Hello, I am using the Blender Auto Set Up. I did a character, then I used GoBlender and then Rigify. In Blender, I made an animation with the Rigify rig. Then i click "Sequence", in the cc/ic addon for blender, to send the animation to CC4. When I did it, although the animation seemed correct, I noticed that the arms were a little bit offseted in the 3d space. To make sure that I was right, I sent that CC4 animation back to Blender by clicking "Send Motion". After that, in Blender, I compared the two animations (the original i did before clicking "Sequence" and the one CC4 received from the link), and yes, positions of both hands, feets, even the hip were a little bit moved. Since I am doing a detailed hand animation with objects that the character picks up from a table, i need an accurate animation. It happens to all characters I do the process with. I hope you can help me.

This is 3 screenshots of the same frame (1) from the two animations:
Original:
 87% of original size (was 576x704) - Click to enlarge

The one sent to CC4:
87% of original size (was 576x704) - Click to enlarge

I have tried to send the second one to cc4 and then to blender and hands and feets keep moving down:
87% of original size (was 576x704) - Click to enlarge

This was a problem with the Rigify rig IK solver. Blender has an option to allow the bones to stretch (or compress) under the IK constraint and Rigify makes heavy use of it and the Rigify rig is very stretchy. As other platforms (CC/iC or anything else) don't allow the bones to stretch, the hands and feet can land in the wrong place.

So, when exporting or transferring Rigified animations the add-on will now disable all stretch in the IK solver constraints. The hands and feet should now land in the correct place, or at least much much closer. Something to note is that the elbow and knee joins may end up in slightly different positions as a result.
