Hi!
I have been stitching Sequoia with Photoscan. It asks me whether I want to combine the bands to which I say 'yes'. I use a regular workflow and all the images seem to align. The DEM looks fine, everything looks fine. But when I export to an orthomosaic, a large chunk of the ortho is empty (see attachment). I also added an image showing what the complete coverage is supposed to be (based on stitching without combining the bands).
I saw this behaviour on both Agisoft 1.3 and 1.4 for this specific dataset. Other datasets do not have this issue. Does anyone know what is happening?
