Hi there,
I am shooting using a 360 turntable on a black velvet with a strong flash and cross polarization.
Though an issue I get is that it seems that Metashape is able to pickup dust particle and/or the surface of the black velvet and uses this to align pictures.
As a result, each series done after rotating the object on the turntable end up aligning on the same exact path, which is wrong.
I use darktable to process my images and apply white balance, color calibration (color checker) and exposure.
How do I exclude those particles during the alignment step so that each camera path is well recognized and avoid black artifacts in the model?
In the 4 pictures I attached:
1. Original picture
2. Picture with all depth map levels
3. View of the model and alignment
4. Settings used during alignment
