Requirements for a specialist depend on the chosen direction, for example, a modeller needs to be well versed in coloristics and textures, the visualizer – to understand the technical documentation, and the animator needs to know the anatomy of movement.

So we list the general knowledge and skills that should be in any 3D-designer:

Basics of design, working with color and light, texturing.
Different artistic styles.
3D graphics.
Modeling features in games and movies.
Animating objects and characters.
Rendering.

And also a specialist must be able to work in graphics editors. The basic 3D-engineer stack:

Autodesk Maya and 3ds Max for animation, modeling and rendering.
Photoshop for retouching and color correction.
ZBrush for 3D sculpting.
Blender for sculpting, animation, simulation, rendering, post-processing, and video editing with sound.
Houdini for creating special effects.

Place of work
Specialists in three-dimensional design are in demand in various industries. Let’s list the main areas in which 3D designers work:
