Eyes vocabulary

After few month working on Okido, I felt there was a lack of consistency between all the animators and decided to make a compilation of examples from my favourite animated movies.

Cartoony eyes are usually so massive that unlike realistic eyes, the appeal is very quickly lost if you don’t know how to handle them. Clarity and appeal are the keywords when working on eyes so the first rule of cartoony eyes posing is :

1. Centering:
Never, ever, have both eyes (pupils) centered on their respective orbital cavity. Instead and to avoid the zombie look, get the pupils closer to each others and have more space/white (sclera) on the outside of the eyes. This will create a more appealing pose.

2. Favouring:
When a character is looking sideway, one eyes should be centered and the other one much closer to the bridge of nose or even intersect with the orbital cavity:

3. Focus:
As the character focuses on an object really close, you might want to increase the space on the outside of the eyes but when the character is looking far away, again, do not center the eyes! (see rule 1)

Presto_02

4. Surprise
Even when trying to communicate surprise, we still revert to rule #1 and have more space on the outside of the eyes.

5. Sideway
If your character is totally sideway, cheat as much as you can just so we can still see a sliver of the Iris

Bonus tip:
Pay attention to the way the top lid is shaped on half lidded character in Zootopia, especially Nick. This will be included in a forthcoming article about stylised animation.

Impressive fan made Elsa rig

Posted on July 14, 2016 
Filed Under Animation, Education, Modeling, Rigging | 1 Comment

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!

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

Posted on January 3, 2016

[addons]
2018.10.01. v02.01 section 17 added relative to colourblindness

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.

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

IK/FK switch buttons with no pop

 

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.

 

17. Controllers colours and colour blindness. 1 in 10 men and 1 in 200 women are affected by colour blindness. For most, green is a difficult colour to see so refrain from using the red/green or green/yellow combination. Instead you should favour colours that are widely contrasting like red and blue for example. I know it looks pretty ugly in term of colour harmony but rigs primary goal is to be efficient, not pretty. If you don’t know if you are colour blind, test your sight here, personally I am moderate colourblind and can’t see half of the plates http://www.color-blindness.com/ishihara-38-plates-cvd-test/#prettyPhoto.

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:

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…..

I had to dust off this blog to post those really cool character studies for Disney’s latest movie Big Hero 6. Other than that I eventually moved back to London and am currently working on Okido, a fun kids TV show which I will feature very soon. London’s grass is so much greener! ;-)

Character walking into a room, what a better way to depict a character’s personality especially when done by Disney animators.

Premo, the Dreamworks animation software

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!

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.

Frank and Ollie Documentary

Filed Under Animation, Education | 1 Comment

If you still haven’t bought “the Illusion of Life” or the “Frank and Ollie” DVD I don’t think you can really call yourself an animator!

Frank and Ollie DVD

There is nothing I can do for you regarding the Bible of Animation but if you were put off by the “Frank and Ollie” DVD’s NTSC only format you are in luck, Youtube user Paul Stanton posted a more or less legal copy of that fantastic and hearwarming documentary on Disney’s legendary animators Frank Thomas and Ollie Johnston.

If you are too cheap to buy the DVD, I highly recommend you to watch it before Disney’s legal department finds out.

http://www.youtube.com/watch?v=5m7z1XUgdQ4

I will take this opportunity to mention the AWN hosted Frank and Ollie website, a website whose content was created by Frank and Ollie themselves in (cough) glorious Comic sans. The website contains a great amount of animation notes you need to keep reminding yourselves.

And to finish, here is a quick introduction to the work of Frank and Ollie by Disney’s animator extraordinaire Glen Keane
