[lone river]

hey guys can some one help me out firuge the cause of this error?
these trees are doing this is build mode

in another scene this does not happen

[summer glacier]

Random question, tempted to report it as a bug but I'd like a confirmation first:

Reprojection denoising in volumetric fog increases performance cost by 2.5x-3x

Is that expected or should I report it as a bug?

[scarlet hull]

I'm not so much surprised that reprojection denoising increases the cost.
I think it increases by a more or less fixed value depending on there voxel resolution

[digital spire]

Ty for the tip: do not enable reprojection denoising in volumetric fog.

[summer glacier]

It's just surprising how big of an increase it is. At medium quality it's about 1.5x to 2.5x
your probably right increase is based on voxel, sometimes it's 1.5x increase, but can go up to 2.5 depending on the settings
The bummer is that reprojection denoising really helps static lights/quality, even at low quality it can make volumetric fog look good.

I guess it's not reportable than 😄

There's another issue: When the post process "fog" is enabled, but inside it you disable the fog like this pictue:

The volumetric fog cost will actually still happen as long as volumetric fog is ticked, as if volumetric fog is enabled, even though there's no fog/volumetric fog on screen. Even if this is working as intended, it doesn't make sense (unless there's a point to it I don't know about), volumetric fog should rely on fog being enabled

[summer glacier]

Yeah reprojection is very expensive (1.5x/2.5x), but.. it really pushes visuals for your volumetric light.
edit: then again, you can push volumetric fog quality quite a bit if you use gaussian denoising until you reach the cost it would be on lower settings with reprojection, so I guess it really depends on your particular project
reprojection is also better when you're moving next to punctual sources of volumetric light

[junior thicket]

i'm not sure if this is the place to ask it but
me and my friend are trying to make a see-through texture, like a fence with the see-through holes in it
we have literally no idea how to do that and whatever we try doesn't work
it's transparent in blender but not in unity
could anyone please help us with this?

[junior thicket]

i'm not sure if it's even using all the texture maps that i imported it with

i don't think it is

is there a way to know that?

[junior thicket]

we have literally no idea how to make the model use all the texture maps

[steel meteor]

Your texture should have an alpha channel unity will the use to cut holes in it. It can be done without an alpha channel too but the results aren’t generally as good.

If you select your texture in unity you should see the texture properties window. In there check the alpha settings to see if they been enabled.

[shrewd moon]

Materials define how textures are displayed on meshes, alpha clipping and transparency included

Just a warning that HDRP and the resources for it will assume that you have a solid grasp on rendering fundamentals like these, so it's a really rough choice to start out with

[steel meteor]

It looks like your bloom level is too high.

In the your GameObject Hierarchy, select your Global Volume and then in the inspector find the Bloom override and disable it to see if that makes it any better:

If you can temporaily disable it just to see if that is what's causing the blow-out of your materials, that would be good.

[summer glacier]

it's exposure

go to exposure, set it to fixed, and change value until it looks right

look up exposure in HDRP doc to learn more about it and how to use it correctly

also check global settings, HDRP has a bunch of post processing by default enabled. so when you disable ur stuff in the global volume, it might fallback to bloom from global settings

[steel meteor]

Yes, HDRP tries to render scenes based on the real world properties of light and materials etc. So the expose might be too high for your camera and you get an 'over exposed' picture.

It'll be one of things that you'll need fiddle with and try to understand what all the different properties do.

Change the fixed expose value until it looks better.

If you have a day/night cycle then you can't use a fixed exposure. You'll need to use dynamic, so change the mode.

[summer glacier]

reflection probe

[steel meteor]

All of those are dynamic, it just depends what the best one to use is. Automatic is the easiest, but not always the best results.

Again, best to just play with the different settings

[hidden plank]

What's the recommended way of having per render parameters for a HDRP shader graph material? Like if i have fish swimming around with various velocity and want to control speed of my vertex shader waving?

[exotic fable]

Hi, my game is super blurry in the middle of the screen. Any idea why? Is this some HDRP setting?

There is no bluriness in the editor

[mellow condor]

is there a way to ensure a screen space - overlay canvas appears in an hdrp camera render to render texture?

[mellow condor]

i think you probably have motion blur or depth of field turned on. try turning it off

[mellow condor]

control speed of my vertex shader waving
expose a property in your graph, and modify the material

[upbeat hill]

I'm having a really strange issue. I've booted up a brand new, totally fresh project with the 2022 Unity Build, in HDRP, and there's these weird black artifacts on my model that I imported, (That are being cased by something in the shadows, I've almost certainly narrowed it down to)

I don't know what EXACTLY is causing this though, or how to fix it. Can anyone help here? I'm sorry if this is an inept question.

I have not done ANYTHING to this fresh project other than add a model and a floor to it, and there are no special materials or shaders active.

https://cdn.discordapp.com/attachments/497872424281440267/1001307723134152724/unknown.png

Turning off shadows fixes it, but well, it turns off shadows.

[hidden plank]

No I don't think so. Hundreds of fish with different materials is completely unoptimizable for the renderer. Is must be something like material property blocks or something.

[scarlet hull]

Looks like contact shadows

[shrewd moon]

The particle system has custom vertex streams feature which can do that very efficiently
You might be able to implement something like that yourself, though it might be smart to use the particle system for flocks of fish

I would expect VFX graph has something similar

Material property blocks are probably the next option but it won't work with SRP batching

[hidden plank]

Ooh, this is very interesting! Tried out the vfx graph yesterday, will look into it for fish!

[shrewd moon]

I'm not totally sure what the artifacts are in this picture, but if you mean the grainy shadows that looks like shadow filtering

How much half-shadow there is that needs to be filtered depends on the light source diameter; smaller diameter means sharper shadows
I've heard that lowering the filtering quality to medium makes them less grainy

[eternal laurel]

Just a heads up if you have any form of flocking behaviour (boids) you will have to do that sim in a seperate compute shader and pass that data into the graph via the rather new compute buffer access.

[mellow condor]

change your shadow filtering quality to Low. then yes, turn off contact shadows

you might also have to adjust the cascades. it's hard to tell from the scale of your model

[ionic flame]

im using hdrp and have emmissive lighting

basically my problem is you see the bars next to the light are really absorbing the light and i dont want that

but i still want to maintain the base color

[steel meteor]

I’m not sure what you mean by ‘bars’. I can light coming out between the gaps in your tiles though, is that what your talking about?

[ionic flame]

oh no those arent gaps

ill change the lighting so you can see it better

i just made it green

[steel meteor]

Ok, I see what you mean. Are you using a point or area light, or just baking with emissive light?

[ionic flame]

im using emissive

[steel meteor]

And baking?

[ionic flame]

yeah

[steel meteor]

So the colours on the bars are correct because of bounce lighting, you just don’t want them to receive any light.

You could untick the static checkbox for the bars so they aren’t included in the baking process. That’s one way.

[ionic flame]

i dont want them to recieve no light just significantly less

[steel meteor]

Hmm. I’m not on my pc at the moment. I can’t check to see what other options are available.

[exotic fable]

Thanks man, it was motion blur, but was hidden deep down in an HDRP file

[indigo summit]

can someone remind me what is this thing called? i totally forgot the name

[scarlet hull]

The rendering debugger ?

[indigo summit]

oh that what is it called, also why is the default tab are on decals though? not display stats?

[scarlet hull]

It reflects the tabs order from the editor version (window/analysis/rendering debugger), I guess they are ordered by name

[indigo summit]

oh i see

[scarlet hull]

But indeed, having display stats as the first one would make sense

[indigo summit]

last question, the mini render stats (right side), if i want to close it i have to tab the shift button 3 time, is this intended?

Ah when not in play mode the display stats are not available (which kinda make sense)

[scarlet hull]

I don't think so 🤔

Feel free to report a bug for this one 🙂

[indigo summit]

will do then

let me check using the latest beta

[indigo summit]

Oh wait i think it's intended, each time i press shift it toggle the mode from avg,min,max and close the window

so yeah, nvm then 😄

[eternal laurel]

wait wait are the hair samples out ?

cause I checket the beta yesterday

and did not find the samples

unless they are in the material samples

[hollow frigate]

does anyone know what version reflection probe time slicing was added? I'm on 2022.1 and I can modify the value in script, but it doesn't seem to affect anything

[indigo summit]

i think it's inside the material samples

[indigo summit]

is there a way to modify custom pass properties from other script?

[indigo summit]

hmm i have to work it backward it seems if i want to modify custom pass properties from other script, by making the custom pass to copy other script properties instead

kinda weird but it works

[upbeat hill]

I have contact shadows turned off, and messing with cascades doesn't seem to affect it. I also can't seem to find any options for Shadow Filtering, it's not under the Shadows tab in project settings, and it isn't in the shadows tab for the light source I'm using either.

And here's another pic of the problem in question. It seems to only happen in places where the model I have is in its own shadow? The normal cast shadows by things aren't affected?

Oh, nevermind, I found it. It wasn't under the HDRP settings, it was under the Quality Settings. Sorry for the trouble.

[shrewd moon]

@upbeat hill Did you change the light's diameter yet

[upbeat hill]

The only light in my scene is a Sun, I can see if that has a diameter, but I didn't think it did?

[granite marsh]

Hello guys

I would like to know, if there is a way to render transparent particle (like a smoke particle flipbook) inside a mesh with a hdrp transparent refractive material? Any clue ?

[scarlet hull]

If you render it in the "before refraction" render pass it should work

[granite marsh]

@scarlet hull i've tried, but i get nothi,g :/

[scarlet hull]

Oh ...
I remember there was a bug about this, but I was sure that it has been fixed 🤔

[granite marsh]

😢

i'm on hdrp 12.1.6 btw.
i've 2 refractives materials for the tank + liquid, then the smoke flipbook.

screen for the flipbook.material.
Hdrp is new to me :/
A lot of parameters to tweak.

[scarlet hull]

Wait, are you using the legacy particle system or VFX graph ?

[granite marsh]

legacy particle system

[scarlet hull]

I'd recommand switching to vfx graph, the legacy particle system is not really made for HDRP

[granite marsh]

Ok, i'll give it a try 🙂

[quiet quest]

anyone ever had HDRP drawn nothing no girds no cubes nothing

no errors

wizard is green

i dont know what to do here

[scarlet hull]

This should not happen, but sometimes can be fixed by:

• changing scene
• creating a new scene
• entering play mode
• reopening the editor
• nuking the library folder

[quiet quest]

seem like nothing works...

ummm

not sure what I can do here

[scarlet hull]

This is ... unexpected.
Does it also happened for a newly created project with HDRP template ?

[quiet quest]

no it does not

[scarlet hull]

So it does only happen to you on existing projects after importing HDRP ??

[quiet quest]

it looks like from a custom template

i will have to dig some more

but let me ask a qustion

will HDRP break if you create a new proj w a different name and copy in the ProjectSetting, manifes.json and asset ?

from a working project

isnt that essentially what a template is?

[scarlet hull]

It might, for example the HDRP assets assigned to the quality level will probably not have the same GUID and will be lost

Ah no, if you copy the assets with it, it should work

[quiet quest]

ill do a small test, i have a feeling this is what happed here

thats Remy for the help

thanks*

[mellow condor]

it's in the quality > hdrp section. it's your shadow filter. try turning it to low.

