Official New Post-processing Stack (Pre-Release)

Thanks!
I do have one of those. Looks like I have some work to do.

I got used to not using namespaces, because Unity didnt support them at first.
Then when they were supported it took me a couple years before I started to use them.
I suppose I should spend some time properly namespacing all my classes.

 

So, is Unity giving up on their SSR implementation? I don't see any files related to SSR in the V2 of the post processing stack... I wanted to upgrade but lighting doesn't look great without it.

 

Wondering what's happening in SSRR land as well... last implementation seemed to overthink it and try too hard.

 

They are working on a new SSR implementation, You can see Kink3d's comment here: https://github.com/Unity-Technologies/PostProcessing/issues/186

Update: Chman confirmed that SSR is being reworked. https://github.com/Unity-Technologies/PostProcessing/issues/215#issuecomment-313429806

 

I have this question now, which is better?

Post Processing Stack or Beautify ??

Which one is more performant?

Do Post Processing Stack also supports VR?

 

Dude... they are different effects. Beautify is like a last pass on colors and some other details which enhance overall appearance (well, it's more than that, but hard to explain quickly, it tries to fix artifacts from other post effects too, etc). Beautify is not meant to replace standard effects. Then, as far as I know most effects in the stack support VR, but the ones that don't are listed in the wiki in the github (at least I usually just check them there).

Anyway, make sure to read the explanation/manual for all the effects you use...

Edit: oh, sorry, I checked the link and I see the author has indeed added some random effects to Beautify since the last time I checked it. But, it still doesn't have all the important ones (since that's not it's purpose, anyway). You still won't get antialiasing, Ambient Occlusion, fog, chromatic aberration, color correction and SSR from Beautify (all important standard effects, Beautify only gets Bloom and DoF from the main effects). For the effects which are shared between both packs, you could just test them in each pack and activate only the one which looks best in your eye (bloom and DoF are the only ones you'll have to try to compare in performance, nothing that a quick build won't show - with an fps counter).

 

No, tonemapping is not broken in 5.6. The reason it is not broken is because you have not filed a bug report and got a case number.

In short: I think it's your fault it isn't working, but if you can explain your problem clearer, I'm sure someone can help you fix it. Or file a bug report. It could be you're not using the right version of the post effects or you might have camera set up incorrectly.

 

Sounds to me you have MSAA enabled?

 

I'm not sure what's going on -- I"m following the instructions here: https://github.com/Unity-Technologies/PostProcessing/wiki

However, I don't have a file called PostProcessLayer.cs

Any idea what that's all about?

 

Have you downloaded the v2 version?

https://github.com/Unity-Technologies/PostProcessing/tree/v2

 

Yep -- first did the asset store version, and then just to be sure, did the download from GitHub

 

Post-Processing Stack 2.0.0 Beta 1 is out: https://github.com/Unity-Technologies/PostProcessing/releases/tag/2.0.0-b1

 

Fantastic news!
Is there a changelog somewhere about it?

EDIT : Nevermind, I just clicked the "quickstart" section and found it.

 

Is there a way to get a handle to the effects in the post process volume? I want to interpolate between two states with different vignette/chromatic aberration/bloom and can't find a way to make it work.

How do I achieve something like:
[Pseudo-Code] Vignette myVignette = PostProcessVolume.GetVignette();

I could work around by just changing the weight of two preset post process volumes but that feels a little bit clunky to me.

 

V2 already deals with that. It uses post processing volumes and you can define in each which effects are going to differ from the global settings, then blends from one profile to another (or the specified differing settings). Check the Quickstart page.

If you are stuck with V1, then there's also a free third party plugin called Post Processing Volume that blends between profiles too.

 

Hello, I'd like to know how did you make it work on Vive? Which component should I add the post processing stack on? and if you encountered any problems using the effects in VR

 

Hello

We've found out that Temporal Anti-aliasing also jitters the projectionParams built-in variable (near and far plane). Is this intended behavior? This breaks effects that use near/far plane when the planes are relatively far apart. Small variations in these parameters cause flickering.

