SSAO Pro - High Quality Screen-Space Ambient Occlusion

The test project was in 5.2.2p3, upgraded to 5.3.6, then to 5.4.0p3, and finally to 5.4.0p4. I don't know if it happened on 5.4.0p3.

 

Any chance of adding support for Single Pass Stereo rendering in VR? Also performance in general is pretty poor in VR, it seems all SSAO solutions suffer from this, which is a shame because it really helps increase immersion inside the headset.

 

True, all effects are a little more expensive in VR, but with AO in particular it's proving to be a real struggle to find one that looks good and doesn't crush the framerate

 

Just trying to run the demo scene in Unity 5.4.1f1
Graphics card NVidia 970
Error Message:

Unsupported shader (SSAO).
UnityEngine.Debug:LogWarning(Object)
SSAOPro:OnEnable() (at Assets/SSAO Pro/Scripts/SSAOPro.cs:148)
UnityEditor.DockArea:OnGUI()​

 

Getting a similar issue here with a series or errors
Shader V2 (on reimport)
Error:

Followed by a series of these errors referencing different lines:

Shader V1 also contains this error:

Any help please, where you able to fix this before? We have tried multiple re-imports but no joy.

We're using Unity 5.3.6p2 (64bit)

 

Hi yes I can confirm that the file exists and is in the Resources folder next the shader. I can fix the missing cginc file by adding the full file path in the shader but im still getting this error.

*update*
For now we have patched this by adding the full .cginc file path to all references in the both shaders and commented out the bilateral smoothing pass in the shader (pass No. 6)

also I have tried this with the latest version of Unity but still get the same issue. is anyone else seeing this or is a local issue to us?

 

Our target platform is Android but I have also tried it with PC Standalone. Maybe this issue is our end I'll have a deeper look into it and let you know if I find anything of interest.

thanks for your support

 

On the issue of performance drops when too close to a wall or big object (didn't think cache misses would be so expensive, the frame time of the SSAO goes from 10-15% to around 50-60%!), we've done the following change in the shader:

Code (csharp):

1.  
2. half radius = clamp(_SampleRadius / eyeDepth, 0.005, 0.05);
3.  

If I'm correct, this clamps the sample distance to 5% of the screen, which is enough to avoid performance drops on 1080p and there's no noticeable difference on our game.

 

Hi,

I'm using 5.4.3 and can't get this to work with single pass stereo. I get a bunch of messages in the console:
https://i.gyazo.com/aec7fb9108485dd0b5c255b9848e6852.png

All I'm doing is adding SSAO Pro to a camera in an basically empty scene with single pass stereo enabled. (Deferred, linear.)

 

I'm using the latest available package in the asset store (2.1).

 

Thanks.

While you're at it... I'm not sure if it's fixable, but another issue is that it doesn't seem like the new post processing effects play nicely with ssao pro. It's as if the AO gets inverted or something.

 

What SunnySunshine said! I included a needlessly large shot of it, hopefully it helps! Unity Version 5.5.0 b11

 

I'm not sure about his case, but just to show you the problem I'm having.

Here's what it looks like with both enabled:


If you disable post processing, it still shows shadows in a weird fashion:


If you disable both behaviours and then just enable ssao pro, then it displays correctly:


(And just for reference, this is what it looks like w/o anything.)

My settings

 

Negative, I'm using deferred and have MSAA off all the way.

I am using the DirectX11 pipeline though. Pretty much identical to SunnySunshine's settings.

 

Unity 5.5 final just released. I tried out SSAO Pro with single pass stereo rendering and am still getting a double vision issue, so the plugin is not compatible with it

I'm using it in an empty scene using the SteamVR plugin

 

I want to make a request to bring back the Bilateral blur filter to the latest version of the plugin.

It may not look as smooth or pretty as the other ones, but at the very least it doesn't show seams like the other two, which is a huge plus for us (our game is dark so any seam is very noticeable).

I always have to edit the updated versions to add the old filter, so it would be better if we didn't need to.

As a quick sample of what I'm telling:

No Blur:


Bilateral blur:


HQ Bilateral and Gaussian (notice the seams in the right arm):



The smoother the blur, the more evident these seams are.

 

Reporting back, your fix worked, no more conflict on my end with the post processing chain. Thanks!

 

The fix appears to work in the editor, but when I go to make a build, i still get a weird flickering effect. I appreciate that without the hardware this might be hard for you to solve. Let me know if there is a way I can help you with this

 

Nice asset. Just discovered it.

 

I'm having trouble with SSAO Pro and Speedtree, see screenshot. This is in forward rendering. I went to the page linked from a reply about a similar issue on the previous page of this thread, but it didn't seem to apply. Is there a way to get SSAO Pro and Speedtree to work well together?

