Digital replica — troubleshooting common issues

Symptom-driven recipes for the most frequent problems encountered during the Digital Replica workflow. If an issue is not covered here, consult Digital replica — best practices and QC first and then open an issue on the 3DSC GitHub repository.

Common Issues and Solutions

Issue: Mesh has holes after decimation

Solution:

  • Check original dense cloud quality

  • Increase photo overlap in problematic areas

  • Use Metashape’s “Close Holes” tool before decimation

—

Issue: Floating geometry fragments after segmentation

Solution:

  • Enter Edit Mode (Tab)

  • Select unwanted fragments

  • Delete faces (X > Delete Faces)

  • Use knife tool (K) for precise cutting

—

Issue: Texture seams visible between tiles

Solution:

  • Increase texture resolution in problematic areas

  • Check photo quality and coverage

  • Use Metashape’s blending mode “Mosaic” or “Average”

  • Apply color correction in post-processing

—

Issue: LOD generation fails or crashes

Solution:

  • Save file before generating LODs

  • Reduce number of simultaneous tile processing

  • Check available RAM and disk space

  • Try generating LODs for tile subsets

—

Issue: Georeferenced coordinates cause offset in Blender

Solution:

  • Use 3DSC shift file import option

  • OR work in local coordinates

  • Maintain coordinate system consistency across all exports

—

Issue: Texture resolution lower than expected (>1.2mm/texel)

Solution:

  • Verify tile area calculation (see Texture resolution formula)

  • Increase number of textures per tile (modify script)

  • Check photo resolution and GSD

  • Ensure photos used for texturing are sharp
