[twin flicker]

over there , i have raised an issue relavant to this topic

[cosmic quiver]

witch link do i use?

[cosmic quiver]

neverminded i found it out thanks

[open gulch]

Is there a way to stop edges from being lit more than everything else?
It looks off, and is amplified by the post processing I have

[mighty stump]

Depends why they are being lit in the first place

[limpid bobcat]

Heyo im trying to get the effect of an explosion or the kick back of a gun in motion blur.
Similar to minute 11:13 in this video https://www.youtube.com/watch?v=g7e3xMR671E&t=365s

Any ideas ?

[mighty stump]

It's called zoom blur, a type of radial blur
For example https://www.shadertoy.com/view/3slSRj

[limpid bobcat]

Thank you so much ❤️ ❤️

[limpid bobcat]

ngl, i have no idea how to implement this.
Do i follow the code from their website to create a shader and then create a shader + material => insert said material into a blit ?

[mighty stump]

You'll first have to learn how to make post processing shaders for the rendering pipeline you use, then recreate the shader with the help of that example
Shadertoy's GLSL is probably not directly compatible with Unity's languages

[limpid bobcat]

Thank you for the guidance

[empty bluff]

Is there anyway to apply a post-processing affect only to the UI?

I want to use warping but only on my UI elements, which are on the UI layer

Whats the best direction to do this?

[topaz loom]

good question

i tried doing it sometime ago in urp but gave up

[hexed nova]

I would go with camera stacking

easy to do with URP

probably not so easy with other pipelines

[mighty stump]

Stacking post processing is not really easy in any pipeline
Post processing acts on the whole rendered image, so you can't just process the layers that have been overlayed, but can process both/all or the ones below

[topaz loom]

you cant postprocess the ones below

the ones below will leak to the top

all my efforts were in vain

[digital silo]

i need some help, i have a issue where post processing doesn't work in build mode, while in editor, it does

well not post processing entirely

only the pixelation and dithering effect

that doesn't work

[zinc estuary]

Does your main camera have pp on

[digital silo]

well look at the bottom message

only the "pixelation and dithering effect" doesn't work

other pp effects does

[mighty stump]

@digital silo I've heard that shaders that aren't assigned to any gameobject might get stripped out during compilation

[digital silo]

well its on a global volume

[mighty stump]

Apparently that might not be enough

[digital silo]

so what do i have to do?

[mighty stump]

I would try assigning the shader to a material that's on a gameobject
Or you could try searching for more accurate answers using this new information, if you don't want to throw solutions at the wall

[digital silo]

oh hey that worked

thank you!

[severe slate]

Hello, is it possible to enable post process Volume only for certain layers/objects?

[odd drift]

No

Only for certain camera

[rustic sandal]

I have a mouse over post processing effect, which uses layer switching and a separate camera to draw a blue outline around a moused over object. When I leave the scene, and return to the scene, using my level selection scene, my outline postprocessing effect stops working. Does anyone know what may be causing this?

[tropic turtle]

I'm trying to add a VHS noise effect on top of my camera. I'm currently using a video that outputs to a Render Texture that I add to a RawImage on a canvas. Is there a way to set different blend modes like Multiply or Screen for this? Thanks

[rose magnet]

you can use https://docs.unity3d.com/ScriptReference/Graphics.Blit.html to add an effect to a texture using a shader

[keen cliff]

hello

how can i add bloom only to some object !

[hexed nova]

With emission maps

[rancid viper]

im using the screen space reflection post processing effect in the built in render pipeline and im getting these weird dark spots. they dont look too bad in still frames like this but theyre very noticable in-game. any way i can get rid of these? havent been able to just by playing around with settings

[mighty stump]

Verify that the dark spot happens on other materials than that specific floor (prefarably a default material)

Looks like the normal maps are misconfigured which can cause all kinds of lighting weirdness

If that's not it, it could mean that SSR is falling back to environmental probes when it cannot reflect, but you might not have environmental probes so it falls back to black instead

[coral dock]

can i bring rtx to my game with gtx 1650 ti?

[mossy steeple]

Hey all, I'm not great with post processing or shader effects so I'm wondering if this is even possible-

I'm using the Oculus Quest Pro's passthrough camera in my project and I want to affect that camera feed with post processing like blur / sharpening

can a shader or post processing stack on a virtual camera effect a real life camera?

[shy thicket]

heyy, I'm trying to use post processing stack v2, I'm using unity 2022.1.20, I've been trying for about two weeks now but can't seem to get it, according to all the tutorials I could find I need to switch a setting in my urp renderpipeline asset, switching the feature set from integrated to v2, but when I go to where the setting was there's no setting there

[hushed ivy]

That post-processing stack isn't compatible with urp, only lwrp. Urp uses post processing volumes instead.

[shy thicket]

in that case, is there any way to get my post processing with urp to have autoexposure?

also, how do I use script to turn attributes of the post processing on and off?

[hushed ivy]

URP doesn't appear to have autoexposure. Not sure why.

But it does have an exposure setting in the Color Adjustments override. To change the values in script is the same as you would with other components, e.g:

ColorAdjustments c = gameObject.GetComponent<ColorAdjustments>();
c.contrast.value = 0.5f;

[shy thicket]

thanks

[severe slate]

using the unity post processing package, is there any way to prevent ambient occlusion from popping up through other objects? Or is this only visible in the editor?

[heavy hamlet]

Anyone know why my LUT wont work? URP version 2021.3.0f1

[gritty trout]

hello everyone, does someone know why my gun goes transparent when i activate ambient occlusion?

[night meteor]

Hey, I've made a telescope minigame that i'm testing. It works by having a separate camera look in a starry skybox, which is then applied to an ingame computer screen as a rendertexture. However, while ive turned off any anti aliasing on the telescopes camera, since I have TAA enabled on my Player camera which ultimately looks at the rendertexture, it makes the screen look EXTREMELY blurry and makes the stars pop out when rotating the telescope camera.

Is there anything I can do, except disallowing the use of TAA for my entire game?

[sterile iron]

looks like your gun is not rendering into the depth buffer
so the post effect SSAO does not know that its there and will just use the depth and normal information it has of the elements behind it

[cursive briar]

hey i'm trying to set up post processing on my camera but when i do ALL the steps nothing happens and i dont know what i did for post processing to not show up but i wanna know what i could have done wrong, or what could have gone wrong in general

[exotic oriole]

what steps would be a start

post processing exists differently depending on the render pipeline

[cursive briar]

i have urp

1. install pp
2. add a pp layer to camera and add a pp layer
3. make a new empty object and add a pp volume to it or add it to camera and set it to global

4. make the object pp or the camera if so

5. add effects

also make sure pp is checked on the camera

and i did all this and it no working

is there anything i should check???

[exotic oriole]

you install PP?

urp doesnt need to install anything

it already includes pp

u must be mixing legacy with urp

[cursive briar]

idk maybe

i know that

but i am trying to use pp because when i used bloom on the urp version it doesnt bloom

[exotic oriole]

go to Project Settings - > Graphics

screenshot

[cursive briar]

ok

gimme a sec

hello?

[cursive briar]

i screenshotted

[exotic oriole]

lol why didnt u just tag me earlier

Ok so ur on URP

[cursive briar]

i forgot to

ye

yes

[exotic oriole]

ok chill with vertical messages

now show the camera

and global volume @cursive briar

[cursive briar]

vignette in full

but nothing

[exotic oriole]

ur using the wrong PP

uninstall that and just use the URP volume

[exotic oriole]

removePostProcessing v3 package from package manager

[cursive briar]

but wait why?

[exotic oriole]

i really gotta repeat myself dont i

[cursive briar]

ok fine

[exotic oriole]

URP has its own Global Volume and PP..

that one u installed is only for Built In Renderer

which is legacy

[cursive briar]

thanks

[native pebble]

Hi ! I tried to use the post processing in Android.. and I have big FPS losses 😦

Do you know an another way to make a bloom effect ?

[severe vault]

@if it's 2d then you can just bake it into sprites/textures

[native pebble]

I found a solution in the Unity market, perfectly works on mobile : https://assetstore.unity.com/packages/vfx/shaders/fullscreen-camera-effects/fastmobilebloom-79310#description

[grizzled patio]

Hey! Does anyone know what the difference between _MainTex_TexelSize.zw and _ScreenParams.xy is when using a fullscreen shader for post-processing? From how I understand the two there should be no difference, however, it does make a difference depending on which one I use...

[halcyon trout]

Hello guys, girls etc !!
Is there a way to make blur on a specific part/object of a mesh ?

[native pebble]

I guess it's impossible with post processing

[halcyon trout]

Ok, so, ive to try something else. TY.

[mighty stump]

It's possible to make such a shader or a custom post process effect
Similar principle as how refractive shaders work, but blur instead of distortion

[toxic temple]

Hi all, I've just upgraded my project to 2021.3.8f1 and am trying to understand the Environment > Volume Mask setting in conjunction with camera stacking. I thought it would mean I could have separate PP stacks per camera, but it doesn't seem to work that way?

My current setup is Base camera on Volume Mask 1, Overlay Camera on Volume Mask 2

Base PP on Layer 1 (set at the top of the Inspector), and Overlay PP on Layer 2 (set at the top of the Inspector)

I thought it would work such that the camera on Volume Mask 1 would only be affected by the PP on Layer 1

And the same for Camera/PP on Layer 2

But the overlay PP is affecting both cameras

I know this question has been asked a million times but I can't seem to find a specific reason as to why this isn't working in my use case

[mighty stump]

They can use different post processing layers
However note that when the overlay's post processing acts on the overlay camera, the camera below has already been composited to it

Regardless of how many cameras you stack, every post process in the stack affects the full stacked image at that point in the stack, including all images below with their post processing

[severe slate]

post proccesing isnt working for me on hdrp

ive followed so many tutorials💀

[tall saffron]

As soon as you create an HDRP project several postprocessing effects are already globally active.

[severe slate]

figured it out

[ashen pebble]

wasnt there supposed to be ambient occlusion?

[mighty stump]

If you're working in URP, SSAO is a renderer feature, not a post processing effect

[ashen pebble]

i tried that but it didnt do anything

[mighty stump]

I can confirm it does something
Projects created from the URP template implement both post processing and SSAO so you can look there for examples

[ashen pebble]

does it work with the unity toon shader?

