Learn from me, don’t ever click this option from the context menu. Ever.
p.s. Why is this an easy-to-click option in a context menu?
This should come with a modal - Are you really really sure you want to do this?
What happened? Unless there’s a new bug, that’s safe and also recommended to use after a switch of editor versions.
You mean re-import all? Yeah depending on the project it can take many hours. It being in the context menu has been a complaint for many years.
(for example: Removing "Reimport All" from the context menu )
I too have become unable to work for hours because of a misclick.
But it has an extra confirmation prompt these days, doesn’t it?
Oh, it may be reimport all…
I don’t want to try it again to verify if it has a confirmation!
I’d love a setting to remove it from the context menu though!
It does:
I do agree the right click menu is a weird place for it. It’s a rare operation, not sure what it’s doing there. (plus I prefer deleting the library when I intend to rebuild it, seems cleaner, so in my case I never click it intentionally).
I had selected a few prefabs and mistook it to reimport all selected. That’s what I get for not reading!
Yeah, fair enough.
My root folder, i.e. Assets and everything outside is 1.5GB… how long will it take to re-import all :(
I just clicked on thinking it will just reimport a few selected .fbx files!!
That’s not too big. How much time it will take depends on how many textures you have and what compression settings you’re using.
It has been 1 hour already… roughly how long do I need to wait before giving up and force quitting? How do I know it is indeed processing? Thanks.
Doesn’t it have a progress bar that says what it’s doing?
What’s your system? Is the project on an HDD? Is it a lot of mostly small files?
@AcidArrow this is how the progress bar looks like, it doesn’t look like it’s moving.
I am not using any fancy set up. The files are on my internal HDD.
How do I repair it if it fails to reimport again and again?
Yeah, I thought that might be the case. Unity’s Library cache consists of a large number of small files which is very slow on an HDD (small files spread across the platter caps out at 0.5MB/sec for most HDDs). I’m guessing based on the wording that your SSD is an external drive?
For anyone else who finds this post in the future. The steps I took leading up to successful Unity start up goes like this:
- I clicked on Reimport All
- Unity restarts itself and began loading (or so I thought)
- I waited for 30 mins and force terminated it because the progress bar was not moving, then I attempt to re-open the project again.
- While waiting, I came to this forum to check how long other people took, no conclusive answer.
- I checked the process activity and confirmed (see above) that there is no CPU and memory activity after 1 hour of waiting.
- I force terminated it again, but this time I started up another test project to make sure Unity is still working.
- With the test project still opened, I got to the File menu and re-open my actual project. This time, the progress bar was moving actively and the splash screen is updating quickly. In less than 20 mins, whole project was loaded.
Hello. Sorry for opening an old post. My grandson who is 10yrs old has been doing a project for a couple months. I installed an external hard drive for more room. I did not intentionally move anything with unity. The computer did crash was the same day. Now when he opens his project. He gets 109 errors saying this: a meta data file exists but its folder can’t be found and has been created. Empty directories cannot be stored in version control, so it is assumed the meta data file is for an empty directory in version control……I checked the folder and all the meta data files for the assets are still there on the computer. But unity can’t seem to find them. I’m not very good with computers and grand son is crushed. Could some one point out if reimporting all assets? Could fix this? Or something else to try. Much appreciated for the help
A plugin I was working with told me I should ‘reimport all’ to get some textures to load.
That was a bad idea, I lost a entire days worth of work due to my scene being reset. Everything is gone.
You gotta get into the habbit of pressing Ctrl+S every now and then (while in the inspector or scene window). The same would have happened in the case of a Unity crash/kill (bug of Unity or e.g. because you coded an infinite loop).
At least not having saved the scene is the only reason that comes to my mind why that happened to you since reimports are not meant to modify the scene.
It was saved, but that doesn’t matter because ‘reimport all’ overwrites it.
You may have encountered a bug. What version of Unity was this in?
When you click Reimport All it first shows you a message that explains that it will delete cached data only (that means no actual content like scenes is deleted)!
Then if your current scene was not saved, it even prompts you to save it.
Have just done it in an Unity 6000.0 project and all changes were preserved.
Please do not scare people away from a functionality that does solve certain other problems.
