Hi, did 2D Experimental Pipeline works in 2020 version of Unity?

[turbid matrix]

you mean URP's 2D? I think it's been there at least since 2019.3, could have been before that

[solar knot]

It works?

If i switch?

[turbid matrix]

can you be more specific what you mean by that?

[solar knot]

i have last 2019 version

if i switch to 2020 version

[turbid matrix]

https://docs.unity3d.com/Packages/com.unity.render-pipelines.universal@10.3/manual/2d-index.html

but 2019.4 can use it as well https://docs.unity3d.com/Packages/com.unity.render-pipelines.universal@7.5/manual/2d-index.html

unless you mean something else now

[solar knot]

Im switching from 2019 to 2020, and i'm interested, how much errors i would have with my project

that uses 2d urp

[turbid matrix]

just test it

[solar knot]

I have crashes in 2019 version of unity

[turbid matrix]

I mean you probably have version control and backups... so try it?

[solar knot]

Sure

thx

[turbid matrix]

I can also tell that the same artifact that was present in old SSR mode is still preserved in "raymarching" mode when using "reflect sky" option that didn't fix itself at least 😄

is this a known issue?

I mean I've seen it gotten mentioned few times by users, including myself when the accumulation denoiser appeared but I dunno if there's like issue report made for it

(it does appear on approximation as well apparently, I could have sworn I didn't see it on that mode before but I could remember wrong)

sky reflection has always been sketchy on HDRP SSR though

[indigo summit]

So i'm wondering , about the SSR situation. There's a lot of SSR implementation already that work mostly fine of course with the limitation of screen space artifact limit, why not implement those first then working on a new implementation? this way at least HDRP have an option to choose working SSR while waiting for an improved version?

it's just from the beginning of HDRP it seems we never have a working version of SSR, always have issue which we never see in other SSR implementation.

[turbid matrix]

@heavy ice hmmm, I don't actually get vertex modifications to do anything for the hybrid reflections, it just shows the static raytraced reflection despite the mesh it reflects is moving via shader

I have dynamic geometry set on the mesh moved by shader but it didn't change anything

there's also some flickering going on in the editor but I dunno if it's from this change

[heavy ice]

Ray Marching option the dropdown is not new

Ray Marching is just the new way to access SSR

the Ray marching technique in Hybrid is new, but it is not ssr

not sure if it is clear

[turbid matrix]

yeah, I saw the same options as on SSR

but for the vertex offset in shader... is that supposed to work in reflections when using hybrid?

[waxen lantern]

as i understand more than one technique is available as an option? not just this new "hybrid" tracing option @turbid matrix is testing. and there's definitely room for improvement but the ethos of SSR is and always has been about making compromises and accepting some limitations and artifacts one way or another.

[waxen lantern]

other render pipelines and engines have SSR issues too you just rarely see them because it's not used for mirror reflections or in a discerning testing environment like this.

if you really need perfect mirror reflections, you should use "worldspace" raytraced reflections.

which, to your point could mean HDRP devs are less concerned with the accuracy of SSR than ever before, since it's considered a "fallback" method to RTR / ray traced reflections.

though this hybrid ray marching method being developed says otherwise. it's just not very far along

[waxen lantern]

i personally will bet on no it's not meant to work yet, as vertex offset doesn't work for hardware accelerated RTR / DXR reflections yet either. and this hybrid raymarching method seems like a further attempt at making a software raytracing reflections fallback for hardware accelerated raytracing reflections. (to be used instead of screenspace reflections.)

[turbid matrix]

yeah but, wasn't the whole point of this to get things showing on the reflections that are not supported by current raytracing setup?

also the PR did list vertex animation as supported

[waxen lantern]

oohh

[turbid matrix]

or rather suggested to test it

I'm just wondering if I'm missing something here 🙂

[waxen lantern]

i didn't see it that way. i meant a total fallback for platforms without raytracing hardware,... but i can understand a mixed approach being desirable at the current time

[plain mural]

in hdrp, if you use dynamic resolution and screen space ui, unity scales the ui based off the cameras resolution, how the hell can i fix this?

im rendering to ui on a custom pass after post process

[turbid matrix]

there's been some fixes to dynamic resolution recently but I dunno how much of it applies to your use case (or if the fixes have landed on version we can use today)

sounds silly if they really force the whole resolution like that

you'd always want to render the UI at native resolution if possible

[plain mural]

exactly

maybe if i set the resolution back to full before the ui pass? im gonna try that

how do i add code right before a custom pass?

[turbid matrix]

I'm confused, don't you literally get some code snippet when you generate the custom pass thing?

[plain mural]

im not sure

[turbid matrix]

https://github.com/Unity-Technologies/Graphics/pull/3428

[plain mural]

is there a method that executes right before post processing?

or right after it, rather

[turbid matrix]

"Fixing resolution problems with CAS. CAS now renders exactly the resolution of the viewport."

[plain mural]

thats not what i was looking for

[turbid matrix]

yeah I dunno what that even means 😄

but for the custom pass, have you done these before?

docs tell the basics https://docs.unity3d.com/Packages/com.unity.render-pipelines.high-definition@10.3/manual/Custom-Pass.html

they list the places where you can inject custom passes and also custom post process effects

there's place for After PP

[plain mural]

yea i have the custom pass injected after post process, which is what i want

i just need to execute some code right before my custom pass

[turbid matrix]

you can use your own code for the custom pass

there should literally be option to generate a template for you in the right click menu

but I'm not really sure what you are looking for here

https://docs.unity3d.com/Packages/com.unity.render-pipelines.high-definition@10.3/manual/Custom-Pass.html#scripting-example-outline-pass

[plain mural]

this might be what im looking for

my editor froze for some reason and i have to restart

thanks for the link

[turbid matrix]

@plain mural https://github.com/alelievr/HDRP-Custom-Passes probably have few effects that run on custom scripts too

(in case one wants to see how these can be used in practice, docs don't really explain everything in depth)

[plain mural]

ok so how do they get the custom pass script to interact with the custom pass component?

im confused on how it all works together

im using a drawrenderers custom pass

[plain mural]

still cant figure out how to get camera space ui to render at full resolution when using dynamic resolution scaling

[indigo summit]

Hmm of course i'm not expecting perfect mirror reflection with SSR, mostly issue that i've found with the implemented SSR in HDRP like it's not reflecting the sky properly or having blocky artifact at the edge reflection (not the edge of the screen mind you).
But if the hybrid are working just fine then i'm fine with it.

also i'm not planning to target RTX or using any raytracing (at least for now)

[pale kelp]

Hey so anyone know the solution to an imported terrain map being spiky? like the baking bar finished but it's still really spiky

Never mind. I just switched the byte order to windows instead of mac and it was fine

[heavy ice]

@turbid matrix the case you are demonstrating cannot be solved by ray marching. the bottom of the cylinder doesn't exist in screen space. here is a working example

[viscid solstice]

@turbid matrix Do you know anything about frame settings?

[turbid matrix]

@heavy ice yeah but it didnt even reflect the part change that was in screenspace..

Or rather it's change

Anyway I try another direction just to be sure

[heavy ice]

Yeah but it doesn't work that way, it is not because you see something that it is guaranteed to be seen by ray marching

[turbid matrix]

@heavy ice it's not that, it just doesn't do anything different from raytracing option for me, suggesting there's something off

I changed my shadergraph to move sideways and it's same, it's only showing static raytraced reflection while object moves sideways via vertex position offset

[heavy ice]

then maybe there is still some UI issues. go back to ray tracing, force it to performance and go back to hybrid, see if it helps

[turbid matrix]

I tried that yesterday and now again, nothing 🙂

does this feat require SSGI to be enabled on frame settings? I only toggled reflections on

oh wait, I mean in HDRP asset, apparently SSGI is now checked in frame settings out of the box, just not in hdrp asset

well, toggling SSGI enabled also didn't change anything for me

I'm testing this on 2021.2.0a6.1011 if that matters

there's no errors on console

is there some specific setup there needs to be on the shader / mesh renderer for this to work? since it relies on ray marching, I'd expect it to work regardless of the raytracing settings there (but I did test different ones there too)

@heavy ice I can zip the project and send you a link if you want to take a look

but essentially, all I did:

• made new 3D project with 2021.2.0a6
• referenced your HDRP branch packages to it
• ran HDRP Wizard for HDRP + RT
• enabled reflections from HDRP Asset
• added reflections to DXR volume
• added those few primitive + SG I linked here earlier

I did now try wiping the library folder just to make sure there's no funky things on cache but it didn't change anything

(I also waited it to bake all shaders on the background task)

@heavy ice well... I got something different now 😄

I mean not related to that library wipe.. but I played with settings

if I put quality on hybrid mode to custom, it actually shows the raymarched reflection WITH the raytraced one

any other quality level and it just shows the raytraced reflection

[heavy ice]

ok that looks more like it

[heavy ice]

Yup, it is what you should expect with such a deformation

now it is wierd that you don't have it in low

or medium or high

[turbid matrix]

even with custom, I get the raymarched reflection regardless of the ray max iterations RT value

I get how this works now

so basically if I wanted to only have raymarched reflections for some objects but RT reflections for others, I'd just mark the objects I don't want in RT reflections to have RT mode off in mesh renderer and it would do what I expect

[heavy ice]

yes

[turbid matrix]

that's great, can deal with this for now for getting some reflections on particles and foliage 🙂

works fine now

(besides the quality setting)

[heavy ice]

please mark the quality setting repro on the PR i'll look into it

when I am back on it

[turbid matrix]

also the docs change seemed to have one outdated image and wrong texts still but I assume that's still WIP?

(there's no raytracing toggle anymore)

[turbid matrix]

just did 🙂

[turbid matrix]

@heavy ice I get it is not in this implementation but is there possibility on doing like raymarched part for things that have screenspace data and then fallback to raytracing for pixels that miss rays on the screenspace buffer? I'm mainly thinking foliage now where it would be nice to get vertex animation from screenspace data and on the parts that get occluded would fall back to nonanimated raytraced data

I dont know if it really would work nicely enough to warrant the extra work

But now we fall back to reflection probes for that and its way more off

[turbid matrix]

I saw the quality setting fix. Not on work computer right now so will test later :)

[turbid matrix]

@heavy ice I did retest it but it still doesn't work on my end on anything but custom. I tried wiping the library cache and redoing the SSR override in volume

[heavy ice]

close/open unity

[turbid matrix]

I did after library wipe

I also noticed you added some global values on the fix, do they apply to the volume override even?

[heavy ice]

close unity, delete libarry and try again

i tried it myself

[turbid matrix]

I just did 🙂

[heavy ice]

in this order

or in the other order

[turbid matrix]

I always delete the library when Unity editor is closed 🙂

but I can do it again 😄

[heavy ice]

Really weird

[turbid matrix]

there could be some leftover in the volume I suppose

yeah it'd definitely not working on my end

[heavy ice]

you are sure you grabbed that last commit?