[mighty stump]

I assume so, considering it's rendered separately

[dark ermine]

When I apply Ambient Occlusion via the post processing package (built in renderer 2020.2.2f1) I get weird flickering on my leaves and grass + a strange band across the top of my screen. flickering is only visible when moving the camera

[somber trench]

in HDRP is it possible to use Amplify for fullscreen shaders? i wanna make a fullscreen custom pass shader for post processing effects but cant get it to work

[minor smelt]

[random forum]

There is a showcase section #archived-unitytips

[fresh cypress]

how can i make this outline effect? I tried some effects found on the internet, they work but the camera view becomes partially black

[minor smelt]

Too puch changes in terms of color or normal I suppose?

[fresh cypress]

I don't know, I'm new to unity and I don't even know if this effect is done with post processing

[minor smelt]

It is done in post peocessing
You should check alexander ameye tutorial 😉

[fresh cypress]

already tried it

[clever bolt]

Is it recommended to "reassign" blit materials in a custom render pass? from what i understand we can pass it in the constructor of the render pass, but in the first few frames of enabling the render feature the material is null in the render pass

unity's ssao implementation reapplies it every frame and sets its keywords every frame

but isnt that wasteful/using unnecessary resources?

[minor smelt]

I create my material in the pass constructor and I don't have any issue

[clever bolt]

what about setting the material values? where do you set it in, like in the constructor, onCameraSetup, Execute, etc.

[clever bolt]

I cant do this bc its a project constraint

[minor smelt]

In the constructor

[minor smelt]

Why can't you use the constructor?

You can still do it in onCameraSetup

[clever bolt]

No i mean i cant create materials in the constructor

artists want to be able to edit the values of the material on the material inspector

[clever bolt]

wouldnt it that be called every frame then?

onCameraSetup runs every frame for each rendering camera

[minor smelt]

Uhm I see 🤔

[minor smelt]

I should check but I think constructor is called whenever you change the renderer settings 🤔

[minor smelt]

Oh okey

[clever bolt]

yeah, but sometimes the render pass is created before the renderer feature has been unserialized

making the material null

[minor smelt]

Is it really seen? Like I never had this issue 🤔

[clever bolt]

one sec

[minor smelt]

Yeah okey but do you have something weird on screen by doing that?

You can still update the material OnValidate

[clever bolt]

its more of engineers screaming at me for leaving in errors

the pass works fine

[minor smelt]

Yeah I see ahah

[clever bolt]

but this is the optimization stage

and its really trying to squeeze as much as possible

bc the render pass is gameplay critical and its quite expensive

[minor smelt]

Yeah I see, I don't have that much idea for you 🤔

[clever bolt]

sadge

nvm then, thanks for the help

[bleak hazel]

Is there a way to prevent my PostProcessEffectRenderer from showing in the scene view? I see a context.isSceneView property which I could test against inside my Render function but simply returning from the function causes the scene view to become entirely black.

public override void Render(PostProcessRenderContext context)
{
    if (context.isSceneView) {
        return;
    }

    // Post-processing logic...

[junior bloom]

using hdr + bloom and i'm getting this "outline" effect on my ui elements

it looks decent close up, but from far away it looks like an antialias fail

is there a good way to resolve it?

[odd drift]

How are you making that part emissive?

[junior bloom]

the radial bar is actually generated using a lit shader graph (there's some other properties there to for it to dynamically segment), so im just using a hdr color to multiply to get the emission

[odd drift]

That could be the problem if you multiply the alpha channel too, otherwise i dont know

[late crow]

Hey guys, my post processing doesnt work on my scene

I know it may sound, weird, ive tried everything. This new version of pp i dont understand

Nvm dude.

I have to use URP built-in

instead

[glass mulch]

[SOLVED] Is anyone using URP 14 or higher? If so, on the Bloom Settings do you have available: Downscale and *Max Iterations *?

[thin axle]

I'm using the Depth of Field Post Process effect in URP. For some reason, there's a square in the bottom left corner that doesn't get blurred. Here's a screenshot:

[errant dragon]

@snow coyote regarding different post-processing per camera: in theory it should be possible, but at least with URP overlay cameras it’s not working. I solved it by rendering other camera to texture and then doing composition with custom post-processing effect.

[snow coyote]

Thank you for following up. Im using a render texture too, however im doing built-in

[proven burrow]

so

what's wrong with post processing in urp ?

[cobalt minnow]

Nothing

[proven burrow]

my bad i had to read docs about volume

[junior bloom]

https://media.discordapp.net/attachments/502171135350407168/1052550928538030121/image.png

antialiasing is causing my tmpro text to be funny

any idea how to fix this?

[surreal nymph]

hey so im having a problem in my whole game, i dont know why but all my post processing effects dont work. I just bought a retro vhs effect pack and that wont work either

none of my original effects are working

[cobalt minnow]

What pipeline are you using?

[surreal nymph]

URP

@cobalt minnow

idk why i created a new project with the asset in it, added post processing and urp and it all works

hello anyone?

[cobalt minnow]

URP comes with post processing built in. Did you install the post processing package from the package manager? Because that will cause issues.

[surreal nymph]

yes i did

ive watched like 5 videos now and nothings working

[cobalt minnow]

You need to not have that package in your project if you're using URP

[surreal nymph]

ok removed

still not seeing results

[cobalt minnow]

You also need to use the URP volume, make sure you have post processing turned on, on your camera.

[surreal nymph]

and about 38 of my scrips rely on post processing package

[cobalt minnow]

Start with using something built in like vignette

[surreal nymph]

there in the two effect packages i bought

[cobalt minnow]

Then you can't use URP or update them to work with the URP post processing volume.

Did you check that they were compatible with URP?

[surreal nymph]

ive been looking but there has been nothing said it can or cant be used

ive looked all in the project files, on the unity store page, found nothing

https://assetstore.unity.com/packages/vfx/shaders/fullscreen-camera-effects/vhs-effects-168471#reviews

thats the asset

[cobalt minnow]

If it doesn't specify, then it's most likely for built-in only.

[surreal nymph]

am i able to downgrade my project to built in?

[cobalt minnow]

You can remove URP yes. Something to look up because I'm not going to type it all out on mobile.

Though keep in mind, any URP features you're using will stop working too.

[surreal nymph]

got it, thanks

[surreal nymph]

ok still my post processing is not working

just in general

the package is out too im just staying in urp

but no pp is working

[cobalt minnow]

Is it turned on, on the camera?

[surreal nymph]

yes

[surreal nymph]

i dont know why no post processing works

[cobalt minnow]

Show your setup for it. Show that the built in package was removed.

[opal hemlock]

Hi, I have a question about post processing effects. In my game I have 2 cameras: 1 base cam to show pretty much everything, and 1 overlay to show a UI item (a weapon for example, so that it doesnt clip in walls etc). This UI camera is part of the base camera's stack. I use post processing effects on the main camera (bloom, tonemapper, shadows midtones highlights, vignette). I want those same effects on the UI camera, but when applying the same effects, it applies it to everything, as if I just doubled the intensity on the main camera for everything. Does anyone know a fix for this?

I also tried using a 2nd post processing volume settings object to disable some effects, but that just makes my UI camera show in colors that aren't exactly matching with the colors in the rest of the world. it looks off

[opal hemlock]

you can see here that the bloom from the sun works on the environment but not the hand (UI cam)

and when I disable/enable the tonemapper, it gets applied to everything. I want it to apply to just the hand, because tonemapping is already applied to the environment

i also made sure to use the right layers at the volume and culling masks. I put EVERYTHING EXCEPT the layer the hand is in at the main camera, and I put ONLY the hand in the UI camera

I want the effects to only apply to the hand. not the stuff that already has post processing

[opal hemlock]

Nevermind. Solved it by removing post processing from the main camera, and only applying it to the UI camera

[slim fox]

Helloo, So... I little trouble here.. I have two volumes, the volume A is global and the volume B is not, the volume B just works if it starts disabled and enable it after the Volume A... I create a Invoke to enable it after .2 seconds, works... but... Don't seems right... What can I do?

[mighty stump]

For future reference post processing always applies to every layer/camera below in the stack, due to their nature

[opal hemlock]

🫡

[deft sinew]

someone knows how to disable the postprocess on some of the objects? for example, I don’t want the glow to work on such an object

[mighty stump]

Post processing is always per whole rendered image
Your best bet is to use bloom threshold and control the brightness / emission intensity of materials to kind of choose which one of them goes above the bloom threshold

[deft sinew]

is it really possible to somehow make the same glow effect for a mesh but without post-processing?

[mighty stump]

Not the exact same but similar
Particles would be an option, soft particles especially

[deft sinew]

is it possible to lay particles along the mesh? I have a spline that generates a mesh

[mighty stump]

You can spawn particles using a mesh as the shape without any extra tricks

[deft sinew]

I cant use my spline mesh into this field

[mighty stump]

Then I'm not sure
If "mesh renderer" doesn't let it update automatically then you might have to assign the generated mesh through code

[deft sinew]

shader glow effect can be done somehow? maybe some useful links?

[mighty stump]

"Shader glow"? Either you render some transparent geometry that mimics a glow, old games often did with sprites or particles, or use post processing for it
It's also possible to render the glowy objects entirely separately, blur them and composite them along with post processing, but there's no system for that by default

only the simple full screen brightness based bloom

[surreal nymph]

hey so post processing isnt working in my first scene for some reason but in all my other scenes it works fine. i have pp checked on my camera and enabled so idk what it could be

nvm found the problem

[humble copper]

Does anyone use the Kino package by Keijiro? I'd need some help or any code examples, everything would be highly appreciated

[proper dust]

Hello, i need help with bloom. I have added bloom to the moon but it affects all objects and the skybox and i cant find any way to fix it. I have tried ading another camera that can only see the skybox and not bloom and disabled the main camera from seeing the skybox but now when i klick play the skybox is not visible at all.

[hexed nova]

what do your post process settings look like

[hexed nova]

yah, you see the threshold is at 1, which means anything is blooming

[proper dust]

Is my game broken or why wont this work at all?? I did exactly what this tutorieal told me to do and it still dosent work...

https://vionixstudio.com/2022/02/21/how-to-create-a-glow-effect-in-unity/

[hexed nova]

you need to use shaders to make things bloom seperately

[hexed nova]

idk

depends on a lot of things

that tutorial sucks btw

[proper dust]

I have tried 20 difrent tutorieals and nothing works...

[hexed nova]

what part doesn't work

[proper dust]

The glowing pare or making only 1 object glow part

Everytime eaither nothing glows at all or everything glows

[hexed nova]

i already told you why

#💥┃post-processing message

[proper dust]

Now it dosent want to glow at all

[hexed nova]

becuase you need a material with an emission property set

[hexed nova]

?

[proper dust]

Emission is on for the materieal

[hexed nova]

with how much intensity

?

