FK to IK conversion twists skin

Elsiehar 3 years ago • updated by Peter - Soxware Developer 3 years ago • 1

When I use the Edit/FK to IK conversion it twists the skin of my character.  See the right hand below.

Before conversion

After conversion

Image 691

I have tried to fix this by adjusting hand rotation, and elbow position and rotation (although the rotation doesn't seem to do anything?) and nothing works.

Any help would be appreciated.

Thanks

Hi Elsiehar,

thank you very much for your support request.

This might be an issue with how the IK is setup. Please try the following:

  1. Creat a new UMotion project
  2. Assign your character
  3. Open config mode and make sure that your character is in a T-Pose (standing straight, both arms stretched to the side). If it is not, you might want to try pressing the "Apply Bind Pose" button. If that doesn't help either, you can also manually rotate the bones. Once you fixed the pose, click on the "Save Reference Pose" button. For more information about config mode, see this video tutorial).
  4. Execute the IK setup wizard.
  5. Import your animation and convert it to IK again.

Does this fix your issue? If not, please send me your character, the animation you are importing and the related umotion project file as a *.unitypackage via the email support form (or request a link to my dropbox via said email form if file size is too big). That way I can make further investigations.

Best regards,
Peter