[turbid matrix]

I tried even redoing the whole volume from scratch

yes

triple checked that too

@heavy ice I feel like there's just setting missing from the component override itself... for example when I set quality to Low, Medium, High, I still see the Ray Max Iteration RT override. Shouldn't it be disabled and handled by the preset?

setting that value with those quality presets doesn't do anything though but if I set that value to 0 on custom, I don't get any reflection

so if same thing happens on the quality presets, it would explain this

@heavy ice

it will always return 0 regardless of the quality setting

[heavy ice]

it is serialized in your project

it is missing in the asset for you to change it back. The issue is you grabbed the branch in an intermediate state

[turbid matrix]

btw, should that RTRRaySteps be copied here as well? https://github.com/Unity-Technologies/Graphics/blob/HDRP/Add-Hybrid-RT/com.unity.render-pipelines.high-definition/Editor/Lighting/Reflection/HDScreenSpaceReflectionEditor.cs#L290

[heavy ice]

That is not the problem, anyway i'll ping you when the fix will be pushed

[turbid matrix]

I don't see RTRRaySteps in serialized lighting quality settings either

@heavy ice redoing HDRP Asset did fix it

also tested doing the HDRP asset again before this PR's changes and then upgrading the branch

it still seems to work so it can generate the needed values now

I still feel that the Ray Max Iterations RT should be disabled when the quality setting overrides it as it can only confuse users

[solar knot]

After i switched from 2019 to 2020, my 2d URP started to flicker

what can i do?

All point lights are flickering

[jolly knoll]

guy how i can define this .....

because he is triggering me

[worldly cape]

I was trying to test out the HDRP x DXR with Unity 2019.4.16f1 and even version 2020, but I kept getting this black flickering whenever i moved the mouse. I tried doing "fix all", searched the Unity forums, couldn't find an answer. I've never had it in URP though @solar knot

& I should mention, my issue wasn't even lights. I created a new scene and deleted everything - screen was still flickering black when moving the mouse. Couldn't figure it out.

[solar knot]

I switched again to 2019....

[solar knot]

You was using 3d? right

[worldly cape]

Yeah 3d

[solar knot]

in 2019 version?

[worldly cape]

Yup and tried 2020 too.

But again, this was HDRP x DXR, not URP.

URP works fine for me.

[solar knot]

Oh, URP 2d experimental flickering in 2020

[worldly cape]

Yeah, i'm wondering if it was what was happening to me in hdrp x dxr. Black flicker of whole screen every few seconds while moving the mouse.

I searched all over Unity forums, couldn't find the answer.

[solar knot]

Same as me, when camera moves

The most important rule is not switch versions of unity

if you are making a game

I lost 1 day of work because i noticed too late

[hot furnace]

Hello everyone squirell bat her, hey i upgraded my urp project and now everything is pink uhhg i upgraded to urp materials they already were and im using urp pipline

Im upgrading in the package manager 🐸

No luck : (

[dawn sorrel]

Hey everyone, all of a sudden randomly HDRP volume lighting simply just stopped working, no matter what fog attenuation distance is set too the fog is simply just not there anymore (even tried a new scene).

Any tips on how to fix this?

[dawn sorrel]

If it means anything it all started when I dropped the HDRPHighQuality to be the one being used. Even if I go back to the one I was using before it still isn't working 😦

[dawn sorrel]

Found a solution - I had to increase base height

[dawn sorrel]

Now another problem. The sun spikes to extreme intensity when turning towards it. (It's not exposure), i've adjusted all the settings to minimize it to the max and doesn't help.

[mortal forge]

Looks like the culprit could be some overly aggressive default HDRP bloom or similar

[dawn sorrel]

Yeah i was thinking that might be an option to check too. I checked it again just to be sure - it still does it (granted not as hard), but it just sharply pops up like it does there, maybe 5-10% not as intense.

Actually I just turned off the entire volume and it still does it 😦

I'm fine with it getting brighter, it's just how quickly it happens. That's disorienting lol

Just decided to import Enviro Sky, it works as I'd expect lol

[mortal forge]

Objectively that effect is bloom so no idea what else could be causing it. Either that or flare

[dawn sorrel]

is Tonemapping even needing in HDRP? I've noticed ACES and no Tonemapping look identical.

(In response to what you just put) - Yeah I've checked all of that and unfortunately still happened.
It wasn't doing this earlier, it randomly just started happening - I haven't even touched the directional light to be honest until all this happened.

[mortal forge]

I didn't think HDRP let you do "no tonemapping" - pretttty sure they always force something even if you untick it

[opaque temple]

Hey everyone. I have a huge problem. Im currently creating a game project which is using URP and Unity Terrain Tool. After creating 4 texture layers in "Texture Paint" tool every next texture which im adding to layer palette is totally dark (bugged). I read that URP has limit to 4 layers but also there is some way to get around it. But i don't know how 😦 I spent few hours trying to fix it but i couldn't. How can i do it? Making whole game with 4 textures would be... difficult....

[edgy tree]

Hi, how do the performance | batches | calls of projector in HDRP scale with the number of objects | area covered? Has anyone tested it?

[whole fossil]

do you mean the decal projector component?

if that, the documentation states like this:
You can use thousands of decals in your Scene simultaneously because HDRP instances them. This means that the rendering process is not resource intensive as long as the decals use the same Material.

[edgy tree]

Yes, the decal projector.
I was thinking about using a single but a lot bigger one but I guess I could use multiple to make some sort of chunk system around the whole terrain.
I have two big Render Textures that have wind, burnt floor,.... data written in them on runtime. So I had an idea of using one for the whole map but I'm not sure how the performance will go.
Guess I'll have to try it out. 🙂

[rich spade]

on a whim I've been using a decal for whole of my map (projected grid) for a while now and it performs far better than other options, however this in URP but I'd imagine same for HDRP.

[viscid solstice]

Hey, does anyone know how to enable/disable frame settings in HDRP, in regards to the HDCameraData?

[red veldt]

does anyone know how to fix this almost fog looking effect in HDRP i have no clue waht or how to fix it, also when ever i go near objects the scens lighting goes super big and its super bright

[dawn sorrel]

@red veldt add an exposure to a volume component. I generally always set it to automatic histogram.

[red veldt]

so like add a volume on a game object and add exposure?

[dawn sorrel]

Perhaps someone can help me with my new issue. I updated to 2020.2.7 and now any camera I add to scene is blurry acting as if it's things are offset multiple times (HDRP)

[dawn sorrel]

Yeap. Create a new gameobject, add Volume component to it, then add Exposure to it

[red veldt]

alr

[dawn sorrel]

If that don't do it, add Indirect Lighting to the volume and change the diffuse value to like 0 and see what happens

[red veldt]

how do i make it to auto histogram or is that just auto

[dawn sorrel]

Tick on Mode checkbox and change it to automatic histogram

[dawn sorrel]

Interesting. What version of Unity are you on?

[red veldt]

2019.3.1

HDRP is at 7.2.1

[dawn sorrel]

Ahh that might explain it, automatic histogram is relatively new.
However you can try messing with fixed, etc and see if you can get it where you want

HDRP is now in the 10+ version area, so a lot of new things

[red veldt]

wait would i have to import extra post proccessing data

[dawn sorrel]

No, don't do that, it isn't compatible with HDRP

Volume is made specifically for HDRP/URP

Ohhh that, idk - perhaps

Sorry I thought you were talking about the Post Processing Effects that is separate from HDRP one lol

Yeah you can try and see what happens

[red veldt]

yeah, i did still no auto histogram option

[dawn sorrel]

The options you have now should at least make things not as bright. Just try messing with the values. Auto Histogram won't solve it either - I just prefer it as it is great for going outside from inside and such.

But Fixed, etc should work for what you want. But HDRP 7 is dated now, so you probably won't find much support in that area as most people using HDRP from what I've gathered are using the newer ones because it's just much more stable for the most part.

[red veldt]

yeah i would update but the new unity updates are large for me so i stay down

[dawn sorrel]

I'm not sure if it's still available, but Unity does have torrent downloads (officially), not third party theft kinds lol

So you can download and stop when you feel necessary

[red veldt]

ill take a look into that

[dawn sorrel]

Yeah 🙂

Just keep in mind - always backup project before making any engine updates.

[red veldt]

yep

[dawn sorrel]

I generally don't LOL. I risk life and blood on updates all the time LOL

[red veldt]

i used to do that to but i got unlucky one time

[dawn sorrel]

Im so impatient that I'd rather re-build things than wait 2+ hours on backing up haha.
Yeah heheehh

[red veldt]

yep

[trail dew]

Hey guys, is it possible to turn zwrite on for shader graph shaders?

Or do I need to compile them and use the compiled shaders?

[hollow orbit]

post in #archived-shaders

[trail dew]

I made a related post earlier but nobody seemed to know

I think I just need to put this problem aside for now

[dawn sorrel]

This camera issue is really strange. It only happens on a scene that existed after the update.
I've tried disabling volume components, etc.

Another gif of it, rotating the X axis of the camera

[dawn sorrel]

I found the cause - It was Enviro Sky HDRP. Apparently ticking SetActive false didn't disable the issues, I had to actually delete the envirosky assets from the scene and now it all works

[reef narwhal]

can someone pls help the shadows are pixelated and the characters is a little pixelated Im using URP

[rich spade]

you will need to tweak the Universal Render Pipeline Asset, look in the shadow settings. for me a normal bias of zero works, but you may have to experiment a little

[reef narwhal]

ok thanks

[torn tree]

Hello there,

I am having an issue with the universal render pipeline.

When ever i place a light nothing changes and the scene is always lit no matter what.

I added the pipeline to an already existing project,
Added the pipeline to the project settings -> Scriptable pipline settings
Added the 2D Renderer Data asset to the Universal render pipline assets Render list
Upgraded the Project Materials to the URP Materials

Is there anything obvious I am missing that might be causing this ?

[jolly knoll]

No body have solution or documentation ? ... crazy

[sweet mica]

https://gifmaker.me/files/download/home/20210306/03/NL6GbSdDVO6COOSJaInoSH/output_EIs8yv.gif

why this is happening when i zoom in

[rich spade]

is this in URP?

[bold canyon]

Trying to get stencil-based portals going, but am having trouble with cutting out things with the stencil buffer:

[sweet mica]

yes

[bold canyon]

I have the following setup:

1. URP Renderer
2. Render is set to not render opaques by default
3. First Render Feature is a pass that doesn't render anything but is supposed to write the depth buffer
4. Second Render Feature is a pass that renders the portal cutout geometry and sets the stencil buffer
5. Third Render Feature is a pass that renders opaques but if the stencil buffer is set, doesn't render it

For some reason, the "depth test" render pass doesn't work

[rich spade]

it looks like shadow cascades to me, look at the settings in the URP render asset under the shadow setting try tweaking them. I find a lower normal bias is needed.