[hexed nova]

so it's glowing

[proper dust]

Nope

https://cdn.discordapp.com/emojis/959026523854209064.gif?v=1&size=40

I have set the layer to a new oane named glow but it dosent work on the default oane eaither

[hexed nova]

idk then

wait actually you showed me the wrong intesity value

go back to the emission color and click on the color

you're suppowed to change the intesity of the color value

but you showed me the intensity of the post process property

[hexed nova]

if it isn't glowing then, idk

does ur camera have post porcess enabled

[proper dust]

Yes

I have no idea what the problem is and what it wants from me

Im going to make a test project and do the exact same thing to see if it works there

[proper dust]

It works there but afects the skybox

[mighty stump]

These are settings for an URP camera, but the tutorial is for Built-in Render Pipeline, which is probably why it didn't work

[mighty stump]

Post processing is per whole rendered image, so you cannot apply it selectively
The exception to that is that you're able to apply post processing on a rendered image before each additional image from overlay cameras is composited and in turn post processed

Doesn't really work for bloom because it needs to be applied last if you don't want the glow to be covered

[proper dust]

Does that mean i cant add bloom without making everything glow?

[mighty stump]

Yes, not without a custom system that does it selectively
You can use a high bloom and emission intensities to get a similar effect though

[proper dust]

emision only changes the color for some resone

[proper dust]

How can i get a custom sistem that selectivly does it

[mighty stump]

You could look for such assets on the store, or start learning how to do custom post processing effects using data from custom passes or extra cameras

[proper dust]

I have had more then enugh trail and error with this bad bloom sisten so if there is a asset for that it would be grate.

[mighty stump]

Maybe there is

[visual hull]

should it really take about 6 (went up to 9) hours to bake this small room with 1 single light?
im baking on my rtx 3060ti

[mighty stump]

This is a #archived-lighting question
Showing your lightmapper settings may offer some clue

[visual hull]

oh ok, ill take it over there

[delicate blaze]

How do I make an effect like this?

[odd drift]

I think thats just inverted color so 1 - thePixelColor (subtract the pixels color from 1 separately for each component). You can make your own post processing shader to do that or try to find one from online

[blissful badge]

does anyone know which Version of Post Processing this Component belongs to?

[marsh frigate]

URP or HDRP

[blissful badge]

ohhhh that makes sense now, thank you!

[blissful badge]

I noticed Bloom effects override each other, is there a way to give local bloom effects a radius?

I know we can change the Blend Distance but that only seems to affect the difference between cameras that get near the object

[mighty stump]

Post processing overrides are always per-camera, never per-object

[blissful badge]

so bloom is how the camera sees each object?
when I place 2 different bloom objects one above another both bloom gets to both objects.

Is there any way to avoid this?

[mighty stump]

"bloom objects"?

[blissful badge]

different game objects with the volume component that has a local Bloom effect.

[mighty stump]

The camera gets its post processing settings based on its position and distance relative to volumes
The bloom itself is not "local" and never will be

[blissful badge]

That explains so much, Thank you!

[obsidian nebula]

Hi, im experiencing a bug when i try to build my game. The build fails to be created and gives the following errors:

It says something about a Bee Post processor

Even though i have post processing off for my urp module

could anyone please help me fix this error?

[mighty stump]

It's not related to graphical post processing at all

[obsidian nebula]

do you know what it could be related to?

[ruby bane]

How do I add an exposure override to a volume in Unity 2021.3.16f1? All the tutorials I'm looking at seem to be using earlier versions and say to just click on "Add Override" in the Inspector, but I don't have that option. I tried searching for "Exposure" in the 'Add Component' list for the volume, but came up with no results, so I don't think that's what is meant...

[hushed ivy]

On HDRP you can add a Volume > Global Volume, then in that Volume component you click the 'Add Override' and find Exposure. On URP, it looks like the exposure is in the Colour Adjustments override.

[ruby bane]

Ah, thank you! I believe I've got it

[visual hull]

what am i missing to see how much these lights actually glow?

when i play test they glow very much, making it hard to see what im doing

[rough birch]

how do u add chromatic abberation to only specific objects?

[restive oyster]

is there a way via script to change Depth Of Field distance on a volume ?

[verbal hemlock]

So what’s post processing do for 2D games

[cobalt minnow]

The same it does for 3D games, adds screen based effects.

[odd drift]

Takes the resulting image and processes it in some way before showing it on the screen (like osteel said). The behaviour is exactly the same no matter how the frame is rendered, altough some effects like depth of field or screen space reflections relies on things like depth texture which doesnt usually exist on 2d games

[verbal hemlock]

Alright thanks was just wondering cause I was thinking about adding some screen based effects to 2D games

[restive oyster]

how can i change Volume profile in runtime via script ?

Or even simpler, how can i activate/deactivate a post process effect via script ?

[tall saffron]

enable/disable the volume or set its weight

[restive oyster]

sure, but i don't find how to do it in script, there's no doc about it and no result on the forum search

[tall saffron]

wdym there's plenty of docs about it

it's a component like any other too, so enable/disable works as normal

of course which component we're talking about depends on which postprocessing framework you are using (which depends on which RP)

[restive oyster]

didn't found the docs then

[restive oyster]

URP post process

i mean i found docs about it but not about the scripting part

and if i click on the "?" in Unity inspector it redirect me to an inexistant web page

[tall saffron]

it's just called a Volume

[restive oyster]

...

[hexed nova]

the post process component is a volume from unityengine.rendering
and each different post process has it's own class
like colorcurves, bloom, etc
so you put a field for volume, and whatever post process you want in your script and do

        {
            ColCurves = colcurves;
        }```

to get the post process reference into your post process field

you can't drag and drop individual post processes unfortunately

you can only drag and drop volume as a reference in inspector

[restive oyster]

thank you so much for all the explanations, will try that

[hexed nova]

yeah, it's not very well documented, if you try googling you mostly get questions as results lol, had to dig through youtube to find anything

[restive oyster]

lol yeah, i was becoming crazy not founding any documentation so i ended up posting here, it's strange because everything else is very well documented

[autumn temple]

Hm, I'm playing around with the depth of field post-processing volume and have tried both the Gaussian and the Bokeh methods. However, it seems like each effect either fully applies to an object or does not apply at all

Is the "distance to the object" etc given by the distance to the center of the object, and not the distance to that particular pixel on the object?

The object top left is very close to the camera and the two objects near the bottom are further away

yet they all appear equally blurred no matter how much I fiddle with the settings

[odd drift]

Depth buffer, which as far as I know dof uses, stores the distances to each pixel, not the object origin, that much I can tell atleast, its really hard to say why that problem would happen other than the settings being wrong

[autumn temple]

Well, at this point I'm looking at this

Moving the camera away or towards the objects does not appear to change the amount of blur, no matter what the setting is

IE even if I twiddle with the FocusDistance so that the objects are barely perfectly in focus, moving the camera significantly away from the objects afterwards does not make them blurred again

Do I have to configure the depth buffer in any way myself?

[odd drift]

Maybe? Im not sure. It also depends on the render pipeline

Btw if thats 2d game, you better forget the idea of dof

[autumn temple]

It's a "2d project" but the camera is perspective

does the project type matter?

I'm in the Universal Render Pipeline

Although, that is not an effect applied to the camera through a post processing layer, it's a "volume profile"

[autumn temple]

Effects added through "Post processing layers" and "Post processing volumes" appear not to trigger at all, only effects added through the "volume profile" seem to occur.

[mighty stump]

Make sure you aren't trying to use use Post Processing Stack v2 components with URP

[autumn temple]

Does that mean I can't use the "Post-processing layer" and "Post-processing volume" components with URP?

[mighty stump]

Correct

[autumn temple]

I see

However, using only the "Volumes" method, my issue still persists

Could this be due to a setting that is set when I make a 2d project?

[mighty stump]

Is it using a 2D renderer?

[autumn temple]

without being 100% sure

Yes?

[mighty stump]

DoF is a 3D effect while the 2D renderer doesn't handle 3D at all
I would assume it doesn't even produce a depth buffer

[mighty stump]

i.e.

[autumn temple]

But..

Well

switching to a 3d renderer appears to have solved the issue

Thanks!

[mighty stump]

Another thing that I see causing issues with DoF and sprites is that DoF doesn't really work with transparency
You might have to change the sprites shaders to be opaque with alpha clipping instead down the line, though I'm not sure

[autumn temple]

Although

My 3 blocks are now properly blurred depending on their distance to the screen

but my 1 large object blurs as one large thing

instead of blurring based on pixel distance..

[open gulch]

I have a lookup texture which is purely black and white. However, unity thinks that it has two extra greys which I really dont want, how do I fix this?

[marsh frigate]

set the texture to point sampling and not billinear

[open gulch]

it is set to point, but this still happens

[marsh frigate]

Then either something is wrong with your texture, or your logic

make sure compression is disabled on your texture too

[open gulch]

nothing is wrong with the texture, I believe

[glass mulch]

Hi, I have a post-processing error on android, it can't be seen on the pc build nor the editor using Unity [2022.2.1].

I already introduced it on the ui-ux channel, but I now figured out it was postprocessing

I created a test on my project and saw how enabling post processing mid execution created a sort of static frame and it constantly switched between the static frame and the real one.

After 2 seconds I enable post processing, I think you will be able to notice it though😂

The flickering issue is fixed when I go to the home screen without closing the app, and reopen it.

[glass mulch]

Ok, I tried many things, basically I focused on clearing the buffer, setting clearflags...

The "quick fix" or solution by now is updating the resolution to a different size, and reset it back to its normal resolution.

It would be nice to know which calls are made when changing the resolution.

[soft garden]

Please how can I use Post processing in URP without thanking performance, I only want bloom but this drop FPS by 10 on low end mobile

[restive oyster]

Interested to know too

[mighty stump]

@soft garden @restive oyster Bloom is inherently expensive on mobile hardware
You can search for mobile optimized bloom assets on the store which I've heard work okay, but I haven't tried them myself

[restive oyster]

Alright thank you

[mighty stump]

I think newer versions of URP have an option to skip iterations which would make it cheaper

[restive oyster]

yeah i think i've seen something like that in the parameters option

[soft garden]

it improves performances alot but still not enough for low end devices, do you guys have any idea how i can make something glow without post processing, closet I can get is with frenel effect

[weary delta]

Is it possible to apply Post Processing to an area in Unity 2D URP?

[mighty stump]

Post processing from volumes applies to cameras, not areas

[weary delta]

yes, during my research found that might be a better idea to use a shader, trying to find or create one right now 🙂 Shader language is sadly hard though, don't understand things.

[weary delta]

failing though. do you per chance know a working grayscale shader that acts like a mask with an effect?

