Maya Animation :: Constrain HumanIK Control To Object?
Dec 6, 2011
imagine you have a HumanIK character and a vehicle like motorbike or similar, and you want the character to drive the vehicle. Ok then: Parent the reference node (your_character_name:Reference) into your vehicle root. Ok, works fine but now you need to constrain or parent the control of the hands to the handlebar.With maya constrains not work fine and don’t know why.
i need to create a Auxiliary Node in the Character Controls?I’m trying with Parent Constrain, Orient, Aim.. and don’t work properly: Position (tx,ty,tz) work’s fine but X-axis of rotations are inverted… when turn the handlebar to left, rotation turn to right.i trying with offsets or any parameter in the constrain but nothing..

I suffer a problem that my arm (rigged with humanIK , Maya 2013) can only bend a little angle but can`t bend anymore.

i have a model, bound to a skeleton, which is all green-lit in the character controls window. however, when i create a control rig for it, maya creates a new skeleton which the rig controls (working fine) but that is not attached to the original skeleton. what do i need to do to get them linked or to get the auto-rig to manipulate the skeleton that is bound to the geometry already? see attached image as how i can move the bones in the maya created skeleton and its IK, but it doesnt affect the originals (ignore the custom rig panel, that was just me trying another approach to bind the default control rig to a previously made rig that does work)

I am trying to rig a HumanIK character so that both of his hands will stay attached to an object (gun, sword, bat, golf club, etc.). I can get the object parented to one of the hands and it follows along as expected, but cannot for the life of me figure out how to get the other hand to automatically stay attached to the object or follow it.
I've tried parent, point, orientation, etc., constraints using locators, the IK effector itself (wrist) and a few other things. It seems the HumanIK programming keeps a firm hold on the effectors and won't let anything other than the software drive them.
My HumanIK rig is properly setup and its definition locked. Using Maya 2013.

Just started looking at Mayas human IK rig system and initial thoughts are thats it looks quite good. Thats until I created the controls for the rig!
I've previously rigged many characters before (just basic rigs) from scratch and also used some of the free auto rigs thats are around on the net so I know the basic stuff but I'm no expert. But as any rigger will tell you its always best to keep you rig clean and tidy and all controls to be zeroed out at bindpose. This make things easy all round especially when animating.
So going back to creating the controls for the HumanIK when you look in the channel box there are values in some translates and rotates!

I am using HumanIK with Graph Editor to animate my character. First I create pose to pose and then I go to the Graph Editor to set the timing of the animation. In the Graph Editor I drag select multiple keys to get the timing correct. Then I go to the timeSlider and copy/paste keys to make some tweaking. And here we have the problem! When I copy key/keys all are good, but when I am going to paste key/keys Maya give me a fatal error!
Reproducible:
Make a default skeleton from the Character Controls menu and then make a Control Rig. Select HipsEffector set keys on frame 1, 12 and 24. Then in the Character Controls menu go to the Controls tap and left mouse click in the empty space next to the Character image to select all. Now open up the Graph Editor and select all the keys on frame 12 and with the Move Tool shift middle drag the keys to the right.
If you at this point go to the timeSlider and copy key frame 12 and paste it somewhere in the timeSlider Maya gets a fatal error pop up.
If the action shift middle drag with the Move Tool hasn't been used then Maya haven't popped up with the fatal error!

Custom rig to work with the HumanIK system in Maya 2013. Im currently trying to map my custom skeleton and get the mocap data to retarget but the skeleton freaks out when I try to change the source.

I'm trying to animate a moving rope based on simulation data. I know how to import my motion data for individual objects.I've seen lots of tutorials where one uses simulations or soft bodies with IK in order to create a rope. how to use all these features and I want the rope to follow my coordinates exactly. I was hoping I could do something like the following:
1. create points in Maya which correspond to my data points
2. connect the points with a curve
3. loft a circle using the curve as a path in order to make a rope
4. move the points. due to History, the rope position is updated
Is there a way to do something like this in Maya? I've tried, and it looks like ep points do not have key-able channel data, so I can't create animations for them separately. I'm using .mov data file imports to generate x, y, and z motion keys for the points.

I have made a custom rig, mapped it to HIK and got a set of perfectly working controlers. I have used them to animate by hand before without problem but now I have a skeleton from mocap data that I want to use instead.
So I go back to an older save of my project and import the file that I want to get the animation from. Then I make this new skeleton the source and everything looks good. My model is moving just like the mocap skeleton. Great. Since I need to tweak it somewhat and don't want to loose my controls, I then bake the animation to the control rig. This is where things go weird.
If I bake to every frame, all is well. That would make it a living hell to edit later on though so I only want something like every fifth frame. But if I bake only every fifth frame, the animation gets super twitchy in between some of the frames. And I don't see any trace of those movements in the graph editor.

couple of days ago i finished rigging, positionned my character in a nice pose for a render then closed maya. Foward a couple of days, now when i move my rig the character is not following it, he stays in the same pose as he was like if he was frozen.

How to create a Human IK control rig from a pre-made skeleton? I have matched the hierarchy and naming conventions of the pre-made skeleton to the that of the Human IK Skeleton Generator, but I keep getting an error that says, "Invalid skeleton or no skeleton. Can't create new rig."
Can even gotten the Create Rig function to work? If so, how did you set up your skeleton?