[bold canyon]

despite the fact that the depth test of the "portal cutter" feature is supposed to fail in this situation, it jsut.... doesn't

so, either "Write Depth" doesn't work or "Z Fail" doesn't work

Does Unity not follow the order the render features are in?

because that's about the only explanation that makes sense here

[sweet mica]

@rich spade thanks but nothing happend even if i make cascade 100 or 0 , even cast shadow or not cast options didn't effect to that thing

[rich spade]

if switching shadows off didn't switch off shadows in the scene then it's probably the wrong asset your editing (assuming you have more than one). But if none of that affects the problem then I've no idea better idea's I'm afraid.
Perhaps someone with more experience / has overcome similar problem will chime in

[sweet mica]

oh thanks for your answers i found it . on terrain setting , i increase base map distance and fixed it

[bold canyon]

Two questions:

1. Does Unity clear the stencil buffer between frames in URP?
2. Does Unity clear the stencil buffer between rendering different cameras in the camera stack?

[spare marten]

Hi! My materials are gray after upgrading to hdrp, please help!

[hot furnace]

Any news about realtime point light shadows in urp, can i get those? Especially for 2019lts 🌀🌊🏝🌊i know its expensive six shadow maps but my spells and forest wisps need it 🐞

[turbid matrix]

@spare marten issue with light intensity and exposure values

basically if you've ran the HDRP Wizard through (you really should if you haven't), when you create a new scene you should get HDRP safe defaults

you can duplicate those volumes and lights on your own levels

[turbid matrix]

you need 2021.1 beta or newer to get those

I doubt unity will backport those

[hot furnace]

@turbid matrix nice thanks , in your opinion how is 2021.1 beta is it ready enough for government work

[turbid matrix]

considering it's tech stream and beta, I'd go with... no

would stick with LTS unless you just want to experiment

[hot furnace]

@turbid matrix thanks man

[hot furnace]

@turbid matrix cant resist ssao and point light shadows, i have to experiment i saved a backup im gunna see what its got thank you so much i didnt see the beta versions down there or know about when point lights shadows were implemented

I will be testing ambient occlusion render feature motion blur bloom and point light shadows in this bad boy a multiplayer action rpg with top side 3.4 and free view

Thank you unity, freaking bomb

It 2player local co op remember really getting together, those were the dayz

[deft marten]

Not sure if it's render or materials or whatever.. so will post it here also:
Guys,
Can you please help to understand the changes between 2020.1.1f1 version and latest 2020.2f7 ?
I just upgraded my project and colors changed.. please advise where to dig to revert the changes using newest version?
Please look on these screenshots before (dark) and after (a lot of blue).

[long wagon]

@deft marten Don't cross-post, keep to one channel.

[deft marten]

please advise which channel is related to this question? not sure if it's Renderer or shaders or ... @long wagon

[long wagon]

@deft marten It's more relevant to lighting. Not that important to pinpoint the exact channel. More annoying to get into a split discussion. So keep only one.

[deft marten]

Sure. What if Render/Shaders guys will tell me (not related to this channel)? should I delete & paste in Lighting ?

[true zealot]

You haven't even mentioned which render pipeline you're using, or what your shaders are, so both posts are lacking information relevant to the channels

[long wagon]

@deft marten Keep this one since you already in conversation here.
If you see different color I would start checking the lighting settings first.

[deft marten]

Question is more about the Unity changes 2020.1 -> 2020.2f7.
What has changed (rendered? lighting? shaders?) that affected my project this way

[true zealot]

This channel is about URP/HDRP

are you using either of them?

[deft marten]

I'm using URP

and got some message after upgrade "Since you use outdated URP.. we upgraded materials/renderer" or something

Unity message

[true zealot]

my guess would be the same as Fogsight's, that your lighting settings have changed

could be that a different scene is active

[long wagon]

Also did URP enforce Linear color space previously? It could be a switch to Linear that did that.

[deft marten]

the thing that I'm disabling/enabling everything I have in a project and it doesn't affect this.
Have only one scene

let me check

Also I noticed that, once I start Unity.. it looks as expected but once Unity app window become active.. the colors change. Hard to explain what I mean

[long wagon]

Also if it's not lighting and you don't want to change every material, you can "fix" this by post processing.

[deft marten]

I have some effects, so Post processing "enabled". Not for colors tho

Also FPS dropped from 450 to 110

Linear is set. Before and after

indeed something with lighting. When I disable my "sun" on previous version.. I have the black screen (like zero light). But on new version.. i still see a lot , something like during the night. looking

Look into ambient lighting. You always want some active in a 3d world.

[deft marten]

looking

in the meantime, this is what I mean... when I just starting Unity on newest version and make some other windows app active, I still see the "normal" expected colors/lighting (check screenshot) Game cam shows GOOD colors, while Editors cam shows a lot of blue. Once I open Unity, the game cam also becomes blue.

wonder what feature becomes active, once the Unity starts and active and makes colors too blue

Ok guys, found!

thank you very much. It was "intensity multiplier" in Lighting-Environment

[solved]

[warm hound]

HDRP
switching 3 lights 256 shadow map on-off
Why so much difference?

[stable acorn]

I've set up different quality modes in project settings (Built-in SRP) but upon changing them, the visuals of the game dont change? I can do it on URP since they are different render assets. But am i missing something for built in?

[stable acorn]

every light re-renders the object again every frame

[warm hound]

and without shadowmap they dont?

[warm hound]

found it was reflection probe

[warm hound]

oh even better shadows rerender even distance and frustum culled geometry, Niiiiice

[fresh meadow]

I just started up the URP prefab scene, does anyone know how to remove the foggy effect

[whole fossil]

guys please, I need your help. I've played around with overriding of volumes in the HDRP 10.3.1 and found out that I can't make it work as I think they should work. I described everything on the forums, but posting it here because maybe there is some explanation or I am doing anything wrong. I would appreciate anyone taking a look: https://forum.unity.com/threads/volumes-overriding-problems.1070807/

basically: scene loaded additively in the editor doesn't look as when opened single even if the primary scene is unloaded

[rain tide]

Hi yall, so I've gotten a test scene up and running to develop ReShade shaders in. Looks great, runs fast, all hail sponza. However, to have full testing functionality, ReShade needs to be able to see the depth and normal buffers, in addition to color. And since I'm a novice, I'm not sure how to expose those so injectors can pick it up. I've looked through the settings and I just haven't found it yet. TL;DR ReShade isn't getting anything for depth or normals, what bit should I be checking. Thanks! :)

[hardy wyvern]

I tried to create a toon shader but accentally fd up my project, how do I fix this error?

@ me when you have something to say to me

[steel minnow]

what would be the cause of these random white spots with hrp?

also appears on the low poly character model but not as noticeable

[waxen lantern]

HDRP? anyway, this looks like an aliasing problem. check out the HDRP docs here on AA / Anti-Aliasing
https://docs.unity3d.com/Packages/com.unity.render-pipelines.high-definition@10.3/manual/Anti-Aliasing.html
in addition to a general AA method above (that you will first need to enable on the camera,) this material property can be used in conjunction to help with specular highlights and grazing angles that can cause "white spots" in particular:
https://docs.unity3d.com/Packages/com.unity.render-pipelines.high-definition@10.3/manual/Geometric-Specular-Anti-Aliasing.html

[cunning solstice]

How can I change the values of the overides of the post processing volume in URP using code?
im doing

public Volume volume;
DepthOfField dof;

Start()
{
  volume.profile.TryGet<DepthOfField>(out dof);
}

but i get an error saying

The type 'DepthOfField' cannot be used as type parameter 'T' in the generic type or method 'VolumeProfile.TryGet<T>(out T)'. There is no implicit reference conversion from 'DepthOfField' to 'UnityEngine.Rendering.VolumeComponent'.
can anyone please help?

[dawn sorrel]

hey, im using the experimental 2d renderer and also a pixel perfect camera with a normal camera and the render wont support camera stacking, any suggestions?

[turbid matrix]

@cunning solstice that should work, although you left out some code

(should be void Start)

@cunning solstice for example this works for me: ```cs
using UnityEngine;
using UnityEngine.Rendering;
using UnityEngine.Rendering.Universal;

public class test : MonoBehaviour
{
public Volume volume;
DepthOfField dof;

void Start()
{
    volume.profile.TryGet<DepthOfField>(out dof);
    dof.mode.SetValue(new DepthOfFieldModeParameter(DepthOfFieldMode.Bokeh));
}

}```

[dawn sorrel]

Is HDRP going to eventually support Ray Tracing for AMD Cards? I may be getting an AMD Card here soon (if I can find one at least).

[scarlet hull]

It will, and highly possible also for new gen consoles and vulkan.
For AMD, it might already work, as the raytracing is using the DXR api.

[dawn sorrel]

Awesome, thank you so much. Now do you happen to have an AMD card for sale? hahaahah.

[scarlet hull]

haha, I guess only scalpers sale graphic cards at the moment 😅

[dawn sorrel]

I know right. I could understand 100-200 dollars more, but dang. 600 card selling for 3,000 lol

I was on Ebay earlier and hahaha people putting up a bunch of fake GPU's for sale (a box with a letter in it) for example so the bots buy them lol

[turbid matrix]

would be tempting to try to buy new gpu just to see if one gets it on some sane price.. and then sell old gpu for premium

could get close to free upgrade

[tranquil saddle]

So I'm reading a lot of raving reviews about Amplify Shader Editor, many of them mentioning solid compatibility with all Unity's different render pipelines.
But I'm using URP in combination with ShaderGraph on Unity 2020, and so far these all work nicely together. Is there still something to gain for me by using Amplify, or am I perhaps better off using what Unity provides natively?

Any thoughts are very we;co

*welcome

[elder merlin]

there's less of an argument for Amplify in URP but it's still got more features then the shader graph, though at a level that you might not need. So if you get the results you want with shader graph, just use that

[spare marten]

Hi! is the are way to use the shader graph without using urp or hdrp?

[indigo summit]

i don't think so

last time i check

[spare marten]

ow, ok, thanks!

[indigo summit]

out of curiosity is there gonna be any improvement for volumetric fog with moving light tho?

right it's just weird for any moving lights

[dawn sorrel]

Is there a reason why HDRP Fog set to 1 distance isn't covering the skybox correctly? It seems unnatural to see trees highlighted from the fog lol.

[grizzled flame]

I was curious about this today and realized that is indeed possible to switch between URP and HDRP at runtime!
https://docs.unity3d.com/Manual/srp-setting-render-pipeline-asset.html

You can set the Render Pipeline Asset using C# code. You can run this code in Edit Mode or Play Mode in the Unity Editor, or at runtime in the built player.

