This project was done as a 3D environment art study for personal development. I had begun the project in Unreal Development Kit, however shortly after I moved it into the CryEngine 3 Game Development Engine, for concerns that UDK was not high enough quality for what I had envisioned. CryEngine offered me much more flexibility with textures and lighting, and a higher graphical fidelity in general.
The entire environment was crafted over the span of 1 year from scratch, but was done in about 100 hours of actual work time. That includes multiple concepts of the environment itself, learning a new game engine, creating the 3D models in Maya, sculpting the high-poly models in zBrush, painting the textures in Mudbox & Photoshop, lighting the scene in-engine, coordinating sound effects and particle dynamics, and setting up cameras to film within the engine.