[mellow condor]

why does the color in the swatch look nothing like the color i've chosen

this is ridiculous

why is it saving the wrong color

does anyone use unity for anything anymore?!

how am i supposed to use

a color in two places

this is so ridiculous

whatever

[shrewd moon]

HDR colors do not appear like their previews because they're emissive and subject to exposure, but I can confirm that they are saving and loading correctly from swatches

Trying to save a HDR color as a swatch and then using it as non-HDR will cause a bit of mismatch as well

To be fair it'd be kind of complicated and ultimately pointless for the UI to try to adapt to different color field types

Because colors aren't one to one convertible between HDR and LDR anyway

[lament comet]

Hi guys! Is possibile to connect mobile controller (like iPhone or iPad) for a pc game with HDRP? Thanks you 🙏🏼

[shrewd moon]

Sounds more like a coding question
Input devices don't care what render pipeline is in use

[lament comet]

thank you! would you have some guide to follow?

[lament comet]

because what I found make me switch to mobile game

[undone pecan]

question:
does anyone have any experience with textmesh Pro and HDRP?
Its not working with the materials, and its just blurry.

[upbeat hill]

I'm in version 2022.2, and I'm having trouble getting a camera to render out alpha into a render texture, I've tried setting the Color Format to different things like suggested, but I don't think it's working at all.

(It should only be rendering the character in the middle, but for some reason, it's writing weird stuff underneath them)

i'm basically just trying to set up a pixel perfect outline around entities in my scene.

[upbeat hill]

OK, nevermind, now I have a different problem. I'm having trouble figuring out how to get Scene Depth into my Custom Pass to work. I'm pretty sure it's not working, right now, I'm trying to pass the scene depth to the screen so I can visualize it, but it's only outputting pure white.

I read that this node setup is supposed to do that, but it's not working.

[upbeat hill]

I seriously can't figure out how to get my custom pass to actually generate the depth I need

[upbeat hill]

Ok, so, I've written a script that I read would make the camera go into depth mode, but it STILL only outputs full color to the buffer render texture I have assigned to it.

[upbeat hill]

Ok, so, it was working before, but now when I plug HD Scene Depth directly into my fullscreen shader, it just renders this black triangle over half of the screen, and I'm not sure why.

Does anyone know some possible reasons why this might be happening?

[upbeat hill]

Nevermind. I've managed to figure out all of this stuff myself after some trial and error.

[ionic tangle]

What happened to this Fog parameter ?

or how do one have sunshafts with volumetric fog & clouds?
I'm reading that i'ts only two options but nothing works when I do it.
I always end-up downloading a package from a forum that do work and I can't find the differences in parameters.

ehhhr okay that's here, but it does nothing either.

[ionic tangle]

Hm

[barren goblet]

how to use DrawProcedural in custom pass?

[idle sage]

hello, can my GTX 1080 support ray tracing in Unity for HDRP?

I have researched and it seems that "yes"

because it uses something called "ray tracing fallback"

[loud leaf]

Yes it should, if you have the correct windows version + nvidia driver. Keep in mind it will be pretty slow.

[idle sage]

ok thanks! yes probably it will run pretty slow..

[rugged kernel]

Is there any way for me to cast shadows with a area light without the object being static? I want it so when a door opens the light from the other side leaks into the room your in

[steel meteor]

I just tried an area light on Unity 2022 HDRP and area light shadows work with non-static objects.

[rugged kernel]

hmm, then im probably doing something wrong

the light keeps leaking through

[steel meteor]

Did you enable shadows on the area light?

[rugged kernel]

yes

[steel meteor]

The light looks very soft, so have you light baked the area light? Is the light set to realtime or baked?

Also, my test is on 2022, I'm not sure what you're using and if area lights can cast realtime shadows

[rugged kernel]

the light is set to real time and neither of them are set to static so Im really confused on why it does it

[ionic flame]

how do i make realistic glass

like with custom refraction

[eternal laurel]

Check out the glass custom pass here https://github.com/alelievr/HDRP-Custom-Passes

[ionic flame]

thanks king

but how would i apply after i download it

[eternal laurel]

Well I havent tested the glass myself but it looks like its two shadegraphs so you will be able to figure it out 🥳

There is a glass scene in the project where it is set up

[ionic flame]

wait is there a project in there?

[eternal laurel]

yes the git repo is a project

[dawn sorrel]

@rugged kernellooks real

[rugged kernel]

Thanks

[noble sparrow]

Hey guys. I haven't used HDRP a lot before, and I would like to know if someone has found a workaround to the lack of camera stacking. I'm coming from URP, where it's very easy to render the viewmodel of a first person character over the environment. Is such a thing achievable in HDRP too and to what extent? Thanks :)

[eternal laurel]

@noble sparrow There is a fps custom render pass in this repo https://github.com/alelievr/HDRP-Custom-Passes

[lunar stone]

is hdrp water system released?

[scarlet hull]

Available in the alpha releases.

[lunar stone]

thanks

[round elbow]

Hey, is there away to mask lights? like set certain lights to only affect certain objects.

[long scarab]

have a look at "light layers"

[quartz heart]

Hey, I have a project I made in HDRP and I want to move it to normal built in pipeline.
is this possible?
I can Simply delete the package from the package manager and convert all Materials myself.
will this work? is there anything else I need to do?

[outer carbon]

Things like lighting and cameras and any other HDRP components would have to switch. And of course updating any code referencing them.

But yes, it's possible to switch with some work.

[quartz heart]

Awesome, Thanks!
I want to switch from HDRP to URP.
I know it's not recomended but urp seems to be much more popular today so it will be worth it

[thick swift]

Hello all, I'm using HDRP in my project and all of a sudden i can't see any shadows? I've tried adding new lights/removing old ones and removing my volume post processing but nothing seems to work, anyone know a solution?

[pallid monolith]

how can i convert uv to position on the mesh

I need to change texture on mesh based on some things from scene

[shrewd moon]

@pallid monolith There's no need to crosspost to unrelated channels

[pallid monolith]

i posted here first then realized its the wrong channel

[dawn sorrel]

#archived-lighting message

Made a thread in lighting asking for help with light leak. Probably should've made it here as I'm guessing it's to do with HDRP.

[granite marsh]

Hello guys some questions about decals

i have 3 decals inside my scene (only 2 on the screen). When i switch on the third , i go this :

Any idea, this random (sometimes, the first one turn white) sometine the second...

and when i launch the player, i've got this

[scarlet hull]

Random guess : you are overflowing the decal atlas. Defaut atlas size is 2048x2048.
Look into the HDRP settings, under Rendering/Decals

[granite marsh]

Any idea (its for merch/visual production) and i'm gonna need a lot of decals

Hello @scarlet hull
its 2048x2048 by atlas or for the integrality of all atlas inside one scene ?

[scarlet hull]

I don't get the question.
The atlas size is a rendering settings, and decal texture are pushed in / pulled out of the atlas dynamically depending on what is displayed

[granite marsh]

ive got this

8192x8192

[scarlet hull]

Unless you have very big textures, I guess you shouldn't fill the atlas then 🤔

[granite marsh]

it for 4k screen with large close up

i thought that it was 2048x2048 per Atlas

it seems that you're right, the limit size is for the ALL atlas - at the same time

[scarlet hull]

I don't get what you mean by "per atlas"

[granite marsh]

i thought the limitation wason 2048 -4096 per decals

and it seems that is for All the decals inside a scene

i crop texture size inside unity and by now, all the decals inside my scene are visibles (but blurry ^^)

thank you again

[scarlet hull]

The decal atlas is a texture that contains all the decal textures, for decals applied on transparent objects.

And not for the whole scene but "for all the decals visible by the camera"

8k by 8k should be quite enough, that's 16 2k x 2k textures.
With 3 decals that use basecolor/normal/mask map, it should fit in the atlas

@granite marsh

But of course, the larger the decal texture, less you can store in the atlas

You can use the Rendering Debugger window (in Windows/analysis menu) to view the decal atlas in the editor

[granite marsh]

ok ;:)

[lunar stone]

why is this happening

[digital spire]

Also, what's happening here? Why switching to deferred make the scene dark ?

[digital spire]

Hmm, trying to repo it in fresh project didn't happen...

[digital spire]

[sterile mesa]

How do I paint on my hdrp skybox in runtime

I want to be able to change the .png it uses.

Without precompiling one

Since I make the .png with code in runtime

[sterile mesa]

The USE CASE IS THIS: I have a MMO starfield, some different colors and nebula. When a ship enters warp, the actual stars/nebula are rendered, the skybox derenders, and you see them whip past you like StarTrek:TNG. Then when you exit warp, the skybox is drawn behind the scenes to resemble the stars and nebula where they settle, and the gameobjects of stars and nebula are derendered (still see em because they're now skybox).

Here's the full rundown https://forum.unity.com/threads/its-trivial-to-change-the-png-of-a-skybox-right-it-should-be-look-what-i-want-to-do-warp-drive.1319313/

[bold wadi]

Hey everyone ! I made a png texture and I would like to know how to make it so the transparent part is, well, transparent in the shadergraph

[rose shore]

https://forum.unity.com/threads/multi-render-pipeline-asset.1319580/

Would love some help with this if people have experience with it!

[steel meteor]

If your texture, check that 'Alpha is transparency' is true. On your material, check that Surface Type is set to Transparent instead of Opaque.

[tidal flare]

It seems that the HDRP package is crashing my user's even when on decent hardware, is there anything known to cause consistent crashes?

Additionally if it helps it seems that a common issue is that the unity crash reporter never opens in any of these cases

[tidal flare]

actually forget this

said they were running decent hardware

when I looked into it more, they didn't have a gpu

[open tree]

how do I shift the horizon in HDRP physically based sky? I want the sun to go below horizon above sea level.

to achieve this type of effect

[scarlet hull]

? Below horizon + above sea level seems impossible to me, logically speaking

[open tree]

@scarlet hull sorry probably I wasn't clear. I want the horizon level where the sun goes down, to be above visible sea level.

like in this image, there a dark gap between the sea level and sun

this is what I am getting, I want it to be little above the sea level

[scarlet hull]

What about cheating with the sea level of the PBSky ?

[open tree]

that's what I thought but increasing sea level isn't doing anything

[iron siren]

Could somebody confirm me if my understanding of surface inputs and details inputs is correct?
If I understand the documentation correctly, they both do the same thing, the only difference is that the detail and mask map will contain information of several layers at once? So if I fill the base map + normal map, it would be the same as using a detail map having albedo desaturated in R channel and the normal map X/Y in the required channels and smoothness channel at 128, is that correct ?

Meaning if we only use albedo and normal maps, we don't really need detail and mask map

But if we need them, it's better to pack albedo and normal map in the detail channel and leave the base map and normal map fields from the surface inputs empty?

Basically, either one or the other, filling everything is redundant for some layers then?