I set up my file. I set my controls to where I want them. The Control Curves are in position. I save. Everything is going well.When I reopen the file, control curves have spontaneously moved. Without permission.I've done several experiments with different results, but the same problem: the control curve of my rig are moved from where I had them when I saved the file.

I have a character on a monocycle and what we did was constraining stuff to stuff which I didn't quite understand. Understanding it is not so important for now, it should work in the first place - but doesn't.
We
- pushed the pedals out of the monocycle structure in outliner
- constraintoint the foot to the pedal
- constraintoint the pedal to the wheel axis
- constraintrient the ankle joint to the pedal
- constraintoint the ikHandle to the pedal.
correct the list above if you feel there's a mistake.
Now that we've pushed the pedal out of its place in the monocycle structure, I don't know what to do with it. When i place it where it was before it won't work properly. Perhaps I have to do further steps but this is all I got in class yesterday.

I am working on (yet another) minecraft character rig xD
So i have set up a facial control panel, using blend shapes and driven keys, but i need it to follow my character. If i parent it to the head, i doesn't follow when i grab the skeleton and move the character around, and if i bind it to the neck joint, i am not able to use the control panel, because the movement of the controls are locked, since they're binded to a joint.

1. Windows/Animation Editors/HumanIK/Skeleton Generator - Generate Skeleton
2. Create control rig for it.
3. Set keys to rotate shoulder down and back.
Keys are linear by default and cannot be changed, except to "stepped". Clicking Spline, Auto, etc. Doesn't change anything. Works fine on translation curves. URL....I accidentally check the "force FIK curves to linear" button? It's totally killing our animation pipeline.

i had custom rigs with a character set to store our animations in clips. now i want to do the same with the new humanIK rig. the documentation is not very big on this. it just covers the retarget workflow.which nodes do i have to include in my character sets, so i can store my animations in one file?(retargeted and classic hand animated) or is there any documentation i overlooked on this?

say objectA and objectB are both Parent constraining objectC. how would I remove the constraint of say, objectB? because in the outliner it only shows up as 1 constraint that has 2 W values.

Is it possible to make an object, say a NurbsSphere to always be on top of the geometry in the viewport, like x-ray on joints. That way, I could use a small sphere in say the Elbow as a controller, and it could be inside the mesh but not hidden. Much like what you see here:

Is that really not possible?

When setting up a simple FK control curve on say the wrist for example, many times the control curve isn't exactly perpendicular to the local rotation axis of the joint movement, so when we position the control curve to be perpendicular to the joint - it has a rotational value added, but the rotational handles are lines up with the rotational handles of the joint that we want to move.
Freeze Transformations: then the control curves rotational handle go back to being skewed (out of alignment with the joints)
We want to Freeze transformations before constraining the curve, but we'd really to keep those rotations control handles to remain aligned with the joints rotational handles. This will make it an exact control when animating - grab the rotational handle of the curve, rotate it, and the joint will move exactly in the proper direction.
how to get the rotational handle of any control curve to run perpendicular to the shape after freezing transformations?

In the expression editor, is it possible to get the position of an object at a different time ?
For example, we are at time 100, and I would like to get a given object's position when we were at time 50. Is it possible?

i created a sphere that will control the rotation of the fingers. i align the sphere to the bone so it has the same angles. the bone angle is 0,0,0 but the sphere is (15, 10.23, 2)if i freeze the sphere, the angle get 0,0,0 but they get align with the world axis as X Y Z, how can i 0,0,0 and maintain the align rotation of the bone?
in Softimage there is something call set neutral pose, only change the angle displays to zero so the animator dont have a hard time.

I imported a character model that I downloaded off of the internet into maya, and I have run into a snag as I'm rigging, skin binding, etc. The model has a main body, but its armor is actually separate geometry. My problem is that the shoulder pads and leg armor are mirrored, so that when one moves, the other one does as well, which is a big problem when I want to animate the model. Is there a simple way to split the pieces up so that they are not mirroring each other? My guess is that they were originally created that way so that each side didn't have to be individually worked on.

I have an animated character from which at a certain point i need an object to be 'detached' from the character and animated on its own, problem is as soon as i want to manipulate that part of the character i get this gray manipulator tool that tells me nothing will move, should i give up my whole dream upon this? Maybe i should have visibility turned and switch to a duplicate up to that point in the timeline, problem is i havent been able to move a duplicate either so far, back to hell.

I have this minecraft rig which I downloaded from Shrogg2. I have added a few of my own features but wanted to add things to the facial rig. How the facial rig has been made but I have this plane which has stubble on it. I want it to be fixed in one location but follow the deformation of the jaw when it moves. The controller which is used to move the jaw down is already there, I just need to get it to deform this plane.

When I assign an object to a path using the default setting the object sits nicely on the first point of the cv curve in the path. And moves fine going in one direction but as it goes around a corner it is offset from the curve but continues along with this new offset until the end.

I have an object that I want to rotate different.... not sure how to explain, it, but you can tell what I want by looking at the screenshot attached. I want the rotate to align with the cylinder. I've tried reset transformations, and the home key to move the pivot. I've also tried the different settings for the rotate settings and nothing is changing this angle. Is there a way to manually set this?
