Issue avatar 3.0 with hips and legs

Hello, I’m having issues with my avatars in 3.0.

Basically my right leg is going where the hips are ( I can see it with avatars 3.0 emulator control )
In-game the leg is going apart of the body. The avatar works propely in 2.0.
I tried to use avatars that works for other ppl in 3.0 and I always have this issue, I tried to create new project with the lastest SDK, still have the same issue…

Can anyone help me please ?

Thank you !

Got screenshots of the rig? Ideally from the front/side views in orthographic perspective in blender.

Usually stuff like this is caused by some rig oddities. This may be work checking over: https://docs.vrchat.com/docs/rig-requirements
