Hi @Partel-Lang ,
I am currently working on Leap Motion using the VRIK, in one of my scenes the player stands on a hoverboard and is flown through the scene. The problem I’m facing is the player model being left behind due to the IK performing the stepping motions. Is there anyway to disable the locomotion/walking?
Hey,
How can you make a local multiplayer VR game? I mean I thought a computer can handle only one VR device at a time.
Hey,
Don’t worry about it. You can rotate the bones in the Editor, animation will overwrite those rotations when you hit play.
Hey,
PuppetMaster is independent of whatever the IK does, it’ll just follow the pose physically, so it might be a good idea to use that for the hit reaction and ragdoll part. You’ll just have to see if the added cost in performance is affordable in your game.
Best,
Pärtel
Hey @Partel-Lang thanks so much for the fast response. One final question - when I have an object in my hand, what is the best way to twist it (for example if you hold a bottle but you then twist your wrist to read the label on the back of the bottle). It seems like I need a rotation offset, much like the position offset you describe in your tutorial videos but there’s doesn’t seem to be an equivalent. To give you context - once an item has been picked up, I want to rotate it around it’s axis by moving mouse left/right.
Thanks so much again
Hi @Partel-Lang .
First of all thanks so much for your efforts. I watched the tutorials you made about the interactions. I have a question in mind. All of the actions in tutorials are with idle animations. What about a run animation. Like dribbling in a soccer game. I am thinking I can use Final IK to reach the ball and apply a force to it while running. But the position of the leg may be a problem. The leg will be different positions while running animation. So, the distance to the ball will be various. The IK movements will not be the same for all the time. What do you think of it? Have a solution to it. Thanks.
Hi Partel,
I would like to use final ik to do some ducking animation on top of a running animation and tried using the head effector but the hands seem to go crazy if I let the head go low, they start intersecting with the body and in some case I think it has a gimbal lock issue. Strangely it happen only on one arm, the other animate fine.
I found a message saying the head effector is not being worked on anymore and now you should use VR IK.
I tried VR IK(although I am not doing VR) and doesn’t seem to have the issues.
What’s the drawback in using VR IK against Fullbody biped IK?
Is it a lot more heavy on the cpu? Any missing features?
Hello there @Partel-Lang !
I had a question about using FIK along with Slate - Cinematic Sequencer. I am using a script you provided on my character which you called EditorIK that allows the solvers to work in edit mode which allows me to scrub through my sequence and what not which is great, though I seem to be having an issue with it.
I first tried to have the script disabled and then enable it when I needed the characters arms to move to a certain point but having the EditorIK Script enabled seems to always fully overwrite any animation that may be playing. I tried adjusting the order of operations of things but that doesn’t seem to help any. I tried to mess with the weights as well. As soon as the EditorIK script first on it will kick my character to T-Pose if there are low / no weights, or it will go straight to locked position, of course, if it’s at 1 but it just kills the animation. I tried it with both FBBIK as well as the Limb IK, they both seemed to do the same thing from what I could tell.
Do you have any suggestions in which I could try?
Thanks!

Hey, you could just apply rotation offset to the hand bone in LateUpdate.
hand.localRotation = Quaternion.Euler(handRotationOffset) * hand.localRotation;
Hey,
Please check out the “Soccer Kick” demo. It uses a technique I call Animation Warping to move the foot to the ball. That can also give you a bit of freedom with a running with a ball animation. You can set the weight curve of the animation warp to go up to 1 every time the foot is supposed to touch the ball in the animation and back to 0 when it doesn’t. I’m not really sure how it would look though, haven’t tried this myself.
Hey,
With VRIK you can’t pull the body from the hand, the spine won’t follow as the spine is supposed to be controlled by the HMD. There are no other drawbacks, it is actually twice/trice as fast as FBBIK.
If you need to do ducking animation with FBBIK, you don’t actually need to use the head effector. You can pull the head down by the shoulder and body effectors. You can try that in the “Effector Offset” demo if you play around with the shoulder/body effector offsets in there, try to move them down a bit.
Hey,
If you open the EditorIK script (just a few lines of code), you’ll see in the Update function the line about fixTransforms. That must be the thing forcing the character to default pose so you can try disabling “Fix Transforms” in the IK component. Not sure how Slate works, but animation should be updated between fixTransforms and IK update. That fix transforms thing is just for making sure there is no IK applied additively on top of itself, should there be nothing (normally the animation) overwriting bone rotations in between.
Best,
Pärtel
Hi, I have a small question about getting the FBBIK Grounder to work together with Aim IK and two handed weapons.
I am using this script from this video (
) to get my left arm aligned to the weapon. On top of that I am using FBBIK Grounder. The problem as I see it is that grounder is applied after and thus moving the character to fit the ground but not the weapon and the Aim IK stuff. ( If the character stands on a edge the grounder moves the character down so the feet touches the ground but the weapons remains higher up and do not move with it.) Not sure if there is any easy solution to fix this.
Edit: I am also trying to get the Recoil script to work good with the same script. So any help there would also be appreciated.
While on the subject I also wonder if there is any best practice to use FBBIK with effector offsets together with Aim IK. Basically I want to use AimIK and at the same time use effector offset to change the position of the weapons during gameplay.
