Here is stone wall I scanned from one of the old building in Vila Nova de Gaia (Portugal). Length about 4m.
It has 4x4K textures, so the quality should be quite good. Normal Map reprojected from 26M high poly mesh (you can download it from additional files).
Created in RealityCapture from 216 images.
Feel free to use it for your personal projects.
Please contact me if you have any questions about photogrammetry. I'll be glad to help!
