Effects Technical Director, Animator, Artist
I worked in the US Film Industry after graduate school from 1996 to 2013. For the first 8 years I was lighting and compositing. From 2004 to 2013 I specialized in effects animation, a generalist role that handles the visual elements that don't fit in the standard animation pipeline. The role was called Technical Director, Animator or Artist in different places and the people I worked with spanned a wide spectrum of artistic talent and technical know-how that defies easy categorization.
- Effects TD
Tools - As an effects animator I primarily worked with SideFX Houdini. It's a node based visual programming package used to animate physically based simulations of fire, water, destruction and other natural and manmade phenomena. The simulations generate volume data, geometry, or particles that are lit then rendered into 2D frames. The frames are composited with plate photography and other CGI elements into a seamless whole with Nuke, a node based analogue to Photoshop.
Simulations vs Keyframes - Unlike keyframe based animation, simulations are scaled down version of a physical event where I would set parameters of forces, materials, boundaries and other conditions that could affect the simulation. Once the parameters are set the simulation has to run sequentially from the starting point through the most of the shot length before we could see the entire results.
Art Directed - We are simulating natural phenomena that would be too dangerous, difficult, or expensive to film in real life. Or it maybe it's at a scale that's never been seen before. The key to success was not straying too far from the natural results of the physics based simulation while meeting the needs of art direction that's focused on telling the story from the camera point of view.
Teamwork - On film projects I collaborated in person or remotely with 200+ member crews of other artists, production, and creative leadership.
Iterative - On a daily basis, my work was looked at in isolation and in the context of other elements until each shot was complete. If the direction changed I was responsible for saving and logging my work so that any iteration could be recreated with the asset management tools to match a previous iteration.
Technical - Simulations are computationally intensive ie take up lots of computer resources. As artists we were conscious about being economical with our resources so we could get feedback on our work in a reasonable amount of time. We worked in a command line environment that allowed us to chain processes with scripting languages like c-shell, perl and python.
Leading Edge - These effects were pushing the envelope when they were done. A Hollywood effects film is big investment that's intended to wow an audience with spectacle and story. It is a unique environment to work on something that only exists in the Director's mind's eye and needs to be spectacular in 18 months after you've first start working on it.
Deadline Oriented - Movie release dates rarely change. All the work shown is done on a tight schedule with resources re-allocated as needed to meet the deadline. The work is done to a very high standard with a lot of effort.
An effects demo reel is usually sent along with a cv and a hard copy breakdown of the work.
In an interview the artist and potential supervisors will play through the video and discuss work that might be pertinent to the upcoming movie.
It's pretty straightforward and devoid of the overt salesmanship of a design pitch meeting. We review at a lot video on the job. The need for the work is already established and the scope is not the artist's purview. Execution at a high standard is a given and we want to focus on almost subliminal details that most people barely notice.
