URP Post-Processing: Ambient Occlusion availability?

It has already been released. It’s in preview though, so not recommended unless you really need to use this now over a 3rd party package like HBAO.

 

Is HBAO an asset on store ?

 

Yes.

But if you don't need AO right now, you can wait few weeks, use the official SSAO for URP and save a few bucks.

 

thanks for the information.

 

Sorry I'm a bit confused trying to follow this thread - does this mean that there will never be an official AO solution for 2019.4 using URP?

 

Correct.

 

Anyone know how to get the AO to work in combination with the official URP first person rendering setup? No AO is applied to the first person objects. HBAO works fine with it.

Unity 2020.2.0b2
URP 10.0.0-preview.26.

 

Installed unity 2020.2.0b2 and have the SSAO, but can't see it take effect. Anybody got it working in this unity version
@Tim-C and @elvar_orm

 

@Elvar_Orn When are you adding AO color?

 

If you can also add color bleed (pseudo GI) that'd be awesome.
How are performance in URP deferred? I think you guys pulled it out of github and since I'm still profiling for mobile I'd like to know if I should postpone a few conversions.

 

Sorry I should have been more clear. The AO does work. However it does not appear on the first person models (e.g. guns) as seen in your own screenshots. I need the AO to apply to both the environment and the first person models.

 

Have you tried it with camera stacking?

 

Hi all, been searching high and low to find this discussion on here. Have converted a mobile project to URP and wanted to use AO. Saw in the docs that v10 of URP only works with Unity 2020.2 beta so installed the beta. Sorry if it's mentioned somewhere else but just can't see or understand how to install URP 10 anywhere. It's not showing up in package manager, and if it's in a repo somewhere how do I import that package? There seems to be bits everywhere, I appreciate this is in development still, lots of hard work going in to this, but there doesn't seem to be any clear instructions on how to use the latest stuff.
Any help would be massively appreciated as I want to try out URP 10 (including AO) with 2020.2 beta.

 

It's a bit hidden. You need to go to the package manager and activate preview packages there. Once preview is activated, there will be more version options for official modules like URP. Search inside advanced.

 

THANK YOU!!!!! THERE WE GO, ah man that was really hidden!



Achievement unlocked!

 

^ how is URP speed wise?

 

I too would love to see some Ambient Occlusion performance results from anyone developing with URP on the 2020.2 beta. Some with AO/without AO screenshots and the difference in what the profiler shows would be great.

 

^ do it

 

I'm not a pro in unity or something like that, but I made a comparison:

2020.2.0b5 - AO On


2020.2.0b5 - AO Off


2020.1.7f1 - AO On


2020.1.7f1 - AO Off


It's a Random Level generated game, so the number of entities may vary, but in 2020.1.7f1 there are more entities than 2020.20b5 and AO didn't make any impact in the FPS. I don't know how AO works, but in URP looks like they created meshes for the AO effect, and it's not a post-processing effect.

 

I had similar experience with 2020.2.0b5. AO consumed a very extrange amount of FPS (default scene for URP).
I didn't tested AO in 2020.1.7f1 yet. Seems promising.

 

how did you get AO in 2020.1?

 

Sorry, I forget to mention that AO is from Post Processing without the URP installed
(Sadly this don't work with URP)

2020.2.0b5 = With URP + Native AO from URP
2020.1.7f1 = Without URP + Native PP+AO from Unity

 

ah yeah 100fps vs 60 sounds in line with the party
the unity AO is, errr how do you say, good for amateur night, but it's more like 10ms not 3x so I think you have a bug somewhere, cpu at 34ms sounds like a nullref.

 

So far for the URP, I just followed some tutorials to make the import, convert materials, etc. I didn't get deep in URP because there's not an official AO. My first impression of the URP was very good, improved the FPS and the only problem (Aside from AO) was the shadow with a hard edge and a scene little too dark. But for some reason when I add AO, the FPS drops a lot, I'll wait for the official release of AO to dig into the URP, maybe be a bug in my game, maybe an improvement to do in URP, I have hopes for URP.

 

Is there an ETA on AO working in deferred?

 

I've just found, in unity 2020.1 (I don't remember if it was there before) there is an ambient occlusion option and it works with universal RP!

 

Hej, we reverted back to unity 2020.1. we are developing an oculus quest MVP and wanted to try out some optimised Ambient occlusion. Thats why we tried this.

 

How? The Unity developer working on this features said it wont work before 2020.2?

 

i've been messing around with the new SSAO in URP. Pretty nice but, it doesn't work on emissive materials AKA toon shaders with the custom node for custom lighting. SSAO is a must when doing toon shading and its kinda bad that it only works on regular shaders.

 

This makes sense if you're doing custom lighting, you'd now have to incorporate the occlusion factor as well which is usually multiplying your base color by it.

You can sample the generated occlusion texture like so:

Code (CSharp):

1.  
2. float2 normalizedScreenSpaceUV = GetNormalizedScreenSpaceUV(<clip space position>);
3. AmbientOcclusionFactor aoFactor = GetScreenSpaceAmbientOcclusion(normalizedScreenSpaceUV);
4.  
5. mainLight.color *= aoFactor.directAmbientOcclusion;
6. albedo *= aoFactor.indirectAmbientOcclusion;

 

I'm trying to enable the SSAO Render Feature as detailed here but have no option to enable URP 10 in the Package Manager. Preview packages are enabled, only have options up to v9 though. I'm using 2020.1, is this only available in 2020.2?

 

Yes.
URP Screen-Space Ambient Occlusion is only available in Unity version 2020.2 or higher.

 

Got it, thank you.

My use case for this is the Oculus Quest... does it perform well enough to use on that platform or am I chasing a red herring? It would be pain to migrate to 2020.2 right now, so if it's not usable for my needs anyway, I won't bother.

 

Unfortunately, I am yet to use the feature either. (I just know that it's a 2020.2+ exclusive).

I have heard though, that the URP SSAO is pretty performant (performant enough to match other SSAO options). If it's a huge pain to test it out, however, only advice I can give is to wait a few more weeks / months so 2020.2 is a bit more stable, then migrate when you're ready.

 

Found the SSAO of URP is working incorrectly in the Scene View/Editor window. A similar case has been filed by someone.
The gameplay camera view is correct though.

Thanks for your prompt response!
Believe is this setting, right?

 

While you're here, can you take a look at that bug with overlay cameras? Depth textures don't get rendered.

Thanks Elvar.

 

Hey thanks a lot! i'll try it out as soon as i'm off work. it looks neat!

 

Well! it did work! i had to alter it since i<m using a custom node in shadergraph and thers a lot of things that i can get precalculated. but you lauched me in the right direction! so here is the final code :

Code (CSharp):

1.  
2. AO = GetScreenSpaceAmbientOcclusion(ScreenPosition).indirectAmbientOcclusion;

 

I did something like this in my toon shader, but it does not work.
Do you know by chance how it should be done in unlit shader graph?

// edit: Obviously it does not work in unlit,... so it can't be done using depth normals.

 

you can do it easily using this method for the renderer: https://docs.unity3d.com/Packages/c...iversal@10.0/manual/post-processing-ssao.html
