Hi! I am trying to create a feedback/fluid effect in shadergraph. I need to have one of the subgraphs to output a texture that can then be sampled by other subgraphs. I can't seem to find a way to do that. Is there a way? Are feeback/multipass shaders possible in shadergraph?

[fluid merlin]

Yeah, there's something weird at play with a volume and an override not taking effect correctly. If you have two volumes and one uses a physically based generated sky and the other volume changes the sky to HDRI, it won't correctly adjust the sky. This basically impacts lighting when moving from an outdoor lit area into a darkened interior, if you need full 100% black darkness, you have to change from PB to HDRI with exposure 0. So if you change the weight from 0 to 1 on the volume with the HDRI sky (with a higher priority), it won't change the sky. What seems to work is keep the GameObject that has the override volume disabled (not the volume component). Have the volume component set to 0 weight, then enable the GameObject, then Lerp the weight from 0 to 1 on the volume weight. This was the only solution matrix that worked for me. It seems to be an issue with 2021.3.1f1 & Cinemachine 2.8.6.

[eternal laurel]

Hmm what is happening to us is that we are in a local active volume but we shift the whole thing, player included a bit and then the local volume stops registering for some overrides

[primal gazelle]

Custom Render Texture is not an option in hdrp the 😔

[minor sedge]

I finally got the raytraced reflections right! In case anyone else comes looking here in the future with the same problem, check the aspect ratio of your scene camera viewport. It needs to be at least 16:9, there is a fixed culling angle for the lighting that does not get adjusted to match taller aspects.

I was pulling my hair out going through the HDPR settings and documentation for hours looking for a setting that had an effect on it, but there isn't. It's just hardcoded for 16:9 and I had to find out the hard way, I hope this can save someone else the trouble.

There are still some objects like the lamp shades randomly missing from the reflection though, if anyone can shed some light on why that might be I'd be all ears.

[minor depot]

That really feels like a bug

[eternal laurel]

am I stupid or did hdrp use to have a built in texture packing tool

[scarlet hull]

With the material converter, it is still there, but there is no editor UI for the texture packer

[eternal laurel]

Is there a plan for one? I really think there should be one

[scarlet hull]

No plans afaik

[dawn sorrel]

So, I'm trying to create godrays, and right now all I have is volumetric fog, but this makes the whole scene foggy, any workaround?

[dawn sorrel]

Sun shafts are what i'm looking for, I found a forum post refering to the forest demo which had it, but it seems to be gone

[fluid merlin]

You have to adjust your base and maximum height on the volumetric fog. This is a bit of an older video but covers setting it up and troubleshooting fog. Also, turn on Show Additional Properties for fog as Anisotropy is now hidden.
https://www.youtube.com/watch?v=OrOmoVXoOEU

[dawn sorrel]

So, I can't really get it to look like that for some reason, I can get rough god rays, on huge mountains and such, but on small objects, like leaves, it doesn't really do anything

I have that forest scene as well, and still can't figure it out

also, my shadows are very very dark, how can I fix that?

[dawn sorrel]

Figured it out, it's local volumetric fog, paired with the override

Shadows are still dark as hell, and I need to add lots of local fog to get it to fade correctly, but its better

What I've been doing thus far for shadows is just to change the Tint on the shadows, this helps, but it still makes the shadows very dark, you can tell the texture is unlit.

[fluid merlin]

Yeah fog is tricky, there's lots of on/offs with it...
Shadow darkness can be tricky. There's lot of adjustments for it, like dozens. Big ones to check:

• Indirect lighting controller
• Micro shadows (opacity setting)
• Contact shadows (opacity setting)
• Ambient Occlusion (intensity)
• Light -> Shadows - Additional settings (Tint)

[dawn sorrel]

Okay, first off, I don't have the Indirect Lighting controller, I have seen it in projects, but didn't think it was super important, what's it do?

I found it, and see what it does, very useful, but strangely does nothing in my scene

I have the forest environment and my scene open, tweaking it does stuff in the forest one, like boost the diffuse, but nothing in mine when tweaking the same

Possibly because Enviro 3 is managing the lighting

[fluid merlin]

Ah, yeah enviro does funky stuff... including eating lots of CPU cycles 😄

[dawn sorrel]

Oh, and the Micro and Contact shadows work beautifully, its shadows on other objects that are funky

[dawn sorrel]

Yeah I've already had to debug a few weird things, it's not to bad at all however once I disabled broken stuff

9ms on CPU and GPU, from 8 on both, while using particles

and controlling the Directional Light

No idea why that Indirect Lighting Controller won't work either, I can have Enviro manage it, or disable it, and regardless it doesn't work... Unfortunate since it seems to be what I was looking for

[fluid merlin]

Usually what I recommend is making an empty project, sticking the "Unity Terrain - HDRP Demo Scene" in it and then troubleshooting between the two projects. It's extraordinary difficult to get high performance and high quality in the same quadrant with Unity without reference examples. I usually use the Unity projects or other assets and then copy over the volume overrides into my own projects. Otherwise, you'll spend a year fiddling with settings

[dawn sorrel]

God damn

that's the scene lol

Also, I see that it works well, but I still cannot figure out why the hell its dark

[fluid merlin]

Yeah, Unity, engine wise is heavily pointed towards lowpoly stylized games versus realistic genre games. Which has been sort of problematic in HDRP, one because you can't use highpoly objects natively and for HDRP to look good, you need 4K textures. So the whole "optimization" workflow for realistic scenes starts taking on a new life of "how can I improve lighting, shadow, volumetric, etc... performance?" so that the games are actually playable.

Not sure what's causing your super dark shadow darkness after looking at the usual suspects, my best guess is something around ambient lighting. In your project if you open up the template scene, are shadows really dark in it? If so, it's probably something in your HDRP/quality settings for the project. Otherwise, it's something in your scene and in that case, you might want to copy over a volume config from something else with good shadows and use a new directional light.

The other thing you can try look at that just occurred to me is the camera settings, try a new camera. A lot of the "physical camera" settings can have an impact on ambient light and other frame setting configurations specific to the camera.

[dawn sorrel]

Strangely to, when I fixed the Indirect Lighting Controller, I would have to boost it and wash out the whole scene before the back of objects would look correct

Seems like there is no ambient lighting whatsoever

Doesn't look as bad now that i've made the shadows on the ground lighter, but man is it dark on the back of objects

[dawn sorrel]

Loading the scene, the shadows aren't to bad, both scenes are loaded here, some weird artifacts, but that's to be expected

It's especially strange that the shadows are fine in the Forest Demo Scene when loaded alongside my scene, but the shadows in mine are still bad

In fact, it screws up my scene more lol

These shadow cascades are really weird

This is all in editor, so it can't be the camera, yes?

