ue ik rig bone limit not work when ik retarget

in ue5.3, IK Rig set up the bone limit(every joint only rotate on certain axes and certian range), and then create retargeter, but ik bone limit not work correct


this is my source ik rig, its skeletal is standard human mesh,


this is my target ik rig, it is humanoid robot, its every bone just rotate only on certain axes and in certain range, and its skeleton structure is very different from human.

I have tried to debug a lot of parameters, and the final redirection is not good。

Hello!
