[summer glacier]

which is why HDRP has a CPU bottleneck problem, much of the problem lies in the C++ side of things, while they're making progress there it's fairly slow

(all of unity really) but in HDRP it shows even more because of everything else it offers.

I worked in unreal for a while, jumped ship to unity and will never look back no matter what new cool things they make. Only exception is if there's a massive change to workflow, and c# or it's equivelent along with a proper API and at least some documentation. That's just me though. 🙂

[inner parcel]

i have a gtx 1650 laptop which can runs my game at around ~200fps. performance is my main concern hence i dont just enable every setting and throw 4k textures at it. i do use few stuffs like SSAO / SSR / volumetric lights and few post process along with sub surface scattering materials.
my pc with a rtx 2070 gives me a huge 500-600 fps.
and yes my game has customizable graphics too. it doesnt make much difference to my pc, but my laptop can reach upto around even 300fps (with dynamic scaling factor as low as 60% and game running at 720p)

most of the hdrp games i've seen including mine has a gpu bottleneck and not cpu. in my case my cpu usage never goes beyond 10-15% whereas my gpu is burning at 100% all the time with vsync off in player

[summer glacier]

CPU usage doesn't say anything, very few games use many threads or cores, in unity

where GPU will always use all resources unless fps capped

[inner parcel]

by cpu usage i meant cpu usage across all cores 😄
and also the profiler ofc

[summer glacier]

if you profiled a build (Not editor) and CPU is taking longer than GPU, yeah you're probably CPU bottlenecked

although, when you enable graphic it will give a perf boost to your CPU. Problem is if graphic jobs are enabled, you can't profile GPU. and they only work in build.

[inner parcel]

i just know that my game isnt cpu bottlenecked : )
i've already done tonnes of research on it and its pretty clear in my case, so all good in there

[summer glacier]

you mean gpu?

[inner parcel]

isnt cpu bottlenecked

i've got the same results from a great lot of developers working on different projects in hdrp who have an optimized code base

[summer glacier]

I think i've read somewhere from a dev that HDRP sends the work of the next frame as well to the GPU, so the GPU always has something to do.

But yeah, there's also improvements to be made on the GPU for HDRP.

[dawn sorrel]

So you are saying I do have a safety net after all if deferred URP is borked in the beta.

[summer glacier]

The guy working on CPU optimizations plans to tackle that as well, but is focusing on CPU first

Wait, @inner parcel what FPS are you getting?

[inner parcel]

also if you go through the blog post for SRP batching, notice how they mention that boat attack and book of the dead has a gpu bottleneck on the device they're benchmarked it on

[summer glacier]

Yeah I remember that. Book of the dead uses a lot of GPU features, although I don't remember what boat attack is

[inner parcel]

~150-200 on my laptop depending on thermals, but when i start off its around 200
500-600 on my pc depending on the scene

in player, not editor

i get almost half of it in editor for my pc

[dawn sorrel]

Any of you doing open world?

Do I still need to use static batching or can SRP Batcher just go brrt.

[summer glacier]

I thought it was much lower. At that FPS, maybe there just isn't much to do for your CPU. Not a lot of objects etc.

[inner parcel]

i do have lots of objects in some areas in my scene : )
and yes more objects is generally a batching problem and the load is more on gpu when its drawing

[summer glacier]

I am, although it's more of a art scene than a game.
SRP batcher I believe should be your go to. I don't think you can use static batching when SRP is on. It just takes over static batching.

Although, if you have a lot of objects/meshes, combining them will still give you better results. Espcially compared to static/dynamic batching. Especially if you do cell based combining, so culling and lods still work.

There's an asset called mesh combine studio if you don't want to create it yourself, does a good job of just that.

[summer glacier]

Ideally, your game would be GPU bottlenecked. So you got that going for you. Always better than a CPU bottleneck.

[dawn sorrel]

Nah, I'm very lowtech so I combine my buildings myself.

I made this first building for the game and it's like 6 parts.

Base, railing, stairs, all windows and all doors.

I think that should be enough?

They are using different materials so combining them has no point.

[summer glacier]

Yeah should be alright.

[shrewd moon]

What made you jump ship?

I thought people usually jump the other way, when they eventually start wanting more engine control

[dawn sorrel]

Also correct me if I'm wrong, but don't modern engines use GPU driven rendering to avoid combining meshes by hand? Since the mesh data on the GPU will be in one continuous buffer they get non miserable editor experience and few drawcalls.

Idk the name, maybe it's called indirect rendering.

Basically whatever the Trials series has.

[summer glacier]

A bunch of different things, from both sides (unity/unreal). I don't like the node system. I despise unreal's C++ (+ it's API) and how verbose it is, I find their C++ documentation to be next to useless and you have to rely on engine source code findings for everything. The C++ workflow for me in general is lackluster compared to unity and C#. I like unity's gameobject system (not much interested in DOTS though), seriously like the editor customizability. Practically in love with C# and the API unity provides.
I like the general workflow of unity tools and menus. Drag and drop, sliders, options, etc.

It's a shame I have no access to unity c++ source code, on the other hand, it's more stable, with less changes in the C++ land compared to unreal. And due to the C#/C++ differential, i find indie games made in unity to be more stable/less crash prone compared to it's equivalent in unreal.

In general, personally, maybe to the opposite of others, I find it much less productive to work in unreal as single or small indie team, compared to unity.

Obviously, there's unity cons as well and they aren't few -- but in the end, I find unity to be a much better choice for me compared to UE. Especially now that we have HDRP.

[summer glacier]

Well, from my times with the built-in renderer, combining meshes based on a cell format gave me crazy performance gains.
What you're saying is probably indirect rendering, you have to use a particular API for that. I often use it to render anything that amounts to thousands or tens of thousands of meshes. Like grass, or a sand/dust simulation

[shrewd moon]

Makes sense to me
More power with an engine seems to almost always come with an usability cost, and vice versa

[inner parcel]

can agree. unreal is designed for bigger teams to work on. it becomes very hard for a developer to work alone on UE4 project unless its for prototyping

[near barn]

since there are to many messages between, can someone help me with that ? couldnt fix it yet

[dawn sorrel]

Haha, on Game Dev League Discord all the Unity devs meme and moan about Unreal being 100x better at everything all day.

[summer glacier]

No need to go to game dev discord, just check unity forums haha.

[dawn sorrel]

No, that Discord has been my home for 5 years 😋

[summer glacier]

I think they just believe the grass is greener on the other side, after all the difficulties they went through in game development. It'll all be better once they move to unreal. But it isn't, it's just a different color of paint. Old problems will go away, new problems will show up

[dawn sorrel]

I feel like with deferred rendering it could be theoretically possible to combine all the vertex buffers and do indirect rendering hidden from the user 🤔 You are already hiding shit in a fat fat GBuffer processed later already.

[summer glacier]

Man, wouldn't that be sweet. Maybe that'll be my dream for the night.

[dawn sorrel]

Or alternatively I could write a whole new pipeline with its own renderer components, skinning, culling, shadowcasting and lighting.

Sounds like a smol weekend project amirite 🤣

...I don't have good news about beta 9.

Why, why in the world is URP declaring a package for searching assets as a dependency 🥲

So much for modularity.

That very package has a dll conflicting with another package of theirs.

Turned it into a local package and fixed that by deleting a dll.

But...

It seems like they updated one part of URP but left the rest borked.

So URP doesn't work at all in beta 9.

So I either roll back to 8 or jump ship to HDRP 🥲

[dawn sorrel]

Annd everything is blinking on beta 8.

I guess I really have to use HDRP.

[inner parcel]

its just telling you what to do. create a new Universal renderer and slap the same settings as the old one and assign it in graphics and(or) quality settings

you need to also decide between forward/deferred in 21.2.x beta

[dawn sorrel]

Does anybody has idea how I should bake lightmaps for scene with vegetation in it?
I'm using HDRP btw

Should I make Vegetation use light probes or lightmaps?

[near barn]

i still need help

[inner parcel]

point light with ui?
i have close to 0 experience with 2d games but whats your canvas type?
screen space overlay will definitely not work

[near barn]

it's Screen Space Camera

[near barn]

also

if i set a camera

i have this red cross

[inner parcel]

hit play and see if the cross still persists

also turn off gizmos in game view

[near barn]

yes it does

[inner parcel]

the cross is there because you have a rect with negative width

[near barn]

oh it was gozmos

[inner parcel]

or height

[dawn sorrel]

Light probes.

[near barn]

after all that the light is still not visible

[dawn sorrel]

Oh, there are separate assets now?

[inner parcel]

because of the error youre ignoring by unity despite me mentioning it specifically for you

[near barn]

i set the camera

[inner parcel]

does it work with directional light?

[near barn]

nope

[inner parcel]

i havent tried lights with ui. maybe you need a lit shader for that

[near barn]

how do i set the lit shader ?

[inner parcel]

try world space camera once?

[near barn]

doesnt work too

this is my camera

[inner parcel]

you probably need a lit ui shader. head to #archived-shaders for more assistance on that.

[near barn]

alright

thanks for trying to help me

[dawn sorrel]

I am pretty sure the custom inspector for the pipeline asset is broke in beta 9 🤔

[near barn]

@inner parcelit works

i created this material

and given it to an image

[inner parcel]

glad to know 👍

[proud trench]

does anyone knows why the light only gets applied to the trees and grass but not the terrain? pls mention me when replying

[undone pecan]

Can anyone tell me why the directional Light doesnt work when you rotate it a minus rotation, so the light comes from the underneath in volumetric fog?

it just stops working when you go below 0.0.0

[proud trench]

you probably rotated that directional light looks like this

it does not face the ground

[undone pecan]

yeah, but im doing a space game, and i need the directional light to go from a negative value

any other way of doing it?

[proud trench]

only setting X rotation below 0

[undone pecan]

you mean the entire game? flip it so i dont have to go minus with the directional light? @proud trench

[proud trench]

the directional light

[undone pecan]

explain to me what you mean please.

[proud trench]

could you please give more detail what you want to implement(and yes im very noob at unity i have been using it like for a month atleast)

trying my best

[undone pecan]

the thing is that when im using volumetric fog, if i start pointing the directional light, it turns itself off. it doesnt want to light anything more if its poiting up.

[undone pecan]

anything lower then 0 i X turns the light off. in volumetric fog that is.

[proud trench]

i think "my experience" is way to short to try helping you. im sorry i tried to help you

just to let you know my brain is smaller than averge

[undone pecan]

you will never leearn anything if you dont ask 🙂 so keep it up.

ive been using unity since 2015, still dont know anything ;P

[proud trench]

actually everything on internet is arleady answered, so you need to search well )

[undone pecan]

im trying, but cant find anything.

[proud trench]

if you will try find hard you will still find a result, i remember a day just googling and took me 2 weeks to find the sulotion

[undone pecan]

usually sounds like my googling 🙂 thats why I ask and search. mostly search first and when i cant find anything, i ask here.

[proud trench]

i actually would recommend posting in r/unity3d in reddit there will always be people who will help you they literally saved my ass alot of times

[long wagon]

@undone pecan No reaction gifs, please.

[undone pecan]

roger roger, sorry

[inner parcel]

default hdrp settings

[inner parcel]

how about a local flipped volume with volumetric fog? not sure if that'll work

[sweet dock]

should i care with this error. it happen every time my project reload the render pipeline

[inner parcel]

clearly not

[inner parcel]

change the layer in decal projector to something else.
then whatever objects you want the decal to show at, in their renderer check for the rendering mask, and add it there

[inner parcel]

there were some talks about it long ago. i dont know if its there in 2021 or not, need to check once

.1 or .2?

