Autumn Leaves - Photogrammetry based Environment Texture
Another photogrammetry based environment texture I made. Same workflow but two significant changes within. To improve my current pipeline I introduced new seam removal plane which covers additional 20% of total uv space. I have updated my photogrammetry tutorial with details ( https://gum.co/YanD ), and have added that plane as additional tool 'uv1:1.2 plane' for seam removal in Painter. So everyone who has bought my tutorial already please download both files as both were updated: Guide and ZIP archive.
I also experimented using four markers instead of two to improve navigation during capture. In result I managed to improve coverage consistency and avoid under and overshooting.
My current workflow - you can find all the details in my recently released photogrammetry guide: https://gum.co/YanD
For those who bought it already: please get latest version as document and tools were updated today. 5 new pages were added.
Source Location - I took 321 photos to capture that surface (focal length set to 35mm and aperture to 8). To improve navigation accuracy I used 4 aluminium foil balls. Area covers 2 square meters
Surface height with markers and scale reference :). I have found that capturing shoe is frame is really useful as scale reference.
Color Calibration - Auto White Balance (camera's guess) vs Custom White Balance (reality)

ZBrush - Lowpoly over Highpoly
Improvement I introduced: new 'Seam Removal Plane'. Main uv space 1:1 is marked with green. Area around is tiled so it is much easier to remove edge glitches during seam removal on sides.
