How can I open up a previous version of my project?

Hi all,

I’ve only been using UE5 for a short while, and I’ve been ‘saving all’ on my project frequently and had Autosave disabled (because I wanted to be in control of when it saved)

A Stylized Dynamic Sky plug-in update screwed up my sky, so I need to open a previous version of my project to save me having to spend hours re-building my clouds etc.

I’ve confused at how the saving works. In Explorer I have my main project (.uproject) and then I’ve got the ‘Saved’ folder - which is where I presumed other .uproject versions would be stored - like the After Effects AutoSave Vault.

Turns out that’s not the case. Everything inside that folder are .uasset files from a week ago, and I don’t see any projects.

How on earth do I access older ‘saved’ versions of my project? Why is it something so crucial to understand, so complicated? (or am I just missing something obvious)

I’ve done the usual YouTube search, but there’s nothing on this subject that would answer my question.

Any help would be much appreciated.

Many thanks
Paul

In my understanding, unreal doesn’t save previous versions of the project like other softwares, you are therefore not able to revert to an older version.

I recommend using something like Git, perforce or plastic for revision control.

It would be smart to start backing up all project files on an external or cloud drive regularly, I do this usually twice a month. Has saved me a couple times

Something like idrive is useful, it will copy anything you changed into the cloud…

Yeah, unfortunately there does not appear to be any direct way of recovering your old project version.

That being said, you have found the auto-save folder with old versions of your uassets. There is virtually no information saved to the actual .uproject and simply reloading any broken assets from the autosave directory should work.

If it was a plugin update that broke your sky, then it sounds to me like you just need to restore the old version of this plugin, which is completely separate from your actual project. Unfortunately, if the creator does not provide older versions of their plugin and you do not have a project that contains this older version, you might be SOL. You could check this folder in your autosaves- you might find any old plugin content here:

I know this is not helpful to you right now, but I will echo what the others have said. Source control is an amazing tool for backing up your projects and I can not recommend it enough. I’ve used Perforce for years and love it. I highly recommend either setting up source control for your projects or regularly performing manual backups in the future.
