HBAO Horizon Based Ambient Occlusion

Hello,

We worked on a PostFX named HBAO for our upcoming game "Edge Of Eternity", we wanted to known if some people are interested in this asset if we put it on the asset store,

HBAO is another method for ambient occlusion, it play nicer with depth / fog and give a more natural feeling than Unity SSAO.

Settings are highly customizable like unity SSAO !

(Environement using Medieval Environment from Mickael.O, Character from our game "Edge of Eternity")

Comparative :

No Ambient Occlusion


Unity Screen Space Ambient Occlusion


Unity Screen Space Ambient Obscurance


And Finally our HBAO


We'd like to hear any feedbacks !

 

I was waiting for HBAO since Unitys Butterfly Demo

If it's just 5$, I'll buy two !

 

It looks interesting, but does it have the same issues as SSAO with transparency and such? Also, using SSAO with vegetation (grass) on the ground often leaves blobs showing through the terrain.

 

Very interesting.
What's its performance comparing with the different solutions for ambient occlusion?
Can you also use other type of scenery to showcase the effect? It's a little difficult to see the differences between the solutions.

 

yup ill try it

 

Maybe a little webplayer to show the differences ?

 

Can you show the AO buffer comparison (you know that black and white ao texture )? or maybe exagerate the AO intensity.
Really sorry but i can't see the difference (or maybe it just my eyes )

 

That would be perfect.

 

If the framerate is better than Unity SSAO why not? 5$ is not a big risk.

 

Looks good! And yes, for a fiver I'd take it

 

Webplayer here :

Thank you for the webplayer, but it lacks the framerate .

 

Purchase for me, its not perfect becouse shadow of object can still be seen in fog bit wierd, but as long as its better than normal AO its buy, for 5 bucks especially.

 

I've set the fog really near to show the effect, in reality it's kinda rare that you set the fog so near, and even if i'll add a Z cut value

 

We did a major optimization and included an ultra fast version of the shader (+10 FPS) but with less precision, it now have correct performance with improved visual quality compared to Unity SSAO. It mean that we will release it very soon .

 

Being very hopeful here, but will it work on mobile? I mean in some practical way.. if it does work, then can you let us have a sample apk with FPS indicator?

 

This is a nice effect. I couldn't really tell the differences in the screenshots you posted, but I found a paper its based on that has some nice B&W AO-only shots. For anyone interested it is at http://developer.download.nvidia.com/presentations/2008/SIGGRAPH/HBAO_SIG08b.pdf

 

very interesting and the price is very cool. but on the pictures you can see the difference bad. can you possibly show in a simpler scene?

 

@Castor76 : It should work on mobile but honestly any image effect is a performance killer on mobile it doesn't worth it with GLES2 (GLES3 support it better)

I've updated the Webplayer, now there is an option to show the AO pass in B&W, i've added the ZClip option too, i will submit it to AS very soon, performances are now great .

 

Is ZClip fancy talk for a distance fadeout setting?

 

Yes, but it's not "fade" it's clip AO or not AO

 

Looks interesting! Is it commited to the store?

 

Really interested in this asset once it gets released. Does it work with Deferred Rendering?

 

I'm interested!

 

What about FPS? Is it less FPS hungry that Unity SSAO and Unity SSAobscurance? Would buy it then.

 

Sorry didn't have many time to update, when i have some free time i'll create a new scene more lightweight to demonstrate.

 

This looks and sounds great.
If it is really less fps hungry than Unity's built in SSAO effect, I'm willing to pay more than 5

 

Does this only work with geometry baked into the scene, or will it also work dynamically-instantiated props?

 

It work with everything that write into depth buffer ^^ (everything, only alpha blended shader or zwrite off are not targeted)

 

When it is released? I would buy it.

 

is this still coming, cause if it's good, i'll buy it for sure, ssao from unity is really bad with fog.

 

Definately interested in this.
If you guys release this HBAO screen effect on the asset store, what prices can I expect?

 

What's the status on this?

 

Has this been released yet? We're waiting for it.!

Hi, Great Effect man, I'm wondering if you can help me. I'm trying to set in code so I can change settings during runtime, I tried the following code but says about storing some value.

hbao is set to reference HBAO script.

Code (CSharp):

1. public void bSetHBAOQuality ()
2.         {
3.             switch (Mathf.RoundToInt (HBAOQualitySlider.value)) {
4.             case 0:
5.                 hbao.presets.preset = HBAO.Preset.FastestPerformance;
6.                 HBAOQualityText.text = ("Fastest Performance");
7.                 PlayButtonFx (buttonClickFx, buttonFxVol);
8.                 break;
9.             case 1:
10.                 hbao.presets.preset = HBAO.Preset.FastPerformance;
11.                 HBAOQualityText.text = ("Fast Performance");
12.                 PlayButtonFx (buttonClickFx, buttonFxVol);
13.                 break;
14.             case 2:
15.                 hbao.presets.preset = HBAO.Preset.Normal;
16.                 HBAOQualityText.text = ("Normal");
17.                 PlayButtonFx (buttonClickFx, buttonFxVol);
18.                 break;
19.             case 3:
20.                 hbao.presets.preset = HBAO.Preset.HighQuality;
21.                 HBAOQualityText.text = ("High Quality");
22.                 PlayButtonFx (buttonClickFx, buttonFxVol);
23.                 break;
24.             case 4:
25.                 hbao.presets.preset = HBAO.Preset.HighestQuality;
26.                 HBAOQualityText.text = ("Highest Quality");
27.                 PlayButtonFx (buttonClickFx, buttonFxVol);
28.                 break;
29.             }
30.         }