[keen pivot]

right this is going to be a dumb question but i'm hoping it starts some cogs spinning from a comment or two on how i will go about solving this

i have a load of cars driving around a scene with headlights, it costs a load of performance to do this with a single spotlight at the front

if i turn off shadows for these lights, it helps a lot, but then they penetrate walls

is there some kind of standard trick people use to stop lights penerating an object but not cast real shadows?

[dawn sorrel]

So since I am on HDRP now and all... How do I.. learn exposure?

It seems like I am expected to know how compensation is different from exposure and stuff.

Do I like.. study photography or perhaps cinematography guides?

Also lol at the amount of decals in the sample scene just for a grunge.

About that.. I tried to google around and it seems to me AAA games use actual decals only for dynamic effects and instead use mesh decals for static environment?

[undone pecan]

lol, still the same problem. the light needs to come from below up. but i think ive solved it with an area light. but im not getting any volumetrics from it yet. working on it. but i have more pressing matters at hand.

[keen pivot]

is there any performance gain or loss from having Deferred Only lit shader mode over Both?

(in theory at least)

[inner parcel]

deferred has an initial overhead but theres considerably less performance cost for additional lights.
forward doesnt have that initial overhead, but performance cost increases for each light source you add.

which is better for you can only be told by your profiler. generally if you have many lights, and aren't targetting mobile devices, go for deferred.

[dawn sorrel]

Isn't forward+ better in most cases?

How does this math work? 🤔

[dawn sorrel]

Thanks.

The values I set up experimenting for over an hour are pretty close to that 🤔

[dawn sorrel]

Darn it, I broke UI rendering somehow.

Nvm, I set up the UI plane distance wrong.

Aaand 3d objects can stick through it 🤔

HDRP is weird.

[keen pivot]

thanks, not quite what i meant though, i'll elaborate. i am using deferred, i have many lights, i will not be using forward. i just wondered, if i enable 'both' in the HD asset, does it make any tangible difference either way in this case?

like, does hdrp do some magical stuff and create forward shaders in the background for some stuff

[inner parcel]

the "Both" option only makes a difference for builds in my experience. although in frame setting your camera chooses only one. I believe its for stripping shader variant

[flint sun]

Hi folks, i've got a bit of a problem with URP I'm hoping someone here can help me with...

I'm using a 3rd party plugin for a head mount display, it instantiates 2 cameras AT RUNTIME for the left and right eye perspectives

the cameras are instantiated with default settings

I want to script them to check the enable PostProcessing box

GameObject CamRight = GameObject.Find("Right Eye Camera");
UnityEngine.Rendering.Universal.UniversalAdditionalCameraData uacR = CamRight.GetComponent<Camera>().GetComponent<UnityEngine.Rendering.Universal.UniversalAdditionalCameraData>();
uacR.renderPostProcessing = true;

this works intermittently!

some times it works, other times unity will report that 'uacR' is a null object/reference

i tested this to be sure it's the game object, the cam component or the UniversalAdditionalCameraData part that's turning up null

it's UniversalAdditionalCameraData

so i look into UniversalAdditionalCameraData definition

it refers to "cameraStack" as the correct way to do this...

can any of u guys point me in the right direction to progress on this

(using Unity 2019 LTS and tried 21.1, same result)

[spring heath]

I've got a problem when using URP with custom post process effects in VR. The effects work fine in pancake mode. In VR, however, they generate a grey screen.

in pancake, the cameradepthtexture is OK

in VR, the CameraDepthTexture points to a default texture

So I think that the buffer "addresses" are different between VR and non-VR and I don't know what I have to change to make it render things to the correct places

I'm using the "Draw Fullscreen Feature" function from the URP examples

https://github.com/Unity-Technologies/UniversalRenderingExamples/wiki/Toon-Outline

Using 2021.2

[indigo summit]

say what happened with the Temporal Upsampling DSR? is it doesn't made it to 2021.2?

[spring heath]

seems I am having the same problem as this fellow https://forum.unity.com/threads/urp-scriptable-render-feature-blit-with-custom-shader-not-working-in-vr-mutliview.1092478/

[indigo summit]

oh nvm my previous question, i haven't update 2021.2 beta to latest

[gentle moss]

Sorry to pile questions before others are answered, but am I missing anything in the setup of executing a command buffer? I'm on 2019.4, using urp, and calling addCommandBuffer on a secondary (overlay) camera. The buffer works if I call it via Graphics drawProcedural, but does nothing when attached to the camera (it's not in frame debug or renderdoc either). Is there any check that could be preventing the commands from running? Am I missing some step?

[turbid matrix]

@spring heath URP's Blit is broken in VR since Unity 2020 or so. You have to use cmd.DrawMesh instead. Related issue ID: https://issuetracker.unity3d.com/issues/xr-sdk-urp-game-view-is-rendered-grey-for-left-eye-and-black-for-right-eye-when-using-single-pass-instanced-and-render-feature. They've marked it as "fix in review" but afaik their fix is to just add documentation example of DrawMesh approach

I have example of the DrawMesh here: https://github.com/0lento/URP_RendererFeature_SPI_Example but you can also see the official upcoming doc sample here: https://github.com/Unity-Technologies/Graphics/pull/5395 / https://github.com/Unity-Technologies/Graphics/blob/d72c3cbbfceee90ac81eb12609075da4dfdeffd2/com.unity.render-pipelines.universal/Documentation~/renderer-features/how-to-do-fullscreen-blitting-under-XR-SPI.md

@spring heath if you look into my repo's commits, you can see the meaningful diffs there, I intentionally implemented the old style blit example first, then did drawmesh upgrade there. Also worth noting that the extra copy pass removal on the last commit may or may not work for your effect since it uses global opaque texture for it (users can downscale opaque texture and it'll affect your end result too) so you can check how it was done prior to that commit too

[gentle moss]

Wait, are command buffers even usable on URP? It seems like the method to add one to a camera is no longer functional

[shrewd moon]

Is there some trick to using Render Textures as light cookies in HDRP? I can't assign them to the slot at all

Only found one source saying it doesn't work in build, like it's nothing special to get it working in editor

[chrome locust]

hello, just want to let you guys know, this PR has reached its final form.
First set of improvements of PrepareLightsForGPU is almost here:
https://github.com/Unity-Technologies/Graphics/pull/5294

if anybody wants to give it a go let me know 🙂 There will be a couple more pull requests for further improvements, but this one is the one that adds burst support, less stupid things in the light loop and overall big wins in perf.

[summer glacier]

Playing with the alpha, how do I get the volumetric clouds to render on the scene's camera? It seems to render only in the game view.

[calm turret]

hi, i know nothing abt render pipelines for the most part but im using hdrp and for some reason when i build, my exposure on my sky and fog volume gets reset

is there a reason this happens and if so how do i prevent this?

[dawn sorrel]

Yes. You get access to command buffers when writing your own custom Forward Renderer Features.

[analog rock]

Could there be an problem, if i create a new 3D Project without any RP selection, and than import the HDRP via the package manager?

[light spade]

I don't think so

[scarlet hull]

It should also open the HDRP wizard, at the top just click the "fix all" button to let it properly set up your project 🙂

[analog rock]

Thank you

[dawn sorrel]

I wanna tick RequestShadowMapRendering() on my OnDemand HDRP lights every 4th frame, how do you guys do it?

I kinda need the WillRenderShadowMap() method to know which registered light need to be ticked cause they are in the bounds but it's internal...

I guess I could copypaste the code for checking if the shadows are gonna be rendered and eat the double checks 🤔

[dawn sorrel]

And of course as soon as I use HDRP every HDRP user here dies 😢

[inner parcel]

why not attach a script to it?
do it once every 4 update frame on that script

[dawn sorrel]

@inner parcel well that will make it so first 16 lights in the world will register in the punctual atlas and the rest will just keep failing, no?

[dawn sorrel]

Well, I did manage to get nearest lights with culling but my code is still kinda broken. Pretty sure I forgot to evict out of range lights from the atlas so aggressive cleanup never gets them.

[agile bison]

im having a bit of trouble with render pipelines

is it possible to use the URP in a way that lets 3d lights affect 2d sprites intuitively? would it be really difficult to program/

this lighting stuff all just seems really complicated

actually #archived-shaders might be better to talk aboutt his after lunch so dw here

[heady elm]

can't tell if its a dumb question, but do scriptable renderer features from universal work in high def?

[dawn sorrel]

No.

Why does terrain on HDRP produce these awful normals?

Even with shadows turned off it looks like this.

[shrewd moon]

They don't look like vertex normals
Check if it's using a faulty normal map

[dawn sorrel]

Same thing without normal maps.

[summer glacier]

cloud layers rendering through objects. How would I fix this?

They should be way up obviously but, alas, they're not.

Any ideas?

[karmic sapphire]

im not sure how your clouds work but can you change thier priority in the material theyre assigned to

thats how i fixed this issue

@summer glacier

[summer glacier]

It's a post process override, 2021.1 HDRP feature

there's no priority for it I believe

[inner parcel]

is there a chance for this to land in 2021.2.0bX anytime soon? (or even 2021.2.1f1)
i just tested it out in a new project and im getting considerable improvements. would love to see it in my actual projects 😄

[chrome locust]

You know, it's not an API change. It's possible, but risky.

I do have to check with Seb. So far my testing I've fixed a lot of corner cases, but so far is getting stabilized

[inner parcel]

yeah thats what Im afraid of aswell. if it doesnt make it in 2021.2.0bX it wont be a thing before 2022.1 alpha right?

[chrome locust]

For 2022 it's absolutely gonna be there

I'd say it's gonna be in master soon. Soon as in 2 more weeks likely

[inner parcel]

being there in master is really a very good news

[chrome locust]

I expect corner case bugs.

I had issues with shuriken.

Wish we could just drop shuriken support fully

[inner parcel]

umm in that case i'll do a complete test in my actual project

[chrome locust]

Yes. I pushed last batch of fixes last night. So make sure you pull again

[inner parcel]

alright 👍

[chrome locust]

If you find issues please let me know :) I'd be absolutely delighted. I'll put your name on the PR for special thanks :) already had Oli help me out with his test level

[inner parcel]

thats not a problem 😄
as long as I see performance improvements and get the bugs sorted out and as long as you get the bugs fixed for your hardwork I see that as a mutual benefit

[chrome locust]

Absolutely. :) I want to make our users happy.

Expect corner case bugs. But I have time to fix them :) benefits outweighs the cost. CPU light processing falls into the stupidly slow category

It's basically a pile of code that had no design or ownership, and people just put their feature on top of more features. So it was in dire need of a rewrite

[inner parcel]

I always had issues with prepare light especially when i was using a laptop with integrated gpu (pretty old model) and normal use cases had a whopping 30+ ms just for preparing lights.
unfortunately i dont have access to that laptop anymore, but even in my current cpu i do see a reduced time from 2.5ms to 0.7-0.9ms
a great improvement. i'll stress it out more in my project and lets hope there's nothing major.

[dawn sorrel]

Ughh, why were lens flares added to HDRP only in 12, I don't wanna go to beta 😢

Imma see if I can backport it 👺

Nvm, it's embedded in SRP Core.

I'd rather use the one from somethingsomethingblu demo then.

[cinder root]

I can't find where the DLSS package is to download it

or otherwise how I activate it on Unity 2021.2.0b11.3437

I guess I'll try to find FSR...

[rotund mantle]

hope this is the right channel but I had a general question for some rendering experts - what would you do if you had a mesh that needed to share vertices, but not texture coordinates? for example, I have an icosahedron where the poles need 5 different texcoords on a single vertex

should I remove the constraint to share vertices and calculate my own normals? or is there another way around this?

