Nimja Hypnosis CopperA test render with some light.

This render was made using Blender for modelling and LuxRender as the renderer. Both are free and open-source!

What makes this special is that LuxRender uses physically based correct rendering methods that will cast really nice reflections of light, even when something is just copper. The setup is just a room with a "window" with sunlight falling in naturally. No other lights needed, as all other light just bounces inside the room.