[mighty stump]

I tend to make my own shaders so I don't know of pre-existing ones
Desaturating in fragment shader based on some external factor is a simple color operation
Having that external factor be localized in the scene is trickier and there's many ways to go about it depending on how it needs to work

[weary delta]

yes, its a simple color operation, and I now know that there are some formulas to do so, but that just gives me a grayscaled sprite, sadly.
How it needs to work -> I have an image which allows me to paint areas(not sprites though) in grayscale.
Tried both masks and textures, nothing seems to work.

directly put something on scene which I cannot see, but it paints the area beneath in grayscale

[mighty stump]

There's many way to make a dynamic "paint" effect
The most common one is to draw on a render target texture
You would then sample that RT texture in the shader as a factor for the greyscale effect

[weary delta]

I'm sorry for putting my words wrong, what I meant by painting is not in game drawing, but -> I put something, let it be a raw image + texture combination, image with mask or just sprite, anything basically which has geometry bounds I can control, in my scene, so that I don't see what I put, but rather what is under it, the sprites, in grayscale.

[mighty stump]

Sure, those are all options

[weary delta]

and all of them tried, and all of them failed.

[weary delta]

the best result I achieved is finding a blur shader which works with world space canvas, but converting it to grayscale failed also. I can link my shader code if you have time.

[mighty stump]

You could present the question in #archived-shaders

[plush pumice]

Fake it

Use lens flares

Not the new kind, the old lens flare system

[mighty stump]

Or just glow sprites in general

[plush pumice]

Or if that doesnt work then use glow sprites

Beat me to the punch...

😛

[mighty stump]

"Faking it" should usually be the first option to consider ^^

[plush pumice]

Transparencies on mobile can be expensive, but should be less than the cost of a fullscreen bloom

[quaint flume]

From what I could understand, maybe you want to stencil out the areas you want to blur and greyscale and keep the rest of the areas unaffected. Or create a mask in a separate pass and write it to a RenderTexture. Use this as a mask in the final post-processing effect...

[weary delta]

Interesting! But all I needed was _CameraSortingLayerTexture and this example: https://github.com/Unity-Technologies/2d-renderer-samples/tree/21.2/Assets/Samples/2D Renderer/02 Applied Samples/Heat Haze Overlay

[quaint flume]

ohh okay, you're doing heat haze effect. Cools 🙂

[weary delta]

No-no, I'm doing grayscale :) needed to somehow get the scene color node alternative in 2d, which as I now know is _CameraSortingLayerTexture

Now I can apply grayscale to parts of the screen as an overlay

[quaint flume]

thats nice! quite interesting, I've not yet worked on 2d platforms. But this is useful piece of information for sure 🙂

[cobalt folio]

would anyone have any insights on how to get a blur effect similar to this?
https://youtu.be/lH6qlF_iegU?t=839

[neat ledge]

Anyone know how to have URP post processing not apply on worldspace canvas?

Seems like URP PP Volume is all or nothing deal.

So I tried to Camera stack - one for gameplay with post processing as base, another camera for UI including WorldSpace UI as overlay camera in the stack with post processing disabled. But Camera stacking seems to be incompatible with WorldSpace UI since it follows the stacked UI camera instead of respecting its world position.

I'm on Unity 2021.3.16 and URP 12.1.8

[neat ledge]

Solved by applying same changes to the UI Camera as the main camera, position, orthographic size and everything else has to match.

[thick shadow]

Any ideas on why Post Processing is working in the Game View but not the Scene View? I have it turned on in the Scene Effects options.

[neat ledge]

URP? There's a post processing checkbox on the Camera, enable that.

oh, sorry, working in game but not scene view, can't help with that.

[thick shadow]

Yeah it's the opposite of the usual problem 😛

[tired gull]

Anyone know why bloom is triggering here'

For context I imported a model and it just started blooming on the edges here, using unity toon shader if that's any help

Apparently it's these faces here

[mighty stump]

@tired gull This happens if the shader is producing nonsensical values at some point
Probably something crazy high or not-a-number

[tired gull]

Moved around some vertices and it doesn't do that now, but damn that was weird

[devout bronze]

does my canvas need to be screen space camera for UI to be affected by PP? urp project if it makes a difference

[mighty stump]

Screen space - camera or world space

[devout bronze]

im having some issues with it. I set up a UI camera, set the culling mask to UI only, and on the main camera unchcked UI. my canvas is set to screen space camera, with the UI camera dragged in as the render camera. I can see my UI, but it doesnt seem affected by PP (PP is checked on the UI cam). the UI cam's render type is set to Overlay, and I added the UI cam to the stack of the main camera. did I forget a step or do something wrong?

edit: actually its kind of working, i jacked the bloom up and can see changes in one of the elements. but the TMP text is unaffected still, and it's set to UI layer

[mighty stump]

Do you just want PP for canvas, or is there another reason to use an overlay camera?

[devout bronze]

PP for the canvas is my goal

[mighty stump]

In that case you should need just one camera and nothing to do with culling masks
Canvases rendered by a camera should also get post processing if the canvas is not screen space - overlay

[devout bronze]

ill change it back then, but any idea why the text is unaffected by bloom? that was what i really wanted

[mighty stump]

Haven't had that happen
Remember to assign a Render Camera to the canvas

[devout bronze]

oh it was an issue with that specific font, glow works with another. i guess last question I have is how do I create different PP profiles so I can have one set of settings for the UI and the other for the game? i recall how to do it in the basic render pipeline but URP seems different

[devout bronze]

is there any way to create different volumes based on layer in URP like with built in? the only choices im seeing are global and local which uses colliders?

i dont know if this is the right way to do it but it worked for me, just made local volumes and parented them to the cameras. the gameplay one to the main camera and the UI one to the UI camera. seems to be what I want

[mighty stump]

The volumes use the gameobject's layers, camera uses "volume mask"

Parenting local volumes to cameras is redundant unless you plan to move them somewhere at some point

[severe slate]

Hi.
I have a small probem and I think it's due to my post procession to my scene:

whenever I try to add antianalysing to the camera, when I click play I see a black screen

Any idea what is happening

[mighty stump]

What type of AA component is this? It looks like a custom system

[proven burrow]

any tips for a blue that dont hurt the eyes ?

and does this looks okay (it will appear only for few seconds , less than 10 i guess)

[mighty stump]

What do you mean by "hurt"?
The image looks mostly grey to me

[severe slate]

look like blur

[south spindle]

Anybody know where I drag a .shadergraph in the editor so it runs as postprocess on the whole screen?

[south spindle]

In the right click menu, I managed to create this asset. But I would expect there would be a plus button in this inspector to add a shader graph effect. Is this not the right asset?

Found that under Create > Rendering > Universal Render Pipeline > Post-process Data

I'm getting somewhere! Chat GPT told me I need the Post-processing Profile, not the Post-Process Data.

[south spindle]

Trouble I'm having is there is no "Shader Graph" option in the dropdown and I have the latest shader graph and post processing stacks and a unity version later than 2018.3 so I am stuck.

[proven burrow]

can i decreases the value of a post process profile (Volume since im in URP) in the runtime ? i want it to start with a blue and it gets clears after few seconds , or should i use a different thing ?

[sterile iron]

Why would you expect a shaderGrpah Option there?

[proven burrow]

Is it possible to control post process values using timeline

[south spindle]

Because you can use shadergraph as a fullscreen post processor. I got it working yesterday by adding a Full Screen Pass Renderer Feature component to my UniversalRenderPipelineAsset_Renderer, Right clicking to create a "Fullscreen Shader Graph" and material, then dragging the material into the Pass Material of that component. Thank you for your help.

[sterile iron]

good that you got it working that way
the options lieted for the post processing are more then just a material / shader but a script that handels the effect
that would need to be written your self if you want to go that way

[south spindle]

I finished an edge detection post processor with shader graph and no written code!

[sterile iron]

via the Renderer Feature you can
if you want to use the post processing system you cant
you need some code around to setup your post process

[south spindle]

I really don't mean to get into an argument, but I literally did it as I described with no scripting. I know shader graph converts into shader code under the hood and maybe this is how everything checks out for you.

[sterile iron]

the post processing system and the Renderer Feature
they both can use the shadergraph shader that you created (correctly without any code)
but if you wan to use it in the post processing system (that the one you showed in the first screenshot where you shadergraph option was missing ) you would need to create some sripts to make your custom effect show up there.

i know you got it working and if that's how you want it its fine 🙂

[south spindle]

Alright, I see what you mean. Have a nice day!

[mighty stump]

I think specifically only the newest versions of URP added the option to plug in a shader graph as a post processing override

[ruby coral]

unity hdrp depth of field is it posable to set a target

[jade marlin]

if you can change the depth of field values in runtime, just get a distance to target from cam, and set value?

[normal geode]

Hi! I'm upgrading a webgl project from Unity 2020.3.38f1 to Unity 2022.2.1f1...

I'm getting the following error in 2022.2.1f1 (works fine in 2020.3.38f1).

I see this posted in forums and here in the discord but I don't see any answers. I haven't swapped out my GPU in the past 24 hours so I'm confident that is not the issue.

I do see post processing in the error, which we have in the project (v3.2.2 which should be the latest). We're using the built in pipeline

I do see those specific hidden shaders referenced here: https://docs.unity3d.com/Packages/com.unity.postprocessing@3.2/manual/Debugging-Post-processing-effects.html

Not sure if I'm missing a setting or need to add them to the "Always Included Shaders" possibly? Bit of a mystery...

[normal geode]

Might be helpful:

[meager sable]

Will custom post-processing work in built-in render pipeline in 2021 Unity?

[mighty stump]

Each render pipeline has its own way to implement custom PP, which aren't automatically compatible with each other

[snow coyote]

Hi! Could someone explain to me how Bloom works with URP PostProcessing?

I have two shaders, one is custom, and the other one is the Lit URP that comes built in

However they have a Bloom effect even when emissive is disabled

This is with Threshold 0.56 and Intensity 2

Then if i have Threshold 1.1 and 5 Intensity, white blooms very lightly.

Im after a more defined bloom thats not so faded, and also avoid bloom for these objects that dont have emission active. (This bloom seems to be because of the main directional light)

[gritty folio]

Bloom affects any part of the image that is bright / has pixel values over the threshold. Whether the shader is "Emissive" would only be important for global illumination.

When I use bloom I tend to have HDR enabled (on URP asset), a Threshold higher than 1, and have shaders output a high intensity value (by multiplying the output to increase values above 1, or use a HDR Color)

[snow coyote]

Im setting the Intensity to 10 (for testing) on the shader, and i get the object visible with no main light, however the bloom is not visible around it with a 1.1 threshold

[gritty folio]

Make sure you have HDR enabled on the URP asset or the camera colour target will clamp values to 1

[snow coyote]

Okay, thank you for the tips Cyan

[modest hamlet]

How would I go about create this post processing effect on unity?

