I have a project with 114 photos, all of which are aligned, and refined camera calibration values look good (i.e., close to the initial values and with only small changes between photos). Building a model from the sparse point cloud also works well.
However, when I want to build a model using lowest, low or medium (haven't yet tried high and ultra), most photos are skipped and depth maps are build for only 21 cameras. What could be the reason for this?
