Quest 3 Full body tracking and ReadyPlayerMe Avatar Problems...?

Hello Everyone,

I want to use full body tracking (IOBT) in Quest 3 with ReadyPlayerMe characters. But it has some weird problem with the back(As in the pictures). Can someone please help me solve this? I tried editing the avatar but was not helpful at all.

The settings I am using is setup the characters in the scene with Movement > setup character with Body tracking > Formant: Unity Humanoid.

then selecting Full body on “OVRBody” and “OVRUnityHumanoidSkeletonRetargeter” both.

the body tracking works perfectly but the back(of the character) of it is broken.

Modify the humanoid and check the bones there to see if they are mapped right

I tried it already and its not working.

I tried editing the Avatar, and the skeleton as well.

I have Solved it by un assigning the Bones in the avatar, It worked.
