Humanoid avatar moves strangely in mirror mode

I have to use the mirror mode, but the moment I activate the mirror, the position of my arm moves in reverse as shown in the attached picture.

I raise my arm, but my avatar points his hand down.
I am wondering how to solve it.

I’m used orbbec astra+ camera.

Hi, have you tried basic avatar example from https://github.com/3DiVi/nuitrack-sdk/blob/master/doc/Unity_Avatar_Animation.md ?
One possible reason for this is that you are too close to the camera, so the hands aren’t visible and are being set to the default pose/position. The best option is to re-check in AllModulesScene (with explicit depth frame visualization) from the official Unity Package.

@wt.choi also you can check “RiggedModel” scene