I disabled everything in the Forest Scene, only the Post Process, Sky and Fog, and Directional Light left, the only thing contributing is exposure, everything else is secondary

Yeah, it's something in my scene, all the shadows get messed up now if I load my scene

[fluid merlin]

Well, at least you've narrowed it down 😅

[dawn sorrel]

Yeah, it's very annoying, it's absolutely Enviro 3 at this point, copying all the exposure settings gets me nowhere, How does the visual environment and sky effect the ambient lighting?

[fluid merlin]

Depends on the sky type, so with HDRI, there's an exposure value for it, high exposure will flood the scene with light and wash out shadows, etc

[onyx lark]

do y'all have an option in your games to switch between forward and deferred rendering?

one friend mentioned that he got better performance in another game with forward rendering (and that my deferred-only game is running at an awful framerate)

i am currently waiting to hear back if switching does anything for his performance

it certainly cranks up the size of the build. i just compiled a lot of shader variants.

[hearty peak]

It would cause the art team to think differently about many things, probably to the point of making different prefabs/scenes for the different pipes. It would make some sense if you want the same project to run on ps5 and a midrange phone. But extra work ensues. I’ve never had a project that did target such a wide performance band.

[onyx lark]

Oh, this isn’t about covering a very wide range of perf

In this case, I was just interested to see if Forward rendering would magically give my friend more frames (it added 1 frame).

they’re using an older gtx 940(?) on Linux

[fluid merlin]

No, this isn't the magic performance switch you're looking for. HDRP is targeted towards higher end desktops and consoles. For that hardware, you're probably going to get better performance on the Standard or URP pipeline. Unity's old way to guidance on this has been that if you have a single directional light, use forward, if you have lots of lights in your scene, use deferred. Unity has a page dedicated to this forward vs deferred topic: https://docs.unity3d.com/Packages/com.unity.render-pipelines.high-definition@14.0/manual/Forward-And-Deferred-Rendering.html

[onyx lark]

I wasn't really expecting it to work, ha :p

[fluid merlin]

[onyx lark]

they just had an anecdote from another game that apparently ran way better with forward rendering

i figured it could be something specific to their hardware. or just gremlin. mystery.

[onyx lark]

thanks, though! I had a rough idea of which to use, but this is way more concrete

[fluid merlin]

On that hardware it's not even worth going through the optimization guide tbh....

https://forum.unity.com/threads/mega-runtime-performance-tips-thread-unity-hdrp-guide-to-better-runtime-unity-performance.1169837/

[onyx lark]

i wonder if that game happened to have just one big directional light

it was an outdoor driving game

I am loooking to add more graphics options to my game. I currently just let people switch between the three big low/medium/high presets.

[fluid merlin]

There's 10k reasons why a game could be running slow from a dev perspective. The usual reason for a player endpoint is hardware, but from debugging and developing, it's usually shadows, too many polys in camera, both of those things together, and using way too much code in Update() for everything and anything.

[onyx lark]

(notably, an option to just turn off realtime shadows entirely)

[fluid merlin]

Yeah, realtime shadows is a massive pull on cpu. The fewer the better...

[onyx lark]

not sure if i'll need to set that every shadow-casting light, or if there's some global switch i can flip

time to stare at the custom frame settings

[fluid merlin]

There's a Light Explorer to make it a little easier (Window -> Rendering -> Light Exp)

[onyx lark]

ooh, neat, didn't know about that one

[fluid merlin]

It can take a long time to optimize, when I started in HDRP, I was getting 12fps, I'm now at around 200fps

Check out the above guide, there's some good stuff in there

But that GPU/Hardware is also 7 years old, so that's going to be a massive limiting factor too.

[onyx lark]

Yeah. I’m not expecting their system to run it well

But I do need to start doing some genuine work to clean things up.

[onyx lark]

oh no i have so many shadow draw calls

this scene isn't wildly complex

this stuff is fascinating. i'm getting a rough handle on what's going on here

some of my geometry isn't showing up in the frame debugger when i select what's clearly the relevant draw call (the shader is only used on one specific object). bit weird.

[fluid merlin]

Things to help on the shadows:

• Change lights to baked, enable baked shadows. Bake lighting.
• For realtime, use fade distances for shadows & the light itself
• Use cookies for lights in place of shadows
• Limit shadow cascades to 2 if possible, especially for outdoor scenes with vegetation
• Don't use shadows on point lights if possible, use spotlights if you can
• Directional light shadows are intense and eat a ton of cpu, if possible avoid.

[onyx lark]

i made a gore system kind of like l4d2's

it's rendering shadows for the entire skeleton at all times 💀

the most appropriate use of the skull emoji possible, i think

i need to just turn those meshes off completely when they aren't needed

[fluid merlin]

Change the layer, to one culled by the camera, it's cheaper in performance

[onyx lark]

interesting, will examine that.

I also see two dozen draw calls for the body. I have two dozen skinned mesh renderers on this character, because I haven't merged them all in blender.

I guess those ain't batched.

[fluid merlin]

Skinned mesh renderers are they're own pain points, often due to multiple materials per mesh.
Turn off shadows on the meshes that don't need them, for example, if there's a body & armor, turn it off for armor.
Turn off shadows for any hair card/mesh if you can, those can really drag down the renderer

[onyx lark]

fortunately, it's just one material for everyone

is there any way to gauge how "expensive" each draw call is?

I don't see anything obvious, like a duration

[fluid merlin]

It's mainly looking at frame debugger and other optimization tools. There's a lot of youtube videos on optimization with the profiler. If I'm not mistaken, I feel like Unity did one recently

[onyx lark]

it sounds like you mostly just aim to reduce the number of calls

interesting: part of the character model is now getting SRP batched, and part isn't!

[fluid merlin]

Yes... in general unity optimizing is "reduce everything"... lights, shadows, polycount, effects, physics, anything moving.

[onyx lark]

ah, material property blocks prevent SRP batching

i suppose that you're meant to just create many materials, rather than using property blocks?

[fluid merlin]

SRP batching has a lot of requirements and sub requirements, overall same shader/same properties

There's like half a dozen major requirements for SRP batching

[onyx lark]

yeah, switching from blocks to just directly modifying the materials (which instances a new material for each renderer) gets everything into the DrawSRPBatcher category

one big ol' batch

(definitely need to turn the skeletons off..)

[vital gyro]

How do I enable SSR for water
and fix those strange lines in the reflection on image 1’s plane

[scarlet hull]

Did you enable SSR on transparent ?

[vital gyro]

Yes i think so
And reflections only appear at 0.9+ smoothness for some reason
Are there more specific configs for jt?

[scarlet hull]

This is expected as it is the default settings for SSR :

[vital gyro]

Thanks I didn’t find this thing

[onyx lark]

this is gonna be a vague question, but

when looking in the frame debugger, I like how things look more before the last few post processing steps

the colors change significantly and the brightness goes up a fair bit

i thought it was happening in UberPost, but then I'm pretty sure it started only happening in that final blit step

...I'll go investigate this some more first. this is unusably vague, haha

[harsh basalt]

You need to enable the transparent ssr on default camera frame settings also. Adjusting the refraction parameter on the water surface may help to resolve the hard edge underwater.

