Tarmac - Photogrammetry based Environment Texture
A surface of tarmac I captured and turned into PBR material using photogrammetry technique.
I used exactly the same workflow and same spot as I presented in this video:

The only difference was that tarmac surface was a few meters away to the previous spot.
Same as before I used rock's cover to avoid direct sun and a monopod to stabilise the camera.
To capture this surface I took 202 images.

My photogrammetry workflow (more details at: https://gum.co/YanD and on my youtube channel: https://www.youtube.com/c/GrzegorzBaranArt
A capture spot defined by rulers. This time I used monopod to stabilise the camera.
A source location details - area defined by rulers with the color checker placed in the corner to be used later for color calibration
Source surface details - I am sorry for poor imge quality but unfortunately this one was captured only as a video :(
Image used for color calibration, adding since might be useful for those who want to give it a try with procedural approach :)

Photogrammetry workflow used for this material (https://youtu.be/DfCH1cjzvmI). It was even captured same day from the same path, just a few meters away from the gravel spot.
