#

Ok thanks for the info, but can I have the sun in the sky without real time lighting?

elder shore
#

Sure, you could use a skybox without a sun, and move a object to emulate the sun, you wont have real time shadows tho

#

A classic approach can be found in Legend Of Zelda, where they load different scenes for different times of day

marsh marsh
#

So using that, I can only use baked lighting?

elder shore
#

🤔 That error only happens when you dont have the using directive present for the thing you want

elder shore
marsh marsh
#

Aw jeez.

#

But the thing is the FPS drops only with the day cycle script

elder shore
#

Well, you can always keep the scene size small with some less than 100 really effiecient game objects

#

Then real time lighting shouldnt be an issue

#

Recently, Sword Art Online just recently did a real time lighting scenario where they just reloaded the scene every 20-40 meters

#

To get past the issue

#

But the loading was so frequent it was a disaster

marsh marsh
#

right

#

but yea, like I said, its the day cycle that causes FPS drops

#

How would one make an efficient day cycle with real time lighting?

elder shore
#

Night cycles wont be inefficient because there are no shadows to bake in real time

#

To make day run more efficiently, you can reduce the shadow quality to very low, and keep the scene object count low

marsh marsh
#

Ok im gonna try that

elder shore
#

Im sad to say real time lighting is not "there" yet

#

Its computationally too expensive for most home computers

#

So you have to be really gentle about shadow quality and object count

marsh marsh
#

Im sad too, especially when the guy's that showed the tutorial for that day cycle script FPS didnt even budge

elder shore
#

Was he running it on a 6 thousand dollar computer?

#

If so, yeah you can push more shadows

#

Honestly real time lighting is a feature most gamers wont even notice, as they run threw towns in 50 seconds

marsh marsh
#

Im not sure what kind of PC he had hahaha

#

but yea you got a point

elder shore
#

Id rather have high fidelity towns with a fixed day light bake

#

Then a low fidelity town with realtime lighting

#

If I need a night scene, I just copy the scene and give it a night bake, and have a manager to communicate what the day/night scenes need to have in common

marsh marsh
#

Ok I found a solution!

#

@elder shore Thanks for your help though!

elder shore
#

Yw

elder merlin
#

I'm not comfortable with what's being presented as facts here

#

a lot of games use realtime lighting

#

Sometimes it's a necessity, like when dealing with open worlds, or with day/night cycles like are asked about here

#

And you don't need run a $6000 pc either, breath of the wild uses fully dynamic lighting

marsh marsh
#

Yea I was kind of thinking the same, games like GTA use real time, and the map is huge too

elder merlin
#

In those cases baked lighting is not even an option

marsh marsh
#

Yea but do you have an another solution for my FPS problem?

elder merlin
#

You're running HDRP? What are your specs?

#

HDRP is meant for higher end computers

marsh marsh
#

HDRP, Ryzen 5 2600X with GTX1070 and 16gb of ram at 3,6ghz

#

that should be enough of computing power for developing this game

#

its low poly btw!!!

#

im going for a triple A low poly type of thing, it looks really nice even right now

elder merlin
#

When you run into these things you'll want to use the Frame Debugger to figure out what is eating up your FPS

#

The stats window in the game view will give you an indication but it's got some problems in HDRP

marsh marsh
elder merlin
#

That's the stats window

#

The frame debugger is under Window>Analysis

marsh marsh
#

Oh I found it

#

and now I run the game and it will show me a graph or something?

elder merlin
#

it will show you each step of the rendering process

marsh marsh
#

Ok, so how will I know something is wrong?

dawn sorrel
elder merlin
#

It won't tell you what's wrong, just what's happening

marsh marsh
#

Right, but how can I tell whats normal and whats not

#

or what should be happening and what not

elder merlin
#

If you have a specific issue with your day/night script then see what changes when it's enabled and when it's not

marsh marsh
#

alright

elder merlin
#

Also if you haven't used it before, watch some tutorials to get an understanding of what it's showing you

marsh marsh
#

I will thanks!

dawn sorrel
#

i can only add a single override to a volume, the second thing i add just disappears and it says SerializedProperty components.Array.data[1] has disappeared! in the console
does anyone know why this happens (im using hdrp but it also happened in urp)
or is this the wrong channel to ask

marsh marsh
#

I have a camera with a render texture for a sniper scope in HDRP, and it causes FPS drops when I swap to that sniper. Can anyone tell why?

frigid quarry
#

check frame debuffer

#

or profiler

inner parcel
#

using 2nd camera isnt recommended for hdrp. depending on your unity version, try compositor @marsh marsh

marsh marsh
#

@inner parcel How are scopes and stuff like that done in HDRP?

inner parcel
#

compositor might work for you

marsh marsh
#

I looked that up in youtube, I dont get it, what does the compositor have to do with scopes?

versed quarry
#

I just got this sinking feeling in my stomach... the default renderer is not URP as I gather now and I read that URP is more efficient? does that mean my work so far was on outdated tech?

broken lichen
#

URP is more performant by default, but that doesn't mean you can't get the built-in render pipeline to perform just as well or even better.

#

It's easier to make something with URP and get good performance. It requires a bit more work and optimizations to get the same performance with the built-in render pipeline.

#

The main difference is in the realtime lighting and overall shader complexity

#

The default URP/Lit shader is supposedly not as complex as the Standard shader, but of course you don't have to use the Standard shader.

#

If you use a lot of realtime lights, URP is better than built-in. But you can make your own custom lighting system that performs similarly or even better than URP in the built-in render pipeline.

versed quarry
#

thanks for the info!

#

I dont have any real time lights at all, all custom stuff really

#

so that is a relief. I was really just trying to find out if there is an event that I can get when rendering is done for a frame and stumbled onto renderpipelinemanager that did not work at all.

#

as I guess it's limited to the custom renderpipeline what sucks a bit.

broken lichen
versed quarry
#

yeah I know about that, but I need the event after everything is rendered not just a camera. I wrote an android plugin and when I call it in post-render it still intereferes with unity rendering. the error is in a blit function within Unity after my plugin successfully finishes. The plugin creates an MP4 and also does some rendering. I'm not even sure if my idea will fix my problem though

#

thanks for taking the time to hear me out @broken lichen

that said, Built in RP is still supported / not deprecated and is very tried and true, with a wealth of resources around it. There are many features that URP doesn't have parity on yet. So, many reasons that one might want to use BRP still today even if it's not the most optimized or doesn't have the latest features out of the box.

waxen lantern
broken lichen
#

@waxen lantern I agree with all your points. I don't think they negate my points though. SRPs will always be able to outperform built-in in every use case because they can more easily be customized and optimized for the specific render pipeline you need. My point was more about unmodified URP and a "modified" built-in renderer being comparable in performance, at least in the forward renderer.

#

The forward renderer is so simple, there's only so many optimizations you can do. The built-in has a terrible way of handling realtime lights by doing additive passes. URP does it much better by doing it single pass.

But since all this is implemented in the object shaders and with some lighting data passed from script, it's not too difficult to implement your own single pass lighting in the built-in renderer. The Lab Renderer did this and I'm doing it in my own project.

#

Not that I'm recommending everyone should do that over using URP. My point was more about if you have an existing project using the built-in renderer, it's very possible to optimize it to the same level as URP's default performance.

Does anyone happen to know if HDR within URP is supported by Nintendo Switch? I can't seem to find a definite answer online...

