Asset Hunter (Project cleaning tool)

Hey all.

I installed Asset Hunter Pro with the goal of finding and deleting the many unused textures in my project. I did a build and clicking on the list of "Unused" assets, and it's showing many textures that are in fact in use, some in several scenes.

Any ideas what am I missing here?

Unity 2019.4

 

Hi vice

Sorry to hear you are having problems. It should definitely not happen that referenced textures shows up as being unused.
My first though is that the scenes that are using those textures are not added to buildsettings?
If the scenes that reference the textures ARE added to buildsettings, then I need some more info about how? Is in stored in the scene itself, is it loaded at runtime, through asset bundles? through addressables?

You are welcome to respond here, but you can also write me directly at contact@heurekagames.com

 

Yes, that was the problem. I didn't realize it took into account only the scenes that are in the build settings.

Thanks

 

Hi vice,

Asset Hunter doesn't seem to work properly with addressable assets when they are referenced by AssetReferenceXXX classes. All assets and their dependencies are marked unused.

 

Hi, I have mailed you as well and though if you received it or not. I am using your asset which I bought a few weeks ago. It's very helpful in many features but I am facing a difficulty in having view of assets by TYPE. As you can see in the image attached, though I have clicket SORT BY TYPE but still it is sorting by name. I am using unity 2019.4.5f1. Can you please have a look.

 

Hello! Upon initial setup of AssetHunterPro, it begins building for about a minute and then crashes with this error. It is a pretty large project, but I'm not sure why it keeps crashing? I am using Unity 2020.2.1f1

 

import that and this error pops up,imported it on a empty gamy project
unity version: 2019.4.15f1

 

I kind of miss this functionality as well. Especially when cleaning up after importing third party assets. They are all in different root folders, so they aren't subfolders. Maybe only disable the option of the selected folders are subfolders?

Or optionally disable the auto rescan after deleting, because that costs the most time.

 

Hi Leniaal, thanks for your feedback. Its great for me to hear what you guys think so I can continue evolving AHP.
I will see what I can do to alleviate this problem

 

@Kristianlhj Any news on this?

 

Still waiting to hear from your side. Thanks.

 

Hi GameHourStudio

So sorry for not responding to your pervious post. Dont know what happened - completely missed it for some reason.
Just tried to reproduce your issue, and it does indeed seem to be a problem. I will look into it asap

 

Hi awais, sorry for the late response. I completely missed your post for some reason, didn't get email notification

This is a problem with how Unity deals with AssemblyDefinition files, it basically changed between two releases, which sometimes causes issuus with AHP.

See fix here: https://forum.unity.com/threads/asset-hunter-project-cleaning-tool.274173/page-7#post-5616655

 

Hi ChromazoneX

For some reason I missed your (and 2 other posts) - didn't get email notification... Sorry about that.
I have never seen that issue before, could you write me at contact@heurekagames.com then I will see if I can figure out the root of the problem (If it still exists)

 

I found a fix and will submit it for next version, untill then you can replace the old 'AH_TreeviewElement' file with this

 

Thanks for speedy responses.

 

Thanks for calling it a 'speedy' response since you originally asked the question in december
I just submitted a new version (1.3.7) which should be live in the beginning of next week after Unity has reviewed it.

 

Haha. No it is ok. I understand humans make mistake. But when you noted my message, you solved issue quickly. So I called it speedy. Cheers!

 

@KristianHJ I'm hitting the same problem as some users in this thread - all scenes in addressables and their dependencies are marked as unused. Is there a workaround for this?

 

Hi Swah. Sorry to hear you are experiencing problems. I will see if I can repro asap.

 

Ok, I found the problem. It has do do with how different unity versions deals with references in assembly definitions.
It will take some time to make a foolproof solution, but a temporary solution is:

1: Delete "AH_AssemblyDefinition" file


2: Add this line of code in beginning of "AH_SerializedBuildInfo.cs"

Code (CSharp):

1. #define ADRESSABLES_1_2_0_OR_NEWER

Now everything should work as intented.
Obviously this is not a great solution, but its quite complex to solve for all versions of Unity, so it will take a little while for me to come up with a proper fix.