[cinder root]

sorry I don't know your answer, but this may be the wrong channel. This one is meant to be about pipelines, so like HDRP or URP, etc

maybe you need 3d-art

[rotund mantle]

I don't think that'd be a good fit, this is more of a programming question

[cinder root]

oh like how it's rendering the object, not the way the object is made

[rotund mantle]

yeah

[cinder root]

well good luck with that. Sounds advanced

[rotund mantle]

thanks ¯_(ツ)_/¯

[inner parcel]

find it in hdrp asset, under dynamic resolution

[hidden karma]

Hi Unity people,
I'm looking for the best practice, canonical, non-stupid way to do something that's long bothered me in unity - I need to send data to a shader per render instance. I have a component that grabs the material of an object and tries to set some values- there are several ways to do that and I'm pretty sure I haven't fully understood the implications. There's renderobject.material and renderobject.sharedmaterial as well as 'GetSharedMaterials' and 'GetMaterials'.
Not knowing any other way to do it (although I think 'MaterialPropertyBlocks' may be the right way), I use SetFloat, SetMatrix and friends to set the values of these objects. In the editor, this works fine, in game nothing works.
I'm not absolutely certain what the difference between shared and non shared materials are - it seems obvious (one is shared and one is not) but it's not clear to me. It seems I'd want non-shared materials but that seems to work less than shared materials, although it gives memory leak warnings and doesn't work at all in game anyway.

It seems like a simple thing! Have a material, set uniform values in shader, render object but it's not. I'm aware of batching issues but I really don't know what the right way to do this is! Oh and I'm using URP.

[polar sorrel]

I don't know the answer to most of your questions, but I believe that a shared material is a reference to the material asset that exists at edit time, while the material is a reference to the material instance that exists at runtime. So if you make changes to the material (non-shared) you're affecting just that instance, while if you make changes on the shared material you're changing all objects that reference that material asset.

Not 100% sure, but that's my vague memory struggling with a related thing a while ago.

[hidden iron]

the warnings you're getting are probably because you are trying to edit the non-shared material when the game is not running, which causes Unity to serialize a whole new material into the scene, increasing its filesize. If you don't mind the extra draw calls in URP (material property blocks are not compatible with SRP batching afaik) you can use those: just create a material property block, call the SetFloat, SetMatrix, etc on it, then call Renderer.SetPropertyBlock to apply it to the object.

guys, in HDRP what are the benefits of using TAA? Is there something that wouldn't work without it? For example reprojection of volumetrics or something like that? Im really tired of it and wanting to switch over to SMAA, but I dont know if there will be any downsides

[wintry orchid]

I'm sure there's probably a forum post I can be pointed to or something else I've missed, but I've been looking a lot and can't quite find a satisfactory answer because the posts tend to be fairly old; could anyone explain to me simply the general use cases, advantages, and disadvantages of the URP and HDRP vs built-in? I've been working with built-in from the beginning, but URP and HDRP seem to both have some features I'd like to play with; at the same time, I'm worried about things I don't yet understand about them coming back to bite me. The documentation is better at explaining what these pipelines are, rather than what they aren't, if that makes sense.

Hi!
How could I get into rendering a ParticleSystem into a temporary render target via ScriptableRenderPass?

I've tried doing something like:

var renderer = MyParticleSystem.GetComponent<ParticleSystemRenderer>();
cmd.DrawRenderer(renderer, renderer.sharedMaterial);

But it does not draw any renderer under the shell (checked that via frame debugger).

[inner parcel]

if you have decided to venture into SRP
go for HDRP if you want to

• target high/mid end desktops and consoles
• get every feature out of the box

don't go for HDRP if you want to

• target low end devices (or devices without compute shader support)
• don't want too high visual fidelity for your game

go for URP if you want to

• target mobiles.
• target low end pc which don't support compute shader

don't go for urp if you don't want to

• rely on 3rd party or reinvent the wheel yourself

[ember breach]

As far as I noticed TAA in Unity is not in pipeline implemented like Battlefield does in newest Frostbite which without it breaks lighting etc. Here it is more of a post processing than in between of different passes.

[wintry orchid]

Wonderful, thanks for the concise explanation! To what extent do you mean relying on third party or reinventing the wheel?

[inner parcel]

Volumetric lighting (it's planned for urp too but no eta), SSR are some common examples

[wintry orchid]

Ahhh, I see. I was worried it would affect something more directly with my code, but that makes more sense; volumetric lighting is actually what caused me to start looking into the other pipelines anyway. I appreciate the explanation!

[dawn sorrel]

@inner parcel even my shitty budget laptop or my mom's office one support DirectX12 and compute tho, is it such a big thing on PC anymore?

[inner parcel]

even integrated cards such as intel hd 620 support compute shader. but they work very slowly

[dawn sorrel]

Is there a way to create terrain shader in HDRP?

[frozen fjord]

Hi, does anyone know how to get spot lights to work in URP after downgrading from HDRP? Clearing the Scriptable Build Pipeline cache in Preferences didn't work for me. I deleted my directional light and only have the spot light, still does not light the scene

[summer glacier]

Better volumetric clouds, better ambient occlusion, better volumetric lighting, and maybe improved performance for them but that i'm unsure about.
Although, if you disable/don't use TAA -- none of these will break. Everything will work as expected.

TAA in 2019 was bad, but since 2020.3 it's a really good implementation. Superior to other public engines that only use TAA as their antialiasing option. And you can tweak the settings as you like. Gets another improvement in 2021.2.

[dawn sorrel]

Well, if he material/shader support motion vector then TAA is pretty good in newer versions, it really eliminates specular shimmering and other artifacts much better than other AA options

[whole fossil]

For my experience the amount of ghosting and other artifacts is pretty unacceptable. The image quality is better tho, but it comes with a too much cost for me (try creating thin lines that are moving pretty fast - a rain for example). I think I'll stick with the msaa - maybe another LTS will make it more usable. Thanks for your opinion tho

[inner parcel]

TAA is hard to get right for your project. Once you do you'll love it. But yes it's still not as good as frostbite

[pastel notch]

Hi everyone. Are there any solutions for lit particles in HDRP?

[chrome locust]

I used to work in frostbite / dice. Frostbite's TAA was not that great imo. Windowing/clamping in frostbite was probably fancier. But say, TAA against grass or high detail background would break quite misserably

It would work great mostly because games would spend a lot of time tunning it a lot

It's the same in unity. Once you tune it just right for your project it will work great.

Particles and TAA in unity are a bit of a shit show. I put a checkbox recently to avoid ghosting / exclude some particles from TAA

If you guys have any questions about frostbite let me know :)

[inner parcel]

that sounds great! I had some issues with TAA and glowing edges but I didn't get the time to retune it again yet, I have an option in game to change AA to SMAA or FXAA on the fly and most of my testers just don't use TAA.

re frostbite the one at battlefield 5 was really good. almost no ghosting and light flickering and was absolutely great for still images

[iron flame]

I need TAA for rendering hair and eyebrows. I hate transparent. contact shadow doesn't work on transparent. so i use alpha clip with high mip. also TAA with hdrp12 is very good. better sharpening filter, blend factor adjustment(increases sharpness at the expense of jittering), still has problems with history sharpening filter. For me TAA is the only anti aliasing option. I will not allow the player to turn off TAA and I will encourage them to use TAAU. gtx1050 taau 720p => 1080p can get both very good graphics and 60 fps. There is almost no visual difference.

[inner parcel]

TAA is good indeed and compared to what it was in 2019 the things we now is much much better. And hdrp12 along with some tuning took care of all the flickering and ghosting problems for me. Even micro size vfx looks so good without flickering, but for some reason recently a tester reported this happening with TAA which didn't happen with smaa or fxaa. I haven't had the time to look at this yet, but I'll probably get back at this in few days once I slash few things from my to do list which also includes prepare lights for gpu branch on my main project

this is also using TAA and as you can see there's no ghosting at all with the hail storm done using vfx graph which means the TAA is doing a good job as promised (ignore the overall blurness as it's a screenshot from my mobile)

[dawn sorrel]

How is URP rn for mobile stuff? Android & iOS

Does it run good on the average phone without lots of tinkering?

[inner parcel]

URP is like the fastest option for mobile according to most of the people. Some had few performance drops with URP.
try to prototype it once to check how it fairs for you

[whole fossil]

the main issues I've had with TAA are related:

• canvas in world space parented to a moving object: it gets all the ghosting it can get 😄
• shader graph based decal that draws a some circles (think like sound visualization, or ripples). Then the line is to thin its simply invisible
• rain particles that are attached to the camera (same as the circle decal, makes those invisible unless using unlit with after post-process path)

I've tried fiddling with the settings, but I couldn't find reasonable settings. I've ended up with ghosting or just bad image quality

[inner parcel]

have you tried hdrp 12?

I'm not sure if 2021.1 has it, but 2021.2 does. there are some good improvements which I could definitely see but my problem with TAA existed there too

[whole fossil]

sadly no. Im bound to the lts version since I am using microsplat

it is really hard to cope with, but I kind of understand Jason's point of view

[inner parcel]

can you once show your TAA settings?

[cloud lantern]

in HDRP in a diffusion profile is it possible to set the world scale less than 0.001? (it always snaps back when i try)

[inner parcel]

wow that's so useful. I already have logic for few of those but it'll be super useful to have one directly from unity's team

[analog rock]

Does someone knows, how to set the emission intensity if a HDRP Lit shader via code? I found some forum topics and i have to multiply the color to set the intensity, but it wont work.
m_redlineRenderer1.material.SetColor("_EmissiveColor", m_redColor * 25f);

[inner parcel]

for emissive intensity if you use the keyword it will only update the inspector, not the actual material in game view.
even I faced the same problem once. I'll send you a solution for that in a bit once I get to my pc

[analog rock]

thank you

[inner parcel]

Set intensity like this first:

material.SetFloat("_EmissiveIntensity", 1f);

then update the material's intensity using this:

    public static void UpdateEmission(Material material)
    {
        const string kEmissiveColorLDR = "_EmissiveColorLDR";
        const string kEmissiveColor = "_EmissiveColor";
        const string kEmissiveIntensity = "_EmissiveIntensity";

        if (material.HasProperty(kEmissiveColorLDR) && material.HasProperty(kEmissiveIntensity) && material.HasProperty(kEmissiveColor))
        {
            Color emissiveColorLDR = material.GetColor(kEmissiveColorLDR);
            Color emissiveColorLDRLinear = new Color(Mathf.GammaToLinearSpace(emissiveColorLDR.r), Mathf.GammaToLinearSpace(emissiveColorLDR.g), Mathf.GammaToLinearSpace(emissiveColorLDR.b));
            material.SetColor(kEmissiveColor, emissiveColorLDRLinear * material.GetFloat(kEmissiveIntensity));
        }
    }

you can make your own extension or helper method if you want to do it in a go

just wanted to add that this code doesnt belong to me and i found it in forums when i experienced the same issue. hope this helps

[inland mica]

Anybody know why I'm having this issue with URP 2D Renderer?

[analog rock]

@inner parcel Thank you very much, it works 🙂

[hidden karma]

Hi folks.
I have a material property block and a component that, in the 'update' routine calls

_renderer.GetPropertyBlock(_propBlock);
//--set properties here--
_renderer.SetPropertyBlock(_propBlock);

But nothing happens at all. I'm not sure what I don't understand about this or am missing. Any clues?

The shader is a shadergraph, with bits of code as well. I'm using the mangled property IDs (e.g. _Vector_somehexnonsense) which return valid indices when using 'Shader.PropertyToID'.

ah, NVM, was a problem in my setup code: I was overwriting a variable that I needed.

[weak shuttle]

hey, i have a problem

i

accidentally installed two different samples when installing pollybrush

and i don´t know how to remove the wrong one

[inland mica]

Why is this only happening on WebGL builds after adding Universal Render Pipeline?

Works fine on PC build and in the editor

[inland mica]

Also building to android, the UI shows but none of the prefabs or textures. I'm pretty sure this is down to URP also.

