ArtisanWeavedCotton - Photometric Stereo based PBR Material
Another photometric stereo scan turned into PBR fabric. This time it is a fabric made of Cotton 40%, Polyester 20%, Linen 16%, Viscose 12%, Wool 8% and 4% of Polyamide. More info about the technique used for this capture is available on my youtube channel in this video: https://youtu.be/7YGd3bcO_Ys
Material was generated with Details Capture and tiled with Unity ArtEngine. Images used for reconstruction were initially preprocessed with the PhotoLab5.
I included some macro shots as they help to understand light response from the surface .. and because I captured them anyway for my incoming video about color calibration and would be a waste not to share :)
Cheers!

Setup with slim light I used to capture this material
Source sample with the 4cm ruler used as a scale reference and 5mm chrome sphere for light direction auto detection
Source material - 10cm field of view
Source material - 5mm field of view
Source material - 5mm field of view seen in invisible for human eye light spectrum (ultraviolet 365nm). Since this one isnt as synthetic as a previous one, I expected it to be much more UV reactive, but apparently none of its components are not :)
Source material - 1mm field of view
Details Capture - photometric stereo reconstruction based on 24 images. Unity ArtEngine is also an option to consider but it is limited just to 16 input images while Details Capture has no such limit (afaik its max 256 if there is enough RAM).
Unity ArtEngine - probably the best tool available to automaticaly remove seams from most of scan based materials.