 

This is BEAUTIFUL!!!! Will have pictures once the PL finishes... unfortunately, my old profiles no longer work with the new beta , so for now I will stick with the stable version until the next update, I can retain my settings.

 

Hello,

I have a procedural based voxel game. I was using the first post processing stack until now, I only want depth of field and Motion blur.

I am using Unity 2017 since yesterday. Performance is extreme important for me, since my voxel landscape has a lot of Polygons.

I am satisfied with the Beauty of the first post processing effects, do you think I should use the 2nd one? Does it offer better Performance?

Thanks a lot!

 

Adding Post Processing Stack seems to disable my FOW shader.
If I enable the post processing the shader stops working.

Any ideas on why this would happen and possible solutions?

Shader Code:

Code (CSharp):

1. Shader "Custom/FogOfWarMask" {
2.     Properties{
3.         _Color("Main Color", Color) = (1, 1, 1, 1)
4.         _MainTex("Base (RGB)", 2D) = "white" {}
5.     }
6.     SubShader{
7.             Tags{ "Queue" = "Transparent" "RenderType" = "Transparent" "LightMode" = "ForwardBase" }
8.             Blend SrcAlpha OneMinusSrcAlpha
9.             Lighting Off
10.             LOD 200
11.  
12.             CGPROGRAM
13. #pragma surface surf Lambert alpha:fade
14.  
15.             fixed4 LightingNoLighting(SurfaceOutput s, fixed3 lightDir, float aten)
16.             {
17.                 fixed4 color;
18.                 color.rgb = s.Albedo;
19.                 color.a = s.Alpha;
20.                 return color;
21.             }
22.  
23.             fixed4 _Color;
24.             sampler2D _MainTex;
25.  
26.             struct Input {
27.                 float2 uv_MainTex;
28.             };
29.  
30.             void surf(Input IN, inout SurfaceOutput o)
31.             {
32.                 half4 baseColor = tex2D(_MainTex, IN.uv_MainTex);
33.                 o.Albedo = _Color.rgb * baseColor.b;
34.                 o.Alpha = _Color.a - baseColor.g; //green - color of aperture mask
35.             }
36.             ENDCG
37.         }
38.         Fallback "Diffuse"
39. }
40.  

 

Is this optimised for mobile? I tried the beta and it killed mobile performance, as do all the official post process effects. However, optimised solution can be written, so it's just a case of making that a target for the effects.

 

Might of already been asked but where are the sunshafts? As well as the lens flare's appear to be messed up? They now render on the FPS controller behind the camera so they are no longer visible? I don't get it. They released this broken or I'm doing something wrong?

 

I was wondering if there are any simple scripting examples for v2? I set up some basic effects which I like including DOF, but quickly needed the ability to change the focus distance based on the distance from an object and can't figure out quite how to do it. I saw some scripting references for creating a quick volume, but I have a simple global volume I created out of runtime in the inspector and I just wanted to tweak its value for the DOF Focus Distance during runtime in script, how would I do that?

So far I've tried the below, which does not work.

Code (CSharp):

1. ppv = this.GetComponent<PostProcessVolume>();
2. DepthOfField dof;
3. ppv.profile.TryGetSettings<DepthOfField>(out dof);
4. float distance = Vector3.Distance(GameObject.Find("Main Camera").transform.position, GameObject.Find("Assembly").transform.position);
5. dof.focusDistance.value = distance;

Also tried to set it by using AddSettings to no avail:

Code (CSharp):

1. ppv.profile.AddSettings(dof);

 

This appears to actually change the value, but it gives unexpected results that are not correct looking:

Code (CSharp):

1. dof.focusDistance.Override(distance);

Is there an easier way to have a dynamic DOF that keeps a specific object in the focused area even if the camera is freely transformed around the scene (distance from camera to object can change greatly)?

It's unfortunate because the old DOF image effect script had a transform value to automatically keep an object in focus and works perfectly, except it appears to hit performance way more than the new one.