#

problem is I can't get the android version to run

#

idea is that the user can export an mp4 of what he has created

#

to encode the mp4 without adding extra libraries I need to use built-in encoder and it's been a real pain getting there. I've managed it on ios and I've successfully created videos on android. but after creating the video in java, unity crashes due to some null pointer exception in a blit function. the function is called right after my java code is done (after the share was successfull). I think the gl stuff in the java code is overlapping/interfering with unity rendering and I was hoping that if I can do all my operations when unity is done, that the problem will go away @waxen lantern

broken lichen
#

@versed quarry Rendering in Unity is done on a separate rendering thread. None of Unity's rendering events are invoked during this rendering thread. Instead, all GL commands done from C# script are queued to be executed later in the render thread.

#

But invoking GL commands in Android Java code will happen immediately.

#

The only way I've found to get a callback during the render thread is with a native plugin and GL.IssuePluginEvent

#

You can use the native plugin just as the hook and then either invoke Java code directly from the native plugin using JNI, or even call back into C# and do whatever there.

grave geyser
#

any tips on making the horizontal plane less obvious when using the HDRP fog?

versed quarry
#

@broken lichen the blit causing the null reference exception does not originate in my code. but what you are saying might mean my idea of calling to a different time will probably not work. maybe I am somehow overriding/deleting a texture or framebuffer required by unity. I just assume that is possible.

#

thank you a lot for your help

broken lichen
#

That is possible. If you're calling into Android Java from OnPostRender and calling GL commands there, I believe those commands will run before Unity makes any of its own GL calls.

versed quarry
#

I guess I will have to find out which calls are creating the problem, tedious but... hopefully this will work

Is it okay to not explicitly release a temporary rt? I've two cameras, during Cam A rendering I copy a texture to _MyTexture, during Cam B rendering I need access to _MyTexture, if I use any cleanup event from the scriptable render pass to release the RT, it throws a warning saying it can't find the texture, otherwise it works fine

I'm trying to use the Collide with Depth Buffer node within the VFXGraph in URP. It seems supported but no matter what I do I cannot get it to work!

#

is it just silently not supported?

hello, why the requirement of URP is physics? can i change it?

keen glen
crude cosmos
#

im not using 3d physics

keen glen
crude cosmos
keen glen
#

So did you try it or not?

#

If you cant disable the package because of URP, just stop the simulation and the beginning of your app

crude cosmos
#

no, i can not run any code, i have compiler errors when removing physics.
I can disable physics, but i dont want editor physics components. because my team choosing them not 2d physics

keen glen
#

YOu are making a game but cannot run any code? I dont get your situation, sorry. Thats the solution I can think of. If urp needs components of physics, thats what you have to deal with.

#

I would let the physics enabled and just disable them by code.

crude cosmos
#

i need 2d physics and i want remove 3d physics components from engine components lists

bleak otter
#

I guess URP just isn't made to support this use case

keen glen
#

Jesus... URP NEEDS physics, so keep it enabled. but use the code I wrote above to disable the simulation of 3D physics.

#

physics2d will still be running

bleak otter
#

If it's just some high level components of URP depending on it, you probably could fork URP with them removed/changed.

whole fossil
#

or make some sort of validator / editor tool that can help you with your use case

turbid matrix
#

it does sound a bit of an odd requirement though, considering we may want to run DOTS physics too (there's 3 differed 3D physics engines for Unity)

#

anyway, I can totally understand one wanting to get rid of that module. going for 2D and removing modules manually does suggest they want to do a mobile game and adding physx binaries to the build for no good reason will just make the installation size notably bigger

#

if it indeed is still required for 2D renderer on URP, I'd file a bug report @crude cosmos

trim bone
#

i think at the least for any volume related things it needs a box collider which (3d)physics lends as well as gizmos. kind of a hacky dependency but then again there really shouldnt be a problem just leaving the builtin package enabled and disabling the autosim as twentacle stated

turbid matrix
#

only real downside is increased distribution size with mobile

#

well, and some other wasted resources at runtime since it still needs to create physics world for physx and consume some memory for it

# daring lodge I'm trying to use the Collide with Depth Buffer node within the VFXGraph in URP....

VFX graph depth collision is not supported for URP (yet,) in any version of Unity. you can track this feature here on the VFX graph roadmap https://portal.productboard.com/unity/1-unity-graphics/c/97-urp-support-compute-capable-devices-only-lit-particles-and-various-features-and-fixes

We're working on support to make it possible for you to do things like render lit particles or using depth buffer collision using URP.

* Slight jump on clouds when entering a volume with volumetric fog
* Support for Planar / Probe / Ray Tracing
* Some Parameters like (Wind orientation, clouds altitude.. ) still aren't suited for blending properly
* Quality settings for primary steps and light steps

It is a dirty hack though, had to edit the Visual Effects package to change all Texture2DArrays references into Texture2Ds (just for the camera scripts though)

there's a threshhold

it should just be two classes

waxen lantern
daring lodge
#

oof, one of the things I modify is a struct used in basically everything, pretty sure it's easier to fork it

waxen lantern

@daring lodge yeah unless you want to duplicate or inherit from the struct

#

or rather.. C# structs don't support inheritance, i'm used to it in other languages. they do support interfaces at least

#

but yeah it can get squirrelly like this sometimes

I'm really struggling with trying to render a single unlit object in a performant way with HDRP, hoping somebody can miraculously help me

broken lichen

HDRP
performant
UnityChanLaugh

main rune
#

I've tried:

  • Single frame renders with a camera (set to not render any fancy things like light or shadows) > Had a HUGE performance overhead
  • Command Buffers > did not respect calls to change the view and projection matrices of the camera, Unity haven't responded to my bug report yet
  • Immediate GL > Does not actually draw immediately, meaning the changes to the camera / matrices have to persist over a frame for it to have any effect
#

Also custom passes > they can't access object data

#

Over the last week I was able to trivially get it working in Unreal Engine 4, so what I'm doing can't be that stupid

#

Though I'm not tooting unreal's horn here, that engine made me want to scream into a pillow

broken lichen
#

What's the reason you're not using a regular MeshRenderer for this?

main rune
#

Because I need to write the object's material output to an RT

broken lichen
#

Do you need any of HDRP's rendering with it?

main rune
#

Absolutely not

broken lichen
#

How were you using the command buffers?

main rune
#

Let me see if this is legible

broken lichen
#

Creating them and executing them with Graphics.ExecuteCommandBuffer?

main rune
# 
        CBuffer = new CommandBuffer();
        CBuffer.name = $"{gameObject.name} Damage";
        CBuffer.BeginSample($"Damage {gameObject.name}");
        CBuffer.SetRenderTarget(Damage);
        CBuffer.ClearRenderTarget(true, true, Color.red);
        Matrix4x4 projMatrix = GL.GetGPUProjectionMatrix(ProjectionCamera.projectionMatrix, true);
        //CBuffer.SetViewProjectionMatrices(Matrix4x4.identity, projMatrix);
        CBuffer.SetViewProjectionMatrices(ProjectionCamera.worldToCameraMatrix, ProjectionCamera.projectionMatrix); // > This straight up doesn't work at all, nor any variation of parameters
        CBuffer.DrawMesh(GetComponent<MeshFilter>().mesh, Matrix4x4.identity, DamageMaterial, 0, -1);
        CBuffer.EndSample($"Damage {gameObject.name}");
#

And then in update calling Execute, yes

broken lichen
#

Btw, what's the solution for this in UE4? I was just recently looking for a simple DrawMesh function that I couldn't find.

main rune
#

Screen Capture Component 2D or something like that. You just isolate the object and perform a colour only render to a texture

broken lichen
#

What unlit shader are you using?

main rune
#

Which would be great in Unity if HDRP didn't for some reason give 9ms of overhead to Camera.render or whatever

#

In Unity?

broken lichen
#

Yes

main rune
#

It just performs a UV unwrap and assigns the object position as colour

broken lichen
#

Okay, I was just making sure it wasn't an HDRP unlit shader. I think HDRP does some custom view projection matrix stuff that probably needs to be handles specifically in the shader.

