Tree Trunk Photogrammetry

Photogrammetry with smartphone (S8)
My morkflow:
Import the Highres Model from RealityCapture to Zbrush. Simplify the Mesh with Decimation Master. In this case from 4 Million to 35k.
Apply a new uv layout to the 35k mesh, reimport it to RealityCapture and create the albedo texture. Then bake the maps (normal, ao etc) in SubstancePainter and create the textures (Albedo, glossiness, metal etc). Render in Marmoset.
