Issue 7645
Jittery Feet on UE FBX Export
Example:

1. Create a simple idle animation on any character, locking the feet using reach Effector.
2. Zoom in on the feet in IClone and verify that they do not move.
3. Bake the reach keys.
4. Export as FBX (UE Preset)
5. Import FBX into any 3D Application

Actual Result: Feet are clearly jittery and not locked in place

Expected Result: Feet would be locked, as they appear in IClone

I have spoken with a very experienced user on the forum and he verified that he sees this as well.

Hi,
This issue is caused by:

Reach Effector Group is under the "Hip" , so "Hip" animation will affect the Effector Dummy Group. 
Export FBX will re-sample the animation data, so Jittery Feet issue will be more obvious when exporting FBX.
That's current iClone 7 animation core design, and team is discussing this animation core topic, please wait for our follow-up update plan.

Workaround: 
Detach "Effector Dummy Group" before Bake Reach Key, you can get more good result. (see the attached video)

* Left one: workflow as you mentioned (Dummy Group is still attached to character)
* Right one: Detach Dummy Group > Timeline Bake Reach Key 

Please let us know if this workaround solved this issue or not, thank you~
