This thread actually refers to the thread below, were I posted a Maya 4.5 Scenefile (which didn't work properly with Maya5).

http://sebastian-thiel.bei.t-online.de/Show1.jpg

I fixed the Bug, and the new file will definitely work with Version 5, and only with v.5.

Download the Maya5 SceneFile of the Setup (http://sebastian-thiel.bei.t-online.de/KoppSzeneMaya5.zip)


Additionally, you can download here the Maya4.5 file, which won't work on Maya 5 because they changed the way how maya interpretes MEL slightly.

Download the Maya 4.5 SceneFile (http://sebastian-thiel.bei.t-online.de/KoppSzene.zip)


I've also written a Tutorial which explains every aspect of how to work with the Scene, for Example how you can do LipSync quickly.

German Tutorial on how to work with the "Kopp" :) (http://www.gfx-scene.de/index.php4?go=tutorial&id=65)

If someone is able to understand it and wants to help me with the translation, please tell me, because I definitely will not be able and willing to do the whole work on my own.
Generally, i would consider it to be a good thing if we would translate it, because it will make things easier to get into animation with the Scene.

Sincerely yours
Byron

PS: I will only be able to answer mails weekly :(.

PS2: I was asked for my name in the last thread for credit purposes. Besides the fact, that it is written everywhere in the scenefile itsself, my name is
Sebastian Thiel.
Email is: This (Sebastian-Thiel@T-Online.de)

PS3: If you've accidently closed the AnimationInterface, you can load it againt by going into the exoression editor, show the scriptNodes, select the "StartUpScript" and click the
"test script" button.

Thanks for posting this. It reminds me a lot of the facial rig I created for my last animation, but you've gone a WHOLE lot further, with creating a windowing UI and such. I especially like the way you used new views within your UI.

Two questions:

1. Can we see a animated clip? I see you have some keys set in the file, but I'd love to see a test run or lip sync test.

2. Do you use scripts to generate the controls? It definitely seems like a lot of work to build a facial rig like this for every character.

To question One:

When you playback the Scene, you will see some sort of emotional expression. There is no lipSync in it, but it can be created quite "fast".
I wrote about this in my - german - tutorial.
When you want to see him in Action, just watch the following shortie I did for testing purposes.

Shortie, 16 MB (http://neox.gfx-scene.de/public/Byron/WKKG_LQ.wmv)

To question Two:

Yeah, the UI is one large script which is saved in the file.
And yeah, it was alot of work, but it was worth it.
And at least the UI could be transferred to every other character which was setuped in th same "style" quite fast.
For the complete setup, it took me 2.5 weeks, working three hours a day (after my civil service (>Zivildienst<).

Wow, i was waiting to see the UI, thats awesome. Thanks Byron. Did u build the whole body or just the face.
Just wondering if it was ok to do some animation with ur model. Ofcourse i would give u credit for the model and rigg. Cheers.

Very impressive. I really liked the UI you have built for the character. But I wonder if it has to be rebuilt everytime you change tabs. snipped

But on the other hand, the use of an animation window for the mouth controls is really nice.

you get 5 :thumbsup: 's

i just downloaded the scene, 1. that is a great face model im curious how did you pull back like the cheaks when he snarls and things ike that? did you use magnets? great modeling.

2. your UI controls are incredible, you were saying the script is part of the scene? is it availbable to the public? im sure i have just not read something somewere. but im sure alot of people would really dig using your UI for there facial animations. just curious were to get this script. man this is nice. very fast too.

@Levitateme:
that is a great face model im curious how did you pull back like the cheaks when he snarls and things ike that? did you use magnets?
I actually used skin and blendshapes to deform the whole head. And to create the blendshapes, I used mainly clusters and did some manual tweaks.

you were saying the script is part of the scene? is it availbable to the public?
The script is saved in a scriptNode. You can open it with the expressionEditor when you changed focus to ScriptNodes.
It is calles "StartUpScript"

@Modi: Of course you can animate him :). Everyone can do everything with him. Credit information is everywhere in the scene :).

I tried to read the tutorial through Babelfish translator - couldn't make head or tail of it - something about gerbils????:p

anyhow - I assume If I set up the blendshapes on my character with the same name as your blendshapes - then run the startup script it will create the interaface that drives them. Is this correct?

I can't work out how you are driving the eyelids - some sort of locator on curve path - how is the locator moving the mesh?

SDIT :cool:

Byron
07-25-2003, 01:32 PM
Thanks to you, SDIT :).

Perhaps well have an english tutorial in 2 or 3 weeks. Lets see :).

I already annotated the file, and I think its a good way to do it, and I am already looking foreward to get your next version of the tut.

@magilla
I assume If I set up the blendshapes on my character with the same name as your blendshapes - then run the startup script it will create the interaface that drives them. Is this correct?

No, this won't work. To understand how to use it with your own head, you have to understand how it works in detaill, so i'll will explain it to you :).

(if I had PS on this computer, I would make a schematic view of the setup, but I don't, so I have to explain ... :(. )

-> == deformed by


Mesh ->skin->blendshape->jiggle

To make the parameters work with my randomization AND with trax, I had to do a workaround: all the Parameters that are randomized are hold by a locator transform. These params included in the accoording charactersets. The Values output by these locators are taken by the randomizations expression, which applies random values. At last, this expression outputs the new value to according parameters of the deformers.
This means, when you set a key via the UI, you actually set it (in most cases) on the locaterParameters. That is why the UI is really nessecary to create an animation, or at least for creating some keys you can work with in the graphEditor or the trax then.

-- == connection

LocatorParamters -- characterSet
|
|
RandomizationExpression -- deformerParameters

So, if you want to use the UI with your own geometry/setup, you will have to create also these locators with the exact parameters on it, and the caracterSets also must have the right names, and the deformers too.
You see, it will be quite complicated to do so because there are a lot of values connected to the randomization expressions.

But if you can script a bit, you can use your own valueNames according to your own needs.


I can't work out how you are driving the eyelids - some sort of locator on curve path - how is the locator moving the mesh?

The locators are influence objects of the skin, as are the locators moving the mouthRegion. These are actually deforming an extraMesh (which is located above the original mesh) with skin, then feeding the deformed mesh into a blendShapeSlot which is always set to one. This way it was possible to have to Skins deforming the same Mesh in an easy-to-use manner.

Hi byron;

I saw that you have a second surface with the "offset" controls, they are little clusters surface constrained to a poligon surface, when they are moved the first surface offset its blendshape information (very clever), but here is my question:

How the hell do you make these clusters go to their initial position?, as they are surface contrained, they have no "real" world position but relative to that surface..., when you move and undo they don´t go to their initial state (if I do this by hand). So, wich kind of miracle did you do?

Thank´s in advance mate!

:)

Byron
10-15-2003, 12:59 PM
You can select the AddLipControls Character, select its parameters (which are the cluster transforms), and then set them to zero.

I freezed the clusters transformation when I had them in place, and then contraimed them. So every cluster has its rest position at [0,0,0]

Regards
Byron [who still has to go over the english translation ... ]

joie
10-15-2003, 05:00 PM
Ok, but if I do that on my own rig, the clusters don´t go to their initial position "exactly", then tners an error that becomes greater the more times I replay my animation.
Each time I rewind and play the error grows and at in the end their initial position doesn´t match the "real" at all.

sniifffff..., I can´t understand!

:(

Byron
10-15-2003, 06:00 PM
Unfortunately, I don't know at the moment what I exactly did since I made the kopps rigs some time ago .

joie
10-15-2003, 07:19 PM
Well, I will try again tomorrow, may be I´m wrong or doing something wrong (don´t know what since "move" isn´t anything dificult doesn´t it?

magilla
10-16-2003, 12:46 AM
If I remember correctly (my experience with clusters was also some time ago) you have to set your advanced options to "parallel" and check the relative option when you create the clusters.

Whilst I am fairly certain this is your problem the actual settings may vary for your situation, because I only used the clusters on my blendshapes - not skinned mesh - so you may have to rearrange the input order to accomodate the skincluster.

:(

I haven't downloaded or played with this face rig yet, but earlier this year I was doing some R&D on different face set-ups, and was exploring using clusters that were geometry contrained to a NURBS plane. I got the same errors you seem to be getting (you can't get the clusters to go to their reset position no matter what and it gets worse with use). It's been quite a few months, but I seem to recall that typing the following into your command line worked...

dgdirty -a

This is a MEL command that forces a given node to evaluate. Not sure where the term "dirty" comes from, but it's programmer speak for forcing data down somethings' throat I think. :D
The -a is a flag that signifies that you want to evaluate all your nodes. You can also specify nodes by name (ex: typing dgdirty "*geometryContraint*" will only force the geometry contraints in the scene to evaluate). This should pop your clusters back to their reset position. It seems Maya doesn't re-evaluate every node by default for some reason. So you have to force it. I ended up making a shelf button script that did this so that I could reset the cluster positions if they drifted too far. Thankfully when I rendered the tests the drift wasn't noticeable because the node drift hadn't built up with use.

At least I think that should work. I'd be interested in hearing if that does the trick. :)

Sorry to all for the enormous delay, thanks to SDIT (I think) who did 99% of the translation here. I'm not sure why it never made it back to the list... I think we were expecting a tutorial on constructing/reproducing the setup. This is only a guide on how to use this rig and some of the theory behind why it was made the way it was - there is still some incomprehensible stuff at the start and I have taken the liberty of removing some of the passages that tended toward gibberish after translation - sorry Byron.

