Holes appearing in exported mesh despite complete Gaussian rendering

[lipsmith0701]

After training, I exported the mesh, but it contains noticeable holes. Interestingly, the Gaussian rendering appears complete with no gaps.

Additional context:

• All points were used for mesh construction, so the issue does not appear to be related to point sampling.

• The discrepancy is only visible in the exported mesh, not in the rendered outputs.

Could you help explain what might be causing this, and suggest possible ways to resolve or debug it?
