How to fix missing parts in photo 3D models?

To fix missing parts in photo 3D models, address insufficient photo coverage or use 3D tools to patch gaps. If the area was poorly captured, take more angles and reprocess the model with software like Agisoft Metashape. For gaps you can’t rephotograph, use Blender’s “Fill Hole” or MeshMixer’s “Auto-Repair” to extend adjacent geometry and textures. Small gaps often fix with automatic repair features; larger sections need combining rephotography and basic manual editing—no advanced skills required.
