Unity 5.5 IK problem.

Hello there, I have been working on a custom climbing system in unity 5.5, but I think that I found out a bug in unity 5.5, I am sure if it is there in other unity versions, but I am currently using the latest version of unity.

Code (CSharp):

1.                 PlayerAnimator.SetIKPositionWeight(AvatarIKGoal.RightHand, Therload);
2.                 PlayerAnimator.SetIKRotationWeight(AvatarIKGoal.RightHand, Therload);
3.                 PlayerAnimator.SetIKPosition(AvatarIKGoal.RightHand, ActionStairs.Stairs[CurrentStairsIndex].GetComponent<StairBarInfo>().RightHandPosition.transform.position);
4.                 PlayerAnimator.SetIKRotation(AvatarIKGoal.RightHand, ActionStairs.Stairs[CurrentStairsIndex].GetComponent<StairBarInfo>().RightHandPosition.transform.rotation);
5.                 PlayerAnimator.SetIKHintPosition(AvatarIKHint.RightElbow, PlayerControl.RightElbowOffsetClimb.transform.position);
6.                 PlayerAnimator.SetIKHintPositionWeight(AvatarIKHint.RightElbow, 1f);

This is my current code, it works perfectly fine , but the RightElbow is not moving no matter what I do. so the "RightElbow" is not moving when I am using "RightHand" in SetIKPosition, here is what I tried and it worked perfectly:

Code (CSharp):

1.                 PlayerAnimator.SetIKPositionWeight(AvatarIKGoal.RightHand, Therload);
2.                 PlayerAnimator.SetIKRotationWeight(AvatarIKGoal.RightHand, Therload);
3.                 PlayerAnimator.SetIKPosition(AvatarIKGoal.RightHand, ActionStairs.Stairs[CurrentStairsIndex].GetComponent<StairBarInfo>().RightHandPosition.transform.position);
4.                 PlayerAnimator.SetIKRotation(AvatarIKGoal.RightHand, ActionStairs.Stairs[CurrentStairsIndex].GetComponent<StairBarInfo>().RightHandPosition.transform.rotation);
5.                 PlayerAnimator.SetIKHintPosition(AvatarIKHint.LeftElbow, PlayerControl.RightElbowOffsetClimb.transform.position);
6.                 PlayerAnimator.SetIKHintPositionWeight(AvatarIKHint.LeftElbow, 1f);

I noticed that the "LeftElbow" is corrisponding fine to the "RightElbowOffsetClimb" object position, but the "RightElbow" together with "RightHand" doesn't work at all, I tried to change the order but the problem presists.

 

Hello, I have created a repro project and logged a bug like you suggested with title "Unity IKHintPosition and Unity IKPosition" I have explained how you can see the bug and also how to see it working with left elbow as ikhintposition and right hand as the ikposition, the case id is #851217.

Please notice that I am using Unity 5.5.0b2,if this was a known bug that was fixed in the next unity update please let me know so I can download it, thank you.