 

Can not work with ValveCamera of "TheLabRenderer", link: http://u3d.as/tNq
Please fix.

 

Hello I would like to ask you if it is possible to attach ssao script somehow to work with camera.render(); function. It is necessary that I am baking objects into textures and then I get absolutely different results. And found that results are in ssao... Thanks for response in advance

 

@Chman I'm getting these errors when doing a Standalone build:

Do you know what would be causing these errors?

 

Is it supposed to work with GPU instanced meshes? Using https://docs.unity3d.com/ScriptReference/Graphics.DrawMeshInstanced.html



The AO effects aren't applied to these meshes and the AO effects for objects behind them are rendered on top of the instanced meshes. Possibly related to this Unity bug? http://answers.unity3d.com/questions/1288036/graphicsdrawmeshinstanced-does-not-receive-imageef.html

 

Hi,
I'm having issue with the asset when I build to android. It's working fine in the editor, but on device it looks like this:



Thanks!

 

Hiya -
SSAO Pro worked beautifully until we tried adding decals. When the decal system (store link) and SSAO Pro are both enabled, it appears as though the AO reads from one of the color buffers instead (note the presence of the shadow in the AO buffer with decals enabled).

Any idea why this would be happening? Any guesses would be great. Thanks!

Spoiler: Decals Disabled

Spoiler: Decals Enabled

 

surely is. As it reads depths from objects behind I had a problems with depth too on two sided materials, but author helped me to solve. No clue about gpu meshes thought...

 

Hi! I've been using SSAO Pro on our game project for a while now, and it has worked really well. It seems however, to be having some issues since we updated to 5.5.0f3. It is no longer shading in corners of geo as it should but is covering the most of the screen and shading objects in more of a 3D way. Are you aware of any known issues with the newest version of Unity?

 

I had same issue after upgrading unity... but found I did not have actual version of SSAO - it fixed.

 

Is there any way to ignore certain objects (or a full layer) when dealing with the AO?

It's pretty hard to blend the grass with the terrain in a nice way.

 

Would this work on objects with transparent materials ?

 

Hey I have a question. how could i use it two deferred cameras as example for a FPS.
The SSAO doesn't work when i want to render the background (the first renderized Camera).

More info using 2 deferred cameras:
If SSAO is on Camera layer 0 the effect doesn't work.
If SSAO is on Camera layer 1 the effect just work to what is rendered in the Camera.

 

Just updated to 5.6f3 Got this error. Any tips?

We submitted some bugs around multi-camera and deferred rendering a while ago. They were eventually closed as duplicates a while ago, but the duplicate issue appears to still be open. This might be related to these SSAO Pro image effects problems.

Our closed issue: #835332 "Deferred rendering path does not support 'Clear Flags: Don't Clear" - showed rendering problems compositing multiple deferred cameras with no effects being used.

Active issue: https://issuetracker.unity3d.com/is...s-of-two-cameras-is-rendered-completely-white

Edit: I can confirm that our original issue still isn't working in Unity 5.6 - compositing multiple deferred cameras does not work.

 

Hi greg,
would you so kind and query me the example "Deferred.zip" from the bug report you have posted?
I really like to have look on this and compare it with my settings.
Thank you.

 

Sure - have pm'd you the link Let me know how you get on with it.

 

I'm having some problems in unity 5.6 with SSAO Pro. My setup is this:

SteamVR application (Forward Rendering, Single and Multi Pass Stereo Rendering)

Secondary camera that follows the user's movements but renders to the main display of the computer, rather than VR

With SSAO Pro disabled, the secondary camera seems to render normally.

With it enabled, the image is inverted, but the SSAO effect is in the correct orientation

Here is a screenshot:

http://puu.sh/vbqSw/3c159c2043.jpg

Any idea what might cause this? Thanks!

 

We have this exact same problem on Unity 5.6.0f3 with SSAO Pro 2.1.1, but only using one camera that switches between normal and VR with a key on the keyboard.

The game starts in normal mode and everything is fine. We switch to VR and everything is still fine. When we switch back to normal however, the camera image is inverted and SSAO is in correct orientation. Everytime we make the switch after that, VR is fine, normal is incorrect. For now we are thinking of compiling two separate versions: One for normal use and one for VR use.

 

Hi,
I have an issue where after certain amount of distance with a camera i get these tearing black lines
Image 1 - is where camera is set to x 0 y 0 z 1000
Image 2 - is where camera is set to x 0 y 0 z 0
Iam using Unity 5.6.0