Because SRP is highly configurable, changing the active Render Pipeline Asset can result in a very minor change, or a very large change (such as switching from URP to HDRP). The performance cost of changing Render Pipeline Asset at runtime varies accordingly.

I wonder if it would ever make sense to do this, for example to support a wider range of target devices

[tawdry garnet]

@grizzled flame the issue with swapping render pipelines at runtime is you'll need different assests/materials/light backing ect

[grizzled flame]

Oh yeah I recognize this.

I'm just pleasantly surprised that it's an option anyway, even though it will be a metric ton of extra work

[bleak otter]

Post Processing V2, version 3.0.3, fourth(?) post processing stack for Unity 🤓

[grizzled flame]

Still less confusing than the UI stuff imo

[spice prairie]

Are UI buttons supposed to work with raytracing?

[turbid matrix]

@grizzled flame it's always been possible to do this.. and it's always been pain 😄

I've done proof of concept protos of this in the old LWRP days and recently with URP / HDRP combo

what is nicer now is that if you only use shader graphs, you can now target both URP and HDRP with same SG, so you don't need to swap the materials between URP and HDRP anymore if you only use SG shaders

lighting, volumes etc are still a bit of a mess and you have to redo this all for each RP

I also had trouble with HDRP high intensity lighting where HDRP exposure values leaked to URP side when swapping - despite URP isn't supposed to even have concept of exposure in same way

(missed the comments earlier)

Unity is supposedly making the URP and HDRP coexist better now but I haven't tested how it's on recent 2021 versions

what I see in github is more like unifying the menu look and feel though, I haven't really seen much work that actually merges these so you don't have to reconfig for other

so my assumption is that even with latest alpha, you still need to have separate and additive URP and HDRP scenes that load SRP specific cameras, lights etc

would be lovely if someday we could just let the URP and HDRP component data things coexist gracefully

[whole mantle]

After installing URP my map gets blurred like this and my pc freezes. Does anyone know what to do? Today is my deadline and Im getting really desperate

[whole mantle]

Or is there a possibility to switch back to the Standard Render Pipeline Asset without turning my map pink

[turbid matrix]

sounds like some lessons were learned today..

use version control. don't make dramatic last minute changes

there's no easy way to roll back unless you have some kind of backup or version control of the project in state where it still used built-in renderer

hard way is to just remove urp and swap the materials to standard shaders manually

you may need to reassign some textures to materials too

@whole mantle

[whole mantle]

thanks for the fast reply

the issue is, I would leave it how it is now but i cant work with my map at this state

its extremely blurry whenever i move around with the hand tool and my pc gets fucked up

@turbid matrix

[turbid matrix]

no idea on individual errors

[static locust]

Anyone has any explanation on why changing vertex colors on a mesh changes how many vertices that mesh has on import, when generating lightmaps within Unity?

[scarlet hull]

If two triangles have different colors, then the vertices they share are split.

It works similarly as for normal and uvs

[static locust]

but, how is that visible only if generating lightmap uvs? is that because a further UV channel is generated?

[scarlet hull]

I'm not sure to understand. Generating lightmap uvs will certainly add vertices for the new uv channel.
Having "splits" in vertex color will also add vertices.
Are you saying that without vertex color you have more vertices with lightmap uv on, than without, but you have the same number of vertices with and without colors, without lightmap uv ?

[static locust]

the thing is; i painted over a mesh with polybrush, then I realized the "generate lightmaps UV" wasnt checked on it, and when I turned it on the additional vertex stream was broken because the two meshes now have different vertex counts

[scarlet hull]

(I'm confusing myself trying to write that down)

[scarlet hull]

Yep, this is highly possible.
Once you've enabled lightmap uvs, it created new vertices, that broke the triangles index "map" and as such, broke the vertex colors.
I guess you'll have to re-paint the object.

[static locust]

• I have two meshes, one with vertex color, one without
• the meshes are exactly the same a part from that (same vertex count, same vertex position etc)
• on import, if "generate lightmaps" is off, they have the same vertex count
• on the contrary, if i turn it on, they get different counts

[static locust]

ok i see

i really hoped i would get some workaround

as we're here, any idea why a cutout shader should bake lightmaps as it was fully opaque?

[scarlet hull]

Hum, should work. I don't remember if there is a keyword to add to the shader or something

[static locust]

Might the wrong outline be a symptom of it?

[scarlet hull]

Likely possible

[static locust]

In which part of the documentation should I have a look at? (I'm asking cause i couldn't find it myself 😦 )

[heavy pumice]

most of my cpu usage is others

how can i make it less

[scarlet hull]

What RP are you using ? How did you make this shader ?

[static locust]

URP, I made the shader with Amplify

Ideally, it should be the same as the unity standard URP shader, just made with nodes (so i can use it as a template)

[scarlet hull]

Why not shadergraph ?
I'm not sure if it's a settings that is in amplify to toggle, or a keyword that need to be added (I've seen that for dither cross fade for example)

[static locust]

Because I started with Amplify before Shadergraph existed and because Amplify supports custom nodes 🙂
That's not the matter though, in the end they both output shader code, so I'm just looking for the setup that unity needs in order to use cutout data for light baking

[scarlet hull]

Try checking if the resulting material/shader has the keyword "_ALPHATEST_ON" .
IDK if will have any impact, but It's my first guess.

[worthy totem]

I haven't seen forward+ yet but I haven't looked much into URP branches either

@trim bone

forum post: https://forum.unity.com/threads/materials-changed.1073015/

eh, the same thing over and over again 🙂 @lusty sedge - upgrade matrials only works for standard shaders. Besides that you have to upgrade them manually

[lusty sedge]

Is there a video/documentation to upgrade it?

I have no idea how this material was made since it was from the asset store

[whole fossil]

no, there is not. Since you don't know how that material was made - who is supposed to know then if it should be automatically upgraded?

[indigo summit]

if that the case then the author of the assets should know or update the asset to support SRP

Has anyone tried rendering to texture with HDRP? I get massive GPU memory spikes

[unreal fog]

Hi

Why ?

I am using HDRP and cannot understand why my game mode is screwed like this 😦

It seems all camera settings are good

Camera preview is also good

[deft oar]

I'm using HDRP 10.3.2 with Linux and I've noticed that the HDRP/Lit and HDRP/Unlit shaders are broken. The lit shader error references a 'UnityRaytracingMeshUtils.cginc' which I believe is a typo as a UnityRayTracingMeshUtils.cginc (with a capital 'T') does exist in my core shader includes (Home/Unity/Editors/2020.x/Editor/Data/CGIncludes). I went into that folder and copy/pasted the file and fixed the T, which made the issue for Lit go away, but there was some additional error for Unlit as well saying it couldn't open 'AtmosphericScatteringRayTracing.hlsl'. I've tried this on both 2020.2.5f1 and 2020.3.0f1 LTS, but they both have the same issues. I've also tried reimporting the packages and deleting the cache to no avail. Does anyone have any suggestions?

[fast harness]

Hey guys

How can I adjust volumetric fog in unity

[deft oar]

@fast harness Are you using HDRP?

[fast harness]

when you are choosing what type of project you want

I selected urp one

[deft oar]

URP doesn't natively support volumetric fog afaik. You can adjust the fog under lighting settings, though by going to Window > Rendering > Lighting

[fast harness]

@deft oar where in lighting

nvm found it!

[deft oar]

Great! For those that might look for this in the future, here's a screenshot

[fast harness]

@deft oar Thanks so much!

Im making a very orginial game called minecraft

And the fog was very ✨ annoying ✨

[deft oar]

@fast harness happy to help! Good luck with the voxel chunking 🙂

ah that was

f u n

but most of the hard parts such as voxel and chunk mapping are over

so im in the fun biome and terrain stage

[keen pivot]

has the changes to unity lighting in HDRP from 2020.2.4 onward been discussed here?

the 'why is everything now kinda blue' issue

i see it was mentioned on the 07/03 and kinda just blown out

or 03/07 to my american friends 🙂

[scarlet hull]

The default sky in HDRP has a very high intensity, Set you lights intensity accordingly.
Tipically, a directional light that acts as a sun is around 80 000 lux in intensity.

@keen pivot

[keen pivot]

what i'm more interested in though, is it a bug, or a change? fixing it isnt a problem

what was once a perfectly lit scene is now wrong, so if i spend a long time righting it, then it gets bug fixed i'll be trying to work it out again

you haven't specifically said, the default sky intensity/temperature has been changed going forward...if you see what i mean? 🙂

interesting, once scene affected doesnt have a sky

but it also doesnt explicity not have one

okay so i've added scene settings with visual environment skytype set to none

my lighing settings have no static lighting sky, never did

but that scene also went blue tint when i upgraded

its a menu scene

3.141593 lux, 6000K

realtime directional light

so my original query remains i guess

[indigo summit]

Hey guys, who make/manage HDRP Custom Passes repo?

i have a question about one of the example pass

is the FPS Pass are completed or it is still WIP?

[turbid matrix]

that would be @woven sonnet

[indigo summit]

mostly i'm wondering it seems the custom pass are not working with screen space effect

[scarlet hull]

Even if the scene doesn't have a sky set in a volume component, there is a sky in the default volume component, that you can edit in the project settings.

[keen pivot]

So my setting a new volume with no sky doesn’t override that?

Okay, we’ll I’ll play with that tomorrow I guess

I downgraded back due to all the prefabs dying on me but that was a few versions back

Backup, repent and retry I guess

[tall bobcat]

Actually mb this would probably be a shader question

[woven sonnet]

Yes, it's me 🙂

is the FPS Pass are completed or it is still WIP
I wouldn't say it's completed because it doesn't work with SSAO, Subsurface scattering and other effects that uses normal or depth buffer. The current approach is only rendering the objects in the Forward pass, I think it'd be possible to add another pass to render the object in the depth pre-pass so these effects are correctly applied to the object (like this example: https://github.com/alelievr/HDRP-Custom-Passes#render-with-normal-buffer).

If you're trying to render an object with an FPS cam effect, you can also use ShaderGraph with vertex shader modification to apply a different FOV to the object but it's more complicated to setup.

[main rune]

o/

Anyone know what channel the Parallax Occlusion Mapping node uses on the input texture

It looks like it's using more than just my red channel, which is an issue for me

Hm, also do the UVs need to be oriented in a certain direction for POM to work properly?

[scarlet hull]

It should be only the red channel.
But the channel might be affected by the other due to compression settings ?

[scarlet hull]

Should not.

[main rune]

Strange

POM is pretty flip floppy for me, sometimes it looks great and sometimes it looks like it's both raised and lowered at the same time

I've got it setup to take input from a render texture that start at r=1 and lowers that value in damaged areas

Unless it has issue with values outside of 0-1

That might be a cause?

