3ds Max Animation :: Lock Rotation Axis For IK Bone System?
Aug 23, 2013
I've created a mech robot and now I want to create a rig for it. But the problem is, that none of the joints are 'ball and socket joints'. So the joints can only rotate in one dimension, like a typical mechanical joint. My first solution was simply locking two out of three rotation axis for the bones and this works fine for FK animation. For IK animation however, it doesn't work. The locks are simply ignored.Is there any way to lock a rotation axis for an IK bone system?

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'm rigging a shoulder pad to a biped and I'd like it to only rotate on one axis. Google hasn't been that useful, and I hope I don't need scripting for this kind of minor thing. I'm rather new to 3Ds Max Design but I'm learning fast and liking it so far!
I've attached what I want to effectively accomplish. I'm looking for a way to lock the z-axis of the object with the upper arm's z-axis.
EDIT: Reduced picture size.

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?

I currently have a model made of a few different meshes (head, body, upper/lower arms etc...) which I have linked together. I primarily animated by rotating the joints of the model, but it just isn't cutting it anymore.
Is there anyway I can create a bone system that uses the meshes as the "bones"? I'd like to be able to do that so I can change the models for every part of the robot seperately in my game by changing the mesh associated with the bone. I've tried searching google and youtube but I'm not really sure what to search for.

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.

Any way to do the skin conversion to muscle system WITHOUT converting every single joint to a polygon bone object. I'd prefer to manually create the muscle bone objects from only the joints I plan to use for the muscle system, and then do the skin conversion using only those joints already converted. Basically, I only need a few muscles in this system and therefore only need a few polygon bone objects, but as far I can tell, there is only one way to do the skin conversion and it automatically converts every joint that the skin is attached to.

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.

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

I am in the process of doing an animation for a PPT presentation. I have several series of images like the one attached which represents a card with some holes in it flat (if you like) on the desktop. I'd like to rotate the image 30 degrees about its vertical axis giving the (isometric) impression that it faces to the right (or left). Is there a functionality in Paint.NET which can achieve this?

I have a figure with an oxygen mask attached to his face and an air pipe leading from the mask to a tank on his chest. I've added bones coming from the head for the mask and pipe and I need to fix the bone at the end of the pipe to the tank so that when he moves his head the pipe flexs but the end doesn't move from the tank. Hopefully that is clear
Is there a way to constrain the end of the pipe bone to possibly the rib cage bone? So they move together? With the pipe being flexible in between.

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?

Is there any way I can extract the rotation of a block relative to the yz axis and xy axis. I can extract the insertion point and xy rotation but not the yz and xz.

i try to make an animation. I create a cylinder and i want to rotate it by longitudinal axis. i click 'components', select the cylinder and after i click 'position' to select the axis that axis system appears in the right side of the cylinder not in the middle. If i continue whit this settings the cylinder will rotate by a circle not by his longitudinal axis. How can i move that axis sistem in the middle of the cylinder? I can drag it but can't place it exactly in the middle.

I have an old figure that is high poly and skinned to a bone skeleton. I want to rig it to a CAT rig for some of its quick animation features. Ultimately I want to be able to export the model into UDK to learn 3d demonstration and game development.
I have aligned a CAT rig to match the bones of the old figure. If I select and link the bones to the respective bones in CAT rig I can get the figure to animate perfectly and quickly, but when I export to the UDK through FBX the figure is severely distorted. I've found that the old rig needed to match the rotational axis order to the new CAT rig bones which worked a little on several of the limbs, but the initial translation of each bone does not get transferred giving an offset to the bones that still distorts the figure.
I want to rig the character with the CAT, but the figure uses painted vertex weights. I could spend an immense amount of time to try and replicate the quality done by the vertex weights, but if there is a tool or script that could speed up the process. I am looking for a tool that would be able to transfer vertex weights between bones. Ideally I'm looking for a workflow like so
1. Load figure
2. Add CAT bones to skin
3. Edit envelopes
4. Select bones or vertexes to copy
5. Copy vertex weights
6. Select bone destination
7. Paste vertex weights
The paste should then delete the influence on the original bone to complete the process.
I've seen something very similar to what I've been needing from this artist that goes by the name of Sun Dawei. A search for "Dawei Sun transfer vertex skin weight" minus the quotes gives you a video that would visually show the process I'm looking for. I don't know the policy on putting links for videos that I don't own so I won't put the actual link here.
I would like the script that Sun Dawei developed, but I could not find a download for it. He might have wanted to keep his work private, so I'll respect that.

I have already done a smooth bind on my mesh and painted weight maps. But then I realized I need to add a bone into the joint chain. It is on an extremity. Is there a way to add a bone in after binding without having to unbind and redo weightmaps?

I have created a model of an alien, and I wish to rig it upto a biped. The reason I would like to be rigged to a biped opposed from using bones is because I wish to apply motion capture files to the biped from iPi Mocap.
However, the problem I am having at the moment is that because my model is an unorthodox shape, and does not follow the figure of a human, is how do I modify and change the sizes of each individual bone? I've tried using the scale tool on the bones to no avail, as well as searching through the options. Are there values I can change to make them bigger?
In the picture I have attached, you can see that the hip on the biped, is significantly higher than the model, meaning that when it comes time to skin the model, it'll think that the aliens body are part of the legs.

I am having trouble rigging my character using the bone systems in 3 ds max. I boned out the front leg and cloned the bones for the other front leg, and that went well. the problem came when i tried to create the bones for the back legs. When i try to make the bones, they will only go on the x and y axis. I think the z axis is constrained somehow.

I made and rigged some bones to animate a mech a modelled. However, after rigging I realised that one of the bones was too short, effectively making the 'thigh' pivot around an area lower than the 'hip'.
Is there a way of lengthening the bone, or do I have to delete it all and start again?

So i was skinning my 3d model and when i started keyframing different leg poses this is what happened to my bones in the leg.
How do fix this without really having to reskin the whole model

I am currently working on a project that requires me to keep an object centered between a biped's hands (like a floating fireball or a box). I need to be able to move the hands around and keep the bone averaged between them. The position and rotation need to be averaged for the bone, but not scale.

Best way to keep clusters in alignment with bone rigging. I'm trying to parent clusters that control facial movements to the head bone of my skeleton so as when I move my character about the clusters retain there position in relationship to the face.

I am trying to rig a character, and when I place the bones with the joint toot they are very small. So I went into the tool settings and upsized the radius for all of the types of bones. But then when I go to make the bone again it is still the same small size.

In the timeline panel in CS6 EXTENDED, you have a video feature, where you can animate three things:
Position Style Opacity
What I would like to know, is: How can I animate rotation of a layer? I want to rotate my layer at an angle and animate it. But when I rotate, the first animation frame is also rotated, resulting in NO animation between the frames.

Is there a way to assign just specific vertices to a bone by selecting a separate part of an object? Like for example, I have a model of a gun which I'm trying to rig now and this gun has two barrels, one obove the other, and each of this barrel needs to be assign to a different bone. Those bones are there, but the problem is that certain parts (vertices) of second barrel are assigned as well to the second bone, which is incorrect. How do I select only part (an element) of an object and assign it to the bone?
