Maya Animation :: Move Files - Specify Rotation And Translation Of Object Using Text File Full Of Numbers?
Jan 7, 2011
My current goal is to specify the rotation and translation of an object using a text file full of numbers. I have been told that I should import a "move" file. However, I can't seem to find any kind of reference about the move file format or how to use it. I see in the import dialog box that there is a file type called "move" but I don't know how to format the data that I put into the "move" file.
Also, I tried to export a "move" file so I could take a look at what Maya generates, but I keep getting the error "// Error: Could not save file "C:/My Documents/maya/projects/body_in_ocean/scenes/examplemove.mov".
I created a group with my object in one file, referenced it in my working file, moved the group around and set some keys in the working file, but I can't seem to export any move data. How to get this to work?

I am animating a ball right now, that is rolling all over the place. Would be cool to animate just the translation of an object and not to worry about rotation. Is there a way? Like.. through the expressions or set driven key? Also would be even better if rotation speed increased as the movement speed did.

How would I find the translation of an object in world space? according to the documentation, translate is not -queryable... once I freeze transformation of a sphere theres no way for me to find its world space, but it still Has a world space because its at a location in the scene.

I have an object that I want to rotate different.... not sure how to explain, it, but you can tell what I want by looking at the screenshot attached. I want the rotate to align with the cylinder. I've tried reset transformations, and the home key to move the pivot. I've also tried the different settings for the rotate settings and nothing is changing this angle. Is there a way to manually set this?

I am busy working on rigging a character ( See attachment) to the best of my abilities and am running into some issues:
I have made a nurbs curve object which I intend to use as a controller in my rig, I have however modeled my character with his arms in a 45 degree angle so I snapped this particular object to the wrist and aligned it with the geometry...here comes the fun part , because it is a controller I wanted to have a clean channelbox zo I froze transformations which neatly sets every channel to 0, it also snaps the local axis to a world pivot orientation....
I went in componentmode pressed the question mark thingy and thought it was working..but it still alters the values in the channelbox.
I basically want the same rotation axes editing capabilities as I have with joints, I will try fiddling with that next, but I can't believe that this can't be solved any simpler.
See the image in the attachment

When setting up a simple FK control curve on say the wrist for example, many times the control curve isn't exactly perpendicular to the local rotation axis of the joint movement, so when we position the control curve to be perpendicular to the joint - it has a rotational value added, but the rotational handles are lines up with the rotational handles of the joint that we want to move.
Freeze Transformations: then the control curves rotational handle go back to being skewed (out of alignment with the joints)
We want to Freeze transformations before constraining the curve, but we'd really to keep those rotations control handles to remain aligned with the joints rotational handles. This will make it an exact control when animating - grab the rotational handle of the curve, rotate it, and the joint will move exactly in the proper direction.
how to get the rotational handle of any control curve to run perpendicular to the shape after freezing transformations?

Pt# 812 (From my drawing)
N: 2004294.63
E: 6057287.18
Pt# 715 (Stake point from a DXF file)
N: 254.39
E: 218.59
I built my drawing from the civils. I wanted to check the points that the surveyors are staking with a DXF file. As you can see from the above two points, our coordinates were wildly different. I brought the DXF file into my drawing as a block, and translated and rotated it to match my drawing. I had to drag it several miles, but no problem there.I imported the as-staked point file to a new group and dragged them up near my drawing, but the drawing was getting a bit crowded by then. So I made a block of all the imported points to make it easier to translate and rotate them to match my drawing and the overlayed DXF. After exploding the block of points, the points showed up in the new group. Anyhow, here's my questions:
1. How do you renumber(offset number) imported points? The option I saw was only for duplicate points. I wanted to offset them all.
2. How do you translate and rotate a large bunch of points without turning them into a block?

how to switch a texture at certain keys, or Keyframe a file texture on a shader at one key and then change the file texture to something else on a later frame, on the same polygon face. Like this...
How to switch or change these two images at different textures at different frames.
Click animation. Here I just keyframed and switched two poly planes. But I want to swap out the textures by keyframing them instead.

I set up SDKs on my character's fingers. Everything was working fine. Fingers rotated properly from the open hand "0" position to a closed fist at the "10" position. I have the hand set up as the Driver and the fingers as the driven.
I then wanted my IK arm to work in FK, so I went into my attribute editor for IK pole vector constraint and checked on "IK/FK Control". I did a few rotations of the elbow joint and everything seemed fine.
I then went back to do some work on my hand, and when I when to change the values in my channel box to get the hand to clench, the fingers did not rotate into a fist, but rather went in all directions.
I can get the hand to work correctly intermittently (when I go back to the bind pose), so I know the correct rotation information is there. I have tried deleting history and making sure translations are not set on the hand. Would this be a gimbal or a local vs. global orientation problem?
Also, a side question: I noticed that when I built the SDKs for the fingers, I had numerous "blendWeights" created. Are these weights involved with moving the fingers between the minimum and the maximum values you set in the SDK set-up process?

