Hello lads, **Im using 4.23.1** :

-Working a mesh in **.obj** format

-Reimport the mesh as I make changes to it, everything working fine

-Last time **I reimport I clicked something** I dont know what

-Now **all meshes** that I import **make 1 material slot** for the entire mesh **instead of the ones I set up**

-Searching and **tweaking the import settings without results**

-Somehow search in the internet, couldnt find anything

-Re-making the entire project is not an option

**Gentlemen, any clues?**

Have you tried not working with .obj if I remember correctly Wavefront loses a lot of information on export such as rotation materials relative location etc… FBX is your best bet.
