Mohair - Photometric Stereo based PBR Material
Photometric stereo based scan of mohair fabric. This time I used a flash light as a source of light. Material was generated with Details Capture from 37 images. More info about the technique used for this capture is available on my youtube channel in this video:

Seams were removed 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 for my incoming video about color calibration and would be a waste not to share. Not sure is this a genuine mohair or a sythetic one tho :)

PBR preview: Albedo / Normal / Height / Roughness / Ambient Occlusion
Setup with slim light I used to capture this material - more info in my video:

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 treated with ultraviolet 365nm wave length light to trigger light re-emmission in visible wavelength range.
Source material - 1mm field of view
Details Capture - photometric stereo reconstruction based on 37 images.
Unity ArtEngine - probably the best tool available for automated seams removal from scan based materials. I also used it to generate roughness and ambient occlusion maps.