#

Though now I'm wondering if just having HDRP assigned as the render pipeline changes the behavior of SetViewProjectionMatrices

main rune
#

If it does, it's entirely undocumented

broken lichen
#

Maybe try the HDRP/Unlit shader?

main rune
#

The shader doesn't matter

#

It's the perspective. The object renders fine

#

But it renders from the perspective of the main camera, and doesn't change

broken lichen
#

You could pass in the view projection matrix manually through a matrix property.

main rune
#

To the shader?

broken lichen
#

Yes

#

The UnityObjectToClipPos macro just gets a global matrix uniform that Unity provides

main rune
#

And then move the mesh to display correctly in front of the camera?

broken lichen
#

Move?

#

Oh, you're using Matrix4x4.identity in DrawMesh. Why not use the transform matrix of the object?

#

transform.localToWorldMatrix

main rune
#

Because I want it at 0,0,0

#

With no rotation

broken lichen
#

Is the ProjectionCamera pointing towards 0,0,0?

main rune
#

Yes

#

But again, it's not the 'wrong' perspective in terms of math, It's just not moving the vp Matrices off the main camera

#

I tried to add it into the camera's rendering via addcommandbuffer but that doesn't run at all in HDRP IIRC

#

I also tried GL

#

None of this worked

#

Because the GL draw doesn't actually happen immediately I suppose, but a little bit later

#

And for some reason GraphicsFences are saying they're compatible with my system but causing exceptions when I try to use them

broken lichen
#

I would keep trying the command buffer route, but try passing in your own matrices.
UnityObjectToClipPos is defined as:

inline float4 UnityObjectToClipPos(in float3 pos)
{
    return mul(UNITY_MATRIX_VP, mul(unity_ObjectToWorld, float4(pos, 1.0)));
}
#

Since you want the object with no transformation, we can ignore the unity_ObjectToWorld matrix multiplication

#

You just need to replace UNITY_MATRIX_VP with your own view projection matrix that you pass in manually.

#

It should be GL.GetGPUProjectionMatrix(ProjectionCamera.projectionMatrix, true) * ProjectionCamera.worldToCameraMatrix

main rune
#

Hm I see, that sounds promising. Thanks for making the maths easy too, I understand matrices mathematically and functionally but not intuitively

broken lichen
#

I made it easy because I don't understand it intuitively either 😄

main rune
#

Ahahaha ah well. I had a teacher once tell me to suffix "for kids" when researching something to make it easy, so maybe there's something to it

broken lichen
#

I hope they aren't trying to teach matrices to kids :P

tribal cipher
#

does anyone know why cmdBuffer.DrawMeshInstanced() would work in editor/play mode, but not in build?

#

I've like super duper triple checked that the material has instancing enabled, and it does

broken lichen
tribal cipher
#

is the instancing flag a shader_feature rather than multi_compile?

broken lichen
#

There's a specific setting for it in Project Settings > Graphics. Default is Strip Unused.

#

There's multi_compile_instancing

#

Which is probably a shortcut for something else

tribal cipher
#

hm

#

I'll try it, thanks!

#

oh what there's a specific setting for instancing variants? the heck

unknown.png
broken lichen
#

I think with Strip Unused, Unity must find a material with instancing enabled being referenced in some way in one of the included scenes to not strip it

tribal cipher
#

goodness it works, thanks a ton

broken lichen
#

👍

tribal cipher
#

then the next question is how I should solve this, I feel like forcing all my users to turn off strip unused would be a little too much to ask

#

is there a way to force them to be included? my shaders are already in a resources folder, which, I thought was enough to force include them, but I guess that skipped the variants anyway

broken lichen
#

If you don't have a ridiculous amount of variants in your shader, you could automatically add it in the Always Included Shaders list, which is also under Graphics in Project Settings.

tribal cipher
#

I do have a ridiculous amount of shaders and variants

broken lichen
#

👀

main rune
#

Freya... Shapes?

tribal cipher
#

(this is for shapes yeah)

broken lichen
#

Do you also have materials in Resources that have instancing enabled on them?

main rune
#

Ah, that makes sense.

tribal cipher
#

nope, just the shaders, so I guess that's why it doesn't consider it being in use then

#

I feel like there has to be a better way than to include a bunch of dummy materials

#

but I might have to do that regardless

broken lichen
tribal cipher
#

oh, cute

broken lichen
#

ShaderStripper uses it for complete control over shader stripping.

#

But forcing it to include all the variants is also a bit iffy. Either you preload all the variants at start and have loading time suffer for it, or have Unity compile each new variant as it sees it, meaning stutters each time it sees a new variant.

main rune
#

I mean the former isn't too out there these days

#

It's not great, but there's already precedent and not too much complaining. Horizon Zero Dawn and Detroit Become Human both have these ludicrously long shader compile times

tribal cipher
#

I just don't want more emails from people being sad about build/compile times ;-;

broken lichen
#

If you really wanted to, you could try to detect what variants the user needs based on what immediate calls they're using and only include those

tribal cipher
#

it's also weird to force that setting I feel like

#

that would be hard, I would have to write code analysis

#

(not to mention slow)

broken lichen
#

Yup. A little easier would be to show some checkboxes to the user about what features they want to include. Then at least they can blame themselves if they forget to enable some set of variants.

#

(but I'm sure they'll find a way to blame you)

tribal cipher
#

they always do

broken lichen
#

There is also ShaderVariantCollection and the "Preloaded Shaders" list in Graphics. I'm not sure if Unity will make sure to include all the variants in the collection there.

#

It's probably easier to create and fill in that ShaderVariantCollection than using IShaderPreprocessor

I have a small doubt.
We are building this city tycoon and right now the buildings have a shader that doesnt allow Transparency.
Whenever i want to make the 1 building transparent i replace the material for one that allows transparency.
Would be a problem to have the buildings always with the material that allows transparency? If so, which tool should I use to measure how much heavier it is?

#

this is an example of how the map looks and the buildigs look like. I did read when a shader allows transparency, even if its not transparent, the pipeline has to render the stuff beneath

tribal cipher
#

what kind of transparency? alpha blending or are you discarding fragments?

warm crescent
#

alpha blending

tribal cipher
#

oh, then you will have a lot of issues

#

overdraw is just one of them, but sorting will be the biggest issue by far

warm crescent
#

when you zoom in and collide with a building gets transparent

#

well it will be just 1 🤔

#

sincce i dont think the user can collapse with 2 buildings at the same time with the cam

tribal cipher
#

you'll likely be better off using dithered alpha fading in this case

#

but if it's only one building you'll be okay perf wise most likely, but there will be a visible pop when it switches to the alpha blended shader

#

while dithered alpha fading can be smooth (albeit without support for proper partial transparency)

warm crescent
#

but what would be the best option? change between materials? or keep the material that allows transparency and modify the _Alpha whenever I want?

