As the author of the original 'Cycles BMW Benchmark', I thought it would be interesting to see the same car running in the game engine. So I spent a weekend redoing the scene, materials, lighting, and geometry to make it more game-friendly. The result is this:
- Videotexture for the realtime reflection
- Easymaterial Uber material for the ground material
- Lots of textures layers including liberal use of stencil (No nodes)
- 2D filters for color enhancement and vignette