Regards,
Kristian

 

Awesome, thanks @KristianHJ I'll try that in the upcoming days

 

Hello, I am having similar issues as others including an issue where with the structure of my project's scenes I cannot get it to work correctly. How can I request a refund? For example, this is what I see when attempting to use the asset: https://i.imgur.com/HiAjyMM.png

 

Hi SeanTazzik, could you tell me a little about the nature of the issues you are experiencing?
The image you posted tells you to create a build, as soon as you have done that the AHP window will be populated with your project structure, and it will tell you which files are unused.

so:
1: Open AHPRO
2: Create a build
3: Now you can delete unused files

If you have any problems after that feel free to write me at contact@heurekagames.com and I will help you out.

 

Just released version 1.3.8 which fixes an issue some of you guys have had with Addressables support. It only works for Unity versions 2019 and higher due to some limitations with Unity Assembly Definitions in 2018.

 

I purchased on the asset store with the intent of using this to clean up VRChat projects.
When using the VRChat SDK, you never really "build" your project, and in fact doing so will fail because the VRChat components arent able to be included in a standalone build. Meaning I either have to remove VRChat's SDK (breaking my project functionally) and make a build, or just not use this tool.

Is there any way to run this tool without having to make a build? I'm just looking for what I can delete from my project safely.

 

Hi WACOMalt

Sorry, AHP is getting all of its info from the build process itself

 

New release 2.0.0

Added a Dependency Graph which will allow you to inspect an asset and see its dependencies (Both to and from)


Also includes a way to get a quick overview in Project Window to see which assets has dependencies to and from (Small icons on the right hand side)


Hope you all like it,
Kristian

 

New feature in 2.1.0

Added "Find Duplicates" feature which will allow you to find any duplicate file in the project:

 

Hi Tinus. Thank you for your suggestions, they have both been implemented in v 2.1.1.
I have added options for autotriggering the re-analysis in settings (False by default)
The multiple assets selection has been vastly improved

 

Hi leniaal

This has been added to v2.1.1. You can find a toggle option in settings that will trigger auto re-analysis when project changes (Off by default)

 

Is this asset compatible with Addressables?

Also, does this work on latest alpha build currently?

 

Hi Ruchir

It does support addressables, but only in 2019 and newer.
With regards to alpha versions, It doesn't "officially" support it, but it does work just like you would expect except for a single obsolete methodcall which you can just comment out (Unless you are building a Windows Store App)

 

I changed it with this:

Code (CSharp):

1.                         textures.Add(AssetDatabase.LoadAssetAtPath<Texture2D>(PlayerSettings.WSA.GetVisualAssetsImage(PlayerSettings.WSAImageType.PackageLogo, PlayerSettings.WSAImageScale._200)));
2.  

Should I choose another resolution/scale for this btw? (Like 100 or 400)

 

I would simply delete that line as it seems like 'PlayerSettings.WSAImageType' now also includes PackageLogo, which means that the loop in line 288 will take care of adding everything.

Code (CSharp):

1. foreach (PlayerSettings.WSAImageType imageType in Enum.GetValues(typeof(PlayerSettings.WSAImageType)))
2.                        

Again, its not officially supported, but I have no doubt this will work

UPDATE: I just released v2.1.3 which has a fix for this issue

 

Hello,

before I buy I would like to ask whether or not Asset Hunter Pro also takes into account "Instantiate(myPrefab)" calls in code during run-time for unused assets.

Thanks in advance!

 

Hi Memphizzz, it does. Whether the prefab is present in scene, or spawned through script does not matter for AHP, it sees the prefab in both examples as a "used asset".

 

Please note: In version 2.2.8 AHP has moved out of the "Assets" and into the "Packages" folder to make future upgrades easier and more reliant.

Unity does however not provide any way to make this move in a good way, so I've written an custom upgrader.
If you however still get errors after upgrading to 2.2.8, please remove old version and re-import from packages manager.

