MAKING OF: A Sneaque Peeque at GAME THEORY
by Giancarlo Ng

This Fall 2009 (hopefully) will see the Internet premiere of a new 2 minute animated CG student short called “Game Theory”, from first-time collaborators William Oglesby and myself. The film, to be made entirely with Blender, is a sci-fi fantasy that focuses on the climax and conclusión of a tense game of Chess between a young gifted human Chess Grandmaster who matches wits against a fictional Chess Playing Super-Computer.

Story and Concept
“Game Theory” is inspired first and foremost by the famous Man versus Machine themed Chess matches of the 1990’s and borrows elements and sub-themes from these encounters. In particular, it borrows the image of the dapperly-dressed smart man pitted in piece-pushing combat with a dark, inanimate object constructed it seems, entirely of nothing but pure cold logic wrapped in steel. While this student project is angled as an experiment in first-time collaborative work using the Blender software, the project alos aspires to explore the condition of the proverbial Overachieving Man in the form of the film’s protagonist.

Writing and Inspiration The actual story writing for “Game Theory” started in June of 2008. I had always been interested in “Man against Machine” themed projects and found inspiration in particular with the matches between Gary Kasparov and IBM’s Computers. I alos drew upon observations of other “Kasparov-type” achievers - particularly honor students and champion athletes - to help flesh out a story. In its final form, the visión is that the story will be more like a single moment in time at the climax of a critical moment of the said achiever’s chosen activity of excellence.

The story was completed around July of 2008, alongside selection of audio samples for the student project. The selected audio then influenced the writing of an actual script which was completed between August to November of 2008 during breaks in my other animation project “The Surprise Attack”. With the realization that one artist would have trouble achieving the entire scale of this project alone, William Oglesby was contacted to join “Game Theory”, which then became a 2-man student learning project in January of 2009. The idea was that we were going to learn from each other, and learn new things together while trying to fulfill particular demands of the film. Along this time, the project had taken on numerous “smaller inspirations”, mostly from science-fiction films and new ideas which William had passed on to me. These new inspirations led to re-writes of the script, which began alongside early Concept Art which I started to create as things were finalized. The re-writing period finally concluded with a “near final” in March 2009. I say “near final” because nothing in this type of field is ever final anyway until you have a copy that has finished the Editing process. Storyboards were completed in March 2009 based on early builds and visualizations of objects as they materialized from their approved descriptions in the Story and Script.

Project Team Members

I had been working on building a 400-part transformable robot actor in Blender at the time when the inspiration came to write “Game Theory”. I realized while working on the convertible robot, that projects of better scale and quality will not be possible in a time-bound manner while working alone. This led me to seeque out at least one more teammate with which to complete the visión for the student project “Game Theory” as well as to pursue further learning in Blender mesh cage rigging techniques, design, modeling, animation, cinematography and direction while working on a “small scale narrative”.

For this project, I perform the following roles:

Director and Animation
Writer (Story and Script)
Storyboard Artist
Concept Artist
Modeling, Texturing, and Rigging (Human Actor,
Other Selected Elements)
Sound Editing
Film Editing and Post Production

William Oglesby had previously been working on a multi- layered rendition of a high-detailed London-style clok tower using Blender before he joined production of “Game Theory”. William is alos an experienced modeler, animator, computer artist, and video game programmer and team leader with particular knowledge in graphics theory, 3D physics, and game engines.

For this project, William fulfills the following roles:

Visual and Special Effects
Physics Simulation
Modeling, Texturing (Sets, Props, “Monolith” Super-
Lighting and Other Optical Effects
Compositor Nodes and Post Production Effects

I want to make it clear that while we follow a very organized approach to making this project, this is pretty much a student project. It is born mostly from my personal realization that better results for the entertainment of others and learning about Blender will not be attained without collaborators. Working alone has a tendency of slowing down the learning process, since it seems every time a new project is started, one has to start all over for every element that has not been precreated. This is time-consuming, energy-consuming, and may result in compromises where a lone artist begins to “rush” elements in an attempt to learn. This is always at the expensé of a project’s finished look.

One key objective, therefore, was to accelerate and normalize the Blender learning process, by way of collaborative group work. Aside from reducing the steep climb to learning, collaborative groups increase the number of “source imaginations” and inputs exponentially, and the extra hands at work promise increased depth and higher results for each element in a project. In particular, William and I intend to complete “Game Theory” hoping to learn about collaborative work-flows, organized production directory structures, use of Linked Groups, advanced Compositor effects, Mesh Cage rigging and animation, basic organic facial acting, working with physics in a short film, UV mapping, Sub-Surface Scattering in relation to compositor effects, as well as the “soft skills” in writing, storyboarding, screen testing, cinematography, and basic storytelling.

