3ds Max Animation :: Modifying Bone Size In A Biped?
Jan 24, 2014
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 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.

I have a list of motion capture, those mocap didn't track the fingers so the hands are always opened. In some of these mocap I need the biped hand to be closed. I've been looking for a solution for about a day now. I think I'm in the good way which is to create a biped layer animation where the hands are closed and link the hands of that layer to the original layer. so I would be able to save that layer and apply it to every mocap animation that need to be readjusted. The only problem is that I'm not sure if it's the better way and I don't know the procedure.

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 need a biped to stay still in an animation for a few frames. What I'm doing is say I copy a pose from frame 10, then I want the biped to remain still until frame 40. So I paste the pose there and fix the feet keys. As a result the biped position is the same in both frames, but when I play the animation I get some unwanted rotations between these frames I can't get rid of.

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'm having a strange problem using loaded .BIP file on a biped in 3D studio Max. The biped doesn't allow me to make rotation and translation changes on the head, attached bones and the feet and hands. This only occurs in the viewport!
Altering the rotation and translation keys in the biped workbench editor works fine. but obviously not very practical . I already tried to add a new layer above the current biped animation. But without successful results Also exporting the animation to a .BIP file and reassign it to the biped didn't work.
One thing I have done is using the motion flow system. After finalizing the animation I created an unified motion which is available in the flowgraph options. In order to convert the motion flow structure to real keys.

New Retime tool feature in Max 2013; when i tried with biped animation, its not working, but it works with every other object. Workflow which i followed:
1.Selected all the biped parts.
2.Open curve editor. (it shows all the animation keys and curves)
3.Applied Retime All (Retime tools shows up)
4.Double clicked to create start and end marker.
5.Now, when i move any of the retime marker, the keys are not responding, only the marker moves and there is no change in animation timing too. everything stays same.
does the retime tool is not applicable for biped. I tried the same procedure with other animated objects. It works fine.

When it comes to adding a biped into the centre of my character model how does it work? (I am not that far in my college project but am a I am worried)Does the biped attach to I ndividual pieces of the model ( hands, head...etc) and they have to be attached individually Or can the biped work with a single object ( all the pieces attached) and still be able to move individual elements like the hands or feet I am getting worried as I need to start this bit soon

I'd like scale my biped animation. I have 200 frame mocap animation, all frame has keys. I want scale it to 72 frame. I found how can I scale the keys, is ok, but after scaling the bip01 bone jump there and back.

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 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 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 animating a skeleton. As a result, I'm not using physique-- I'm just connecting different mesh objects to different bones in the biped, and I'm good to go.
Here's my issue: I don't want my biped inside my mesh. I want to stick it off to the side somewhere where it's not interfering with my actual mesh, and I can do my links easily by just dragging over to them.
Naturally, when I do this, things rotate around the biped's pivot point rather than where I want them.
Is there any way to offset the biped-- just for interaction, and visually? I just want it outside of my mesh so I can animate the biped without having to look at it all merged up with my mesh.

I'm working on a project where I need to duplicate all animated sequences for both a male and female character. I currently have two biped rigged characters. I animate one, save the .bip animation file and then load into the other. I check the boxes for "Load max Objects" as I have some objects (like a glass of water) set as an IK pivot object. It loads those into the new scene along with the new pose, but the pose goes wrong, thought just with the arms (which are incidentally the only parts that have a seperate object as an IK pivot object.)
Here's a screenshot to show what I mean:
This incorrect animation happens whether the .bip animation file I save is loaded into the other character or loaded into the same character in it's original T-pose.

I have a Biped which had a number of .BIP files added then mixed down. All of these have been removed however there are 2 which are still hanging around and can not find any reference to them anywhere. maybe a script exist which removes all of these?

I am trying to find out if it is possible to hide parts of a mesh while I skin certain parts of a mesh using biped . Here is what I have tried. Below my skin modifier on my stack is my edit mesh. I open up edit mesh and select the faces I would like to hide and hide them .Then I return to my skin modifier and skin parts of my mesh. but then I reliased that my biped is no longer skinned to my mesh if I hide a porition of the mesh. Even When I unhide the faces the mesh is no longer skinned to the biped. The biped moves but my mesh no longer follows. I tried deleting the skinned biped bones on the skin modifier and re adding them but it still did not do anything.
I know there must be a way to hide parts while you skin. By the way I am using MAX10

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.

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?

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.

Is there a way to get the position parameters for a Biped COM to play with in Track View? All I get are the rotation parameters.
If that's not possible I'd like to know a way to manipulate the animation between 2 keyframes. The TCB parameters don't seem to be working for this.

Is there a way to quickly assign all the Skin vertices with 0.0 weight to their correct biped link?
In my attachment there is about 50 vertices remaining having already corrected about 50 by hand. This is not a problem to do by hand however I have 20 more characters to modify after this any scripts/tips etc.

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.

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?
