Gravel Pit…
Recently my Dad had some gravel delivered to his house and I happened to have my camera with me and took some shots for 3D scanning. Here is the low poly result as rendered in Marmoset Toolbag 2 with extracted Normal, Height and Ambient Occlusion from the high res model and hand painted Albedo and Roughness maps. Unfortuantely I didn’t take enough source images for complete photogrammetry, so there was a quite a bit of reconstruction involved.
