"Bad MeshDescription" causing crash

[TheEnglishBeat]

Hey all. I fixed up redirectors after moving something and the program crashed. There seems to be a specific static mesh giving me issues but I’m not quite sure what to do with it. Editor crashes before project starts up.

Assertion failed: Owner->IsMeshDescriptionValid(0) [File:D:\build++UE5\Sync\Engine\Source\Runtime\Engine\Private\StaticMesh.cpp] [Line: 3048] Bad MeshDescription on /Game/StaticMeshes/Rings15ilm.Rings15ilm

Hey @TheEnglishBeat!

It sounds like you did some moving and the fix-up didn’t go through right. The files got physically moved but not updated correctly afterwards. Try opening the project in Windows explorer and moving the files back to their original locations!

[TheEnglishBeat]

Thanks for the quick reply!

I did that and I can at least get the Editor to launch! Score!

But when I try to use any of the files I moved… it crashes and gives that error again… in any way, including moving them within UE5.

Well dang. It’s possible they’ve been corrupted.

I hope you have a backup! It’s always important to back up your files as often as possible.

You may need to delete the files you moved if you don’t. I hope it wasn’t many!

[TheEnglishBeat]

Oh my god. It’s working.

Yeah these files were recently made, I was fixing up before creating this backup haha!

It’s no big deal to delete them, I just used Windows and deleted them there and everything seems to be back to normal minus the 3 static meshes… I can remake them in a jiffy.

Thanks for your help, that did it!