Hi
I have a problem with a simple interaction
why happen this to the legs. (the interaction is with the left hand)
thanks
Hey,
If you wish to do recoil, I suggest you start not with that tutorial, but with either the “Firt Person Shooter (Recoil)” or “Third Person Shooter (Recoil)” demos, whichever you need. Those already work with AimIK, the Grounder (just add GrounderFBBIK) and effector offsets (just add EffectorOffset).
Hey,
If you select the FBBIK gameobject while in Editor mode, do you see little blue arrows on the knees in the Scene view? They indicate the bending direction of the knees.
If there are yellow/red dots instead or if the arrows are not pointing forward, rotate the knee bones so the that the limbs are bent slightly in the direction you want them to be bent by the solver, like in this tutorial.
Best,
Pärtel
Thanks a lot, I’ll experiment with both.
EDIT
I found how to fix the arm swaying with the head effector, had to use “maintain relative pos” in the hands effectors, didn’t know this had effect even when their weight was zero.
Without that even using shoulder effectors to duck the arms go everywhere.
Hi. I have a couple questions.
2)Will there ever be a an organized forum for FinalIK? You are great at answering questions but navigating this forum when looking for something can be a nightmare.
Thanks.
Hello Partel,
I have two question befor we buy. Our Indi studio want to work with your VRIK but we dont know if you can lay down on the ground. We saw footage that you only can knee down and thats not what we look for, in our militär Sim. Best way, for us, is to push a button to go to the ground level with the cam and lay down with your real body. Is that possible with vrik at the moment and a solution, when its possible, would be really great?
Next question the movment of the legs, we saw in VRIK, is not natural. I mean both foot walk parallel and not in front of each other?
Mfg

Hey, sorry for the delay…
Is the picking up done with InteractionSystem? Could you please send me that character fbx and the animation that plays (looks like idle?) when you pick up that object, to support@root-motion.com, I’d like to take a closer look at that.
Hey,
With VRIK, you can add Vive trackers on the feet and body, so 3. You can also add trackers on the knees and elbows, they can be used as “Bend Goals”, which means they don’t move the knees/elbows there, but they can be used as hints for the arm/leg bending direction.
Yes, as soon as I’m done publishing the next versions of FIK and PM, improving support channels, including forum and Q/A is next on my list.
Hey,
Yes, if you play a prone animation, and adjust a couple of parameters in VRIK (“Min Head Height” to 0 and “Maintain Pelvis Position” to 1 in the spine settings), you can make it work.
About the movement of the legs, what you saw was probably the built in procedural locomotion of VRIK, that was designed for a bit of leg shuffling in a couple of square meters space, not good for room-scale or thumbstick locomotion. You can disable it though and use a standard strafing animation blend tree to make the character follow the horizontal direction towards the HMD with root motion and/or script while VRIK keeps the head and hands locked to their targets.
Best,
Pärtel
Hi Partel,
I have question for VRIK.I want to use VRIK feature to arms and head and mix animation for it.I set locomotion weight for zero and looks is fine.But i rotation “Head Target” Yaw, the feet also rotate. What should i do? I want arm and head following controller and leg following animations.Looks like upper body and lower body separation opertaion.
Hope to get your reply.
Thanks.
Hey,
Set “Max Root Angle” to 180 in the Spine settings so the root won’t be turned towards camera forward.
Partel-Lang, good day!
First of all I want to say thanks for the excellent asset! Best tools i’ve ever had.
Could you please help me with the addition of the 1st person view? I can’t understand the code completely and that’s why I can’t improve movement for 1st person.
What exactly isn’t clear:
move = camera.rotation * new Vector3(h, 0f, v).normalized;
**Camera (2nd cam for 1st person view) is always on the head
2) How to improve that code:
switch (moveMode)
{
case MoveMode.ThirdPerson:
if (isMoving) return movementController.state.move;
return lookInCameraDirection ? movementController.state.lookPos - r.position : transform.forward;
case MoveMode.Strafe:
if (isMoving) return movementController.state.lookPos - r.position;
return lookInCameraDirection ? movementController.state.lookPos - r.position : transform.forward;
I hope you can help, since I already weakened from trying to do it myself!
SOLVED, IF SOMEONE HELPS, I WILL GLAD:
In the method Rotate():
r.MoveRotation(Quaternion.AngleAxis(angle * Time.deltaTime * turnSpeed, transform.up) * r.rotation);
Changed for:
if (moveMode == MoveMode.ThirdPerson)
{
r.MoveRotation(Quaternion.AngleAxis(angle * Time.deltaTime * turnSpeed, transform.up) * r.rotation);
}
else if (moveMode == MoveMode.FirstPerson)
{
r.MoveRotation(Quaternion.AngleAxis(movementController.inputHandler.MouseX * Time.deltaTime * turnSpeed, transform.up) * r.rotation);
}
movementController.inputHandler.MouseX - float value of Mouse X Axis from Input Manager * Sensivity
Hi,
We have a problem about VRIK to build as exe file,
in Unity editor play mode the VRIK panda model just run good (shoulder and arm are not twisted or stretched),
But when we build project to exe file, the panda model does not look normal,
(shoulder and upper arm were twisted and stretched, and when my arm lift up, this situation is more obvious)
Is there anyway to solve this problem?
Best,
Antoine Lee.
