Urgent - Editor hang - Endlessly looping on hashing assets 2019.2.3

Hi there,

We urgently need to get to the bottom of a Unity editor hang problem. We have tried everything to figure out why this is happening but we have nothing to go off. We've recently updated to 2019.2.3 from 2019.1.8, we're using LWRP 6.9.1. We start running the game, we think once we hit stop or perhaps unload certain scenes then eventually this leads to a hang where the editor freezes. The Editor log is showing this logging out 100's of times:

It will do this for a few minutes until eventually crashes the editor. The stack trace looks completely useless. But I'll and get something up here. We've tried turning off cache server but then it takes even longer until it crashes. We've tried clearing cache server cache, then close Unity, deleting the Library folder to force a reimport, but it hasn't changed the outcome.

We're desperate to fix this we have a huge deadline going on and don't know what to do. I've sent a request for premium support. I think a bug fix report is not going to be possible, we can't send a 16GB project and it's not something we can isolate in a small empty project. We need a workaround asap.

Thanks,

Jason

 

Here's the log that it outputs after doing this Hashing assets 100's of times:

Hi there,

Is anyone at Unity able to help us with any kind of suggestion on what to do? Is there something else we should be doing to help this along? We've been paying pro customers of Unity for 6 years and if ever there was a time where we need your help is now. We are in urgent need of help to resolve this issue. I've not heard back from requests to pay for premium support either.

Thanks,

Jason

 

Thanks... we've tried upgrading / downgrading between LWRP/Core/SG from 6.9.1 to 6.9.0 and back again, no difference. We've cleared the cache server and Library/obj folders more times than I can count. I appreciate the suggestions though, we've tried everything we can think of to isolate the issue.

 

Re: the issue above. It's not realllly something that quite fits with out scenario. We do use PlayerPrefs.DeleteAll() regularly to clear user data. But the hang is happening most of the time simply by doing these steps:
- editor is opened fresh
- hit play
- stop the player
- some arbitrary time later the hang happens, most of the time when hitting play a second time though it hurries the hang along to occur sooner

It's like some kind of clean up issue or something that's stuck on removing itself after the app has run. We don't seem to have any runtime issues for compiled builds, only when hitting play in the editor.

 

Thanks we'll have to do that, it's a bit of a concern for us posting up sensitive project data, we totally trust Unity. But it's an obligation contractually we have to consider to minimise risk. So anyway, we'll strip it back and then get something submitted, it's a really hard one to replicate predictably. Sometimes you'll run the editor 12 times and no hangs, and then a string of hangs 20 times in a row, inconsistent hard to replicate bugs are .. the ... worst.

re: which scenes/assets, it's almost indiscriminate and no decent patterns. Just run the app. Maybe it hangs, maybe it doesn't ie. doesn't seem to matter if I load up a huge scene with hundreds of materials or intro scene with a couple, it could run ok or it could hang. Not much to go on. Thanks again for the reply, sorry for being dramatic with the reach out, but we're quite stressed about all of this and desperate to fix this, huge deadlines looming and all.

We'll get a bug report going, request the cloud storage for the report and post up an id here as soon as we can, thanks.

 

@jason_yak Any updates on what the cause? Or have a bug report? We're facing the same issue in Unity 2019.2.5.

 

For everyone else, we found that deleting this folder prevents the hashing bug:
"SRP/com.unity.render-pipelines.lightweight/Editor"

@Domas_L Someone at Unity should probably look at that.

 

It's 100% repro for anyone with that folder in our project. We're using Unity 2019.2.5f1 on iOS/Android platforms with LWRP 6.10.0 on Macs and Windows PCs.

With these folders in our SRP folder:


When we delete it, it prevents the issue, so that's a fine solution for us. Does SRP/LWRP play nicely with the AssetPostprocessor pipeline? Because we have a custom texture postprocessor in our project.

 

@Domas_L It's what we suspected.

The file "SRP/com.unity.render-pipelines.lightweight/Editor/2D/MaterialPostprocessor.cs" is causing the behavior that @jason_yak is seeing.

It's causing the materials in our project to reimport and re-hash continually. We don't even use 2D in our project. Why would this be doing that?