 

Are the post-processing profiles created with V1 compatible with V2?

I'm asking because when we upgrade Unity and the post-processing stack to V2, will the profiles be usable with V2?

 

I'm making stylized tree for my game. For creating shaders I use shader forge. I use many light sources so I'm using deffered lighting system. Best visual results are with using light attenuation node. However, it can only be used in forward shader. My problem with this combination is ambient occlusion. I see it through my tree. I currently use unity post processing stack. The problem can be solved by using "ambient only" checker, but the visuals are poor then.
I tried to use any other AO plugin, same results. The only way it worked was HBAO with normal reconstruct option, but it decreased my performance by 20%.

The screen below shows the problem, I also increased some contrast to make it more visible.

 

@bobi_z_nairobi, did you try the Foce Forward ot Ambient Only flags?

 

this doesnt help ;/

EDIT:
Ive Found a reason, removing vertex offset from shader solves it completely.... any idea how to animate it with vertex and keep proper AO?

 

Is is possible to separate some effects from stack? I want to use different bloom asset instead of this one. But it is better to put custom Bloom after Antialiasing to prevent flickering.

 

Any indications on how the effects stack performs on mobile (which is a wide range, I know)?

 

Already asked here:
https://forum.unity3d.com/threads/new-post-processing-stack-pre-release.435581/page-12#post-3146057

Killed mobile in the Beta

 

So, it sounds like you are suggesting that this is unusable on mobile. Would that be correct? I just want to know for sure before I attempt to find some alternative solution.

 

I think it's not compatible. because the new version has modified effects with some different settings (modified shaders).

 

Hi there. I'm using the stack v2, trying desperately to export a .EXR file to make a LUT, but Unity crashes every single time. I've already done it with most of the scenes from the game, but in the current one it won't work. The log file has an "Acces Violation 0xc0000005" code.
I've already sent the report, but I need a quick solution for this. Did anyone had this problem?

EDIT: Ok, it seems the reason is one shader in particular: Unity's SimpleWater4 shader (and Water4 too, actually). The scene I'm working on is placed in a swamp, which uses this shader. If I deactivate the water I can export the .EXR file with no problem, but every time I try it with the water active, it'll just crash.

 

Hi just started using Stack v2 Beta, Maybe a bug report or not.

Gamma and lift values affecting the scene at all times globally regardless of volumes. anyone else having similar issue?

 

is there some issue using LUT? whole screen becomes gray..

using 2017.2.0b4 and v2 stack,

 

It seems like most effects are killing the alpha channel when using it in conjunction with renderTexture, which is unfortunate. Unless I'm missing something..

 

Hi, i started using v2 as well... overall i think it is slightly more performant than v1.. but any idea or does anybody know why onprecull usage is high? is it because v2 effects applied at on precull??
strangely, even when i disable all effects while post process layer is enabled.. it still have impact on "precull"

 

@Chman it seems latest v2 are broken in 2017.1. I keep getting black screen glitch, and ambient occlussion not working.
and turning off AO make the screen black

 

Hello,

Any chance you could add color bleeding in the ambient occlusion? Or at least a color tint?

I'm using V1.

Thanks!

 

V2 seems to break with single-pass stereo enabled, both in forward and deferred, and even if all effects are disabled:

It looks like everything is rendering into one tiny little quad and everything else is not even clearing. Switching it back to multipass makes everything okay again:

Is this known behavior?

 

Hi everyone, just read this and wanted to chime in with some details about Beautify.

Firstly, Beautify is Single Pass Stereo compatible. It's being used in many games and platforms and users love it both in results and performance.

Performance is a very sensitive theme, especially when you compare two different systems as the results and implementations vary. What looks great in some way in one system may look and performs differently in another, especially on "mobile" which is a quite broad term.

To make things easier, Beautify provides 3 performance presets which uses different shader variants for some of the effects (ie. "Best Performance" uses less texture fetches or internal passes compared with "Best Quality" for the same effects, which is basically what usually determines performance along the number of draw calls).

