FBX export ultra slow on Windows

[yoli]

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 yoli,

Thank you for reporting.

We'll check that, however, can you please specify, if such large models are useable in any other applications and what are the purposes of such high-poly meshes?

The purpose is to generate 8K textures from vertex colors. 8192*8192*2= 134.217.728 (double density for safety since the mesh is not flat).