Everything works perfect on PC

Universal Render Pipeline not so Universal

[wind fox]

I'm experiencing some weird behaviour with skyboxes and OpenGLES3 on Android:

• Wrote a shader in shadergraph for my Skybox
• Set it as the scene skybox through the Lighting settings
• Shows into the editor
• Shows into the build if I use Vulkan
• Attempt to switch to OpenGLES3
• Skybox doesn't show, instead I see the default dark blue background

[inland mica]

I'm guessing this isn't a support discord

[wind fox]

Replying to myself: apparently, OpenGLES3 doesn't know how to handle Shadergraphs used as Skybox

[wind fox]

Not over yet: A skybox made with Shader Graph will only render in an OpenGLES3 build for VR IF AND ONLY IF the stereo rendering mode is set to Multi-pass; attempting to set it to Multiview will break the skybox.

any ideas on how to go about optimizing this?

UpdateRendererBoundingVolumes in particular

[dawn sorrel]

@iron flame sir

how u had that soft shadow ?

[iron flame]

mixed lighting, distance shadow mask mode. This is my favorite mode on mobile. Currently on sony xperia xz1 (sd 835) 720p, TAA, object motion blur, real time soft shadow 2048 and mipfog 60 fps.

[summer glacier]

Object motion blur? Isn't that still in the works, not released yet?

[iron flame]

I added motion vector to camera motion blur shader :D

[summer glacier]

Is this related to particles?

[sinful locust]

no related to the number of objects in scene I think.

[summer glacier]

Looks like it

https://forum.unity.com/threads/update-renderer-bounding-volumes-higher-time-ms.709322/

Never faced that issue so can't help unfortunately

[sinful locust]

https://cdn.discordapp.com/attachments/804225222769246218/887212980012474368/unknown.png

I have optimized everything else where I can get over 3x this number of objects in scene in a streaming fashion.. but render is being lame every x frames 😉

only happens when my ship moves fast, which results in my object pooling system to despawn and respawn objects in the ever moving sphere around my ship.

[summer glacier]

From my reading it has to do with scene hierarchy, https://www.gamedeveloper.com/programming/unity-your-scene-hierarchy-is-robbing-you-performance

but maybe the cause can be other things as well

[sinful locust]

ya its not hierarchy in my case

my pooled render objects are all in one flat scene, are not parented and dont move.

[summer glacier]

is your testing in build or editor?

[sinful locust]

the impact greatly reduced in full build, but its still there

[summer glacier]

mono build? Did you try il2cpp build?

[sinful locust]

il2cpp master build. Again, its cut by 50% or so but I see same frame spiking

is there a way to get deeper data on what is happening in the render processes?

the spikes with the orange are more editor/profiling related, but the real tall green ones are all render.

[summer glacier]

Deep profiler is the only thing that can give you more profiling data. I believe it's for your scripts, but it might give you an idea of a call that has something to do with this spike

[sinful locust]

thanks

[summer glacier]

How does light culling work in HDRP? Are lights not in view culled/not rendered?

Or is there still a use for a script that disables lights if it's (x) distance away from player.

[inner parcel]

lights out of the frustum are culled.
you can test that out by putting 1000+ lights at one spot and just moving your camera towards and away from it. and then by adding an obstacle between you and the point while you're looking towards the point

[summer glacier]

Nice. Yeah I saw some stuff about checking light visibility in the profiler so I thought it's likely culled.

[sick vector]

how would i go about fixing the transparency sorting?

these are set to the same priority as the platform yet are showing over it

[dawn sorrel]

First of all, lights are frustum culled. Then there is a max light on screen limit you can set in the HDRP asset per light type. Then if you click the cog on the emission section of a light component, you will see a light fade distance field you can set to have the light automatically fade out at a certain distance. It's set to something crazy like 10 kilometers by default. The shadow casting section also has a shadow fade distance setting if you press the cog to expand the options.

Also the HDRP asset has a setting for max shadows on screen and for max shadow requests per frame.

[turbid matrix]

@sick vector which renderer?

[sick vector]

Lightweight render pipline, but just by creating a new render profile i can edit the sorting axis and whatnot

[turbid matrix]

asking because in built-in renderer you could have used this https://github.com/candycat1992/OIT_Lab

and yes, transparency sorting is quite broken in URP, I do wonder why Unity doesn't do something like OIT for it

[sick vector]

i mean the fact that there isn't more than

1 light being able to cast shadows is even more of a

[turbid matrix]

but like, in your case, you want the ghost to always render on top of everything?

[sick vector]

no i don't

it's behind the platform and is supposed to look that way

[turbid matrix]

and you can't make the platform opaque?

[sick vector]

naw they use transparency for the fade out effect

[turbid matrix]

one could do some dithering alpha cut setup but I guess it doesn't really look as nice

[sick vector]

I find myself questioning a lot of choices when it comes to the render pipeline features, mostly that there seems to be no, middle ground one
only low end or high end

all I wanted was to make clouds cast softer shadows but no

[turbid matrix]

but yeah, OIT would solve your issue, I'm just not aware of any solution for it on URP

[eternal laurel]

I just looked at the code turning this into a URP version might be a fun side project

[drifting vault]

Nice. Would be good to have that on Asset Store =D

[iron flame]

maybe 🙂
I am also working on contact shadow. But I'm having problems with Matrices. I had similar problems while writing SSR.

[ember breach]

Is there a way to leave a RT in buffer for next frame? would like to modify it in one frame and then modify again in another but still have old data

[turbid matrix]

@ember breach it doesn't work like that by default? just don't release it yourself, also if you use GetTemporary it may destroy it for you.

meaning, you probably want to allocate the RT yourself

[ember breach]

Right now for the start I am using the example Unity provides to do your own Renderer Feature, so it manages it for me, but at the start I can see that the RT is empty, so if it should be by default I should then look at how to make RF myself.

[turbid matrix]

you sure you don't release it yourself anywhere?

pretty sure many effects that require some kind of history buffer do the swapping between two RTs

[ember breach]

After render feature is done I don't do anything else with the RT, and next frame I just get empty RT at the start, but will look deeper into it after work today

[turbid matrix]

not sure if URP has such effects but HDRP TAA has even dedicated history buffer handling

[ember breach]

yeah, not sure if it does, will dig more, caus would like to eliminate checkerbox recostruction and just every other frame trace the other pixel instead.

[turbid matrix]

hmmm, they even have this https://docs.unity3d.com/Packages/com.unity.render-pipelines.core@12.0/api/UnityEngine.Rendering.BufferedRTHandleSystem.html (in case you have to have multiple RT's, it has functions that Swap between etc)

[ember breach]

Thanks will look into that

I wonder how much new RT changes in URP will change the pipeline as they trying to port more HDRP stuff into URP, worried a lot might break

[turbid matrix]

trying to make HDRP 2? 😄

but yeah I get it, seems like there's like half a dozen people even on this channel going that route

[ember breach]

I do not feel like HDRP is fusable for gaming, its good for cinematic but performance is not there

They also told us that URP will be more customizable and open for your interpretation, HDRP on the other hand is fully made for high level graphical features

I just hope Mesh Shading etc. will drop in URP aswell, would love even more performance 😂

[turbid matrix]

virtual texturing in URP when...

that even feels like it's not super complicated to add but they just haven't done it because their focus is elsewhere

what's funny is that Unity actually did URP implementation for VT's first until they did 180 and only implemented HDRP for the VT previews

those urp dev branches are long gone too since they were on the old SRP repo

[ember breach]

yeah, I am not sure what they are targeting tbh, I see 100 pushes to HDRP and like 5 meaningful pushes to URP, sad to see

[sinful locust]

I haven't had any performance problems with HDRP

I really think it depends on how you use it and tweak it.

[turbid matrix]

you can dial down HDRP to make it perform better, it's "fine" on desktop use altho URP seems to always outperform it regardless

[sinful locust]

I mean if u have an empty scene with a few objects sure URP is going to have double the fps. But when u start filling up the scene, tweaking/optimizing options I dont see a huge difference.

[turbid matrix]

my issue with HDRP isn't the desktop experience (altho I'd love to see it scale further down there as well) but it barely running in VR with higher resolutions

[sinful locust]

even with hdrp 12?

[turbid matrix]

yes

HDRP doesn't really do well with high resolutions

[sinful locust]

Hmm. My test scene has 30k asteroids (full gameobjects mind u) in it and I am getting 200fps at 4k

[turbid matrix]

I could like run HDRP in VR with reduced resolution and use TAAU to upscale it and get decent visuals but it's still slower than URP in VR

that being said, there's been some nice HDRP perf improvements in recent versions.. it's just not enough for VR

[sinful locust]

fair enough. My main reason for going with HDRP is just the maturity level vs URP.

[turbid matrix]

I mainly see HDRP being more featured, both still have growing pains

[inner parcel]

30k asteroids 200fps and 4k? seems like an impossible task to achieve
which hdrp version (or unity version)? whats your pc specs? which shader for asteroid? which features did you strip from hdrp (or which ones do you use)? whats the game view stats (tris, verts and batches)?

im normally highly gpu bound. crossing 1080p or sometimes even 1440p severely hurts my performance for my use case (i get 400-500fps at 1080p and not more than 200-300fps on 1440p on my pc but its extremely optimized and i use very rare less hdrp inbuilt features)

[sinful locust]

depends on loding aggressiveness. I got over 2x that with icospheres.

2880ti 9900k

and technically I was running in 3440p not quite 4k

[inner parcel]

yes but im just interested in what was there on that specific frame in which you were able to achieve 200 fps with 30k asteroids in scene

30k is too much man. i cant imagine even batching helping you achieve 200fps on 3440p with a 2080ti

how many asteroids were actually visible?

just for a rough picture

[sinful locust]

I wrote my own system for managing this

these objects are pooled and streamed and do not use unity update methods at all

I also have my own spawning/sectoring system

[inner parcel]

pooling is a cpu and memory optimization. im concerned more about the gpu part in here

difference between 1080p and 4k is lot less on cpu but exponentially higher on a gpu

[sinful locust]

it totally depends on the number of tris in the scene. As I said with icospheres it was quite a bit more. So if I turn LODing very aggressive I can get insane results

[inner parcel]

yes thats the basic gpu optimization technique xD
just forget about that. im just interested in your stats basically. what you had on your camera view, and what your game view stats window/performance showed at that point.
you said you achieved 200fps with 30k asteroids. i just am interested in that, with all your specific condiguration of your object pooling, LOD, your 3440p res, etc

[sinful locust]

I have LODs set pretty high here and I don't have HDRP tweaked for optimization in this scene, its also in editor

36k obj

[inner parcel]

that really seems insane. do you use srp batcher?

[sinful locust]

no

I am not using anything but unity 2021.2b and my own code

[inner parcel]

does that negatively impact your project?

[sinful locust]

does what?

[inner parcel]

srp batching

[sinful locust]

haven't tried it for this. Right now I am just working on optimizing my streaming and pooling system. I have not yet attempted to optimize render or other aspects.

[inner parcel]

im really interested because almost a year ago i created a vfx with some vertex animations (little above 10M tris) and i was really bottlenecked with hdrp. so i was little bit interested in your system if you do anything differently

rendering is the pretty much hard bottleneck for me with hdrp. cpu is well fine in my case

[sinful locust]

Not that comes to mind. My system just takes prefabs splits them into two objects, one for physics one for render/sound. Pools them, then spawns/despawns as you move through "Sectors" of space. I can handle about 100k icosphere at 60+fps in full build, streaming in/out 5k objects per second.

and that is without batching or any other optimizations, using default "medium" hdrp profile.

