Nino, it depends on the accuracy you require from the mesh you are generating.
A mechanical shutter gives a much more precise image, which will translate to a more accurate mesh, since there is less distortion in the images. (by distortion I’m talking about rolling shutter distortion, which can’t be compensated for by any software)
Is there a difference between a global shutter (Mavic) and mechanical shutter (Phantom 4 Pro)? Yes, but unless you’re shooting images for crime scene reconstruction or some other research which demands the best quality images, most other cameras will be sufficient.
