Below is a collection of screenshots taken from a couple levels from a canceled sci-fi game project using the Unreal engine. I generated several of the assets including models, textures, and material shaders, and I had a hand in assembling the level.
Below are some 3ds max wireframes and texture sheets (Diffuse, Normal, and an RGB mask for Specularity/Reflection, Gloss, and Glow) for those of you who like that sort of thing. Everything is displayed on a 64unit grid.
The below level was created from assets generated primarily by other artists on the team. I arranged the modular pieces in the Unreal Development Kit and lit the level to create an interesting gameplay area.
