Gravel - Photogrammetry based Environment Texture
Using gravel as an example I tested how Artomatix handles seam removal while dealing with small rocks.
Again it did a job very well and when done I wasnt able to find any transition glitches.
Entire process:
- Capture - Canon80D 24mm F/8 -> 72 images + 1 with the color checker
- PhotoLab2 - RAW image calibration based on color checker values and JPEG conversion for reconstruction
- Metashape - surface reconstruction
- Zbrush - building lowpoly for baking
- Substance Designer - PBR maps baking
- Artomatix - seam removal and surface logic fixes
- Marmoset Toolbag 3 - final PBR test and render
This is my photogrammetry workflow - still experimenting with 'Artomatix' and replaced Photoscan with Metashape (more details regarding to my workflow at: https://www.artstation.com/artwork/K0PYG)
The source - the surface I captured.
I took 72 images with the focal length set to 24mm
The Source - surface details with my shoe, tripod and ruler used as a scale reference
The reference image with the Color Checker I used to calibrate final color in PhotoLab2
Metashape preview - surface reconstruction based on 72 images.
ZBrush - lowpoly coverage over highpoly scan - I covered 180x180cm of real space
Artengine Artomatix in action - in 2D view I masked areas I wanted to be skipped by AI during seam removal and texture reconstruction. In 3D view I preview how texture looks when repeated 3 times
