SSAO Pro - High Quality Screen-Space Ambient Occlusion

I'm looking for an Ambient Occlusion solution that allows us to exclude objects/layers. I know you mentioned you're looking into it on page 1. Is that still the case?

Thank you

 

I've been using SSAOPro since 1.1 release and having my project upgraded to Unity 5, it's nice to see it keeps up still. Most people say that SSAO is an unnecessary process, adding very few details only 5% of the players will realize, but I disagree, it adds a lot, and for some scenes it does better work than enlighten.
So, congrats

I have a question that is not directly relevant, but is shader keyword count important? I mean is it performance wise effective or what?

 

Oh, I see, thanks. I'm not good with understanding of graphic pipelines, but the document explains a lot. I'm also using Alloy and couple of other assets that will fill up the keyword limit. Though my project is stable at the moment, I can imagine how can that be a pain for larger projects.

 

Hi, I noticed that when I updated to the latest version (1.4), it seems to have removed the 'noise' texture that was in 1.3 - I can't see it at all in the SSAO Pro directory, and because I deleted the original folder before importing I've lost it altogether. Was it removed on purpose or is this an accident? The SSAO looks a lot better with the noise texture so I'd love to get it back.

Thanks, great asset.

 

I'm trying this in my VR game, does this use depth? The effect is there but at one depth level, like a pane of glass across the game that has the SSAO on it. It's on two cameras in Unity5.
Thanks

 

fair enough, thanks for the info.

 

I'm getting the error "Unsupported shader (SSAO)."

Any idea what could be going wrong?

Edited:

FIXED!

I tried deleting all the source files and re-importing, leaving everything in its default locations -- now it works...

Is it not possible to put the files elsewhere? I hate clogging up the root of my project with third party assets.

Thanks!

 

I'm having trouble with Cutout objects in Unity 5, forward rendering. I am using Standard shader set to Cutout.
See the effect I am getting in the screenshot:

For some reason, SSAO shades the invisible parts of the quad. The same thing happens even if I am using Transparent variant of the standard shader.
Setting the render mode to deferred fixes the issue, however, I can't use the deferred mode because of Unity's bug with speed tree shaders.
Do you have any idea why this is happening or how to fix it?

 

In Unity 4, to get full normals you needed to modify Unity's internal Camera-DepthNormalTexture.shader to also write out the normals from the texture instead of just the geometry normals. Not sure how much of this has changed for Unity 5 as I have not looking into it.

 

Hey man. I just purchased your asset and it is one HELL of a plug-in, but I'm having some issues with transparent objects, particularly the hair shader in Alloy. When you enable SSAO pro, you can see the background geometry through the hair (it's more obvious if you enable show AO). I've already told the designers of Alloy about it. I'll post a picture of this later

 

Here is the issue I am having... I turned the transparency to 0 so you can REALLY see the issue... you can see the wall behind the character. I am using Deferred Rendering.

 

I see. Thank you for your explanation.
I replaced the quad with a circular mesh to avoid this issue.

 

hi Chman,

we've got a Unity 5 scene with forward rendering using SSAO Pro and have some shadows-only meshes that are getting their invisible meshes shaded with ambient occlusion. Obviously the shadow casters are writing to the depth buffer and ssao is using the depth buffer to determine the ao... is there any scene setup or magic shaders to render these shadows without the invisible shadow caster meshes rendering their ao?

I've tried multiple cameras, hacked up some depth-only and shadow-collector shaders to try to layer the meshes and scene up correctly, but nothing has worked so far. It looks like the shadow collector shader stuff from Unity 4.x is deprecated (the shader source says it's only there to make older shaders compile), and I don't know enough about the current shadow rendering to know if there's a shader to capture just the shadows for a mesh which could be rendered from another camera or shader replacement trickery.

Any ideas, or are invisible shadows-only meshes (either using the Unity 5 mesh renderer setting or using a custom shadows-only shader) not really possible?

Thanks for any advice.

 

No worries, Chman - thanks a lot for your reply. I thought I'd check to see if there was something obvious I was missing that might work around the issue, like multi-camera, a special shadow collector shader, or changing when the ssao shader ran during the rendering or something. It looks like ssao will have to go for this project...

ps. I noticed the latest Unity 5.0.1p1 did an automatic script update on one of your v1.4 editor scripts as well - I'm sure you're probably aware, but thought I'd mention it just in case.

 

Hello Chman,

Has anyone reported black dots when using your plugin on AMD Radeon based video cards on windows? Several of my users have reported them, and disabling SSAO pro fixes the problem.

There's a couple of screenshots here when you can see them along the terrain:
https://trello.com/c/QgMY3njt/114-dots-on-screen

 

Using the SSAO pro (I just bought it) I am loosing the sort of shadows I got for the terrain's grass when using Unity Screen Space Ambient Occlusion. The following example is for a terrain without a lightmap.. Any suggestion? (Using Unity ver 5.01p2)

 

Here my situation (light deferred / gamma) :

 

I did some experiment and the problem is present also with lightmapping and with any kind of light (deferred etc.). To replicate the problem in Unity5 5.0.1p2 Windows 64:

1. create a new project
2. add the Environment standard asset
3. Create a terrain with grass (I used GrasshillAlbedo for painting 2D and GrassFrond01AlbedoAlpha for the 3D grass)
4. add SSAO pro
5. add SSAO pro to the camera
6. see the results

 

Well..
May I suggest you to include terrains for next versions?
Thanks any way

 

Hmp. It sort of makes the asset unusable since it ugly's up the screen of about 25%+ of the player base. So no fix or workaround in sight?

 

I'm getting a conflict with the UnoShader Unlit, it's showing up on top of the objects. This problem wasn't happening before unity 5.

Screenshot:

The AO from the floor behind the objects that are using the UNOShader are showing up on top of those objects

Any ideas what I could look into to to fix this?

 

Tried with all of the rendering paths, same result.

"RenderType" = "Opaque"
"Queue" = "Geometry"
"LightMode" = "ForwardBase"

Here you can see a picture of the scene with Unity's AO, and a Show AO only to better see what is happening. Funny thing is that in Unity 4 it worked like a charm I guess something changed from 4 to 5 in that regard.

I also sent a mail to the author of UnoShader asking about the problem to which he replied:

Added some cubes behind the plates with some really obvious AO to see if it would bleed in front of the plates using Unity's AO, definetly not bleeding D:

Hi Chman,
Just sent you an email, I'm the author of UNOShader =)

 

Thank you both for the help Hope it's something easy to fix.

Went back to a copy of the project I had that was still in Unity 4 to take a screenshot, this is what it used to look like before I made the upgrade to unity 5:

Hi guys I think I found the problem, the fallbacks on the new stuff in unity 5 includes Shadowcaster information stuff, which I'm assuming helps with normals and stuff.

The fallback in UNOshader that I wrote doesn't have it. once I add the shadowcaster part, all works well again.

So Dan for now download this
www.unoverse.com/unoshader/fixes/fallbackUNLIT_1_3_fix.zip
and replace the one in your directory ("UNOShader/Bin/Shaders"). I will update the asset store with a patch later on if this fixes the problem.

Thanks guys =)

 

Yay! now it works! thanks a lot! both of you \o

 

I did

 

awesome! use that update for now until I update the store.

Chman that is one awesome tool btw!
