manually increasing tie points

[forumname]

I am working with a challenging situation with nearly featureless objects and low lighting. Metashape therefore has a great deal of difficulty finding tie points and so depth map generation fails. Is there a way to decrease the threshold for tie point generation to get more initial candidates? Alternatively, can Metashape accept tie points added manually, e.g., using SIFT or some other feature tracker? Thank you for any insight.

Either you change the exposure, or you have to shoot for more "visual blending points".
Alternatively, you can set markers manually, yes.

I wasn't thinking of tie points as markers, but you're right, that is one option that is straightforward to implement.