For example:

Left and right in this video look terrible, but up-down looks fantastic

https://puu.sh/HoH7D/596b4a637b.mp4

You can see the height map in the bottom right

Hm, it actually seems like the UVs on the mesh being weirdly flipped/aligned could be an issue

The orientation does matter smh

I don't know how that works for faces on the third axis though, considering UVs are 2D

It seems to want an 'up is right' orientation?

[main rune]

Not even. The quads are oriented to the right now and look fine, but the triangles on the beveled cube are moving incorrectly with the parallax

I doubt it's a unity issue because UE4 did the same thing IIRC

What does it want from me??

[main rune]

Figured it out... Unity by default recalculates tangents and it recalculates them incorrectly

[dawn sorrel]

is it possible to add HDRP/Tesselation Shader and have it work in worldspace positions?
So adding 4 planes in a 2x2 position would act as if they were 1 plane, making the heightmap and albedo texture continous across edges?

[indigo summit]

So technically speaking we just need to combine those custom pass?

[woven sonnet]

Yes, it should fix the screen space effects part but you would still miss some stuff like subsurface (which is probably fine in most cases)

[indigo summit]

i guess the character should wear long sleeves and gloves then for now 😅

[woven sonnet]

Yeah, that's a bit sad but right now the ShaderGraph approach is the only thing that will support everything

[indigo summit]

was looking a way to prevent clipping without having to render small object

[woven sonnet]

In that case the simplest you can also use a custom pass to force the rendering of your object in the depth buffer with a ZTest to always and then let the normal rendering do the rest of the job. But I'm afraid that approach will pause problems with SSAO because you're creating a hole in the depth buffer so I think the object will be darkened whenever it intersects the geometry.

A simpler way would be to use a transparent material for your object with ZTest to always, that way it won't mess up with the depth buffer.

[indigo summit]

you mean in DepthTestOverride?

[keen pivot]

i just went from 2020.2.3 to 2020.3.0 and not had the problem this time. so perhaps it was a bug but if you had gone to 2020.2.4 you ended up stuck with it.

is there something im missing out on? the latest downloadable version of HDRP is 10.3.2

i also see this on unitys docs site

Hello, I think i have a potential issue with the URP interfering with my particle systems. I made a shader using the URP and my particle systems that once worked before don't render properly as shown below. How do I fix this? https://gyazo.com/1ebbbdc70f37787bc1a35986543eb58b

[turbid matrix]

@ocean salmon TAA would help on that

[ocean salmon]

Thanks, I tried but still

I tried with all settings on TAA, I can make it stop flicker but makes everything blurry

[turbid matrix]

could try some shaders with specular antialiasing

or do some material hacks to lessen it

TAA does kinda blur things yes

Does anyone know if Ray Tracing will work on Vulkan? I'm getting a 6800xt here soon and just curious if DX12 is the only support for it in Unity.
Just saw this and this is why i'm asking.

[turbid matrix]

@dawn sorrel there's no vulkan raytracing implemented in Unity atm

[dawn sorrel]

Alrighty, sounds good. Now I know 🙂

[split fjord]

Is there a way I can apply render scaling to a project without the need for a scriptable render pipeline?

[dawn sorrel]

Does anyone here have a 6800xt? If so how's the performance with DXR?

[ocean salmon]

Thanks, let me try that one

[ocean salmon]

@turbid matrix It is no better with that shader

https://i.gyazo.com/8bd25e18e13dac4a5cabc42cd647da4e.gif

Any other idea?

[turbid matrix]

not really no.. I mean there's the old school texture hack for adjusting the smoothness map with normal map to make it rougher at the sharp edges, it's similar idea as on that shader you tried, the shader just implements it for geometry where textures can affect the specular aliasing elsewhere too if there's a big change in normals

your gif looks more like specular aliasing from the mesh edge

people usually just use TAA to fight this or all these other hacks if it's VR game where you may not want to use TAA and use MSAA instead

[ocean salmon]

How does everybody works around it?

This seems to be a common issue but I dont know how everybody resolve it and still use standard shaders

[ocean salmon]

Anybody else would have an idea on how to fix that Flickering issue? I appreciate your help

[waxen lantern]

like @turbid matrix was saying, you can also modify the material pbr texture maps like the normal map. or even modify the mesh geometry.

[olive tiger]

Hi all, just joined looking for help on the deferred shading pipeline in Unity! I'm trying to implement an effect using data from the GBuffers, however I'm finding the process regarding lighting data a bit confusing. I understand that there's a light buffer rendered during the deferred pipeline, meaning I can sample from this instead of having to pass in scene light data in uniform buffers, however whenever I try sampling from this I get incorrect lighting data (e.g. changing the scene light colour causes no change). Is there anybody here who knows more about this? Thanks!

[waxen lantern]

what render pipeline are you using?

[olive tiger]

Deferred, if that's what you're asking?

[waxen lantern]

deferred shading is a lighting / render path, not a render pipeline

forward or deferred is an option within most and soon all render pipelines

[olive tiger]

oh, I think I know what you're referring to now.

Like the Universal Render Pipeline and the other one the name I can't remember

[waxen lantern]

https://docs.unity3d.com/Manual/render-pipelines-overview.html

[olive tiger]

I'm using the Built-In Pipeline

[waxen lantern]

@olive tiger it's from 2017 but this is still a good resource to learn more about the deferred render path for the built-in render pipeline https://catlikecoding.com/unity/tutorials/rendering/part-13/

wrong link

okay there fixed

[olive tiger]

Thanks! It's just this lighting stuff I'm grappling with right now.

Everything else I think I understand

[ocean salmon]

@waxen lantern I see, I dont understand what modifications would prevent it from flickering

Most of the objects flicker anyway, Im guessing it is not an issue with the meshes since most of them have it

[waxen lantern]

@ocean salmon these modifications

the smoothness / roughness map, and the normal map. the vertex normals of mesh geometry itself also contributes to the normals.

[waxen lantern]

it's unfortunately not always that simple. the person or team that made these meshes and material maps may have not been able to test them in all render pipelines, render paths, anti-aliasing methods, lighting conditions and scenarios.

e.g. if you use a forward render path and and crank up MSAA to 8x or higher these artifacts are usually a non issue

[ocean salmon]

I see, but it is not the material or bumpmap, the flickering is hapening on all edges

[waxen lantern]

but there are trade-offs to using forward rendering vs deferred

[ocean salmon]

even on a simple cube with the default material

[waxen lantern]

that's besides the point

[ocean salmon]

I also tried with MSAA at 8x and still get some small flickerin =/

I you are right, just found out disabling the normal map will stop the flickering

so what kind of edit I need to do to the normal to avoid the flickering?

[waxen lantern]

this is an issue that can happen on any mesh and material given a high enough smoothness value and / or steep viewing angle, at "grazing" angles

because of the fresnel effect which makes surfaces look smoother at grazing angles

[ocean salmon]

I see, thanks for helping find out the root of this

Im still confused on what edits I need to do to the normals

[waxen lantern]

so yeah it's a pain we all have to deal with and mitigate in some ways at some point, especially with physically based rendering (PBR) and deferred rendering

[ocean salmon]

yeah, I use Deferred and these are PBR Textures

but tried Forward too and had the same issue

Sorry maybe you already answered but I didnt get it, I still dont know what modifications I need to do to the normal map to avoid this flickering

[waxen lantern]

@ocean salmon for example, see this reddit thread not even talking about Unity, but just some generic PBR renderer someone made from scratch with OpenGL https://www.reddit.com/r/opengl/comments/9ivo7t/specular_aliasing_for_my_pbr_renderer/
the first response is "Classic PBR artifact, you need to get yourself some temporal antialiasing!"

but no method is perfect, it only reduces / mitigates the issue

[ocean salmon]

I understand that, problem for me is that TAA does not fix the issue

[waxen lantern]

you would literally paint the edges of the smoothness / roughness map in photoshop or other image editor to be less smooth, more rough.

or paint the edges of the normal map in photoshop or other image editor to point the surface normals to a direction that is flatter or ultimately facing the camera more (rather than perpendicular to the camera.)

[ocean salmon]

but the one causing the flickering is the normal map, should I still edit the other maps?

[waxen lantern]

it's a trade off yeah. nothing can technically "fix" this issue at its core, given these render methods. it's just something we have to try to mitigate and reduce the visibility of with various treatments. some that work better for certain use cases and scenes, lighting conditions, performance budgets, art styles, etc

[waxen lantern]

it's not one thing causing the issue, there are many factors here.

[ocean salmon]

I see, which render methods would not have this defect?

[waxen lantern]

I mean the render methods that are used industry wide. like, sure, you could avoid this by not using physically based rendering at all... but then your materials will not look photorealistic.

and also at a certain point if you crank up MSAA high enough with Forward path, or use SSAA the problem could be imperceptible, but at a great cost to performance.

so if you want the best of both worlds, looking how you want and optimized performance, you have to settle for some combination of anti-aliasing (MSAA, TAA,) geometric specular anti-aliasing and/or other methods like modifying the assets PBR texture maps and material properties to mitigate the issue

often many of these methods are used simultaneously to get a desirable result

@ocean salmon we also someday may not have to worry about this rasterization problem at all with 100% "path traced" real-time ray tracing and/or differentiable rendering but that's still something like ~5 years from being feasible and ~10+ years away from being widespread.

in the meantime we just have to apply these various band-aids 🩹

[ocean salmon]

I see

for now just scaling up the normal map by x2 solved the issue

[waxen lantern]

even with a game that uses real-time raytracing today.. it's not fully ray traced, it's a hybrid method of rasterizing parts of the frame like the albedo / base color like we always have, and using raytracing only for certain effects like reflections, shadows, ambient occlusion, etc

[waxen lantern]

that's great!

[ocean salmon]

yeah, thanks for all the help

wouldnt have figured it out by myself

[indigo summit]

it break the depth rendering tho

[silver vortex]

Should I call DrawProceduralIndirect only once per update? Everything works for single object I process in compute shader but if I call it per object only one is rendered.
How do I make it work on all objects?

[worldly cape]

Ok so I've narrowed it down to: DirectX12 is what's causing my black screen flickering when trying to use HDRP x DXR.

If I switch it to DirectX11, no more flickering - but also no more DXR then.

[wraith pendant]

Hi, I have a problem with my game, my WebGL build doesn't launch the first scene and instead I have the errors that we can see in the following screen.

I think it's maybe related to URP, or the fact that I'm using custom shaders? I added them to the "Always include shaders" option, but my first scene (which doesn't contain any of these shaders anyway) doesn't load.

Is there an extra step I could have neglected ? I couldn't find many relevant things on the internet.

[olive tiger]

Done a bit more reading on the topic - am I correct in assuming that scene light data is not accessible in shaders?