[scarlet hull]

If you don't need the detail inputs, don't use them.
The detail map only has albedo & smoothness variations (no color) and normal, when the basemap has color information.
Usually you would use the surface inputs with non tiling textures for the overall look of the asset, and add detail with higher tiling value and a tiling texture to add close up informations

[iron siren]

So you still need to fill the base map texture even if the detail map contains the albedo data? You can't just leave it empty and change the color of the base map if the detail map is filled?

I'm trying to import some Daz3D clothing which offers some specular map which should be the smoothness map for Unity if I understand well? But to use this map, I'd need to create the detail map then since there is no smoothness map in the surface inputs? Not sure if it's worth the efforts though

[scarlet hull]

The smoothness is in the Alpha channel of the mask map

[iron siren]

Oh indeed, I mixed it up

[scarlet hull]

No, you don't need to fill the surface inputs to use detail map, what I'm trying to say is that you mesh aknowledge that the detail albedo is only to add variation to the existing base color ( it is working like an overlay blend in photoshop), it won't be able to drastically change the color value

base color blue can get lighter/darker until white/black, but won't change to red with detail map

[iron siren]

Ok got it

For the mask map, if we want a neutral metallic and occlusion, it should be RGB 128 on average right ?

And if we don't use detail mask, then the blue channel of the mask map can be ignored ? Which only leaves the alpha channel for the smoothness? Did I get that right ?

[scarlet hull]

If you want to keed controll of the metallic value with the slider, set it to 255.
Occlusion should be also 255 : white = full brightness.

So if you don't use detail mask, the mask map value is :
R = 255
G = 255
B = whatever
A = smoothness

[iron siren]

Got it, thanks a lot for your time and explanations

[scarlet hull]

This might lead to a material that look dark due to metallic beeing maxed out, you'll have to reduce it with the metallic slider value, but this way you have control over it, whereas if you use R = 0, the slider will have no effect as it's multiplyed with the value

[iron siren]

Ah got it, thanks

[iron siren]

Is there a way for HDRP lit layered to handle semi transparency for the additional layers ?

My texture has one spot with some semi transparency

But the hdrp/litlayered doesn't care?

[iron siren]

Nobody?

[sacred veldt]

How I can fix these reflections just being not visible sometimes?

[shrewd moon]

You can't

This is a fundamental limitation of screen space reflections

The other option is to use something like box projected cubemaps, a planar reflection probe or fully ray traced reflections

[sacred veldt]

planar reflection probe mhm

[covert summit]

Hi, recently I have bumped into this kind of block artifacts problem on the multiple projects. it seems there's too many volumetric lights intersecting but how can I increase the limit? Or any workarounds?
I have searched about this problem but I can't find any info of this problem...

[barren goblet]

where can I get a free megascan scene for HDRP?

a complete scene

[iron siren]

Still nobody here to let me know how to have the HDRP lit layered shader handle 50% opacity on the extra layers? At the moment, it displays all pixel with opacity > 0% as if it was 100% opacity. Is it a wrong set up on my side or can't the HDRP lit layered shader handle semi opacity on the additional textures?

[upbeat hill]

I'm using the latest 2022 version, and for some reason, my Post Processing Effect is showing up in game, but it isn't showing up in the scene view OR the camera preview.

I have post processing turned on in the scene settings, as well.

Does anyone know what might be going wrong here?

[dawn sorrel]

Is it the same in game view?

I often see things that I don’t in game view, maybe not the issue here lol
Nice SCP SL though, I like that game

[mellow condor]

it's due to the light tiling optimization, you can disable deferred tiled in the camera settings custom frame settings rollout under light loop debug

but your scene will render too slowly if you disable this

i think you will have to fake this effect for it to perform well

[mellow condor]

what do you mean megascan? do you mean like an unreal engine style environmental scan? you can use the ones from hdr studio in the asset store

other than a camera orbit you can't do much in those scenes because they don't react to anything 🙂

[mellow condor]

what is the objective? you should probably not be using layered lit for this

[mellow condor]

you can use an hdri for the sky

[ashen shore]

Does anyone know how to apply volume/post processing to UI?

[distant lintel]

Hello all. When using urp its been easy to upgrade the materials, but in HDRP I cant seem to find an option to upgrade materials in project to HDRP.

Is it not possible, or am I missing something ?

[iron siren]

I want to create customizable clothes. One texture is the background of the cloth, like a wool texture. Then I want to apply a logo on the cloth. But the transparency doesn't seem to work.

[iron siren]

I don't think there is an upgrade feature. IF you moved from standard RP, the materials of your objects won't change and they'll still be using the standard RP shader which doesn't work in HDRP and displays as purple like you showed. You need to go to your gameobject and change the shader from standard to HDRP/Lit

[eternal laurel]

I dont think the layered lit shader is appropriate for that. Either make a shader grapg shader that samples both textures and mixes them how you want or use something like a decal for the logo

[iron siren]

Isn't the lit layered shader exactly for layering textures together?

Why wouldn't it be adequate for my use case?

I'm getting good results so far actually, it's only the semi transparency which is a bit strange.

I did write a custom shader to merge texture by I'd prefer to use built in shader since my shader graph knowledge is close to zero...

Here is another use case for my project:

I'm using the lit layered as a skin shader (using the subscatter option). The first texture is the face texture without the eyebrows. Second texture is the eyebrows. It's working quite well, I'm not looking for AAA quality so I don't mind if it's not realistic looking.

Transparency seems ok here, but I've been trying to add a heightmap to give the eyebrows some more height however it's working weirdly.

From my understanding, a heightmap is a greyscale texture with white being pixel forward and black being pixel backwards. But when I apply, I can't get the eyebrows pixel to stretch out, moreover the whole face texture gets backwards too while only the eyebrows layer should be affected.

Here is the same with amplitude set to 5, I was expecting the hair on the eyebrows to move forward, but instead, the rest of the face seems to move backwards while the eyebrows don't move at all.

I thought maybe using grey 127,127,127 instead of full black background could fix the problem but it only reduce the strangeness

When I increase the amplitude, the eyebrows still won't stick out, only inwards.

Using pixel displacement mode

If I use the vertex displacement mode, the correct result appear, only the eyebrows vertices are stretching out as expected.

But I need the pixel displacement instead. Why don't they work the same?

[mellow condor]

if the clothes are customized in a systemic way, at least as far as i can be familiar with any system in any other game, you have two approaches:

(1) use shadergraph and create texture slots for the decal positions
(2) composite in canvas, and use a snapshot of the canvas as the main texture

it is unusual to use layeredlit to achieve your goals

[valid token]

i'm going through this video enabling raytracing for the demo scene. when i enable screen space reflections, i'm getting these cube artifacts around the edges of objects. anyone have any idea what the issue is?

https://www.youtube.com/watch?v=ad9f_nKU0ZA

[glacial fossil]

those boxes seems to appear only on bright areas. I think you are hitting the limit of per tile light sources (I dont really know much about lighting in hdrp, if I remember correctly, the screen is divided into those tiles which are somehow used in the lighting calculations). take a look at this https://forum.unity.com/threads/hdrp-tile-cluster-lights-rendering-bug.667234/

[covert summit]

Thank you so much for the advice! I have looked into it and disabling big tile prepass in Light loop debug solved the problem!

This document also help me understanding tile/cluster light rendering
https://advances.realtimerendering.com/s2018/Siggraph 2018 HDRP talk_with notes.pdf

[mellow condor]

yes but the game will run too slow

what is your objective?

[covert summit]

At this time, I use it as prerender content. But now I understand what causing the problem so I can tweak settings like ranges and numbers of the lights in the scene

[violet owl]

is there a way to use the physical sky with a skybox? i want to have a sky at night instead of a black void but i can't find a way to use the physical sky at the same time

[shut spade]

Why does this keep happening beneath the camera

It messes up all light and shadows

[twin holly]

how can i get rid of this automatic shadowing/darkening of this mesh? it seems to change automatically in occurrence to a directional light

[shut spade]

Literally where the hell is shadow distance in HDRP

With min and max

It's not in the volume override

[steel meteor]

Shadow cascade should be in the volume override https://docs.unity3d.com/Packages/com.unity.render-pipelines.high-definition@12.1/manual/Override-Shadows.html

[iron siren]

Could anybody give me the name of the HDRP/Lit properties for Tiling and Offset? I'm checking the Shader code but I can't find any vector or float related to it
I can see this :
[HideInInspector] _InvTilingScale0("Inverse tiling scale = 2 / (abs(_BaseColorMap_ST.x) + abs(_BaseColorMap_ST.y))", Float) = 1
But there is no _BaseColorMap_ST property in the file? Where does this come from?
Plus it's a hidden property so it shouldn't be the one I'm looking for.
The goal is to be able to change the tiling and offset at runtime. But can't find those 2 properties in their code. Quite strange.

[open tree]

In HDRP how do I apply texture to the moon? I added a surface texture but it is not working, what am I missing here?

[eternal laurel]

increase the angular diameter

[iron siren]

Nobody knows this?

[open tree]

@eternal laurel thanks, that worked

I have another problem, I am controlling the day-night cycle using a C# script. I have 10-12 reflection probes in my level, I need to update them every hour or so in game time. I know "on demand" mode does that, but how I do it?

I need some examples or documentations for the coding process.

[eternal laurel]

https://docs.unity3d.com/Packages/com.unity.render-pipelines.high-definition@15.0/manual/Reflection-Probe.html

"• On Demand: Updates the Probe's capture data when you request it. To do this, access the Probe's HDAdditionalReflectionData and call the RequestRenderNextUpdate() function.
This property only appears when you select Realtime from the Type drop-down." documentation exists

I would suggest you pre bake 4 sets of probes and blend them according to the time of day

rather than rebaking

should be faster but more memory intensive

[open tree]

so 4 reflection probes per location?

[open tree]

how do I access the probe's HDadditionalreflectiondata script? I mean what exactly I have to do in my Daynight cycle script? sorry I am beginner.

[eternal laurel]

its a Component on the reflection probe you get it like any other component. If you dont know that, stop doing a day/nigh cycle and go do a basic course on learn.unity.com

[open tree]

okay thanks

[open tree]

Is there any way to exclude VFX particles from DLSS? they are causing bad ghosting effects.

[mellow condor]

no

[mellow condor]

HDProbe is the name of the component

[iron siren]

How can I change the tiling of the main layer in HDRP/Lit at runtime? I can't find the property code for tiling or offset.

Is there another place to get this information if nobody knows here?

Also, is it possible to change the layering list of the HDRP/Lit Layered at runtime ?

[open tree]

I am facing a weird issue. I have some reflection probes set to realtime on demand mode, when I hit play in editor I am getting complete black screen until I move my camera , then it flickers and no problem after that. If I set the reflection probes to bake mode it doesnt happen. Getting no error or anything. any idea?

[mellow condor]

aren't you trying to use LayeredLit for a clothing system?

[open tree]

I think I figured out the cause of this issue but still no idea how to solve it. My reflection probes are on demand, so they are blank and probably causing the issue. I update them at certain time of day but also I called the update function in void start() . But still getting this issue.

