Supervision
» VFX Supervisor: Overall in charge of the look and implementation of
the shots. Will be on set to make sure that things are shot correctly.
Will be the one to talk to the clients about what is needed. On bigger
films, there is often a client VFX Sup, who works on the entire film
and oversees the whole thing, and a VFX studio VFX Sup who will
actually work with the artists. (The client VFX Sup only really deals
with the director and the VFX studio VFX Sups)
» CG Supervisor: Responsible for the 3D side of things - all of the 3D
artists, and making sure that the compositors get what they need to
make the shots work.
» 2D Supervisor: Looks after all of the compositors, and the 2D only
shots, as well as the integration of the CG into the shots.

3D Artists
» PreViz: This is a pre-production job rather than a post production job.
Creates relatively rough animation so that the director can make
decisions on camera angles before he gets onto set. Often used for
situations where there’s going to be a lot of VFX, it also gives the
actors an idea of what the shot is going to look like, even if they’re
just working on a greenscreen set.
» Matchmove: Tracks the live action camera move in 3D, giving a 3D
camera that the CG scene will be viewed from.
» Modeller: Creates 3D models of objects/characters

3D Artists
» Texture Painter: Creates the 2D images which will be layed over the
3D models to give them colour and texture. There are usually many
textures for each part of an object, defining things like the basic
colour, the displacement, areas where there’s more specular
reflection, etc. Not necessarily a 3D job, but it’s more tied in with the
3D side of things than the 2D side, so I’ve included it in the 3D
section.
» Rigger: Creates the rig (skeleton) to go inside the model so that it is
easier to move bits of it without having to edit it veryex by vertex.
» Animator: Takes the rigged model and gives it movement.

» Technical Director (TD): A number of the more technical of the 3D
jobs are classed as TDs. This is nothing to do with directing in the
usual movie sense of the word.

3D Artists
» Effects TD: Often particles - dust, snow, rain, etc. Also cloth and fluids.
Bigger companies may have people who specialise in cloth, or fluids,
etc.
» Lighting TD: Adds lights to the scene. This is the final artist in the 3D
pipeline. Often will deal with rendering too. Or the rendering will be
done by a…
» Render TD: Makes sure that the scenes that the lighter finishes with
will render properly. This may involve optimising the scene to make
sure that it will render as quickly as possible (for example, deleting all
of the geometry that won’t be seen by the camera)

2D Artists
» Roto Artist: Cuts out objects, often frame by frame (although
interpolation is allowed). Often used for situations where a
green/bluescreen was not feasable for cost/time/intelligence reasons.
The roto artist may also be called upon to do rig and tracking marker
removals, and other clean-up work.
» Matte Painter: Creates 2D background paintings that are usually used
by the compositors, but may also be passed back to 3D to be
rendered in multiple layers
» Compositor: Takes the rendered CG, and the live action plate, and
any other 2D elements and puts them all together, producing
(hopefully!) a result that looks as though it was all shot at the same
time.

R&D
» Shader Writer: Writes shaders, which tell light how to interract with the
different parts of the model, and how to use the textures that the
texture painter has created.
» Pipeline Programmer: Writes the pipeline software. This is software
that doesn’t actually create images that will appear on the screen, but
that helps the artists workflow, and overall improves efficiency.
» General R&D: Writing anything else that the artists may need.
Anything from plugins for Shake or Maya through to crowd generation
tools.