For context - I'm writing a deferred shading effect that requires scene light data and am figuring out what the best way to access it is.

[waxen lantern]

i'm not sure on this exactly, there might be a way. but keep in mind there are hard limits to how deep you can modify and extend the built-in render pipeline. that's why the scriptable render pipeline API was developed.

[waxen lantern]

what render pipeline are you using? and a code example would greatly help in answering this question. (there is more than one .DrawProceduralIndirect method, and other context that without being known, make this question ambiguous / unanswerable. or possibly irrelevant to the exact problem and solution.)

[waxen lantern]

not sure if it will work in your case but see the very end of this thread for a possible solution from a dev that encountered a similar issue: https://forum.unity.com/threads/webgl-dev-mode-not-giving-human-readable-error.1037656/

[wraith pendant]

sadly i have already try it (though i didn't find the Decompression Fallback option in my Unity)

but it seem this user uses a version ahead of mine, i can try update to 2020

[wraith pendant]

(it didn't work)

alright i find the solution here : https://www.reddit.com/r/Unity2D/comments/l3smh4/i_added_universal_rp_to_my_game_and_now_on_only/

I simply had to activate "Post processing" on the main camera.

[craggy crane]

Hey, I was wondering if someone could help me figure out if this is a bug or a feature.

If you try and sample the "additional light" shadowmap with URP, using an unlit or fullscreen shader, (e.g. with GetAdditionalLight() or AdditionalLightRealtimeShadow(), SampleShadowmap()) the shadows appear in the editor but vanish in the build. I've tried compiling with: #pragma mult_compile _ADDITIONAL_LIGHTS_VERTEX _ADDITIONAL_LIGHTS_ _ADDITIONAL_LIGHT_SHADOWS, multi_compile_instancing multi_compile_fwdadd_fullshadows. Is this expected behavior?

[craggy crane]

I checked with a basic shader which may as well be lit, but the place that I'm actually needing this is for a volumetric lighting renderfeature. I'm assuming something somewhere gets left out of unlit shaders in the build?

[keen pivot]

just thinking aloud, but i read that the URP is going to be the default renderer soon, but the definition of high end is going to change as things develop right? so are current consoles (PS5/XBSX) considered URP or HDRP targets? are we not looking at a scenario were URP wont really be required? i dont know how it works under the hood but i feel like the pipelines should be compativle with each other just with high end features turned on and off perhaps? then you dont need to choose what rendered you want, if just adapts.

i feel like i'm using HDRP now due to missing URP features, URP is added most of the features i need in due course, but as that day approaches where i can use it, so does the day where i dont need it. does that makes sense?

i'm not complaining, just wondering how others see it. compaitble shader grahis with nodes that you can choose depending on if that feature is enabled in the SRP would be handy i guess and solve a lot

Cave Johnson we're done here, chariots chariots. 🙂

[waxen lantern]

current consoles are considered targets for both URP and HDRP... URP for projects that need to scale down to mobile, or have a non photo-realistic rendering style.

remember HDRP isn't a superset of URP, it's also strictly physical based rendering. URP is much more flexible in easily customizable lighting for non photorealistic rendering

[keen pivot]

i dont think too many games could be considered photo-realistic

hmm, yeah i think i still have a major lack of understanding

HDRP is just so damn easy to work with tho

little effort in, really nice results out

[waxen lantern]

then your use case(s) must be a good fit to what HDRP is tailored for

[turbid matrix]

I wouldn't treat URP as non-photorealistic (if that's even a thing)

both are physically based renderers

[keen pivot]

i do plan in the next few fews to side-step my project and port it to URP

you know, for science

[waxen lantern]

@turbid matrix URP is PBR by default but it has much more support for NPR use cases. HDRP lighting isn't meant to be customized for NPR at all, URP is. Unity devs have made clear statements on this. i can dig it up later https://en.m.wikipedia.org/wiki/Non-photorealistic_rendering

[keen pivot]

i hoping to find out soon how HDRP runs on the current gen consoles, the compute units thing makes it hard to just compare by gpu speed

my friends 2060 toasts my 1070 probaby due to more compute units i guess

[waxen lantern]

@keen pivot URP is also a much simpler lighter weight RP so many teams / studios find it easier to work with from a workflow perspective. not quite the "light weight" RP it once was but still relatively compared to HDRP

[keen pivot]

nope, i should have checked that before making that comment

i'm wrong about the specs

[turbid matrix]

ah, HDRP is all about physically based

[keen pivot]

hdrp is mostly consistent, you tell it things and it produces what you expect

thats my experience anyway

[waxen lantern]

yeah, this is the discussion i was thinking of: https://forum.unity.com/threads/support-for-custom-lightning-in-hdrp.793416/

basically Unity devs responded saying that HDRP is PBR only, URP is PBR or optionally NPR

[keen pivot]

NRP meaning? not really proper?

oh

npr

damn

i cant read today

[waxen lantern]

@keen pivot these design choices could change in say ~10 years and HDRP or some RP based on it could be the default RP, say, when even cheap mobile devices have realtime raytracing hardware. but it's pretty speculative

[keen pivot]

so like, RT is HDRP only right?

[waxen lantern]

yeah, currently

[keen pivot]

so its going to see a lot more game usage than german car adverts i guess

[waxen lantern]

but you could make your own SRP with Unity's raytracing API,,, or even use the raytracing API with built-in RP

you're just on your own. HDRP is just the only RP that Unity supports real-time raytracing for out of the box

[waxen lantern]

that's pretty funny, though. i might start calling NPR "Not Proper, Really" just to be cheeky

[waxen lantern]

with this console generation supporting it yeah i hope so anyway

[keen pivot]

thats an intersting point though

when i was trying to make a water shader as there was nothing for hdrp, i looked at the boat attack thing and it was WAY beyond my abilty

which comes back to HDRP making me look like a hero because of what it does for me

[turbid matrix]

related https://forum.unity.com/threads/dxr-raytracing-effect-from-scratch.794928/

also linked there: https://github.com/INedelcu/PathTracingDemo

that's using built-in renderer

[keen pivot]

i dont need the RT but where i was going with it is that there are features of HDRP that are targetted for high end rendering and not for games, i cant tell from looking at the nodes or features what to avoid or lean towards

[turbid matrix]

I'd love to get RT for URP

basically, I'd love to get most of the HDRP features for it 😄

[keen pivot]

i have two particular areas where i use a stacklit shader and i read the other day thats a no-no for games

[waxen lantern]

Shader Graph has support for building one shader graph to target multiple RPs right now actually.

[keen pivot]

it does?

i saw quality options

[turbid matrix]

yes

just set the targets you want and boom

[keen pivot]

well that'll be apparentlt when i do my URP port then i guess

[turbid matrix]

it's been in since SRP 9.x

[keen pivot]

and dead handy too

[turbid matrix]

I've used it on my URP + HDRP runtime swap testing

[keen pivot]

well i did try on SRP9 and couldnt escape the magenta nebula

[turbid matrix]

you can mostly keep the materials intact regardless of the SRP with that approach

[keen pivot]

i'm looking at the XBO/XBSX devide really

[turbid matrix]

you have to have both URP and HDRP installed to be able to target both on the new SG setup

[keen pivot]

i didnt realise how underpowered the XBO is for HDRP

or in general really 😛

when you have a large amount of scene in play it wont cope

[waxen lantern]

@keen pivot yeah because it's gonna be streamed down from XCloud anyway right? ¯_(ツ)_/¯

who needs local hardware

[keen pivot]

yeah or cloud compute does all the work while you watch american football as i recall

[waxen lantern]

😆

[keen pivot]

that was a weird day, it really was

[waxen lantern]

sorry, apparently it's *Xbox Cloud Gaming (formally announced as Project xCloud and formerly known as xCloud)

[keen pivot]

sounds about right

so 2021.1 looks like quite a lightweight release as far as HDRP goes

bit like 2020.1 was

[waxen lantern]

@keen pivot yeah.. 2021.2 seems a bit bigger for SRPs though. in particular I'm looking forward to ShaderGraph support for Vertex ID, Instance ID, and Custom Interpolators between Vertex and Fragment stages. Which is a huge step towards Shader Graph being truly viable. also VFX graph support for any shader graph material, (no longer trapped in its own silly and limited VFX graph target render land.)

[keen pivot]

i understood a few words there

mostly the ones bewteen the complex ones

but i think thats material properties in a way

[lost skiff]

Why when i switch from ISO to prespective it looks like this...

And then when i swtihc it backit looks like this

There something im not getting?

[keen pivot]

does that happen if you turn the post process volume off?

[barren goblet]

in unity URP , multiple viewports seem to use the same script ?
want to have independent data, for each camera,
I store the PrevViewMatrix in the RenderFeature,
but, the GameView and SceneView share the same data

[vague anvil]

Is there a way to make a utp project without the default assets

[craggy crane]

You can assign different renderers to your scene and game cameras.

The scene camera will use the renderer marked "default" and the game camera can just disregard that renderer.

So, unrelated, but my experience with URP is that changing the light model is trivial, until something goes wrong, and then the learning curve is a cliff, where's it's all constantly-changing arcane incantations and nobody seems to know the "right" way to do anything. Reading through the actual RP code, documentation is quite sparse.

I still have no idea how to debug something that works in the editor and completely disappears in the build. All I've managed to learn so far with RenderDoc is that the shadowmap doesn't seem to somehow get flushed in the built version.

[plain mural]

how do i fix shadows looking like this in hdrp?

its for both volumetric fog shadows and ground shadows

[patent sun]

Is there any way to have more than 8 terrain layers in hdrp?

[turbid matrix]

@patent sun multiple terrains with unique 8 layers on each? if 3rd party solutions count there is always microsplat..

[rich compass]

Ok I am super confused, I can't seem to get CommandBuffers to actually work, at least in URP 11. I figured this will clear my main camera view to red:

commandBuffer.name = "Clear to Red";
commandBuffer.SetRenderTarget(BuiltinRenderTextureType.CameraTarget);
commandBuffer.ClearRenderTarget(true, true, Color.red, 1f);
Camera.main.AddCommandBuffer(CameraEvent.AfterEverything, commandBuffer);```
but it doesn't. What am I missing?

[rich compass]

Oh snap...command buffers aren't supported at all in URP 11. And there's no errors or warning to let you know. ffffuuuuuu

at least adding a command buffer to a camera isn't. it's not even planned to be supported

[civic flume]

Light probes seem off in URP vs built-in RP... I did a bit of googling and I guess objects that are lit by light probes aren't influenced by ambient color in the standard lit shader. Has anyone fixed this in a custom shader? Also does anyone know how to author a custom shader for URP? So far I've done it just by copying the lit shader and some of the files it includes - but I'm wondering if it would just be better for me to create my own render pipeline package based off of the URP package from - https://github.com/Unity-Technologies/Graphics ? My first attempt to do this failed and resulted in a bunch of console errors (cloning the repo, creating a new local branch and importing that branch as a package in Unity via the package manager and then removing the default URP package)

[waxen lantern]

curious where are you getting this info? do you mean in terms of an extensibility API for customizing URP without forking it ? all RPs use command buffers under the hood

if you're expecting custom extensibility to work in URP or HDRP like it does in the Built In RP (by adding command buffers directly to cameras) then that's the disconnect.

