Steps to reproduce the issue:

1. Export a character from Character Creator 4 using Full Base (do not check "Convert Scene").
2. Import it into Unreal Engine using the official CC Auto Setup plugin.
3. In UE, generate a Control Rig using CC UE Control Rig.
4. Drag the generated Blueprint into the level, or add it into Sequencer.

Actual Result:
The character mesh becomes completely distorted or twisted (see attached screenshots). This also happens with ActorCore characters.

Expected Result:
The character should remain properly posed, and the Control Rig should match the skeletal orientation regardless of whether "Convert Scene" was used.

Additional Notes:
The issue appears to be caused by incorrect Primary Axis or Pole Vector values inside the IKTwoBone node of the Control Rig. Manually correcting the axis settings fixes the pose, but this should be automatically handled by the plugin.

This causes confusion and workflow interruption for animators who skip "Convert Scene" to maintain original proportions or compatibility.

Please consider implementing an automatic axis adjustment or a user prompt when generating the rig, to avoid broken poses in future versions.
