Gravel - Photogrammetry based Environment Texture
A gravel material based on scan I made about 3 years ago. I didnt use anything special for camera stabilisation and due to surface complexity I wasnt able to get any decent result from it until recent Metashape update and its full 3D (Arbitrary based on Depth maps) reconstruction mode. Material was tiled with Artengine, it did very good job in just a few seconds, unfortunatelly I have noticed a few logic glitches (a few rocks were merged into one).
To get more details about my workflows follow me on my youtube channel:

Big thanks to those who did it already :)
Cheers!

My photogrammetry workflow (more details at: https://gum.co/YanD and on my youtube channel: https://www.youtube.com/c/GrzegorzBaranArt
Source location - captured area unfortunately without any scale reference. Captured about 3 years ago
Source location - height/surface details with my shoe used as a scale reference
PhotoLab - image postprocessing and color calibration with additional delighting pass for albedo using 'selective tone' tools
Metashape - full 3D reconstruction based on 71 images. In result I generated 60mln dense highpoy model and 16k albedo texture for baking.
ZBrush - building lowpoly model to define the space for reconstruction
Artengine - AI based seam removal