I have found that the biggest hurdle in reverse engineering this rig is finding out what custom attribute is driving which blendshape and is then controlled by the expressions. Any further documentation would be greatly appreciated. I think this rig is enormously valuable and flexible and warrants some more comprehensive documentation - has anyone else made any advancements or built their own version?

KoppSetup



Ideas and goals



Animation curves are, by default, perfect - they don’t accurately represent human muscle tremors and natural variation in movement.



1.1 Randomization



The Kopp setup uses a system that introduces "imperfection" into the spline-curves. It is based on expressions. It allows a mixture from Smooth to Jittery using noise and randomisation.





1.2 Methodolgy...



For the rotation of the head a nonlinear Deformer. To these the ski lp molder and cluster belong, whereby for the rotation, the movement of the ears and the Jaw a Skin deformer was used.

Fundamental can be attained very precisely with the linear BlendShapeDeformer.

The mouth however is an extremely flexible region, simple Blendshapes fast to its borders. ClusterDeformer however by the transformation of weighted Vertices substantially more form varieties, whereby the forms cannot as be determined here exactly as with Blendshapes. For the mouth range I used thus a combination of Blendshapes and Clusters with normalized weightings - also Skin Influence Objects mentioned. This Setup permits it to steer the fundamental form over Blendshapes and leaves the option to realize deviations and exaggeration over cluster which manufactures again the singularness of the form.






1.3 Parameter Adminstration



This Setup has about 50 animatable parameters, and it is understandable how annoying it can be to have to look for each one of them again and again. Therefore I integrated them into a descriptive UI, which arranges and structures all these values appropriately. This makes fast access possible to all important parameters





2. Description of scene



2.1 The Animation Interface



When the scene is loaded, the Head Animation Controls window appears automatically. It allows to set keys, select IK Handles, control objects and switch off determined deformers easily if they are not needed. Moreover, each parameter in the UI has also a set key button.



2.2 The Front-Tab



These are the sliders that control the Frontalis and the Corrugator muscles. With them you can adjust the left, middle and right side of the forehead individually.



2.3 The Eyes Tab



Here all parameters are combined into control of the eyes:



Crowsfeet: The “strength” of the crow feet per side

Squashing:The “squeezing” of the eyes together using the Orbicularis Oculi per side

EyeLids: Lower the upper eyelid, lift the lower eyelid, close the eyelids & bias.



2.4 The Mouth Tab



Muscle control around the mouth area is handled by this tab.



Zygomatic Major: Operates the “laugh muscle” per side

Risorius: Operates a “pulling” which angles the mouth per side

TwoSided Morphs: Only contains bilateral Morphtargets .



(I recommend to try and create effects using each slider individually)



2.5 The Randomize Tab



First of allI should describe the principle of the randomization to, which is used not per MorphTarget, but per Morphtarget group. Each group summarizes topography used by Morphtargets, so that one can assign randomization at the same time in each case for several Morphtargets. This was necessary, since there would be no advantage if you had had to administer the parameter flood for each individual Morphtarget. The strength of the randomization comes from the “Regional Weight” parameter. The value of the individual morphtarget also drives the strength of the randomization applied to it. If the value is 1, it will receive the maximum “noise”, if 0, then there will be no noise. All inbetweens are interpolated in a quadratical manner. E.G: if the Frontalis is not at all active, then no randomization is used, even if FrontWeight is set to 1.



NOTICE: A Morphtarget may be never less than 0, otherwise the Expression fitted behind the randomization fails, which leads again to the fact that the Morphtargets in the Randomization group will not provide any new values. This may look as if the value was blocked. Note: When you deactivate the expression that drives the randomization, it will block out all the values it deals with, so you should never do it.

Private message to you: This is a big bad limitation that comes with expressions. They won’t pass through a value when they fail or when they are deactivated, such as using the character as a reference.





Front: Randomizes the values of Frontalis and Corrugator

Eyes: Randomizes all values of the lids, Squashing and Crowsfeet

Mouth: Randomizes the values of all TwoSidedMorphs, Risorius and Zygomatic major



Parameter:

Weight: Regional strength of the randomization

Bias: -1 = Smooth Noise, +1 = random values



Smooth Noise parameter

SpeedMultiplier: Frequency of the smoothen Noise



Other parameters



-x Boundary: Smallest possible value of the Noise

+x Boundary: Largest possible value of the Noise

Piece offset: 0 = each Morphtarget receives the same randomization values,

Higher than 0 = each Morphtarget receives own values





2.6 The Tongue Control tab



By selecting the shown clusters here, one can change the form of the tongue and also have their transformation keyed. The Locator on the right side of the image changes the length of the tongue by shifting along its Z-axis. The views on this tab can be steered like every other Maya Viewport.





