NVIDIA HBAO+ Image Effect - Sample Project

I Had downloaded 2.3, if now is 2.4 I need to Download.
If I remeber the GFSDK_HBAO_distro_r2.3 was made for Unity 4+
So. If you want to use the x32(86) Version in unity 5 You need to Recompile The shaders that is in the example.
See my other post.
Then if you want The plugin for unity 5 x64 You need The lib folder , include folder and plugin source folder
You need to download everything. And find x64 libraries.
Then Follow the above steps in order to compile the plugin for x64.
After Compilation, If you want the bouth x32 an x64 you need to Chage the name of the new plugin,
Copy the HBAO_Plugin
Rename it to HBAO_Plugin64
and the name of the script to HBAOPlus64
And in the script (HBAOPlus64) you need to change some line of code for script to call the new name of the plugin
If not, Delete the x32 one and keep the x64 one with the same name
See my video.!
And my steps abobe.!

 

I think they removed the GFSDK_HBAO_distro_r2.3_cl18967762 which contained library for x64

and now The GFSDK_HBAO+_distro_r2.4_cl19426158 is the source. Without unity sample.
So
In 2.4 You will find a folder Called lib. In this folder are de Dll and the libraries for x32(86) and x64
The dll need to be in Unity project root
But first copy those Dll and lib files in lib folder where is 2.3 lib folder
You can use GFSDK_SSAO.h from 2.4 lib folder if you want and overwrite the old one witch is in include folder.
Now. in hbao_r2.3 You have a folder called unity with 2 folder . One folder called plugin and other is the uniy sample scene for unity 4.6 I think.

In Plugin folder you have the source code VS2012 and in that folder is the HBAO_Plugin.sln ....
Open HBAO_Plugin.sln in VS. and follows my steps from above...

 

Question to smb02dunnalI:

Instead of using the registers hack why not simply use a Blit to fetch the depth from unity to a RenderTexture and simply passing the handle to the plugin ?

 

Thanks man. please try to fix it for Unity5.

 

Here you go guys, the plugin version 64bit for Unity 5, compiled in release mode, using HBAO+ v2.4 and without the ugly registry hack so you have full control over your depth buffer, it might not change much but its way cooler.

Please let me know if it works fine on your rigs.

 

@matmuze
That's against their EULA , they don't want their stuff shared outside their website , just keep the stuff you made, remove the dll,libs and sources that belong to NVIDIA.

And by the way , is there anyway you can try to pass the normals data (i used the depthnormals texture and also i tried using the gBuffer's normals) , i tried once but it came up with a mess (same for both) , probably because unity's camera view matrices are different than what HBAO+ expects...

 

The normals from unity are either in world space, in the case of deferred rendering or view space in the standard depthnormals buffer.

If the deferred normals did not work it might mean that your must convert to it view space, which is trivial to do in a simple blit operation.

In direct rendering mode the depth and normals are encripted together in the rgba channels, on way would be to blit the depthnormals buffer as I did in the sample and to decode the normal during the process, once you are done you can simply pass it to HBAO if you are not scared of getting your hands dirty with native plugin coding.

It is not so hard to achieve really, let me know if you need help.

 

So , I should make a shader that multiplies the World Space normals by the Camera View Matrix , Then do the same thing you did to pass the depth?

 

What's with the licensing. Can we use it in commercial projects?

 

when turn on forward and 8x antialiasing camera fliping on vertical. how to fix that?

 

I am also having the flip anti-aliasing issue.

 

Just invert the output in the shader code

 

I ended up deleting the project because when Imported into a new project I kept getting the HBAO Plugin DLL Not found error.

 

All works fine in Unity 5 editor window , but I tried make standalone build of your demo. I opened executable file and I have got black screen (*.dll files are included in build). How can I use HBAO effect in my standalone Win64 DirectX11 build ???

 

Similar question.

 

From NVIDIA Gameworks EULA at : https://developer.nvidia.com/gameworks-sdk-eula

 

We just upgraded to Unity 5.1.1 and start getting "Failed to load 'Assets/Plugins/HBAO_Plugin.x64.dll' with error 'The operation completed successfully. ', GetDllDirectory returned ''. If GetDllDirectory returned non empty path, check that you're using SetDirectoryDll correctly." errors.
5.0 had not had that issue either. I had not tried to rebuild the DLL yet, though.

On the side note, before we get to that, I had to fix the DLL name setup part where it was checking #if UNITY_5_0, cause obviously Unity 5.1.1 has a different define. I did not find any UNITY_5 defines, which would work for all 5.X.X, but that is a separate issue.

 

Ok, I tried to rebuild the project wit VS2013. New Release x64 DLL is 1K smaller than the on included in the original package. However, the error still stays.
I have found that some other plugins had the similar issue and the posted on their forums "The problem seems to be related to a VC++ dependency which is missing on some systems. This doesn't explain why the problem only presents itself in Unity 5.1 though so I'm not entirely sure.". However, there was no indication what was that problem and how to solve it.

Anyone knows what is all that about?

 

Yeah the build doesn't work. It end up with a lot of error "DLLNotFoundException.....' Please help

 

I'm getting this too and I'm absolutely perplexed by it.

 

Just needed to toss the GFSDK_SSAO DLLs into the base project directory.

 

Thanks, Trent.
Apparently the location of DLL is expected differently depending whether you run in the editor or standalone build. Editor wants GFSDK_SSAO DLL in Plugins; standalone build - in main folder, next to EXE.

 

Someone has fixed it?!!

 

just go to the HBAO+ page on the gameworks website they have samples for unity, i think its the same as here and it contains both x86 and x64 with source code

 

Hey guys, was anyone successful in doing this for Flex?
https://developer.nvidia.com/flex

If not, would it be possible to use Flex in Unity, without having to write a C++ wrapper for Unity to flex?

 

You're going to have to write a wrapper.

 

Hi, I have the following problem when trying to use the DLL
"Failed to load 'Assets/Plugins/HBAO_Plugin.x64.dll' with error 'The operation completed successfully . ', GetDllDirectory returned ''. If GetDllDirectory returned non empty path, check that you're using SetDirectoryDll correctly."
I'm new using DLL and have no idea what is wrong , help.
thanks

 

It seems hbao sample from Nvidia works fine after changing #if UNITY_5_0 string to #if UNITY_5 in HBAOPlus.cs despite on error

Just restart the editor and check there is two GFSDK_SSAO dlls in the root folder of your project.
Also you'd need these dlls in the root folder of your standalone build near the executable.

 

Hello,

I am getting a black screen [ fading into black once turned off and on ] once i use the HBAO+ in a windows build.
It does work in the Editor without any problems.

Does anyone have a fix fo this? or a tutorial of some sort on how to fix it so i can use HBAO+ in a build?

Thanks in advance, Regards.

 

You might want to fix the warning where you use GL.IssuePluginEvent(eventId) as it is now deprecated in newer releases of unity.

 

Same problem here. How should I fix it? How should I update 'GL.IssuePluginEvent(eventId)' to 'GL.IssuePlugonEvent(callback, eventId)'?

Thanks in advice.

 

IssuePluginEvent(eventID) is not used anymore, any updates to this package?

 

Does anyone have an updated binary?