[inner parcel]

batching is still a cpu optimization. although lod is pretty good for gpu. anyway nice work.. you still have lots of room to squeeze some juice from

[sinful locust]

i got a video one second

https://www.youtube.com/watch?v=ijXsjMlWkbw

and yes those are actual full unity gameobjects, not just render quads heh

[inner parcel]

good stuff keep it up

is there any hdrp stuff you have a hard need for? just curious

[sinful locust]

well there was when I started, but URP is catching up. Mainly the decal system at this point. I also thought I needed the camera relative rendering, but ended up creating our own system using jobs which is fine.

I also plan to use volumes for unique skybox areas but other than that nothing hard.

I believe there is also some compute buffer and instancing functionality coming to HDRP in the next release that looks interesting.

actually that was shader graph not HDRP it seems

[inner parcel]

just a suggestion, nothing to think too much on. you can give urp a time if you have some spare time.
most features you've mentioned can be done in urp. camera relative rendering you already have. you can use good old box colliders to trigger skyboxes using trigger enter.
and urp devices supporting compute shader are fully supported by vfx graph. instancing is for vfx graph not shader graph

at current state both hdrp and urp suffer when it comes to instantiating a vfx at runtime

with vfx instantiation i dont think theres anything left for me which would make me even think about using shurikens anymore

[sinful locust]

ya I am not in a hurry, at this point I just dont see any reason to jump ship to URP at this time.

[inner parcel]

true its not worth jumping ship and just end up juggling between the two as features add up. just one thing to think about is that urp is basically a free performance boost if you dont use anything in hdrp which is missing from urp. i spent almost 2 months to convert my hdrp project to urp (when deferred was released for urp) with some visual sacrifices for performance gains. i almost got 2x performance boost in urp but i just scraped it because we still needed few things which were missing in urp out of the box

[sinful locust]

I'll likely wait until the artists get a world to play with and see what features they end up using and decide based on that

we still have a lot of work to do before we need to worry about the particulars of the render lol 🙂

[summer glacier]

I feel like urp has a long road to get close to HDRP.
Some of the important things it lacks that exist in HDRP: TAA, SSR, dynamic res upsampling (FSR/DLSS/TAAU), Volumetric clouds, Volumetric lighting (big one), better post processing, better SSAO, some HDRP shader features, camera relative rendering, better fog, better shadows, etc.

And the worst part is URP's development is very slow, where HDRP is fast. Just look at github and update history. Who knows what feature HDRP will have in the future that URP will never get, or it'll take years.

HDRP does a lot of things compute, urp does it on the CPU.

the performance difference is there. Although If you do high-end 3d graphics from my testing HDRP scales better actually. And latest HDRP versions have big performance improvements.

why is the SRP batcher not batching my chunks

im on unity 2021.1.19f1 and urp

the chunks are generated procedurally during runtime

my batch counts and setpass calls are the same no matter what

each chunk uses the exact same material

[turbid matrix]

most of the items listed are available for URP from 3rd parties but then you get back to the "built-in renderer" experience 😄 only FSR/DLSS side is something that doesn't have offerings atm

also HDRP SSR and SSAO are tricky as those implementations don't necessarily suit everyone's projects

GTAO is nice when it works but it can have nasty artifacts where some other AO tech might work better for you

and HDRP SSR... well... the rough surface implementation isn't great, if you use the more physically correct option there, you'll get tons of ghosting, making it impossible to use in any game

I feel like that last thing is mainly something that better denoising could fix

main biggest pro of HDRP IMHO is that it's so featured out of the box, can get most bells and whistles on stock HDRP where with URP and built-in you have to do more stuff yourself (or buy from 3rd parties)

[warm crescent]

hello people. We have a fairly advanced project and we are thinking about changing from legacy render pipeline to URP....
For the moment I see most of all of the renderers we are using will have to be replaced but I didn't see anything regarding the code...
I mean.... I interact ocasionally with some material's shaders properties like color.. alpha etc... Will we have to replace this code too or the way of interacting with the shaders it's the same?

so... my question is... by changing from legacy RP to URP... do we need to change how the code interacts with shaders? or we just have to change the shaders to be compatible with URP and the code will still work ?

By the way. The main reason we want to change from legacy to URP is because of the shadow jittering problem that seems to be present in legacy RP and Unity won't fix.

[inner parcel]

you're on the wrong track of you're changing legacy to srp just for shadows. for bigger projects you need to do more research and before just jumping ship it's always advisable to create some prototypes just for urp and hdrp so that you see what's the difference without breaking your head to fix your broken project even before you start seeing the capabilities

[turbid matrix]

@warm crescent no idea on the jittering but are you using NGSS? it makes built-in shadows all better

URP shadow filtering is way worse in comparison

[warm crescent]

whats NGSS ?

😅

[turbid matrix]

it's a paid asset to do better shadows on built-in

not horribly expensive

https://assetstore.unity.com/packages/vfx/shaders/next-gen-soft-shadows-137380

[warm crescent]

thank you im gonna take a look

[warm crescent]

yes actually we were going to make a branch to try it we are not jumping blindly 😅

[sick vector]

I am using HDRP and well in the attatched image you can see that the mip mapping is...a bit noticable, where are the settings related to it?

ah, figured it out it was on the texture itself

[inner parcel]

what I actually meant was to test things out in a new project. it's still a headache to convert everything in your project to see the actual benefits. but yeah feel free to experiment with whatever suits your preference

[warm crescent]

thanks @inner parcel

[keen pivot]

i has a confuse. in thought in the frame debug you want as little draw calls as possible

but the docs page here suggests you want a higher number

https://learn.unity.com/tutorial/working-with-the-srp-batcher#5ff76df1edbc2a6d02b058ea

example from my project

whats the goal here supposed to be, what would a better list look like? what would a worse one look like?

i'll post a portion of that docs page, dont expect anyone to go off and read that:

This column shows you how many Draw Calls have been batched. The higher the number,
the more efficient it is. If you have a lower number, it could be a sign that you have too
many Shader variants, and that your SRP is not as optimized or taking advantage of the SRP
batch processing. In the test case Frame Debugger window of (Figure 07), the Draw Call
number of the Render Camera is lower, when compared with the more optimized test case
Frame Debugger window of (Figure 08), where more Draw Calls are utilized.

copy/paste on that page was way harder than it needed to be

[turbid matrix]

I really wonder about this "mesh data optimization"

it's become a major PITA on 2021 cycle especially

build times take forever if it's enabled (and it's enabled by default on some templates too)

would always need to check it's disabled when testing other things

mentioning it here as I don't think it's really an issue with on built-in renderer

[summer glacier]

Use NGSS, don't use URP for shadows. It has worse shadows than built-in and no NGSS support. If you want good shadows built-in, use HDRP. Although if you're building a mobile game, HDRP wouldn't be an option.

https://issuetracker.unity3d.com/issues/shadow-precision-issues-far-away-from-origin-needs-reverse-fp-depth

look at the Resolution note lol

It wouldn't be an issue if URP's development wasn't moving at snail pace.

[turbid matrix]

I don't really see URP dev pace being any slower than about anything that happens inside Unity, pretty much all their systems develop in really slow pace. HDRP gets some bleeding edge stuff that remains experimental faster but if you just look at the core stuff on HDRP, it's not advancing any faster IMHO

I'd want to note also that URP 12 got huge update on tons of things so it's not like there's nothing going on there... of course URP12's new features have been in development for ages but can't still neglect that they finally got all that stuff out

[warm crescent]

but this issue seems not to be the same... this issue is about large terrains no? my problem is more like this one:

https://forum.unity.com/threads/directional-light-shadows-flickering-issue.672094/#post-7499960

btw my post is the last one, the building game one

[turbid matrix]

@warm crescent first video on the thread you linked is related to large game world

it's directly coming from floating point accuracy you get when you go further from world origin

[warm crescent]

yes, it doesn't seem to be the exact same issue right?

[turbid matrix]

if you have jittering shadows like there, any amount of fancy shadow filtering will not fix it

also you will have same issue on URP

[warm crescent]

no but my environment is not a large one

is not my case

[turbid matrix]

but is it near the world origin?

[warm crescent]

you mean the video of the small scenne with 1 human model and 1 sphere?

[turbid matrix]

yes

[warm crescent]

if its near the world origin.... im not sure what that means im sorry 😅

my example is this

https://youtu.be/IebHUDXiJA8

[turbid matrix]

by being far from origin, I mean that if you have like absolute tranform position value and it's a big number, it's far from world origin (0,0,0)

[warm crescent]

mmm not really, the mapTile is close to world origin... grows 128 tiles of 3.2 in x and z

and its in y =0

and the camera doesnt move more than.... maybe 200

from any point of this map

[turbid matrix]

200m isn't much

[warm crescent]

thats not a big number no?

[turbid matrix]

no

[warm crescent]

i think is not exactly the same problem

ive been told to switch to STABLE FIT shadows ode

mode

but then look what it happens

its like just the closest to the camera are drawing its shadow

i think its another issue

anyway i contacted with the NGSS guys, shown them my case

[summer glacier]

Come on, point light shadows only now in 2021.1, reflection probe blending only coming now in 2021.2, box projection, deferred renderer not even released yet, coming in 2021.2, motion vectors as well, light layers, no TAA, shadows worse than built-in, no shadow cascade blending, no volumetric anything, no camera relative rendering, light cookies only now coming in 2021.2, no auto exposure, no screen space reflections, and more.

The fact all that stuff is only now making it in 2021.2, after how many years.. has to be snail pace, cause if it isn't, I don't know what is.

Many features that took a very long time to be released were expected to be of higher quality than built-in, but they're about the same, sometimes lower.

decals are only coming now in 2021.2.

I use HDRP exactly for this reason, I don't want to use assets anymore, so much pain or bad quality down the road. I want to limit them to things I trust.

Not to say I don't use any, I do, but i don't want to use so many, and many of them for features I deem critical and should already be provided by the engine.

Wasn't URP declared production ready before 2020.2? Cause if it was..

that means it was also missing SSAO, and shadowmask. Probably a bunch of other things I don't remember.

And now deferred is coming, so most assets for URP will break and will need to be updated.

HDRP had all or most of these years ago

[turbid matrix]

production ready != fully featured

also pretty sure LWRP was already "released" while HDRP took longer to get official release

[summer glacier]

We aren't really even close to fully featured, we need something though. Unity is known for being barebones, but URP/LWRP was bare-bare bones.

[turbid matrix]

all in all, URP is still universal target where HDRP only supports few targets, that has to limit things too

[summer glacier]

I mean, ignore 2021.2 -- and check previous updates. Very little features. Snail pace.

[turbid matrix]

that being said, pretty sure most of the users would have just wanted one renderer

[warm crescent]

well the issue trackers are full of annoyed people thats for sure 😅

and the forums

[turbid matrix]

also I'm not going to ignore 2021.2 as that's where URP finally got tons of things they've been cooking for year+

[summer glacier]

HDRP supports the ones that I deem important, I don't care about switch or mobile, don't even want to think of getting it to run at an acceptable FPS in those platforms.

[turbid matrix]

it's like saying ignore what HDRP did for the past 2 years and look how raw it is

[warm crescent]

we are developing for mobile 😦

[summer glacier]

The point is that before 2021.2, which packed a ton of critical long-overdue features, they were slow, and they still are. If history is anything to go by, they'll go back to slow development.

[turbid matrix]

I do get the frustration but if you've been using Unity for longer, you know they like to take their time to get about anything done

[summer glacier]

Past 2 years is not the same as one single update.

I understand that, but HDRP has been going at a faster rate since the start.

[turbid matrix]

having used HDRP from first days... I'd disgree 😄

[summer glacier]

Just check changelog, or roadmap. Look at the features added per major unity update.
compare that to urp. It's not even remotely close

and the fact unity broke render pipelines into 3, means using assets is even more of a pain now then before.

For example, the best clouds asset in terms of quality, Expanse, only supports HDRP.