 

Hi there, it's been quite some time since we reported this issue and it's still plaguing us daily with hangs. I've only just been able to corner the issue and I'm in the process of submitting a bug report, I can replicate this issue now consistently in 2019.2.12 using LWRP 6.9.1 and 6.9.2, and 2019.3.0b11 with LWRP 7.1.1 and 7.1.5, submitted one for 2019.2.12 and one for the beta. I'll post the id up here shortly. Here are the details on how to reproduce it:

1. What happened
When calling PlayerPrefs.DeleteAll() while the editor is open whether it is called at runtime or by an editor script while the game is not running causes the editor to hang the next time we hit play. Looking at the editor log we can see that it's reimporting and hashing all project assets. Eventually the hang will end, but as you'd imagine the larger the project the worse the hang, and in our main projects means it's stuck for 10-20 minutes each time. I can confirm that this issue only occurs when using LWRP but has been happening for us since we upgraded to 2019.2.x many months ago and is still occurring in 2019.2.12 using LWRP 6.9.1 and 6.9.2, and even in the latest beta 2019.3.0b11 with LWRP 7.1.1 and 7.1.5. The moment we remove the LWRP package the issue stops occurring.

2. How we can reproduce it using the example you attached
- Create a new empty 3d project
- Add in our editor script ResetUserPrefs which just allows PlayerPrefs.DeleteAll() to be triggered in an editor menu option.
- Create a new material and assign it the basic Unlit > Color shader, this step may not be important but we did this to minimise complexity.
- Duplicate the material, select all materials, duplicate again, repeat until you have about 300+ materials in the project ie. so you can see the hang occur while the editor reimports these assets.
- Hit play as a control test to see that the scene runs fine and doesn't hang, then stop.
- Trigger the Test > Reset Player Prefs menu test script that calls PlayerPrefs.DeleteAll()
- Hit play and you'll get the import hang I've described, which in our actual production projects hangs for a very long time.

ie. clearing the Library doesn't help in our older projects, we get this issue consistently in a brand new empty project.

 

I should add that, if you remove LWRP and repeat the test, triggering the DeleteAll the hang does not occur.

 

Issue ID for our 2019.2.12 bug report: 1199695

 

and a second bug report submitted from 2019.3.0b11: 1199704, wasn't sure if that was necessary to do both, but thought it might hit different teams if I submitted against both versions.

 

Hi @Domas_L just wondering if someone is looking into the bug reports, it'd just be great to know if the wheels are turning on a fix? thanks

 

Following up that I just got confirmation that the issue has been reproduced by Unity QA and sent along for resolution... that's great news =)

 

Hi there, I spotted someone elses comment in the bug tracker, which is:

We were also running into that issue. I checked and it seems unity is now writing their own keys to PlayerPrefs. One of them contains the version of LWRP. If that's not there I assume unity triggers a reimport. I really think unity should not be writing anything into PlayerPrefs, this should be purely for game specific data.

Would a workaround be that if we knew the LWRP data keys we could pull this data out temporarily, delete all prefs and reinstate the data? Does anyone know how to find out what data is in the player prefs on a mac to see what the keys would be? the playerprefs api requires that you know what the dictionary keys are.

 

@Domas_L any updates to share on this issue? It's been over 6 months that we are unable to test our game in the editor and having a huge impact on our team, and ability to work efficiently.

 

@jason_yak my temporary workaround has been to make LWRP/URP a local package and comment out the block of code in MaterialPostprocessor.cs that reimports everything (ReimportAllMaterials). We were only experiencing this bug in the form of our Unity cloud builds more than doubling in length, but I imagine it would work for your use case too.

Makes it a bit more painful to update the RP, and you might want to let run the reimporter once whenever you update (not sure of the side effects of commenting out). It's still been worth it for the faster builds for us. Hopefully that's able to help you in the meantime.

 

@awallick-sd thank you so much, by pointing me to the code this lead to me finding a different solution. Instead of copying LWRP package I simply store the lwrp string and reapply it before and after running a DeleteAll command before the preprocessor gets a chance to know it's missing.

var lwrpVersion = PlayerPrefs.GetString( "LWRP-material-upgrader" );
PlayerPrefs.DeleteAll();
PlayerPrefs.SetString( "LWRP-material-upgrader", lwrpVersion );

(this works for LWRP v6.9.1 at least)

 

@jason_yak Glad that helped!! I think your solution definitely makes more sense and is much simpler in your use case. I couldn't find a way to set that PlayerPref early enough in the cloud build process to avoid the full reimport back when I was figuring out a workaround, so I think I'm stuck with the local package for now. Hopefully it's fixed soon and we don't have to do either
