Official Pixel Perfect Preview Package

That's good to know, thanks!

A status boolean and an event we can subscribe to would be nice in that case!

 

I'd like to know how others are handling the readiness of the PixelPerfectCamera.

I created a cameraInitialized bool in my GameManager singleton which is flipped to true once the pixelRatio on the PixelPerfectCamera is calculated. When I first started using the PixelPerfectCamera I expected the calculated results to be available in the Start() method and was wondering for hours why the pixelRatio was always 1...

 

You could start a watcher coroutine or do the calculation yourself.

 

how to get ride of that red text(error) it keeps showing in some resolutions like 800:480 ? i tried to change the Assets pixel per unit and reference resolution settings but nothing new.

 

no idea in unity forum ????

 

@MrZzzero
Comment out line 237 and line 242 in PixelPerfectCamera.

 

thx for the reply but what do u mean ? is it a problem in the script of the pixel perfect camera ?? i didn't touch it ; is it a bug in the package of unity version 2018.2.3f1 i tried to redownload the package but i have same problem even in new projects ???

 

Its not a bug, its by design.

 

So there is nothing wrong with my camera or project settings ? another question is there a way to change the view size of this pixelperfect camera ,i want to zoom out ? thanks in advance

 

Increase orthographic size.

 

I'm having trouble using this script correctly.

My settings are:
PPU 32
Reference Resolution 640x360

If I play in resolution
1024x600 I see way too much of the stage, orthographic size becomes 9.375

In resolution
1280x800
it plays perfectly

But then in all these resolutions I see way too much:
1024x576
800x480
854x480

I don't understand why it can't just show the proper amount of 'tiles' either horizontally and vertically. It only works OK on some resolutions.
Very confusing.
I just want to show around 20 tiles wide. Height can be flexible.

 

I didn't follow your conversation but I can't change the orthographic size when the script is attached

 

like what rose said u can't change orthographic size cause i think the perfect pixel script who do that auto , this option need more clarification from it's creators i mean this package .

 

Did you set it up to crop the sides? This should get rid of the problem of seeing more of the stage than you are supposed to.

 

Then I have a lot of black around the game, haha.
Isn't there a way to make it bigger without making it so blurry? (If I turn on Stretch it doesn't look any better than without the camera.)

 

I'm looking through PixelPerfectCameraInternal trying to find the right place to stretch the viewport height by 1.2, so effectively every pixel appears to be 1/5 taller than it is wide, to emulate the old 320x200 to 320x240 CRT aspect ratio correction. I understand the viewport will render outside of the screen, which is fine since I'll be designing everything to fit in the section that is within the screen. Which part of the script/class should I modify to allow this?

 

The ideal way for stretching would be not to use the blurring AND/OR not to stretch the smallest version of the texture but the one you would get when cropping X and Y... it auto fits the texture into the window. If you stretched that version it would look nicer. From what I've seen it is how GameMaker Studio 2 does it. When you resize the window it is blurry for a second and then it catches up and becomes crisp.

 

Yeah, I'm just trying to emulate this effect:

The left is square pixels, the middle is what would happen if the rendertexture at the reference size were stretched, and the right image is what would happen if the upscaled rendertexture were stretched. You end up with nice, 1:1.2 width/height pixels, whereby the width of the pixel is the same, but the height is now 1.2, as it has been stretched after the upscale, which is allowing this.

 

Is there a way to get this script to respect the viewport rect settings on the camera? I want to utilize pixel perfect rendering but only within a subsection of the viewport. Currently with this script enabled the viewport rect is ignored and it fills up the full screen.

 

Thank you for the update! I'm sorry if I came across as too complainy. I'm really excited for your team's great work on this package as this would be the last thing needed for me to drop GameMaker completely for 2D projects.

 

Whereabouts is camera.aspect? Your example looks great! As each pixel at 8w*9h, I'm looking for each pixel to be 20% taller than it is wide, which is a bit more than your example. What changes should I make to get it at least the same as yours, then ready for tweaking?

 

Can you elaborate on what this way would be?

 

Is there some way to do pixel perfect post processing with RT upscaling? Im trying to do screen space 2d reflections via OnImageRender, but when i distort the reflections, it clearly becomes pixel imperfect. Is there some way to do post processing on the upscaled RT specifically?

 

Are you around at the moment? I've pmed you an example, unfortunately that method seems to stretch the viewport before the upscale and it keeps the image within the screen creating a mushed, 4:3 looking image?

 

Nevermind. Got it done via Command Buffers using CameraTarget rendertexture.

 

post effects that need to be pixel perfect to work well
- scanlines
- crt filter

 

Sure thing! I just needed post processing to be done in the same resolution as the upscaled RT and conform to the pixel grid, but OnImageRender seemed to do it on a full screen resolution RT. Its much better in motion, so heres the gif:

 

Sorry! Here's the script I put on my mainCamera:

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4. public class AspectCam : MonoBehaviour {
5. public float aspect;
6.  
7.     // Use this for initialization
8.     void Start () {
9.         Camera mainCamera = GetComponent<Camera>();
10.         mainCamera.aspect = mainCamera.pixelRect.width / (mainCamera.pixelRect.height * 1.2f);
11.     }

Here's what it looks like before I use it:

And here's what it looks like with that script attached:

Any ideas why it seems to be mashing the pixels up before the rendertexture is blitter, and then squeezed into the window with pillarboxing? Here's how I was expecting it to appear (and I'd just readjust the position of the camera and UI):

 

Doesn't appear to be improving it by adding to update, is there anything else I can try to get the above effect?

 

Interesting video about retro games, including discussion about non square aspect ratios

 

Wow thanks, I'll take a look! Non-square pixels were almost a standard before SVGA so it's nice to see it being discussed.

 

Well, that takes me back. I honestly forgot that I had issues with it. Well, here's the project, I still can't make parallax work correctly. It jitters too much, even when using rounding function provided by the camera script.

https://drive.google.com/open?id=1AGlJ134nLweMTL8kDZNYVz60vMc5aJPF

Used Unity 2018.3.b3 for this project. Each sprite has a parallax script and in it there is a checkbox that determines whether to use raw position input or have it rounded by the camera script.

Thank you.

 

Hello, I have an issue with the camera snapping.
I am prototyping a game heavily based in post effects, so I decided to go into a low resolution pixel art direction that could help me by heavily reducing the work of the fragment shader.
So, this is how I procceded:

1. I downloaded the demo project and opened the tileset scene.
2. I modified the camera to render the gameplay to a 320x240 texture (same as the pixel camera configuration), no bilinear filtering
   
3. I placed the texture into a plane and the main camera points towards this plane.

Seems to work wonderfuly until you move.
It seems that the camera is not snapping to the pixel.


This seem to be creating a strange behavior where in the final render, some pixels are bigger than others:


When the camera is scrolling is horrible because each pixel row and column is changed on every frame and it looks like an underwater effect.

Is there any way to workaround this? Am I missing something? It should be kind of easy to render one-to-one pixels but it seems not.

In fact, it seems to be something related to the snap to pixel because the main character doesn't snap:

 

So ive been trying to find a way around excessive blurring when using stretch fill, and ive found that upscaling the low-res RT with point filtering by a integer amount to the closest resolution to the screen resolution, and then outputting that RT with bilinear filtering, produces a much better and clearer results. Its obviously not a panacea, not pixel perfect since its impossible, but it produces much better results than default stretch fill now. Heres the screenshots of the results:

Reference (900p):


Default blurry stretch fill implementation (1080p):


Custom stretch fill (1080p):


Custom stretch fill (1440p):

 

Hey! Currently trying to reduce the excessive blurring when using stretch fill too. Can you tell me where do you get access to the low-res RT ? Thanks

 

You have to manually create the copy of the screen contents via command buffers. I.e like this

Code (CSharp):

1. copyBuf = new CommandBuffer();
2. copyBuf.name = "Copy screen";
3. copyBuf.Blit(BuiltinRenderTextureType.CurrentActive, upscaledRT);
4. m_Camera.AddCommandBuffer(CameraEvent.BeforeImageEffects, copyBuf);

RT doesnt have to be upscaled, i just use the upscaled one.

 

Got even better results using custom Lanczos2 sharp filtering from this thread: https://forums.libretro.com/t/lanczos2-sharp-shader/1215/61
1080p bilinear:

1080p lanczos:

 

Would you willing to share this? I've been interested in how an upscale to closest integer size with smoothing on that upscale would look, the lancos2 version looks awesome.