[twilit swift]

Hi, when I deactivate the lighting the scene view goes extremely slow, but when activated again it goes pretty well, someone knows what could be the issue?

Ping when reply please.

[vital gyro]

thanks i got it working
do you know how to fix this?

[harsh basalt]

because unity needs to recompile the shader when you switch to unlit mode. Wait until the compilation finishes the performance will be back.

[twilit swift]

No, it compiles and still does that.

[harsh basalt]

That's because there are not enough samples for ssr. Try to increase the sample count.

[harsh basalt]

Are you sure about the progress bar for the shader compile is finished?

[twilit swift]

Yes.

[harsh basalt]

In that case you need to use profiler to check what is going on.

[vital gyro]

thanks again
set the quality to high, still a bit left but much better

[loud leaf]

Does anyone know of a guide/tutorial to use Nsight to debug HDRP DXR in editor? I don't want to create standalone builds while debugging. It seems like tutorials are hard to find.

Basically any good tool will do, RenderDoc seems to break the output, no errors, just doesn't match the original output (?) Edit : RenderDoc issue seems to be ray tracing related, probably unsupported so it falls back to screen space which is making the output worthless in this case

[scarlet hull]

There is a limit about what SSR is able to reflect, you can increase the number of steps and the distance, but as some point if the rays get offscreen they will inevitabely fall back to the sky or the "closest" reflection probe.

[vital gyro]

Ik

I was talking about the artifacts of SSR when you get too close

[tacit dock]

HDRP eye candy (with APV on)

[fluid merlin]

Looks good... was that with raytracing?

[tacit dock]

Mixed lighting with the new adaptive probe volume

Directional is real-time and GI is baked

I suggest you try the new APV, it's super cool!

No lightmap UVs and fast bake time

[loud leaf]

Any ideas on how to tackle this? I've disabled Strip Runtime Debug Shaders in my HDRP Global Settings, and added #pragma enable_d3d11_debug_symbols to my shaders, but no success.

[marble needle]

anyone know how to stop the transparent bit of this material from reacting to shadows & light?

[dawn sorrel]

This is what I'm talking about, there is no fog at all, but they have godrays through the leaves and clouds

I need a solid amount of fog to get the same effect

[fluid merlin]

As far as I know in unity, the rays are only generated through volumetric fog. The light shafts in UE are much stronger because.... UE has bloom specifically for the lightshafts alone, Unity does not, so you have to amp up the fog in Unity and the intensity of the light and the intenstity of the volumetric light in unity to make them show. Sadly, the quality of the ray on is hugely non-performant to reduce the noise size in Unity.

[dawn sorrel]

Damn, that sucks, this is Cryengine as well, so I thought it was probably a engine specific thing

[harsh basalt]

There is fog if you look closer

[dawn sorrel]

Nowhere near what I need however, this is what I have

behind clouds

[digital spire]

isn't there like a volumetric multiplier in the light?

[true zealot]

You should be using Cutout on your material. I am not familiar with HDRP's materials but in the default render pipeline if you have it set to Transparent, transparency is lit by reflections and lighting/

[digital spire]

oh hey, I just tried it, try increasing the anisotropic of volumetric fog

[harsh basalt]

You need to enable the shadow alpha clip

[marble needle]

TYSM

[minor depot]

Link to the effect? That's pretty interesting, I wonder how it's implemented

[fluid merlin]

In UE? https://docs.unrealengine.com/5.2/en-US/using-light-shafts-in-unreal-engine/
I wish Unity had this for godrays/light shafts.... because the anisotropy in Unity fog can get really bad without high performance settings for it.

[minor depot]

From what I gather the first method is pretty similar to unity fog, and the second is more or less a radial blur?

[fluid merlin]

probably yeah. I sometimes run into the same issue as rwxr-xr-x where you have terrain at different levels and need light shafts and the fog is inconsistent at various elevations. Usually have to use local volumes which can be a pain

[onyx lark]

you could use alpha clipping, so that nothing renders at all

that seems appropriate, given the pixely look of the texture

You are seeing a bit of glare because of the smoothness

[dawn sorrel]

yeah, I was already using an incredibly high anisotropy value, so I think it's as good as it's going to get unfortunately

[modest heart]

Does HDRP not support grass textures on terrain?

[hexed turret]

Hello everyone, has anyone worked with water system scripting in HDRP 15+?
For simulating buoyancy, you need to query the water surface's height using FindWaterSurfaceHeight(WaterSearchParameters, out WaterSearchResult) as per the documentation (https://docs.unity3d.com/Packages/com.unity.render-pipelines.high-definition@15.0/manual/WaterSystem-scripting.html).
However, that function is not found in WaterSurface's documentation page, nor is it recognized by Unity in HDRP 15.

[eternal laurel]

How the f do you set emission intensity from a script on hdrp 16

[hexed turret]

Fixed it. You should replace:
targetSurface.FindWaterSurfaceHeight(WaterSearchParameters, out WaterSearchResult) by targetSurface.ProjectPointOnWaterSurface(WaterSearchParameters, out WaterSearchResult)
searchResult.height by searchResult.projectedPositionWS.y
searchParameters.startPosition by searchParameters.startPositionWS
searchParameters.targetPosition by searchParameters.targetPositionWS

[eternal laurel]

Docs says mul color by intensity and set that but thats for 12 and doesnt work

Im this fucking close to making a shadergraph for this

[fluid merlin]

The doc on this sucks tbh... so the way to do this.

First check if HasProperty("_EmissiveColor") or HasProperty("_EmissiveColorMap")
Next set the color... You need to specifiy an HDR color
[ColorUsageAttribute(true,true)] in the editor
public color EmissiveColor (or get the color from the material)
Then set the color material.SetColor("_EmissiveColor", EmissiveColor * emissiveIntensity) also for _EmissiveColorMap
❗ Reminder that 0 times whatever is 0... so you need to set a color with an emissive first.

to get the HDR color value from a material: material.GetColor("_EmissiveColor") as well as _EmissiveColorMap

I went through this because I have a game where the enemies have body heat and when they're killed the bodies cool off, this is all done through emissive values.

The emissive keywords for the shaders are different for any other shader than Hdrp\Lit so you have to turn on debug to view what the emissive keywords are

[eternal laurel]

Yeah I did all that still didnt work

I just made a shadergraph with a emission node

Its just stupid that the lit shader does not work in the same way

[vocal copper]

is there any way to convert hdrp materials back into built-ins?

[digital spire]

nope. you need to create quad mesh yourself.

[wild cloak]

i tried it but there is a lot of artifacts and light leaks 😦

I'm using a mix of lightmap and apv, i enable lightmaps only on the objects with apv artifacts

mostly lightmaps for indoor

Guys ..
I'm using hdrp custom pass
The problem I'm having is when i have many passes
the last pass overwrites the one before it

[scarlet hull]

So, if the last pass "overwrites" the one before, does it mean it re-render objects over what the previous one already rendered ?

