We have enhanced Thea material system with thin film interference support as an extension of Glass material with the most accurate solution of the phenomenon. Interference is a phenomenon actually very common in life but rarely solved by render engines. It can be seen very easily on bubbles and CDs (the film thickness being on the visible light wavelength order) and it is wavelength dependent resulting in beautiful color variations.

The new material (ThinFilm) not only can stand alone (for example, modeling a bubble) but also can be used as a very thin coating type (for example, an oily layer on a metallic surface). Bump mapping is also possible now.