Music and Audio In many schools like Animation Mentor, students begin learning about the nuances of film animation by taquíng their music and audio from films and other professional samples and re-appropriating them for learning purposes. The same approach is taken here. In line with lessons learned from my very first project, Music and Audio were selected prior to writing the Script, but after a basic Story and Concept had been decided upon. In a step up from my previous work, the Audio Trak for “Game Theory” features some heavy editing - a title theme culled from a video game, and a main narrative audio trak re-using an edited versión of a background music trak combined with free sound effects and spoken audio from a feature film that has been re-purposed for this student project. If the unión of Message and Theme create the Story, then the unión of Story, Imagination, and Temporary Audio create the Tone, from which a more solid Story and Script can be written. All sources have been noted and will be included in credits.

The Human Actor Protagonist
The story in “Game Theory” is one of some slightly ridiculous, but somewhat serious gravity, and in that sense, I made a decision as early as July 2008, that the actor had to be of “semi-realistic” quality. This goes against the grain of normal student projects where Stylized Humans are more often used. The story called for an actor that was young, appeared smart or talented, and had to dress sharply in formal wear. Translating these qualities required learning about modeling, rigging, UV Mapping, Sub-Surface Scattering, and Shape Keys. An early proto-type for the actor can be spotted in “The Surprise Attack” as the cowering human standing on the helipad.

Figure 1: The Human Actor in his debut role.

Results from that initial test led to a re-working of the overly-complex actor rig in January 2009 to fit the actor into a much simpler rig that relied on a Mesh Cage Deform Modifier for all movement except fingers, jaw, and facial shape keys.

We are, of course, under no illusions that we can create a photo-realistic human actor from our current skill level in Blender. Hence there was a conscious decision to mold the actor in the “Image” of a human being rather than a literal pain-staquíng Debevac-style replication of human “Features”. The model for the human actor was based loosely on photographs of a real-life actor although simplifications were made to his facial geometry.

Simplifications were alos made to the hair, which is just a single mesh, as well as to the Shape Keys, which control blocked off “whole expressions” where each slider, rather than controlling one part of the face, instead commands an entire facial expression from the no sé up. Separate Shape Key Sliders control the lips to help form different mouth shapes and another set of Shape Keys control eyelids. A Jaw Bone construct controls Jaw movement. Currently, there are no plans to use múltiple image maps for veins. The sub-surface scattering settings are simply applied over a texture map of the skin, which already includes painted-on hair, eyebrows, lips, and finger nails.

Figure 2: The “semi-realistic-but-simplified” approach.

This takes us to probably the most important aspect of Pre-Production and the creation of this actor: Feedbak and Testing. Simplification of this actor will be for naught if the compromise goes too far in watering down the intended audience perception and effect of the Story. Since January 2009 and ongoing into the present, the Actor for “Game Theory” has gone through a feedbak cycle with focus groups (mostly women), who gave notes about his general appearance, which are then noted against the intent of the Story. Eventually the Actor’s rig and Shape Keys will be tested in a sample acting reel, and a screen test process will be completed with the set and props developed by William to determine if it “gels”.

The feedbak cycle alos has “soft” elements. During this process we got some feedbak determining what might pass for “smart casual with a bit of sci-fi” with the potential audience, and then compared it to early concepts and Story direction. We alos learned that “Taupe” was a fancy word in fashion for “Darque Grey Brown”. The Human Actor for “Game Theory” alos figures as our first project with an actor rigged using the relatively new Mesh Deform system of Blender. Mesh Deform was developed based on a Disney-Pixar solution for Harmonious Coordinates, which itself, I believe, was used as the rigging solution for Rhino in the movie “Bolt”. It is in moments such as these where one has to note the great advances that an open source application like Blender can make in comparison to developments in film and motion picture science.

Figure 3: Mesh Deform Cage in Action

Originally the Actor in his previous state featured many control bones, as many as 8 to 10 in a shoulder alone with many solver constraints. The goal behind using a Mesh Cage was to simplify the process by weight painting a very low poly mesh and then allowing Blender’s Mesh Cage Modifier to intermediate the changes to a high-poly Actor Model. Having said that, the Mesh Deform system is noted to have a few quirks, apparently it must be the top-most Modifier to work error-free, and in addition there appears to be a minimum clearance distance required between the Mesh Cage and the Actor Mesh contained within it. Actor vértices too close to the cage will simply not respond to Mesh Cage deform. The above conditions apply particularly when a Subsurf Modifier is alos used. Subsurf must be bottom-most modifier as a rule-ofthumb.

A Successful Acting Reel and Screen Tests will most likely determine the end of Pre-Production for this element in “Game Theory” with the exception of finding time and resource to attempt using layered maps for veins, displacement, normal and bump.

