A bit over a year and a half ago I was applying for an environment artist position at Gameloft in Auckland, New Zealand. As every other applicant, I had to do an art test. The requirements were to create a night port scene environment with 2 cranes, a cargo ship and a warehouse in under 3600 triangles.
The focus for my piece was to create a really low-fi art style, with pixel art textures.
What I ended up with was everything textured in a single 512 bitmap (excluding the skybox).
I am still currently employed at Gameloft as a 3D artist with emphasis on technical side of things.
