I keep trying to import fbx files, after every few it will close out after I click “import”, it is with certain fbx files, it wont happen with every one,. Its ticking me off that I can’t import them.
Try to re-export you fbx file and then try it again. Also make sure to post the log file (project-saved-logs) 
Hi Theoneman,
Can you tell me what version of the editor you’re using? What modeling software you’re using?
With the FBX in question you mention it’s only with certain FBX files, would you mind sharing one of the assets or make another simple asset that can get the same error? This will allow me to test on my end and if I can reproduce I can see what steps need to be taken to correct the issue. If you don’t want to post a link here you can always send one via private message to me here on the forums.
I’ve not encountered this problem before so I’m most interested in trying to figure this one out.
If you’re repro steps are more than just export FBX from modeling software and import into UE4 can you please explain your steps?
Thank you!
Are you trying to import FBX with 4 or more LOD’s?
Two things come to mind.
1: If your fbx exporter can do it, use linked references to image textures instead of baked-inside-the-fbx
2: If you have a transparent material in your fbx and said transparent material has already been defined as transparent in UE4 AND you’re using LPV AND you’re in Lit mode, you can get a crash. Just go to unlit mode while importing and selecting the mesh.