[iron siren]

Yep, still on it ahah 😉 For tiling and offset, I found out they are linked to the texture directly and they have unique methods SetTextureOffset and SetTextureTiling to change them. It was a bit confusing because other shader have exposed properties to change those values. Moreover, in the editor in the lit shader, we can only change the offset and tiling of the albedo, but it seems that using this code, we can also change the tiling and offset of the normal map independently which is nice, though I'll need more testing to confirm it's really working.

The only remaining issue is semi transparency not being handled properly in both opaque and transparent mode. I think it's a bug. I've opened a ticket but no news so far.

[ionic flame]

https://uploadi.ng/70E3SsGG

for some reason when i obscure some of my glass texture infront of a light it does this

[icy pollen]

If it's any consolation, that's exactly how the ceiling lights in my office behave! If they have rectangular grid on the plastic sheet under the light you get that holograph effect. Call it a feature 😉

[shrewd moon]

Probably a screen space reflection (or refraction) artifact

[ionic flame]

this actually helped lol thank u

[dawn sorrel]

Hey everyone, i'm facing a strange issue in HDRP with Ray Tracing. Essentially I have a capsule for my player, I obviously don't want to see a capsule and just want to use the collider, sure I could probably use an empty with a collider, but is that really necessary or is there some option in the settings to fix this issue.

I've broke it down to what part of the mesh renderer is causing this and that's the Ray Tracing tab where it says Dynamic Transform. If I turn it to off it does same black artifacting

Okay it's something else, even if I delete the capsule the black artifacting still happens

Broken it down even further that the ultimate culprit is Screen Space GI Ray Tracing, apparently it loves and needs the capsule lol

[cinder root]

How do I stop a HDRP decal from drawing on objects after being spawned? I'm dropping objects on a explosion scorch and new objects on top look scorched

[dawn sorrel]

I'd take a guess and think maybe decal layers? You can find the option here

[cinder root]

that didn't do it

[eternal laurel]

That will do it. Create a scorched layer. Wheb you do your explosion move neardy objects to that layer and set the decal to only affect it. Simply ticking the box wont do much

[cinder root]

That's a bit of a pain. I can see how it would work though. But I'm going to try a third party asset instead

since already have it. Not looking to do anything fancy with the decals anyway

[dawn sorrel]

Also you can - the material on objects such as a player turn off "Receive Decals" on the material udner surface options

[eternal laurel]

Pretty sure any third party asset wont have a exclude new objects option by default

Buuuut gl hf

[cinder root]

it could have been this simple though:

thanks for info anyway

[lofty hatch]

https://assetstore.unity.com/packages/templates/packs/snaps-art-hd-warehouse-155229 this says dude to changes in 2019 and up it's not supported. Does anyone know off the top of their head what changed?

[iron siren]

Can somebody tell my why this texture is shown as being 85.3MB in size while it's only 135KB in windows explorer?

OK, nevermind, it's the size in RAM which is shown here which is the decoded version of the one windows explorer shows.

[true zealot]

Textures in Unity are also imported to formats that are ready for runtime graphics. The format you use to author the asset has no effect on the size once imported

If your texture is just a black and white mask you might want to choose to import it only as one channel.

[iron siren]

Indeed, I was not aware a PNG could be greyscale and keep its alpha layer. For the matter of easy use, I want to be able to use only 1 texture for both a diffuse texture which will be colored AND a mask texture to know the opacity to show.

I was saving my PNG as RGBA thinking it couldn't handle greyscale due to my ignorance lol. After understanding a bit more about shader and images, I'm starting to get the hang of how those things work, at least a little bit better 😉

Thanks again!

Hm, it's a bit strange, I did change to greyscale which reduced the size in windows explorer from ~182KB to 129KB, but Unity still shows the same size unpacked.

64MB in both RGB or greyscale. Is it normal?

[true zealot]

As I said,

the format you use to author the asset has no effect on the size once imported

If it's still imported as RGBA8 without compression (or whatever) then that's 8 bits of R G B A

[iron siren]

Oh got it

Indeed, enabling high compression reduced to 16MB, quite a difference

And using crunch crompression even lowered that to 308Kb in low quality. But I still don't see a difference in the shader graph preview. Does compression not affect the preview?

[true zealot]

I have no idea. I was saying that if you just have a black and white texture without alpha then you could also switch the format to R8 or 16, as all the channels are the same

[iron siren]

Ah, got it. I do have alpha though, so won't be able to use this way.

Anyway, you enlightened me once more, thanks a lot for this! 😄

[barren goblet]

why this guy implement Nanite in unity?
do you think any project will use this kind of art asset?

small teams have no budget to use this art style

[sterile mesa]

how do I set the brightness of a gameobject in HDRP? I want to change an item to absorb more light aka be brighter

[glacial fossil]

Id imagine thats mostly useful with 3d scans which are quite easy to make

[dawn sorrel]

Higher end graphics are pretty easy to make, despite the popular belief that they aren't. But getting them to run in a performant way is the actual hard part 😆

The reason why most indie games are low-poly or some mix art style is because most indie devs instantly assume that it's super hard to reach realistic looking games. I'm saying this from personal experience. Three years ago I was sure that I could never get my games to look realistic, but nowadays it's super easy and pretty fun actually. It requires a little bit more learning, but it's worth it. If you want examples of Unity indie games with pretty damn good graphics, check out Road To Vostok and Project Z for example.

[barren goblet]

but if a project is going to realistic style, especially 3d scans, why not choose UE5?

The Nano Tech has no value😂

[dawn sorrel]

I'm not talking about nanotech. You don't need Nanite nor it to have a realistic game. We've been making pretty damn realistic games for almost ten years, after all.

I personally think that making models should not just be as easy as just importing them into an engine and enabling a tool. But I like the challenge of optimization so it's just my own stupid opinion lmfao.

[shrewd moon]

HDRP and UE5 are very close in visual fidelity, but beyond that the engines and their workflows are quite different
A tool like this would probably have have value for a studio that's looking for more feature parity with UE while having chosen Unity out of necessity or convenience

[dawn sorrel]

At this point the only difference between unity and UE is that Unity doesn't have a system like Nanite, or actual realtime GI and they don't make every tool they buy free for everyone.

For me, those don't really matter since the base engine is good enough for my every need.

[barren goblet]

How much price do you think the nanotech plugin should be?

[dawn sorrel]

Let's be real here, Unity is going to make something similar at some point. They know that they're losing customers if they don't. Same goes for actual GI.

[barren goblet]

unity is far from here, they just finished adaptive volume GI, that's very old school tech😄

[dawn sorrel]

That may be a small base of customers that need things like that, but since unity is aiming for also cinematic and movie creators so they'd just benefit from such tech.

[shrewd moon]

I really don't have an opinion on that
They'll price their assets according to what they think they'll target demographic is willing to pay
Usually a studio that has the resources to produce HD graphics has investor backing behind it as well

[barren goblet]

lol, HDRP has a trend to make small cinematics, the digital human and lion king

but cinematics don't really need Nanite, it needs realtime GI like Lumen

[loud leaf]

HDRP has real time GI using hardware ray tracing. If you're targeting photorealistic graphics / cinematics, you're already targeting GPU's that can do hardware ray tracing.

[dawn sorrel]

Valid logic, actually.

Also, the reason why people usually choose unity over unreal is the general requirements for the engine. I literally got hdrp and volumetrics to run on a seven years old PC on 30 fps. No wonder unity is the most used engine, you barely even need a good PC lmfao

[loud leaf]

I'm not a huge fan of Lumen because of the delay/blobs/etc, maybe the scheduled updates will make it better.

[dawn sorrel]

Lumen also takes a fuck ton, and I mean a fuck ton, of performance, which is a total minus in my books. Like yeah, obviously. You get amazing lighting, but it takes so much performance that you either need a beast of a PC or just don't use it.

I view UE5's graphical jump as a total minus in general, tbh. I personally still use the Xbox One to play games, but when studios aim to use this advanced graphical stuff they most likely only aim to release on next gen.

[autumn harness]

Hey guys is there any way of using tree compoment for hdrp?

because im getting pink error textures

[scarlet hull]

The tree generator ?
We don't "officially" support it in HDRP, but at the end it's just generating a mesh with materials and textures, if you change the shader to HDRP/Lit with the same textures it should work.

[autumn harness]

Yeah but unfortunately when I change a bit of the mesh to fit what I want like extending the size if it's a bit too short than it swaps the mesh with the pink one and it gets really annoying quickly. I just want to know how to make it not swap the mesh when I do slight changes.

[scarlet hull]

I don't think you can avoid that sadly :/

Maybe if you create copies of the materials in your assets, and force assign them in the tree generator fields (not into the mesh renderer) it will keep them 🤔

[autumn harness]

I'll try that one out. I don't know where the options for the tree gen is though.

[autumn harness]

also yeah that didnt work it just continued forcing them to the pink color

[dawn sorrel]

Why is it changing HDRP Volume layers makes local volumes stop working

Is this a me issue, or a HDRP thing.. Because I can't find anything that would rule out either.

[scarlet hull]

@dawn sorrel The camera has a volume layer mask, making it that only the volumes in the listed layers will affect the rendering of specific cameras.
If you change a volume to a layer that is not in this mask, it will no more affect the rendering.

[eternal laurel]

And its always anoyed me that adding a new layer does not check it by default in the camera masks

[dawn sorrel]

Where do you find the camera volume layer mask? I can only see culling

[scarlet hull]

"Environment" section, "Volume Mask"

[lone river]

[shrewd moon]

@lone river Please post only to one relevant channel

[scarlet hull]

The editor camera should reflect the value defined in the main camera of the scene

I've got no camera in the scene as it's loaded in an additive do not destroy scene

I'll just put one in for whilst i work

[scarlet hull]

@steep verge Sorry what ?

Something about a real-time shader

Most likely asked "why hdrp can't render a realtime shader in the viewport"

[glacial fossil]

Ah yeah, they havent enabled Always Refresh from Scene view View Options toolbar https://docs.unity3d.com/Manual/ViewModes.html, thats most likely what they mean, by "realtime" they mean shader that animates over time

@steep verge

[worn flax]

can anyone help with procedural world generation in hdrp

[glacial fossil]

Thats not necessarily hdrp related, procedural generation should be the same on all pipelines. Try to ask on the coding channels instead

I think im using hdrp but there's an "Exposure" node that I can't find here

I'm getting a lot of this on building:

  everything seems fine...

can anyone advise me on how to find the problem texture or where i can fix this issue? cheers

ok i am a big dumb nevermind. - did not realise Hdrp quality settings panel defaults to building in 'low quality' mode

[barren goblet]

what?

[shrewd moon]

You can specify a default quality level by platform, but I don't think there is a "low quality" build mode?

Any tips on how to make my hdri sky cubemap less boxy? Like what effects to add in photoshop or on Unity?

Mine feels a little bit too much that I'm on a cube (which I know I am 😆 but still)

[shrewd moon]

https://youtu.be/XZmr-XYRw3w
Cubemaps must be authored with very specific perspective distortion

Anything that's not drawn in 3D projection mode won't have the correct perspective

what is the skybox material for HDRP?

I was using the Legacy one, which has 6 sides

[exotic fable]

oh cube textures work, got it thanks !

[fresh wolf]

I just switched to HDRP and Im getting this really weird shadow that moves with me.