#

or that doesnt matter ?

tribal cipher
#

if you have a transparent material on all buildings even when they're not faded, you'll run into lots of sorting issues

#

and overdraw

warm crescent
#

right now i exchange materials and works fine actually

#

aha

tribal cipher
#

swapping materials is totally fine

warm crescent
#

thats what I was aksing

#

I see, thats what i was fearing

#

okay ill keep replacing them

#

thanksa lot

tribal cipher
#

having the dithered fade on all buildings would still be fine though

main rune
#

@broken lichen You sir, are a fucking genius

tribal cipher
#

since they still write to the depth buffer

warm crescent
#

anyway, i dont know whats the dithered alpha fading 😅 ill look into ut

main rune
warm crescent
#

dithered

main rune
#

Working more or less as expected

warm crescent
#

does it belong to HDRP ?

main rune
#

Though it looks a bit squished

warm crescent
#

@tribal cipher , whats the difference between normal fading... 'modifying _Alpha value lerping its value' and dithered fading?

tribal cipher
#

alpha blending will disable writing to the depth buffer, which will cause all the overdraw issues, as well as the sorting issues mentioned earlier

#

dithered alpha blending is still an opaque shader, just like it was before, but you discard some fragments being rendered

#

the end result is that you don't have partial transparency in individual pixels, but on a macroscopic level it looks similar, if a bit pixelated

warm crescent
#

I see... well since theres not too many objects for the moment that will fade i guess ill be okay but i will keep in mind this dithered alpha bending

#

thanks a lot you have been very helpful

#

🙏

tribal cipher
#

example of dithered fading (make sure you open the pic 100% size)

8dd98d5de39679d6b69f8f6c9b05a0e8.png
#

so this can still be an opaque shader, with no sorting issues or overdraw involved

warm crescent
#

ooooh

#

smart

#

but i guess it cant go fully transparent then

tribal cipher
#

rip me trying to find info on this online and I only found my own old shader forge posts, haha

#

full transparency is very hard to get right without any popping or sorting problems in a case like this

warm crescent
#

I see

#

this might be cool for other effects like fog or smoke 🤔

tribal cipher
#

there are some advanced techniques you can use, like render the building to a separate render target and then fade that full render instead of trying to fade on the fly, but uh, that is a whole mess just for that one feature

broken lichen
tribal cipher
#

the whole building, fading when camera gets close

warm crescent
#

nooo, haha, the full building, when player zooms in too much and goes across the building

#

the windows so you can see people living inside 🤣

#

that would be nuts

broken lichen
#

Oh, yeah I've commonly seen dithering for that. I remember Human: Fall Flat did it.

warm crescent
#

thanks a lot, i got a bit smarter

main rune
#

I had a discussion regarding opaque transparent sorting a while back

tribal cipher
#

fix sorting how?

#

transparency sorting is like, still an unsolved problem in graphics~

main rune
#

Mixing and matching depth writing and sorting values IIRC. I got it to work pretty well. Have ship hulls which are opaque but in the transparent render queue surrounded by transparent shields with no sorting issues

#

I suppose 'fix' is the wrong term

tribal cipher
#

generally these are very special cases that have other artifacts

quick pelican
main rune
#

It's situational but worth trying to fiddle with imo

tribal cipher
#

it can be yeah

broken lichen
#

I personally think dithering looks nicer in this case

warm crescent
#

i didnt expect to look this good

#

5:09

tribal cipher
#

mind that you're watching this through the filter of video compression - in-game you will see the pixelation much more clearly

#

but yeah, this is pretty much industry standard for fading things like this

warm crescent
#

hmm, i see , im a bit of an analphabet on rendering stuff, never heard of

#

ill tell my partner to have it into accoun

#

thanks a lot

main rune
#

That does look very nice

broken lichen
tribal cipher
#

for water? oh no

warm crescent
#

do the problems you mentioned apply also when using the _Color property to blend between colors?

#

or thats not the same?

#

sorting, overdrawing.....

tribal cipher
#

it depends how that _Color property is used

#

blending between colors within the fragment shader is totally fine and has nothing to do with sorting/blending really

warm crescent
#

uhh okay 👍

tribal cipher
#

the issues arise specifically because:

  1. transparent shaders are order-dependent, which causes flickering/sorting issues, because the blend mode in the shader itself reads from the existing color/pixels "behind" what you're rendering (Blend SrcAlpha OneMinusSrcAlpha), so the order they render matters a lot in how it will look, unlike opaque shaders where the order doesn't cause a visual difference in this case
  2. transparent shaders don't write to the depth buffer, which is what opaque shaders use to not have sorting issues, so disabling that causes overdraw
#

and 3. enabling writing to the depth buffer in transparent shaders will instead cause other issues, because transparent shaders still read from the depth buffer, so other transparent objects will not struggle to render properly when they're in the same line of sight/overlap in screen space

warm crescent
#

thanks for the clarification. 👍

Hi! I started a new project with the HDRP template and was instructed to update. So I went to the package manage and hit update, and after about an hour of waiting (it was spinning my cursor like it was doing something), I finally got the following error. I closed and started a new project with the same template. Same thing, also after about an hour of waiting. No other package upgrades give me this error, only the HDRP one. I checked my firewall and disabled AdGuard after the first try, and got the same error again when I tried again with my firewall checked and AdGuard disabled. Here is the error (copied by hand):

Unable to add package [com.unity.render-pipelines.high-definition@7.5.3]: Cannot connect to 'download.packages.unity.com' (error code: ECONNRESET].

I have removed my old firewall rule (which had been set to Allow on Public networks) and created a new inbound/outbound rule pair by hand that allows absolutely all traffic, inbound and outbound, on all network types for this Unity version (Unity Editor 2019.4.20f1 LTS). I have just rebooted and will try the same steps as before on a new project.

#

Here's some additional information which may or may not be helpful while I wait for Unity to create the new project on my potato laptop:

  • I'm using the latest LTS, Unity Editor version 2019.4.20f1.
  • I use URP regularly, but haven't touched HDRP in over a year, so don't rule out it being user error.
  • I am working with fresh projects, created from the otherwise blank HDRP template.
  • Unity Hub and Unity are both installed in the standard location on my system root drive (C:\).
  • I am putting the projects on my external drive D:\ as I only have about 9 GB remaining on my system root drive.
  • My internal drive and external drive are both SSDs, and my laptop is a modern but low spec device.
    Unity is up now, I will try again.

can i somehow put that into a normal 3D project now?

No you can not, Shader Graph is URP/HDRP only

the edit stats say this

so, consider HDRP has the SRP batcher and what not, are the editor stats telling me anything useful these days?

i know lots of the profilers stats etc are for the old build in rendered and no longer produce proper numbers, but i also know that stuff is being worked on

okay, so change it to HDRP Lit standard (or unlit, if you like) then reselect the base map

#

thats not a standard shader which is why unity ignored it. not saying its a complex one, it litterely isnt the 'standard' shader that they use nowadays

no, really not 😛

bold robin

keen pivot
#

i've just walked down the road youre going down

#

i did exactly the same thing

#

and next you'll be re-doing all your lighting

#

THEN you'll be wondering why the hell your game runs so slow

#

but on the plus side, most of your materials will come back and using the standard is good

#

it also means when you try URP next you can easliy convert those too if they dont automatically work

#

but you can make things look really really nice in HDRP if you are targeting high end hardware

#

i'm, still using it but i really cant see me sticking with it once URP support deferred lights

#

also, if you dont have normal and mask maps on your lit materials, they likely wont look anywhere near nice enough to bother with HDRP anyway

#

best thing about HDRP for me is the lights look fantasic

#

legend has it the URP lights are still way better than the non SRP ones

damn

okay I only gotta fix this one but uh

isn't it impossible to convert this one over

bold robin

I convert like this?

keen pivot

i dont know as i dont know what the original shader does. its a custom shader not a standard one. you'll just need to experiment with that one i reckon

the diffuse one was easy as it was a basic diffuse shader

the speedtree shader is a URP one, you mentioned before you were using HDRP

your mileage may vary

I've been trying and failing to understand HDRP's eye shader. As soon as I apply it to my character's eyeball with similar topology and UVs to the demo mesh, it fails. What little information I could find in the documentation leads me to believe it's an issue with scale, something about the shader expecting an eyeball model that's 1 meter wide, which is obviously ridiculous. I can confirm this "1 meter wide" expectation is true as if I import my character with a scale factor to bring the eyeballs to that size, HDRP's eye material is now working, but that feels like such a filthy workaround. Is there a more proper way to correct the shader for eyeballs that are at a proper scale for a human character?

