Leap Motion on Full Body with Final IK

[ArnoBen]

Hello everyone,

As few others here, I am trying to use the Leap Motion on a full rigged body without success so far. I have been trying various solutions for 3 days.

Yes, I set the arm targets to the Leap Motions hands. I am having a very hard time to attach the elbows of my model, I just want the same thing as the capsule hands : hand + forearm, but I can't find anything useful for that. I have tried to manually (by script) make my avatar's elbow position follow the position of the capsule hand's elbow but I simply end up with deformed meshes (capsule hand position is real position) :

Now, when I add Final IK, I managed to correct the offset of the hands rotation but it's not great, some rotations are in conflict :

and there is still the elbow position that is incorrect. Plus, whenever I turn my hand, the wrists are twisted because the forearm doesn't follow :

I have searched a LOT for solutions on forums but most of the time the posts are 1 or 2 years old.
I would really appreciate some help.

Best,
Arno

I have the solution of the third problem. There is a script called twristrelaxer in the FinalIK asset. Add this script on the forearm bone joint of your avatar and the wired twist will be solved.

TwistRelaxer of FinalIK F&Q

In terms of the first two problems, they are what I'm facing right now.

TwistRelaxer fixed it indeed ! It's already a great improvement, thanks !
I sent an email to the Final IK dev and he told me he stopped supporting the Leap Motions because they kept changing their API very often and he couldn't keep track, which is understandable.

Rather than opening a new thread I would like to continue a discussion about Final IK VRIK with Leap Motion here if that's alright.

I lined up the hand by making a null object named Target Hand under the Leap hands wrist or palm. I could then rotate that target hand as an offset to 0,180,-90 and the hand lined up well with very little twist. However it has a position offset from the model and when I move that it ends up rotating away from the model.

I know the developer of Final IK isn't supporting leap but maybe the leap users can help figure out how this might be fixed.
I'm on Gemini with an IR 170 but even if others are using an older system the suggestions for fixes are appreciated.

I forgot I had posted this as I fixed the issue after working on a few other things. VRIK target Hand belongs directly under the UltraLeap Wrist. With it there I zeroed the position an set the rotation to match my character avatar. Works fine.