[wild cloak]

I'm not sure, There is no vertex pass only frag pass

just a full screen effect

this is the execution code
` protected override void Execute(CustomPassContext customPassContext)
{
if (material == null)
return;

    if (targetLayer.value > 0)
    {
        CoreUtils.SetRenderTarget(customPassContext.cmd, rtBuffer);
        CustomPassUtils.DrawRenderers(customPassContext, targetLayer);
    }

    customPassContext.propertyBlock.SetTexture(BUFFER_TEXTURE, rtBuffer);
    ShaderProperty(customPassContext.propertyBlock);
    CoreUtils.SetRenderTarget(customPassContext.cmd, customPassContext.cameraColorBuffer);

    DrawPasses(customPassContext, material);
}`

[scarlet hull]

So, if I read properly :

• you're rendering some objects in a buffer
• then you draw a fullscreen pass with this buffer

am I right ?

[wild cloak]

I am allocating the buffer but I'm not using it yet

So basically the buffer is not used

instead i get the color buffer in shader using CustomPassSampleCameraColor method

` float4 color = float4(0.0, 0.0, 0.0, 0.0);

    // Load the camera color buffer at the mip 0 if we're not at the before rendering injection point
    if (_CustomPassInjectionPoint != CUSTOMPASSINJECTIONPOINT_BEFORE_RENDERING)
        color = float4(CustomPassSampleCameraColor(posInput.positionNDC.xy, 0), 1);`

[scarlet hull]

Hum 🤔 . So this is just outputing the camera color again. But it overwrites what has been rendered by previous custom passes ?

[wild cloak]

yeah

I'm using this line CoreUtils.DrawFullScreen( customPassContext.cmd, material, customPassContext.propertyBlock, shaderPassId: material.FindPass("BloomPass") );

To draw the pass

[scarlet hull]

Tagging @woven sonnet if he's around, maybe he can help quicker than me 😅

[wild cloak]

I hope so

I've been stuck for two days for this issue

and another issue ..

I tried to use custom volume post processing

But looks like i can't do multiple passes in it

So i switched to custom pass

[scarlet hull]

The only reason I could think of is that the shader is sampling from the color buffer, and not the camera backbuffer.

[wild cloak]

it could be

But i didn't found any api or docs anything

[scarlet hull]

Which kind of makes sense when I think of it, my wild guess is that you'd need to copy yourself the camera backbuffer before your full screen effect

[woven sonnet]

Hey @wild cloak , which injection point are you using in your custom pass volume? and is MSAA enabled?

[wild cloak]

hi there, The injection point is before post process, MSAA is disabled

[woven sonnet]

Hum, I see. So at this stage, the color buffer sampled from the fullscreen shader will point direction to our color pyramid (color with mips), this allows to create effect that blurs the color buffer cheaply. The probleme is that this color buffer is not the current camera color one, so all the objects rendered in-between by custom passes are not in this one. I guess that could be your issue?

[wild cloak]

I really didn't understand anything, But does this custom pass re render all objects?

I'm using it only for post processing

[woven sonnet]

No, it doesn't re-render the objects. Just to be sure, the thing that gets overwritten is it also executed in a custom pass at injection point "Before Post Process" but before the one you posted?

[wild cloak]

Now i tried to use the RTBuffer, but its the same

[wild cloak]

yes

[woven sonnet]

Ok, so in your fullscreen shader, if you want to read the current color and write to it, you'll have to do a copy of the current color because you can't read and write to the same texture in a shader. It's an API limitation

[wild cloak]

and when i used it on the rain shader, the rain shader just gone like its not working

[wild cloak]

How can i do that?

[woven sonnet]

There is a copy function in CustomPassUtils, you can take the custom pass context cameraColorBuffer as source and allocate a new buffer in your custom pass to set as destination

[wild cloak]

so i changed the code to this

[woven sonnet]

Once the copy is done you can pass the copied texture in parameter of your shader and sample it instead of using CustomPassSampleCameraColor

[wild cloak]

allocating rtbuffer = rtBuffer = RTHandles.Alloc( Vector2.one, TextureXR.slices, dimension: TextureXR.dimension, useDynamicScale: true, name: "RTBuffer" );

i copy it like that customPassContext.propertyBlock.SetTexture(BUFFER_TEXTURE, customPassContext.cameraColorBuffer);

then i draw the pass

then i sample it

like this

float2 uv = posInput.positionNDC.xy; // Load the camera color buffer at the mip 0 if we're not at the before rendering injection point if (_CustomPassInjectionPoint != CUSTOMPASSINJECTIONPOINT_BEFORE_RENDERING) color = float4(CustomPassSampleCameraColor(uv, 0), 1);

[woven sonnet]

This is not a copy, it'll just pass the texture to the shader

[wild cloak]

So shouldn't it work?

it looks like this now

[woven sonnet]

And this code is sampling the "color pyramid" I was talking earlier, not the current camera color, so it'll not work

[wild cloak]

and when i disable the pass it looks just white

until i disable the whole volume

[wild cloak]

so the color pyramid is pure camera colors? without any effects?

[woven sonnet]

If you look at the pass diagram, inside post process there is one named "Color Pyramid Distortion", you get the color buffer from this step

https://docs.unity3d.com/Packages/com.unity.render-pipelines.high-definition@16.0/manual/images/HDRP-frame-graph-diagram.png

[wild cloak]

I see

So if i get the color buffer from this step, what will be the difference?

[woven sonnet]

CustomPassSampleCameraColor already returns the color from this step. The problem is that it doesn't include the render / post process made with custom passes in "Before Post Process"

[wild cloak]

ohh

[woven sonnet]

You need to get the camera color buffer from Before Post Process to get it working, and it's in customPassContext.cameraColorBuffer

[wild cloak]

I'm already doing that

So set texture won't work?

[woven sonnet]

But because you can't read and write to the same buffer (current camera color buffer) you need to make a copy first. Or if you can get away without reading the color buffer it'll be even easier

[wild cloak]

Isn't just like copy?

[woven sonnet]

No, copy will copy the whole content of the texture to another one, setTexture just tell the shader to use this texture

[wild cloak]

i see

[woven sonnet]

There is also the option to use a compute shader if you don't want to do the copy.

[wild cloak]

So when i draw the pass it won't be applied on the camera color buffer?

Sorry but I'm really new to this

[woven sonnet]

It will not get applied to the color pyramid (the one from CustomPassSampleCameraColor) but it will get applied to the current one (customPassContext.cameraColorBuffer)

[wild cloak]

Oh

Now i understand

[woven sonnet]

It's confusing because there are multiple color buffers in-flight at the same time. We do this to be able to read and write to the color buffer in a single pass (because they are different buffers)

[wild cloak]

it licks my brain

i've been into shaders for 4 days

So i allocated rtBuffer

and i copied the cameracolorbuffer

like this

CustomPassUtils.Copy(customPassContext, customPassContext.cameraColorBuffer, rtBuffer);

and i told it to use the rtBuffer

like this

customPassContext.propertyBlock.SetTexture(BUFFER_TEXTURE, rtBuffer);

should i set the rendertarget to the rtbuffer?

