Problem with Mesh output of PhotoScan scene with Metashape

[OakCorp]

Loading a Photoscan project with Metashape 1.5 (1.5.2) and outputting an OBJ mesh results in no smoothing.

There is no problem with meshes generated from alignment in Metashape 1.5.

The normal is output to OBJ.

What is the cause?

Hello OakCorp,

I think that the issue is related to the coordinate information used. It looks like the model has been reverenced in some projected coordinate system with large Easting and Northing values for X and Y coordinates, then the model has been exported in the very same system, but the post-processing application cannot handle large values for coordinates and truncates some digits.

I can suggest to use Local Coordinates option on export or apply Shift for X and Y in the Export dialog to subtract large base values from the coordinates of the mesh vertices.

thank you for the advice. I will try it.
I will explain that to my customer.

Best wishes,