[turbid matrix]

this

[summer glacier]

Because urp is too much pain to support alongside hdrp

I agree, but we can't undo the past :/

Even though URP is the one that really needs it, since HDRP is getting good volumetric clouds in 2021.2

[turbid matrix]

all in all... which renderer you pick today totally depends on your project and it's requirements

[summer glacier]

No disagreements from me there 😄

To be honest, i do agree that sticking to one RP would've been better.
Sometimes I look at urp and say.. that's nice.
then I look at HDRP and say.. that's nice.
Then I look at built-in and say... that's nice.

Then I have to choose one 🙂

[warm crescent]

any idea about my problem? I tried setting the shadows to STABLE FIT but i got this problem:
Also I tried to maximize the shadow distance until 1000 but no changes... out of ideas 😦

[summer glacier]

Nope, sorry :-
you're in the built-in land, mobile to boot

NGSS might help you, although, i'm not sure if it's good for mobile..

[warm crescent]

i've read is compatible with metal so i guess

[shrewd moon]

From what I understand URP is designed to have all its features as universally compatible as possible, which is one reason why they take longer to implement
If that doesn't matter to you, that's fine, but it's still a reasonable factor to note when judging it

[summer glacier]

I've heard that before and it's a fair point, but I doubt i can judge it fairly if i have no interest in the platforms holding it down

[turbid matrix]

also if you need VR, HDRP is not a good pick

if I only did desktop only, I wouldn't even consider URP

[summer glacier]

Although one benefit is that they probably are very performance sensitive

[turbid matrix]

meanwhile... now it's revealed, we are all just bunch of numbers to Unity

[summer glacier]

Yeah, I've no experience in VR but I'd say that's true based on what I read.

[summer glacier]

and here I thought i was building working relationships by reporting bugs

😄

Now that I think about it, it's funny to think off it the following way.

Not in the literal sense, URP VS HDRP can be considered roughly to be two different engines.
Just like how there's Unity vs Unreal.
There will be URP vs HDRP. More and more as people stop using built-in.

Unity, all about 'unity'.

[shrewd moon]

It does feel like almost a different engine with its own quirks and tricks
But as with engines in general, the best choice is the one that fits the project's needs

[warm crescent]

what i truly wonder is if all this issues that are marked as obsolete in built-in render pipeline are really fixed in URP

[summer glacier]

Good question, I couldn't really say since I don't use urp much

[dawn sorrel]

SRP developers should have learned about ifs, I heard those really help having a single multiplatform pipeline 😎

[chrome locust]

yall not a number to me ❤️ users are very important for me at the least 🙂

[summer glacier]

We appreciate you too 😄
I'm Ovi by the way haha

[chrome locust]

ah! excellent ovi 🙂

thanks for that test scene you sent me, I caugt some bugs on that PR 🙂 its on its final stages. PrepareLightsForGPU about to get a nice perf improvement

will let you guys know when its ready

[warm crescent]

may I ask what are you working on?

sorry im new around this room, nice to meet you

[summer glacier]

I actually tried to do another test for il2cpp a few days after, but the latest branch kept giving me kernal and some code related errors. It might have something to do with the unity version I was using, which was the latest 2022.1 alpha at the time

[loud leaf]

https://github.com/Unity-Technologies/Graphics/pull/5294

[warm crescent]

I seeee. impressive 👏

[loud leaf]

Have you thought about creating a reusable package for the boilerplate entity collection/create/removeatswapback code? I'm also burstifying some stuff and keep running into the same

[chrome locust]

@loud leaf well as I understand the entity package can do that. The tricky part though is SoA is not something you can easily abstract. Or even use generics.

The best I did was adding the concept of Resize in Core as an extension of NativeArray.

the entity package is also a bit heavy for that matter.

[arctic parrot]

I dont know if anyone can help me but i have this issue that i am trying to solve.
Basically i have 2 SpriteRenderer ontop of eachother with different Mask interaction. One is set to visible outside mask and the other one to visible inside mask. When i drag my objects over the mask one gets rendered and the other one doesnt like the mask interation have been set. The probleme is that i have the Sprite Mask on a different Rendering Layer Mask so it doesnt interact with these SpriteRenderers but it does anyways.

Nvm fixed it by adding Sorting Group Component to the mask

[verbal apex]

I'm having a really weird bug when upgrading from the standard pipeline to the URP. We upgraded to the URP and now all of our lights are behaving as if they are set in gamma color space, when the project is in linear color space.

Is this some known issue? I've swapped back to gamma, looks like crap (too dark), swapped back to linear, literally no difference.

We were in linear space previously, why is it so dark now? 😦

Yeah, I've got a brand new URP project made and the lights with the same settings are baking down entirely different between the two projects despite being in the same color space. Is there some project setting that I'm missing? They both should be using the same render pipleline and settings.

[verbal apex]

Literally copied and pasted the pipeline assets. Two URP projects using the same player and graphics settings using identical pipeline assets are rendering entirely differently.... I'm at a complete loss....

[lean kestrel]

I was trying to make a sprite glow and I installed the universal render pipeline, and after a while I got this error and I have no idea what is means:

"[Worker0] Shader error in 'Hidden/Universal Render Pipeline/Blit': Couldn't open include file 'Packages/com.unity.render-pipelines.universal/Shaders/Utils/Fullscreen.hlsl'. at line 20"

oh and some of my sprites appear as purple squares

[lean kestrel]

Now I removed the universal rp and every prefab that I have appears as a purple square in my asset folder. Any way to fix it?

[inner parcel]

if you dont have a backup of your previous project before doing all the stunts then you're screwed.
its actually pink not purple. it happens when theres a material missing in the renderer, or some incompatible shader. i assume its shader in your case.
standard shader to urp shader the shader converter can do it for you. but theres no universal to built in shader converter

[lean kestrel]

it is only in the project window

it is ok while playing

[inner parcel]

make a build and check it in there. pretty sure that'll have pink boxes too

[lean kestrel]

and what did you tell me to do exactly because I didn't really understand. I have never used shaders and rps before

[verbal apex]

Ok I think this has to do with lighting falloff changing in URP; that would make sense as to why lights in standard look good but when upgraded to URP, they look dark.

[verbal apex]

Yep, progressive lightmapper's light falloff is different from the previous lightmapper. Oddly this happened at the same time we upgraded to URP. <shrug>

[verbal apex]

I wonder if the falloff changes for progressive mapper if you're on standard pipeline vs URP; we definitely built new lightmaps in the standard pipleline with the progressive mapper and they were fine... 😕

[sharp nest]

hi guys someone can help me with a question of bake shadows ?

[turbid matrix]

@verbal apex pretty sure the progressive lightmapper does same falloff for all RP's but for dynamic lights the falloff is definitely different for built-in and SRPs (URP and HDRP)

@verbal apex there is supposed to be an option to swap it to the old "legacy" falloff setup though, see https://docs.unity3d.com/Manual/ProgressiveLightmapper-CustomFallOff.html

not sure if that is still in URP since well... I can see how Unity wouldn't want people to use that in URP

(old setup wasn't correct)

also I don't think you can adjust the realtime lift falloff so if you only did that for baked lights and still have mixed lighting, you could get really weird looking results

[tacit slate]

all materials are broken or don't compile at all on URP builds, everything works in editor. don't get any shader compilation errors. any idea what to do

tested on multiple different devices from the latest iphone to 6 year old androids, same issue on all

[pastel oracle]

Hey not sure if this is the right server but I don't know where else to put it.

I am looking for a way to stop z fighting in one of our clients' revit model.
We got the model and imported it in Unity but in the revit model there is an interior and exterior wall but with exactly the same measurements. the model is around 500mx300m with a lot of rooms so doing it by hand is just not the way to go.

Does anyone have an idea on how to solve it without doing anything by hand? Like an automated script or something? I googled it and found some articles but nothing that suits my case.

[cloud lantern]

in an HDRP shader, how would I get the view direction?

[turbid matrix]

@pastel oracle why is that z-fighting? or are you using double sided materials?

you'd think the interior and exterior walls's are faced in opposite directions so there's nothing that could cause z-fighting on the rendering

[pastel oracle]

Nope sorry I didn't explain that right. In their modelling software they made a building and they have 1 interior wall, copied it and made one exterior wall. What they mean by that is that there is a wall that's inside another wall. I don't know the english terms but it's like one wall on the inside that's for isolation and the other is for the looks and decoration. But they have the exact same measurements. Usually the wall on the inside is smaller and the one on the outside is thicker. But that's not the case here which causes z-fighting

I've made a tool that automates searching for those inner walls and I just disabled them

[rotund quiver]

How... is this over 300 batches? Stats gizmo says 300. Frame debugger says 22. Any other places where I can see draw calls?
(edit: ok, it's 300 many batches if the SRP batcher is off... then they show up in the frame debugger ... but ... it's on. what gives? URP 11.0)

[broken lichen]

The Stats window doesn't show correct batch numbers when using SRP Batcher.

[verbal apex]

This is the script we ended up using that fixed our baking eventually. Like you said, realtime falloff is calculated in the script, which I think we can modify, though we may just opt to not used any mixed/realtime instead.

Thanks for the info!

[halcyon moon]

I cant decided what render pipeline should i go with between URP and legacy 😦

[iron flame]

https://github.com/Unity-Technologies/Graphics/pull/5714

[rotund quiver]

After all this time they couldn't even make it not show conflicting data (no data would have been better). Thanks for the explanation.

[dawn sorrel]

Is it weird that I kinda want mutliple fogs simultaneously in HDRP?

Like I think having a generic height fog to mask the terrain cutoff with the skybox and also having a low opacity white fog that caps out at like 0.2 opacity would be neat.

[turbid matrix]

this is nice, altho pretty sure it'll take a long time till we see FSR in URP

they need to get this PR done before that https://github.com/Unity-Technologies/Graphics/pull/5346, then do the followup PR to the first one before they can even start working on URP FSR

only if you write your own conversion scripts for it

[flint willow]

I have a problem, i have a Universal Render pipeline project, it uses both 3D environments and 2D sprite characters, the problem being that the 2D sprites only care about their sorting layer, ignoring any and all perspective and just drawing on top of each other whenever.

tho some how they do respect 3D environments, if this can be solved, could there be a way to get lighting working with 2d assets aswell? Please and thanks, Dm me if you want.

[turbid matrix]

oh snap, just realized they also moved CAS shader to core, would be nice to get that one for URP too 🙂

[turbid matrix]

as a side note, I wish Unity would update the Graphics repo tags while the versions are still relevant

I love that the tags exist, it's just, they almost never update them in time when you get new engine versions... so if you are using a version that's like released within past 4 weeks, chances are that there will not be tag for it yet

for example, latest 2021.2 tag in Graphics repo today is for 2021.2.0b8 from July and we are at b12 already

this is kinda annoying because since SRPs moved into Unity core, being able to track the right version has become a major pain. these tags would help if they actually were updated in time

[marsh marsh]

I have tried to do blood stains on my characters in unity, but I haven't found a way to do this and I haven't found any useful tutorial. How are blood textures applied to surfaces usually in games?

[turbid matrix]

if they are permanent stains, people would normally just apply them to the base textures using texturing tools

for more dynamic ones you can use decals or do some shader which can blend your blood stains on top of the base material

@marsh marsh

[marsh marsh]

I see... Is it possible with materials? As in, the surface the blood needs to be applied to? @turbid matrix

[turbid matrix]

you'd need some layered shader for it, I can't remember if there were any provided on some samples or not

[rapid whale]

Hello everyone. I don't seem to be able to create sprites with a URP project. The option for creating a 2D Object by right-clicking in the Hierarchy doesn't even show up to me, and when I try to drag an image into the scene view, my mouse icon turns to a "blocked" symbol, so I can't add sprites like that either. Could someone help me with it?