[woven sonnet]

No, you need to leave the render target to customPassContext.cameraColorBuffer otherwise the result of your draw will go into the rtbuffer, not the camera buffer.

[woven sonnet]

It's good like so, now you need to sample it in the shader like so:
SAMPLE_TEXTURE2D_X_LOD(_Your_RT_Buffer_Name, s_trilinear_clamp_sampler, uv * _RTHandleScale.xy, 0).rgb;

_RTHandleScale.xy is a global scale factor to avoid stretching problems when sampling your texture

[wild cloak]

I'm doing it like this
color = SAMPLE_TEXTURE2D_X_LOD(_BufferTex, s_linear_clamp_sampler, uv, 0);

uv is set to this

float2 uv = posInput.positionNDC.xy * _RTHandleScale.xy;

current code is :
` //Copy the cameracolorbuffer to rt buffer
CustomPassUtils.Copy(customPassContext, customPassContext.cameraColorBuffer, rtBuffer);

    //Direct the bufferTexture to RTBuffer
    customPassContext.propertyBlock.SetTexture(BUFFER_TEXTURE, rtBuffer);

    ShaderProperty(customPassContext.propertyBlock);

    //Set the results of our passes to this buffer
    CoreUtils.SetRenderTarget(customPassContext.cmd, customPassContext.cameraColorBuffer);

    DrawPasses(customPassContext, material);`

it renders just white

even if the pass is disabled, until i disable the whole custom pass volume

sorry my bad, i fixed it

thank you so much, it works now

[woven sonnet]

Nice 🙂

[wild cloak]

you are the best 😄

Now i will try to figure out how to do multiple custom pass in one shader on my own

[wild cloak]

I'm trying to do multiple passes

like this

` protected virtual void DrawPasses(CustomPassContext customPassContext, Material material)
{
CoreUtils.DrawFullScreen(
customPassContext.cmd,
material,
customPassContext.propertyBlock,
shaderPassId: material.FindPass("BloomPass")
);

    CustomPassUtils.Copy(customPassContext, customPassContext.cameraColorBuffer, rtBuffer);
    customPassContext.propertyBlock.SetTexture(BUFFER_TEXTURE, rtBuffer);

    CoreUtils.DrawFullScreen(
     customPassContext.cmd,
     material,
     customPassContext.propertyBlock,
     shaderPassId: material.FindPass("BlendPass")
    );

}`

But itsn't working

if i switch the names of passes it works

@woven sonnet any idea?

[woven sonnet]

To do multiple passes, you need to do something like this:

• Bind customPassContext.cameraColorBuffer (set texture) to the first fullscreen shader
• Set rtBuffer as RenderTarget
• DrawFullscreen
  At this stage, rtBuffer contains your effect on top of the color buffer
• Bind rtBuffer to the 2nd fullscreen shader pass
• Set customPassContext.cameraColorBuffer as render target
• DrawFullscreen

Now your 2nd pass red from rtBuffer and output to camera color so you have your 2 effects in the camera color

Also to help you debug, because you usually can't see what happens nor Debug.Log useful info. I recommend you to install RenderDoc: https://renderdoc.org/ It's one of the best graphics debugger and it'll allows you to analyze what happen in every passes you add. Don't forget to name your custom passes so you can find them easily in the RenderDoc search

[frail bramble]

hey guys, how would you go about getting reflections for a single window pane that has a double sided material

Ideally I'd like to capture the reflection on both side

so the inside captures the reflection of the building and the outside reflects the outside portion

I know it would be possible to do by just using 2 planes but was wondering if there's a way around this

planar reflections and rendering layer mask are unfortunately disabled for the game I'm trying to get this done for

using unity 2019.3.15 hdrp 7.4.0

[shrewd moon]

Two separate glass surfaces with carefully placed reflection probe bounds, or anchor overrides (if those were available on HDRP, I don't recall)

[frail bramble]

yeah that's what I'm trying to avoid, was wondering if it could be done with just 1 plane

I know it's more of a hassle, but I thought it would still be possible nonetheless

I will have to look into anchor overrides

[shrewd moon]

Double sided materials need to be rendered on both sides all the same so you don't effectively save any geometry that way

[frail bramble]

ah okay

really stupid question

would it be possible at all with a single sided material and 1 pane

guessing not?

[shrewd moon]

I think not

[wild cloak]

Hi, i will try that, what if i have 3 passes, do i need many buffers?

[vocal copper]

Is there a way to convert HDRP materials to built in RP?

[shrewd moon]

No officially supported automated way, I believe

[wild cloak]

Worked great!!!, Thank you so much

But what if i have like 3 passes or more, do i need many buffers?

[woven sonnet]

You can reuse the same rtBuffer between the passes, as long as you read 1 buffer and write 1 buffer in every pass you only need 1 temporary buffer.

[eternal laurel]

Not sure if I should ask here or #↕️┃editor-extensions . Can we extend the default material inspector for hdrp to have a drop down with the material type like Wood, Concrete, Metal etc etc and then somehow use that data to drive our sounds and vfx

right now we have a seperate component that needs to be configured, Of course having a naming convention for the materials is a posibility

that is without modifying the package itself to make the shaders use the custom extension

[scarlet hull]

You could make a copy of the shader UI code in your project for modification, and assign this a custom inspector for you shadergraph ?

Or is it for ght provided HDRP/Lit shaders ?

[eternal laurel]

Its for lit I would like to avoid having to use a shadergraph for everything

Or redo all of the lit functionality

[scarlet hull]

well, issue is that extending the material inspector would not be enough, you'd also need to store that information in the material itself :/

[eternal laurel]

Wouldn’t it be possible to query the inspector at edit time via OnValidate or something?

[scarlet hull]

Not really :/

I think your best option is to just add some script on the object to differenciate the footsteps sounds required.

[onyx lark]

perhaps you could do something with PhysicMaterial instead

which would be associated with the collider(s), rather than the renderer

[eternal laurel]

that was our previous system, we ditched it since it's even more work to maintain the physics materials and their names

[twilit swift]

How can I keep volumetrics when baking lighting in HDRP?

Ping when reply.

[dawn sorrel]

Hi! can anyone help me?

no error in the console

2d cookie atlas max

[twilit swift]

For some reason this light got baked and preserved the volumetrics but none of the other lights did.

[shrewd moon]

Volumetrics can't be baked
I expect that all of your lights need to be of type mixed

[twilit swift]

They are mixed.

But still no volumetrics.