@waxen lantern would you consider yourself a good authority on being able to tell the capabilities of HDRP and URP visual fidelity. i.e could you identify from a screenshot or two, it something is beyond URP's ability to render?

@keen pivot is this a test? lol.

you can definitely tell the shading difference even on the workbench scenes... but does it matter for your artstyle? that's a totally another question

yeah post the screenshots already

HDRP is more featured, where URP is very bare bones.. but there are more 3rd party addons for URP to patch those missing feats

also... HDRP is way more perf heavy

performance is the main issue.. if you target PC games, it's not easy to make it scale well... or even for PC VR

then there are all kinds of lighting and shadow bugs you deal with tech that isn't fully matured yet

the problem i have in general is that the usual tricks dont seem to work

i have 2400 shadow casters and if i kill a few lights i get 600 and the frame rate doesnt really change

thats the other thing, i'm not working on an FPS, so while a 30fps....FPS ( 😛 )... migth work out on an xbox one, its seems hitting 60 is a big ask even for a simple project

I'm currently testing HDRP VR on Quest 2 via Oculus Link and it doesn't even run past 45 fps in the editor for me with scene that has mainly bunch of primitive meshes + scaled down HDRP settings 😄

#

it does get to 90 on actual build

keen pivot
#

thats fair the builds do run better

#

but like, the profiler just classes all the GPU stuff as 'other'

which is also seemed to so if you went DX12 on the old renderer

#

thing that puts me off URP is that it may be the fastest platform for 'now' but it cant last, i dont know about PS5/XSX yet but you can bet your rear end the PS6/Xbox series X two One X will handle HDRP just fine for everything

turbid matrix
#

@drifting vault I haven't really looked into details here but it's acting up pretty randomly on my testing... should spend more time with this to grasp why it's failing to keep up the target framerate at times (on exactly same project)

#

for example I had URP running fine on both editor and build with this same test project, then I put HDRP there and only kept up in actual build... then reverted back to urp and now it can't even keep up in build (or editor) anymore 😄

#

there's only really small details changed so I'm assuming now it's more of some leftovers breaking it (will try clean project again later on)

#

I am testing this with OpenXR plugin though, so that's another unknown here as it's still not fully released thing

thin phoenix
#

Here's hoping a proper solution comes soon though

#

I have to import my character as being in the range of 60m tall and scale them back down to get working eyes right now

Which means also making a new diffusion profile specifically for them, etc

Yeah I don't think that's true either. There are two basic approaches to AA as far as I know:

  • full screen postprocessing effects

neither of those approaches should care whether the boundary is actually geometry or just in the texture

MSAA indeed only works on triangle edges

so how would I solve my problem?

#

and setting anit-aliasing to 8 samples on a rendertexture, what does it do??

#

"When a RenderTexture is using anti-aliasing, then any rendering into it will happen into the multi-sampled texture, which will be "resolved" into a regular texture when switching to another render target. To the rest of the system only this "resolved" surface is visible."

waxen lantern
waxen lantern

some of the confusion here can come from documents that just assume you know references to regular plain old "anti-aliasing" is most likely MSAA.. because MSAA used to be the only anti-aliasing available from graphics APIs for real-time hw accelerated 3d rendering

pretty much following those mentioned steps 🙂

#

take away the sky settings from projects settings->HDRP default settings->default volume (you may need to create new default volume if you are on older HDRP as it used to use asset from HDRP package itself in past)

#

then do similar setup on some volume you put on scene and mark that volume's gameobject with some layer you can use to identify it

#

then just choose not to render that layer on the second camera (just remove that option from that camera object)

#

I guess one could also do it the other way and just make a custom volume for the second camera if you can override the sky to be none on the sky volume setup (never done it this way)

If anyone can help here. I am using URP. I have a cam pointed at the bucket pushing to a render texture. I am using that render texture on a quad (just to see the output). In the end I want to use an image of a group of objects on their own layer like the props here in the default scene. In the lower right it's saying this RT is 352mb. I can take a screenshot of the whole scene and it's 150kb. I need to keep the texture at 2048 to get the visual fidelity of what the cam sees, below that gets pixely. How do I take this rendertexture and spit out something that isn't bigger than the first hard drive I ever owned?

@primal spruce **render textures **are **uncompressed **and stored natively in gpu memory, that's why they are so fast and can be update every frame if need be. if you need the texture to update every frame you just have to put up with the uncompressed storage cost. --but if you don't need it to update and only need to "bake" it once or before scene load, you can store it in a **texture2d ** with **compression **as you only need to compress it once and decompress it once. this decompress is a slower process as it uses resources, but you can do it before the start of gameplay on scene load.

Where can I go to learn more about rendering hair in Unity HDRP? I'm having trouble understanding the workflow for hair cards. In Blender's Eevee renderer, it's as simple as setting my hair material to use "alpha hashed" transparency and it looks beautiful. It doesn't seem to be possible to replicate "alpha hashed transparency" in Unity from my research, so what do I do?

In URP, using overlay cameras, I am struggeling with accessing the "Scene Depth" (shader graph node) from a previous overlay camera pass. It seems the depth buffer is not copied over in between overlay camera passes. Can I force this somehow?
I've outlined the problem here: https://forum.unity.com/threads/feeding-depth-into-the-next-pass-camera-stack-or-render-objects-feature.1062848/ but I've also found an earlier thread by someone else that remains unanswered: https://forum.unity.com/threads/overlay-cameras-are-missing-copy-opaque-and-copy-depth-passes.1024555/

#

I have found 4 threads now describing similar issues, all of them unanswered. Is this perhaps a bug?

rich spade
#

I would not say it's a bug as such, I would not expect the depth buffer to cumulatively add camera's together. This is something one would need to tackle manually with a custom renderer in my opinion. As with multiple camera's which depth texture is active when it's read by shader graph is not guaranteed to be the one you expect. A custom renderer writing to a separate texture for depth, while needing a little re-write in the shader gets around this and gives consistent results.

tranquil saddle
#

Yea, I agree that it's not a bug per se, but I feel that, looking at the 'camera stack' as a feature, it doesn't make a lot of sense that only the depth of the base camera end up in the texture. Especially since the docs specifically mention that "At the start of its render loop, an Overlay Camera receives a depth buffer containing depth data from the previous Cameras in the Camera Stack."

primal spruce
#

@waxen lantern thanks for the info. I am looking to take a snapshot of a group of dynamic meshes in game and then have that image available for the rest of the game. The cam and rendertexture are acting like a real life camera only for one frame (i think). So if I go cam -> rendertexture -> texture2d is that the most efficient way to get an image? Would it matter if I save the texture2d to the file system for the duration of the game or if I just keep it in memory? I have found this way is giving me the alpha I need to only show the meshes, not the camera background. Thanks for your insight!

rich spade
tranquil saddle
rich spade
#

damn didn't think of that aspect, then your back to a render feature and manually stacking the output. Guess there's no simple way around it other than looking at why your using camera stacking and is there a better or alternative solution. Which you have probably already done and chosen camera stacking

tranquil saddle
#

Yea, I think a custom render feature for the depth copy is the way to go for now.
The reason I haven't been able to ditch the camera stack all-together is that I'm using a standardized Unity post processing stack in between two different passes, like so:

  1. render background things
  2. do post processing effects
  3. render more things
  4. do more final post processing
    I realize that instead of (2) I can make a custom render feature that does a full screen shader pass or something, but I explicitly want to use the post processing stack that I have defined in the editor. I haven't found a way to cleanly interject that in between.

