Impressive fan made Elsa rig

Posted on July 14, 2016

Youtube user Spiel Kind is sharing a walkthrough of his impressive fan made Frozen’s Elsa rig.

It is so impressive that even Disney temp worker Josh Sobel thought it could have been “borrowed” from Disney animation but luckily Spiel Kind documented the entire process from modeling to rigging on a CG talk thread .

He breaks down the rig by explaining how many blend shapes went into the making of that rig:

“27 blendshapes, which I divided up and/or mirrored into 90 total shapes. On top of that I also have a joint-rig though, which is responsible for the jaw/lips- and eyelid-setup.”

The explanation on CGTalk is a bit more detailed:

“It’s made up of four rigs in total. The first is a joint-rig, which drives the eyelids, eyelashes and the jaw/lip setup. Marco Giordano’s eyelid setup has been a big help for this one. The zipper setup is built after Stefan Ehrenhaus’ instructions a few pages earlier in this thread.
The second one is a blendshape setup, which drives pretty much all expressive shapes. Been using some techniques from Jason Osipa’s book Stop Staring for this one.
Both of these feed into the third setup, which is another joint-rig with just a few joints with very broad weighting … basically a poor man’s lattice.
The fourth is the eyeball setup, which works independently from the rest and only drives two joints to which the eyeballs are skinned.”

and page 5 of the CGTalk’ thread he explains what his original idea was:

“The mouth is going to be driven by a joint-rig and a blendshape-rig. The joint-rig will open the jaw and provide freeform controls for lips, nose and cheeks. The blendshape-rig will contain wide, narrow, smile, frown, lip-roll out/in/tighten, mouth up/down/left/right, upper/lower lip-puff, cheek-puff and whatever cheek-puff’s opposite is called. Each shape will be broken down into at least lefts and rights. The lip-shapes will be broken down even more and divided among the joint-rig controls with some global ones above.”

Well I guess this will tie nicely with my previous article about mouth shapes!

Mouth shapes – Chester V

Posted on July 11, 2016 
Filed Under Animation, Education, Modeling, Rigging | 3 Comments

Don’t you find it frustrating every time you join a new project to find out you have only been provided with a pose library or worse, blend shapes that only contain random mouth shapes? Haven’t people ever seen the Preston Blair book?

Preston Blair

Let’s make poorly thought out mouth shapes history!

Today I was doing a bit of cartoony animation research and came across that very enjoyable “Cloudy with a chance of Meatballs 2” behind the scene video featuring Chester V.

The camera panned very quickly through Chester V’s mouth shape library but it gave me enough frames to reverse engineer it and make a nice pose library you should share with your modeler and rigger next time you get involved in pre-production. Sorry we couldn’t see the last mouth shapes but you get the idea.

On a side note, ideally those shouldn’t be blend shapes but shapes the mouth rig and controls allow you to create and smoothly transition from and out of to the next shapes. Simple per phonem blend shapes don’t allow for smooth transition and should be reserved for low cost animated tv series.

As you can see, the mouth shapes are divided in 3 emotions or groups: Happy, Neutral and Sad where the corners move vertically in conjunction with the teeth corners and for each emotion the animators are provided with 16 shapes derived from the Preston Blair simplified phonems: M(BP), S(DTNXK), E, I, L, A, O, TH, U(Q), and F(V).

Enjoy and feel free to share and print, the file is huge enough to please everyone! ;-)

So you want to be a rigger huh? v.02

Posted on January 3, 2016 
Filed Under Animation, Education, Rigging | 7 Comments

This is an updated version of a previous post I had written 5 years ago and that I think will still be very educational after having spent 5 more years in the industry.

If you want to become a rigger/character TD and even if you are already one, you might be interested to read the following notes, you will make animators’ life easier, allowing them to pull off better shots in the same amount of time or even quicker which will, in return, make the director and producers happy.

The same way it is important for a modeler to understand part of the rigging process, a rigger should also get a grasp of the animation workflow.

So how can you become a rigger that animators are happy to work with?

 

– Start with a good attitude, ask for feedback from the animators and embrace changes, be willing to discard that crazy automated function you thought would be really cool but animators find unusable when doing actual animation work. As Eamonn Butler put it when we visited Double Negative London in 2006, character TDs work for the animators, not the other way round.