[shrewd moon]

Are you sure it's only one light that works with it? And that what we're seeing is not just the distance cutoff of the fog volume

[twilit swift]

Yes I'm sure because it's the only showing in a whole warehouse map, though I found another 2 working on the other warehouse, but none of the other lights are working..

[shrewd moon]

Not sure what the problem could be
I'd double check that the working and not working lights have precisely the same properties, and maybe duplicate one of both and bake again to kind of prod at the problem

[twilit swift]

All of the lights have the same properties, the fun thing is that if I duplicate any of the non-working lights they have volumetrics.

[shrewd moon]

That confirms it's not an individual problem of the light or its properties at least

I would also place some dynamic meshes under them to see if the non-volumetric ones light anything in realtime at all

If they cast no light at all, it could be light limit related
If they cast light but just no volumetric light shaft, that would seem to confirm that it's purely a fog volume problem

[midnight trench]

I have just started a project using HDRP (2022 LTS) and put a area light in my scene marked as baked with the rectangle shape. but when I bake it, the shape is completely ignored using the range value instead. This seems to be intended but makes me wonder, what is the point of having a rectangle shape option if it is going to be ignored anyway? And if it's a case of, realtime only, then why is that not marked like with the other two shape options?

[brisk cape]

i've got some shadow issues but i don't want to interrupt other discussions so i will make a thread

[eternal laurel]

Im still stuck with this one. All the info I can find is old. People claim it’s related to decals or particle trails but we need both in the project

i did as you suggested for the two passes, while im using two passes there is something weird happening

[pastel oracle]

I have a scene in VR, Whenever I load the scene, everything looks kinda brown/yellowish, I'm thinking that's because I come from a previous scene where the physically based sky is kinda brown like it's morning. If I disconnect and spawn immediatly in the scene, All my colors look good. Is there a way to like clean/refresh the camera on demand? Or anyone that has experienced this? Can't seem to replicate in regular screen

[wild cloak]

Seems like a bug, do you have physically based sky enabled in both scenes?

[pastel oracle]

Nope only in one scene

[wild cloak]

yeah thats a bug

just enable it in the other scene

that should fix it

[pastel oracle]

I am now testing with both scenes the same sky and seeing if that fixes it

[wild cloak]

yea it will work

[pastel oracle]

Yeah but I have another issue, I change the directional light rotation in my game for like a day night cycle

But once I go from like midday to morning and back to midday, the second midday has an orange vibe to it

I also should say I don’t really smooth it over time, I just set hardcoded values

Any clue how I could get around this?

[wild cloak]

thats happening in the build

[pastel oracle]

Yep

[wild cloak]

or inside the editor

oh

[pastel oracle]

Only build

[wild cloak]

alright

[pastel oracle]

In Vr

[wild cloak]

can you try to disable all post processing volumes

in both scenes

and make a build

[pastel oracle]

Yeah good idea

Thanks for the help

[wild cloak]

you are welcome

[sterile knoll]

You would not need a custom component. Create a "Sound Database" scriptable object that maps from material to audio clip array. Then query the materials of the hit surface to determine the material, look up the material in the database, retrieve the sound array, play a random sound.

You can extend the material Editor, and with this approach effectively have a drop-down that lets you specify the "surface type" by querying the sound database.

[eternal laurel]

We already have the component, my questions was HOW to extend the material inspector to have that dropdown

[sterile knoll]

You can't with a component because materials don't have object context iirc.

You'd have to use a singleton scriptable object, like the approach I mentioned. It's very trivial to create, and more extendable than components.

[eternal laurel]

I think we are talking about two different things

I want a dropdown inside the material inspector of the lets say all built in hdrp shaders

I dont want my level designers and environment artists to have to hook up materials in a SO

[woven sonnet]

Not sure what could cause this, I don't see anything wrong with the scripts

[sterile knoll]

They won't. The material Editor would automatically assign the material to the scriptable object. The drop-down would be driven by the SO.

I'll see if I have time to make a mock-up

[eternal laurel]

That doesn’t sound like a workflow improvement

[sterile knoll]

@eternal laurel This?

public class Example : MonoBehaviour
{
    private void Update()
    {
        if (Input.GetKeyDown(KeyCode.Space))
        {
            if (MaterialDatabase.Query(
                new Ray(Vector3.up, Vector3.down),
                out var record,
                out var hit,
                1000f,
                LayerMask.GetMask("Default")))
            {
                var clip = record.audioClips[Random.Range(0, record.audioClips.Length)];
                AudioSource.PlayClipAtPoint(clip, hit.point);
            }
            else
            {
                Debug.Log("No material at the hit surface.");
            }
        }
    }
}

• Place your MaterialDatabase in the resources folder, and make sure there's only 1.
• Define your "Records" which are used to lookup the "resources" (audioclips, etc.)
• Your designers can select the material type from the dropdown, and never have to worry about anything else. They don't have to edit the Scriptable Object.

This is just an example though, your team would need to make it work as you want.

[crimson holly]

any idea why my lit dust particles reflect light

[shrewd moon]

Post only in one relevant channel at a time please

[eternal laurel]

This is great thank you. I was specifically asking how to inject the dropdown. Hope it works with the hdrp gui as well.

[dawn sorrel]

Does anyone know how I'd go about getting a normal HDRP/Lit material and convert it to a transparent surface type?

Basically I want to create a preview image which will use the objects material but make it transparent with a green hue

I want to maintain normal maps and the base texture

[opal mica]

Hello! My volumetric clouds are brown. I've tried every setting I can find and Google has never heard of it. Does anybody know why this happens? Thanks!

[fluid merlin]

If you have an HDRI image set for the sky, this can happen when combined with the directional light settings. Try removing the HDRI sky and see if it fixes it or switch the sky to Physically Based Sky

[opal mica]

I am using Physically Based Sky, so I don't think that's it unfortunately. I noticed that changing the ground tint of the Physically Based Sky override changes the hue of the clouds, but setting it to white makes the ground look weird. Any way to decouple the color of the clouds from the physically based sky settings or something?

While I'm not using an HDRI Sky at the moment, I have used an HDRI in the past. Could that be baked onto some map that the clouds use somehow, despite the fact that I've cleared the baked lighting data?

[crimson holly]

sorry

[dawn sorrel]

is their a way to do real time path tracing, instead of just ray tracing, there are a few tech demos and ue5 is aperently going to add real time path tracing soon, and cyberpunk also has it, but unity seems to lack it and I've found no discussion sorounding it,

also can you use ray tracing and get more then I think 8 reflection bounces? something closer to 78 like in unreal engine? or is that a no

also also, is the ray tracing shaders editable? sense it's a SRP?

[wild cloak]

hmmmm

[loud leaf]

Nope, if you want to do proper real time path tracing, HDRP needs a lot of modifications. You can do this yourself (I am also doing this for my game) but one way or another you will run into trouble, unnecessary overhead, etc, because HDRP is aimed at a different use case.

Why do you need more than 8 reflection bounces? Can you even notice more than 3 in your scene?

