Official Unity 2021 LTS Is Now Available

Needed that laugh.

Sadly I think it's just extremely poor management. A proper leadership can make an incompetent group malleable enough towards producing good work.

When they went public with stock I knew it was going to get really bad. Management's priorities are likely geared towards plans from people thinking they understand business models yet have no clue about game development or who their customers actually are.

 

I have a new problem with Unity and the attached VS debugger

Actions:
- Click in scene view
- Hold right mouse button down and move the mouse to enable the "Flythrough mode" https://docs.unity3d.com/Manual/SceneViewNavigation.html#flythrough


Without attached debugger:
-> Camera rotates around, as expected

With Visual Studio debugger attached:
-> Camera / Input seems laggy, sometimes it doesn't rotate at all and sometimes it "jumps" around a bit

Did anyone else notice this?
@sailro do you maybe have a explanation / solution?

 

Im not sure if this is a Unity 2021 or Visual Stuido 2022 problem, but did anyone else experience this issue:

The Visual Studio debugger (watch) doesn't "find" the generic argument type of a generic method when you set a breakpoint inside a generic method<T> it says "Can't find T".

Adding typeof(T) inside the watch or immediate window doesn't work either, shows the same result "Can't find T" which is nonsense, because the breakpoint is inside the generic method, so T must exist, otherwise the code wouldn't work.

The debugger will show the correct current type of T when the same code is executed inside a "normal" C# console application with a breakpoint inside the same method.

Maybe it's just a project / solution setting that was messed up during the change to Unity 2021?

The code itself still works the fine, it's only a debugger issue, so currently a workaround is to make a dummy variable inside the generic method and assign the type var dummy = typeof(T); then drag dummy variable in the watch and it will show the type. But that's a very annoying workaround.

 

Waiting for answer. It's so frustrating to debug when I can't use Unity\s methods + IEnumerate

 

I would like to raise awareness for this issue again:

https://forum.unity.com/threads/performance-drop-after-upgrading-to-2021-2-9.1262795/
https://issuetracker.unity3d.com/is...addressables-package-1-dot-19-dot-4-and-above

It is something that makes assets loading up to x4 times slower in game since Unity 2021 release. The issue has been marked as "Won't fix"! This is completely unacceptable in my opinion.

 

You guys are haliriously nuts got me bamboozled

 

Yeah honestly, generally a quick comment with the reason when something is marked "won't fix", would be appreciated - and would have avoided a confusing situation here automatically

 

Good afternoon. I would like you to pay attention to the problem:

https://issuetracker.unity3d.com/is...custom-scaling-value-is-more-than-100-percent

as for me it is not solved, because it appears to me. Perhaps it is solved, but not completely.
All other icons are fine.

 

Yaaay my first mention in this forum here and it got fixed immediately in the next release.

 

I have just today realized (due to an iOS build failing in XCode) that Unity 2021.3 LTS no longer has the "Auto Graphics API" checkbox for the iOS build target in Project Settings --> Player. The build worked fine in 2020.3.18f1, but after doing an upgrade to the latest LTS, it no longer works. I wonder why it is mentioned in the documentation and the screenshot (see here) if it isn't there anymore... One of the libraries uses OpenGLES as dependencies that now won't get added because default is only Metal and there is no possibility to change it. The only workaround for that is to manually include it in the XCode project via Frameworks and Libraries and selecting "OpenGLES.framework".

 

I can confirm that this fixed the issue, thank you very much @Alexey !

 

Can't reference AnimationClip.
I have a AnimationClipGroup, it is a ScriptableObject, it has List<NameAnimationClip> clips, NameAnimationClip has a AnimationClip field, when I add NameAnimationClip, i can't set it in UI. thanks

 

What's an LTS release? LTS is the release for creators who value maximum stability and support for their next project. This is our default release, and it's primarily recommended for creators past the preproduction phase of development who are about to lock in production on a specific version of Unity.