Jack-Nicholson

 

Educate yourself and stay informed by reading rigging books and dvds, read blogs! Rigging Dojo is one of my favorite blogs, they keep posting remarquable interviews. Participate to public forums where you can interact with other professionals, check other rigs! Currently I am watching Josh Sobel tutorials, it is a set of tutorial where he explains how he made the adorable Kayla rig.  Watch showreels and even students showreels! There has been instances where Interns or fresh graduates we hired were more knowledgeable than staff who had been at the company for years.

Personally, I have learnt rigging through several dvds and those should be compulsory for anyone wanting to become a good character TD so here they are:

 

Jason Schleifer shhLIFE_header2_small
Jason Schleifer “Maya Fast animation rigs”. The DVD is well over 5 years old and only 1h20 but still is a must for someone who want to be liked by his peers. Interestingly enough I just checked and Jason is now offering his educational material on a donation basis so you can pay what you think is fair.

Jason Schleifer “Animator Friendly Rigging”. That set will take few hours to go through but exposes the most important rigging concepts

Fahrenheit DVDs. I actually started with those which was really hardcore but that was a very good learning experience. I am not sure those are still available.

 

Jason Osipa stop staring

Jason Osipa stop staring

Jason Osipa “Stop starring, facial modeling and animation done right”. A new edition just came out and I should probably get that one too. Jason goes in length about facial rigging and you should definitely spend some time understanding what he is talking about.

 

You have ordered them all? Okay so while waiting for them, I want to mention few things that irritate seasoned animators when using a new rig:

 

1. Slow rigs. Rigs speed is the hot topic of 2015. Disney, in a talk given at Siggraph this year said the following: Rig speed is of paramount importance to animation pipelines. Real-time performance provides immediate feedback to artists thereby increasing the number of possible iterations and ultimately leading to higher quality animation.” 

Dreamworks and Pixar had already understood it and realtime performance was one of goal they have achieved with the recent release of Premo and Presto, their respective animation software last year. On their footsteps, Autodesk finally unlocked the full potential of modern computers with the Parallel Rig Evaluation toolset in Maya 2016.  Maya users can now  troubleshoot slowdowns and calculate mesh deformation and some deformers using all the CPU AND GPU cores present on a system, speeding up dramatically the framerate in Maya’s viewport. Make sure you read this previous article I wrote http://www.olivier-ladeuix.com/blog/2015/11/26/maya-monday-maya-2016-parallel-rig-evaluation/

504_tid_Maya_2016_Parallel_Rig

– If you are stuck with Maya 2015 and below, the old school method of speeding up rig involves replacing all expressions with nodes and create low poly or proxy version for the animators to work with. When working on body mechanics, animators don’t need the facial blend shapes or corrective shapes to be activated and when working on facial performance, body corrective blend shapes don’t need to be activated either, just a proxy version of the body to get an idea of the overall motion.

Disney Feature artist Sergi Caballer seems to have a nice feature where the animators can quickly isolate part of the body to speed up the rig. (read this great interview with Sergi on the Rigging Dojo website)

 

2. Rotation orders.
This is probably my biggest pet peeve. When creating your rig, pay special attention to rotation orders and use smart rotation orders for the limbs. By default Maya uses the default XYZ order, meaning that Z is carrying all the other axis so you want to stay away from this as often it is not the desirable order. In the situation of the head for example, it means that as soon as the animator will rotate the head in Y, X and Z will start to line up causing a gimbal lock and making it difficult for the animators to work in the graph editor. Instead by using ZXY or XZY, the lateral rotation of the head would never line up with the forward rotation. Jason Schleifer spends a chapter on rotation orders in his DVDs so please refer to it.

Rotation-order

 

3. Consistent translation direction. (thanks Richie)
Animators need to be able to animate in the graph editor to troubleshoot problems or translate a character without using the global control  so make sure your translations are consistent. If Y means up for the IK foot, it should also mean up for the hips and IK hands, same for X and Z.

 

4. GUIs As I am editing this paragraph 5 years later, it looks like Dreamworks is agreeing with me on that one so go and read: “Premo, the Dreamworks animation software“.