And Im getting an error

[glacial fossil]

Seems like shadow cascade border. You are clearly having some shadow acne close to camera

[exotic fable]

Hi any tips on how to set up lightning for a space scene? My current problem is that I have a tight coupling between the skybox and the lightning on the scene. If I change the skybox, I need to change the entire light settings for the scene. It's also hard to manage making the scene look well lit enough and the skybox not looking too bright

I'm using the Exposure Compensation in the HDRI Sky and Directional light intensity to manage this

Exposure is set to automatic

If anyone has some preset values for space scenes it would be great 😛

Should I use fixed exposure?

[analog merlin]

hi , im trying to make stylised "wiggling" shadow effect, plan is to offset shadow map with slight noise, but i cant figure out how to hook up shadow map (single directional light) in hdrp

[analog merlin]

there is great talk about light in hdrp: https://www.youtube.com/watch?v=yqCHiZrgKzs , imo clamping exposure min/max values might help you

[fresh wolf]

Thanks, but could you please dumb that sentence down for me. I'm really new to unity. How would I go about fixing this?

[exotic fable]

yes, that eally worked, thanks! I ended up clamping min and max close together. I was checking other space game and it also seems they have fixed exposures as well

[onyx depot]

Hey.. im trying out hdrp for the first time. My point and spot lights doesn't seem to emit any light when the directional light is set even if i put it in full intensity.. it will show up when directional light is disabled or if it's intensity is brought down to almost zero. And i should mention the spot and point lights are inside a structure which is decently dark.

[glacial fossil]

You must change the bias values in order to get rid of shadow acne

[native pilot]

I know HDRP isn’t for low power devices but if I am targeting desktops that go from low power to high power can I stay with HDRP or should I just bite the volumetric fog and return to URP? I don’t believe I’ll ever go on mobile.

[onyx depot]

I figured out there is light from skybox even inside fully closed off places.. how do i fix that?

[eternal laurel]

Place a reflection probe inside the space

[onyx depot]

So i have to manually do it every enclosed space?

[fresh wolf]

Thanks. Where would I find that setting?

do baked reflection probes affect reflections of static objects?

for example, if I have two metal walls marked as static and bake the lighting with no light probes, will the metal walls reflect each other during the baking process?
if I then add a baked light probe and rebake lighting+bake the light probe, does the lightprobe affect what is reflected on the already-baked walls?

Anyone got any pointers, ideas or resources ?

[worldly crest]

looks like this: instead of trying to model 1000000 different variations of zombies in varying damaged states, they said, lets just create a few internal wound models that we can slap into the zombies.

but you want to be able to see the wounds. for example, if you place some guts inside the zombie model, but the zombie's tummy hasn't been destroyed, then you wont see the guts behind the tummy.

so they said: ok, let's place a white splatter texture on the tummy. this will tell the renderer to make the tummy pixels transparent where-ever the white texture is on. then you can "see through" the tummy and see the guts. then they use the ellipsoid to better scale the tummy texture and guts so it fills up the transparent hole better. idk the exact implementation. but that seems to be the gist of it.

rather than actually deleting parts of the model, or creating a million different zombies in different damages states, just make the damaged part of the zombie transparent, then you can stick in some gore models in the zombie. so they aren't dynamically destroying zombie meshes, just turning part of the zombie mesh transparent

[eternal laurel]

Well sure I understood this much from the pdf too🤣. Is the splatter texture rendered in UV space ? How exaxtly is the alpha of the splatter and the clip from the elipsoid combined ? Stuff like that.

The actuall gdc talk would be nice but I cant find it in the vault or anywhere

hey i really need some help i made a character in blender that look like this

but when i upload it to unity in hdrp its just look like this

and its becouse i have no idea how to setup the materials

And I cant find any youtube video explaining it

[dawn sorrel]

Can someone explain why changing the ground tint or turning the cloud layer on affects the lighting of the scene (quite dramatically)? I would think these are background elements that shouldn't impact anything

[dawn sorrel]

This is not at all uncommon. Blender and Unity use different renderers. You are encouraged to define materials inside unity and spend more time on them there than in blender. They will never look the same.

[true zealot]

it's hard to tell from a screenshot with no movement, is that z-fighting or are the normals just weird?

[dawn sorrel]

Unsure but for a sec I thought this was a real picture

[shrewd moon]

The lighting of the scene could be weird as well, hard to tell
It may be smart to do tests in the sample scene where you can be sure the lighting is okay

[scarlet hull]

@red needle

• Check the lighing in the scene (or put your model in a already correct lit scene like mentioned)
• What are the textures you've showed used for (can't see the whole names) ? Are they properly imported for their usage (type normal for normal map, sRGB disabled for metalix/smoothness/specular ...) ?

[red needle]

Thanks but I think I found out

[dawn sorrel]

Yo Remy, were there any big changes to HDRP in general in the more recent versions? I could run a hdrp game at around 30fps with older versions, but now I always go below 22. Had to switch to urp because of this.

Even on the lowest quality settings my performance doesn't change at all.

the backbuffer is the render texture so it shouldn't really matter if there is or is not a screen. waiting until the end of the frame, and then blitting using Graphics.Blit works

[sacred veldt]

its any easy way to make like switch between baked lights and realtime?

[dawn sorrel]

You could just switch your scene with realtime lights to a scene with baked lights on the go

[dawn sorrel]

Well you just clear the baked data if and set all lights to real-time you want to go to real-time

[mellow condor]

is there an event when the gpu has finished rendering?

for example, if i have a camera targettexture sent, and i render to the camera

i would like to know the exact time, possibly even from not the main thread, that hdrp has blitted the final pass's output to the render texture?

[mild wing]

https://docs.unity3d.com/Manual/ExecutionOrder.html

OnPostRender() is what I'm using for after all rendering is completed.

[mellow condor]

Note: These callbacks only work with the Built-in Render Pipeline

anyway the hdrp equivalent for them occur after the main thread work for the camera is done

[mild wing]

They work for URP in my case.

I know the coroutine wait until end of frame will work for HDRP as well.

[latent mulch]

hey people! We have a project in Unity 2020 LTS with build-in pipeline, and we want to remake it in HDRP and we are considering using a newer Unity version for this, do you think it is recommended? Does 2022 has stable enough HDRP or should we stick to something like 2021 LTS ?

[scarlet hull]

It depend on where you are in the development.
If you are still in a quite early stage, you could even go for the current 2022.2 betas (current beta is 7, the final version should be far away), and later upgrade to 2022.3 LTS.
Else, if you want to ship soon-ish with a stable version, stick to the 2021LTS, but you will miss some of the most recent features.

[latent mulch]

makes sense. We're going with 2021LTS eventually, thanks!

[signal osprey]

how do I bake all dynamic objects in the reflection probe, including obejcts which don't have the "reflection probe static flag turned on" ?

[shrewd moon]

I expect you would enable the reflection static flag, or use a realtime/on-demand reflection probe

[pulsar skiff]

how do i do something similar to camera stacking (urp) in hdrp? i need it for my weapon viewmodels

[eternal laurel]

Custom render pass

https://github.com/alelievr/HDRP-Custom-Passes/tree/master/Assets/CustomPasses/FPS Foreground

[pulsar skiff]

ah thanks

ill look into them

[pulsar skiff]

im using unity 2021.1 with hdrp 12.1 tho

the only version this has are 2021.2/3, 2020.2/3 and 2022.1

[eternal laurel]

Concept is the same🤣

[pulsar skiff]

are you telling me to rewrite it?

aw heellll nah

[signal osprey]

that's cool, I didn't know there was an implicit exceptions made when switching render mode.

how do you guys like HDRP?

[eternal laurel]

Very much

[pulsar skiff]

love

[signal osprey]

@eternal laurel @pulsar skiff what do you render in it - can you show?

[pulsar skiff]

oh

i render weapons

its a fps game

you still there?

@signal osprey

[pulsar skiff]

i hate my life

why is this error in the compositor not going away?

[signal osprey]

show us your stuff, dude

[pulsar skiff]

What do you want me to show

The weapons are several gameobjects on a layer named. Viewmodel

I also have a second camera that only renders that layer from before i upgraded from urp to hdrp

In urp there was a thing called camera stacking that rendered that second cameras view onto the main camera

You are asking me to show you stuff without telling me what you want to see

[signal osprey]

the game

[pulsar skiff]

Here is a pic from before upgrading to hdrp with the camera stacking and the weapon being rendered on top

Here i sent some more

Do you want to see the hierarchy?

I cant send you a pic but this is how it looks like:

MainCamera:

-viewModelCam

-flashlight

-weaponHolder:
--pistol
--shotgun
--grenade
--ar2
--physcannon

Main cam renders every layer except viewmodel layer

viewModelCam only renders the viewmodel layer

[signal osprey]

no i know how to use stacking, i was only curious to see what benefit of HDRP over built in

[pulsar skiff]

What do you mean? Hdrp looks so much better

Im doing it for the graphics

Vfx graph, shader graph and decals

Volumetric lighting ,ray tracing, hair shaders

You came here to ask me why im using hdrp?

[pulsar skiff]

Seriously?

Acting like you are goig to help me just to say what is the benefit of using hdrp in the #archived-hdrp channel

What did i do to deserve this

Are you guys seeing this?

Ig im gonna have to do something about it myself

[signal osprey]

what a drama queen 🤣

[pulsar skiff]

You were literally acting like im waisting your time when it was the opposite

[mellow condor]

a custom pass blit appears to fail only in release builds. when built with development mode checked, everything works 😦

[pulsar skiff]

hey guys, i made this shader named water which should look something like this and actually did look like this in urp and hdrp deffered renderer but as soon as i changed my lit shader mode to forward every material using this shader became invis, how do i fix it?

[eternal tendon]

guys please help. So i added hdrp to my project. And after adding it everything turned pink. Then i foun how to fix it on internet and now every texture is blue

[dawn sorrel]

im desperate with the grass in hdrp, what am i supposed to replace the details with?

[lament mango]

uhh... does anyone know why i got this visual glitch? is it a shadow bias problem or something?
(edit: you can barely see it)

increasing the shadowmap res made it even worse

[lament mango]

ok so i did a bit of playing and it seems to be coming from the directional light angular diameter

[steel meteor]

Yes, setting to angular diameter to 0 will fix the issue, but then you have sharp shadow edges which you might not want.

To get around this, you can use the Graphics > HDRP Global Graphics > Shadows settings to change the defaults shadow cascade effects. Playing with the Cascade count, Border and Split settings can help.

Or, it might be better to add a 'Shadows' override to your global volume, set the cascade count to 4 then play with the settings in there.

