Mesh faces are missing after optimization

If your mesh is missing some faces after optimization, it is because some of the faces have bad normals. To quickly fix this issue:

1. Re add the file in Meshmatic and follow the regular import process
2. Once you choose your optimization profile, click on the Edit button to access advanced tools
3. Check if the profile uses the "Remove Internal Faces" tool and remove it
4. Save the profile and run the optimization process
