The new PBR system has something that changes my mind... maybe the sunshine from Montpellier :D

So I did some experiments with different types of materials and I combined the specular ones with my other concepts and this is the result.

I tend to catch the huge amount of the sunlight, so I disabled the clamping (raised the limit to high) and I used special filtering/fringe/glow combos to avoid flat results. The factory preset for gold is quite good:

Hi,

here is an untouched photogrammetry model with different times of a day.

I "unlit" the phototexture in Clarisse to get the proper diffuse color input.
It has just a diffuse shader now (maybe too rough), the glass will have different, and other lighting effects will come.

Hi!

I created an asset which can "simulate" finger smearing, this is a greasy one:

In the system that creates the vector texture for the anisotropy effect, I used "B mode" for long exposure, explained here:

http://forum.isotropix.com/viewtopic.php?f=5&t=1746

Firstly I animated a dummy fingertip (sphere with procediral clip map for the scratches) and baked into the poly plane with this long expo mode using utility node as input with Motion Vector setting (Mblur+Mvector was set accordingly @ path tracer).

it has black part because these are negative values
