FBX export ultra slow on Windows !!
« on: January 31, 2019, 01:57:21 PM »
I am exporting a 134 million faces mesh with vertex colors as FBX on Windows and after 3 hours the mesh export is still not complete. I exported smaller meshes with the Windows version before and this was also extremely slow (not that slow though, but mesh was smaller). Comparatively I have been using PhotoScan on a Mac and even though i didn't export such large meshes (can't because not enough RAM), comparatively to the Windows version it seemed to me the export on Mac was way faster. PhotoScan Standard 1.4.1, 64GB of RAM on Windows, 32GB ram on Mac.

Hello jackiehumzad,

Can you consider using different export formats, like Alembic, for such large mesh export? I also suggest to try version 1.4.5 or 1.5.0.
Best regards,

Old post revival, but this is still happening with latest version.

FBX 1Mil export takes too long.

 just my experiences.:
I export 130mio fbx with current version in ca 1h but this is nearly the limit. obj support better export within 300-400mio polygons but in this ranges it need always 1-2h+ to export (I have 128gb ram).

A automatic tiled mesh via metashape would a big step for users in future!  ;)

To generate a 300mio mesh is not that big challange throught depthmaps.. but the export and further handling in one file is.

Alembic is faster, right, but Substance Designer does not accept abc files. What do You use to convert abc to Substance Designer compatible mesh ?