[stuck cape]

I have text that is supposed to be shown on a screen. the only issue is I was hoping I could apply a fisheye filter to the test to simulate the rounded screen. how could I do this??

[mighty stump]

Start by studying the kind of techniques that are used for these
https://alexanderameye.github.io/notes/rendering-outlines/

[open gulch]

You might need to pass the screen through a shader graph using a fullscreen blit, if you're able to do that you can pass the screen through a spherize node

[fiery hare]

Hey , I wanted to ask , how can you change the values of things like bloom , chromatic abberation and other post processing stuff via code , Thank you in Advance ^^

[sweet atlas]

@fiery hare grab the volume component, declare a Bloom volume component then...
if (vol.profile.TryGet<Bloom>(out var tempBloom) )
{
bloom = tempBloom;
}
bloom.intensity.value, bloom.tint.value and so on..

[fiery hare]

Thanks a lot ^^

[sweet atlas]

I feel my question straddles #archived-urp and this channel.
I'm using a camera render texture to stream the scene. All good there, but UV's are flipped.
Flipping them in blit, no big deal.
Enabling post processing flips the image again - even when the blit is disabled ( or removing the flip in the blit)
I was thinking that the blit renderpass event was not in the correct order, so I put it all the way out ( after RenderPostProcessing.) Any clue from the wise devs here ? 😉

[zenith skiff]

I need some help with lighting in my game. I want a bloom effect on things that are in the background, but not everything in the scene. I added the global volume into the scene, and the bloom really shows. But everything then get's it. I have now looked around for a solution to this, but can't seem to find it. Some says that you need two cameras, 1 for what will render the bloom/post-processing and one for what will not. I don't get this to work. Does anyone here know of anything around this? Would really like the help I could get.

[mighty stump]

Your instructions are correct
If you're on URP you need to use the camera stacking feature to let cameras draw on one another

[zenith skiff]

But i dont get it to work

[zenith skiff]

I got it to seperate the bloom effect now of different objects. But the camera does not wanna show the objects that are not affected by it.

[mighty stump]

Try to get two cameras layered on screen first, then figure out how to make bloom affect only the layer below

[zenith skiff]

This is what I got so far

[warm ginkgo]

im making lights for the first time and why my light is behind background and how can i change that

[mighty stump]

More of a #archived-lighting question or #🖼️┃2d-tools question if you're working with sprite renderers
Sprite renderers will be unaffected by anything except 2D lights from URP's 2D renderer
Area lights specifically can't be used in realtime at all, unless you're in HDRP

[hardy lagoon]

I've switched from 3d to urp and my post processing doesn't work anymore does anyone know how to fix this?

[mighty stump]

URP uses different post processing entirely
Instructions in pinned messages

[hardy lagoon]

I've already fixed this but thanks

[north delta]

Any update from the community on this? It’s been a blocker for us since we upgraded Unity

[glacial pulsar]

Hey! I'm not exactly sure how to search for this problem on google so here I am.

As shown in the pictures, I have a line renderer that points to the direction the player will fling to.
The problem then comes when I enabled depth of field and then the blurry effect goes ham when there's nothing directly behind both the player and the line renderer, giving a very distinct cut off as shown in the first 2 pictures.

I am using URP and it's global volume as shown in the last picture.
If anyone can shed some light (lol) on it, it would be greatly appreciated. Thank you.

[soft dirge]

Is there any way to edit the color grading with an animation? Because I'm trying to make it so whenever you die, the color in the scene fades to black and white. Just like in Dark Souls.

[severe slate]

anyone know what post processing brackeys used in the rpg tutorial?

[steel magnet]

how to do dof on isometric camera in urp?

The render pipeline doesn't matter. Set the camera to orthographic and the Y rotation to 45.

[final pebble]

Hi, why might I be getting GPU errors when using AsyncGPUReadback.RequestIntoNativeArray() on a render texture, specifically a custom render texture?

[drowsy kernel]

maybe the render texture was temporary and the data on the GPU is dead?

[final pebble]

I didn't use CreateTemporary(), I just constructed a new custom render texture.

[drowsy kernel]

what error are you getting?

[final pebble]

It's a gpu error so IDK, but if I stop the function from returning I think it says something else, lemme check real quick

Right now it's saying not enough data provided when I try to LoadRawTextureData()

Yes i already have the camera setup but im asking how to do the depth of field effect on the isometric camera that doesnt blur the character but only the enviroment

[magic pasture]

Hello, i have problems with the Bloom on a Emission Material, since the emission from a .FBX import doesn't work(Or maybe i don't know how to do it, would be a question too) , i made a new Material, that has now Emission enabled. I also have PostProcessing(Downloaded the Package and made the Bloom Component). The PostProcessing in the Scene Visuals is also active, in the Game view it is the same(No Bloom). I also have HDR Enabled. Now what did i do wrong? (And yes i researched definitely about this on google, and didn't found anything except the things i wrote above)

I am using the Build-in render

[odd drift]

Doesnt sound pp related at all, #💻┃unity-talk would be much better channel

[coral lantern]

hi

[magic pasture]

Anyone can please help?

[mighty stump]

@magic pasture Did you follow the instructions in pinned messages for setting up bloom for built-in RP?

The screenshot of your volume looks like it's URP post processing, not built-in

built-in PP from the post processing stack looks like this

[magic pasture]

Yeah tried out after i wrote, forgot to mention sorry, but it didn't made any change

[mighty stump]

Are you using the correct components now at least?

Should give it more chance of working

[magic pasture]

Yeah, i followed the instructions on the post-processing and bloom from the docs/ liked from the troubleshooting link in the pinned message

[magic pasture]

Here, that's the post-processing i have rn.

Here the Material if it is needed, Emission is on (Also we can see it, that the World is dark)

And to the layers, the Object is in the same layer as the PP layer

[mighty magnet]

any ideea?

[clear verge]

I need help with post processing, I made it but it wont display on my camera

[plush pumice]

is there a post process layer component on your camera?

are you using URP or built in pipeline?

[clear verge]

I was able to figure it out

[verbal pawn]

Quick question, does anyone know why my global volume isn't being applied to my object when I actually run the game?

Nvm, Post-Processing wasn't on.

😄

[mighty stump]

To avoid future confusion note that post processing doesn't apply to objects, it applies to cameras ^^

[cedar forum]

guys I can't get post processing to work
I cannot do it
I added volumes, profiles, ticked boxes, everything
it doesn't work for me
how this works changes every month
so all tutorials are outdated

[bronze mural]

Follow the pinned documentation (top right) it explains in detail how to make it work. Also make sure you are using correct version. For Example URP comes with it built-in and default render pipeline requires package.

[cedar forum]

well I just checked it out

and I did all of that

[bronze mural]

Did you enable post processing on the camera? If this is indeed URP

[cedar forum]

yes

[bronze mural]

also you are not using threshold

That's the main trigger for the bloom

[cedar forum]

I clicked it and increased to 115

don't notice it

I also added film grain just to make sure and I don't see that either

[bronze mural]

other way

[cedar forum]

what do you mean

[bronze mural]

lower the threshold easier it reacts to brightness

[cedar forum]

also, I can disable pp volume and pp layer that I was adding? Those are ancient as far as I understand, right?

[bronze mural]

<1 range is usually sub HDR

[cedar forum]

nope, threshold 0 doesn't do anything either

I found something about switching to v2 in project settings but I can't find that anywhere...must be outdated too

[bronze mural]

Go over all of the steps in quick start in the manual make sure you are not missing something. Could create a clean scene as well for testing.

V2 is a package for default pipeline. If you installed it you might want to remove it

[cedar forum]

I installed this

[bronze mural]

#💥┃post-processing message

For Example URP comes with it built-in and default render pipeline requires package.

[cedar forum]

oh ok

so I'll delete the package

still doesn't work tho :/

I hate unity sometimes

[bronze mural]

Again, make a clean scene and follow the guide to not repeat mistakes.

Make that work then compare with what you have in the old one and fix it.

[cedar forum]

ok

all I wanted was to test screen space reflections

I will attempt to fix it

OK I fixed it

fkn bullshit

wait a minute

does urp not have screen space reflections?

[mighty stump]

Not without custom assets

[mighty stump]

Isn't this bloom right here?

[cedar forum]

All of that for nothing

[cedar forum]

umm actually I had to fix my character's glowing eyes and I rmemeber having to add bloom for that

but I don't remember anything about that, it was some time ago

in any case, I fixed it

following outdated tutorials (or simply tutorials for different pipelines), I made the camera on another layer...when I selected default, it worked

[lethal drum]

anyone know how to set the center of a vignetter via script?

[lethal drum]

figured it out nvm

[silk vale]

Has anyone ever had a problem with the post processing not working on a final build. If so do you know how to fix it?

[mighty stump]

Build on what platform? First thing to check if the default quality tier for that build supperts PP and has it enabled

[polar forge]

Hello. I want to maks my custom post processing effect. From what I have heared you can Inherit from a class called CustomPostProcessEffect which is supposed to be located in the UnityEngine.Rendering.Universal namespace. This class does not exist for me. Is this an outdated feature or am I doing something wrong?

[clear cobalt]

how do i get chromatic aberration on my whole screen? not just the edges. also without blur preferably

[mighty stump]

You'd make a custom effect that splits the color channels, offsets them in different directions and adds them back together, assuming that's the kind of effect you're imagining

[clear cobalt]

well, where is a good tutorial on that

[mighty stump]

I don't know of one
If there isn't one specifically like that, you'd have to find more general examples of how to implement custom post processing in your project's render pipeline, and then study how to make shaders that work with it for the effect

[clear cobalt]

ok will do

[tawny gulch]

why cant I see my post processing stuff

i followed a tutorial

I added a post processing layer

Its on my camera

I created an empt object with all the post processing stuff

[round lily]

Show your camera settings

[round lily]

Ok yeah I didn't know if camera had post processing setting was for other render pipeline than urp but what I would recommend is check your quality settings (I think there is a post processing settong there)

[tawny gulch]

I don't see a post processing option in quality settings

[round lily]

What render pipeline are you using

I know urp has some post processing settings

[tawny gulch]

It says none

[round lily]

That menas your probably using built in render pipeline

I gtg I'll try to help more later

[tawny gulch]

How do i change that?

Oh ok

[round lily]

You don't need to

[tawny gulch]

So what should i do?

