URP Post-Processing: Ambient Occlusion availability?

I'd love to hear an update from @Elvar_Orn (or indeed anyone) on what the plan is with the two Ambient Occlusion Pull Requests that have been sitting there for months now?

Are there breaking changes within that are too dangerous to merge right now?

 

I've tried pulling the latest commit of the SSAO branch on GitHub and set up a project in the latest Unity version. The effect works well, much better than any other (free) methods I've tried, however there are still a few bugs. Most notably, there is an issue when using the profiler which makes profiling the game impossible and I've no idea where to start to try to fix it. And I had to completely delete some 2D folders to get rid of errors. But other than that it looks good!

 

Let's hope we can use this soon!

 

I'm curious, how far is Unity going with the workflow parity here?
I saw this tweet earlier from @willgoldstone (https://twitter.com/willgoldstone/status/1268133950930780167):

I know the Volume setup is one thing that's already started with URP PP on 2019.3 but curious if Unity will "unify" the setup also on camera, lights, exposure control and sky?

The reason why I ask about this is because all those mentioned things are what currently makes it pain to runtime swap between URP and HDRP (I know this isn't officially supported atm but IMO it could be if these things were unified). I made a new prototype of this earlier this week using the wip SG stacks branch from github: With ability to use SAME shader graphs for both URP and HDRP, runtime swapping between these two feel more feasible than ever but having to deal with those previously mentioned things separately makes this still bit of a pain (every light component has URP and HDRP data components that don't play ball together, same thing with cameras).

 

We appreciate the update @Elvar_Orn, I'm very glad to hear the merges starting next week. It sounds like once Part 2 is merged (and the backports happen) then it's at a stage where it's suitable for production, performance-wise, for the Forward Renderer?

Keep pushing! I'm looking forward to testing it in my project.

 

I know this is not the right place , but there is no plan to add shadow mask to URP?

 

for AO you can use HBAO :]

 

Sure, but that is neither free nor official

 

Top notch communication from @Elvar_Orn - I wish this level of transparency and clarity was the norm.

 

It does not works with VR (Single Pass, 2019.4), so no, we can't =(

 

We tried that and got a pretty significant performance drop compared to 2019.2, so we reverted back until Unity rolls out their version.

 

I was excited to see that Pull Request Part 1 had been closed, but it's just been closed and not merged as well. I hope Part 2 is merged soon!

 

Part 1 was merged into Part 2, that's why it was closed.

 

It's been a couple of weeks, is there any update to this?

 

@Elvar_Orn was working on the pull request as recently as three hours ago!

Looks like it's been a real challenge to fix all the bugs, get through testing, and get merged. I hope it becomes available soon.

 

It was merged into master!!! https://github.com/Unity-Technologies/Graphics/pull/8#event-3511308823

 

Anyone got it working? I'm getting errors about the scripted asset importer in Unity 2020.2.

 

Yes, I'd love to hear how to get the AO features installed. Is it only available in 2020.1 right now?

How long until you can access an AO-supporting version through the package manager?

 

I can't even get it working in 2020.1 - that was my point. I'm happy to use the latest git head but I'd love to know which Unity version it's supposed to work with.

 

The pull seems to be for URP 10.0 but the “needs backporting” tags have been removed - does that mean it will be good to go on URP 9 in the next version of 2020.2?

 

As for HBAO being slower... it will be able to piggy back off this to get its own speed up.

 

So basically this will make the SSAO for URP unusable for the rest of the year before the 2020.2 releases for any serious projects who will not risk using beta or alpha versions of Unity. I understand the point in stability of older (LTS) versions of URP, but this just makes the whole package ecosystem useless because I still have to update to the last bleeding edge (and extremely buggy) Unity version to have such a standard graphical feature as SSAO.

I get that some features require newer Unity version because of the core SRP API but I believe this is not the case. We should be able to choose multiple package versions. If I feel like it I should be able to use URP 9.x.x on Unity 2019.4 LTS at my own risk, but in an official way.

 

What's the point in adding those packages if you can only fix them in new unity versions? And btw why are my changes done in the package always undo when I relaunch the project?!,like is redownloading itself if it has been modified.

Edit: Or perhaps you guys are like this: We will make "some" stuff features and the rest you have to figure out how to make it yourselfs kind of thing.

 

Are you copying the package from PackageCache to Packages folder and then editing it there?

 

Alright guys, I wonder why you do that to us.. Firstly it was announced that it'll be backported to 2019.4 and now you're saying that it won't be backported.. If you can't backport why have you announced it in the first place or vice versa if you have announced that it'll be backported why don't you do it? What kind of a policy is that?

 

SRP-api team, HDRP team, URP team, Shader Graph team, VFX Graph team, now HDRP to URP communication team

 

Thanks for the update. I'm a bit disappointed that it wont be backported, but I very much understand the reasoning. Hopefully we can upgrade to 2020.2 before we launch to take advantage of the new stuff, but I think that'll be cutting it too close to our release date. Oh well, there's always a next project!

 

Thanks for the tip. I wasn't aware that unity packages need to be moved by hand to another forlder in order to modify them.

 

Now that 2020.2 Alpha 17 has been released, has anyone giving the Ambient Occlusion a go? How does it perform/look?

 

I’m not seeing the AO show up as an option in the post processing volumes in 2020.2a17 with URP 9.x. I assume I need to get URP 10 through github instead?

 

Yes there is no other way it seems. But I do not get this, why is unity testing the feature on 2020.2 when they are about to release the 2020.1?, why not w8 a bit longer and release the 2020.2 directly?.

 

Yeah, at least backporting these to 2020.1 seems reasonable since it's still in beta.

 

What I don't get is what the feature has to do with the editor at all. I would have assumed it was purely tied to the render pipeline. The editor should be pipeline agnostic otherwise what's the point of having the pipelines as separate packages? I'm still confused by the way UT do things.

 

I have pulled the latest version of URP from Github and did some small tests with ao. At first sight, it seems to perform okay but it's a bit weird that it is not a post-processing effect but a render feature instead.

 

@Tim-C Will URP 10 be out soon on the package manager? What’s the recommended way to test this?

 

I've tried out the new SSAO and it looks promising. Seems to work in VR fairly well and on a simple scene frame rates were in the 90s.

However - there's a weird stippling effect that I couldn't eradicate. Any ideas?

See the floor on the attached image

 

Those are shadow problem, shadow bias is to low.

 

hello, I have 2020.2.0a18 installed, may I know where to get the URP v10? thanks.

 

It's not released yet. You have to use the URP version from Github: https://github.com/Unity-Technologies/Graphics

 

what version will it be fully released in?(when will you be able to get it from the package manager, not from github)

 

I suppose when the beta is out

 

I was wondering where AO is for URP and found this thread but I'm surprised.
Can URP be a universal render system without such a basic feature seen in most games outside of mobile?
I get it is using a different way of doing things (forward?) but going ahead without having this solved is puzzling.

Anyway will be good to see it in so I can play with URP as will be on previous built-in until it is officially ready.

 

hello everyone where can I download it to ambient occlusion ??

 

really would be nice have this feature for URP. it was looking good in the Github test scene. ETA on when it will be released? thanks
