We have been using Pix4D for about 1 year and have processed number of sites , with no issues previously. One of our recent project site is showing big blank areas on the outputs. We flew drone twice on that site, used different keypoint image scales (based on recommended settings for agricultural sites https://support.pix4d.com/hc/en-us/articles/202560159-How-to-improve-the-outputs-of-dense-vegetation-areas-#gsc.tab=0) , and every time output products have huge blank area all over.
Attached are few screen shots of how my project is looking like after processing. On the second screenshot, you can see a portion is hanging out at a weird angle outside the project boundary.
Any thoughts or suggestion would really help.