[lament mango]

yea i did tweak the cutoff and blend of the cascades and it fixed the issue
thanks anyways

[ionic flame]

in my scene i have this issue

i think its a little too dark up in the corner

all light comes from the emissive lights on the ceiling

[kind hollow]

https://www.youtube.com/watch?v=Ww3lLYQqg_w maybe is this helping you, sound familiar

[pulsar skiff]

hey guys. ive come across a problem with recently on hdrp 12.1 and camera stacking

_first off, here is the scene set up:

1-a main camera that renders every layer except "viewmodel" with the depth value of 0
2-a second camera "weapon cam" that only renders the viewmodel layer witth a depth calue of 1 and the background type of "none" to achive

the depth value and backgrounds are set like this to achieve a effect similar to urp's camera stacking to avoid weapon clipping

3-and at last, a planar reflection prone

_the problem:
as you can see in the gif a portion of the "weapon camera" goes white when the planar reflection probe comes near its field of view?
it doesn't happen with the normal reflection probes

_things ive tried:
ive tried excluding the probe layer that the planar probe is on(basicly making it so the camera dosnt render reflections from that probe) yet that did not achieve anything

this problem is really bothering me and any help with this issue would be appreciated .thanks for reading

also please ping me if you respond, thanks :)

[summer glacier]

You got a few ways to go around this, one is switching to medium quality shadow filtering. Less nice/smooth looking shadows, but the issue will be gone.

Another is turning on cascade blending, increasing it on every cascade, and lowering angular to 0.4 or thereabouts.

I reported this bug a long time ago.. but HDRP doesn't care much about high quality shadow filtering except for demo purposes, so fixes are slow unless they need it. So many issues and bugs I've reported related to high quality shadow filtering (even though it's a massive quality increase compared to medium..)

[summer glacier]

You shouldn't use camera stacking in HDRP, extremely high CPU cost and there's nothing you can do about it. It's not like URP/built-in.

[pulsar skiff]

what should i do?

i want my weapons to be seen in a different fov then my normal view

i tried the compositor, everything went white. i tried custom passes, nothing happened

following official unity tutorials

[summer glacier]

I remember many people do the trick in a custom shader for the weapon itself, what to do exactly is more complicated, (google around there's many threads about camera stacking alternatives/what to do in HDRP)

[pulsar skiff]

i spent like 2 days looking for solutions

i did not see any shader related things?

[summer glacier]

But for UI you can use this: https://github.com/alelievr/HDRP-UI-Camera-Stacking
only usable for UI though

[summer glacier]

I'm not sure about this myself but I do remember reading a few solutions when I was googling for camera stacking alternatives, wasn't for FOV though but there's probably something out there

or post in HDRP forum section

[pulsar skiff]

how bad really is the performance?

oh nvm

its like 30-50 fps

[summer glacier]

don't remember exactly but it's pretty bad, you can check it out in the profiler

[pulsar skiff]

=|

[summer glacier]

there's also a GPU cost, not just CPU

[pulsar skiff]

ik

so urp does it in a diffrent way resulting in more performance?

im really tired of searching online and not finding any solutions

what im doing rn was recommended to me by a friend

[summer glacier]

https://forum.unity.com/threads/fps-gun-rendering-fov-corrections-and-no-clipping.893875/
https://forum.unity.com/threads/fps-sample-shader-graph-for-weapon-fov-not-working.576796/

[pulsar skiff]

alright!

ill look into it

so both of these change weapon fov too?!

great!

thank you so much!

[pulsar skiff]

the shader is broken af with lighting

it just looks black

except the emissive parts given to it with emissive map

oh nvm

the maskmap was broken, just had to remove it from the graph

how do i fix the clipping? this only distorts the model to look like a different fov

@summer glacier

[lament mango]

render the gravity gun on another layer

above the main scene

thats how games usually do it

[pulsar skiff]

but how

thats the thing

im trying to avoid using two cams and depth

because it costs like 50fps

maybe custom passes?

i tried them before but i couldn't get them to work

[lament mango]

im not sure exactly how but no not by using 2 cameras

you need to tell unity to first draw everything else and then draw the gravity gun

[pulsar skiff]

Ah nice. How to fix weapon clipping urp

[pulsar skiff]

as if thats not what im trying to do xD

[lament mango]

this is me looking at a wall

idk why the resolution is doiung this

hey man, i did as the tutorial said on both the deferred renderer and forward renderer and my weapons are not rendering at all. i remember following this same tutorial before and got the same results as now. here is my custom pass

[pulsar skiff]

works in scene view but not ingame?

[pulsar skiff]

okay got it to work but things clip through eachother and are seethrough and... idk what is going on

the hand can bee seen through the handle. the tip looks weird , mesh is messed up

visual effect graph is uhhh

this shit is broken man

@lament mango

this is it "after opaque and depth normal" which breaks the rendering. and "before postfx" like the tutorial said which does not render anything. and none of these work when removing the weapon layer from the cameras culling mask like the tutorial said

[lament mango]

weird.. they dont render in the correct order

[pulsar skiff]

hey chat, is there a way to make a light look the same in every scenario? i have this point light that i use as a flashlight but in some scenes it looks dark in dark areas, dark in bright areas and some scenes it looks very bright everywhere

[pulsar skiff]

maybe a script to change the light intensity in different exposures?

[shrewd moon]

To make the light look "the same" you'd have to disable automatic exposure

[latent mulch]

Hello! In this image, the top version is from Blender (eevee), and the bottom version is Unity 2021 LTE HDRP. Despite the obvious differences, the only one I take issue with **is the shading on the left+down wall/shelf. **It's much smoother on Blender. Is there a way to approach this level of smoothness in HDRP? Maybe a shader or lighting parameter hidden in some pipeline settings?
Some details:
Both lights are sun/directional, hitting directly from the front, rotated 10 degress downwards. The light angular diameter has no effect on this shade.

[steel meteor]

The shadow on the Blender image looks like ambient occlusion to me. You can add SSAO (Screen space ambient occlusion) as an override to your post-processing volume and play with the settings in there.

If the light is coming directly from the front then you can also add a Shadow override to your volume, but first try adjusting the Angular diameter of the directional light to give your shadows diffuse edges.

[dawn sorrel]

If the back wood plane is seperated from the vertices of the rest of it you may want to connect them, thats the sort of thing that causes light leaking in engine, so i'm guessing the same may apply for shadows too

[ripe quail]

Are you aware if there's a way to render UI via custom pass after post process, as to avoid needing multiple cameras?

I tried to set it up, but it looks like my UI is still getting caught up in the motion blur.

Oh wow, I got it to work... nevermind! Custom Pass ftw!

[bold wadi]

Hey everyone. Is there a way to have a sky like this :

But

with an exposure like that ?

Im trying to have really dark shadows/areas, but by doing so, the sky is not realistic

[ionic flame]

anybody know a tip for making the ray tracing less laggy

and also how to use emissive lighting with ray tracing

[glacial fossil]

It would be very unrealistic if the sky was this bright and the building were as dark as in the second picture. I think the sky looks good on the second picture as well

[bold wadi]

Oh? Alright then I'll think I'll keep the sky dark as well, thanks for your feedback ^^

[dawn sorrel]

Oh sorry nvm

[summer glacier]

Yes, create a new post process volume with visual environment set to static, and your HDRI, assign it in lighting environment tab

and have another post process volume but set to dynamic, with sky set, and added to hierarchy. That way you can control the lighting and sky visuals separately.

[untold copper]

I know you can use the local volumetric fog component to create additional fog that gets added to the global fog, however is there any way to subtract fog from a region instead of adding? My situation requires that the global fog is quite intense but certain areas need no fog. As far as I can tell, this doesn't seem possible for some reason.

I would rather not create my own volumetric fog, but I'm starting to lean in that direction

Nesting local volumes inside of each other is also additive, so I can't override a region of local fog either.

[digital spire]

Suddenly, there are multiple GI solution that is about to hit asset store at the same time

H-trace, Erabus, Lumina and another one in URP forum

Idk what to choose 😂

[scarlet hull]

What about having a not dense fog in the volume settings, but use local volumes to raise the density around the "hole" ?

But in the future it will be possible to subtract density

[rose ferry]

What is the difference between a "sky and fog global" volume and a "global" volume?

[untold copper]

Sadly this wouldn't realistically work for my case as the area that requires no density is dynamically moving and rotating, and there are multiple different areas that will be like this. I am happy to hear that it's a plan for the future though.

[digital spire]

Only name and the volume scritableobject inside. Just to separate the sky volume and other things shadow, exposure, post effect etc so they are easier to manage

[leaden quartz]

does anyone have best quality settings for shadows (for a pre-recorded cinematic movie so idc about performance)
with me trying to find the best settings they either appear too blurry, glitchy, flicker, etc

[leaden quartz]

also i have a problem with volumetric fog sometimes i can see those square/rectangle shaped holes

[digital spire]

Maybe shadow distance is too large. Try reducing those.

[hoary meteor]

Hi guys, why there is strange problem with lights?

[whole fossil]

guys, is it possible to extend hdrp with custom volume overrides? I would like to change some of my custom system parameters (for example camera parameters) and interpolate it the same way as the volumes are interpolated.

[shrewd moon]

I think you can make your own volume components
https://docs.unity3d.com/Packages/com.unity.render-pipelines.core@12.1/api/UnityEngine.Rendering.Volume.html

[whole fossil]

oh nice! thanks!

[whole fossil]

hm, it seems that it should be possible to create new VolumeComponent with VolumeParameters. Sadly creating one with just test float volume parameter breaks the rendering

[scarlet hull]

It should totally be possible.
I did play with custom volume components myself and didn't have issue. What did you do ?

[whole fossil]

I haven't played with it too much, i've just created component wit VolumeParameter<float> but I think I've noticed in the source code that it shouldnt be used directly, instead we should extend it so it doesnt have a generic type. I'll fiddle with this a bit more first

[scarlet hull]

iirc, you just have to use 'FloatParameter'

[scarlet hull]

https://docs.unity3d.com/Packages/com.unity.render-pipelines.core@14.0/api/UnityEngine.Rendering.FloatParameter.html
There's a lot of other types

[whole fossil]

thanks! I am starting to get it going. One thing that I cannot wrap my head around for now is to detect entering/exiting from the volume. Is it something that is prepared?

[scarlet hull]

You need to update and get the current volume stack result using the volume manager : https://docs.unity3d.com/Packages/com.unity.render-pipelines.core@14.0/api/UnityEngine.Rendering.VolumeManager.html

How do I publish HDRP project. It throws me an error when I try to publish it with OpenGL.

Not possible
OpenGL doesn't support many of the features required by HDRP
Even with URP and BiRP it struggles in some situations

[hardy wyvern]

How do I publish HRDP projects?

as a desktop executable

[hardy wyvern]

What kind of package do I need for it?

[shrewd moon]

No package
A build support module which matches your OS

Bump ^^
Thanks to whoever finds any solution

[bold wadi]

Did you make a volume? If you did, try increasing or decreasing the exposure

[hardy wyvern]

I published Linux, Mac, PC standalone build, but it required unity for others. If I want to create a file for people who play on windows then do I have to take Universal Windows Platform build instead of the first one?