Ray tracing shaders are editable. Sideload your packages and look for .raytrace files.

The reason UE5 and Cyberpunk 2077 have made progress in this area is because these branches/implementations are maintained by the same people active in this area of research.

[dawn sorrel]

Why do you need more than 8 reflection bounces? Can you even notice more than 3 in your scene?
well when you put a mirror next to a mirror yes very much so xD, but also I wanna make a kinda like weird abstract kind of "showcase' thing mostly just for myself

generally in most my games games, I use 2 bounces

but yeayh, thanks :D

[loud leaf]

I think Unity will play the probe/baking game a little longer until we are -really- there when it comes to hardware. Currently the hardware is advertised as ready for it but reality is that everything in real time path tracing depends mostly on pushing the latest algorithms to their limits, hacks, cutting corners and weird tricks. Open up something like Portal RTX and check out the rendering debug menu to get a good idea of everything that's currently going on to get to that final composition.

It's a lot of fun though, and not very hard to get a basic real time path tracer up and running, but to get rid of all ghosting, smearing and noise while keeping the result detailed, unbiased and the framerate high is another story. 😄

Even Cyberpunk 2077 Overdrive can look like complete shit if you pay attention to the details.

[dawn sorrel]

32 bounces crashes 0-0

but 16 bounces runs at 40 fps without dlss in 1080p so I have no idea why it's capped at 8 bounces by default

also thanks :D

[smoky tide]

so is hdrp just incapable of Scene Depth

the node does not seem to work in shadergraph

and neither does HD Scene Depth

[scarlet hull]

It should just work.
BUT scene depth is only available (or "ready") after the opaque objects pass, so for transparent materials

Or forward opaques

[dawn sorrel]

Ok anybody have any tips or good support threads about baking lighting while using APV in 2022 LTS hdrp?

Getting crash shortly after starting bake.

[opal mica]

Hello! I'm trying to blend between two global volumes that each only contain the Physically Based Sky override. The problem is that blending between them triggers a process called UpdateEnvironment which is extremely performance intensive and grinds down the fps to like 15. Should I not be blending volumes like this, or is there a way to change between night and day skies with less performance cost? Thanks in advance!

[scarlet hull]

Do you maybe blend some of the settings listed here, that trigger heavy recalculations ? : https://docs.unity3d.com/Packages/com.unity.render-pipelines.high-definition@16.0/manual/Override-Physically-Based-Sky.html#warmup-performance-impact

[opal mica]

Yeah, I change the ground tint. Is there a different way I should be doing that?

[scarlet hull]

I'd say to not change it 😅

[opal mica]

Haha okay, but if I keep the day's ground tint during the night it looks really off. I feel like there must be a way this is supposed to be handled?

Maybe the ground tint is supposed to always be black for dynamic scenes?

[loud perch]

Did someone encounter frozen beach waves in water system? They are working just fine when in Scene View, but in Game View they are not moving.

[scarlet hull]

Even in play mode ?

[scarlet hull]

I've juste tested for confirmations, and the final ground tint of the sky is affected byt the light intensity and direction, so it really acts like an albedo/diffuse color (which makes sense).
So, just set the tint to match the color of the ground of you scene, and it should stay the same during night and day (as in real life, the ground albedo doesn't change 🙂 )

[opal mica]

All right, I must have misunderstood its purpose somewhat. Thanks for the help, appreciate it! ^^

[pure canopy]

Anyone encounter this issue with terrain details in HDRP? This perpetual blurry grass happens when any motion blur is enabled. I've tinkered with all the terrain detail settings with no avail. They render fine in a demo scene, so I'm really puzzled.

[loud perch]

Yes, even in play mode, but when i create build, there is also fine.

Is there any buoyancy system for water system?

[scarlet hull]

Yes ! (gimme some time to grab the doc page)

https://docs.unity3d.com/Packages/com.unity.render-pipelines.high-definition@14.0/manual/WaterSystem-scripting.html

Not script/component provided to instantly do buyancy though, you will have to script a bit, but it is pretty straighforward imho

[dawn sorrel]

Naughty Buoyancy is free on github

@loud perch

[scarlet hull]

Doesn't seem related to HDRP water system

[dawn sorrel]

Oh yeah I forgot it's not oops

I'm using Dynamic water physics 2 asset for my buoyancy. It works there is a user script for it with the new hdrp water, but he's also doing an official integration soon.

[scarlet hull]

@loud perch You can also look into the HDRP water samples (in the package manager) where there is a very basic buoyancy script

[merry heart]

Not really sure where to put this but i guess this makes enough sense. I've been working on this scene but recently encountered some camera issues. For some reason, these spots on the mountain are not rendering in game. My camera clipping is set very high (5000 atm for the far plane) so I don't think that has anything to do with it. Anyone else got some ideas on this?

[fluid merlin]

Clipping aside, it almost looks like the camera is under the mountain or something, try enabling double sided material to troubleshoot. Also, maybe baked occlusion culling? Incorrect LOD group settings is another guess....

[merry heart]

the terrain has no LOD stuff but there are some boulders about that do have LOD group components

[fluid merlin]

I would try to troubleshoot it by creating another camera as a test first, if that's not it, another terrain as a test, then if that doesn't work, start disabling other gameobjects in your scene to narrow it down.

[merry heart]

seems better on a new terrain, though ocassionally getting some empty spots. i tried disabling a bunch of objects on the original which didn't have an effect so could be something to do with the camera that isn't distance related

still not sure though as it has been like this on previous cameras i've used as well

I added a new one to the scene very recently to make a new player controller

and no different when it comes to the flickering spots

I kinda wonder if the occlussion just needs baking again

[fluid merlin]

Yeah, baked occlusion is a nightmare... I don't think Unity has updated it in the past 8 years. They need a realtime Z based system, it runs ultra poorly with respect to resources, on large levels, forget it. Clear your baked data and see if that's it. Flicker is a good indicator of it.

[merry heart]

yep! that was it

just baked it again and it looks fine

[pure canopy]

just gonna bump this as I am still stuck. I imagine it has something to do with motion vectors on the grass but I have no clue how that's being applied differently in this scene

[topaz ravine]

@pure canopy don't you have disabled depth prepass? can be that too

[minor depot]

Allegedly burst occlusion culling is on the way at least

[fluid merlin]

That should be interesting, I didn't know they had anything on the roadmap for it. 👍

[open tree]

I have this small object in front of the window and I dont like 1. how AO is creating this glow around the object and 2. how it is being distorted by the glass (glass is custom shader which is using HD scene color and distorting it). How do I fix this? is there any way to use custom pass or something ?

[scarlet hull]

For AO, there is not much to do except by tweaking the SSAO settings.

