Framing Distortion

 Framing certainly falls under the "that is pretty complex" category. Since you are taking the pictures from a handful of locations that include the structure the data will appear chunky like that. It will not be able to render the most complex locations which is where the swirls come from.

To render complex things like that a lot of overlap is required but also you would benefit from a higher quality camera like the X5. We have seen it do a much better job at rendering complex things since there is less lens distortion and the image is generally just much higher quality.
