Hello.  I was advised by Reallusion support to post my question in this forum.  I'm having some diffuculty getting an exported Character Creator 3 model to work with Unity through mechanim.

I've followed tutorials and worked with both asset store animations and mixamo animations.  Both animations and CC3 rig are set to humanoid.  It seems as though something is off wherein the bones are "tilted" at the hip, and I'm just not smart enough to figure out what's going on.  It was such a basic import that I'm lost as to what could be occurring.  Any ideas?

Hello. Don't know if you've solved your problem….

It looks like you have some IK working on your figure. Is it possible the pelvis is mis-aligned by the IK?
The feet and hands appear to be held in the correct position by their IK points, so the pelvis IK being offset might account for the hunched over posture.

Hello, I have the similar issue and did not find any workaround.
Please can someone pin this and help?
