Rigged FBX file, has issues in unity and works fine in Maya or unreal.

Hi,

I'm working on a project where the mesh of my 3D character is malformed once it enters unity. I've tested this in unreal but there it seems to be working fine. Don't know what's happening or what unity does wrong when importing this file.

The character has a rig and on that rig we created several animations, that seem to all work fine however the conversion of the rig from fbx in unity seems to do something wrong in unity.

I would be so greatfull if someone could help me on this.
