Official 2D Pixel Perfect is out of preview for 2019.3

This is awesome, been following for the last couple of years and it really is an excellent package. I've been waiting for the possibility of stretching the viewport post-upscale similar to how ScummVM and DOSBox simulate the old 320x200 stretched to 320x240 mode of old vga cards. @yuanxing_cai was working on this part, it was working okay at one point with some modifications, but it broke any UI stretching as all of the raycasts were in the wrong place. Is it possible this will be developed further in future verisons? The modifications were documented here: https://forum.unity.com/threads/pixel-perfect-preview-package.533433/page-4#post-4032814

 

I tried it with URP but it isn't compatiple, it says to use the pixel perfect camera from URP (it is still tagged "experimental") and that one doesn't work properly, crop doesn't work, upscaled render texture neither.

Could you please fix that?

 

URP 7.1.8
With more tests I'm seeing the crop actually works, but don't clear properly beyond the crop. The problem is with Stretch Fill active, when I start play mode it doesn't work, but if I uncheck and recheck the Stretch Fill option it starts working (still not clearing beyond the crop).

About the Upscale Render Texture I placed high resolution images to test it, and they should be pixelated, but I see no difference. With the main 2D Pixel Perfect package it works.

 

I'm slightly confused. Are there multiple PixelPerfect solutions? Is the one mentioned here only for the default (deprecated?) renderer?

 

I tried to search the previous thread about ways to zoom the pixel perfect camera in and out but didn't find any conclusive help. Is the case different now? How would I go about zooming the camera? In the previous thread there was a mention of post process zooming, how can I do that?

 

Is it possible to anchor a camera's view to a screen's border? Currently, the view is centered but I want to have a portrait screen aspect ratio with camera view on bottom and UI on top. Any advice on how to achieve it without a render texture?

 

This is awesome!

 

Hope this package gets more work!

 

Is it possible to make Canvas work properly with URP Pixel Perfect Camera? I tried setting Render Mode to Camera and assigned my Pixel Perfect Camera and tried all the options of the Canvas Scaler but only got poor results. Then I tried the Custom Scaler Script from https://forum.unity.com/threads/canvas-with-pixel-perfect-camera.768377/, the result is slightly better (UI Image with assigned Sprite seems to behave like other sprites) but Text is jittering when I move the camera. I set the mode to Scale With Screen Size and the reference resolution and PPU to the same values that the Pixel Perfect Camera uses.

 

Please allow us to disable bilinear on stretch fill, it's ridiculous to have to manually change the file every time we open Unity.

 

What is this error caused by? I copied the folder from Package Manager into my assets folder and removed it from package manager:

Code (CSharp):

1. Assets\com.unity.2d.pixel-perfect@2.0.4\Tests\Runtime\PixelPerfectCameraTests.cs(7,58): error CS0246: The type or namespace name 'IPixelPerfectCamera' could not be found (are you missing a using directive or an assembly reference?)
2.  

 

@yuanxing_cai Is it still possible to fork PPC from package manager into the /Assets folder? I'm getting the above error, and until bilinear toggle is added, this is my only long-term solution.

 

Any chance the URP version could remove the dependency on the 2d renderer? I need to work with the normal 3d renderer.

 

The last thread also went into detail when you last asked (https://forum.unity.com/threads/pixel-perfect-preview-package.533433/page-7#post-5165333) about this:

PPC is a good, solid solution for getting an accurate retro 3D look (although I think there were solutions on the asset store that were a little more thorough).

I updated to 2019 today from 2018 preview, and I'm really disappointed to see there is still no easy zooming functionality with this package. I made my own very simple fix in 2018 and I'm really shocked it isn't a standard yet.

Here's how to introduce a simple fix:
1) Open PixelPerfectCamera script in Packages\2D Pixel Perfect\Runtime
2) Add this around line 16:

Code (CSharp):

1.      public float extraOrthoZoom { get { return m_ExtraOrthoZoom; } set { m_ExtraOrthoZoom = value;} }
2.  

