Maya Animation :: Blendshape Animation From Motion Capture?
Mar 6, 2012
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

If I create a facial GUI in maya , is there a way to add motion capture to that? What's the best way to do something like this?

I have a list of motion capture, those mocap didn't track the fingers so the hands are always opened. In some of these mocap I need the biped hand to be closed. I've been looking for a solution for about a day now. I think I'm in the good way which is to create a biped layer animation where the hands are closed and link the hands of that layer to the original layer. so I would be able to save that layer and apply it to every mocap animation that need to be readjusted. The only problem is that I'm not sure if it's the better way and I don't know the procedure.

I created a frog character that is all one mesh, and created several facial mouth movement Blendshapes. When I test the Blandshapes they work great. Problem is, when I move one of the bones of the skeleton like his leg for example - and try one of the blendshapes, it blend the mouth perfectly, but also blends the rest of the mesh of the character back to his original position (non-bent leg). I was under the impression Blendshapes were only related to the mesh and not when moving bones?

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?

If I have "dummies" 1 - 3 positions animated, is there a controller I could add to the curved object to rotate and position it in respect to the dummies? I guess the dummies are acting like motion capture points.

I'm testing a puppet rig i've made in 3dsmax of a bird and i've hooked up the bones to the motion capture utility in max 2014.
Would be cool to get FULL support for the dual analogue sticks of the windows Xbox controller as i'm struggling to map the controls to how i want.
here's my first test, recorded live from the viewport.

I made a walk cycle (walking forward). I saved the .bip file and what I want to do now is load the walk cycle and loop it a couple of times so that I can fine-tune a couple of things. The problem is that when I load the .bip file from the "Load Motion Capture File", I get many unwanted keys, as if I were loading a MoCap file or something. I want the same keyframes I used in the original animation, just looped. Been playing with Key reduction settings for a bit, but couldn't figure out how to do what I need.

I have two models that are identical other than the faces. However, when I apply a blendshape, in addition to morphing between the two faces, motion is created in the legs of the target. These are FBX files exported from MB 2011 into Maya 2011.

I've got a Locator attached to a Curve with a Motion Path - the Motion Path is animated so the Locator moves nicely along the Curve. I now want to swap the original Curve with a new one and have the Locator follow it instead.
Is there a way to simply switch curves and tell the Motion Path to use a new Curve while keeping the animated keys in the Motion Path node?
I've tried playing around with the connection editor but cant manage to connect the new Curve to the Motion Path nodes "geometryPath"

I'm currently working on a advertisement for a client and I need to creat a kind of ribbon to wrap around like a present. I thought what would be best would be making the ribbon and then using a motion path add it on but also I would add a gravity field to the ribbon so to moved more like a ribbon.
Also with the motion path I have made them and connected my ribbon and for some reason it doesn't move until the last frame and just snaps to that position?

To create an animation similar to the one shown in the page 225, in the tutorial, I created a curve but I am not too sure that was the correct way to create it.
1. Selected the Surfaces Menu.
2. In the font view, using the CV Curve Tool, created the first half.
3. Using Duplicate in the Edit Menu, I created the other half.
4. In the Edit Curves Menu, selected Attach Curves and connected two curves.
5. I, then selected the Animation Menu and created an object to be used as an aircraft and followed the same steps shown in the tutorial and it worked nicely.

I am trying to attach an object to a motion path but when i do the object goes to the beginning of the path but when i move the time slider nothing happens and when i move the object it isn't attached to the path.

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.

Trying to find the closest thing to 3dsmax trajectory, I'm using a motion trail. Once deleted the specific controller it was used for becomes very very slugish, with over 20 sec to respond.
I tried deleteing all the connections in hypershade and using the delete command but nothing works.

a few things involving cameras. My assignment was to use our plane that we modeled with poly's and animate it on a motion path(used cv curve tool) and have a camera above it follow it. Now I got that down perfect.
But what I don't have a clue on, is how do I attach a camera on the same motion path as the plane and have a camera angle right behind the spinning propeller? Like a cockpit view.

I was wondering if there is a way in maya 2013 to import like 20 takes at the same time, work on those 20 takes in one maya file and export them simultaneously just like motion builder and his "export all takes, save one take per file, use take name".
I'm asking this because i am thinking of switching to maya, but this motion builder native feature is just essential to me.

I have modelling a face in maya 2011. I can see some youtube videos how they put dots in their face, and the 3d-face capture the dots movements. [URL] ....
I want to use dots in my face and a cheap web camera. Does this work in maya 2011? Or do I have to use MotionBuilder? What is the name of the dots?

Once i set up a motion path for my object to follow, it sets the object to follow it over the entire timeline. what if i just want to object to start later on? I want it to raise up, hover over to the path, and then be attached to it.

i have been using the drivenTime node to create walkcycles that follow motion path curves where the out time is connected to some attribute via a unitToTimeCOnversion node.in previous version of Maya.
When i try to connect anything to the Out Time of new drivenTime node the connection never works, not even keyframes?
is there a fix or workaround for this?

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

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?

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?
