Rock - Photogrammetry based Environment Texture
Still experimenting with Artomatix and its AI. As a subject I picked generic, flat, rock surface. Artomatix so far simplified my workflow a bit. I dont have to generate bent normal based heightmaps. It handles all baked heightmaps very well so far. Unfortunately AI struggles with human made patterns like bricks, cobblestones etc. Also compared to my previous material, I introduced 'Levels' node which helps to better control albedo output value and 'gradient removal' node which helps to calm down the albedo.
Here is my current photogrammetry process:
- Metashape - photogrammetry reconstruction
- ZBrush - building lowpoly for baking
- Substance Designer - PBR texture baking
- Artomatix - sema removal and texture rearrangement
- Toolbag3 - final material testing and 'ball' ;) rendering
This is my photogrammetry workflow - this time as an experiment, I introduced a new software - 'Artomatix' (more details regarding to my workflow at: https://www.artstation.com/artwork/K0PYG)
The reference image with the Color Checker I used to calibrate color in PhotoLab
The source - when I captured that wall it was hidden in shadow already, unfortunately missed that one and this is the only perspective shot I have to show the context.
Metashape (successor of Photoscan) - camera positions and 3D reconstruction in Photoscan based on 74 images.
ZBrush - lowpoly over highpoly surface coverage in Zbrush.
Artomatix ArtEngine - entire graph which was used to process final material (in 2D view you can see fast mask which tells AI to remove marked areas during reconstruction process)
