Facial Animation Rig

Version:
1.4Create a complete head rig, with facial animation controls as recommended by Jason Osipa in his book 'Stop Staring'. Starting just with a head mesh, create bones for jaw, head,neck and eyelids. Also create a couple of spline controls for the eyes and the chin. Running the 'eyerig' script creates a rollout with pick buttons for all needed bones and meshes, then sets up the eye and head rigs, as well as placing a skin modifier on the mesh, with the required bones added, ready for vertex weighting. The rig also caters for 'fleshy eyelids' that move with the eye.
Running then the 'facial_ control_system_developed' script creates the on screen controls necessary for nuanced facial animation and lipsync, using opposing sets of morph targets in order to avoid clashing. I also include a couple of scripts I found useful in making the morph targets - 'split morph' and 'copy morph'. Split morph is a very simple script that derives a right and left hand set of morph targets from one symmetrical morph, such as can easily be created in ZBrush, for example.
Copy morph transfers sets of morph targets between meshes.
Three outer rectangle splines - one for upper face, one for lower face, and a general one which has all the parameters are stored in 3 PEN attribute holders , for storing poses,visemes etc. and making shapes easily configurable, reusable from mesh to mesh. Also possible is the use of motion capture devices on the spline ctrls
Further usage notes and explanations are included in the comments for each script.

I cannot open
I cannot open unrigged_face_start.max in my max2008x64. I downloaded this twice. It says "File open failed" :(
Anyone with the same problem?
Yes i have the same problem
Yes i have the same problem to.
I have re-uploaded the file.
I have re-uploaded the file. I am using max 2009 x64 so unfortunately you would need this version to view the start file. However the max scripts will still run on any version post max8.
Also there was a small problem in the eyerig script which I have fixed and re-uploaded.
Hi... the eye rig now
Hi...
the eye rig now loads...but when i finish selecting all the bones and splines...i click create eye rig, and i get an unknown exception error... and the maxscript window pops out highlighting
"skinOps.addBone headsup.modifiers[#Skin] headbone 0"
using max2009 64bit
thx
Looks good

Hmm, Occassionally I got
Hmm,
Occassionally I got this error because of the skin constructor not finding the bones,...this step
is not strictly necessary , I put it there to save time adding bones to the skin modifier,more or les as an afterthought, but when I got that error, I simply highlighted that part of the script, pressed numeric key pad enter and voila! it did it.So go figure. However, if you want to comment out the line dealing with the skin modifier,at the bottom of the eyerig script, feel free to do so. Also, simply running the script again works, although it's a little tedious having to pick all those bones again.
Also you might try creating a function dealing with this step and place it at the top of the roll out code, then call it at the end.I guess I should do that myself and I will but i'm a little burnt out at the moment.
I believe you can still run 'facial rig developed' anyway, which is the 'meat' of this submission.
I have added three more tex
I have added three more tex files, whihc explain the best way to make the required assymetrical morph targets. Especially the lip morphs, which I found tricky.
Hi I tried the developed
Hi
I tried the developed script...on your file unrigged_face_start...
it created the UI...but it gave me another error
I ran the script...i picked the head as required...did not pick teeth or tongue as there is not one...clicked "create facial ui"
error "Unknown Property: "Morpher" in undefined
Im not a scripter..so i dunno what that is...:P:P
oh and the UI doenst do anything...

ok, Sorry about this. I will
ok,
Sorry about this. I will have another look at the start file, but have you uploaded the new version?
For me, the whole thing works perfectly, but I will double check everything. If the teeth and tonque morphs aren't there, you are using an old version of the start file.
It won't work unless all morphs are present.
I have a check morph function which you should run before clicking create rig. Thank you for your patience.
Oh - I will fix the skin op problem in eyerig script and re-upload in the next 24 hours.
I have just re-uploaded the
I have just re-uploaded the start file to make sure it is the latest there. If you can not find the tonque and teeth morphs, then you have the old version. Re-download the start file if this is the case.
The original eyerig script is fixed for the skin ops, and is now called eyerigextra. I have tested everything and both scripts work as intended.
In production, the mesh would have a morpher material applied for displacement and normal maps to create brow wrinkles etc. In fact, the morpher material is an integral part of the morph target modifier and works hand in glove with it. This is very easy and natural to set up.
The script is a proof of-concept for the max version of this very useful professional rig Osipa designed for maya - it's not a toy- like digimation product for making funny faces. All the functionality of his maya rig is here including the eyelid part of the rig, which allows for squints and 'fleshy' eyelids.
Please note however, that the mesh and morphs are for testing purposes only - they are not meant to depict production -ready meshes.
The teeth morphs, for example, are just there to show the hook-up code works - please ignore the shortcomings there. You should use your own meshes and morph targets, the production techniques for which I have provided notes.
Hi!:) Sorry i havent been
Hi!:)
Sorry i havent been around..i will re donwload all to check
and let u know asap