Thanks for your input, @rich spade Draydak!

#

granted, the character is bald so at first i assumed it didn't use the hair shader

thin phoenix
#

Thanks for the assistance

#

I'm aware of this tutorial project and have already gone through it

#

Unfortunately it doesn't really translate to actual hair

waxen lantern
#

yeah i couldn't find any samples or tutorials of full heads of hair either

thin phoenix
#

My main trouble is alpha sorting

#

The hair cards I have are so dense that Unity doesn't know what to do I guess

#

This is why I draw the parallel to Blender

#

This so called "alpha hashed transparency" method automatically solves sorting issues, and with the immense popularity of both Blender and Unity it's surprised me greatly that I haven't been able to find information on this so far

waxen lantern
#

well i know of examples of hair rendering with VFX graph which does all the sorting on the GPU

thin phoenix
#

Would you be able to dig those up?

#

If it's VFX graph I assume it's particle systems though, wouldn't it be? Simulating hair strand by strand kind of like NVIDIA's Hairworks solution.

#

I'd have to completely rebuild my hair I would think

waxen lantern
#

@thin phoenix the vfx graph tutorial that peeweek released on youtube is individual strands of hair, yeah. though it could be cards / quads, quad strips

thin phoenix
#

I'm sorry, peeweek?

waxen lantern
#

peeweek = thomas iché. he works for unity on the vfx graph team in paris

thin phoenix
#

Ah, that would be why I wasn't finding him

#

Interestingly I got results for a channel also called "peeweek VFX" that was inactive and seemed incredibly amateurish lol

waxen lantern
#

ahh lol

#

maybe his early days?

thin phoenix
#

You say VFX graph could take cards though? Where can I learn about that?

waxen lantern
#

@thin phoenix well this tutorial is already using particle quad strips, just 1 strip per hair. you could adjust by making the quad strip wider and texture mapping it with multiple hairs per strip instead of just one per strip

thin phoenix
#

Ah, but I would still have to groom from the ground up

#

I couldn't use my existing quad strips

waxen lantern
#

or if it's short hair just output particle quads instead of quad strips

waxen lantern
#

it goes pretty deep in what you can do with it

#

it might require some custom property binder and or point cache baking to really integrate a groomed hair attribute content pipeline for vfx graph, though

thin phoenix
#

Hm, alright. I'll have to see what I can dig up I guess.

waxen lantern
#

@thin phoenix your other option is to find or write a sorting method for your existing system.

thin phoenix
#

My existing system is just the mesh imported from Blender with HDRP's Lit shader

#

I'm definitely a Unity beginner

#

HDRP's Hair shader produces even worse results with this particular mesh

waxen lantern
#

so it's expected that using alpha channel on hair cards will look bad without sorting, sadly

thin phoenix
#

I'm kind of back and forth between two engines right now. I've been essentially doing my entire project in both Unity and UE4 synchronously

#

UE4 does a far greater job at this hair stuff with a process that took me 2 minutes to do even as a beginner, it's a shame Unity is behind in this regard

waxen lantern
#

yeah unity is a behind in this regard i agree

#

vfx graph is the best bet i'd say i know work was or is being done to make it integrate with the hair shader

thin phoenix
#

I'm definitely not a fan of Unity's use of a so called "mask map"

#

I understand texture packing is good for shipping where optimized file compression and memory usage matters, but when the project is in its earliest stages where there's loads of iteration going on, having to pack my PBR textures into a "mask map" is really slowing me down

#

UE4 just takes my PBR maps as is

waxen lantern
#

@thin phoenix yeah i hear you... it should be part of the import process by default. and optionally you could (on import) select that you pre-channel-packed your texture data

#

in some ways i think unity casts such a wide net to do "all the things" but it ends up being a much slower process to be making a product that does everything for everyone vs epic who focuses unreal engine on a certain segment of the market and a limited number of use cases and just doing that really well. then, whatever unity is behind on in those, it relies on its vast community to try and fill the gaps until they can catch up in that area.

#

again it still 100% should be built into unity :P

thin phoenix
#

Ye I'm using one already

#

Just an annoying step

#

Very much a first world problem haha

#

It appears that I can get around it by creating my own shader graphs

waxen lantern
#

conversely unreal engine is really excellent if you fit into their target market / use cases, the workflows are amazing and rapid as you found with their hair tools. but then if you need something outside of the use cases that epic focuses unreal on, the community isn't quite as vast as unity's and the asset store for unreal is quite lacking. so it can be more of a challenge to find resources at times and for unique use cases.

#

so, by all means i recommend unreal for projects and teams that it happens to fit well for

#

for everything else.. there's unity™

thin phoenix
#

Sounds about right

waxen lantern
#

@thin phoenix i also encourage you to check out the graphics roadmap to see what's currently in development and what's planned or under consideration. you'll see there are 4 items about hair features on the HDRP roadmap. you can submit feedback to the graphics teams here by selecting one of those items and then selecting an option for "how important is this to you." a text input field will appear and you can explain your use case and/or tell them what blender eevee and unreal do that you'd like to see in unity, etc : https://portal.productboard.com/unity/1-unity-graphics/tabs/18-high-definition-render-pipeline

Hi, I would like to know if their is a way to "render the shadow" on another Camera using the 2D Renderer (URP). I would like to make the shadow rendered with a low resolution (using the Pixel Perfect component) while not using it for everything else in the scene

waxen lantern
# whole fossil hah, thanks! I strongly disagree with `Visually is pretty much identical before/...

i dealt with this as well and was able to get back to the desired quality. afaik this is something to do with the way quality settings profiles apply to volumetric lighting now instead of being limited to explicitly adjusting the volumetric fog override properties. the quality settings can be adjusted to look how you expect it's just that the properties have been reworked to be more implicit and flexible by default in a way that doesn't directly translate to the previously explicit / manual only properties .
or as pierred_unity at unity said in the forum thread @turbid matrix linked above

Using the new Balance mode is a lot easier, you just set the cost, and then the ratio, and it will maintain the cost constant. The previous Manual method was very tedious when trying to maintain the cost, as it was nearly impossible to tune the XY quality and Z quality easily.

#

granted it was frustrating to figure out what changed in the settings and defaults and adjust to this, but visually it can be identical. it just took some time to get familiar with the new quality settings / properties. i found that creating a new HDRP template project and using those quality settings as reference for what to set in my own project was helpful as well.

# lofty plinth Hey guys, I am a complete beginner and midway through the project I found out th...

That's the nature of the beast. only so much can be automatically converted. Any materials with custom shaders have to be manually upgraded by hand / in code. Here are the material shaders that are auto upgraded. if it's not on list it's considered a "custom" shader and needs to be manually upgraded. if it's from an asset you purchased you can check if the asset publisher has already done so and has URP shaders available: https://docs.unity3d.com/Packages/com.unity.render-pipelines.universal@10.3/manual/upgrading-your-shaders.html

there are other improvements like with lighting that doesn't directly translate to how built-in RP works and need to be manually adjusted.

