Rock - Photogrammetry based Environment Texture
Another photogrammetry based surface of rock. This time I tested how Artomatix handles lack of information.
Since to get this surface I captured jsuit about 1x1 large rock rock area (not 185x185 cm), to keep correct proportions I simply covered wider area with the low poly model for baking. When done I masked them in Artomatix and let 'AI' to replace and reconstruct missing data. In a few seconds it turned broken material into fully functional and high quality one :).
To get albedo even more consistent I gave a try to '"Gradient Removal" node, unfortunately I wasn't very happy with the result.. I believe I need to wait for more advanced PBR tools or just give it another try next time.
As a light source for material render and live preview I used a new 360 Panorama HDRI map. This map is going to be included into my new incoming HDRI pack :).
This is my photogrammetry workflow -this time I continue my experiments with 'Artomatix', so far it made PS totally redundant and and left less worrk to Substance Designe (more details regarding to my workflow at: https://www.artstation.com/artwork/K0PYG)
The source - surface I captured. Quite hard to estimate its size without any given scale context :)
Here is myself scanning as a context for scale ;).. as you can see those rocks are quite huge.. not super huge but not as small as they might look like without me.
The Source - surface details with my shoe used as scale reference.
The reference image with the Color Checker I used to calibrate final color in PhotoLab2
Metashape preview - surface reconstruction based on 36 images.
ZBrush - lowpoly coverage over highpoly scan
Substance Designer baker settings.
Artengine Artomatix in action - in area painted with white in 2D view you can see how much data was cut from reconstruction. AI had to recreate entire space based on whats left and I have to admit it did it pretty damn good :D
The 360 HDRI Panorama preview I used as a CG light source for still render and live preview.
This is the one from my new incoming HDRI Panorama pack :). This preview file is in lower since have to downsize it a bit.
