Rusty Metal - Photogrammetry based Environment Texture
A rusty metal surface I turned into PBR material using photogrammetry. I think this might be the type of surface where photogrammetry isnt the best choice and where image to PBR technique would work better. I spent ages trying to setup this material in Substance Designer anyway. The scan itself was crap as hell.. subject was just 1 meter wide.. reconstruction result was very patchy and terrible to work on.. after I masked everything out in Artengine just a few percent of surface left.. fortunatelly AI did the job and reconstructed missing parts.
I use tripod to capture this surface but the weather was in constant change. Anyway.. finally I managed to turn this this terrible scan into something useful :).

Big thanks to those who did it already
Cheers!

Source location :)
Source location - capture surface with my shoe as a height and color reference
Image with Color Checker used for color calibration for those who might find it useful as a color reference for procedural materials
Metashape - reconstruction based on 99 images. I managed to reconstruct 44mln dense highpoly model but I used 16k texture to carry albedo for baking
Zbrush - lowpoly coverage over highpoly. It is larger since I wanted to recreate 2 by 2 meters large area. I was hoping AI is going to fill missing parts later.
Substance Designer Baker settings
Artengine - since reconstruction was a total disaster I had to mask really a lot of crap and let AI fill it with something better.
Additional tweaks and building metalc map in Substance Desgner.
