This is my first post on IdeaStation and was advised by @colin.smith Community Manager.
In this thread I was asking about multicolor iridescent material (basically based on angle falloff map). Such materials are used commonly in car-paint shaders but I am rather interested in coated lens like material (used e.g. in modern sunglasses).
Anyway it could be a simple two color angle based shader with adjustable transparency and reflectance. I believe It would help a lot in visualization coated lenses and other iridescent stuff.
I hope you like it and vote for having it built-in in next versions of Fusion 360!
