Substance Painter 2 crashes after import...

Hi everyone !

I have been using blender for a few years now, and recently i purchased substance painter 2, which is a great tool to create beautiful material.

I import my models from blender to SP2 via a .fbx export.

I frequently have an annoying problem : when i import a mesh with a high polycount, SP2 crashes just after import, and i can’t work.

Strangely, this doesn’t happen if i check the “Create a texture set per UDIM tile” box… but i haven’t been using the UDIM workflow (my UVs aren’t layed out properly for this), and i don’t intend to… plus it removes the names of the texture set (that is to say, the materials you have assigned to each part of the mesh) and replaces them will the UDIM coordinates, wich is kinda annoying if you want to know which part is which…

Does anybody have ever had the same problem ?
