Plaster Wall - Photogrammetry based Environment Texture

Hey, this is an old plaster material I scanned recently from glassworks chimney. I followed my standard phtogrammetry workflow which I shared on my youtube channel already:
https://www.youtube.com/c/GrzegorzBaranArt
To get more visual surface diversity when this material is applied I decided to create 3 versions of this material. To to this I also scanned this chimney from the other side. I believe it might be very useful to create version of the material without any dents so it can be blended together. My idea is to shift the lowpoly model position and use the ​​ArtEngine's AI to get rid of dents that remain.
Cheers!

Source - built in 1865. A chimney furnace of brick, standing on waste ground at the Mill Dam, marks the site of Cookson's Glassworks, later taken over by Swinburne.

Source - to capture this area I took 1 image with the color checker for coolor callibration and 125 images of surface itself. I decided to use monopod to take set of pretty close shots with quite wide 24mm focal length. F-stop was set to 8.

Source - shot taken as a height and microdetal reference.. I used my shoe as a scale reference :). Of course I used a real folded ruler as an actual accurate scale reference to define the reconstruction area. I put the ruller on the ground beneath.

Source - for those curious how the top of this chimney look like here the drone shot :)

Source - of course, scanning can be very dangerous sometimes.. . ;). It was a total minefeld around.. Luckily I managed to avoid stepping in.
