Maya Animation :: How To Link The Blend Shape States For 2 Objects
Jan 6, 2013
I'm rigging a character for use in Maya 2011, which I'm not all too familiar with - How would I link the blend shape states for 2 objects, so when I increase the value of one blend shape for one object, it increases the value for another blend shape for another object?
I have a blend shape for the mouth open position & I need the teeth & tongue open blends to match as the value increases.
In 3DS Max I'd use the reaction manager - is there something similar for Maya?

I went through all this hard work of making a blend shape. and I forgot to name it properly.
can I rename it in the input channel?
I know I can just set it to 1, dupe, and add it again. but it would be nice to just quickly give it a name....

So I was in the midst of making blend-shapes for an animated wizards staff, but one leaf wouldn't deform like the rest.
I know I selected the vertices properly when altering it, but every time I try to create a blend shape deformer I get the error "Error:// no deformable object selected.
Why it would be non-deformable?

I have a scene with an object with multiple blend shape targets. I'm not using custom attributes to control these targets (since doing that makes the Blend Shape Editor nonfunctional). I'm just directly changing the value in the channel box's 'Input' section, under 'blendShape1'. By typing in the number directly, I can get it to work with any number I want, but if I try the Maya Cntrl-drag method to interactively change the number, I'm stuck between values of 0 and 1. Is there any way to change the min and max of these attributes? Its strange that I can type in whatever I want and it will work, but cntrl-dragging does not work that way.

so i know if you want two blend shapes to happen at the same time they have to be in the same node.but what if i want 2 separate nodes? say: one for body shape, one for face shape a blink, and an inflated belly, that i want to happen at the same time? I don't want it to be all in one node, but 1 cancels out the other depending on the order.

I have a rigged object and I would like to add a blend shape to this rig. Now my blend shape is not for morph animation rather it is for manipulating the original geometry. Put it this way, I modified the original object and I would like to put this new shape in place without changing my rig, or transferring weights or bones. I presume that best would be to put this before the rig deformer so that the bone deformer works on top of it? I am not sure how I should handle or approach this.

I have a rigged human character with many corrective blend shapes, which sometimes overwrite each other. For example, the corrective blend shape on the finger, when activated, "un-does" the corrective blend shape on the elbow, when both the finger and the elbow are bent.
I have tried the input editor, and can change which blend shapes overwrite what other blend shapes, but they still overwrite each other.
My next step is to try and paint the areas which the blend shape affects (stop the finger blend shape from being applied to the elbow). However, when accessing the "Paint Blend Shape Weights" tool, most of the target blends do not appear in the list. Two target blends do appear, but the two which appear are seemingly random and have nothing that sets them apart from the other blend shapes which do not appear.
When creating new blend shapes from the same base mesh, the new blend shapes also do not not appear in the target blend list.
When attempting to duplicate the problem (with several cubes), the issue is not present.
How to prevent the blend shapes from overwriting each other, or how to fix the issue with the targets not appearing in the paint blend shape weights list? Attached is a screen grab of some of my blend shapes visible in the blend shape editor on the right, and them not being present in the paint blend shapes weights list on the left.

How can I change the range at which blend shapes are created? In other words, blend shapes are created with ranges from 0.0 to 1.0. How could I change it to, for example, -0.4 to 4 without using a custom attribute?
I'm aware I can type -0.4 or 4 in a blend shape target. However, that will mutiply the effect which is not desirable.

I have run into an issue relating to the differences in the way Mudbox and Maya subdivide meshes. My workflow for creating blend shapes is as follows:
1. Create base head mesh in Maya
2. Import base head mesh into Mudbox and subdivide to level 2
3. Create a Mudbox layer on top of base head mesh to sculpt each blend shape (e.g., browsMidUp)
4. For each blend shape, export the level 0 mesh to Maya for use as a blend shape on the base head mesh
Here is where it all falls apart.
When I smooth the blend shape in Maya (either by choosing smooth preview or by selecting Mesh>Smooth), the smoothed mesh in Maya differs from that in Mudbox. In the case of browsMidUp, the blend shape created in Mudbox only modified the brows. However, in Maya when the blend shape is smoothed the mouth opens up (i.e., the lips smooth differently in Maya than Mudbox, causing the mouth to open).
This is incredibly frustrating because I did not discover this problem until after I created approximately 35 blend shapes in Mudbox!I believe I can work around my current error. However, I would like to know how others approach the creation of blend shapes.Do you use Mudbox? If so, how do prevent issues associated with smoothing differences?

I've recently upgraded from Maya 7 (32-bit Windows XP) to Maya 2010 (64-bit Windows XP). In Maya 7, I used corrective blend shapes to fine tune skin deformations by the bones of a character's skeleton. I used Parallel blending, and it all worked very nicely.
I've been trying to do exactly the same thing in Maya 2010, and it works fine with the character in its default 'T' position. If I then try to pose the character, the corrections become progressively worse the more extreme the pose.
I'm using the same technique as I did in Maya 7, so I'm wondering if something has broken.

