Plaster Wall - Photogrammetry based Environment Texture

The third one, and probably the last plaster material in this series. This material is based on the first plaster I made: https://www.artstation.com/artwork/ZGW0eZ
the only difference is that I turned it into a clean and flat surface by covering a slightly different area with the lowpoly model and by treating remining holes and cracks with the AI algorithm ArtEngine offers.
The idea behind this one was to reuse existing scan but turn it into cleaner version without any repetitive elements, so it can be blended together with its aged, crackier and bumpier counterparts.
To get more insight into the photogrammetry process I use please join me on my YOUTUBE channel:

For those interested, the material was added to my gumroads material library with the name 'gb_plaster262':

Marmoset Toolbag 4 - tiling preview video

ZBrush - lowpoly coverage over the highpoly model. As a scale reference I used the ruler visible at the bottom of the scan. Basically I shifted this model slightly higher to cover less destroyed part of the wall to the bottom one covered before.

Seam removal and surface tweaks with the ArtEngine's AI. To get a clean and flat wall I masked out all holes and large cracks, and plugged the mask to the AIs IGNORE input. THis way the AI tiled the texture but also rebuild marked areas.

ArtEngine - the close up with half transparent mask for better visibility to present you areas I wanted to be replaced.
