there is no need to create a vdb, but it works yes
Grzegorz Baran has recently presented his latest photogrammetry experiment. The artist created autumn grass texture with the help of Photoscan, ZBrush, Photoshop and Substance tools. Grzegorz has also shared a short breakdown, so let’s study his production process.
Reconstructed into 39.5mln highpoly mesh from 179 images. I used Canon kit lens with focal length set to 35mm and aperture f/8. This is focal length I get the best results while scanning grass. I believe that 50mm would be even better, but takes too much time to capture as frame is too focused and needs even more overlapping. 24mm for grass doesn’t work very well as it has over detailed height differences. For tarmac I would definitely use 24mm.