[pulsar valley]

Anyone having issues with rendertextures getting corrupted in URP on M1 MacOS? - Broken when running a built version fine in editor and fine on intel mac or windows (built or in editor):

Seems to have a weird load order / chunking texture format type issue. Maybe a metal thing or something.

(rendertexture is used to do a low res effect on the main camera, UI is drawn on top in another camera in real screen space so is un-affected)

[inner parcel]

Most likely a bug if that works fine in other platforms. Just attach this in a bug report

thank you very much ❤️

[summer glacier]

https://forum.unity.com/threads/mega-runtime-performance-tips-thread-hdrp.1169837/
is a good start

[dawn sorrel]

Isn't it really stupid that Unity broke backwards compatibility for rendering with SRPs but then only made one of the pipelines use physically based light intensity units?

[keen tulip]

is it possible to change the upscaling algorithm for Dynamic resolution in HDRP at runtime?
I want to change between FSR and TAAU depending on scenes. I dont want to have multiple assets just to address this combination because I already have 5 different assets already

[inner parcel]

upscaling algorithm i think you can modify at runtime aswell.
there are few settings like SSAO which require you to have it enabled in the asset before compiling for stripping shader variants accordingly.
what you can do is, enable them at first in a separate asset in Resources folder, and then compile it. once you're sure that it has been there when it was compiled, i guess you can then modify the asset at runtime.
but im super against this and it might be highly unstable and break your game in Player despite working correctly in editor. so i'd advise you to just try it once in the player and see if that works for you

[keen tulip]

Thanks

[summer glacier]

I requested this a while ago and one of the developers thankfully made an API for it, no need to change assets. You can just use the API and directly change it.

I think it will be released in 2021.2

[keen tulip]

Where's the api for this? Not yet available in 2021.2? Any pull request for the same?

[flint willow]

I have a problem with grouping 2D Sprites with sorting groups. When i put the sprite into one, the position in world based layer sorting breaks completely, and it switched back to hierarchy sorting. I am doing all of this in a URP without a 2Drenderer

[summer glacier]

I don't think it's in the beta yet. It was merged to master a bit late into the cycle, not sure if it's already in or not.

[summer glacier]

https://github.com/Unity-Technologies/Graphics/pull/5240

[keen tulip]

Really nice! Though I'll go with malloc's approach meanwhile because there's no alternative even in the beta latest version

[flint willow]

Nvm i am stoopid, 2D sprites have a built in Z-ordering thing, the problem was that you need to put the Sorting Group on the ROOT game object, instead of all of the CHILDREN game objects

[little trout]

Where can i find Edit > Render Pipeline in unity 2022?

[hollow vine]

hi,
i have hi-res detailed human anatomy model with huge hierarchy ... and i tried to render it on Oculus quest 2 with URP 11 and got 30 - 40 fps ...
so, does exists any methods to optimizing frame rates without touching that model?? shader things or something like that :]
thanks.

[inner parcel]

most likely no. higher tris count is killing your performance and idt theres any way to efficiently tackle it other than replacing/optimizing the model

[hollow vine]

so ... does exists some methods to distance based combining models in realtime to decreasing draw calls? or similar methods??

[inner parcel]

the number of gameobjects in hierarchy is most likely not the reason you're game is suffering in terms of fps

you can combine meshes tho at runtime if you're interested.
https://docs.unity3d.com/ScriptReference/Mesh.CombineMeshes.html

[hollow vine]

you're right ... but i can't touch the model cuz of very small details for medical reasons :]
and i have about 3M tris on this anatomy!! with about 5000 gameobject ...

and another question ... does URP multithreaded on glES 3.x ?? or needs to some modifications??

[opal vapor]

Why do I keep getting this weird area where the alpha should be?

It shows up in the finished version too

[errant trellis]

how do i get global light 2d

i have the render pipline installed but when i go to find it in hierarchy its there but grayed out

[pulsar valley]

Yeah the intel version is fine running under emulation, just the apple silicon version shows this issue.

[turbid matrix]

@little trout if you are looking for URP material conversion scripts, they have a tool for that now, hence the removal of the old scrips in edit menu

you can access the new tool from Window->Rendering->Render Pipeline Converter

(this applies to all URP versions since 2021.2)

[summer glacier]

so in HDRP, you use reflection probes for interiors, to get rid of ambient lighting

it works, but leads to the room being completely dark from the outside. When entering the door, even though the room is lit inside, it looks completely dark until you get closer/enter the room.

Any workarounds?

that's the natural aspect of it. you can increase the lighting in room in that case.

when exterior light is much more higher than the interior light then your camera's exposure is adjusted for the exterior lighting. the overall exposure of camera is lowered to intake less amount of light leading to visible output. since the exposure for camera is reduced what you see inside the room looks completely dark

[shrewd moon]

Your shader is stretching/dilating the visible part of the alpha channel, so it reveals the background of RGB channels

[summer glacier]

Eh, I just remembered the Indirect lighting override. Works great for interiors. Still got some issues but with some work it'll probably look fine.

Btw they're adding light temp to urp

Guys is it possible we are seeing a performance drop on URP 7.3.1 with the latest Nvidia and SteamVR updates.I have no other explanation how our game went from 7-8ms to 15ms

Meanwhile our other game that is on a higher URP version does not have a perf drop

[opal vapor]

how do I fix this?

[shrewd moon]

I wouldn't know
It's an issue that's very specific to that particular chromatic aberration shader

[inner parcel]

maybe try to do a deep profile. if it's just the urp version which is different probably yeah.

also you gotta remember that SRP is a new thing and it's constantly evolving. HDRP has some crazy performance boost too from 7 to 12. If I were you I would be thankful to the devs working behind the scene and just continue with newer versions

[eternal laurel]

@inner parcel Im very thankful to the devs Its just a shoker that it was running fine nothing was changed on unity's end so I suspect either SteamVR or gpu drives. The profilling showed that XrRendering.waitforsempohore is taking 15-17ms

[inner parcel]

WaitForSemaphore sounds like a gpu bottleneck/vsync

[eternal laurel]

Also steamvr was suddenly upscalling to 125% by default for some reason

[inner parcel]

try to profile your gpu and see if there's any difference

I haven't any exp with steamvr but yes I do know that crappy drivers are hard to troubleshoot since I've had my bad experience with nvidia rtx drivers

[eternal laurel]

Thats the wierd thing GPU claims its taking 7-8ms

I did a very dirty test of disabling all geometry in the level that did not change a thing

[inner parcel]

WaitForSemaphore is usually cpu waiting for gpu before next frame.
Try to revert changes in your git if you have any setup

also is there any reason you're still in urp 7? isn't that like unity 2019 or 18?

[eternal laurel]

2019. Reason is that it was fine up until now and I did not want to change major versions cause of all the crazy stuff around openxr and the plugin from valve

Im suspecting that they updated something that does not play well with the old SteamVR integration

Other game that is running fine uses the new plugin

[inner parcel]

one more thing you can try is recreating the urp asset a fresh with same settings as old.
I had some performance issues in hdrp 4 or 5 idk and re creating the asset a fresh every time fixed that issue temporarily.
I had a crappy pc back then or maybe it's fixed now but I don't notice it anymore

[eternal laurel]

We havent made any changes that will impact perf on our end

I could try that but the steam release also has the perf problem

And we dont push a production build unless it meets the fps requirments

Only two things that have changed are steamvr and nvidia drivers

[inner parcel]

that's a good practice. but at some point you gotta take the pain to move to the unity's new XR system in 2020.
I had to go through the same for oculus plugin for unity 2020 but with the free performance boost (more battery life basically) I'm happier

tho that was in built in, not urp

[eternal laurel]

I guess its worth the test tomorrow yeah

There were some patch notes on them changing some buffers so that it takes less vram for their composer

Maybe the old stuff doesnt like that haha

Im just sad that if this fixes it we will have to redo all the input yet again

[inner parcel]

just hope that there's no new big change in unity's xr. OpenXR is considered to be the final state and let's just believe in khronos team

[eternal laurel]

And the two valve guys that are making the unity plugin for steamvr

Bless them

[turbid matrix]

@eternal laurel that does indeed sound like some frame timing issue

I had something like that on URP 11 which was caused by some silly change Unity did on URP but that change doesn't apply to URP 7.3

like, it's not directly related to it

if it really is driver or steamvr update that broke it, I guess the only thing you can do then is to see what is the change in Unity that does make the newer versions work fine (step one is to make repro on the urp 7.3.1 breaking and urp 10 working on totally different project)

or just... make 7.3.1 repro project and report it as a bug :p

but like, I'd probably try to narrow it down where and when it broke as it's easier to find the root cause

[eternal laurel]

well first thing Im going to try and upgrade unity and urp and see what happens

[turbid matrix]

that could lead to other things breaking too 🙂

[eternal laurel]

oh Im well aware of that 😉

[inner parcel]

at some point he needs to. unity 2019 is reaching end of support for mrtk by end of this year. cant imagine other providers to maintain older version of unity too, especially since XR has some breaking changes in 2020 which is hard to maintain (for the sdk providers)

[turbid matrix]

2019 LTS support ends next spring once 2021.3 LTS is out

[inner parcel]

i didnt mean unity 2019 lts

https://github.com/microsoft/MixedRealityToolkit-Unity/issues/9597

[turbid matrix]

unity 2019.1 - 2019.3 support ended 1.5 years ago though

ah, you meant that toolkit, ok

[eternal laurel]

I will report back with what the updates do

[inner parcel]

no you still didnt get my point. i wasnt talking about unity 2019 LTS reaching end of support
microsoft's mrtk (which i consider is the biggest xr sdk) itself is deprecating 2019 by this year. i would expect other providers to end it soon aswell because from their perspective, its hard to maintain OpenXR for both unity 2019 and unity 2020 because the amount of changes between them is too big

[turbid matrix]

yeah I got that really meant mrtk 🙂

[inner parcel]

heh 😄

[sterile mesa]

in hdrp, how do you make a mesh absorb more lighting (aka be brighter than stuff around it without necessarily emanating light itself) in the inspector?

[fleet path]

is it possible to disable the HDRPGraph that shows up with certain controller combinations? For whatever reason I'm getting it on right trigger - which makes it a nightmare to test

[turbid matrix]

answered on #🖱️┃input-system

[exotic plume]

Hiya been a while. Got a few questions about using pathTracing for “offline” rendering. Approximately how many accumulation samples should I use for a very simple scene with one spotlight - to get clean noise free images. ???

Should I use any screenSpace PP with PathTracing if render time is not an issue and I’m trying to get the most physically accurate result???

[inner parcel]

make sure to remove this in HDRP asset. all of the assets if you have multiple of them.
It's not a bug. It's a feature most URP users are dying for 🙂

[dawn sorrel]

lemme try

in this @inner parcel ?

