Orthorectification multithreading hardcoded?

[ManyPixels]

Hi,

When generating orthomosaics, it appears that Metashape orthorectifies images 4 by 4 and the CPU load is way lower than 100% (maximum 30% with 32 threads when "loading" images and 16% under orthorectification charge). RAM is not the limitation (>230Go free), anyway Metashape never cares about the RAM status.

Is there a way to optimise that?

Thanks!
