Whilst it’s true that a thin-film is always perfectly specular, the final look can become rough as it follows the shape of underlying surface microstructure. Most of the time the presence of a thin-film is very subtle, but it is essential for achieving a highly realistic look.Ĭoating doesn’t have a roughness setting and so logically you might think it makes no sense using it on glossy/rough surfaces unless you need a polished look. Up until now, we haven’t seen much usage of the Coating component other than making soap bubbles or simulating the coloration of shiny ornaments.Ĭoating plays a key role in photorealism for simulating everyday materials such as leather, plastics and more. This post is about thin-film layers, and how you can use them to create extreme realism with your materials.Īs you may already know, Maxwell Render is capable of simulating Thin-film Interference using the Coating component in the material composition.
