Cloth shading is a topic I have revisited over time. In January 2015 I have decided to release it to the Unity community as a Shader Forge graph at the asset store. I would be happy to see it used in your games. As you may see in the screens and video, you will be able to emulate key lighting behaviours of a wide range of fabric surfaces, from rough fabric such as towel or carpet, to silk or velvet.
In 2014 I made two demos for Unity Technologies, both shown at Unite 2014. First one was a car rendering project, for which I have developed a layered shader to model car paint features. It consists of a metallic base, lacquer layer and one more layer on top for dirtiness.
I made this environment and material switcher app to test the shader under many different lighting situations.
Then I was asked to polish my skin rendering system for ADN. This project was also supported by Unity. I spent one month working on it at home. Once it was ready to rock, I went to Paris to meet ADN guys and get the demo done. It was an unforgettable and pleasant experience.
After some years using Lee’s scan, I had the feeling that it was time to switch to another model. It wasn’t easy to find a good one so I decided to start zBrush and see what happened. I’d never tried to model a face before so it was a long process. And finally, Dave was born.
