3Delight Specular model ... anyone?

evilded777

So... in shader mixer we have a 3Delight option in the Specular brick as distinct from a blinn or phong.

In pwSurface2 we also have an option to use this 3Delight specular.

Anyone know what it is? BRDF? Something else? I know there's another acronym that BS-something.

What does it incorporate? Fresnel, one hopes?

Just doing my research.

Thanks!