[round lily]

I'll help ltr

I gtg

[tawny gulch]

I fixed it

Thanks

There was a setting I missed in quality

Thx

I have another problem tho

My materials on my gun on different than my materials I have in my materials folder

[round lily]

How is that an issue?

[tawny gulch]

Its way darker

[round lily]

Are you sure its not just lighting

[tawny gulch]

Yes

The icon the materials show are different

In the assets place

[mighty stump]

Not really a post processing issue

[round lily]

Just set the gun material to the one in the folder

[round lily]

Agreed, @tawny gulch Lets bring this to #💻┃unity-talk

[tawny gulch]

Yea I just didnt know hwhere to put it

[inland charm]

This is how my post processing/Camera itself is set up but it doesnt work

this is the Render Pipeline

[mighty stump]

Incorrect post processing component
URP uses the volume component, not the components from Post Processing Stack V2
Check out URP specific instructions in pinned messages

[modest hemlock]

how do i get it to affect ui?

im using urp

[blissful hull]

I haven't used post processing with cinemachine yet. Am I supposed to add my Volume component to it somewhere to get the effects to show in my scene view? Or what else could I have missed?

[mighty stump]

This one is pretty important

[blissful hull]

LOL

I'm so disappointed

Thanks Spazi, I'll change that when I wake up tmrw :p

[mighty stump]

Cinemachine itself doesn't need to interact with post processing, post processing is applied based on true camera position as you'd expect ^^

[blazing portal]

hey, im having this issue, the only fix i've found is turning off the bloom, or disabling "allow HDR" in the camera (which also turns off the bloom). This only happens on objects that are using double sided shaders. i've also attached the post processing settings

[jolly plover]

Anyone using the Post process v3 voumes for URP?
the v2 post processing doesnt seem to work with URP

[jolly plover]

Actually i figured it out myself but literally every example i found on the internet did it wrong (they were outdated due to changes in the API)

[mighty stump]

There are always up to date guides on this channel's pinned messages
I've never heard of a PPSv3

[jolly plover]

Apparently it's the new way that URP handles post processing in Unity 2022.1+
It's similar to how the other post process stack works.

[mighty stump]

Perhaps you're referring to URP's Volume framework

[jolly plover]

yes

[jolly plover]

is it possible to pass an object's layer as a texture for processing?
I want to only run an effect on renderers on a certain layer

Similar to an ObjectID pass but for the Layer data

[mighty stump]

No
The exceptions to this are camera stacking to render objects after executing post processing on the initial image
Or to produce a custom system that renders and post-processes images separately and then composits them

The default post processing is per rendered image, full screen effects only

[jolly plover]

Dang. Post processing doesnt work as well with a camera stack because they I end up renderering everything twice, or else i get the effect appearing on top of everything else

[mighty stump]

It works according to limitations of both systems
Mainly that since post processing is per image, each post processing effect applies to each rendered image under it in the stack

[jolly plover]

Right. But you can choose the time which the effect renders, so technically the post processing effect doesnt even need to be during the post-processing pass

Hmmm. Actually I have an idea.
A custom RenderFeature that applies an override material, but only for those with a specific layer mask. Then have the effect check for the override shader property and only draw the effect there

[jolly plover]

RenderFeatures can't get information on any object with the override materials, so what I would have to do is add is add a separate rendering pass with an override material that writes to a custom RenderTex, then have the RenderFeature check for that RenderTex

Man. all this just for a decent outline that doesn't appear through walls

[mighty stump]

There's many ways to implement outlines
I'd first look at examples of how others have done it rather than trying to bend the existing post processing effects to do it as the first option

[jolly plover]

I already know you can use an override material and blow up the vertex position for a screenspace outline. The problem is that method relies on the object's normals, which can be messed up for objects with sharp edges or concave surfaces.

Screenspace outlines use sobel filtering and always provide a smooth outline on the target, which is what I want.

The drawback is that screenspace outlines generally have to poll the camera's depth pass to determine when objects are far apart so it can draw the outline, and that happens for every object. since I only want some objects to be outlined I would have to add a separate camera that only rendered objects I wanted the outline for, and render that. but that uses a second camera on top

[mighty stump]

sorry for assuming you were jumping right into it without research
As long as you know what you're dealing with then it's a valid path

[blazing portal]

updating to unity 2021 didnt seem to fix it, though i didnt think it would

[silk oasis]

I have a bug that a custom post process effect disables the whole post processing in the build, does anyone know how to fix it

[tawny gulch]

what are the best settings for realistic look using urp?

[tawny gulch]

for some reason

my post processing keeps turning off randomly

[quasi forge]

Is there a way to blur a foreground layer using post processing in URP? I've tried camera stacking and depth of field, but it resulted in the whole foreground camera layer blurring, and not just the gameobjects on that layer, so any player and background layers were also blurred.

[idle swan]

Render them to a separate buffer (render texture) apply blur to that as a post processing effect, then compose the finished texture over your base camera output in its post processing pass. This will involve custom shaders & render passes.

[languid ingot]

which post processing effect is boxblur?

[last coral]

When I install post processing package in a fresh 2021.3.15 project it just endlessly sticks on reloading script assemblies. Trying to restart the project it hangs on the same thing indefinitely, preventing me from loading the project. I've tried to re-create the project and reinstall the package 3 times now with the same result. Is there something I'm doing wrong?

[mighty stump]

When post processing stacked cameras the order is crucial
A post process effect will affect the camera it's applied to, and always every camera rendered before that

[polar forge]

I have tried to usr the post processing V2 package for unity 2021 URP. I have setup the Post-Process layer on the camera and the I made sure that the volyme and is on the correct layer. But nothing happens when I add post processing effects to the volyme. Its like its not even there. Any ideas why?

[mighty stump]

Check the instructions in pinned messages

PPV2 is not for URP

[polar forge]

ah I see. Thank you

[quasi forge]

Sounds like it might be cheaper to just create pre-blurred assets in photoshop

[mighty stump]

Yes, usually best to fake everything you can that you don't have to accurately simulate
Also if you're working in 2D, then depth of field is really problematic as it doesn't do well with transparent geometry, which is what sprites are

[quasi forge]

Yea, good shout. Cheers

[obtuse marten]

Is there a way i can get my UI elements to be effected by my Post Processing effects in UnityRP? because i cant figure it out...

[cobalt minnow]

Because their setup is correct, or are you trying to bait an answer?

Are you looking in your scene view? Did you turn off the post processing in the dropdown at the top?

Also don't crosspost

[obtuse marten]

WDYM?

[mighty stump]

Canvas render Mode: Screen Space - Overlay is not affected by post processing
Screen Space - Camera and World Space are

[worthy lintel]

some post processing profiles?

[cobalt minnow]

So turn it on?

[brisk canopy]

hey there!
i have a camera with an output to a render texture and post processing enabled.
but the problem is that the bloom for example looks very weird on the render texture.
picture 1 is what it looks like:
picture 2 is what it should look like:

[mighty stump]

I'm guessing the render texture color format does not have the necessary depth to store HDR color, could try one like R16G16B16A16_SFLOAT

[brisk canopy]

Oh that was easier than i expected, thank you very much!

[jagged bane]

Hi I just upgraded my project to URP (2D btw) and I had an effect that used to increase the bloom and make it red on player death.

                bloomLayer.intensity.value = 2f;
                bloomLayer.color.value = Color.red;

That was the code. Now after going onto URP this code does not run, it shows no errors or anything. But on player death the bloom does not turn red and increase.

Did I maybe setup URP wrong or something?

[slender pier]

Hi anyone know how i can have a world space ui not be affected by post processing? i use urp for my post processing

[odd drift]

I dont think you can very easily. Only way that I know is to render the UI with camera that doesnt have post processing in it (camera stacking)

[slender pier]

I tried that it removes it entirely urp doest not also have the option to have post layers unless im missing somthing?

[odd drift]

No render pipeline supports that type of pp layers afaik

[odd drift]

You have to use camera stacking to merge the camera views together

[slender pier]

Ohhh ok ill try that when i get a moment

[sand sedge]

does anyone know how to make depth of field only work at a certain y level, i want to create the effect to provide distinction between diff levels in my "isometric" (its a perspective camera moved out and set with a low fov) and the current depth of field blurs most of everything in the top half of the screen

right now it is very hard to see distinction bvetween the two platforms

in deaths door its done very well

[mighty stump]

Your best option is to render them on separate cameras, with only the layer below having DoF
Afaik an ortho camera doesn't provide the depth necessary for DoF to work anyway so stacking might be the only way to do it, though I'm not sure

I think a better option than depth of field would be to use lights and shapes to communicate different levels

Seems unlikely that your background detail must have the exact same lighting, texture and color as the foreground

[sand sedge]

Yeah I’m def doing that as well but I’d like to have depth of field for times where I can’t really place objects or change lighting

[sand sedge]

Yeah I’m using perspective rn not ortho but I think the same method works

[mighty stump]

Looked like ortho, but if you use perspective with a tight fov, then you probably can do with just the basic DoF
Even if it's not per layer, the biggest depth difference will be by height effectively

[sand sedge]

Yeah idk tho the default DOF barely does what I need it to do and barely shows any real effect even on very distinct objects

[paper helm]

Is it possible to have per-object parameters for a post processing effect?
Am I misguided in thinking a post processing effect is suitable if I need per-object parameters?

[mighty stump]

Normally post processing is per-rendered image and local post processing overrides are per-camera
It's possible to combine separately rendered and post-processed images, or volume overrides that add some effect to components within them but it's up to you to implement them

[simple torrent]

hey the camera for ui overrides the post processing settings for the main camera even while the volume mask on UI layer only, any quick solution to fix that?

every other gameobject isnt even set to ui layer but still affected by the volume

[mighty stump]

Post processing in stacked cameras applies to the whole rendered image at that point in the stack, including images from cameras rendered first
Post processing volumes affect cameras, not any other type of gameobject (with specific exceptions)

[simple torrent]

bruh

i wanted to make a volume for my ui and volume for everything other

[mighty stump]

There's no system out of the box to apply post processing to just one rendered image, then compose it with other rendered images, afaik
But it's possible to code one

[subtle thistle]

Any clue on why dopes my bloom not work?

nvm, didn't check is global lol

[spark yarrow]

What are the Sonic Ether's SSAO and SSAO Pro effects? Because I found a bunch of people talking about them (https://forum.unity.com/threads/ssao-pro-vs-sonic-ether-ssao.326212/), but I can't find those effects anywhere

[mighty stump]

The thread is from 2015
My guess is that the assets mentioned are long obsolete

[spare osprey]

Can I lerp a chromatic aberration effect during runtime? Like maybe through an animation or something?