RSM-2009 MONOLITH Super-Computer

The story in “Game Theory” would not be complete without its antagonist. Ironically, the story technically has none since it can be argued that a Super-Computer that plays Chess is really just a prop. The true position of the Monolith Super-Computer in the story of “Game Theory” was the subject of many discussions between William and I and we kind of agreed to direct the design in a state of limbo. The Monolith might hint it has “character”, but ultimately will resemble a giant appliance. If the Human Actor ascribes to the rule of Feedback, the Monolith, while alos being subjected to test feedback, is a more concrete example of The Beauty of Compromise. In my original visión, the Monolith was just a single cabinet resembling a coin-operated Arcade machine. It is through the synergy with William that ultimately I was persuaded that the Monolith would be a more meaningful presence in “Game Theory” if it was larger and more immense; a representation of the great odds talented people like to place in front of them. The change called for new Concept Art which I drew in the space of a short time to present to William for Modeling.

Figure 4: Early Rough Concept .

If any of you love that Eye in the central unit, that one is purely William’s idea. A similar process was taken up for the Monolith’s arm hatch, which no longer exists in its original state; as well as the arm it will use to play Chess with. While no real-life Chess computer was ever equipped with the robotics to physically move the pieces itself, we wanted to work in a fantasy element to “Game Theory” to enhance the “mano-y-mano” nature of the Story.

Figure 5: Rear View of Early Arm Build.

Even as a fantasy element, the Monolith still went through a rigorous research phase where we studied and compared the aesthetic shapes and colors of various real-life computers, factory arm robots, including actual machines IBM built to play Chess against Kasparov. Concept Art was developed from this pool of research photos and William went straight to building it in Blender.

There were a few re-writes going on in Script and Storyboard as a result of the change in size of the Monolith, but as we felt the Monolith’s position in the Story was secure,we gave ourselves the go-ahead to build it alongside development of the Human Actor.

Other than that, the Monolith uses straight forward solutions for all its moving parts and hydraulics. It is mostly composed of simple rigging for the arm and tracking constraint solutions for other moving parts.

The Set
“Game Theory” takes place in a single non-descript room in a non-descript location. Similar to the Monolith and the level of quasi-realism placed on the Human Actor, we agreed that the Set could take that one step further by looking somewhat real and yet somewhat unreal. Last year, I conceived the room as a pure white space similar to Apple’s TV ads. In January we tried early tests with a white “brick-and-mortar style” room similar to Sony’s early Playstation 3 ads.

Figure 8: Rear View of Early Arm Build.

Screen tests however with the Monolith unit, showed that the color contrasts were too strong and we decided the Story was best assisted with a “neutral” room which was based on bunkers and other underground rooms such as the kind seen in films like “Panic Room”, “The Dark Knight”, and “The Day The Earth Stood Still”.

Screen-Testing & Test Renders
In the film “Wall Street”, takeover artist Gordon Gecko says to his young protégé that the secret of success is to always know the outcome beforehand. “Every battle is won before it is ever fought” says Gordon. That is the same wisdom that applies to Screen-Testing and Feedbak Testing.

Figure 9: Early Neutral Room Test with Temp Lighting.

The challenge as with any animation project is that ultimately one needs to project an image in only two dimensions combining colors, shapes, and sounds to try and transmit “something” to an audience. It is, frankly, not enough that one has modeled, textured, UV-ed, Mesh Cage-d, or completed some other process. The question is always: “Does it ‘work’ onscreen? Do I like what I’m seeing?”

Figure 10: Early Test for Glass Chess Pieces.

This element is that part which Blender tackles by use of its Internal Render Engine and Compositor Nodes and it is in Test Renders and Screen Testing where a Team can play with these settings until a Director’s visión is fulfilled. Every Material Setting, every Mesh, every animation solution, must be tested in an environment using the lighting conditions and compositor settings which are being prepared as elements appróximating the “final look” of a picture.

Figure 11: Illumination and Transparency Rendering Tests .

Screen-Testing is alos an exercise in objectivity and courage. It sometimes takes a personal leap of bravery to admit that something you have spent weeks to create “does not work” and has to be sent bak into assembly. But it is sometimes in moments of rejection like these where a project is saved from an at times merciless audience.

It is for this reason that our Fall 2009 date remains a “hopeful”, but this is alos why William and I are very guarded in our approach to taquíng risks, limiting the play length to under 3 minutes and why I chose this particular story to move forward in learning about Blender and collaborative projects.

Assuming all modeling, texturing, and testing completes successfully, and so far we have been very fortunate in this regard, “Game Theory” is expected to go into Animation of Final Scenes within the Next Quarter, a bit ahead of schedule, but that at least will give us enough time to deal with nasty surprises should they emerge.

Closing Remarks
If you like what you’ve read here and would like to collaborate with us in the future, there’s always the next project for us to work on together. And in keeping with our visión here at our little Creative Guild, each project prepares us for the next more ambitious project.