Additional Mouth Controls Tab



Each individual Locator is a “device” for the appropriate mouth region. One can shift it only along the Viewplane. The Setup nevertheless in most cases makes a correct deformation possible, because the Locators can only move along the face. The Viewport always maintains its field of vision and is not manipulatable.





2.7 The Selection/ Optimize Tab



By clicking the buttons in the selection section you can use IK Handles & Control Objects for ears, eyes, jaw and head. The “Disable Section” makes it possible to use individual deformers and/or expressions purposefully. I never used this part J. Annotation: It is not recommended to disable the expressions because they will block the values they are responsible for. Unfortunately I didn’t know about that behaviour when I wrote the UI, because these “disable Expression buttons” are quite useless.

The “Jiggle” Parameter can be activated, which makes the earlobes jiggle around when he moves. I never use It either J.





Character Sets:



Character sets work with collections of parameters used in the TRAX editor. This allows you to store animation in clips and also to change these clips at will. I also added appropriate sets without these options. The TRAX editor plays a crucial role within these sets, but additionally, it also works with Kopp’s LipSync controls.



-- > BS_HeadChar: These are all the parameters used by the Blendshape Deformers

-- > HeadANDEyeMove_Char: These are the transformation parameters for the ears, the lower

jaw and the eye control contained in a head-relative area.

-- > Add_Lip_Control: These are the transformation parameters for the clusters containing

additional lip deformation.

-- > Tung_Control: These are the transformation parameters for the cluster deformers used for

the tongue.

-- > EyeLid_Char: These are all the parameters used for the lids.

-- > HeadMovement_Char: Head transformation parameters.

-- > Randomization_Char: Some select parameters used for randomization control.



Lip Sync



The LipSync section of this Setup is much faster than others because it uses the help of the TRAX Editor. At first It’s important to know that, for an absolutely puristic synchronization, only the BS_HeadChar and the HeadANDEyeMove_Char are necessary. Both possess a variety of "letter-to-clips" clips. You can find them in the Visor under Character Poses. Since I haven’t found or read any books regarding phonemes, I simply invented my own basic very basic approach.Each letter refers to a one pose (clip) in the trax



At the very beginning, you should make sure that the speech audio file is directly in the timeline (import >Audio). Scrub through it to find a starting point for each letter you need. After you accurately locate a start point, drag the correspondant ”pose”of the letter you need to Lipsync into the TRAX Editor. This will in most cases be a pose from the HeadANDEyeMove_Char menu. With the following letter/sounds:



SCH and U / B and P / M / O / F and V and W (The letter “W” when pronounced as in German)



one must also draw the same letter poses from the BS_HeadChar at the same time in the TRAX Editor, so that the mouth takes the form of these more extreme sounds appropiately.







In the particular case of the "O" sound, in the upper BS_HeadChar section, a Pose was added, for the “o-shape” of the mouth cannot be represented with clusters only.



If one plays the animation now, it becomes noticeable that the lips don’t move fluently . But even that scenario could be considered correct just like that, since it already has a feeling for the timing, which at this point should already mainly/in general be correct Next, select the poses forming each word or sentence and merge them (Edit >Merge).



If you look at the Animation Curves created by the letter-to-clips closely, you will notice that their tangents are set on Stepped Interpolation. They should be set to Spline Interpolation. After doing this for the first time, you will need to “clean” the curves, so that you can work properly afterwards. 2 steps are needed to do this:



First, the curves should be cleaned using the Curves >Simplify Curves command in the GraphEditor, which should delete keys that lay temporally very close together (time Tolerance of 0.01 in the Dense DATA mode should be enough). Then, you need to check for any keys that occupy nearly the same time . They appear if two or more “poses were overlaping. To avoid this situation, before merging the poses, you need to make sure there is at least a frame placed between them.



Afterwards, any curves that don’t have any changes in value (Static Animation Curves) should be deleted. This is very important! since they are absolutely useless and only make it more difficult to work with the TRAX Editor. Now, you can examine and, if necessary, delete all those curves manually, or you can follow these steps:



1.First, select all curves.



2.Then their input/output Connections in Hypergraph.



3.Then select all the AnimCurve Nodes directly, even if they look selected already.



4. In the Expression Editor, from the ScriptNodes select the "deleteStaticAnimCurves" Node and click on TestScript.



If everything worked fine, there should be no static curves left (NOTE: You can also create a Hotkey, to get this done faster)To do so, copy the content of the scriptNode mentioned above into a hotkey. Please refer to the Maya help to learn more about how to invoke scripts with hotkeys Now, since the curves are alright you can take it from here and go on with any further work.



Before beginning to animate something different, you should revise the LipSync animation first, until the mouth movement is really accurate. I prefer to work that way. After the LipSync, then the head movement, then everything else (eyes and everything which has to do with emotions). Working differently is Okay :).