Beautify can also be referred as a highly integrated and optimized image enhancement filter (which packs HDR dither + custom sharpening + color enhancement) plus a bunch of optional extra effects which are combined in the same pass.

The core image enhancement filter can work without depth information. In forward rendering path, the depth is computed using an additional pass so you can save ms if you're just interested in the core functionality. Again, Beautify turns this as simple as a global toggle (Best Quality, Best Performace or Super-Fast Performance).

On the other hand, some effects are both presently in Beautify and Unity's Post-Processing Stack although with subtle variations. They are:

- Bloom: in Beautify you have options for depth attenuation (focus bloom in short distance) + bloom culling mask (you can apply bloom just to a group of objects).
- Depth of Field: comes with bokeh + support for transparent objects + exclusion layers options.

Other effects that are only available in Beautify are:

- Anamorphic Flares.
- Sun Flares (video)
- Purkinje Shift
- Frame
- Outline
- Sepia
- Thermal and Night Vision
- Daltonize

Effects like SSAO, SSR and LUT support and extended color options are only available in Unity's Post-Processing Stack (and other Asset Store packages that seems to work also very well with Beautify like HBAO or Amplify Color). So yes, they can work together since each package comes with unique effects.

If you have question specific to Beautify, please feel free to ask on the corresponding thread: https://forum.unity3d.com/threads/b...ing-incredibly-crisp-and-vivid-scenes.401999/

Cheers!

 

hey, I've just updated my project from unity 5.4 to 5.6 and trying post-process stack to enhance my game's visual effects.
Then I found a very strange effect in my screen:


The color insides shadows is very ugly and forms solid color blocks, no details rendered in these shadows.
Then I tried to disable the post-processing behavior component

it got much better but still some strange color inside shadows.
Wondering if this is something about my hardware or I got some settings wrong?

I'm using deferred rendering and linear color space.

 

Right click on your Assets folder and select Reimport All. It's may fix your problem and is a useful way to fix upgrading issues

 

Thanks for the reply, but I tried to import it into a new project and they still has ugly color blocks.
I'll try this on another PC that has a better graphic card to see if it is a hardware issue.

 

It's unlikely to be a hardware issue as i experience this is using the post process stack along with Prism post effects, are you by any change using those? I believe some HDR -> LDR remapping might be going on and the same might be happening with other effects that are not Prism.

Prism + PostEffects Stack:


Prism only:


Notice the very clear banding on the middle character's face and the light source bloom.

 

I'm using Tenkoku dynamic sky that has it's own illuminating methods. I'm not familiar with rendering techniques so I'm not sure if Tenkoku used the same tech as Prism.

And you just reminded me that I can try out Prism post-effects and see if it can be a replacement of unity's post-processing stack. Thanks

 

I generally prefer the Prism, Scion or Beautify stacks to the Unity stack, but those does not have good AA or SSR solutions, so i kinda hoped to use the Unity stack for that ¯\_(ツ)_/¯.

 

Can someone please help me?
I am trying to modify my profile at runtime with UnityScript.

I tried to import EVERYTHING ha ha..

Code (JavaScript):

1. /*import System;
2. import System.Linq;
3. import UnityEngine;
4. import System.Collections;
5. import System.Collections.Generic;
6. import UnityEngine.Rendering;*/
7. import UnityEngine.PostProcessing;

It always gives me the following error:

Code (CSharp):

1. Assets/Scripts/CameraScriptA.js(9,8): BCE0021: Namespace 'UnityEngine.PostProcessing' not found, maybe you forgot to add an assembly reference?

edit: I'm using v1. The Asset Store version

EDIT:
SOLVED - for everyone having the same question:

I moved the the whole PostProcessing Folder to a 'Plugins' folder.
This way I am able to access C-Scripts from inside Unity Scripts.

 

Hi,
i remember in some of the earlier versions we were able to bake the current color correction to a LUT file from the Color Grading panel in Post Processing Stack and then use the generated LUT texture straight in the User LUT panel. Now i don't see this option. Is it no more available ?
