Is it possible to apply joint corrective blendshapes automatically?

Hi,
thank you very much for your support request.

There is currently no way to build a custom property controller that drives multiple channels at the same time (in your case the rotation of the elbow and the blend shape weight). You could either adjust the blend shape manually according to the current rotation value or you could write your own driver script that does that for you.

For the scripting approach, add a new MonoBehaviour to one of the transforms of your GameObject that looks something like that:

public class ElbowMorphDriver : MonoBehaviour

{

   public float InputValue = 0f; // Access this property via a "Custom Property" constraint from UMotion

   [SerializeField]private Transform ElbowJoint;

   [SerializeField]private SkinnedMeshRenderer BlendShapeSmr;

   // This method is going to be called every time UMotion re-calculates the current pose.

   public void UMotionCallback() // Let UMotion call this method (enter callback name at Pose Editor --> Options -->

                                                   // Extending UMotion --> Callback Name; check out manual by clicking on the black info button)

   {

      // According to the InputValue, set elbow joint rotation and blend shape weight

   }

}

Please let me know in case you have any follow-up questions.

Best regards,
Peter
