Maya Animation :: HumanIK Zero Out Controls
Feb 10, 2012
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 suffer a problem that my arm (rigged with humanIK , Maya 2013) can only bend a little angle but can`t bend anymore.

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.

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 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.

how I could go about adding visibility controls to select parts of a single skinned mesh?
I was watching Jeremy Ernst's rigging showreel [URL] and the mesh visibility controls are shown at 4:06..

I'm looking to import a rig into a maya scene but every time I do the skeleton joints appear and it's hard to click on the controls. I have opened up the rig file and it's completely fine with no skeleton showing. Why is this happening?

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?

I just got Maya 2012 student edition. I created a quick rig with the default maya settings (Skeleton gen, Characterization tool, Character controls).
The position of the rig doesn't update until I let go of the controls. On other rigs the rig updates real time.

why my facial control rig is not updating my character morph targets in real time? I would have to go into the modifier in order to see changes after clicking the slider. I used both the reaction manager method and the wired parameters but neither is working.

I have rigged a character and made it into a character set in which i have locked the scaling attribute , I have then saved this file. I have then referenced this file and and have done a walk cycle animation and saved this file. I have then realised that I needed the scaling attribute when I have added other parts of my scene. Is there a way to unlock the scaling attribute in my walk cycle animation file or will i have to go back and change it in the rigged file, create a new character set and do the walk cycle animation again?

My current scene has 10 animation layers for a character, and seeing every f-curve from all layers, although grey and locked, when I only need to see the f-curves in layer I'm working on is really cluttering the graph editor. My current work around is selecting my active layer in the Layer Editor every time I select a rig control. Simple enough, but a pretty inefficient way of working. I can't seem to find a setting that allows me to just see ONLY the fcurves in the active layer. I imagine some of you out there may have hundreds of animations for a single game character.

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 an assignment for a class where part of the final project is detailing the construction of a mold for a part. The animation that I would like to do would show the build up of the part in a 3D printer layer by layer. The closest method of animating this that I can think of is unfortunately backwards.
As I would have the part and a camera facing up from the bottom of the part and would have a plane that would recede upwards in the y direction. This would reveal the part as the plane translates in the y direction.
This might be okay, but the problem is that I would like to show this from a camera on top facing down instead of a camera on bottom facing up. How I can create the look of a part being built up in this additive method?

I am trying to add an expression to the standard Mudbox car to make the wheels turn when the vehicle moves in both the X & Z dimension. I have found many scripts that let me do this in a single dimension. I have found some others that claim to work for both dimensions, but at certain angles the wheels turn in the wrong direction.
My work flow is as follows:
1 - Export car from Mudbox to Maya
2 - Separate the wheels & center pivot all items
3 - Add NurbsCurves to create a rig
4 - Parenting the elements of the car
5 - Add an expression based on this web post [URL].......
6 - Test the animation
It works great when translating the car in the Z axis, but when the car is rotated 95 degrees in the Y axis the wheel will only go backwards no matter which direction the car is moved.
I have attached an MB (Maya 2013) so you can see the
problem.mudboxcar_maya_2plusexpression.mb.zip

translate facial motion capturing data (basically 2d point clouds) to blendshape weights. I finished rigging my character and wanted to drive my blendshapes by the relative position of my tracking data, e.g. distance between corners of the mouth drive the "wide" blendshape and so on...
Hope YOU know a solution for this, I believe blendshapes are THE way to create realism in tracked animation but I was not able to find ANY reference to something like that. I'd like it to be customizable and not to expensive, so the imagemetrics faceware service won't do for me

I have a character with animation. Another character is the same(same bones, meshes), but with no animation, 100 times larger in size and I resize the head to make the head looks slimmer. They are saved in different fbx files and I imported them into mb scenes. I select the root bone and "select hierarchy", the export options is shown below. Then select in the same way in the larger character's scene, the importer options is shown below. THE PROBLEM is: after I import the atom, the character becomes shrinked to the same size as the former one and the ratio of head becomes the same as the former one too.

For some scenes we have a chain which is wrapped around several cogs, just like a bicycle. In this scenario we need the chain links to follow the path and retain their relationship to each other.
In other scenes we have a chain which follows along a changing path. Imagine this if you can: A heavy weight has a chain attached which goes vertically up, over a pulley and down the other side where it is attached to a lorry. The lorry drives off pulling the weight upwards. This is my challenge!
Should I individually constrain the links using a Pin constraint and use dynamics completely to keep the chain taught?

Was wondering if there is a way of getting random camera movements? For example, i am doing a fly through of an earthquake scene and as the camera animates along the street it randomly shakes with the earthquake shocks.
I know I could animate it by hand but I wondered if there was a way (perhaps an expression) to make it more simple?

I have made a 3d Spectrum analyser , its made of rectangular boxes 16 rows and 16 boxes in each row.
So i have made my cam from Bottom Left corner to Top Right over 96 Frames.
What i need to do, is make some of the blocks disappear and re appear as the cam pans across.
In sketchup i did it by HIDEING the component (block), make new scene, then un hide it..

I want to key frame animate something to go in a straight line but it seems to start out slowly, speed up, and then slow down again at the end. Is there a way to make it so the object moves the same speed throughout?

I have an animation layer that I have exported and Im trying to import it into a new file and then merge it down to the base layer.
what ends up happening is that when I do the merge i get two additional layers. and the layer with the animation stays there. and nothing gets baked. the animation stays in the imported layer.
I should be able to import/export animation layers right?

I have a image plane. I would like to move the image of the plane in animation. It looks out then masking. I need only some parts of the image in frame one, and I need other parts of the image on frame 100. The plane isn't moving, only the image is moving in the box.

I've been working on an animation for a week or two and all of the sudden the file no longer plays the animation. The keyframes are there and I can scrub through them, but when I hit play it just hangs on the frame it's already on, it says it's playing (The icon changes to stop and in the corner it says "Hit ESC to stop playing", but nothing moves. I can bring it into older versions of Maya and it plays, but the only other version of Maya I have is 2008 and it doesn't like the transfer from 2011 to 2008.

i'm actually starting to design and code the animation part of the pipeline for my studio. So if you have a given shot in a given version, you have a bunch of animations for all characters/props, and you can publish a version of your animation and rollback your animation to older versions.I have two kinds animations exported : one "normal" and a geocache version also. For the geocache, I use Alembic and for the moment I'm pretty happy with the results.
For the "normal" version, i was thinking of using animImportExport module from maya. It seems to work fine, but then comes THE issue I remember having to discuss for hours in all the studios I've worked : what about the constraints?i have my character, for example Ogre_chr (group node) and i export all anim below that node and call it Ogre_chr_Shot101_v01.anim. But if there's a constraint outside the ogre, it won't be exported. I could take the anim of the object that is constraining and add it to my .anim, but imagine two characters interact with one same constraint : saving versions of both characters will cause issues when you play around with loading different versions of both characters.
