DJI Modify Flagship (Permanent) is the perpetual licence for DJI's intelligent 3D model editing and refinement software, used to clean up, repair, and polish models generated in DJI Terra. Features include AI-assisted mesh repair (floating part removal, hole filling), texture optimisation, and seamless Terra-to-Modify project handoff with one-click activation — making Modify the natural finishing tool for survey-grade and presentation-ready 3D outputs.
