For some reason, I can only scroll the Unused Assets view with the mouse wheel while the cursor is above the scroll bar. It doesn't do anything while the cursor is above one of the assets. Holding right mouse and dragging (the universal quick scroll gesture in Unreal) doesn't do anything either.

• add latest ue5 support

Really nice update with the tree view! However there seems to be a regression, all our blueprints that are primary assets and the assets used by them are now listed as unused.

Exclude assets from list.
Also assets that are excluded, their all related assets also removed from deletion list, to prevent asset corruption.

When user deletes unused assets, empty folders also will be deleted automatically, if user check that checkbox.

Hey, i cant open a Project in UE5 Preview

Hello Ashot, sometime when I do Clean Project it deletes my LevelSequence assets when I have excluyed the folders and classes. I think it could be the FixUpRedirectionFolder too but Im not sure.

• add view option "Show Folders Unused Only", enabling which will show only folders that contain unused assets
• optimize items creation performance
• add hide/show column feature
• add reset default setting option (maybe globally)

This plugin is really nice and it would be awesome if it also supported cleaning up plugins

I'm looking for ways to set up a pipeline for a big project to show warnings when unused assets are being pushed to repository.
This plugin's Python API is really useful for that, however when running on the actual project that has around 200-300 GB of assets (which is why we're trying to reduce it) both the editor and the commandlet crash with "Out of memory" trying to allocate 80-100 GB array.

I'm not really sure what percent of assets are loaded at the point of the crash, but I expect that even if i had 128 GB of RAM available, I would still probably run out of it on the next array allocation when more assets are loaded.

Is it possible to introduce some sort of dynamic loading of assets while they're being checked and unloading when the check is done? Or maybe some other way to drastically reduce ram usage?

Here is the stack trace from Crash Reporter:

Hey there!
I've installed this plugin a few days ago, but since I've installed it I keep getting: "Failed to delete some assets". (it's actually not deleting any assets at all).
I've tried redownloading and reinstalling the plugin but it didn't help. I'm using Unreal Engine 5.
Any help is appreciated, thanks! :)

I've implemented compilation fixes for building under Linux against 5.0.2. It's all pretty much minor stuff. Clang v10 appears to be more strict than the Visual Studio compiler.

Have a look at https://github.com/ahrbe1/ProjectCleaner/commit/c5c5bdbfc793c9037914853760147443782aa4e2

Two functions appear to be deprecated and resulted in warnings, so I updated those using the recommended APIs. Though that part may need to be checked against 4.2.x to ensure it still compiles. Those functions are GetAssetPackageDataCopy() and GetCachedEmptyPackagesCopy(). They aren't strictly necessary for the Linux build, though.

I can open a PR if desired.

Can't use it, clicking "Scan Project" gives an error.

Hi, UE4 has feature to blacklist files when packaging. Instead of deleting from project, can u export the unused files to PakBlacklist-xxx.txt to use for packaging instead of deleting from source project.

In ShooterGame example project assets like "DefaultShooterButtonStyle" class deleted but they used in code.

const FButtonStyle* ButtonStyle = &FShooterStyle::Get().GetWidgetStyle<FButtonStyle>("DefaultShooterButtonStyle");

DefaultShooterButtonStyle - path is

SlateWidgetStyleAsset'/Game/UI/Styles/DefaultShooterButtonStyle.DefaultShooterButtonStyle'

When assets deleted, a lots of empty folders may remain in content browser. By adding this option we can automatically delete empty folders after assets deleted.

Got a crash when I try to open Project Cleaner.

• add option for filtering data based on path
• optimize scan methods, performance should be ok, even on large projects
• all scan logic must be in subsystem class (but not exposed to blueprints, for blueprints we will use separate AsyncNode)
• must have multiple choice of scanning
  1. Via user interface of plugin
  2. Via Blueprints (Async node will be available)
  3. Via Commandlets
  4. Via Python scripts

User can pick amount of assets to delete at a time. This is to prevent Engine to Freeze

Delete assets in chunk. Like 100 at a time , or maybe expose as a input parameter to plugin UI for user to pick, based on user PC characteristics.

It crashes when you have a Utility widget open in the layout.

I got project singleton set to blueprint deriving from c++ class, it got deleted despite of being directly in excluded folder (actually also some other blueprints got deleted residing in sub folders, should sub folders be added separately?)

Based on request of users(like #29), it will be good decision to expose some API functions used in ProjectCleaner itself.

I get a message saying "failed to scan the project because not all Redirectories are fixed but I've fixed up Redirectories on the main content folder already, I tried reinstalling the plugin but the issue wasn't solved, I'm using UE5.2.1 Source

Hi,

Excited to try this. Does it work for UE 4.26?

Thanks

Assets with specified classes wont be deleted.

Example:
Textures - 123
Materials - 12
Blueprint - 2

etc.

Hi, I found a bug that somehow AnimSequence, LevelSequence, SoundWave, SoundCue, and DataTable are labeled as "UNUSED" even though it's being used in the project.

Note:
Engine UE 4.27

The tree view is working really well, but I noticed that the folder tree shows every folder in the project, rather than only ones that actually have unused assets in them. Is it possible to filter the folders and hide ones that will display "no assets"?

I installed the plugin for newly released 5.0.3, it causes an error and prevents opening the project. The update might've broke something in the plugin.

Great plugin! This the first one of these kind of plugins that I found to actually work properly (doesn't mark primary assets, assets used by C++, etc).

Currently you get all the assets sorted by name, which is a great start, but it can be difficult to investigate which groups of assets you want to keep and which not.

When you have a large amount of unused assets in the project, it would be very useful if the Unused Assets tab had a tree view for the directories they're in. Then you could very quickly drill down which folders are useless and which ones are known to still be needed for some thing in the future, or quickly isolate folders that aren't related to your work and you're not sure about.

Assets used in levels that using world partition system marked as unused. Those assets stored in /Game/_ExternalActors_ and /Game/_ExternalObjects_ folders. When scanning , all those external assets marked as corrupted.

Problem might be in GetRootAssets() function.

This option let users to pick specific classes to delete.
Like delete only unused textures in project.