@rich compass Have you looked into URP's custom renderer feature API? https://docs.unity3d.com/Packages/com.unity.render-pipelines.universal@11.0/manual/urp-renderer-feature.html

[rich compass]

This is for mobile VR, so I don't want to use passes

Thanks tho!

My intention now is to subscribe to endContextRendering and execute a buffer in that context

[waxen lantern]

Yeah, it's ultimately going to help with authoring materials. the main takeaway is, ShaderGraph is a taking large step closer to being feature complete. That is, being able to author more complex materials with ShaderGraph that you previously could only author by copying and modifying (aka forking) shader code for the "Lit shader" in HDRP for example.

[keen pivot]

any news on stencil?

[waxen lantern]

This API seems related? And yeah forgive my lack of context on URP and mobile. I typically work with HDRP https://docs.unity3d.com/Packages/com.unity.render-pipelines.universal@11.0/manual/using-begincamerarendering.html

[keen pivot]

was it you who was doing some liquid type stuff in the vfx graph?

sure i saw something along those lines doing the rounds

[waxen lantern]

yeah

[keen pivot]

did it bear fruit?

[waxen lantern]

@keen pivot yeah. i made a custom vfx graph output context that writes particle data to a buffer that i use to generate a volume, that is then used to generate a mesh for fluid or any particles or point cloud really https://twitter.com/landon_vfx/status/1298024495962181632

@keen pivot It works in HDRP as well now though and can look like water with refraction, etc but not ready to share that yet

[keen pivot]

So, could you drop a physics object on it?

Or through it?

[waxen lantern]

@keen pivot not trivially but yeah, sure

[keen pivot]

makes hmmming noises, hmmmmingly

[waxen lantern]

it wouldn't be two way coupling though

i.e. colliders can move the fluid but fluid can't move the colliders or make them float

[keen pivot]

So it would ignore the object once it’s been triggered by it?

Oh, yeah

[waxen lantern]

not that two-way coupling is impossible but it would require a completely different kind of solver (like PBD or MPM instead of SPH.) that's getting a bit off topic here though as the rendering technique is completely independent of the simulation 😁

Hello, just upgraded to URP 11.0 and this is my error when making a new property in subgraph or selecting one, any idea how can I fix this? Thanks

[barren goblet]

in URP, if I want to have my custom camera data, e.g. PrevViewMatrix,
I should new data for each camera EditorCamera, MainCamera,

It's ok for now, but these data will become too big, history buffer, and ,,,,

😂

[prime merlin]

is there a way to control post process effects paramater inside a shader ( how to expose them) ? i.e ; bring LUT / color adjustment as an overlay on specific subgraph )

[eternal laurel]

Really cool. Care the explain the bit with the volume that is used to generate a mesh? Is it some sdf stuff or what? I always tought that with fluid sim stuff you use the particle data to drive verts in the mesh directly.

[iron flame]

disable contact shadow on direcetional light.

[rich spade]

in URP you can use shader graph to write a shader to do this, by utilizing an unlit graph and adding in custom lighting functionality you can make it do what you need. Assuming you have some knowledge in writing shaders it should not be too difficult there are tutorials and code snippets around the web to help with this.

[fair forum]

Hello people, i just updated my project from 2019.4 LTS to 2020.3 LTS, now my Postprocessing does not work anymore. Im using a URP.
I created everything in 2019.4, is there something diffrent since then?
Does anybody now what the problem could be?

[scarlet hull]

I don't remember when precisely this happenend, but if you were using the post processing stack V2 package, you will need to re-create your post processes using the URP built-in ones, that you can find in the volume component

https://docs.unity3d.com/Packages/com.unity.render-pipelines.universal@10.4/manual/integration-with-post-processing.html#post-proc-how-to

[keen skiff]

i tried creating a new volume, that did not change anything

[scarlet hull]

Double check all the settings mentioned in this doc page

[keen skiff]

it says "URP is not compatible with the Post Processing Stack v2 package.", how can i use a different Stack?

[scarlet hull]

I can not be more explicit that the doc page linked 4 messages ago where everything needed to set up and use the post processing in URP is explained.

Pay attention to the difference between the new Volume component, that is buit-in for URP and HDRP, and the "old" Post Process Volume of PP stack v2

[keen skiff]

ah yes, that was my problem. thank you very much!

[civic flume]

I know I can use shader graph but that wasn't really my question....

[rich spade]

well I'm a bit confused as to the actual question, as ambient color comes from the environmental section of the lighting which does affect standard lit shader. Unless you can demonstrate otherwise I believe it "works as intended".

[civic flume]

I'm talking about objects that are lit by light probes when using mixed lighting.

They appear darker when switching from the built-in RP to the URP - the ambient color is a guess as to why but I've found a forum thread discussing the same issue.

[rich spade]

It maybe more due to the lightmapper used, it would be nice to think that enlighten would be consistent (assuming you have regenerated since swap to URP) it may differ due to the pipeline differences. You could try the different lightmappers to see if they give any better results.
The other consideration is has the project changed color space from gamma to linear or vice-versa as this could impact.

[civic flume]

no color space changes - but I had that thought as well

lightmapper is an interesting suggestion - hmmm

this is the forum thread I was referring to btw: https://forum.unity.com/threads/urp-ambient-color.1020577/

[stray owl]

hi! somewhere in this chunk wherein i handle the gradient noise, artifacts are generated around visually intersecting objects

as you can see, refraction is wrongly drawn over this cube which is not below the plane with the shader...

if anyone could help - i believe it's to do with the screen position, but i'm not sure how else to do it!

also, if y'all could @ me if you help, cheers all! ❤️

[scarlet hull]

That's an old issue with refraction.
As you are probably doing refraction by using the scene color node, the shader is displaying "what is on screen", and doesn't care if it is behind or in front of the current rendered object.
If you want to avoid that, you'll need to do a depth rejection, by also getting the value from the scene depth node, and compare with the actual depth of the object. You can then decide to show the refracted color or not.
It will avoid displaying the cube pixels, but will result in holes in the refraction.

[stray owl]

@scarlet hull

right, thank you. would you be able to provide a link or explanation as to how i might do that? sorry, shadergraph newbie here! :P

[scarlet hull]

Use scene depth node with the same UV coordinate that you use for the scene color.
Compare with view position (https://docs.unity3d.com/Packages/com.unity.shadergraph@10.4/manual/Position-Node.html) .z value.
Use the result of the comparison to display refraction or not.

[stray owl]

alright, thank you buddy!

[last cipher]

hey all 👋 is there a reason this would work on mac but not windows? and is there a possible solution?

RenderTexture renderTexture = RenderTexture.GetTemporary(rtW, rtH, 0);
renderTexture.name = "_ColorBufferRT";  //id render texture for frame debugger
cmd.Blit(sunBufferA, renderTexture, mat, 1);
mat.SetTexture("_ColorBuffer", renderTexture);

it keeps trying to blit sunBufferA back to itself, according to the frame debugger

like i don't get why these would be different when the code is the same

[last cipher]

fixed it with a workaround. instead of bothering with that blit, i did

cmd.SetGlobalTexture(COLOR_BUFFER_PROP, sunBufferA);

@keen pivot well unity's enlighten license had expired and unity already had a functional in house light baker, so they only gap to fill was the real-time global illumination light probe system. which on the very high end was already starting to get filled by raytraced gi. my guess is because the in house probe real-time gi probes solution that is meant to replace enlighten real-time gi probes was / is going to take much longer to develop than expected, and/or misjudged the demand for real-time gi light probe system, so they decided to renew the license for enlighten to fill the gap.

similar to how the in-house dots only visual scripting graph was taking longer than expected (along with dots editor and rp features it is dependent on) so unity acquired bolt from ludiq to accelerate having a solution in the meantime. as a company, if you have a commitment to have a product or solution but are falling short of your goals or timeframe at a certain point you just have to "bite the bullet" and outsource or acquire.

[ember breach]

Well hopefully DDGI or Probe Volumes will come to replace this old lightmapping systems...

@scarlet hull i know "business politics" is the colloquial umbrella term but rarely are these happenings truly political. they are more often sociological, and logistical. perhaps even less interesting to some . 🤣 I actually find it all quite interesting, though. "Peopleware" by DeMarco and Lister is a great book on these topics

[keen pivot]

yeah, that's political all right. reason i said not interesting is that those elements are rarely something we need to be concern about. no-one is going to feel they need to explain the enlighten fees to the users 😄

bit if a combo though

as if a new solution was realised to not be really viable, its then technical

so this is five sentences i guess i've wasted

[waxen lantern]

i mean, it's very likely both

[keen pivot]

enlighten was phased out just as i got started

so for me its pretty much a new toy

it looks like a really really lightweight version of ray tracing for the underpowered masses

[waxen lantern]

yeah, it definitely helps fill a huge platform / performance gap for global illumination anyway. combine it with screen space reflections, ambient occlusion, and then you have a half decent proxy / fallback for real-time raytraced effects.

[keen pivot]

SSR doesnt work well for me, i think because its just not designed for what i'm doing

i have a top-down camera, and SSR has a angle / distance cut-off that means it doesn't show

i did find a setting to change and i had to set it massively high and then the frame time just hit the roof

[scarlet hull]

I think this is one of the worst scenarios for SSR 😅

[keen pivot]

yeah, it takes me a while to realise what cool stuff is meant for what application

reflection probe is holding up well for now

[scarlet hull]

If it's on planes, maybe planar reflections would be an option

[keen pivot]

yeah sorry thats what i meant

puddles, road, planes, all good

[scarlet hull]

When I said "planar reflections", it was in the context of a "planar reflection system", not just plane-ish thing set to reflect

[keen pivot]

indeed, i have planar reflection probes doing my bidding, i just forgot to mention the word planar as i dont use any other type right now

[scarlet hull]

oh, ok 😉

[keen pivot]

the scene is all present in one shot

so for me, a screen space reflection and a whole world reflection are pretty much the same thing

truth is i dont spend much of my time hovering in the sky or filming from drones to know what its supposed to look like from up there

a puddle reflection from up top is actually quite a boring thing

[civic stump]

question: in this documentation page it is said that it's possible to switch render pipeline at runtime quote: "or at runtime in the built player." Source: https://docs.unity3d.com/Manual/srp-setting-render-pipeline-asset.html does anyone have experience with that? It would be a lifesaver for my project to be able to have one scene play in URP and another with build-in render pipeline. I dont know much about the "depth" of Unity rendering so i can't check if this is possible or plausible.

