Reimporting FBXs has suddenly slowed down significantly

Development Getting Started & Setup
1

For the first several months of a project, reimporting FBX files took around 5-10 seconds at most. Last week it suddenly starting taking over a minute. Some notes;

  • FBX are super simple assets, around 100-200 verts.
  • I noticed the little window in the bottom right that tells you a file has updated stopped.
  • Have made sure ‘show import dialoge at reimport’ is still enabled, it is
  • FBX is updating with the changes I made

Here is my latest log;

Updating Unreal seems to have resolved this issue. I still don’t get the sliding reimport update in the lower right but it imports very quickly now.