@lofty plinth hmm the lights shouldn't be destroyed, but their properties likely need to be adjusted as the way lighting works was fundamentally changed.

render pipeline migration is no small task unfortunately unless you were only ever using unity default materials / shaders.
the render pipeline is more of less one half of the entire engine. you're keeping the back end of the engine that manages behavior, logic, physics and replacing the entire front end of the engine. not much is directly compatible with the old Built-in RP... or if it had been Unity would have kept tacking band aids on to the Built-in RP but it was too "long in the tooth" to keep tacking features onto.. so they had to start over.

#

so in a way the difficulty of migration is similar to porting your game to another engine... but limited in how it appears not how it functions

dawn sorrel
#

ok uhm... uh... uhm.. Why are my legacy / mobile diffuse shaders all purple. What do i actually have to do to let URP work with it, all i literally need is realtime SSAO or AO.

waxen lantern
#

@dawn sorrel what i told @lofty plinth here is the most i can assist with this unfortunately. it's not easy in most cases: #archived-hdrp message

lofty plinth
#

Damn thank you so much @waxen lantern still, I am definitely noting it down had no idea how it works. Beginner mistakes starting without it

waxen lantern
#

@lofty plinth oh no worries i mean Unity advertises all the improvements for these new render pipelines and it's tempting to migrate your entire project but it's a large undertaking that may require significant graphics programming knowledge especially if there are non- default shaders involved which is very common. But honestly for many projects and teams... unless they have the resources for a render pipeline migration, they are better off sticking with Built-RP for their current project, but consider URP or HDRP when starting fresh for new projects.

dawn sorrel
#

ill follow the 'upgrade your shaders documentation' i guess

waxen lantern
#

similar to how changing engines mid project would be a major undertaking.. this is roughly 1/2 of that effort for the countless projects with custom shader and rendering code.

#

it's possible by all means but if you're not sure you have the time/resources to migrate to a new RP for the size of your project, i'd hold off or revert to your last backup and stick with built-in RP.

@dawn sorrel Sure thing. the items i circled should get you on the right track if you decide to stick with 2019.4 and Built-in RP.

Hey all, making a postpro effect on URP, and it seems as though the URP (or maybe it's 2020.2) editor window just rolls the dice on where it puts inspector variables, literally randomizing the order they go in (not alphabetical, not how they are listed in code).

alpine zodiac

I installed URP but it won't let me select it as a rendering pipeline in my project settings

read "Getting started"

basically you are missing URP asset because you either haven't created one or your template didn't provides you one

alpine zodiac

I installed it from the package manager, and i didn't start the project in URP

Luckily, there's not toooo many shaders/materials in it

you can convert or config it from scratch too even if you don't start with URP template

alpine zodiac
#

I've actually done this before, but i went back because franky it scared me with how new it was

turbid matrix
#

but docs should cover the steps

#

either way, your current project simply doesn't have URP asset to assign, URP package doesn't provide you one, it has to be on your project itself

If I want to create a game with very good graphics, but also VR support, would it be better if I choose HDRP for its graphics or is URP also sufficient for creating great graphics? URP has better performance, which is important for VR, but I'm not sure about the graphics quality you can create with URP

broken lichen
#

@thorn hollow Could you name some examples of other VR games with the type of graphic quality you want to achieve?

thorn hollow
broken lichen
#

Some things from Alyx will require some work to achieve in URP, such as volumetric lighting.

#

But I personally would never consider using HDRP for a VR game, because of the performance overhead.

#

I'd say Alyx render pipeline is closer to URP. Forward renderer, MSAA

thorn hollow
#

would it be possible to achieve stunning graphics in urp? I hear everyone saying it's for mobile devices, etc

broken lichen
#

It's absolutely possible, especially if you can bake most of the lighting

#

Alyx's stunning lighting is thanks to most of it being baked

thorn hollow
#

but what if I want to have a lot of non static lights like torches which can be lit/unlit?

broken lichen
#

Can you throw out an estimate of how many lights you'd need?

thorn hollow

maybe 50 per scene

broken lichen

Do you have any reference image for what this would look like so I can get a better idea? Preferably from another game, not necessarily VR.

And you'd like for all of these to be dynamic? So they can be turned off and moved?

thorn hollow
#

exactly

broken lichen
#

Assuming the cave walls are mostly one mesh, that will not be possible in URP because URP has a limit of 8 realtime lights per object/mesh.

#

That is, until the deferred renderer is available in URP

Which I think maybe it is already?

This lighting definitely looks like it fits better with deferred. I can't see that you can bake much of this.

#

But there are times where you have to sacrifice some of your vision to be more realistically achievable.

#

How important is it really that you can turn these lights off?

#

Are they meant to be placed by the user?

thorn hollow
#

It was meant to be a main feature, but I can rethink that decision

broken lichen
#

A game where the main feature is to turn lamps on and off?

thorn hollow
#

That’s not what i mean lol

#

Like when something happens in the environment all lights turn off

broken lichen
#

Oh well that's a little different.

thorn hollow
#

They don’t have to be movable

broken lichen
#

If you don't need to be able to control each light individually, you can do some tricks like swapping out lightmaps when they are supposed to turn off.

thorn hollow
#

And if they do have to go individually in an order?

broken lichen
#

That's more difficult

#

If you go with HDRP and make it fully dynamic, you're paying a high cost to avoid needing to do tricks like this.

#

But almost no AAA game has no baked lighting. It's just not possible to achieve that photorealistic lighting without baking it.

thorn hollow
#

Okay so if I’m understanding this correctly, I should either; - use hdrp and reduce the overall graphics to keep performance or - go with urp and bake lighting in a tricky way

#

If I want vr support*

#

Or just remove the dynamic lighting feature and go with urp

broken lichen
#

Oh, deferred rendering is apparently not supported in VR with HDRP

#

Not volumetrics either

thorn hollow
#

Which is important for vr?

broken lichen
#

No, most VR games are not using deferred rendering. But deferred rendering allows for many more realtime lights compared to forward.

thorn hollow
#

So neither urp or hdrp support deferred lighting for vr

broken lichen
#

Doesn't appear so. But most VR games use forward rendering anyway.

#

IF it's a must have I'd be tempted to go with what MentallyStable said about breaking up the tunnel, I imagine 8 lights could go a fair distance and some creativity around any seems would hide any overlap.

broken lichen
#

Baked lighting in a tunnel like that would look soo much better though, because you're going to get all that global illumination bouncing around.

rich spade
#

true

#

unless you can fake it though, there has to be some sacrifices in VR

broken lichen
#

And you could fake some light flickering with a custom shader on the tunnel surface

thorn hollow
broken lichen
#

I'd say regardless of which pipeline you choose, baking the lighting will always ensure the highest quality. If that is your goal, then you should be able to achieve that in URP as well as HDRP.

thorn hollow
#

As for hdrp, I’m sure you can reduce the graphics to match urp performance, right?

broken lichen
#

No, highly unlikely

#

If that were possible, there would be no reason for URP to exist

thorn hollow
#

Aww man never thought this would be such a tough choice, haha

broken lichen
#

I'd say go with URP.