Personally I don’t like GUIs. Maya’s viewport is already so cluttered that I can’t see the point of having to keep looking sideway at an additional window covering, at best, a quarter of my screen when, controls could just be where they belong, on the surface of the geometry and toggled with a hotkey. Most of the time an other quarter of the screen will be covered by the pose library leaving the user with hardly enough space for camera view, perspective view and graph editor.

Frozen GUI

I tried an interesting concept a while back with a rig where instead of hitting the usual nurbs controls, you select an invisible polygon encompassing the surface of the limb. Keith Lango posted a similar setup a while ago using Zootrigger, myself I just parent constraint the Nurbs control or the joint to an invisible proxy box instead.

This could prove complex when selecting facial controls though so, fast forward to 2015, I just realised that Nurbs controls AND Geometry can be easily toggled through a script so animators don’t need GUIs as often, as long as the controls are streamlined and don’t overlap each others too much obviously (see point 9). I perfected few toggle scripts and I will share them with you in few days.

Dreamworks_apollo

 

5. IF/FK switches WITH no-pop
It is obvious that animators need IK and FK for legs and hands but you should also consider a script that would allow the animators to switch very easily from IK to FK and reverse without going back to the T pose. Some people call this IK snap, IK match. A script was provided with the goold old Norman rig to do that kind of thing

IK-FK-switch

 

6. Elbow and Knee lock. The animators should be able to lock an elbow to a table

 

7. Scaling Rigs should be scalable! Numerous time I ran into situations where we needed to scale the rigs and the rigs didn’t allow for this.

 

8. World orient/local orient switches for head, spine, arms …. Animators should be able to switch the alignment of the FK Head, neck, arms to the world or their parent by default and ideally a tool should allow to switch the parent space on the fly.

 

9. Bend bow and noddle arms. I am liking this a lot as it helps to make the rig look more organic or more cartoony in the case of noodel arms as seen below.

 

10. Cluttered viewports. Nurbs controls don’t need to cover the entire model, make them clean and simple, if possible make them invisible (cf GUI). A simple circle is more than enough for selecting controls, no need of an entire box shape especially for fingers or arms that will irremediably start overlapping and rendering impossible to select anything.

simplify-controls-and-visual-clutter
As a side note, when using circles for the fk spine, try to add an indentation at the front and back of the circle just to be able to quickly assess the offset of the spine controls. I normally take the center vertex of the nurbs circle and shift it up a bit then adjust the bezier curves like below.

Rig display simplification_Arms and Legs 02

Rotation-indicator

 

11. Non consistency in the control’s boolean channel. In boolean operations, 0 should mean “No” and 1 should mean “Yes”. ie Shoulder parent 0 should mean that the IK hand is not parented to the shoulder. You could actually do the opposite, but as long as it it consistent throughout the rig.

 

12. Set me free. Animators are artists and they might want to break an elbow, pull fingers to create smear frames, pull the lips much higher that reality would suggest in order to stylise the motion so don’t restrain the animators to what is anatomically possible, unless you want them to come up with really stiff animation.

 

13. Pole vector switches. Pole vector should be centered right in front of the knees or elbow, not closer to one or the other joint and they should have a switch to the world just so they don’t follow the orientation of the foot or IK hand at all time.

 

14. Automated overlap/bakeable simulation. Automated overlaps for secondary elements can add so much life to a rig without the animator to do much work. Think about little appendages like ears, tails, ponytails, little bit of clothing or foot straps in the case of the following Disney demo however, animators should ultimately be able to make changes to the automated result which is why the joints animation should be bakeable.

automatedOverlap

On “Messy goes to Okido”, I would first pose Messy’s tail in it’s trademark curled pose, then ran a script to simulate overlaps and would finally created a motion based on a blending of the two. This gave a life like feel that was still designed.

 

15. Autorigs/programming. In production nowadays, there isn’t much room for a TD to rig all the characters from scratch,by hand, which is why I don’t consider myself a real character TD. Instead, you might want to start automating the way you create rigs by using Mel or Python since that’s what the cool kids use those days.

