Rock - Photogrammetry based Environment Texture

This material is the result of scan I made for my last video tutorial (https://youtu.be/fRRiEXtQuOk). By creating this material I was trying to answer the question, is it possible to create high quality photogrammetry based environment materials if I use a Mavic 2 Pro drone instead of DSLR camera to capture the surface. If you like this material the answer is yes :)
Shooting with the drone is a kind of trade with the DSLR approach.. we trade the image quality (about 5%) for totally free camera positioning in space during the capture (priceless for surfaces like this one).
The best way to go into details is simply to watch the video I made. It is about 1 hour long and is free on my youtube channel.
I also made to more thigs differently to my standard workflow. I did delighting pass while still working on 14 bits deep color data and I wrapped the lowpoly model using projection in ZBrush - both seems to be a good decision.
Hope you enjoy it and find something useful for you here. Cheers!
