ReImport All

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: https://forum.unity.com/threads/removing-reimport-all-from-the-context-menu.499663/ )

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:
1. I clicked on Reimport All
2. Unity restarts itself and began loading (or so I thought)
3. 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.
4. While waiting, I came to this forum to check how long other people took, no conclusive answer.
5. I checked the process activity and confirmed (see above) that there is no CPU and memory activity after 1 hour of waiting.
6. I force terminated it again, but this time I started up another test project to make sure Unity is still working.
7. 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.