When I worked at EA I had to work on several prototype games and autorigs are what offered us the ultra quick turnaround required. Rigging and skinning were so fast that we were able to start animating the same day instead of relying on weekly turnarounds. I have been a long time advocate of the AbAutorig so click the link below to see how autorigs work.

 

16. Pose and animation libraries. In production it is paramount for the rigs to be compatible with standard pose and animation library scripts like Kurt Rathjen’s Studio Library, Lionel Gallat’s PoseLib,  or the very user friendly Sal Pose Manager by Salwan Badra for 3dsmax. Pose libraries allow the animators to work with extremely complex rigs and stay “on model” which is very important when hiring junior staff and a time saver for senior animators. Believe it or not, I have worked in TV productions where the rigs weren’t compatible with those scripts and animators had to waste an incredible amount of time recreating some poses or animation from scratch and often this meant they didn’t bother.

Pose library
At AnimSquad which is often referred to as the Disney animation school since most teachers are Disney Animation Studios supervisors, we had a pose library that separated poses for when the character’s head was facing the camera, looking screen right or looking screen left as you normally use every single tertiary control to cheat the pose so it looks appealing from every angle.

 

Alright, that’s it for now and as a treat for making it so far, check out some really cool rigging showreels and “making-of” videos to get an additional creative boost:

Maya Monday – Maya 2016 parallel rig evaluation

Posted on November 26, 2015 
Filed Under Animation, Education, Rigging | 1 Comment

3dsmax TD have become increasingly envious with the release of Maya 2016 and the parallel rig evaluation toolkit allowing Maya TDs to finally use all the CPUs and GPUs cores in parallel, in order to speed up the viewport display but until now I hadn’t see such a thorough demonstration as the following one.

Have a look it is really interesting for both TDs and animators as they give some really good tips on how to speed up rigs for animators. Also, have a look at the related Rigging Dojo article which is pretty funny:

http://www.riggingdojo.com/2015/10/22/blazing-fast-character-rigs-with-maya-2016/

 

and here one new article from Autodesk

I was watching this today and couldn’t resist highlighting the following. I could watch this in loop so I made this a loop! ;-)


More seriously, I am depicting the situation as being black or white at Disney when the reality is far more complex.

Some movies like Pirates of the Caribbean are well known to rely heavily on motion capture and Disney research has published several papers featuring attempts to replace keyframe animators. The following one is particularly chilling as they are trying to prove how human motion capture can even be used to animate Non-Humanoid Characters with Human Motion Data using Pixar’s Luxo as an example. If someone called this blasphemy I would probably agree…..

“Messy goes to Okido”. Lolly’s Ice Cream van (environment rigging)

Posted on November 21, 2015 
Filed Under Animation, Character design, Comics, Education, Portfolio | Leave a Comment

At the begining of Messy goes to Okido”‘s production, our TD needed some help to rig various props and environment so I gave him a hand for few weeks and mostly for the “Taste buddies” episode. I never got credits for this but I don’t care much since I don’t really want to advertise those skills too much. I am an animator and don’t want to land rigging jobs.

Among those props was the rigging of Lolly’s Ice cream van which was a lot of fun.

It was a bit of challenge as I hadn’t done that kind of stuff in Max for a very long time but at the end of the day it didn’t take too long since I was able to use the exact same techniques I would have used in Maya. I could have spend a bit more time on some areas but TV series require a really fast turnaround unfortunately so the entire rig had to be done and tested in less than two weeks I think I remember.

If you live in UK, you can see the rig in action on the BBC Iplayer right here:

Premo, the Dreamworks animation software

Posted on July 19, 2014 
Filed Under Animation, Education | 4 Comments

Premo splahs screen

With the rise of companies like Disney, Blue Sky, Sony or Illumination Mac Guff relying entirely on the “off-the-shelf” Autodesk Maya which most animation students are familiar with, Dreamworks and Pixar had to revamp their ageing proprietary softwares to attract and retain talents. Presto for Pixar and Premo for Dreamworks seem to have now totally leapfrogged the commercial Autodesk offering by making the most of the numerous cores that current CPUs have made available for years, to the addition of on board GPUs.

