Maya Animation :: Setting Up A Rope For Animation Based On Control Panel
Jan 20, 2011
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 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.

Need to control playback of the animation based on an anchor in the web page. When the anchor comes into the browser viewport, it would trigger play, pause or stop.
And ... to control the flow/direction of the animation playback based on scroll direction.
The setup:
I would like to have the playback direction for Edge animations placed in a web page, to follow the web Surfer's scrolling direction.
Scrolling down or right, Animation plays forward.
Scrolling up or left, Animation direction plays backwards,
But, that's not all ... I would like to combine the scroll direction sync with ... Anchors
Image if you will:
Multiple Edge animations are placed at various positions on a web page.
Autoplay for each is turned off.
Wish to individually control the playback functions for each animation. - Start - Stop - Pause.
Wish to trigger their playback relative to when an associated anchor (becomes visible / invisible) is inside or outside, of the browser view port.
Sounding complicated?
I put up a web page diagram to illustrate the functions. [URL]....

I am doing some animations involving sine waves, and I can make an expression that controls the translation of an object such that it travels along the path of a sine wave, but I can't figure out how to dynamically create an editable sine wave curve.
Is there a way to have Maya generate a curve based upon the path that an object travels upon?
For instance I have a sphere that is moving along the X axis with time, and also moving up and down on the Z axis back and forth. I would like to make an editable curve object of this path of motion.
I can see in Maya 2012 we will have motion trails where we can see the actual path an object is moving along, and that we will be able to interact with this path to alter the animation, but what if we could take that path and make it an actual curve or NURBS object?

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.

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.
How i do? i need to create a Auxiliary Node in the Character Controls?

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..

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 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 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 am busy working on rigging a character ( See attachment) to the best of my abilities and am running into some issues:
I have made a nurbs curve object which I intend to use as a controller in my rig, I have however modeled my character with his arms in a 45 degree angle so I snapped this particular object to the wrist and aligned it with the geometry...here comes the fun part , because it is a controller I wanted to have a clean channelbox zo I froze transformations which neatly sets every channel to 0, it also snaps the local axis to a world pivot orientation....
I went in componentmode pressed the question mark thingy and thought it was working..but it still alters the values in the channelbox.
I basically want the same rotation axes editing capabilities as I have with joints, I will try fiddling with that next, but I can't believe that this can't be solved any simpler.

There is no motion in my meshes when using set key or auto key.
So lets say I have a cube and set a keyframe at 1 and move it a little to the right and set a keyframe at 13, between 1 and 13 there's no motion from 1 to 13, just it jumping straight to 13. I hope that makes sense, I've tired going to Animate setkey options and checked current manipulator handle, didn't worked.

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.

Trying to animate a rigged model for a class project but I'm running into problems. If I, for example, pick the joint at the top of the hierarchy, in the main view it appears as though everything gets selected. When I try to set a keyframe for the whole model, though, it only gets set on the actual joint I picked, none of the ones below it.
I looked at things via Outliner and see the same problem: I pick a joint there but the ones below it show as unselected in the Outliner window. Right now it appears the only way I can select multiple joints to set a keyframe on them all is to manually expand the tree in Outliner and then explicitly pick each one with command-click or shift-click. If I select an un-expanded joint section in the tree the hidden joints do not get selected, and if I expand the tree and pick a root node the ones below it are not selected.
I have tried this on three different models, including one I rigged myself, and the same behavior is present across all three.
Is this normal behavior for Maya animation? Is there some configuration setting that will change this so I can select an entire skeleton tree via the root node and have all of them accept a keyframe?
I'm running Maya 2011 for the Mac, on OS X Lion, with service pack 1 installed.

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 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

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?
