Title: Films and coatings
Post by: nfree on December 12, 2013, 06:24:35 pm
I'm looking for white or light gray gloss material with a soap bubble like color expression in the gloss coat. It seems like the DuPont paint materials may have some of this going on, but I can't figure out how to do it. Trying to get a similar look to this...

Any help would be great!!

Right now the easiest way to achieve this is to model both surfaces (the thin film coating) and the underlying diffuse material. We are going to add layered materials soon, which would be another approach. The DuPont / Axalta paint does not have interference (the source of soap bubble colors).

This is good news. 

I hope it works with metals because I frequently render anodized titanium (a process that creates colors based on interference, much like an oil spot on your driveway during the rain, or the colors in a soap bubble). 

In a photo of an anodized titanium round bar for example, you can see a slight color shift on the portions of the surfaced that are off axis from your line of sight.

Things to think about

colour spectrum

Thickness of film to be mappable maybe?
