3ds Max Animation :: Export Skin And Morph Based Rig To Test Out In Unity
Nov 22, 2013
What I'm attempting to do is export a Skin and Morph based rig to test out in Unity. The bone and morph targets come into Unity but the actual morph animation didn't. I checked the controllers responsible and it appears that the curves driven by the Reaction Manager don't get baked when exporting to .fbx.
Now I suppose I can bake them myself to something .fbx understands before export but I can't seem to find a way to simply take the animation curves for the morph channels and bake it down.
I really would like to get Morph Targets working in Unity but this silly problem is preventing me from doing so.

I have an issue with the skin morph modifier. I have morphed the bend in the knee and fixed the crease behind the knee on the left leg. When I tried to mirror it over to the right leg, it goes crazy. I found out that the morph preview verts on the left leg are not staying on the model as the should be when I bend the knee. The model is perfectly symmetrical so the offset doesn't need to be changed and the mirror threshold doesn't seem to be doing anything to work.
skinMorph1: Both leg straight
skinMorph2: left leg bent with verts off of the model
skinMorph3: right leg bent with mirrored verts from left leg

The problem I'm having with Skin Morph is that it's skewing my vertices side-to-side locally.
I'm using Skin Morph to better preserve the volume around the two joints of each finger of my hand model (See Arm1).
The two skin morph targets were created for the index finger while it was in the same position as the second image (Arm2).
I repeated this process, creating skin morph targets for the other two joints on the three other fingers and on the thumb.
The problem comes when I rotate the knuckle joint in any axis, in the third image (Arm3) I've rotated the knuckle downwards and you can see the vertices affected by the Skin Morph modifier have skewed to the left. When I turn the modifier off the vertices go back to their original position - so the problem isn't being caused by something like non-uniform scaling of my model (I reset the transforms before skinning).
The fourth image (Arm4) just shows the basic child/parent relationship that I've setup with the Bones and SplineShapes.
The fifth images show the (perhaps strange) position of the Driver Bone Matrix and the Morph Bone Matrix which could be constributing to the problem somehow.
I've uploaded the file so that you can explore my scene. armrigskinmorphproblems.zip

I want to morph an object based upon a look at constraint.
That is, assume object (A) has a look at constraint target object (B).
I want to morph object (C) to (A), based upon movement of (B).
Is this possible ?

I have created an object (Tube012) that i am trying to use as a rotational control mechanism / rig to move some vertices (morphed spline 012) through a series of progressive morph targets.
i have created morph targets that work as key framed morphs but when i change these to progressive morphs and try to drive with an expression nothing is happening.
The work i am doing is largely based on the great work of Ruramuq and Harvey from the thread "Rigging a wave (3D's Max)" Not sure why. I have file from Ruramuq and have tried to replicate his technique. Everything works well in his file so all i need to do is replicate. The answer is in here but i cant tell what the difference is between his and mine.

I have a simple object that I want to morph between the original and a smaller version of the same thing.
I made two copies "start" and "finish". I then selected the original part and then Create/Compound objects/Morph. Under "Pick targets" I ticked "Copy" and then selected the first target ("start") and the second target ("finish") ready to set animation keys.
When I select the first target the original part moves randomly to another position in the scene. If I change the pivot point of the object it changes where it moves to but still moves it somewhere else in the scene?
If I move the original part back to the correct location the animation still has incorrect movement?

I'm trying to animate a moving rope based on simulation data. I know how to import my motion data for individual objects.I've seen lots of tutorials where one uses simulations or soft bodies with IK in order to create a rope. how to use all these features and I want the rope to follow my coordinates exactly. I was hoping I could do something like the following:
1. create points in Maya which correspond to my data points
2. connect the points with a curve
3. loft a circle using the curve as a path in order to make a rope
4. move the points. due to History, the rope position is updated
Is there a way to do something like this in Maya? I've tried, and it looks like ep points do not have key-able channel data, so I can't create animations for them separately. I'm using .mov data file imports to generate x, y, and z motion keys for the points.

A: Can I export skinning information from one mesh to another. I have two identical versions of the character except I forgot to weld some verts on the model before skinning. Can I weld the verts and then export > import the skinning data? If so how?
B: I have someone working on some animation for me in CAT, I have since made some minor changes to the CAT rig (increased width of chest bones, that is all). I also changed all the skinning. Is it possible to export the animation data and load it onto an almost identical CAT rig? If so how?
I have max 2011 an 2012.

I'm currently trying to set up bones in my character. What are some good resources for fixing skin weights, painting skin weights, and other weighting techniques. My problem is that when i bend a finger it squishes too much at the inside of the joint.

