Rock - Photogrammetry based Environment Texture
Another rocky surface captured to practice photogrammetry. Wall was still covered with snails.. but not as dense as previous one. I reconstructed that surface from 10 images taken from long distance. I used 70mm and f/8 setting for camera. I used backpack to stabilize my camera due to strong wind.
My current workflow
Funny thing, as there was a pathway along the wall I was shooting I was asked few times by different people walking nearby, what the hell am I shooting as sea is on the opposite side. Better than being interrogated by the police for pavement shooting ;)
Source - captured with 10 shots (70mm, f/8) ..
.. and reconstructed as 11mln highpoly model in Photoscan.
Zbrush - lowpoly over highpoly
Substance Painter - seam removal
Substance Designer - graph to process albedo, normal, ao and bent normal maps into final PBR textures
