Maya Animation :: Interactive Skin Binding - Whole Rigging And Skinning Process
Sep 18, 2013
I'm pretty new to the whole rigging and skinning process, so in order to skin my model I've used the Interactive Skin Bind Tool (Skin>Bind Skin>Interactive Skin Bind Tool) which so far hasn't caused any problems. But when I started to modify the weighting on the geometry it appeared that the weights are reversed meaning that when using the Interactive Skin Bind Tool (Skin>Edit Smooth Skin>Interactive Skin Bind) on the left leg, I actually modify the weights on the right leg and vice versa (see image below).
(Btw, I'm using Maya2013 Students Version).

I am having a problem while rigging a series of characters modeled by my company. I have set up a reverse foot and a no-flip knee (Art of Rigging Vol. 1's method). The leg functions properly, my attributes work fine, but I am not using a pole vector for the knee and when I raise the foot control the knee pops out to the side.
I never use a pole vector, I use a knee twist attribute. However, even after experimenting with a simple pole vector constraint on the ankle/leg IK to a locator, this still happens. I have had to counter animate the knee on the last 4 characters because of this.
Unfortunately, these models aren't in a true T-pose, the legs are wider than the hips, and the toes and knees are pointed outward. I create the bones, then orient the rotation down the chain so the orientation is correct--- I'm wondering if this is happening because the leg bones aren't going straight up and down, but more trying to follow the contours of the model. And no matter if I use a no-flip knee, a pole vector, or what, the knee STILL pops out to the side. It's making animating these models a pain in the butt because I'm constantly counter animating the knee so the leg is straight on simple things like run cycles.

I'm trying to use the same interactive skin capsules for multiple characters. Because the characters have different geometry I can't simply copy the weights. Is there some way to copy the capsules used for interactive skinning to a new model?

I'm wanting to know the best way to make different game outfits for a character. I want to be able to switch out between a couple different torsos and still have the same head model and rigging with animations still working.
I'm not sure if this is the best way or not but I detached a cylinder into two separate pieces.
Then I skinned and weight painted one half of the cylinder, weight painting the seam 50% to both bones and decreased that amount as I went father away from the seam. Then doing the same thing to the other half of the cylinder.
For example if this was the game character I would detach his arms, legs, and head from his torso and do the same thing I did with the cylinder.
I've included a link to a video of the cylinder bending.

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'm having tons of trouble with the hair system for a character I've made. One that I'm very stumped on is for the rigging. I have a skull cap with hair on it and then the character separate. I have created a skeleton with which I want to smooth bind to the skin. While the smooth bind seems to be working, I'm having issues with the hair not following the global skeleton when I move it. The character herself moves, but her hair stays put and I don't know where to go from here to make her hair follow. I have tried combining the skull cap and character. I have tried grouping the skull cap and character. I have tried just about everything, but the hair will not follow. The most I could do was make the follicles and skull cap move, but not the hair. Any way to get the hair constraints to move along with the hair system after it has been binded, that would be great too as I have used hair constraints to form her hairstyle.

So I'm trying to rig this arm to bend, but with more "bow" than "bend", if you get what i mean..
I thought I could create an IK handle, but at the moment it bends only at 1 joint. I would like it to bend further up the arm,in an arc shape.

I need to rig two objects together that follow one another the same way a train car or truck-trailer rig would. I've Googled for days and have tried several different constraint and skeleton options but haven;t been able to figure this out yet.

I'm currently rigging a character who is standing in a relaxed pose. Everything works fine until I get to the hands. The hands are also relaxed and a bit bent which makes it a bit hard to get the joints exactly where I want them. I have to jump between every viewport view to tweak the joints.. and it's rather tedious. I've read on several animation forums that people prefer to rig a character in relaxed position and that the T-pose is pretty much outdated. I watched a video from Naughty Dogs (the studio behind Uncharted game-series) and apparently they rig their characters in relaxed pose.

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 almost done with my model. He is in a naked state for the sake of making sure the anatomy is correct. I am preparing to rig, texture, and animate him. I plan on modeling the shirt and pants separate and use Maya's nCloth for those. I have also modeled glasses that are a completely separate mesh that will need to follow every movement of the head of my model.
Here is my issue, I am puzzled on how to model my shoes and socks.
1) Should i model them as part of the legs to eliminate further animation?
2) Should I model thee shoes and socks separate from the legs?
way to form a hierarchy where i can model everything individually and then make the main body rig a parent to everything secondary (shoes, socks, glasses, etc...)?

I am having issues with rigging a simple character in Maya 2013. I was able to set up the joints and the skeleton but when I move the joints to start animating, the model moves separatly from the skeleton. It seems to be moving in the same direction but exponentially more than the skeleton, creating separation between the model and the skeleton. I am new to rigging and was going off the tutorial and am stuck at this point.

