Abstract: The initial photogrammetry of this object was very noisy as photo alignment was not perfect. The main culprit was non-ideal visual features due to high reflectivity and the harsh sunlight combined with a generally flat and featureless surface of the object.
The initial pathing for this object could not capture all the necessary aspects to form a complete model.