 

Since 2021.3.0 LTS and following releases up to 2021.3.4 i generated 3 456 567 456 Shaderfiles during build adressables and main build on HDRP. DX11 and DX12
Is there any progress?

 

Failed to build Android runtime build at Unity 2021.3.6f1. It's working properly at Unity 2021.3.5f1.

https://forum.unity.com/threads/cant-build-for-android.1306098/

 

JFYI there's another pretty major issue in 2021.3.6 related to UI: https://forum.unity.com/threads/can...broken-after-upgrade-to-unity-2021-3.1308642/

 

Consistently the worst LTS experience in recent memory. Every update fixes something critical but breaks something else just as important. They're even backporting new bugs to 2020LTS. Strongly considering downgrading to 2020.3.34LTS, if at all possible.

 

I was contemplating updating my two games from 2020 (LTS) to 2021 (LTS) but judging by these posts, maybe it's best to hold off.

Looks like 2020 is supported until mid-2023, so I'll tackle the update to 2021 later this year when it has hopefully matured.

 

Would it cost much to try out?
Keep in mind that all the users who it went flawlessly or with less than a day of amends, do not feel the urge to come here and write that

 

That's a fair point

I do agree somewhat. It may not cost money, but it's going to cost time. Time that is in short supply right now (I'm currently working on my third game, marketing my first & second and working on some website promotional articles & videos)

It'll take time to update (at-least) even one game. Time to test most \ all levels & game play modes. Time to test all key features & sub-systems. Time to-do that across all three platforms the games support. Time to work out if there are any show stopping IDE bugs that need working around or fixing.

I wouldn't normally test to that level when updating within an LTS stream, but when moving from one LTS stream to another it's a given.

In the time I've worked with Unity (only four years) I've made three moves between LTS streams. There was little negative forum feedback (from what I remember) and none of the moves coincided with production releases.

So I'm factoring all that in.

2020 is stable and supported for another year, so moving to 2021 (LTS) towards the end of the year might just save me many days of time & frustration

 

2021.3.8f1

 

Hold on busy for 3 day!

 

Is it just for me, or the last LTS (2021.3.9f1) is crashing like crazy? SThis is happening since I've upgrade from previous LTS interation. Every 30 minutes I get a crash. It's driving me nuts! LTS was supposed to be more reliable

 

I am getting immediate and persistent crash while entering play mode of a bigger scene of our project since upgrading from 2021.3.9 to 2021.3.11. Never had a crash before with that scene. Lots of usage of compute shaders, if this matters. Filed a bug report: IN-18255

Message in Editor log:
Assertion failed on expression: 'm_BuffersToBind[shaderType][bind].buffer == NULL'
Crash!!!

Update: To get extra sure, downgrading to 2021.3.9 -> no crash. So this seems to be caused by changes of either 2021.3.10 or 2021.3.11.

Update2: Saw some traces of an older bug on the internet, which talks about using line renderer producing the message above. As a hint, I am using the new hair system which also uses line renderer. This might or might not be related.

 

can you please add something to the auto-updates screen
when I click download new version can you warn me that if I download that my project will not work in it?

 

My bug report mentioned above was closed with the comment responded. The response was a generic list of things like “update gpu drivers” etc.
but as mentioned, crash only occurs with 2021.3.11. Downgrading to 2021.3.9 is resolving the issue. So I highly doubt that it is a driver issue on my end.

 

Hello,

Is there any plans to add fsr 2.1 support for 2021.3 hdrp?

Thanks

 

The Release Notes of 2021.3.12 has a lots of duplicated notes coming from Release Notes of 2021.3.11

• Editor: Fixed case where Editor would crash when a selected renderer was deleted. (UUM-3249)
• Editor: Fixed crash when opening scenes in builds that had missing Prefab sources. (UUM-2546)
• Editor: Fixed dragging prefab with ctrl on linux. (UUM-1601)
• Editor: Fixed inspector and documentation to reflect intended behavior. (UUM-2392)
• Editor: Fixed SceneVisibilityManager exceptions when using shortcuts with no Hierarchy window. (1425103)
• Editor: Fixed the "Auto-hide gizmos" preference in the Scene View page to persist value when reopening the editor. (UUM-7848)

What's wrong ?