If you want to make a windows build you'd choose the windows build support module

Last time I made bullet hole decals I used the HDRP decal projector, but I'm wondering if it's cheaper and smarter to just use a plane with a texture on it (for walls and other static objects)

With a bit of height to it to avoid z-fighting

[shrewd moon]

I imagine it would be, given the limitations
But to know exactly if the savings are worth it you'd have to profile their performance

[chilly raven]

[sinful imp]

I'm currently having an issue where in the editor, the lighting from my directional light works just fine. However, when I build the game, it's like the scene has a giant shadow casted over it. Here's an image of what I'm talking about (top picture is in the editor, bottom is in the build). I've tried making sure the rotation of the directional light is correct in the build, using deferred rendering instead of forward, changing the light layer of the light, changing all the light parameters, and increasing the max distance for shadows in the shadow post process component. Only changing the max distance for shadows has had any effect, though it's still quite broken. I'm kind of stuck now, so any help is greatly appreciated!

[inner palm]

i went from 2022.1.2f to 2022.1.17f and now none of the skinned meshes are rendering

only when I enable ray tracing, they appear when I turn it off

and its only the skinned mesh renderers

putting the materials on standard mesh renderers works fine so I assume the materials arent the problem

unrelated issue with the janky blur but its only in the scene view and im basically done with what I made this project for

looks like i gotta try my luck with a beta version or seomthign

restarting editor changed nothing

[inner palm]

2022.2.0b8 fixed it

though weirdly the ray tracing is behaving differently now

oh they added denoising???

[loud leaf]

Ray tracing denoising has always been there, for path tracing it is relatively new yes

[modest merlin]

anyone knows what can be causing the shadow being like that ? I've check shadow resolutions lights and didn't work 😕 https://i.gyazo.com/306404bb8ec7886747090978bda0ca30.mp4

[scarlet hull]

Looks more like light issue : Do you have a lot of lights in the scene ?

[modest merlin]

No, I removed 8 now and still

strange 😕

[scarlet hull]

Can you show the inspector of one of those spotlights please ?

[scarlet hull]

Hum, nothing suspicious here either ... But what you show definitively looks like a tiled lighting issue

[modest merlin]

looks like it was because of the shader i was using for a plane to create elevation

[scarlet hull]

Wut :/

What shader was it ?

[modest merlin]

a custom shader

using amplify

[glacial fossil]

That really seems like a problem with per tile light limit or something like that

[scarlet hull]

No, solution is found a bit higher 🙂

[scarlet hull]

What special thing is the shader doing for elevation ?

[modest merlin]

vertex offset from a bumpmap

[scarlet hull]

This is something very straightforward and should work 🤔
Might be interesting to see if it does the same in shadergraph

[glacial fossil]

I saw but I still think it has to do with lighting tiles. Those tiles seems to follow brighter areas very clearly

[modest merlin]

yeah, the problem im the worst in shaders 😅 it will be pretty hard but lets see if i get somewhere

[modest merlin]

Where can i find the lighting tiles limit ?

By disabling this option on the shader gameobject completely solved the problem

@scarlet hull

[scarlet hull]

????
This would mean that the issue is related to motion vectors, but it really doesn't look like it would have something to do with it :/

[modest merlin]

Im really confused with all of this, being honest 😅

[wanton shuttle]

On a material using the HDRP/Lit shader... Why does modifying the emission not actually change anything during runtime? If I look at the material in the inspector, nothing changes. However, if I go into the inspector and change the values manually, it changes.

Code snippet.

   m.SetColor("_EmissiveColor", Utilities.GetColorFromTeamColor(owner.teamColor));```

[dawn sorrel]

help me decide between urp or hdrp please... my game is going to be on a computer but i dont know which to choose.. i know that hdrp is stronger... but I am not sure which to pick

[summer glacier]

If you don't know, and your a beginner, probably better off with URP. Even better, built-in

most videos are built-in.

[dawn sorrel]

yes but i want to create shader graphs now.. i did work with materials in the normal shader... but now i want to add stuff.. i just dont know which to pick

[dawn sorrel]

I will listen to your advice... ill URP
thank you 😄

[summer glacier]

You can move into HDRP later, now is just learning

[dawn sorrel]

one last question though... just asking for your opinion, if you work on a game, which would you rather finish first the mechanics or the effects

[dawn sorrel]

sure thing !

[summer glacier]

effects? do you mean visuals

[dawn sorrel]

yes

[summer glacier]

You don't have to finish one before the other, they usually go together but it's good to focus on mechanics, visuals can be done later based on what you have

[dawn sorrel]

I understand what you mean, thank you

and that's what i did.. i finished most of the mechanics part... so time to do some visual stuff

[scarlet hull]

When emission is set to not black on the material, the material inspector will toggle a keyword.
Since you are changing the emission color value from code without the inspector open, the keyword is not set, and the emission code is stripped out.
We now have a public API to automagically set all keyword and passes depending on the material property values : https://docs.unity3d.com/Packages/com.unity.render-pipelines.high-definition@15.0/api/UnityEngine.Rendering.HighDefinition.HDMaterial.html#UnityEngine_Rendering_HighDefinition_HDMaterial_SetUseEmissiveIntensity_UnityEngine_Material_System_Boolean_

Only available since unity 2022.1 sadly :/
If you're on LTS, you need to set the keywords manually, but to make it work in a build you need to be sure that the needed shader variant is included, using ShaderVariantCollection.

Or, here's an easy "hack" : set the emission color to something very close to black but not black, to have the material emission keyword/pass enabled, but not visible ^^

[wanton shuttle]

Got it. Thanks!

Have you enabled Clouds in the HDRP project settings? I haven't used it myself though.

[dawn sorrel]

Yes, I enabled all the Cloud things

[onyx gale]

does anyone know what setting i have to change to add a brightness setting to my game? does unity provide some kind of setting

[dawn sorrel]

Exposure maybe?

It’s a post processing thing

[onyx gale]

yeah that’s kinda what i’m going for now, thanks for the reply.

[strong slate]

how do i increase render distance?

i have plenty of trees, but they arent visable and the shadow map aint showing unless im close to the ground

[fierce ridge]

My bakes are saying they are going to take 8 hours plus, even when done on the gpu regardless of quality settings

Is there anything i can do about this

[keen jay]

In case any help, I wrote a blog post of what I have learnt about lighting so far (still learning!) - e.g. there is the Exposure Post Processing effect, but you can also fiddle with ISO etc on the main camera or Cinemachine Virtual Cameras instead (which is easier to animate). https://extra-ordinary.tv/2022/09/25/lighting-tricks-in-unity-hdrp-for-cinematic-effect/

[keen jay]

Do they appear in the Game window but not the Scene window? There are the camera settings for the scene camera for example. But there is also LOD (Level of Detail) if used by your trees, and main camera also has "Clipping Planes" for near and far you may want to check.

[fierce ridge]

???

[inland star]

what are the shadow resolution settings on your lights? Also, you could turn down the shadow distance if your scene doesn’t need a 6km view

oh bruh they left the server, can’t even ping them now

[shrewd moon]

Do you have a lot of high-poly static meshes in your scene?

[fierce ridge]

i did not, cleared cache and that fixed i't

[crude creek]

hey guys so i just made new project and installed Hdrp

but i get like 40 errors instantly and ive triwed to fix them but i am unable to

https://gyazo.com/792c9cd3586a9eb7f55e0ffd070c4f86

ok well when restarting not so many anymore but

[shrewd moon]

Most of these are warnings unrelated to HDRP, not errors, and the messages seem pretty clear
If the red error about invalid dependencies persists, you'll need to check it for clearer details about what packages you may be missing

[crude creek]

Yeah thats what i did it just says either reimport or check the version of the package is the same as the hdrp and it is did all those things ..

[hearty smelt]

I'm having a terrible time understanding how these HDRP skyboxes work. The global settings seem to take over every scene in the project, no matter what skybox I place in each individual scene. Each scene needs it's own skybox. If I take out the *global * skybox, I get no sky's at all from any scene , even though each scene has their own skybox assigned.

At this point I'd be willing to pay for some help on my project from an HDRP pro who knows how this works, and can make the game more performant. (That's the other thing)

Selecting very low, low, medium, high and very high graphics profiles makes the scene look better, or worse, but has 0 impact on framerate. <shrug>

Any HDRP pro's need a side gig for a couple of days? 🤔

[dawn sorrel]

Why the shadows so weird?

like stretching

[keen jay]

My best guess, each "volume" has a priority. So if you add a global volume, are you giving it a higher priority value? You can check volume priorities in the "Light Explorer" window (the second tab is a "Volumes" tab which shows which volumes are in effect and their priorities). (And no, I am not a HDRP expert - just learning myself at the moment!)

[keen jay]

Under Quality / HDRP in the project settings I got some improvements by cranking up the Punctual and Directional Light Shadow resolutions. I then set the directional light game object shadow resolution to the max as well. It might not be your problem, but it helped a lot on my project.

[dawn sorrel]

The res didnt help sadly

I tried

before

[keen jay]

Well that got to the end of my knowledge pretty quickly! Lol!

[dawn sorrel]

lol its ok

[summer glacier]

It's because you're using high quality filtering for shadows. And by default, the directional light angular paramater (basically shadow smoothness) is set to 1 which is too high.

Reduce it to 0.5 or so. You can find it in your directional light inspector.
Also high filter quality shadow depend on TAA to clear out noise, so in scene view make sure camera is set to TAA and refresh is on. Or you can just ignore the noise in scene view and try it out in game view with camera set to TAA.

Another option is to just switch to the medium shadow filtering quality option, then it'll just work as usual and less complicated. High offers better smooth shadows and a parameter to control smoothness.

[dawn sorrel]

Got it, thanks

[lament comet]

Hi guys! Is it possible to use visual effect graph effects in HDRP + DXR mode?

[shrewd moon]

Post only to one relevant channel please

[west linden]

What is this "DXR

DirectX raytracing?

[glacial fossil]

Raytracing support of VFX Graph is currently undrer In Progress category in the official roadmap

[keen jay]

Just a note that I have given up on TAA as frequently the artifacts it introduces are worse than the problem it solves - I often get a shadow trail behind the character for high contrast shots (e.g. dark character on light background). (I am using 2022.1.)

[tacit kraken]

Im using HDRP for VR and I guess Forward is the way to go. People are also saying that MSAA is the best to use. Do I change that under the HDRP High Fidelity > List Shader Mode: Forward > Multisample: MSAA 4x? I also see it under the HDRenderPipelineGLobalSettings (every rendering tab). Or if someone else had a reccomendation please let me know! Thanks.

[keen jay]

I set the anti-aliasing on the main camera (and the scene camera). (Actually, I tell a lie - I turned off the anti-aliasing as it was giving me more problems than it was solving, but that might just be for my project!)

[summer glacier]

Yeah, HDRP's TAA was very bad until recently. It should be usable now with the ghosting improvement, and the addition of a jitter parameter. Reduce jitter to 0.5, 0.6, should help reduce issues

In 2023.1 alpha, there's some new sharpening quality options that are much better than the current (and only) option

[leaden quartz]

Any ideas why lightmapper doesnt seem to do much if anything at all in HDRP

It does make a slight difference but generally the room looks too bright, especially noticable where the desk is there is no shadow at all

Path traced it looks like this, a bit too dark but thats the look i want to achieve just a bit brighter in the end

[warm forum]

Does anyone have suggestions that might help get me started on a good way to get color variance for things like clothing or metal? Most of what I found involves using MaterialPropertyBlock but I read that is not the way to go in HDRP? I'm not very knowledgeable about this area, but would like to create color variants of clothing and swords and stuff. What should I look into to get me started on the right way to do this?

