Scrambled UVs on import

[mwillis]

I am not sure if this is a bug or some change to the OBJ format.  So, I have a simple workflow of exporting out a high resolution OBJ from Metashape and then importing that in a third-party software for decimation.  Using the latest version of the Metashape, the UVs are lost (or highly messed up) when the low resolution OBJ is imported back into the software.  At first, I thought this was a problem in the third-party software.  I used a legacy version of Photoscan (1.2) and the same model exported and imported properly. So, the problem doesn't appear to be my workflow.

I think something is broken on the import tool.

I have had some weird artifacts in .PLY format UVs as well in 1.6.#

Hello,

Do you mean that the UVs are messed on import only if the parametrization is performed in the external application? Or the problem can be also reproduced just by exporting the model with the texture from Metashape and importing it back?

Mark, can you send a sample PSZ project with the textured mesh only that shows different behavior on export/import in older PhotoScan and latest Metashape versions?
