Wood - Photogrammetry based Environment Material

Any environmental PBR material library wouldnt be complete without any generic material of wood we can use to wrap wooden elements.
Initially I captured this one testing shooting with bare hands with the heavy flash mount as part of my research for this video: https://youtu.be/c7tI6ICo23I
It was scanned with hand held camera with the flash from quite close distance but without any filters mounted. There were no really other way to scan it. I didnt use cross polarisation since wood isnt reflective and due to weird angles, direct sun and light changes I had to fully overwrite the direct sun.
While tiling I decided to risk some cross-tile repetiveness and leave some unique color elements, especially that its easy to get rif of them with any color equaliser or color gradient removal tool if needed. Of course I balanced their level so I believe the pattern isnt too repetitive and unless doesnt cover really large flat area without any decals etc. should do the job without any modifications. Color was calibrated with the technique I am testing currently and so far it is very promissing and guaratees very accurate results. While I know it works and it became part of my standard workflow, I am more then sure I will share it in one of my future videos, probably at the beginning of 2022, just need to find some time to make one. So for those interested, please follow/subscribe me on my youtube channel.

The photogrammetry reconstruction itself is based on 139 24Mpx images enchanced with the Dx0 Photolab to get more details from each.
I used AR400 flash light to get rid of any shadows and get very short exposure time, which was relevant while I was shooting with bare hands under weird angles without any additional support for camera stabilisation.
I would say that the flash is very useful for surfaces like this one as it lit the crevices which gives usually missing data to the photogrammetry software to do proper reconstruction. It is even more important if we plan to use the scan to generate alphas for ZBrush etc. and the data in crevices becomes even more relevant to the exposed one.
Anyway, I learnt from this one a lot and was pretty surprised how well I managed to keep the constant distance from the subject surface during this capture. Its probably not the best material of wood, but imo isnt very bad as well ;)
And even if it doesnt cover the standard 180x180cm space as most of my materials do, I still decided to add this one to the library of my environment materials:

I was added as 'gb_wood291_1M'