3) Add this around line 139:

Code (CSharp):

1. [SerializeField]
2. private float m_ExtraOrthoZoom = 0f;

4) Modify the OnPreCull method "m_Camera.orthographicSize = m_Internal.orthoSize" line to:

Code (CSharp):

1. m_Camera.orthographicSize = m_Internal.orthoSize + m_ExtraOrthoZoom;

5) Done! Now all you do is anywhere in your normal code, just set extraOrthoZoom to whatever you want (lerp this value for smooth zooming)

Code (CSharp):

1. (mCamera.GetComponent<UnityEngine.U2D.PixelPerfectCamera>()).extraOrthoZoom= 0.15f;

-----

Can we please get an official inclusion of this to the PixelPerfectPackage? It's really simple and is an expected standard, and not everyone wants to use Cinemachine. Modifying the package like I said isn't really user friendly and it doesn't work in Unity Cloud Build since it uses the default package.

Thank you

 

Argh, now it seems everytime I close/reopen Unity those modifications I mentioned in the above post don't get saved (or they are just overwriten by the package default). This didn't happen in 2018

Is there any way to change this behaviour? This is now a a huge inconvenience for me

 

@yuanxing_cai or @rustum I've been struggling for almost two weeks to have pixel-perfect using cinemachine (and I dont know if it matters, but I am also using corgi engine and tilemap). I have read the manual multiple times, today I just create a new project and just try the demo of corgi engine "retrovania" and did nothing more than build this scene (i didn't change anything). So, as you can see in the videos there is an annoying jittering when I try the build on 1920x1080 resolution. And there is a horizontal line "wave" when the camera moves on 1366x768 resolution. I also try on a 1360x768 monitor, the problems are not so annoying but are still there (btw, I have these 3 laptops resolution coincidently). I kind of solve the 1920x1080 and 1360x768 resolution ticking the Vsync count to "Every V Blank". However, that horizontal line "wave" that you can see in the second video is still there. I only have 3 laptops with those resolutions I mentioned, maybe it also happens in other resolutions. Do you have any solution for this problem?

Keep in mind that this problem is only visible (at least for me) when you build the scene, in the game window everything looks crispy!

 

@luispedrofonseca I just realize you are the creator of Pro Camera 2D. I was about to buy your asset, but I was wondering if it has the same issues I put before. I´ve asked some indie developer that use your asset and looks that it does not have these issues. However, I was trying to know if your assets have a way to change room (but no one of your videos, but those that for example you enter a house (so you don't see the camera moving but you just appear inside the house, of curse trigger by a bottom). Thanks for your reply.

PD: It will be wonderful to know also if it have any problems with the corgi engine (that I am using)

 

@yuanxing_cai Thanks for the reply. I am not sure I understood what you mean by override ....in my graphics driver (should I set anything outside unity software). Here my quality settings for your feedback:

 

Hi!

How do I use the scripting API for this package?

I'd like to get a reference to a PPC in the scene, then look at the current Pixel Ratio so I can scale UI elements by the same amount.

I'm struggling to figure out how to access anything from my scripts.

 

Hopefully this, based on my post a few posts up:
(mCameraComponent.GetComponent<UnityEngine.U2D.PixelPerfectCamera>()).pixelRatio

Although I agree. its hard to use and access. Hope it helps

 

Thank you for the help. I did try something like that already, but it doesn't compile:

The type or namespace name 'PixelPerfectCamera' does not exist in the namespace 'UnityEngine.U2D' (are you missing an assembly reference?)

 

Strange, sorry I can't help ~ it's working correctly for me using that namespace If you go to your Unity project browser, where your assets are, and look in "Packages", then "2D Pixel perfect->Runetime" then open the "PixelPerfectCamera" script, it should say the namespace at the top, mine says namespace UnityEngine.U2D

 

Yup that's exactly what I tried to begin with! ‍♂️ So I copied and pasted the references. The namespace U2D namespace is identified just fine, but the PixelPerfectCamera class is not.

Maybe @yuanxing_cai can help?

 

Sorry but I am having this problem with the Pixel Perfect Camera when I attach it to my main camera I get one sometimes two errors which makes the game screen grey and unplayable:

UnityEngine.GUIUtilityrocessEvent (int,intptr,bool&)


(The error below this text actually is constanly repeated but this number >481.399658< is different)
Screen position out of view frustum (screen pos 481.399658, 140.606964) (Camera rect 0 0 512 216)
UnityEngine.SendMouseEventsoSendMouseEvents (int)

Is there some way I can fix it the errors please?

Edit: Sorry for the emojis but the way the errors are set up the text turns into emojis.