[sharp summit]

what do you mean by lerping chromatic aberration, of course you can lerp the setting that control these effects tho

[spare osprey]

I mean, say I have a character that has a dash move. I want to have the chromatic aberration go from 0 -> 0.5 to sell the speed of the dash. The only issue is that I can't seem to effect the variables in the animator panel.

And Mathf.Lerp is having issues as well.

But mainly, I would like to use the animator because then I get a tighter grip on how I want to blur to look.

Oh shit wait

nvm figured it out

lol

[fiery hare]

yea , u can

i did with dotween but pretty sure u could do it normally too

[cinder ruin]

https://youtu.be/5dzGj9k8Qy8?t=868
Sorry, in this video Brakeys applies bloom only to the sprites with shader, but in my project, if i follow his steps, i get this result

I want to add bloom only to the yellow part around the red card. Why all the elements glows?

[spare osprey]

I found a work-around, but thanks for the heads-up anyway

[mighty stump]

Threshold value, as he mentions in the video

[cinder ruin]

Oh ok ty, can i lower the field intensity?

[mighty stump]

If you want?
High bloom threshold and high emission intensity mean only those emissive materials will pass the threshold and glow

[cinder ruin]

Thank you, now I understand, I'll do it this way!

[drifting tulip]

Hey folks, I'm hoping to write an HLSL post processing shader with access to the gbuffer in 2022.2.x + URP. I see in the documentation (https://docs.unity3d.com/Packages/com.unity.render-pipelines.universal@14.0/manual/post-processing/post-processing-custom-effect-low-code.html) there are instructions on creating a Full Screen Pass Renderer Feature and passing it through a Shader Graph. Experimenting with this shows I can just give the renderer feature a material, so it seems I should be able to pass in a material with an HLSL shader attached, but I'm struggling to get this to work as expected. The docs don't seem to cover this case. Is there some example or documentation I can refer to, or is this path not possible for some reason I'm not immediately seeing?

[drifting tulip]

Well, I've been able to reverse engineer enough from a default "Fullscreen Shader Graph" exported to HLSL that it seems to be working and I can probably hack the rest together, but I'm still interested to see if there is more documentation on this, as it's slow going piecing together what's critical from all the stuff Shader Graph generates.

[fiery copper]

idk why my post processing won't work I made sure everything is how it should be from layer to whatever and it still not works I even removed it and started over but still no good

[marsh frigate]

You're using the built-in render pipeline?

[fiery copper]

lemme check

I think yes

[marsh frigate]

It looks like URP

Which means you are using the wrong components and package

[fiery copper]

fr?

[marsh frigate]

https://help.vertx.xyz/graphics/post-processing/render-pipelines

[fiery copper]

I looked at this but I did not understand much

I tried to do everything it said

[marsh frigate]

• Then why is that clearly a Post Process Volume component, from the package it tells you to remove

[fiery copper]

I did remove them

wait I think I got it

ok I got it

but

it only shows in the scene and not in the game scene

[fiery copper]

how do I enable post process on camera?

nvm found it

now it does not work again

😭😭

[cobalt minnow]

If you're using URP:

1. Remove the post processing package if you've installed it. That's for built in.

2. Add the Volume component to your scene

3. Create a post processing asset and assign it to the volume

4. Turn on the Post Processing toggle on your camera

5. Test with something easy to see, like Vignette

That's all there is to it

Bonus: make sure you have post processing enabled in your scene view too. The drop down is at the top of the scene window.

[fiery copper]

thanks

[swift urchin]

Hey
I'm not sure if it is the problem buuut
My scene looks so much brighter while playing it (darker in editor)

I think that this is because of post processing is getting of
Any ideas why does it?

(Left is with processing - view in editor, right without one - view ingame)

[blissful cedar]

using DrawRenderer custom passes with TAA cause massive ghosting artifacts, any ideas on why it would happen?

[mighty stump]

I know that TAA needs motion vectors to know where objects are going, so the smoothing can happen forthe correct pixels

[blissful cedar]

I got motion vectors enabled on everywhere

I use these to render my arms/weapons before everything else to avoid wall clipping

motion vector settings are enabled on mesh renderers

also in render pipeline asset

for god's sake

[plush pumice]

no post processing on your game camera

[swift urchin]

Thank you very much!
My bad 😅

[sonic zenith]

Hello

I'm trying to create some custom post process effect with a material created at rumtime

like this:

Shader shader = Shader.Find("CustomSRP/PostFX/Bloom");
Assert.IsNotNull(shader, "Shader not found: CustomSRP/PostFX/Bloom");
_bloomMaterial = new Material(shader);

It works, but I wonder whether I need to destroy this material by myself

or it'll get GC'ed

The material is not attached to a renderer, nor saved in the disk. It's purely created in render pipeline C# code

[mighty stump]

Pretty sure you need to
Why create new post processing effects at runtime anyhow?

[sonic zenith]

I'm dealing with an existing project and it has code like that. I know I can just create material assets in disk to avoid this, I just wonder if it's necessary

[wet coral]

What's the difference between setting post processing effects on a camera vs a Universal render pipeline asset?

And volumes

[worn pivot]

I setup a second camera that ignores post processing effects for certain objects, issue is this also ignores fog for those objects that ignore post processing. Anyway to fix this so my ignore post processing camera can also apply fog to those objects?

[severe slate]

Why doesn't motion blur work? The vignette works but motion blur nah

[mighty stump]

Hard to say exactly, and it depends on render pipeline but motion blur requires some extra things like motion vectors

[silent moth]

So, my bloom effect works on one lvl but not the rest. They all have same settings. Can someone help please?

[hazy knoll]

I'm currently trying to use Post Processing stack package in built in pipeline and i'm facing issue to apply post processing to certain objects.

I have two cameras, one which renders objects which don't need post processing and another camera which needs post processing.

Even-though I apply post process layer to affect post processing camera alone, I see always whole screen objects are getting the post processing effect. This is really annoying as i see the contents of the post processing camera is only the objects i need. But still I wonder how its applying affect on all cameras/objects.

Any help?

[severe slate]

I'm using universal
Aand what could be the reason a little more exactly

[wheat jackal]

erm.. has anybody watched the series by Ben Cloward on post processing? In the first episode he makes the base post processing shader that samples the scene's color and outputs exactly that: https://www.youtube.com/watch?v=ipKQt0BxQSA

The problem is it does not do that

this is before and after he applies the post processing filter before any effects are added in

notice the bloom is gone

and as far as i can tell, at least in like 5 episodes after, he doesn't fix it

the effect is way worse on a default unity scene, notice the sun's just flat now, as well as increased banding for some reason?

So.. PSA I guess? Maybe he fixes it later, but if you're just using his tutorial as a starting off point and doing something else after the first episode or two-- like i did-- be aware of this problem.

[hazy knoll]

Well! This turns out to be a limitation of Post processing currently where it applies the effect to the cameras stacked below it, which is terrible!!!

[supple fossil]

In scene view, when post processing is on, the gameobjects are translucent. This is not the case in game view. This is also true when there are no post processing effects and just an empty post processing layer attached to the camera. In sprite mask mode or shaded wireframe mode this is not an issue, its only a problem in shaded mode. Any help would be appreciated.

[mighty stump]

Are the objects really translucent or is the scene grid just being drawn over them?

[supple fossil]

Why would the scene grid be drawn over them?

They seem fine in game view

[mighty stump]

Not sure, but if that's the case then it's not a translucency problem that's being solved

[supple fossil]

Even if they aren't translucent it's still distracting

[mighty stump]

https://issuetracker.unity3d.com/issues/grid-gizmo-is-visible-through-the-scene-game-objects-when-the-post-processing-layer-is-used-on-the-camera this looks like the correct issue

[mighty stump]

If there's no fix out there, you can at least lower the grid opacity to make it less distracting

[supple fossil]

Thanks for the link and the suggestion

[supple fossil]

I'll just use sprite mask draw mode since it seems to be a bug in the engine

[gusty delta]

Hey there, I was wondering if their was a way to make the bloom in URP not look yellow and instead appear white.

[mighty stump]

Bloom takes its color from the color of light and surface
There is a saturation slider if you want to force it to monochrome

[gusty delta]

Found out I had set a tint in the bloom settings of the camera, now it works as intended.

[sweet drum]

How would I go getting a Vignette over a void?

I'm developing for AR, but when loading a Vignette with no skybox nothing shows up.

[somber galleon]

Hello i need help if anyone can, im having this issue with post processing where whenever i turn the intensity in bloom everything glows up im trying to make a neon affect but its glowing up the entire room, can anyone help?

[somber galleon]

nvm the issue is resolved

[ivory spoke]

hey not entirely sure where this question belong, but how hard would it be to selectivley apply a pixelation shader to things in my scene?
Is it as simple as two cameras, one capturing only the things I want pixelated, another capturing everything but that... apply shader, and somehow mix the results back together for the output?

[ivory spoke]

spoiler alert: I achieved it. it was not that simple.

appearantly camera stacking used to be a thing that made this easy, but the feature was removed due to it causing more headache and bugs than it was worth, iirc

[ivory spoke]

nevermind did not entirely figuring it out, only sort of....

I made it work for fire and particles in my game, which is great

but I also need to apply it to my water shader... which has its own transparency and this is causing issues

also the selectively pixelated stuff renders on top of everything else sans UI

[mighty stump]

Is this what you want or not? It's difficult to give any opinions when such pixelation can be done on so many different levels which all result in different interactions with other rendered stuff

[ivory spoke]

no, it is not what I want

https://i.imgur.com/JsX9gee.gif

as you can see here, the water and fire are being pixelated as I want, but the rock that is supposed to be in the foreground, over the water.... is under the water

one solution to this is to put foreground things on a third layer and make a 3rd render pass....

but thats gross, and will probably have significant performance implications at some point

or what I could do... is get the foreground into its own render texture, and use that to mask the pixelated later in the shader... hmm

still requires a third camera, but not a 3rd render pass

[pure plaza]

Hey all, I'm trying to use the post processing package to add a bloom effect to an asset I am assetbundling into a game
The bloom effect runs just fine in the editor/preview.
However, the scene in the actual game already has a camera so I'm trying to add the Post-process Layer component to it during runtime
I do that with

var a = GameCameras.instance.mainCamera.gameObject.AddComponent<PostProcessLayer>();
a.volumeLayer = 31;

Unfortunately, this results in the following error getting spammed over and over. The game still renders just fine, including the assetbundled asset, however the bloom fx does not appear.