[strong slate]

why are some dark and some bright even tho i have no light source in the scene?

[shrewd moon]

Ambient light and reflections from the visual environment?

[keen jay]

It took me weeks to discover “ground tint” in the hdrp profile. I could not work out why my characters had a light shining on their faces from below!

[strong slate]

how do i fix? im kind of new to lighting and hdrp

[scarlet hull]

Bake lighting and reflection probes.
I recomand to watch some lighting tutorials.

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

[scarlet hull]

Why not create materials or material variants ?

[strong slate]

ok, im trying to make everything dark and only a flashlight as light but cant seem to find something that specific

but ill check out the video

[scarlet hull]

Try to start with the "indoor scene" instead of outdoor then

[warm forum]

I'm using new materials for each color variant at the moment but wasn't sure what is the usual way of doing this. I thought I'd see what other people are doing and learn something. Does the SRP Batcher make having these extra materials not really an issue when there are quite a few variants on screen? I'm really just trying to see what I need to start looking into to make sure I'll be able to implement a good way of doing this. If just using extra materials isn't going to create an issue down the road that works fine.

[scarlet hull]

Indeed SRP batcher is here for that.

[warm forum]

Ok, that seems like it will be much simpler than I was imagining. I appreciate you taking the time to answer my question!

[loud leaf]

Is there a reason why there have been no HDRP changes for 7+ weeks?

[scarlet hull]

If you are refering to this repository : https://github.com/Unity-Technologies/Graphics/tree/master/Packages/com.unity.render-pipelines.high-definition
This is no more our working repository, we work on an internal repo and changed are mirrored in this public one "regularly".
The process takes time and is tricky, and over this, sadly not automated yet iirc.

[loud leaf]

Yep I know, but it was supposed to sync every 2 weeks, and I noticed it completely stopped, so I was wondering why.

[loud leaf]

Has the inconsistent folder structure and messed up workflow really made things easier?

I can see this helping someone internally who has never heard of symlinks, but for the most of us, this is just terrible.

Not to mention all of the previous PR's and paths that have broken due to this.

Not trying to bash you personally here, by the way.

[scarlet hull]

Erm, it did made some things easier indeed:

• The graphic packages are now in the same repository as the c++ source code, resulting in less breaking changes from c++ code in graphics
• It's also way easier for dev to work on a feature that requires c++ and c# code change
• We now bound the graphic packages versions to the engine release, making it impossible to have a broken engine and package version combo

[loud leaf]

It would have been better to prepare the automated synchronization with the public repository before such a massive change that affects all of us working with the HDRP codebase. This change has not only been executed in the wrong order (execute and then get ready), it has been 8 months and is still not ready. We're all left in the dark trying to ensure compatibility with the next release and it's almost scary waiting for massive dumps of squashed together PRs/commits without any of their original structure and messages, especially if we're getting 8 weeks instead of the original 2 weeks worth of data.

[scarlet hull]

I think it's not the first time I see this feedback here ...
We are working to have an automated process and more frequent updates.

[loud leaf]

Indeed, and not even from me. I decided to not speak up until now, trusting things would improve without the need to raise concern. Apparently we didn't deliver enough feedback last time such a workflow disrupting change was delivered to the SRP community (december 2020) since we were greeted with current broken circumstances due to bad preparation only a year later.

[keen jay]

In case useful, I have been keeping notes in a blog. Turning ground tint off for example helped a lot for dark scenes for me. https://extra-ordinary.tv/2022/09/25/lighting-tricks-in-unity-hdrp-for-cinematic-effect/

[dawn sorrel]

@loud leafglad to see you back mate 🙂

[dawn sorrel]

its internal now 😦

[whole fossil]

guys, I am really bad at shaders and got stuck with the rendering outline of occluded objects based on https://github.com/alelievr/HDRP-Custom-Passes. I can't figure the way to render outline only when it is occluded. The objects are being rendered to the custom buffer but the place where outline is being drawn doesn't exist yet in the depth buffer so I cannot compare it to anything. Does anyone have an idea or stumbled upon such thing?

[scarlet hull]

I did this sample originally 😄
Haven't touched or even looked at it for a while, but iirc in the "selection fullscreen" shader, there are a lot of samples for drawing the outline.
You'll also see a depth comparison for the "fill" effect.
To draw only the outline of culled parts of the object, you can add a depth comparison for each of the samples, and it should be good.

[whole fossil]

yeah for fill effect it is pretty understandable for me as those pixesls exists in the custom & camera buffers

apart from that - I really appreciate your work, thanks ❤️

[whole fossil]

so the problem is that I can't compare depths at given position because in the custom color buffer where objects are being rendered to there is no depth information (as the outline is rendered "outside" of original object), right?

actually, I have achieved what I've wanted, but I doubt that it is a correct way:

        float4 outline = float4(0,0,0,0);
        
        float2 uvOffsetPerPixel = 1.0/_ScreenSize .xy;
        float customDepthSample = 0;
        
        for (uint i=0 ; i<sampleCount ; ++i )
        {
            customDepthSample = max(SampleCustomDepth(posInput.positionNDC + uvOffsetPerPixel * _OutlineWidth * offsets[i]), customDepthSample );
            if (customDepthSample <= db)
            {
                outline =  max( SampleCustomColor( posInput.positionNDC + uvOffsetPerPixel * _OutlineWidth * offsets[i] ), outline );    
            }
        }

where

float db = LoadCameraDepth(posInput.positionSS);

[scarlet hull]

Well, if it works 🙂

[whole fossil]

yeah, it works as it should. I mean that I've made something that works but my modifications probably arent the wisest ones 🙂 I don't like to fiddle with stuff that I don't understand decently at least ^^

[strong slate]

hi, could someone jump in a call with me quick? i need some help setting up some basic lighting

[true zealot]

https://resources.unity.com/games/the-definitive-guide-to-lighting-in-the-high-definition-render-pipeline-unity-2021-lts-edition

[strong slate]

nah bruh that aint gon help

[strong slate]

sucker

[shrewd moon]

Keep it appropriate and on-topic, please

[strong slate]

ok 🥸

[dawn sorrel]

It was actually 2.5 by Default which is definitely WAY TOO much, 0.05 or lower is good

[dawn sorrel]

How do I get rid of this effect (Light becomes dimmer and lighter)

[keen jay]

Have you tried using a "local volume"? You can define a volume that kicks in when you enter a region, where that volume could say change the camera exposure so everything looks darker.

oh, sorry, you said "get rid of" - I just read "get". Are you using automatic exposure? There are a few modes to it. I would try adding an exposure global volume where you set exposure to "fixed" just to see if it stops happening.

[dawn sorrel]

I am not using exposure in my volume

[keen jay]

I am suggesting to try adding one, as the default may be automatic exposure which does a histogram of the screen. When you pan out, you see all the dark around the area, so it may be overcorrecting. To see if this is the problem, add a Exposure post processing effect but set it to "Fixed" (not automatic) just to check that is not the problem. (It was a frequently problem for me, so I set a global Exposure with mode set to "Physical Camera" so the ISO etc of the camera controlled exposure.)

[shrewd moon]

Automatic exposure attempts to adjust to the void outside, making lights appear brighter
This does not happen in game assuming there player doesn't also go out into the void

[summer glacier]

i suggest switching to medium filtering. High filtering for point light shadows has a very large cost.

[dawn sorrel]

@summer glacier @shrewd moon @keen jay Thanks guys, I understand now

[fierce ridge]

just wondering what causes unity to have models break when i import them

[slender sorrel]

hello

im investigating volumetric clouds

but for some reason, it didt work in game, but work on scene

how can i solve this?

[keen jay]

Random thought - could you have two volumes with same priority? It might randomize which one wins then. (Solution would be to adjust priorities of the volumes to different values.)

[slender sorrel]

but i only have 1 volume in this scene ;/

[keen jay]

Looking at image, is it something like the amount of light on the clouds, rather than the clouds themselves at fault?

[slender sorrel]

sorry but I dont quite get what u mean

[keen jay]

Its okay - it did not make sense when I thought about it either! 😉 Its just the brightness of the two windows is different and I was trying to think of why that might occur

The point of viewing the clouds is different, at a different angle I think.

[slender sorrel]

i set the camera to the scene's camera position by ctrl + shift + f

[keen jay]

A suggested thing is to select the camera, then "Align View to Selected" so the scene camera exactly lines up with the main camera.... (but bottom line is I am not sure. They are close, but not the same)

Great minds think alike!

[slender sorrel]

lemme try..

[slender sorrel]

i had aligned the view to the camera

but seems the same

[slender sorrel]

any possible way to make 2 window's brightness the same?

[keen jay]

I was just experimenting with one of my projects, and the scene and game view window clouds are not identical either...

[slender sorrel]

🤔

[slender sorrel]

at least ur cloud is working 😃

[keen jay]

I had to adjust the field of view of the scene camera, but yes - its in both.

[slender sorrel]

ooh, i just fixed that.

i turned on local clouds

thats why it didt show up in game view

i shouldnt turn on something that i dont even know

[keen jay]

Cool! Glad you worked it out. I had no idea otherwise. Local Clouds I think let you fly through them (like a plane).

[slender sorrel]

ooh

thanks for helping me btw 👍

i appreciate it

[keen jay]

No problem - I am trying to learn it all too. I often find debugging problems helps me learn more too!

Local clouds definition: "Indicates whether the clouds are part of the scene or rendered into the skybox. When enabled, clouds are part of the scene and you can interact with them. This means for example, you can move around the clouds, clouds can appear between the Camera and other GameObjects, and the Camera's clipping planes affects the clouds. When disabled, the clouds are part of the skybox. This mean the clouds and their shadows appear relative to the Camera and always appear behind geometry."

[slender sorrel]

O.O

graphics rendering are just getting better and better these days

[keen jay]

...and more and more complex!!!

[slender sorrel]

ye

[limber crypt]

trees. how.

holy shit does speedtree not work

it's OK till the bark, then when the leaves come in it gets so, so, fucked

[timber pollen]

HDRP "the current render pipeline does not support grass details". Can't paint on my grass. Is there any way around this or should I do with hdrp? Ty

[dawn sorrel]

You can use the tree details, if you're talking about the default terrain system, it still works.

[summer glacier]

terrain detail for HDRP supported 2021.2 and after

use tree details (not good for performance), or use an asset that handles terrain object rendering (GPU instanced, nature renderer)

[keen jay]

Are there good assets for trees and grass with hdrp? A lot of my assets did not upgrade to hdrp, meaning all my terrains now look rather bleak and empty.

[wraith blaze]

Hey guys dumb question but is there anything similar like unreal's lumen in hdrp?If not is there any 3rd party asset that can work with hdrp that provides this feature

[scarlet hull]

No.
You can find some real time GI plugins compatible with HDRP in the asset store, like this one : https://assetstore.unity.com/packages/vfx/shaders/fullscreen-camera-effects/lumina-gi-hdrp-real-time-voxel-global-illumination-231711

[wraith blaze]

Do u know if the performance hit will be bad?