[inner parcel]

yes

[dawn sorrel]

i dont see any settings to change\

[inner parcel]

Exposure should be there IIRC

under lighting

[dawn sorrel]

what setting is it called tho

[inner parcel]

my bad. maybe it's there only in frame settings.
anyway, go to the scene where you want to disable the light thing.
Find your camera, enable custom frame override

Then find exposure like you did before

make sure the tick mark on left is enabled and the tick mark on right is disabled

that should fix it

[dawn sorrel]

I dont even see that

I wasnt even using a camera yet

[inner parcel]

if you want to fix that for scene view aswell then in that case go to player settings, default hdrp settings and disable exposure control there

[dawn sorrel]

i tried that and my screen got really bright, like extremely unbearable

[inner parcel]

yes that's bound to happen. without any exposure control that will happen

another option you have is to re enable the exposure back from there.
And then find hdrp volume and then change it to fixed exposure. then lower the exposure value until you're comfortable

[dawn sorrel]

ok

[inner parcel]

https://youtu.be/yqCHiZrgKzs
if hdrp feels overwhelming just go through this complete video once. you'll understand it better

[dawn sorrel]

its just not working, i legit have nothing now

no skybox

[inner parcel]

if everything is just "not working" for you then I can't help. if you go through the video you'll know why the skybox is missing

[dawn sorrel]

hello, I don't know where to ask this question, I hope someone here can help me...
shadows in my project are showing like this ... and I have no idea why that's happening

[turbid matrix]

nobody can help you unless you tell what you think is wrong, to me that looks like normal shadow

[dawn sorrel]

doesn't it look like it is very... (idk how to describe it but look at the edges of the shadow.. they are very NOT smooth)

[turbid matrix]

@dawn sorrel run through HDRP Wizard, it's somewhere in the window-menu (under either rendering, analysis etc depending on your hdrp version), once it's all green make a new scene with Unity editor, you'll get a scene preset for HDRP lighting values

@dawn sorrel if it's URP, you can enable soft shadows on URP asset

[dawn sorrel]

I am using URP

where do I do that?

[turbid matrix]

I have no idea where your urp asset is located 🙂

[dawn sorrel]

oh the asset not settings or preferences

will do it

THANK YOU

it worked

[turbid matrix]

np

you can also play with the shadow settings there

like change the resolution, cascade amount etc

shadow distance affects the look directly too

I've seen 2 cascade setting with soft shadows working quite nicely on URP

[eternal laurel]

@inner parcel @turbid matrix after updating to 2020.3.18f1 and urp 10.6.0 we are back to 7ms. I wonder if I should just go up to 2021 and urp 11 at this point. How ever my custom blit is now broken. 0lento I remember you had a working example or was talking about some work around

[turbid matrix]

@eternal laurel if you mean VR SPI being broken with cmd.Blit, that's been like that throughout 2020 cycle I think?

I do have example of the drawmesh approach here: https://github.com/0lento/URP_RendererFeature_SPI_Example

do check the commits there as they highlight the required changes

should probably also omit that last commit from the repo (or at least put it into separate branch) as it relies on OpaqueTexture which users can downscale from URP settings (which isn't what you usually want)

I wouldn't really go for URP 11 at this point anymore, 2021.2 is getting closer to release and URP 12 is what the 2021 LTS will be using as well. URP 11 /2021.1 support ends in few months when 2021.2 is out

[eternal laurel]

oh wow I guess I've fallen behind a bit haven't I haha. Once I get this to stable I might as well bump to 12 straight away

[eternal laurel]

so good news XRStats.TryGetGPUTimeLastFrame is still broken

[turbid matrix]

I always wondered about those XR GPU stats... most of them never did anything for me so I just assumed they might work only on some device and renderer combos

[eternal laurel]

I think I know what happened now

the steamvr compositor started delivering wrong frame timings

so steamvr was upscaling to 125% by default and then my custom dynamic res was getting the wrong data so was doing a x1.4 pass on top of that 🙂

[exotic plume]

Ugh…. My questions get buried when ask them on discord. 😞

I guess I should just post on the forum

[turbid matrix]

there are probably more path tracing users on the forums too, it's not a topic you see a lot here

[summer glacier]

https://github.com/Unity-Technologies/Graphics/commit/53624e96d78405b64dafae592ce4c443ef0afb09

exposure being added to urp

[turbid matrix]

I'm kinda reserved on that one

while it's cool when it works, it's really often broken on various places in HDRP

it's also something that new users do struggle with (but for that I blame how HDRP is set by default)

this doesn't mean they will add real-world lighting units for URP though, could be just for auto-exposure

https://portal.productboard.com/8ufdwj59ehtmsvxenjumxo82/c/221-automatic-exposure

[dawn sorrel]

Anyone know why my postprocessing doesnt work?
I have the camera Postprocessing enabled,
volume is set to global and enabled as well and I put the urp asset in the graphics setting

[turbid matrix]

@dawn sorrel go to your URP data asset (the one that your URP asset references) and enable PP from it

also in case you have multiple such assets, make sure you actually enable it from currently used asset

[dawn sorrel]

wai what..

its enabled though ... @_@

@turbid matrix idk what im missing :C

[undone pecan]

@dawn sorrel check that you dont have multiple post pros in game. happends to me alot.

[dawn sorrel]

volumes?

[undone pecan]

they tend to fight over control over the PP

[dawn sorrel]

this is a new scene ... and i added only one >_>

[turbid matrix]

wait, you are using the old PP package?

it's not supported on recent URP versions

[dawn sorrel]

idk.. i used URP template

[turbid matrix]

which URP?

[dawn sorrel]

on latest unity 2021..

[undone pecan]

if you have a new scene with extra stuff, you might have a PP setup from start

[dawn sorrel]

i thought it would just be working 🤔

[turbid matrix]

well, that one definitely doesn't use PP package

[dawn sorrel]

But it had pp installed

2.x

[turbid matrix]

it didn't have that if you really used Unity 2021.1 or 2021.2

[dawn sorrel]

i tried updating it in the package manager to 3.1.1 and didnt help

[turbid matrix]

URP 11 or 12 don't support that PP package

you have to use URP's own volumes, not the PP ones

[dawn sorrel]

😵‍💫

[turbid matrix]

you should just uninstall that PP package with URP, it's only mean for built-in renderer there

last URP version that supported PP package was like 7.x

(or 8, can't remember for sure)

[undone pecan]

welcome to PP hell 🙂 but when you get the hang of it, youll remember what NOT to do 🙂

[dawn sorrel]

So I just uninstall bboth?

[turbid matrix]

no

you just uninstall Post Processing package if you still want to use URP

[dawn sorrel]

urp is for shadergraph right

so there is no post processing in urp anymore?

[turbid matrix]

it's a completely different renderer, it's not just for shader graph

there is, but it's not that old one, see https://docs.unity3d.com/Packages/com.unity.render-pipelines.universal@11.0/manual/integration-with-post-processing.html

[dawn sorrel]

oh so i have to get the new one

ok...

[undone pecan]

there is yes. but a more lite PP

[turbid matrix]

it has one built-in, nothing you install separately

[dawn sorrel]

huh

why they changed it?

[undone pecan]

they changed it for the better

[dawn sorrel]

I see

finally lol it shows in game view

thanks

^^

[undone pecan]

remember to check if you have multiple Profiles in use. or they fight over the PP

[gritty crag]

im trying to make a grid with vertex position in shader graph but it doesint want to interact with procedural shapes at all. is there a reason or a work around?

[dawn sorrel]

how would i do that? but it seems to be working now so thx

[undone pecan]

that FAE_postprocessing.... name under Profile. that is your current one. hunt if there is more, or if you want to make your own custom one, you have to switch off the current one in the editor/preferences

[dawn sorrel]

the profile is from an asset

there is a few

i created a new one tho

[undone pecan]

then get rid of the old and just force feed the new one so its the only one in use. good luck

[dawn sorrel]

but shouldnt it be already using new one since i selected it

[undone pecan]

like i said, you could have multiple in use.

[dawn sorrel]

With vignette i can do a scope effect. can i enable/disable that in code? 🤔

[undone pecan]

you can.

[dawn sorrel]

I searched in the hierarchy for "Volume" it only showed that one

How expensive is FXAA on mobile?

Is this really how to get the vignette effect and disable it? https://forum.unity.com/threads/hdrp-2019-1-how-do-you-change-effects-volume-overrides-through-script.668842/

cant seem to drag and drop the vignette itself in inspector

ok yeah the tryget makes sense i guess

[dawn sorrel]

noice now i got an easy scope heh

[sinful locust]

How to get the camera world position with HDRP?

I see some references to shader field values, but surely there is some helper method or something to extract them?

[long dagger]

So i made my character 1.7m tall( used unity's default cube as a reference) but shadows looks really bad and pixelated, however when i scale it x10, it looks okay, Why? Isnt the default unity cube sized relative to real world?

I modeled the character in blender and sized the model by going back and forth between unity and blender using unity's default cube as a reference.

[dawn sorrel]

I think you have to play with shadow settings a bit on your light 🤔

the right one looks more like a hard than soft shadow tbh

[long dagger]

@dawn sorrel soft shadow is ticked, i played around wirh cascade settings and somehow got a decent result but shasows are still really bad

[dawn sorrel]

Are you on highest quality? 🤔

[long dagger]

@dawn sorrel okay i got it, i increased the cascade count to 2

@dawn sorrel but cant use soft shadows, my characters shadow becomes a stick figure

[dawn sorrel]

hmmm

weird

the shadow does look creepy tho 😰

[long dagger]

@dawn sorrel got it! cascades are the way to go, looks perfect now.

[dawn sorrel]

neat

[still charm]

question for URP, if anyone here has written any scriptable renderer features. I want to control some of the variables in my settings in the feature, and it seems like the easiest way to update those is to change them and then call .Create() again. That ... feeels wrong, so instead I added in some Update(settings) functions that overwrite the settings variables inside of the pass. is that a better way of doing it?

[gritty crag]

The normals look really pixelated?? fed sub shader grid into Normal from Height. Also if I were to detect if an object is below one of these boxes to see if I want to put a light there using shader graph, how.

[turbid matrix]

@still charm you can feed in the new values at AddRenderPasses since it's going to be called every frame anyway, like this: https://github.com/0lento/URP_RendererFeature_SPI_Example/blob/main/Assets/RendererFeatures/SaturationRendererFeature.cs#L17

but in these, I'd go with "whatever works"

[turbid matrix]

https://forum.unity.com/threads/focusing-on-shaders.1171444/

[summer glacier]

Same actually. Could create a lot of headaches for some people, we'll see how it's treated in urp

The nice thing about urp imo, is you don't get headaches working with lighting. That headache brings some advantages but still, a bit painful 😄

https://github.com/Unity-Technologies/Graphics/pull/3174
merged a while ago but I tested github master and a pretty big difference. And downsampling is sort of a must for most, big perf difference.
prob in beta or alpha by now actually.

[turbid matrix]

@summer glacierthat's from April though, it should have been in 2021.2 alphas already?

that change is mentioned here btw 🙂 https://docs.unity3d.com/Packages/com.unity.render-pipelines.universal@12.0/manual/whats-new/urp-whats-new.html

URP 12 will be such a nice release once they get it all stable

[summer glacier]

Really need TAA though. Specular aliasing hell everywhere.

[turbid matrix]

yup

been using this for my urp testing atm https://assetstore.unity.com/packages/vfx/shaders/fullscreen-camera-effects/urp-taa-193976

[summer glacier]

Gif rules, yeah.

[long wagon]

@summer glacier No reaction gifs, please.

[summer glacier]

🙂

[turbid matrix]

it's nice, does movecs too but uses old cmd.blit so it's totally broken on VR SPI

I'll probably try porting HDRP TAA to URP later anyway but it's nice to have something you can just drop in

[summer glacier]

Does it not use motion vectors?

[turbid matrix]

it uses movecs

"Use Motion Vectors to improve anti-aliasing quality of moving objects. (This feature requires URP 12)"

[summer glacier]

Nice.

I imagine TAA will land in 2022 for URP, otherwise, seriously big disappointment.

[turbid matrix]

yeah it really should

[summer glacier]

And maybe... volumetric fog? or is that being naive? 😄

[turbid matrix]

but I also totally expect them to do some more bare bones TAA for URP than what they did for HDRP

yeah, I'm not expecting volumetrics at all

considering they are really focused on first getting more feature parity with built-in, I wouldn't expect any rush on new things

I'd personally want to see VT's being supported but I'm guessing that new shader system has to land before it happens

[summer glacier]

2 much time spent on feature parity with built-in, should've been good to go by 2021

taking way too long. I can't not rant about the time it's taking lol.