Sorry if you encounter this issue, but the move to "packages" means that any future upgrades will be much easier to implement.

 

Hey Kristian!
I'm using the latest Asset Hunter Pro. I was wondering if it had the functionality to find and replace all instances of an asset with another?
Specifically, in half my project I'm using Liberation Sans in TMP. I want to use OpenSans everywhere. Is there a single button that can help me do that? Or do I have to use the dependency graph and go one by one through each scene/object/component?

 

Hi Harsh

Sorry to say, it does not have that functionality. Sounds like a valid addition though, I will add it to my backlog, but cant promise anything

 

Hello, thanks for the great asset.

I used the asset to find what's referencing some shaders that I didn't expect to be in the build. It worked perfectly using the dependency graph.

However, there are some shaders like "Legacy Shaders/Diffuse" that are built-in to the editor. I couldn't make the dependency graph show the uses of those.

I'm trying to find which used materials are using those built-in shaders. Do you have a recommendation for that?

 

Hi Meceka. Sorry, but I have immediate answer to that situation. Asset Graph show user assets (not build-in). There might be something I can to to show those, but not 100% sure. I will add your request to my backlog and see if I can figure something out

 

Thank you

 

Hi, How does webGL build? Is the window platform build used? Thanks.

 

Hi Trojant. It doesn't matter which build target you have selected. AHP hooks into the Unity build process and "remembers" which assets are used in that particular build

 

Doesn't Asset Hunter delete meta files or am I doing it wrong? When deleting empty folders all the meta files are left undeleted and unity creates these folders again. It's 2.1.0 AH on 2020.3.34f1 unity

 

Also I am having trouble with AH UI
1. It's kinda hard to delete many files in AH window. Currently I am manually searching the list of unused assets and selecting those that I can safely delete. One misclick - and all the selection is gone. It would be better to have some checkboxes next to each asset.
2. The Delete button is gone when selecting multiple folders. Why?
3. No easy way exists to know if a folder only contains unused assets. I have to check all of the assets in it, switching between unused and all lists (because you can't delete files from used/all lists) Would be great to have a special mark for that.

Am I missing some other deletion workflow? Searched the docs, seems like there's no other way. Probably it was intended to delete a single file/folder at a time but this is very uneffective as each deletion triggers 2 modal windows, asset database refresh and unused assets list rebuilding. I want first to prepare a batch of files to delete using checkboxes or maybe even a separate list of files to delete.

 

Hello,

My builds are usually 2min max. But after importing AHP I can't build at all, I even waited for 8 hours but still doesn't finish building.

In this screenshot it was at "FinishPhase" from 2min up until 8h 50m where I decided to just force close the Unity Editor.
Tried couple of times but none finished.



My project is about 100GB based on size from windows explorer.

 

Hi Romaleks. Thank you for your feedback.
1: To be honest I never thought about that particular workflow with using the search to extensively while selecting unused assets. Your selection Idea sounds reasonable, I will take that under consideration.

2: If you select folders at the same level you are able to delete. If you select a folder as well as a folder beneath it, I remove the delete button because its imposible to know what the intent here is. (Delete only 'Models', delete verything in 'PolygonNature', delete everything in 'PolygonNature' exept 'Models'? I can know, so you are not allowed to select nested folders. (This is a relatively new feature to allow for multifolder selection, so you might want to update)



3: I dont think you really need to know if folder only contains unused. The 'Delete' button only deletes unused, never used assets. If you have a usecase that requires you to have the delete button in the "All" section, please let me know.



Again, thank you very much for your feedback, it really helps me evolve AHP. I will definitely consider doing some changes regarding (1). I might also need to be clearer in the UI regarding multifolder selection + inform the user that "Delete" will ever ONLY delete unused regardless of there being used assets in folder.

 

Hi majidarif

That's obviously horrible. AHP should only kick in when the build is in fact completed so it shouldn't interfere with build times. Is there any errors in log? What happens if you remove AHP, does it return to being a 2min build.
