[FREE] Subpixel Morphological Antialiasing (SMAA)

Nice! so unity needs to expose stuff for extended versions?

 

Very nice cheers! I own colorful and ssao pro and theyre both great (theres a plug for you) so this is appreciated

 

Lovely stuff. But a mini rant if I may?

The direction Unity's headed in is terribly sub-optimal. We're seeing vast amounts of redundant calculation that could be stuff calculated earlier or elsewhere in the chain.

For example colour correction, tone mapping, dof, antialiasing, motion blur, these are all effects that depend on resources that could be shared like velocity buffers, or blurred buffers, it's getting kind of insane and for framerate's sake might need standardising somehow.

It's not important to a hobbyist but for a console dev or someone targeting lower powered hardware, it's practically half of your frametime gone when really it should just be a single minimal impact.

 

Well perhaps we can get something going. If enough clever people sit down together, clever S*** happens. Essentially what we're looking for is a series of solutions for global textures to get generated. We know we need a number of high quality blur buffers and so on.

I'm thinking much like you can define the deferred shader in Graphics options, you could configure and define textures that must be there. I'm not sure if that's the right place for it. It could be on the camera. Failing this we could just have the best authors work together. The comes a tipping point where it's necessary to collaborate with unity's support. @robert or @Aras might know best.

For example @sonicether does great bloom. He generates a number of high quality smaller bloom textures. We can and should be using these everywhere in a standardised format if it's generated already.

That still leaves the issue of combining but at least a lot of the setpass work is done for us. I'd like Unity's input on that. Sorry for derailing your awesome thread, but its semi-relevant at least.

UE4 has the edge here, it's somewhat locked down and optimised, and Yebis goes much further, doing a number of effects all with minimal passes.

 

woot.

 

Thanks for this! Here is a comparison shot at 4x zoom between no aa , built in fxaa3, and your smaa ultra preset

 

Yup fxaa -> no more texture detail or specular highlights for you

edit: thanks for typogenic too, there is no project i dont use it

 

FXAA is still very quick though. Grabs his coat.

 

Wow. This is awesome. Looks fantastic and gave me a bunch of FPS back over FXAA. Thanks for the hard work and the liberal license!

 

Thank you !!!!

 

Amazing! I can't thank you enough.
This is exactly what we needed right now.

I'll test it on my Macbook later, if someone isn't faster.

 

Sorry for the dumb question, but i could not find the answer in the docs...
After a few hours, i finally managed to reference SMAA component from another script ( My GraphicOption script )...
I add to " use.Smaa" at the top of the script to then be able to cache my " public SMAA var".
What i am trying to do now, is to be able to change the quality via my GraphicOption script ... I tried different syntax but none seems to be working... If any of you could point me in the right direction, that would be really appreciated...

Thanks !

 

Tested on my Macbook Pro Early 2011 with AMD GPU.


A comparison I've made on my PC:



The difference clearly visible.
Thanks for your awesome work!

 

Looks really nice. Thanks for making it available for the community for free!

 

A thanks from me also, my game isn't ruined by crappy blur anymore, hurray!

 

What's the perfomance of Supersampling compared to SMAA?

About OpenGL performance:
I'll look into it when I'm at my Mac the next time.

 

Ah, okay. It might be useful when taking screenshots for advertising your game or so.
Would be awesome, if you can share it

 

Thanks for the tip
Are you currently working on the T2x version?

 

Thanks a lot , i am gonna try that right away !

 

Bump, since it's awesome.

 

This looks awesome, but is there any way to have a specific version for Unity 4 ? At the moment it has some errors I was unable to fix and upgrading to U5 is not an option

 

Wow, this looks great -- thanks for sharing! Unity's anti-aliasing is really, really crappy (and, weirdly, slow for the results you get) so this looks like a great alternative.

Definitely can't wait to give it a go. Thanks!

 

This sounds great. And free too!?

If I add SMAA to a camera I get spammed with errors though. The first is:

"NullReferenceException: Object reference not set to an instance of an object" on line 60 of SMAAEditor.cs:
m_CustomDiagDetection = m_CustomPreset.FindPropertyRelative("DiagDetection");

And another that seems to be from this on line 80:
EditorGUILayout.PropertyField(m_DebugPass, new GUIContent("Debug Pass", "Use this to fine tune your settings when working in Custom quality mode."));

EDIT: I can get around the errors if I drag the SMAA script into the component list rather than pick SMAA from the list.

EDIT #2: Holy CRAP, this thing is great! Plugged it into my game and got excellent results with the default settings. I had just converted to HDR a few days ago and ended up just giving up on post anti-aliasing due to losing tons of detail. But this thing is great. Finally HDR with AA is a reality.

 

Sweet! I friggin love you man!

 

For some reason, I'm getting errors preventing it from working. I got three errors like this:

Invalid pass number (1) for Graphics.Blit. Material=Hidden/Subpixel Morphological Antialiasing, npasses=1
UnityEngine.Graphics:Blit(Texture, RenderTexture, Material, Int32)
Smaa.SMAA:OnRenderImage(RenderTexture, RenderTexture) (at Assets/SMAA-Unity/SMAA/Scripts/SMAA.cs:237)

And then it becomes disabled.

Using Macbook Pro.

 

Ah, yes, I deleted it and re-imported it and it fixed the three errors. I'm just getting a warning now when I run the game:

GLSL shader load error (stage 2 shader 62):
ERROR: 0:132: Incompatible types (bvec2 and bool) in assignment (and no available implicit conversion)
ERROR: 0:247: Incompatible types (bvec2 and bool) in assignment (and no available implicit conversion)

And have no idea what that means. My shader knowledge is quite limited at the moment.

 

Great job Chman ! Finally a great antialiasing for Unity 5 !

 

Muuuch better than FXAA.
But losing against standard hardware AA when it comes to thin window frames in architecture facades.

Still this cool thing could mean that I may use HDR in future - thanks a lot!

 

@Chman
This is fantastic. Thanks!
Although, it would be great if we could use it for Unity 4 as well. Unfortunately I am depending on Unity 4.0.1 for some projects and proper anti aliasing would really make a difference. Would gladly buy buy you a coffee if you could check it for Unity 4 compatibility.
Also, is SMAA eligible for mobile?

 

I can. Going to deploy test build to ios tonight, will include SMAA and let you know how it goes.

 

Will test for Android 5.0 on Nexus 5 tonight! Thanks for the mobile support.