 

They fix it three times before it's half fixed apparently.

 

in 2021.3.13 i changed the static options on an object to disable occluder and some other stuff for a window, and I've been caught on this for 10 20 minutes.

This is the last section of the unity log that seems relevant. I haven't killed unity yet cause I'm not 100% sure when I last saved.

Edit: After killing Unity there is no further logs.

 

I'm having a problem where my realtime reflection probes are rendering completely black, all of them.



This persists through reimport and reload. And i have no idea whats causing it all i did was bake lights. and they worked earlier.

Baking them doesn't work either.

EDIT: turns out this is related to an SSGI asset i was testing.

 

I am consistently having this problem randomly. it's never a minute hold up, it's basically a crash. it's in 2021.3.14 too.

I could click literally anything, and basically unity is in a soft crash. I don't remember having this problem in Unity 2021.3.5.

Like i pretty much have to kill and reload unity every 30 minutes to an hour. This is not a hardware issue, I have EVERY hardware advantage that should make anything take this long impossible.

I've done full reimports, and there's no consistent pattern.



I haven't taken the time to see if it ever stops doing this.

 

Hi there! I am transferring a project from 2020 LTS to 2021 LTS. I see a picture in the log on startup. Basically everything is working as before. Is it worth bothering with these errors?

 

4 hours, I did a little work this morning, this popped up as i was simply rotating the camera so i decided to just leave it while I do some black friday shopping.

Came home, still there.



Again the log doesn't give any valuable information.

here's a download of it.
https://www.dropbox.com/s/6dl6tau8zst98u1/Editor.log?dl=0

 

Looked at that 68 meg log. Basically it is saying "Go Back To Previous Unity Versions if you want to be a creator who values maximum stability and support for their next project." !!

 

I swear whatever this is it's on a timer, if I leave unity open in the background for like an hour I'm guaranteed to get the problem after a click or two.

I know this has been a problem for a while but not to this degree.

 

Downgraded to 2021.3.12 and got a variant of the problem. I'll keep downgrading by version until the problem goes away I guess?

 

Another way to go about it would be to strip the project step by step until you find the culprit. Or do you happen to have another project where this occurs and can compare whether you have any plugins or own packages in common?

 

2021.3.14f1 is crashing during ComputeShader compilation when creating an empty HDRP project. Manually reimporting all ComputeShader works.
Crash dump attached.

Are you aware of this issue?

So it turns out my issues were likely related to some kind of corrupted data that couldn't be fixed with Reimport. I redownloaded my entire project from the repo and the issue is gone.

I don't know how or what corrupted data could have caused such a thing, but that seems to be the problem. It had nothing to do with the unity install itself.

I think there should be a max time for that window to be up in case there's a failure like this. Cause clearly it's not capable of identifying the problem.

 

Data corruption seems to be the theme of this LTS release cycle from my anecdotal exprience.

 

What files do you have in the gitignore?
The library directory, I assume?

 

I updated from 2021.3.9f1 to 2021.3.14f1. A few minutes after starting the editor -- I don't see any obvious trigger, although I have been working in the VFX and shader graphs a lot -- it slows to a crawl in edit mode.



Methinks it's only supposed to be doing this once, not every frame

I found someone on Reddit talking about this about a month ago. We're both using M1 Macbooks, so that sounds like a common cause. I'm not seeing any (relevant) errors in the console.

I'm going to downgrade to 9f1 and see if the issue goes away.

EDIT: the upgrade wasn't it! It might be something to do with visual effects instead, given that I just started using those in the project today. Will keep poking around...

 

yeah the library is not on the repo, i think i use a mostly standard gitnore.

 

I was seeing some strange behavior in the editor too, I haven't tested the game again but i was getting a ton of editor loop.

Perhaps your problem is similar to mine?

 

Still crashes with 2021.3.15f1 when creating an empty HDRP project.