Is it at all a good idea to go about to skin multiple objects for your character?...or is it better to make it a single mesh?
if its practicable whats are the "things to do" to go about it in the right direction. ..instanced skin modifier? OR unique skin for each objects?
does it make any difference if i attach the objects? or keeping them separate as far as instanced skin modifier is concerned? (not making single mesh by welding vertices)
specifically speaking about the character i am working on ...it has:
a. head mesh
b. a scarf mesh
c. hand mesh (till their elbows)
d. body/ trenchcoat mesh
e. trousers
f. shoes mesh
g. shoelaces and eyehole rings mesh
NOTE:
i at least need the trenchcoat to be a seperate mesh as i want to apply APEX on it later. (the APEX tut on youtube indicates the trenchcoat is a seperate mesh.)
PROBLEM:
i tried to use a instanced skin modifier, however the scarf head and trenchcoat and the head where they should be together gets messed up when i check with some basic check poses.

I've migrated from Maya to 3ds Max for character animation and was wondering - When I apply a skin modifier then go to 'Edit envelopes' - is there an equivalent to maya's artisan interface? i.e. Can I paint weights with a brush rather than vertex by vertex or entering numbers?

I want to just bend the legs on a deer so I put some bones in, and added a skin modifier. I am having trouble with some vertices being affected above the leg joint. I can't seem to select them to change the weights. I have checked off "select Vertices" on the top area of the modifiy panel. I've posted an image below where you can see my problem of the bottom of the belly being affected by the leg.

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?

Got this low-poly model here. I created some bones for it and inserted them into the mesh. But when I use the Skin Modifier into it, and use the 'add' button under "Parameters". No bones appear in the list?

I have a single-mesh model, pre-rigged and textured. I am trying to export it into a format which has a bone-limit of 59 bones per mesh. This model, however, has over 100 bones.
I'm really not very good at doing rigging from scratch; someone else rigged this for me. I need to split up the mesh, so the model meets the less-than-59-bones-per-mesh rule.
Is there a way to do this without destroying the skin modifier, and having to re-skin the whole thing? I'd like it to end up as several meshes, which all work as one in terms of rigging.

Skin modifer, skelleton has moved outside the mesh.
I flick the light on and off on skin modifier, when its off the skelleton fits the model perfectly and when it,s on the hand and arm has been liftet outside the skel.

is there any way to delete a mesh based on frame? I have an object that fades to nothing after it's use is done, at frame 3000 say, and I was wondering if there was a way to just delete the mesh after that. Normally I would use vol select and a deletemesh modifier, but those seem to mess with the Pathdeform WSM a fair amount. This is really more for the sake of optimization, since that's around a million polygons that are still there, and making my poly count look silly high. Currently using the visibility track to make it vanish.

I created a rig in MAX 32bit but recently loaded 64 bit MAX but now when I choose the skin modifier/edit envelopes, I cannot choose bones to edit. The interface just flashes and I am not able to select verts on the mesh. I had originally used the weight tool to change the weights of each vert on the mesh, now it doesn't work at all.

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?

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.

I have tried multiple times now to download a trial for Photoshop CS6 Extended. Everyone says that the CS6 trial is already the extended version and only changes based on your serial number at purchase but every time I try to open a video project of mine it says "This file contains a timeline-based animation (Photoshop Extended only)"

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).

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 doing some animations involving sine waves, and I can make an expression that controls the translation of an object such that it travels along the path of a sine wave, but I can't figure out how to dynamically create an editable sine wave curve.
Is there a way to have Maya generate a curve based upon the path that an object travels upon?
For instance I have a sphere that is moving along the X axis with time, and also moving up and down on the Z axis back and forth. I would like to make an editable curve object of this path of motion.
I can see in Maya 2012 we will have motion trails where we can see the actual path an object is moving along, and that we will be able to interact with this path to alter the animation, but what if we could take that path and make it an actual curve or NURBS object?

I'm trying to determine how to change the color of an object based upon a custom attribute slider. It would only need to change between 2 colors. I know this can be done by simply autokeying but using a slider would be more useful for my situation.
Is there a way to do this? I've been playing with wiring a simple cube's material but am not sure how to do this.

Need to control playback of the animation based on an anchor in the web page. When the anchor comes into the browser viewport, it would trigger play, pause or stop.
And ... to control the flow/direction of the animation playback based on scroll direction.
The setup:
I would like to have the playback direction for Edge animations placed in a web page, to follow the web Surfer's scrolling direction.
Scrolling down or right, Animation plays forward.
Scrolling up or left, Animation direction plays backwards,
But, that's not all ... I would like to combine the scroll direction sync with ... Anchors
Image if you will:
Multiple Edge animations are placed at various positions on a web page.
Autoplay for each is turned off.
Wish to individually control the playback functions for each animation. - Start - Stop - Pause.
Wish to trigger their playback relative to when an associated anchor (becomes visible / invisible) is inside or outside, of the browser view port.
Sounding complicated?
I put up a web page diagram to illustrate the functions. [URL]....
