Sand - Photogrammetry based Environment Material
A material of dark sand - I made this one practicing the photogrammetry workflow with the ring flash and cross polarisation. This way I wanted to improve the quality of materials I create. I have also improved a way for color calibration but need to process a few more tests before I share anything about it. Anyway, I am planning to share a bit more details about this type of captures in my next video which I plan to publish on my youtube channel soon:

Also since I am quite happy with this material, as promissed I am adding it to my Material Library. It can be found there as 'gb_sand281'

Source location - I captured this sand by taking 156 images with the flash based cross polarisation setup.
My shoe used as a scale reference for the height.
Drone shot of the beach with the sand to show how relative things really are to each other

another macro zoom shot to show how relative things really are to each other ;). It looks way better on a video.. I guess I should make one at some point.
Metashape - camera alignment and photogrammetry reconstruction based on 156 images.
ZBrush - lowpoly model positioning for baking. I used catured rulers as a scale reference
ArtEngine - I used artEngine to tile this one as ArtEngine is designed to tile materials like this one. Since I messed with the highpoly model and I cut part of it by accident, I used ArtEngine's AI to reconstruct this missing part :D
The material and texture set was added to my material's library:
