I get the error message Failed to import ‘…/…/…/…/…/…/Users/name’. Failed to create asset ‘/name’
either the name has some characters that arent allowed, or your folder structure is too long.
I think the limit was 256 characters for the whole folder structure.
can you show us the file in question, its name, and folder structure?
Hey Luos, you sure you don’t work for us? 
As Luos mentioned we’ll definitely need some more information to proceed.
Please also include your Log file from the Project Folder/Saved/Logs.
You may also want to check a later build like 4.12 or the 4.13 preview. There is over 8 months worth of fixes and changes in these latest builds that may have already resolved an issue with what you’re importing.
K thankyou Ill try those fixes
This is the message I am given:
Failed to import ‘…/…/…/…/…/…/Users/famil/OneDrive/Documents/Unreal Projects/VRPlayroom 4.12/Content/InfinityBladeGrassLands/Environments/Misc/Exo_Deco02/StaticMesh/laserpistol.fbx’. Failed to create asset ‘/Game/laserpistol’
or originally
Failed to import ‘…/…/…/…/…/…/Users/famil/Desktop/Lazier~Pistollez/Vitrolique Poquette neutrali2eur/laserpistol.fbx’. Failed to create asset ‘/Game/laserpistol’
yea, your folder structure is too long.
its better to place ue4 and its content on their own drive, or at least put it all in a folder closer to main drive folder so your structure would be more like C:/UE4projects/projectname/projectcontent that will solve it!
