I am half way though making some "clutter" for a bedroom scene and thought this one was worth sharing.
The disc refracts light fairly accurately.. It is a similar method to RGB refraction as seen in the Sony Nex7 by ETA. All parameters including coating colour are adjustable. The disc is to scale and fairly high poly for it size.
Sorry guys, all images have been removed from the blend
Let me know what you think =]