Dreamworks_apollo_02
Dreamworks used to be really secretive about EMO, their home made animation software, but things are changing.

With the release of Dean DeBlois’ “How to train your dragon 2”, several videos and articles have emerged showcasing Dreamwork’s new Premo animation software running on the latest Apollo technology. The technology looks so ground breaking that the ASIFA offered Dreamworks an Ub Iwerks award at this years Annie awards.

Premo looks very fast and intuitive. Instead of having to keep a separate sizable GUI on the screen, the controls are right where you expect them to be and they magically appear when the cursor hovers over the actionable areas, signifying to the animator that the highlighted area can be animated, liberating a huge screen real estate compared to GUIs.

Additional controls like IK/FK switches I am guessing can still be accessed through the related spreadsheets when needed obviously.

This is very refreshing as the idea has been suggested for years by Keith Lango and I also relayed the information on this blog in 2010. (read the article here: You want to be a rigger huh!)

Premo also offers a dramatic speed improvement compared to Emo as animators don’t need to recalculate after each action and rig can also be played real time in the viewport without needing to use proxy models.

Don’t believe me? Watch the following videos!

Gena the Crocodile and Cheburashka

Posted on April 27, 2014 
Filed Under Animation, Education | 7 Comments

Over the years I have come across many great TV series and short films produced in the former Eastern bloc, “Pat a Mat” being one of them, but I can’t believe it took me so long to come across 1969 “Cheburashka”.

Cheburashka, is a series of four Russian stop motion shortfilms made in the early 70s, featuring Gena, a Crocodile in suit officiating at the local Zoo, and Cheburashka (“tumble” in Russian), the baby bear/monkey looking character that fell into an orange crate to wake up in a Russia town.

The short films are a pure joy to watch. The characters and accompanying music are so sweet and the stories so funny and sad at the same time that you can only empathize with the characters. As a side note, Shapoklyak, the third short film of the series is definitely the one with the darkest moments. That sequence when Cheburashka, seeing how Gena is tired from their long walk back home on the train tracks after they had their train tickets stolen and suggests Gena that instead he could carry the heavy luggages while being carried by Gena is both hilarious and heart-wrenching.

I really love that series at it reminds me of the quirkiness and tenderness of Studio AKA’s short film “Lost and Found”, the sadness of René Clements, 1952 “Forbidden games” and the great physical acting from Jacques Tati’s “Mr Hulot”. There is also some “Sitting Ducks” (the first TV show animated in 3dsmax) in it but that is probably just because we see a civilized Crocodile ;-)

Unsurprisingly the series was immensely popular in the Eastern Bloc and Cheburashka was the mascot of the Russian Olympic team several times.

What could be surprising is the fact that the series was brought to Japan by non other than legendary Japanese film director Hayao Miyazaki and Studio Ghibli. The first episode, or second one appearing in the entire compilation below, was animated by Miyasaki’s friend and inspirational director, Yuriy Norshteyn. The series gained a lot of popularity in Japan and a feature produced by both Ffango Entertoyment of South Korea and Frontier Works of Japan, supposedly came out in 2010 but I wasn’t able to find any footage of it, just the movie poster and some wonderful screenshots.

If you don’t have time to watch the four shorts, I would at least recommend watching the great pantomime animation in the following sequence.

The script probably said something like “Gena signs form and postal worker returns to his van”. What the animators added to it is just wonderful. Keep an eye on that hat, a lot of nice little touches made the characters so alive. There is definitely some Mr Hulot in there.

Here is the link to the exact sequence => postal worker deliver birthday package

And here is the the entire series with English subtitles. You definitely want to hear the original Russian song and sweet voice over work.

CGTarian Animation Half circle

Posted on February 26, 2014 
Filed Under Animation, Education | Leave a Comment

someone just pointed at a great series of videos posted by online school CGTarian. The videos feature a bunch of top Dreamworks animators (is Joe Bower at Disney or Dreamworks now?) discussing animation.

It has been a long time since I last heard a group of animators talk shop and it is really refreshing. Too bad they are not invited to comment on DVDs and Blurays anymore.

The series starts with the crucial “thumbs or no thumbs” and having Ted Ty comment makes it even more interesting.
