I know about the notice on compatibility , but out of pure curiosity I’ve opened my big project in 2021.2 and everything seems to be working just fine. I also found in the release notes many mentions of Burst-related DOTS runtime fixes.
I am now wondering, has anyone stumbled upon any showstopper issue with DOTS on 2021.2 ? And what was it?
I have yet to test on consoles, but right now it doesn’t seem like there’s anything “not working” in Entities on 2021.2. It is in fact the smoothest Unity upgrade I did in years.
Interesting, keep us posted, I asked some time ago in Discord about higher versions but haven’t got any good answers. I witnessed the same thing in 2021.1. It was working but haven’t continued using it.
I plan to upgrade myself for some time, 2020.3 is not a good version as I’ve posted often enough now. 2021.1 and 2 have some great improvements.
Yeah was about to say i don’t think animation package works.
I’ve been using 2021.2b6 (I think i had some problems with b10 so I downgraded and haven’t bothered upgrading since) for some libraries that won’t be released for a while. Mostly because I wanted the upgraded uitoolkit runtime stuff.
Yeah so this is just a weird practice by Unity atm. They including changes to the burst package in the release notes. You’ll notice most (all?) of those fixes are in the burst changelog and exist in previous versions of Unity as well.
Tested my project in Unity 2021.2.0a12 as I don’t have any other version installed currently.
Got this error: Upgrading to 2021.2.0a11 breaks projects using Entities 0.17.0
Posted fix doesn’t work so I just uncommented this part. Compilation works then.
Everything seems to work fine in editor. Also the Build runs stable.
Who uses the animation package? lol, seriously.
I’m mainly interested in Burst, jobs and Entities. All seem to be compatible with newer Unity version. Not only is the communication a joke, even what IS communicated is one.
There’s a big difference of really unusable experimental packages being incompatible or EVERYTHING.
So, not to make it sound like I’m angry about this. I’m quite happy that I can use a newer Unity version again!
If I remember correctly, the reason why I didnt move to 2021.2 myself was that Entities and UI Toolkit (the built in one in the new stable version) does not work together. Some assembly definition issue that even plagues 2020.3 occasionally.
Burst and Jobs (and Collections) are all moving lockstep with even the Alpha build so there’s no issue there.
@tertle Can you take a look at the Entities DOTS editor and see if you can open DynamicBuffers? I can open the list of buffer items but then I can’t open buffer items itself.
Also the hover from the entities itself in the overview seems missing.
I’m using the latest version now, 2021.2.0b16.
That’s amazing guys!
Thanks for sharing these news I’m very interested in using new URP stuff which are only available in unity 2021.1+
I’ll try the new unity versions with DOTS and hope to not encounter weird bugs.
This is all great news - pls continue to report your findings - and @UnityOfficials if you plan(or what ever that plan is) to add dots support to current / future LTS unity versions only please say so - break this inexplicable silence
Does Hybrid renderer work in 2021? Last time I tried I couldn’t fix the errors or when I did nothing was rendered (it had something to do with SRP batcher)
I’ve been using Entities 0.16/0.17 + HDRP + HRv2 with Unity 2021.2.0b14 without any major issues. The biggest problem was ensuring that all shaders/materials used in subscenes are compatible with HRv2. There seems to be a bug that if any shaders are incompatible, rendering breaks completely and the entire scene becomes one giant rendering artifact. This includes the error shader, which means that my entire scene keeps blinking in and out of existence while shaders are compiling. Oh well. I can live with that for now, though.
If you need to fix your scenes, the warnings logged in the console are useful for finding offending materials.
One other issue I have is that (some? all?) lights from subscenes don’t seem to render in build - still need to investigate that though, could be my own fault.
(Not actually sure if any of those problems are 2021-specific)
@Enzi I am having the same issue with and without Odin. Some buffers are already expanded and others are not. And expand button is greyed out. @tertle Did you try with a component that has multiple fields?
in my case, I use my own hybrid renderer which is more suited to my Game Style (TOP DOWN).
Additionally, it looks like Unity is focusing more on DOTS in its hybrid renderer than actual performance.
one of the reasons I said this is:
they do Frustum Culling using DOTS (CPU), which leads to useless data transfer of survived renderers from CPU to GPU on every frame.
I read discord(unity / dots) some dev ported his project(dots) to 2022.1 and it works - i tried 2021.2 (simple urp - dots app) and it works except that when i exit unity it crashes for some reason otherwise it works fine (maybe problem is in materials as above in some posts is reported)
Half a year later, do we know if we still should stick to 2020.3 LTS when using DOTS? Our current tests show nothing wrong with using the runtimes on 2021.2, the only thing holding us back is the unfamous notice on compatibility.
We’d like to have FidelityX / DLSS, but more importantly Skinned Mesh support for VFX graph. These only are available in 2021 tech stream. Our game has been delayed to Q3-Q4 2022 and we wonder if we could safely jump to 2021.2 or not.
If you can’t say anything, when should we expect news? This year? Early next year? Still undetermined?
We just tried updating to 2021.2 on a separate copy of our project that uses a mix of classic GameObjects and Entities. Things work ok in the editor but there are AOT errors with the Entities package in the Windows build (x64, IL2CPP). I’d recommend trying to upgrade on a copy of your project. But be warned that it will most likely fail, if not in the editor then almost certainly in a build.
