Maya Animation :: Spine Moving Twice As Fast As Clusters From Spline?
Oct 6, 2012
I am working on a rig right now and I'm trying to do the Isner Spine from the Body Language Advanced 3D Rigging Book.
I did the Spline IK with the spine and I have everything stretching fine but when I made the CVs into clusters and parented them to the controls, when I got to translate the rig, whether I use the Root CTRL, Main CTRL, or whatever, the spine translates twice as fast as everything else. The clusters and everything in the lower body moves normal and everything about the head is moving normal..
I know in other situations with curves you have delete history but I can't delete history on the joints and I can't come up with any solution. I can attach a file.. not all the controls are done right now and I haven't reparented the wings correctly so just ignore that.

I would like to use the same bones to skin a mesh in two different ways. I would like the first weight map to handle how the mesh reacts to the influences' transltes and rotates, and a second map that handles how the mesh reacts to the influences' scale.

Best way to keep clusters in alignment with bone rigging. I'm trying to parent clusters that control facial movements to the head bone of my skeleton so as when I move my character about the clusters retain there position in relationship to the face.

is there a reason that, no matter how I position my arms and spine. the spine joints orientation is always in world space (pointing in x y and z) but my arm through finger joints orient perfectly the way I want them...?
does the orientation of the spine even matter as long as it rotates properly? I can just do a orient Joint command after the spine is made and live with any joint orientation.

Which is the best type of setup for the Spine ? Which one do you use in your rigs ?
I've tried the following setups:
Simple FK
Spline IK
Awesome Spine
Ribbon Spine
Fk Spine(with stretching similar to the IK one)
I am also looking for a scene file which demonstrates "The Divine Spine".

The idea is to have hand drawn characters (our actors) in many different poses,actions and with different expressions,just like in that video.
What I need is the way to easily and fast switch between different drawings.Some kind of a library where I can just click on a picture and it will change to that one.Drawings will be on a simple plane with alpha transparency.
how to add motion blur when drawings are switching

In my scene i have a fully rigged character, with a walk cycle animation on him. what i would like to have is a row of characters walking around. (kind of like how you see military soldiers walk around while in group). The part that is giving me the most trouble with this is getting multiple copies of the same character into my scene.
What i have tried and failed with:
Grouping my full rig and then duplicating.
making instances of my character and messing around with particles.
i have made multiple attempts at trying to use duplicate special.
the only thing that seems to kind of work is making a scene with just one character and importing it into my main scene and changing a bunch of stuff around. with the amount of copies i need this workflow just feels really degrading and tiresome.

I don't seem to be able to increase the number of control vertices in an IK Spline. The number of bones in the chain upon which the Spline is set doesn't seem to affect the number of control vertices I have to work with when creating the spline and I can't find a way to increase the number. I'm trying to animate a fish but finding it difficult to get a smooth wave to travel along it's length with only four control vetices.

I have a skeleton with baked motion capture keys on every frame. I'm wondering if there is a method to convert these baked keys to curves, so it will be possible to start cleaning up the animation. I'm fairly new to dealing with mocap. Perhaps there is a method for achieving this in Motion Builder rather than Maya, that I'm not aware of?

For certain and obvious reasons i need to delete history, problem is since i never deleted it, certain problems occur, like the very binding of my character to the skeleton is undoed, is there a way out of this mess, i just want the texture to stop moving when animation starts.

I'm trying to use the spline IK system to animate a linked 'train' on a path.
There are 4 segments which are joined with a universal coupling. I can only get one segment to actually follow the path, as the others don't follow at all. I've attached my example file.

Or is there no fast forward or fast rewind in the timeline. Like double tapping the "L" key or something in other programs...

I'm trying to scale a spring (which is actually a renderable spline). I want it's scalable boundaries to be controlled by two other animated objects.
I thought a simple FFD modifier with a linked xform modifier to the control points would work, but unfortunately it won't let me link control points.

I've got a 2 bone chain that I have attached a spline IK to with a flex modifier on the spline. This was working pretty well however, once I skinned the mesh to these bones I noticed that when I rotated the 2nd bone it would seem to pop on a different axis. It was hard to spot at first because it popped between 2 frames, popped 90 degrees and seems to happen at the same rotation amount (can't recall exact degree at the moment).
I turned off the flex modifier and it is still popping so I'm assuming it is from the spline IK. Is there a way to prevent this?

I have problem with animating camera along a spline using path constraint. The spline has been spline normalized before added to the path constraint. Then I add besier floating to be able to slow down the camera.
The final camera seems to move not smoothly. This can notice especially when the camera are further away from the origin (0,0).
Some says it's because of Max's coordinates is not fine enough which can clearly proved when import autocad file which located very far from the origin into max and most vertex will be shifted from where it should be in Autocad.

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.

It's possible in maya to sweep a profile along a closed curve? Like in 3DsMax, for example to make a window frame with a particular section profile?

I'm new to the animation aspect of 3Ds Max and I have a running cycle that is stationary but would like to figure out how to get it to move forward? I didn't use Footsteps in the Motion Panel to have a base to work with and modify it. What are my options? I have the weekend off from work to mess with it and if I have to do the hard part of moving the biped forward myself, I'll do so. Would I be able to create Footsteps and attach them to my biped with the animation I have? Or is there a system, option, etc. that I should set up in the beginning before animating that would allow me to move the feet and the rest would follow using the biped?

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?
