Below are some examples using some bokeh images from www.dofpro.com
Apparently some (rather naughty) people went in and scanned the contested Egyptian Queen Nefertiti bust at the Nues Museum in Berlin without their permission.
I guess you could say they stole it just by ‘looking’ at it. Hehehehe………sorry.
The high resolution model (around two million polygons) is freely available to download here (.obj).
How to achieve a specular speckle effect (see video below)? This effect is visible in various places such as car paints, plastic coatings on mobile phones, christmas ornaments, snow etc.
“GGX is a microfacet distribution. It has a sharper peak and a larger tail than Beckmann. GGX is suitable for modeling light reflection from surfaces more realistically.”
It seems to give a subtle softer highlight that falls off more gradually. The effect seems more obvious on the brighter specular highlights on the metallic surfaces below.
The Standard shader has a new Diffusion Profile called Empirical (the default is Cubic). Empirical is a more physically accurate subsurface scattering profile, that, with a single layer, can capture both surface detail and deep scattering.