[normal oak]

Anyone know how to make bloom affect only selected layers/cameras and not all of them? FYI I have 3 cameras, one for the main game, one for the UI and one for the shop. All except the main camera are on overlay, and all of them have their own volume profiles with blooms in them. But the cameras that are on overlay, their volume profiles/bloom also affects the cameras below. How should I go about adding them effects seperately? Also sorry for the bad explanation, I can provide some images if anyone wants to bother helping me

Nvm don't need help anymore, got it kinda working..

[normal oak]

But it still would be nice to know if it's possible to put effects only on specific cameras/layers because the blooms effects add up more and more the more bloom effects you stack

[mighty stump]

I've never seen an "official" way to do it
I assume you'd render to a separate render texture and then composit them in a custom post processing pass

[odd drift]

By using layers on the cameras you can make the effects only affect certain cameras, filtering objects by layer is not possible

[normal oak]

Yeah, used that to perform the fix

[mighty stump]

What'd you go with exactly? I assumed you used a screen space overlay canvas which is rendered after post processing

[normal oak]

I used the "Screen Space: Camera" option and then added the required event cameras to them, after that I used the layer thingy which Aleksi described b4

Then added the 2 other cameras to the main camera's camera stack

With correct ordering of course

[charred marsh]

Does post processing using a Global Volume incur a cost on mobile platforms like Quest 2? I'm referring to pixel independent effects like tonemap / vignette? As far as I can tell, it costs the same as post processing off minus the additional instructions / texture fetches

[wooden orbit]

hello

i have a problem

the post processing didn t work for me

so is there something wrong

[cobalt minnow]

If it's not working, one would assume so yes.

It looks like you're using URP but are using the PPv2 package. These are not compatible. You need to remove the post processing package you installed in the package manager, and then use the built in URP Volume component instead.

[wooden orbit]

ok

[winged burrow]

How can i have 2 post processing cameras, that each have different effects?

[jagged prism]

Why cant I juse enabel?

[mighty stump]

What does the error say and what post processing system is this

[jagged prism]

Im jusing hdrp

The error says ther is no definitoin for enabled

[mighty stump]

https://docs.unity3d.com/Packages/com.unity.render-pipelines.high-definition@12.1/api/UnityEngine.Rendering.HighDefinition.LensDistortion.html
Perhaps IsActive() is the one you need

[jagged prism]

But I want to set it to false

😕 ?

[mighty stump]

I'm trying to figure it out
This is a team effort isn't it

[jagged prism]

not really

[gritty folio]

I think it's .active = false? https://docs.unity3d.com/Packages/com.unity.render-pipelines.core@12.1/api/UnityEngine.Rendering.VolumeComponent.html#UnityEngine_Rendering_VolumeComponent_active

[jagged prism]

I tryed that but then this happense

[gritty folio]

If you're using TryGet<Tonemapping>() that might return return null if there is no Tonemapping section added to the volume

Or LensDistortion I guess, that's what you're using in the code above despite the function name

Or perhaps it's the fx or fx.profile that's null? Try some Debug.Log stuff to check

[jagged prism]

ok thanks

[mighty stump]

I thought this is for the volume itself, not the override

[mighty stump]

That makes you sound incredibly entitled
I'm going to assume you didn't mean it that way

[jagged prism]

no

[gritty folio]

Yeah bit confusing but I think it should be for the override since VolumeComponent is the the base class for those. While Volume would be the class for the actual GameObject component. (some great type naming here 😔 )

[mighty stump]

https://docs.unity3d.com/Packages/com.unity.render-pipelines.high-definition@12.1/manual/Volumes-API.html
The first example here also uses ".enabled.value"

But I can't tell if that's for the whole profile or an override

[gritty folio]

I think that's because the Fog override in particular has a Enable checkbox

Yeah looks like it https://docs.unity3d.com/Packages/com.unity.render-pipelines.high-definition@12.1/api/UnityEngine.Rendering.HighDefinition.Fog.html#UnityEngine_Rendering_HighDefinition_Fog_enabled

[mighty stump]

This works perfectly

[random terrace]

hi, does SSR(Screen Space Reflection) post processing already supported on VR?

[lethal drum]

Hey guys, does anyone know how to add a post processing volume to a camera that is projecting to a render texture? Or do I need to make my own shader in shadergraph/write a custom shader?

[mighty stump]

This is the post processing channel

[mighty stump]

I'm not very familiar with VR, but I think all effects are supported as long as your VR device's graphics API supports the required features, and has the performance for it

https://docs.unity3d.com/Manual/GraphicsAPIs.html
More info about specific graphics APIs and platform-specific rendering differences from here

SSR in the Post Processing Stack requires

    Compute shader
    Motion vectors
    Deferred rendering path
    Shader Model 5.0

A lot of platforms might not support all of those
HDRP has different requirements but you're probably not using it for VR

[mighty stump]

I think you can specify post processing per-camera using layers and layer masking, just how you would for a non-RT camera

[random terrace]

thanks for the information 👍

[lethal drum]

I actually managed to get a vignette effect working which was basically what I needed to be honest but thanks

I'll probably need to come back to it later

[visual pebble]

            if (desaturateData.IsActive()) {
                material.SetFloat(Intensity, (float) desaturateData.intensity);
                
                Blit(commandBuffer, src, desaturate, material, 0);
                Blit(commandBuffer, desaturate, src);
            }

How do I use a stencil test when writing from one texture to another in a renderfeature? I want to only apply this post processing effect to parts of the screen selected with stencil. (I am already writing to it)

[golden smelt]

How can I download unity post processing stack?

[gritty folio]

Assuming Built-in RP, you'd install the "Post Processing" package via the Package Manager window. There's docs links in pinned messages for more info

[gritty folio]

I think it's not possible with a blit. But you can swap it out for drawing a fullscreen quad instead.
The important thing would be using cmd.SetRenderTarget with both a colour target (destination tex) and depth target since that's where the stencil bits are stored.
To make sure the quad is fullscreen, You'd also need to make sure the vertex shader is just outputting positions in clip space rather than doing transformations, OR temporarily set the view/projection matrix to Matrix4x4.identity.

This might help with all of that, though is a bit outdated now (RenderTargetIdentifier is deprecated in favour of RTHandle in 2022+) : https://github.com/Cyanilux/URP_BlitRenderFeature/blob/cmd-drawMesh/Blit.cs

An alternative to using stencils would be passing your own mask texture into the shader used for the blit.

[formal mantle]

Hi All! Does anyone know how to do this flash bomb that’s appear on screen and fade out? https://youtu.be/naXFartSYhs you’ll find it on the 4:39 minutes

[severe slate]

Hey

How do I make the sky not have bloom ;-;

cuz is kinda annoying

[mighty stump]

Increase bloom threshold

Make sure you're using linear color space so bloom threshold can function properly

[stiff karma]

Can someone help me? I added post processing to my game, but it doesn't work on my UI.

[mighty stump]

Set your Canvas to screen space - camera and Render Camera to the one with the PP

[wintry knot]

I have a post processing layer attached to my main camera and a pp.Volume with motion blur activated attached to my Player. The camera is also attached to the player. The game still looks the same and motion blur doesn't work.

[mighty stump]

Motion blur can be trickier to get to work than other overrides
I recommend to try with vignette first to confirm that the post processing is working

[wintry knot]

everything except motion blur is working

[mighty stump]

Motion blur problems are often related to motion vectors or their settings

[wintry knot]

what would be a common problem with motion vectors as an example?

[wintry knot]

it works, idk why, but it does. Thanks for your advice

[pale ruin]

I tried to add glow effect to a certain gameobject with post processsing but it doesnt work unless I activate isGlobal on the post processing volume anyone know why?here is my PostProcessingVolume and PostProcessingLayer settings

and yes I have set thee layer in post processing layer and the game object to match eachother

[alpine tangle]

if you dont tick isglobal it puts the post processing local to the position of the volume, using the collider, blending it in based on the blend distance

[pale ruin]

So I need to modify the value here?

[alpine tangle]

or make the collider bigger

[pale ruin]

tried to make the collider bigger and changing the blend distance value to either positive or negative and none of the works

[alpine tangle]

oh its 2d? never tried that, might not work with local volumes

the camera needs to be inside of the collider trigger

[pale ruin]

oh ok btw thanks for the help really appreciate it

[keen tapir]

can I somehow get rid of the flicker on bloom when a small object is moving? using Pixel Perfect Camera with upscale render texture and bloom from the Volume component
seems to be tied to resolution in some way
https://streamable.com/mo86mc
I found a bug tracker report but it was marked as "by design" (https://issuetracker.unity3d.com/issues/2d-urp-global-volume-bloom-post-processing-flickers-when-object-moves-in-the-view-space) but I'm making a pixel game its expected for things to be relatively small, sometimes 1 pixel, but it happens even if the object is as large as 5 or more, just a bit less intense, so is there a way to work around this?

[severe slate]

Hey. So\ im pretty new to lightning and stuff but I added post processing and I was trying to make nighttime and this happened (I rotated my directional light)

[mighty stump]

Don't crosspost
"This happened" tells absolutely nothing to us

[severe slate]

Basically I rotated the directional light and added pp and put that yellow glowing cube there for testing. Whenever I baked it, it looks like that.

[mighty stump]

"like that" as opposed to what?

[severe slate]

i fixed it. is alright

[mighty stump]

What turned out to be the problem

[severe slate]

me being too dumb

to put down a light source

[wary swallow]

is there anyway i can disable post processing?, as none of my objects use it and it is taking up 70% of my performance

[mighty stump]

In URP you can disable it per camera, and with effects like SSAO they can be disabled from the Renderer Asset
In BiRP you can disable the post processing layer component
In HDRP post processing is heavily tied to the whole render pipeline, so you would disable individual volume overrides, or disable rendering features from the Frame Settings entirely

[wary swallow]

thanks a ton!

[mighty stump]

Though in most cases post processing is not supposed to be that expensive, I'd try to figure out if a specific effect is the culprit before disabling all of it

SSAO especially in URP tends to be more expensive than all post processing and even rendering combined

But it does depend on your render pipeline

[wary swallow]

I'm not even using any as far as I'm aware lol. My game is a simple 2d pixel art randomly generated type game in urp if that helps. Disabling it shouldn't matter much though. thanks a ton!

[thin prairie]

how can i make a variable for the color format of the TextureRenderDescriptor ?

i cant find anything about that anywhere

but I saw a video where someone made a custom settings class and took the colorFormat from said class so it should be possible somehow

[thin prairie]

i figured that out but i have a new problem

i always get this error, that i honestly dont realy understand but at line 34 theres nothing wrong i simply assign a material to a material variable and the material is assigned in the editor

[thin prairie]

Okay i fixed that too
