Hi Ben
Yup, you need at least 3 images per CP/COMPONENT, if you get say 5-7, it’s OK in most cases. Try to get 3-4 CP per image as this helps ALIGNMENT to estimate data properly.
A second option would be to increase CP weight from the default 10 to say 20-50. But just after you’ve added CPs and tested the alignment with them, just then change the weight…
