the wild. Is just that i have to animate this character a lot and in a very complex way, so i will like to have the most of control before i start animating. Can this be done by expressions ?
