Modus FX Journeys into the Far Nor with Sarila

Montreal Facility Creating Canadas First Stereoscopic Animated Feature

Modus FX has embarked on an ambitious new stereoscopic 3D journey an 80-minute animated film called Sarila. Directed by Nancy Florence Savard, Sarila is a compelling coming-of-age story set amongst the Inuit people of the Arctic. Starring Christopher Plummer (The Sound of Music, The Last Station), Genevive Bujold (Anne of the Thousand Days, The Trotsky), Rachelle Lefevre (Twilight, Barney's Version), Dustin Milligan (Beverly Hills 90210, Slither) and Natar Ungalaq (The Fast Runner) the production will be the first feature-length stereoscopic animated film created in Canada.

For director Savard, the film has been a labour of love for the past ten years. Sarila tells the story of three young Inuit who strike out on their own in order to save their clan from starvation, she said. This is an inspirational story, full of hope. It shows young people facing daunting challenges and, through the experience, taking control of their lives. Their world is exotic to us but their experience is universal.

Written by acclaimed childrens author Roger Harvey and Pierre Tremblay, an expert in Inuit culture, and adapted by Paul Risacher, the film uses authentic settings and indigenous mythology in order to capture the world of the Great White North.

The story draws on Inuit legends from different regions of the arctic, said Savard, but then it moves beyond those traditional archetypes to tell a new story.

Sarila invites the use of stereo 3D, explained Savard. The characters travel across the tundra, through snow storms, and meet strange, semi-mythical characters along the way. The immersive quality of the stereo 3D draws the audience into their odyssey.

Modus FX came on board as a investment partner late last year, and began working with the film's art director Philippe Arsenault Bussires in January to translate his water color concept art into 3D geometry that can be rendered stereoscopically. The result is an original, stylized aesthetic for stereo 3D.

In our VFX work we usually mimic reality, but with this project we are creating something different, said visual effects supervisor Eric Clment. Our goal is to capture the essence of the original concept art. We want to push the look of stereo 3D, instead of going in the photoreal direction that a lot of current animation is doing.

Working together with the art director, the texture team at Modus developed a technique for mixing colors with a custom brush in Photoshop. Surfaces, such as the characters clothing, for example, blend a watercolor look with photographic references to create the final result.

Modus currently has a team of 85 artists on the project, many of whom were involved in the facilitys recent March of the Dinosaurs project, a 90-minute animation for National Geographic and The History Channel, which was, coincidentally, also set in the Arctic. Sarila includes 950 shots, so the 15-month production schedule requires an efficient pipeline and relies on several key Modus-developed technologies.

Setting the Scene in the Arctic

The vast and desolate landscapes of the Arctic play an important role in the narrative and atmosphere of the story. Since the film is in stereo 3D, the process of creating these landscapes is more complex than with traditional matte painting. The old-school tricks of doing 2D cheats' in compositing, like doing a matte painting to extend the background those don't work in stereo, said Clment. You need to include the geometry with the images.

To solve the problem, the Modus team has developed a pipeline for creating 3D maps of matte paintings. The spatial coordinates for each landscape are built in Softimage XSI, allowing the team to create and render left and right eye cameras. The shots are then assembled in Nuke, again using custom tools developed at Modus. This way of building our 3D geometry is very effective for working out backgrounds, such as skies, explained Clment.

Another challenge for stereo 3D animations is the volume of data to be managed. Modus has developed a number of technologies for this, including the Modus FX SceneBuilder. This tool enables artists to load subsets of a scene, in order to work on one particular element without the overhead of the whole scene. The film includes 30 different environments, so the MFX SceneBuilder has become a critical tool in keeping our shot pipeline moving efficiently, noted Clment.

Modus has also turbocharged their infrastructure by implementing the new Arnold rendering system. It's amazingly fast in terms of motion blur, subsurfaces and other computationally-intensive processes, said Clment. This required creating a new compatible shader library, but the faster render times have easily justified the extra effort. We keep finding ways to get more out of our pipeline, he added the result is that our artists can focus on the art, and dont have to think about the technology.

Rigging Done Right

Sarila has a total of 35 talking characters, including people and animals, so rigging and lip-synching are another area where an efficient workflow is critical. We have bipeds, quadrupeds and birds to animate, said Clment, so we created a system that would allow our artists to rig their characters in different shots without having to start from scratch each time they started on a new scene.

The Modus FX AutoRigger, developed specially for Sarila, allows artists to generate biped and quadruped bones structures. With the MFX AutoRigger artists can apply movement patterns to their characters automatically and then manually adjust the movements for each shot. For example, for a sled pulled by five dogs, we want our animator to be able to start with the basic running movements and refine the work from there, explained Clment.