#

I've never considered HDRP a realistic choice for a VR application and I've yet to see someone use it outside of enterprise use-cases.

thorn hollow
#

Do you know any games which use urp?

broken lichen
#

Not off the top of my head. It's still so recent that it wasn't an option for developers of the games that are out today.

thorn hollow
#

Okay thank you for this conversation, I’ll most likely port my game from hdrp to urp soon

turbid matrix
#

most of HDRP functionality works in VR too, including volumetrics (afaik anyway)

#

it's another thing which are actually feasible to use in VR perf wise

#

HDRP itself is notably slower

#

(than URP or built-in in VR)

#

@thorn hollow but yeah, pick URP or built-in for VR and you will be having a better time

#

that being said, there are perf issues atm on URP with 2020.2+ (on both desktop and VR, Unity is investigating it)

broken lichen
turbid matrix
#

yeah, google tends to do that :/

#

at least nowadays it suggests new enough pages to have that version dropdown so you can manually swap to recent release..

thorn hollow
#

that being said, how do I easily convert my hdrp project to urp?

turbid matrix
#

need to manually swap the shaders for your materials, unless you script it (or if you only use shader graphs, you can just swap the SG targets on the URP / HDRP 10)

waxen lantern
# thorn hollow So neither urp or hdrp support deferred lighting for vr

HDRP does support Deferred in VR

Here’s a very quick overview of the features available for your VR projects: Deferred and Forward rendering...
but like @broken lichen was saying, most VR projects still use Forward as the performance overhead of Deferred in VR is very high. And because you need Forward for MSAA which looks better in VR than other AA. aside from SSAA (super sampled) which is extremely expensive on performance . https://blogs.unity3d.com/2020/03/12/creating-immersive-photorealistic-vr-experiences-with-the-high-definition-render-pipeline/
this article is a bit older too when HDRP hit verified release. But safe to assume that that the feature support is at least what is described here.

Hey @turbid matrix, could you help me understand something with documentation?

waxen lantern
#

@viscid solstice you can disable volume rendering features like fog or volumetrics altogether in frame settings. but you can't override / change the current camera's volume from one volume profile to another volume profile in frame settings.

#

(i'm not exactly sure which you are asking about.)

@thorn hollow sounds good. yeah URP seems like the best bet for mass market VR at least for this era anyway.

Good night everyone, did anybody face editor issues with a plain empty hdrp scene taking up 100% cpu usage?
I've spent all of yesterday's (friday) night and today's evening trying to understand why the Volvo HDRP Sample didn't "work" on my 2020.2.0f1 - 16GB - 1660ti - win10 PC. Guess what? Dx11 to blame! Changed to Vulkan API and Presto! Smooth as silk! 😄

#

Now, the real question: are we still going to wait much longer for anything like hdrp for android? 🙂

the next generation (or gen after next gen, etc) of mobile hardware with sufficient API support and compute power increase on an order of magnitude must come before software support for HDRP can be delivered. mobile GPU vendors like Imagination / PowerVR are working on it. As is Qualcomm, Apple, Samsung, etc. The ball is in the vendors' court right now, so to speak : https://www.imaginationtech.com/blog/the-unity-high-definition-render-pipeline-powervr-meetup/

In regards to FrameRender Settings, does anyone know how to modify cameraSettings.renderingPathCustomFrameSettingsOverrideMask.mask[(int)FrameSettingsField.MaterialQualityLevel] = true; on a per level basis?

viscid solstice

I understand this allows us to access the ability to set custom frame settings

but how does one access the ablity to SET them after enabling them?

I use this for some basics initially, good version to get you started which does not have lighting is https://github.com/ColinLeung-NiloCat/UnityURPUnlitScreenSpaceDecalShader
For a shader graph version, which you can then add lighting and shadows too etc. I started with https://github.com/Harry-Heath/URP-Decal-Node
but I modified it slightly for better clipping and then built on that.

I'm looking for some advice

#

I am developing for VR usinng steamVR.

#

I need to have realistic graphics, I tried using hdrp + vr but it caused problems with steamVR

#

Any suggestions?

turbid matrix
#

hdrp + vr is going to be super demanding combo

#

it should work with steamvr though

elfin aurora
#

@turbid matrix I'm trying the regular URP righ tnow

#

The steamVR default controllers show pink, but other than that this seems enough for my project

Well.

#

The pipeline is universal, unless im doing something worng

#

*wrong

#

but it's saying it's using hdrp's building thingy?

#

I don't know the technical terms :/

#

Don't you love it when you send something to get help, then realize what the problem was

turbid matrix
#

TL:DR: Enlighten will be supported on 2021.2+ URP and HDRP, until Unity 2024 LTS ends

#

so... I guess they brought it back for 3 more years since they haven't come up with their own GI solution yet

#

I was hoping to hear more about that but blog post didn't mention anything but saying it's not happening on 2021 cycle

#

just to make sure URP does not have a layered shader like HDRP right ?

#

I want to make sure before I go ahead and make one

scarlet hull
#

It doesn't

If you're going to make yourself a layered shader for URP, I'd suggest that you take a look to this if it's not already done 🙂

You can improve the runtime efficiency of your shader without sacrificing the quality of your graphics by packing physically based rendering (PBR) material information into a single texture map and layering it into a compact shader. Check out this experiment.

First time using HDRP, I'm trying to add this to an existing project so that I can work on some shadergraphs and it's broken a lot of my pre existing textures , ive upgraded project mats, scene mats, terrian mats etc to HDRP, and yet I still have a tonnnnn of purple mats. Is there a way to cleanly import HDRP? I've tried everything available in the HDRP wizard

@scarlet hull i have been looking at this for a couple of days. Do you think it's applicable for a floor in a VR game ? I think it might be.

It's not standalone VR but we still have a rather dense scene with lots of objects. Right now we have it down to 7ms on the index resolution. I might try moving the entire environment to this type of shader. We are already atlasing everything so it will be interesting if we get a perf boost out of it

Hi. I'm using HDRP and I saw in some level design video someone using a huge projector with some wet/rain shader over the ground.
How bad is projector performance in HDRP if you put it over whole map?

My other options are smaller projectors for decals (there would be hundreds of them though) or maybe using compute shader to write to terrain splat or make custom terrain shader.

uneven roost
#

Are they custom shaders @rich tide ?

#

Unity will only convert the standard shaders over to HDRP

https://github.com/Unity-Technologies/Graphics/pull/3747:
This PR Adds a new control mode for ray traced reflections and ray traced global illumination. This new mode combines both ray marching and ray tracing to solve visibility. This allows for both potiential peformance boost and access to details that cannot be stored in the RTAS (Decals or opaque particles). The option can be found on both volumes and are only comptaible with the performance mode.

You even copy paste my typos

turbid matrix
#

wouldn't be a quote otherwise 🤔

heavy ice
#

Eh, sure whynot

#

😄

turbid matrix
#

I still haven't tested this, is there notable difference when you go from SSR to RTR on the reflected surface?

heavy ice
#

Slight artifacts, but nothing major really

turbid matrix
#

pretty sure it looked quite different color wise when just toggling SSR and RTR itself

heavy ice
#

What i mean is you won't get much of a difference going from Ray Tracing To Hybrid

#

Hybrid is not SSR

#

SSR is its own thing

turbid matrix
#

oh? I thought it used SSR for parts that existed SS, my bad 🙂

heavy ice
#

Nupe, different implementation for many reasons

#

anyway give it a try and send some feedback if you find stuff not working good for your usecases

turbid matrix
#

does the hybrid work with vertex offset in shaders or is that still out of the question?

#

(yes I ask a lot about that)

heavy ice
#

yes it works with it

#

you'll see vertex displacement if it is on screen

turbid matrix
#

I'll try to give it ago tomorrow 🙂 this probably doesn't require engine side changes so it runs on 2021.2 alphas?

nah
