Maya Animation :: Automatic Rotating Wheels Only Work On 1 Axel

Jan 9, 2013

I am making a cart that whenever you move it, it should rotate the wheels automatic. I did this using expressions. At this moment I have a code what makes the wheels spin when the cart is moved on the Z-Axel but now I want to have it work on the X-Axel as well so the cart can make turns.

This is the code I'm using on the wheels: frontwheels.rotateX = cart.translateZ*40;

Maya Animation :: Expression To Automate Animation Of Wheels

Oct 10, 2012

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

Maya Animation :: Why Joint Orientation / Rotational Axis After Rotating Bone / Freezing Transformation

Nov 21, 2013

I want to know after rigging why should i orient joint in the attribute editor using the channel "joint orientation". Because i can easily fix the rotational axis after rotating the bone and freezing transformation.

3ds Max Animation :: Rotate A Set Of Wheels Like Locomotive Train Wheel

Aug 20, 2011

I am trying to rotate a set of wheels that are moving like a locomotive train wheel and having problems. I was able to animate the wheels to move like a locomotive wheel by linking and turning off the z axis inherit for the red rod (see attached images. Image ex04.jpg.)

The problem came when it was time to rotate the whole thing. I grouped everything and rotated the wheels around as a group. As the red rod had is z axis inherit turned off once it started to detach from it location(ex06.jpg), which was kind of expected.

I am not sure what to do to solve this problem. Do i create a bone structure with IK handles to resolve this problem or is there something else better to solve this problem?

Maya Animation :: Unlock The Scaling Attribute In Walk Cycle Animation File?

Feb 17, 2011

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?

Maya Animation :: Hide Non-active Animation Layer F-curves In Graph

Apr 18, 2013

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.

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.

Maya Animation :: Additive Layer Animation For Rapid Prototyping

Dec 11, 2010

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?

3ds Max Animation :: Rotating The Video That Plays?

Aug 5, 2011

I have a video that I need to set in the background of my animation but it needs to be turned 90 degrees. Right now its is side ways. Is there a way to do that within max 20111? I currently have in my environment map and Effect menu common parameter tab my movie. I then have an instance of it in my materials area. Within materials area I can change my W: Angle to rotate that diffuse map where my video is listed and it rotates with materials menue but just not in my animation background. Can I rotate the video that is in the background of my animation?

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

Maya Animation :: ATOM Animation Transfer Between Different Characters

Oct 23, 2012

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.

Maya Animation :: Bicycle Type Chain Animation?

Dec 22, 2010

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?

Maya Animation :: How To Get Random Motion In Camera Animation

Nov 29, 2010

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?

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..

Photoshop :: Rotating Animation With A Seamless Loop

Dec 14, 2012

I'm trying to do something very simple in PS CS6 that's proving to be, well, not so simple (for me at least). All I want to do is animate a layer in a clockwise direction and end up with a seamless looping animated gif. I discovered rotation can't even be animated unless you convert the layer to a smart object, first of all (and by accident. And the "Motion" function doesn't seem to work much at all, where there is a "Rotate" option.).

And of course simply copy-pasting the first key frame in the timeline to the end of the timeline just makes the layer rotate clockwise, then counter clockwise back to it's original position.

3ds Max Animation :: Making Eyelids Conform To Rotating Eyeball?

Apr 3, 2011

There's a great bog eyeball, which, as most eyeballs, is not perfectly spherical, and has a bug bump where the cornea juts out over the iris area. The eye is open, with eyelids above and below the iris, the upper covering the top of the iris somewhat. As the eyeball rotates, it should deform the eyelid, esp. the upper eyelid. What's the next way to make eyelids conform to the eyeball as it rotates, we can use cloth if necessary, but if there's an easier way, with constraints, lattices, etc. Like if there's a lattice on the eyelid whose control points get pushed away by the front of the eye, then fall back as it rotates away, or something..

Maya Animation :: Merge Animation Layers

Aug 16, 2010

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?

Maya Animation :: Animation Doesn't Play

Mar 23, 2011

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.

Maya Animation :: Animation Version For Pipeline?

Nov 30, 2011

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.
