When speeding up transfer in manual fixing for 3D models, reduce polygon density and use compressed, lightweight file formats (e.g., GLB instead of OBJ) to shrink file size.
Smaller files cut upload/download time and make manual tasks like mesh cleanup or UV editing faster—less data means less waiting to transfer and work on.
For scanned models, decimate excess triangles first; this slashes transfer time and lets you focus on key fixes without unnecessary data.