I did the bones, but as you can see in the picture, the rotation not along the bone, is according to xyz, might be because i freeze them?
How can i rotate the bone accordingly? is there a way to rotate it local, and global like in Softimage?

I have set rotation limits on all of my joints in a rig. But when I move the Ik handle, the joints all rotate in however they want.
What can I do to make it so that when I move the IK handle, the joints are constrained to their individual limits?

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.

For some reason some of the joints in my character rig are displaying their local rotation axis and I am unable to turn them off. The usual Display>Transform Display>Local Rotation Axis doesn't do it. This doesn't apply to all joints, just some. This is very frustrating as it causes real clutter when rigging.

When I set up the Image based lighting in Mental Ray, and key the dome that is created to rotate in a animation, it is clearly rotating in the viewport, and when I render individual frames, it works, but when I batch render (confirming that the render range is set correctly) it renders each frame with the dome in the same position.

I am having trouble with setting rotation to other then linear for the IK Controls, the FKs work fine. Is this some limitation, or option that I am missing ? Also, the keys are displayed as diamonds instead of the usual squares, so I guess there is some lock which I cannot find.

So perhaps I'm missing something blindingly obvious, but in previous versions of Maya, I've been able to simply hit F8 and check the '?' icon to be able to go in and individually rotate Local Rotation Axis to be the way I want.
For some reason I cannot find how to do this now in 2011? I've only been able to do them using the auto-tool.
Looking for the steps I need to take to be able to manipulate the local rotation axis individually as I have in the past now?

1. Windows/Animation Editors/HumanIK/Skeleton Generator - Generate Skeleton
2. Create control rig for it.
3. Set keys to rotate shoulder down and back.
Keys are linear by default and cannot be changed, except to "stepped". Clicking Spline, Auto, etc. Doesn't change anything. Works fine on translation curves. URL....I accidentally check the "force FIK curves to linear" button? It's totally killing our animation pipeline.

i'm trying to make an object have a rotation animation.. i did this by making duplicates and rotating them different angles. When i save it and play the gif, it shows each frame show up and overlay one after the other. I want to only show one frame at a time. How do i do this? Here:

how to make this Clamp Rod to Clamp Base Spacer Turn relationship.
this is from the Clamp Project on this site: Inventor Wizard, The Clamp Lever is turning or rotating the clamp rod into the Clamp Base Spacer but I could not simulate the Thread or the Screw motion if that is the term, or the 1 or 1/2 turn of the Clamp Rod to 1 Pitch movement, plus I can't seem to put the Rod inside the Clamp Base Spacer hole when the Contact Solver is ON, maybe modeling issue on my part.

I have Autodesk inventor standard NOT the pro version. I am a Revit professional in dire need of learning Inventor. My exact steps are as follows:
1. Open assembly
2. create component - (simple wheel(cylinder) with an off axis hole in the middle so I can see if it is rotating.)
3. create component- flat surface.
4. constrain the cylinder to the flat surface via a tangent constraint
5. constrain the cylinder to the front edge of the flat surface via a mate constraint.
6. go to motion tab in constraint's, click rotation-translation, type in 10in for distance.
7.wheel does not rotate on surface like a wheel should. There is no affect of the surface on the wheel rotation.
In other words I want to get the circumference of the wheel to rotate 360 degrees as it travels pi*diameter of flat surface.

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?

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)?

When I load a set of files into RAM Player they do not always fully load. In two separate instances 1381 frames have loaded (in todays example there are 1921 frames rendered in the set).
I guessed that stopping at 1381 frames on two occasions was a bit curious and maybe thought the memory limit was not set high enough. I increased this but no change.

Is it possible to make an object, say a NurbsSphere to always be on top of the geometry in the viewport, like x-ray on joints. That way, I could use a small sphere in say the Elbow as a controller, and it could be inside the mesh but not hidden. Much like what you see here:
[URL].......
Is that really not possible?

In the expression editor, is it possible to get the position of an object at a different time ?
For example, we are at time 100, and I would like to get a given object's position when we were at time 50. Is it possible?

i created a sphere that will control the rotation of the fingers. i align the sphere to the bone so it has the same angles. the bone angle is 0,0,0 but the sphere is (15, 10.23, 2)if i freeze the sphere, the angle get 0,0,0 but they get align with the world axis as X Y Z, how can i 0,0,0 and maintain the align rotation of the bone?
in Softimage there is something call set neutral pose, only change the angle displays to zero so the animator dont have a hard time.