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.

I am currently trying to bind the skin for a character using a rig created from a Digital Tutors Tutorial. The rig I've build seems to be working fine however when I created the smooth skin bind the thighs collapse when the leg is raised. I've tried fixing it using the interactive skin weight tool but it doesn't seem to make any difference. i have included pictures of a quick render as well as the weight influence of the knee and hip joints.

couple of days ago i finished rigging, positionned my character in a nice pose for a render then closed maya. Foward a couple of days, now when i move my rig the character is not following it, he stays in the same pose as he was like if he was frozen.

We're having issues saving and importing skin weights, and mirroring these weights on our character meshes because our characters have some geometry that has been combined into their mesh (like eyebrows, fake spikey hair, eyelashes, etc)
Maya seems to take the UV's for all the combined meshes and stack layer them into the 0-1 space in the UV editor. When we save skin weights for the main mesh, the weighting maps are all messed up and useless for importing because they are based on UV's that are supposed to be clean and dedicated only to the main mesh.
how to save weights and mirror weights for meshes like ours?

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.

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.

recently ran into some trouble when rigging a character. I selected the character geometry, added a skin modifier, and attached all the CAT bones and muscles that I had created for my character.
The problem begins when I try to rotate the CAT bones in the rig. If I rotate the torso bone for instance, and then press undo, the mesh sometimes pops back but the CAT bones remain in place.
Another issue is that after I reload one of my earlier saves in which I had applied a skin modifier, the rig becomes highly distorted.

I've been playing with Scene Referencing, and have a question about skinning. Is the ability to bind a mesh that is part of an Assembly Reference something that will be coming in a future release? I'd like to be able to bind both a high-poly and a low-poly mesh to one rig using scene assembly. That way I can swap armor parts, weapons, etc on one rig without cutting/pasting animation between rigs.
I've attached a picture of a sample of what I'm referring to. If that isn't workable, any other workflow that is comparable?

I rigged a model and everything was working fine. I then started going into the blocking phase of some animation I was going to do with it. After a review it was requested that I put some extra bit of rigging on the model. We basically wanted to have the ability to grab both eyes with a controller and pull them around positionally and have the bit of skin they cover follow along with the eyes. So I dropped in some bpones where the eyes are, made the controller bits, linked everything up, so far so good. My problem comes when I try to skin the mesh to the new bones I just dropped in. The verts I have selected, even when given a weight of .1 seem to shoot forward in space. They dont seem to be respecting the bones current position that they are being weighted to.
I fear this may have something to do with the fact that I have animation in this scene which I know isnt ideal but were doing a series of xreffing so our master rig file also contains our master animation data. Seperate files are saved out as backups but as far as working files, yeah, its all in there. So could this be whats causing my verts to jump forward in space when I am skinning a bone that they currently are at its position? Or perhaps some errant transform? In the image I have selected the two rings beneath his eyes and given them a weight of .1. As you can see the verts are shooting out in front of the mesh when they should be staying in place at the eye bone I am trying to skin them to.

For some reason when I use my Paint Skin weights tool, the mesh does not go into a grey scale type shader. Instead, the textured model is still displayed instead of the black and doesn't display weight values in the greyscale I'm used to.
Did I mess up settings somewhere? I know I'm in Paint Skin Weights tool because I can see the bones when it goes into Xray. I can open other scene files and can view the weights just fine.
Note: I have tried the following fixes: copied the mesh into a new scene, made sure it wasn't a subdiv shape.
I am using Maya 2010

I am in the process of skinning a character and I was wondering if Max had a feature/option/button that allows you to select all the verts that are currently being influenced by the particular bone you currently have selected? It seems like a feature like that would make setting up the blends between bones a lot easier then having to select all the verts in question each time and then additional verts that you are wanting to weight to.

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

How can i rig a non spherical Eye? At this very moment I have and sphere, wich I deformed with an FFD Box.
But if i rotare the eye the pupil doesn't stay round, wich makes scence to me, but i can't think about an possibility to avoid that...
I attached my test max file. You maybe want to have a look at it.

A way to rig a chair and have the casters follow?
Basically, I have one dummy that controls the position and rotation of the chair. As the Chair goes forward or backward, the casters will need to swivel around and would be following the chair from behind. Likewise, when the chair rotates, the casters would swivel and follow from behind. Would this be Wire Parameters?

How do I constrain a child object to only Rotate when its Parent Rotates rather than follow it. My attachment should hopefully explain this better.
Also will constraining this be included when exporting the file to an FBX?
