Maya Animation :: Parent Constraint Not Working Properly For Hand Writing
Feb 26, 2014
I am trying to get the hand to write with a pencil. I pose the hand and fingers holding the pencil and constrain (parent constraint with offset) the pencil to the hand's wrist controller and freeze the pencil's translation attributes. When moving the wrist controller creating key frames or translating in the UI, the pencil does not follow the hand/fingers. There seems to be an offset with the pencil that get worse the farther I translate or rotate the wrist controller. I tried doing the same with just the fingers and getting the same result.
I've a character writing on something (it could be paper, wall, etc). Now I'm looking for a way that attaches brush to his hand for interactive writing on that object.
Don't say I have to sync it manually! it's a close up shot and motion captured movement. Indeed it's really complex movement! Imagine you are painting on a sphere with Maya's texture paint tool.
My problem:There is the parent node (Base) and the child nodes (arm1, arm2, ...). When one of the children (arm1) is picked up all the lower parts in the hierarchy (arm2,arm3) moves, rotates... with their parent (arm1). But if Base is selected and rotated, the child nodes will stay where they are.
I tried to set and unset the "inherit transform" box, but this seem to take no effect.Everything behaved well until i added the point constraint, although i did it as told in the tutorial.

What am I doing wrong or where can i change the Settings that set the hindrance?
For some bizarre reason, no matter what tool I select in the tool bar the only icon that will show up on the canvas is the hand tool, I can't change it and consequently I can't do anything but move the image around.
I have installed all the updates and patches, I have tried everything I can think of to solve it and get back to work but no other tools will work.
The basic premise is that I've built a grid of 100x100 tiles and aim constrained them to a locator. Now I'm wondering if I could somehow attach an "area of effect" to the locator so that only the closest tiles aim at the locator and the rest lay unchanged?
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.
In maya 2012 n 13...the end joint not matching to parent joint...
after creating leg joints are spine joints...we set the orientation of joints..but last joint wil put NONE in option box right....after applying this the end joint orientation still in world axis instead of parent joint..
is this bug are is there any other option(other then jointOrientaion in the joint attributes)..
Parent assemblies of the one being edited in place report being changed when a constraint limit is enabled. To reproduce, open Assembly3 (attached) and edit Assembly1 as shown.
The unit basically consists of 3 short cones which at tilted at 30 degrees to the horizon and each on spins on it's own. In order to get them rotating properly I had to assign a TCB quaternion controller. With these three 'cones' rotating on their own I need to have the entire setup rotate with these guys still rotating individually.
google images "oil drill bit" to get an idea of what I'm putting together.
So I link these animated cones to the parent main shaft. Once I do this I lose all the rotation animations I had given to these cones.
Horse auto rigger not working after much of tweaking. which keys to use like trans +ins or d+v.
When i tweak less then all controls are visible other wise leg, tail,main and ears control are not visible. how to adjust the bones so that all controls are visible. [URL]
I've got a problem with simulating a benchframe. The frame is attached to the car's body with 4 flat braces. I now want to attach the braces to the benchframe, but leave them to be able to rotate from each other.
I have fixed them to the body using a pin constraint, which works pretty straight forward but I'm not able to get this working on the side of the benchframe.
I have placed 4 pins, to allign the components and assigned manual contacts with "sliding/no separation" but now the whole construction doesnt move sideways in the X-direction and enormous stresses are developed because the benchframe is not deforming either. I have assigned every contact point and surfaces between the benchframe and the braces as "sliding/no separation".
I'm trying to find a way to have an object's rotation axis match it's parent's. In Softimage, this can be done with Freeze Rotation Transform (or some similarly named command), and it will reorient the pivot axis to the parent's. Trying to find Maya equivalent.
It's not important that it match it's parents transform. If there is a way to have an object match any other object's rotation axis, yet maintain vertex positions in world space, that's just as good.
I have a chain of spheres linked a linear manner, i.e. sphere10 is linked to sphere09, sphere09 is linked to sphere08,sphere08 is linked to sphere07, ..., such that sphere01 is overall parent.
I am trying to lock the distance between the children and their parent so that when moving them around, they are always the same distance from their parent. Almost like the child is pivoting around the parent's pivot point. However, I can't seem to figure it out.
I can get it to work if I turn Interactive IK on, but I do not want the movement to affect the orientation of the parent.
I have several parts that at a point in time come together and need to rotate together around a common point. However, when I animate them it will only let me rotate them around each individual part's axis. How can I temporarily link these parts to a parent dummy object so that I can rotate them together? I want this to happen midstream in the animation and after the rotation I will be decoupling the parts and having them do different things..
So i started making my own rig and at the end when i was testing my clavicles i realized they dont move the bones so i went back to try and fix them by attaching the bone to the control using orientation constraint but because i already finished the rig, the constraint does nothing. Is there a way around this? I really dont want to start all over again.
I know how to use Link Constraint but I've yet to find anything on linking an object to the biped mid animation. I have a world link and the link constraint applied to the weapon but I can't get the arm to move to continue the animation. It's like the arm is stuck. I know it probably pertains to the World Link but don't know how I should handle this.
is there a way to show and use the transformation and rotation values of an object after using an path constraint e.g., without using another EulerXYZ in the stack? I know, i could use an ExposeTM, but i'd like to avoid this.
How to stop an object from flipping along a Path Constraint. I have a pflow source traveling along a circle path. Half way along the path it flips shooting the particles the other direction.
i'm trying to generate a path constraint for text to create a Pf source to highlight the perimeter of the text. i have fused the text vertices together to generate a continuous path. however, when constraining the Pf source to the path it only follows one letter. any assistance would be grateful
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 my background on the screen; click text tool, specify font, size, color - then i click on my background expecting the text-writing box to appear, but instead a mini-copy of the text tool options box appears, of no use or function. How can i get the text-writing box to work?
PS An empty box appears on the background, supposedly to write in, but it doesn't work. I type and nothing happens. And, there is a huge cursor bar (?) that extends down the screen.
When I record an animation in .avi using the Drive Constraint command here's what pops :
-The codec you selected to compress this AVI video stream cannot handle the current screen color depth and/or the graphics frame size. Please try another codec.
-Then I press OK and it records but the AVI file is empty and no video is watchable.
What can I do?
I'm using Autodesk Inventor 2012 ans a windows 7 64bit brand new computer with Nvidia graphic card.
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.