 

@yuanxing_cai if I copy the folder into assets, delete Tests folder and remove the package, it still gives me errors:

Code (CSharp):

1. Assets\com.unity.2d.pixel-perfect@3.0.2\Editor\PixelPerfectCameraEditor.cs(7,26): error CS0246: The type or namespace name 'PixelPerfectCamera' could not be found (are you missing a using directive or an assembly reference?)
2.  
3. Assets\com.unity.2d.pixel-perfect@3.0.2\Editor\CinemachinePixelPerfectEditor.cs(3,42): error CS0234: The type or namespace name 'CinemachinePixelPerfect' does not exist in the namespace 'UnityEngine.U2D' (are you missing an assembly reference?)
4.  
5.  

I just want to remove the bilinear from stretch fill, I used to be able to, but I can't anymore. If the package was updated to allow this, I wouldn't have to do this.

 

Change the PixelPerfectCamera.cs script in

C:\Users\[username]\AppData\Local\Unity\cache\packages\packages.unity.com\com.unity.2d.pixel-perfect@3.0.2\Runtime

and it will be persistent.

 

Have you read all the others posts I’ve made about this? It doesn’t work, if I copy, it gives errors, no one mentioned any way of resolving those errors so I found a way that worked correctly (until the asset is actually updated to include this universally requested fix).

 

I would also really like an easier way to modify the package too, that works with CLOUD BUILD! (cloud build uses the default package no matter what).

If it were just imported like a regular AssetStore package that would be perfect, im not sure why it has to install very separate from the project

 

Great information here. Thank you!

9 months out of preview and still no bilinear toggle, is there something keeping this from being updated? @yuanxing_cai @rustum

I want to add an old tv/crt effect to my 2d pixel art game. I bought Retro Look Pro.
Now this asset has it's own render data for the universal render pipeline. I added that one to my Universal Render Pipeline Asset, my 2D Render Data is also in there, and I created an overlay camera that uses this render data. I then added this overlay camera to my camera that is already in the scene, and which has the pixel perfect camera object attached to it. Now the effect looks great, but this also breaks my pixel perfect camera. As soon as I turn this overlay camera off the pixel perfect camera works fine.
Now there is a warning in the pixel perfect camera that says it doesn't work properly when stacked, but is there a way to get the pixel perfect camera working and adding an overlay effect on top of it?

 

Hi !

I have some problem with pixel since a few day and I don't understand what I'm doing wrong...

I'm using the last Unity LTS : 2019.4.14f1 with URP 7.5.1 installed.

-First I created a new Pipeline Asset and 2D renderer, assign the renderer to Pipeline, then assign it to graphic settings.
-All my spritesheet are set to 32 PPU, ant Point set on Filter mode with compression set to "none"
-All sprite have a pivot point set with Pixel pivot
-I set 1/32 in Snap settings for "move", then apply all axis
-I added the experimental Pixel perfect script to the camera with settings :

Assets Pixel per Unit :32
Reference resolution: 320 / 180
Upscale Render Texture : none
Pixel Snapping: none

With all of this, my game is always blurry when the camera move....
I don't know if I can give more information that can be help :/
I tried Upgrade my project to newer version of unity, and nothing change ..

I'm stick with this since too long so if someone can help me i'll really appreciate !

Have a good day !

EDIT: My bad... Pixel perfect seems to work perfectly, My problem of Blurry seems to be a other problem independent of Pixel Perfect Script

 

As described in these two posts：
https://forum.unity.com/threads/pix...-with-2d-camera-stacking.948634/#post-6469433

https://forum.unity.com/threads/una...r-texture-on-the-pixel-perfect-camera.996548/

If can't stack the camera, then the upscaled render texture will affect the display of the text, and the small size text cannot be displayed and cleared. Please think of a way to render only the main camera.

The solution we can think of is to add a camera to display text, but pixel perfect camera can't be used when multiple cameras are stacked. Can we use it when only one camera uses pixel perfect camera?
Please think about it. Thank you

 

Is there any other way to display text normally when upscaled render texture is turned on？
This is very important to me, I hope to get an answer, will consider the problem of camera stacking, or not, I need to think about what to do next.

 

@Chris_Chu do you know why Pixel Perfect Camera behaves strangely when v-sync is disabled?

It seems the orthographic size of our camera changes when it's turned off and the sprites are no longer pixel perfect, making the game visually terrible.

It was mentioned above that nVidia and AMD offer the ability to override the application v-sync setting. How do we handle this case if a player has done that?
