I don’t know if this is a known limitation or has been noted somewhere (cannot find references to it), but when I import say 5 static mesh lods from an FBX, the 4.4 preview editor build from git it asserts in
and just dies. I would expect it stop importing more LOD’s then MAX_STATIC_MESH_LODS which seems to be 4 as standard and warn about that instead of dieing.
Sorry we did not get to this sooner. Does the crash still occur for you? If so, could you please post your crash callstack and the crash log file that was created at the time of the crash? The log is located in your project’s Saved/Logs folder. Once I have some more information, I will assign a technician to investigate it further.