Like in title, when I apply blendshapes to mesh with skincluster, I cannot paint weights anymore. It sais:
"maya expected a skin cluster deformer or a deformed shape. Found *.*blends instead".
I tried both, applying skin cluster first and blends first. I know for input graph (there are no issue).
There was no such problem with Maya 2011. I use Setup machine for the rig.

I want to rig a face for animating. (not for a game). and I can't figure out which is better and why: having all joints, and those joints driving parts of the face.. or just making blend shapes for all expressions like smile, angry, sad etc....
I know blend shapes won't work for games, but I'm planning to do mmo's anyways so I'll never need a complicated joint setup for faces... but as far as film, what works better?

how to link a biped's head to an object? I can link it to other objects as the parent, but I need the head to be the Child.
I'm trying to animate a Terminator robot model I found here (it was a free download):
[[URL]
The model is rigged to a biped, and I'm trying to animate its head to follow the exact movements of a person's head in some footage I shot. I used PFTrack to motion-track the person's head (using geometry tracking) and exported the track as a MaxScript. So I run the script in Max and it produces a camera and head model which exactly follows the movements of the original person.
how can I link the Terminator's head (or rather, the biped controlling the Terminator's head) to the animated model? Better yet, how do you link a biped's head to Any object? I can link any object TO the head, but I cannot make the biped's head the Child. How to do this? I also tried using Select IK Object in the Motion panel, which works for other parts of the biped, but not the head.

I am modeling a (simplified) human brain. I have used paint effects to draw its surface and afterwards I converted them to polygons ( Actually I used this tutorial URL.... ). Is there a possible way to convert these tube - like polygons to rectungular shapes? I want in a future step to make an animation where the brains topology transforms to walls and corridors.

I made a Robotic arm whose function was to pick a dropper from a beaker and pour the droplets in another beaker from the dropper and then place the dropper back into the first beaker.
I used combine to attach the dropper with the robotic arm; everything worked well but when i placed the dropper back into the first beaker and rotated the arm back to its original position all the groupped objects got scattered ...

how to keyframe a light / object to be visible and invisible in my animation.
I just need it to disappear in the scene after a certain time. I know of the "Visibility" check box, but it can't be keyed.

I used to be able to create quick a makeshift skeleton for things like robots by parenting the objects that make up the robot to each other hierarchically. But the past few times I've tried to do the same thing, the child objects deform in weird ways when I rotate the parent. I looked and found a few references to this in forums, but not a single solution. The idea of going through and setting up either a proper skeleton, or parenting everything to group objects seems unnecessarily complex and frustrating when there was a simple solution before.

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.

I´d like to know how to move/displace multiple objects (in this case bricks) like it is done in this animation (at approx. 0:15 sec) [URL].I tried to reconstruct the effect using bigger bricks and tangent constraints, which worked kinda ok but I had to constrain every single brick manually which was rather time consuming and definitely not the approach they must have had used. Is there a way to achieve similar effect (pref. without scripting)?

I have a character who is wearing a vest with buckles on the side. Binding with skin weights creates distortion of these buckles, so it's not a good solution. So I'm experimenting with Duncan's Parent To Surface script: . It seemed to work ok until I noticed that when my character bent forward or backward the buckle di...

When using the blend tool to blend colour between two objects is there a way to see the anchor points so I know where to click the blend tool. I realise the cursor changes when over one but its seems very cumbersome to have to move it around until it changes rather than click directly on one which I could do if I could see it.

I had downloaded Photoshop CS6 from the official Adobe site here URL....product=photoshop), and wanted to only test it out. uninstalled all my Microsoft Visual C++ products, not knowing that these were important for Photoshop. Anyways, Photoshop was having all errors etc. and I had to uninstall it (the 30 days weren't over yet, by the way). Now I have downloaded the Microsoft C++ products again, and I wanted to download Photoshop CS6 Extended again - it all was installed it perfectly, but when I opened the program, it was just Photoshop CS6 and not Photoshop CS6 Extended (and I want it because of the 3D options etc.) - and I was using the same download link from above. So, why has it downloaded the "wrong" product now?

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 have been having issues with using the blend tool on my object. If you look at the picture, I had one outer shape that was what I wanted shaded and a thinner shape that runs inside the other. It blends perfectly fine everywhere except at the bottom. I don't know how to explain it or what went wrong but I can't figure out how to make the blend fit inside the shape.

I've used the blend tool to make a series of lines between two other lines; I need to expand everything so that the whole thing becomes a fill-only object (no strokes):
- I expand it (Object > Expand; Object box checked, Fill box checked, Stroke box checked) and the object becomes strokes-only (no fill at all)
- I expand it again (Object > Expand; Object box greyed out, Fill box checked, Stroke box checked) and the object becomes fill-only (yay!) except the shape of the lines has changed (boo!). Unchecking the stroke box and leaving only the Fill box checked seems to have no effect, the object remains stroke-only).
