Baking sim Amature into clothes error distortion

Hi. First, I don't remember if i've ever told you that, but it would be easier to adjust the rig that comes with the jacket to match that of ts4 ( that of course if the jacket comes with the rig). You just adjust it, apply and that's all. You can delete it.

Second, please always share the blend file that you imported in the package, not at any other stage of the process of adaptation. I cannot tell what exactly you did wrong because the jacket is not adapted in the shared blend file at all.

Okay, say, your jacket comes without the rig.
1). adjust the rig to the shape of the jacket and make it a rest pose;
2). transfer the data to the jacket from the body;
3). bring back the rig to its original pose, make it the rest pose
