Is the 3D Mesh used in the creation of the Orthomosaic?

Pretty straight forward question per the title. I know this is an option in Global Mapper’s Pixels to Points tool, claiming higher quality orthomosaics from the process.

My question is do I get any benefit in the orthomosaic from creating the 3D mesh within Pix4DMapper, or can I skip that step if I don’t need the 3D mesh directly? Also, are there benefits to the creation of the point cloud from the 3D mesh?

I’m trying to cut down on processing time and storage capacity usage without affecting the end result.