Or to put it in a practicle scope: I need a scene with build-in render pipeline (Character selection) and then for the new gameplay scene switch to an URP scene. There could be a loading screen.

[turbid matrix]

@civic stump it's doable, not recommended though

why would you want to have that?

anyway, see the C# code part here: https://docs.unity3d.com/Manual/srp-setting-render-pipeline-asset.html

I have never tried to set null asset for that though so don't know how that will work, basically you don't have any asset assigned for that with built-in and with URP you assign URP's asset file to that

[dawn sorrel]

Hi all how to add or assign opacity map to an URP lit material?

[rich spade]

on the default lit URP shader, you set it to transparent and the alpha channel of the albedo texture is used as the opacity map. This is the generic norm, you could write your own shader and handle it differently if so desired.

[amber kite]

alright, now that I'm here, where do I get the real HDRP template? I wanna start messing with it some more, but the demo has so much in it, I'm not sure what the bare minimum, nice to haves, and completely unnecessary things are. the "tutorial" is no help either because it's just a link to a page that takes 4 paragraphs to say "hdrp uses some new rendering techniques and options. the demo will get you started"

any pointers, links, or so on would be greatly appreciated. I just wanna do it right and I can't seem to find any information- it's been a few hours of searching.

[dawn sorrel]

Thanks let me try that out...

[amber kite]

never mind found it

gah. this is dumb- we need a proper hdrp template or this thing's never gonna get properly tested by the community =3=

[scarlet hull]

I don't get what you mean by "we need an HDRP template" ...
We have one, when you create a new project, what more do you want ?

[amber kite]

well, I click that, and this pops up!

and it's filled with a bunch of assets and packages that I have to delete, so I have no clue what HDRP is, so I click on the tutorial, and it says "use the template as a reference"

[scarlet hull]

Ok, so you'd like a "blank" hdrp template ?

[amber kite]

I mean, I just made one

but really, until just now I had no clue HDRP was a package named "high definition RP"

that would be good to put in the tutorial!

[scarlet hull]

We don't really want to clutter the list of templates in the new project window, but we plan to change a bit the hierarchy of the HDRP template to separate the assets and the minimal settings, so you could just delete one folder to have a blank project with HDRP pre-configured.

[amber kite]

I think that after 3 years, we just shouldn't need a tech demo without a proper tutorial to be the only way for a new user to access it.

it's been years! you'd think people would just want to get on with their lives and not have to delete the butterflies as part of their workflow.

it's a template where most of the assets need to be deleted first,
a tutorial which is just a link to documentation,
and a demo only available to people who clicked the button to make their own game.
it fails as all three.

so yeah, don't clutter the list. as someone returning to unity after a long hiatus, it was incredibly confusing. just give me a blank template, and a .txt that lists what the pre-installed packages do, and what the non-default settings are and do.

[dawn sorrel]

i think the templates are just unity trying to be like unreal

[broken lichen]

Isn't the default UE4 template just a white cube on a white floor with a skybox?

[amber kite]

^

I really wish someone told me HDRP was just a package that gave unity a new renderer and settings before I took 6 hours to find a single youtube video that explained how to find it

[broken lichen]

I'm curious, what did you think HDRP was?

[amber kite]

a SET of packages and necessary assets.

after all, the template had like 14 of them.

and the "tutorial" said to refer to the template.

so I was super confused about which ones made HDRP work and which I could delete

[broken lichen]

Technically, HDRP is a set of packages. It has these dependencies, which are automatically installed along with it.

{
"dependencies": {
    "com.unity.modules.video": "1.0.0",
    "com.unity.modules.animation": "1.0.0",
    "com.unity.modules.imageconversion": "1.0.0",
    "com.unity.render-pipelines.core": "12.0.0",
    "com.unity.shadergraph": "12.0.0",
    "com.unity.visualeffectgraph": "12.0.0",
    "com.unity.render-pipelines.high-definition-config": "12.0.0"
  },
}

[amber kite]

^this should be in the documentation

[celest ice]

is something broken with assigning scripts to custom functions in shadergraph 12 / unity 2020.2.0a8?

it only lets me drag in a 'Text Asset'

[broken lichen]

What do you mean scripts? Like a C# script?

[celest ice]

but Text Assets don't include .hlsl or .cginc, so I get

sorry, i mean assigning shader code files

[broken lichen]

.hlsl and .cginc are imported as Text Assets

[celest ice]

hmm mine aren't :/

it shows as

[broken lichen]

Huh, that looks new

What Unity version are you using?

[celest ice]

2020.2.0a8

[broken lichen]

And is that a .cginc file or an .hlsl file?

[celest ice]

yeah, it's .hlsl

.cginc looks the same

i can drag it in to the 'Source' field as .txt, but then I get the error. I guess it's a bug (or half finished feature) in 2020.2

[scarlet hull]

Why are you still on 2020.2a8 when 2020.3 lts is out ?

[celest ice]

sorry, i meant 2021

[scarlet hull]

That makes way more sense 😄

[celest ice]

is there no HDRP for 2021.1?

[turbid matrix]

?

it ships with it

@celest ice

[civic stump]

Thanks for your informations. On your question why i would do it: Its because of a custom - BEAUTIFUL - shader that i want to use to spice my graphics up. Sadly it doesnt work under URP and i dont have the time nor the knowledge to rewrite it into urp. So this might be the alternative i was searching.

[celest ice]

ah ok thanks olento, editing the manifest.json manually let me use it

[civic stump]

Maybe someone from the Unity staff can help out on this topic. I have no idea how to set a null-render pipeline asset 😄

[celest ice]

It appears Shadergraph custom functions are just bugged in 2021.2.0a8.. The includes get imported as ShaderInclude assets which is an internal Unity class 😦

[turbid matrix]

@celest ice you don't have to manually edit manifest, just open package manager and install HDRP

(or start with HDRP template for new project)

of course you can manually put it into manifest too if you really want 🙂

[celest ice]

hmm ok, it wasn't showing for me (just URP and Core RP were showing)

might be because my manifest had 12.0.0 in it

[turbid matrix]

you probably were looking it wrong place there, it's definitely listed

also you wouldn't install core yourself

it's always included through dependency

(unless you use these things from local files/github clone)

[scarlet hull]

https://docs.unity3d.com/ScriptReference/Rendering.GraphicsSettings-defaultRenderPipeline.html
GraphicsSettings.renderPipelineAsset = renderPipelineAsset;

There is an existing script in SRP.Core that allows to swat the assigned RP asset per scene : https://github.com/Unity-Technologies/Graphics/blob/master/com.unity.render-pipelines.core/Runtime/Utilities/SceneRenderPipeline.cs

[civic stump]

@scarlet hull doing it like this it will do the job but at runtime spit me out a null reference which is not very handly. Is this the only way to do it ?

[scarlet hull]

Hum, I think it should still work at runtime 🤔
But like mentioned before, switching RPs, in particular going back and forth with built-in is not officially supported.
We're working on supporting "Cross Pipeline", HDRP+URP combo, and the switch is done through the quality settings, where each quality level holds a renderpipeline asset

[civic stump]

Thats my simple code on an empty project where no Render asset is set as start condition and stored in variable A. Variable B is assigned in the inspector with the URP Asset

leads to some null references - but like i said it works:

[celest ice]

it's not just your logs showing the error?

(would make sense if GraphicsSettings.renderPipelineAsset is null)

[civic stump]

yeah. just figured that out. My bad :p

[turbid matrix]

lol

@civic stump so it works?

@celest ice this is a9, but it listed it on a8 too (there's no reason why it wouldn't)

[celest ice]

it's all good, i got it installed, thanks. It was 2021.1.0b11 that wasn't showing it

(which might be because my manifest had 12.0.0 in it, which doesn't exist in 2021.1)

[turbid matrix]

that's really weird because there's no reason why it wouldn't show it

I've tested almost every alpha / beta in last few years and have never seen that happen

not saying it's not possible, just haven't seen it happen

hmmm, I dunno what happens if you put higher number like that there

you'd still expect the unity registry to list the right one?

[celest ice]

my manifest just had "com.unity.render-pipelines.high-definition": "12.0.0", when I started 2021.1

(it fixed it when i changed it to 11.0.0)

[turbid matrix]

going backwards isn't fully supported so I guess that can happen

it can automatically upgrade that number

(from 11 -> 12) but I doubt it works the other way around

[celest ice]

actually I also had a custom copy of shadergraph 12.0.0, which could have confused things (because it probably requires RP 12.0.0)

all good, i switched back to 2021.2 and just modified the custom function node to allow .txt to work around the issue

[barren goblet]

hi everyone, unity how to profile a render pass GPU time, I write a SSAO, want to look into the GPU shader time.

[turbid matrix]

I've used nvidia nsight to measure things like that

no idea if some built-in tool on unity could give those figures (I've always assumed they would not give gpu side time properly)

@barren goblet

[barren goblet]

yea, I see profiler only track CPU.

[turbid matrix]

just saw this: https://github.com/Unity-Technologies/Graphics/pull/3913

"SSGI and RTGI completely replace all lightmap and Light Probe data. If you enable this override and the Volume affects the Camera, Light Probes, and the ambient probe, stop contributing to lighting for GameObjects."

did this change recently?

SSGI definitely worked on top of baked lightmap in past

(last time I tested was when the recent SSGI fixes weren't in yet)

[abstract matrix]

hey all, I have no clue where to put this, so ig it'll go here. I'm using unity 2020.3 LTS and URP, and whenever I open up either the project settings, or preferences window, I'm met with this loading bar that flickers on and off, making the editor impossible to use. I have multiple packages installed, and the only third party plugin I have is DOTween. I've already tried disabling auto refresh and other related settings. Am I doing something wrong? Has anyone come across a similar issue? I'd love to hear what yall have to say :)

EDIT: A full reimport of the project fixed it. Is this something I should create a bug report for?

EDIT 2: this only temporarily fixed it

[ember breach]

My last time it worked quite nice with baked lightmaps and light probes, maybe double calculation is the case? to not have both affecting models at runtime?

[mortal current]

Hey guys, I'm having some issue baking some spot lights that have mixed shadows

For some reason, only some of my lights seem to bake correctly, the rest just turn off and seem to have 'no lighting'

I thought maybe my texture map was too small or something and thus missing out some of the lighting

but I've tried it with a 4096 texture and still only a few seem to bake

Any idea what could cause this?

both of these lights are indentical

identical*

It would seem I'm getting baked lighting culling

whatever that is

[lone river]

is it here were I can find some help with the custom foward renderer data?

with the urp asset