For the glass, you would basically need a depth rejection (so, also sample scene depth and don't deform pixel that are closer to the camera).
But did you try with the standard shader, in transparent mode with refraction ? Or use refractions in shadergraph instead of manually sampling scene color ? Built-in refraction should automatically solve this issue

You could draw the object mesh in a custom pass, after refraction for example, if will be then skipped by AO and not refracted (and not in the scene color buffe), but it seems a bit overkill for a single object

[open tree]

I am using shader graph to create a custom shader for glass because it has animated rain effects. So I am using HDscene color. Is there any other way to achieve this?

[scarlet hull]

Yep, use the shadergraph to drive the normal of a transparent shader with refraction

Well, I mean both work, but with the refraction method you don't have to fight with the pixels depth youself

[open tree]

okk I will try that. I also tried using render to texture using different camera but the bloom then not working at night.

this one is using render to texture. which solved the issue for foreground stuff but bloom is broken.

this is what it should be

[scarlet hull]

Not 100% sure, but could be because your RT was not HDR, and lost the high intensity color values

[open tree]

i set it to R32B32G32 float but no change.. not sure why

[scarlet hull]

I think that you should disable post processing, exposure and tonemapping on the capturing camera. Really keeping raw color values

Not, still, not the best solution, since you're renderinb two cameras :/

[open tree]

yeah

[open tree]

how do I do this? I tried using the refraction method and it did solve most of the issues. But the distortion method is looking more realistic. I played with normal strength, refractive index and thickness but not achieving the similar result. For now I am okay with it, but since the custom pass may solve the AO issue as well, I kinda wanna know how to do that.

[scarlet hull]

Use a dedicated layer mask for your object, don't render it with the main camera, but render it with a draw object custom pass

[open tree]

It worked!! Thank you so much! @scarlet hull

[tawny silo]

I've updated a project to 2022.3, this project has an asset from the store in that used UnityEngine.PostProcessing this is now no longer present .. what has it been changed to? / Moved to in 2022.3 ?

Is that just for PP v2? If so, wonder why it didn't have errors before updating 🤔

[shrewd moon]

I think it is that, or UnityEngine.Rendering.PostProcessing for PPv2 stuff
HDRP would use UnityEngine.Rendering and UnityEngine.Rendering.HighDefinition for it

[tawny silo]

It's probably not gonna be a quick conversion

[fluid merlin]

Nice lighting on your scene, what was your workflow for this?

[open tree]

@fluid merlin I tried using baked lighting at first but I wanted to have day-night cycle. So I used pre-computed GI with some area lights and reflection probes that only updates at certain time of the day. Specially when lighting change is significant like dawn or dusk. It is not perfect solution, because when they update there's a noticeable performance spike but it is art project environment anyway.

[digital spire]

How would I create a fullscreen effect that will apply grey scale filter like post process effect but omit objects on specfic layer? HDRP 2022
The full screen shader is easy to get working but IDK how to ignore specific layer

[digital spire]

ah nvm there is a sample of that in the github

[shrewd moon]

What render pipeline is it then? This is the HDRP channel

[boreal badger]

But I made another build and change shadow settings on Al level quality and works well but I want to know what made this bug

Shadows ?

[shrewd moon]

Android build issues on built-in render pipeline are not really in the scope of this channel
When you make a post in a more correct channel you'll want to describe the problem in greater detail than "this problem"

[waxen lantern]

if you enable raytracing, these rendering methods (reflection / refraction, ambient occlusion) can operate in world space and avoid a lot of the limitations and artifacts of screen space rendering that you wish to avoid. typically at the cost of performance and compatibility (if that matters in your case.)

you won't need hdscenecolor, rendertextures, or a custom pass to complicate the rainy window at all --just a shader or texture to affect the windows material's normal map. set the material properties and the raytracing will take care of the rest.

ah, it seems you achieved acceptable results without raytracing, by using a custom pass per remy's guidance 👍

[open tree]

@waxen lantern yeah, I tried RT. But the GI was noisy, and to get a decent quality the performance hit was way too much. And I want to run it at 4k, so I definitely need DLSS for that, but as the camera isnt moving at all, DLSS is having trouble at low light condition and I am getting a ton of ghosting on small particles and the curtain. But I always try RT or pathtracing first because that's what I am used to, I am an 3d artist, not exactly a game dev. Infact even in this case I used Pathtracing to get an idea of how the real lighting should work and then matched it with normal lighting solutions.

[waxen lantern]

ah, i see. very well explored. i assume this is for a livestream application? it would be cool to see it in action when it's ready.

[open tree]

@waxen lantern yeah, I am actually exploring unity and learning environment design, but yeah I made it for my friend's stream. Will definitely post more about it when it is finished. 🙂

[waxen lantern]

@open tree cool! also, this may be intentional or known but in the daytime scenes the white coffee mug seems to be unnaturally lit / bright compared to the other objects in the scene apparently receiving the same amount of light?

[open tree]

@waxen lantern yeah it was light probe issue, fixed it now

[errant timber]

Does anyone know why when I put an HDRP unlit color shader on an object, other objects can be seen through it? Maybe it does not write to the depth buffer?

[smoky tide]

how to make this uranim glow

[hard atlas]

unrelated but what the hell is this scenario

are you uranium mining from trees in the woods

lmao

[fluid merlin]

In general, you have to set the emissive property of a material, optionally an emissive texture mask with that. Also, set the Bloom on the global volume. If you want to create a glowing outline, there's a few tutorials on how to do that on youtube by searching for unity outline shader, etc.

[smoky tide]

thankyou

[smoky tide]

i am still testing stuff. Thats why there is a floating table there too

[livid rapids]

Hi! Does anyone know how to control the Local Volumetric Fog values through script?

Cant seem to find the correct method

Tried using LocalVolmetricFog and LocalVolumetricFogArtistParameters but neither of them let me control the Distance of the fog

[livid rapids]

nvm its just a random name called MeanFreePath

[twilit swift]

Does someone know if there's something like nanite for Unity?

Ping when reply.

[shrewd moon]

No

[twilit swift]

There's nothing equal to that in Unity?

Dang.

[loud leaf]

There's this, but it's still in development.

[faint sluice]

Hey guys. I Have problem with the light performance. My scene is small, just one room with bathroom, the triangles amount are around 40 maybe 50k. But with the lighting its showing me amount around 1-1.5 milions triangles and a lot of draw calls. I tried diffrent settings, but still around 800k triangles. How can i reduce this and make performance better? i tried occlusion culling, bake everything, shadowmask mode and things like this. I have no idea at this moment 😦

[terse basalt]

try disabling shadows

[faint sluice]

disabling shadows works, but i need these shadows.

:/

eveyrthing is setuup on baked and lighting mode is shadowmask

[terse basalt]

reduce the shadows distance if you don't need that much

[faint sluice]

@terse basalt over here? or some other setting?

[terse basalt]

what is that lol

[faint sluice]

so where can i find it?

[terse basalt]

like I have it in the postProcessing profile

[faint sluice]

okej

[terse basalt]

here

[faint sluice]

thanks, but unfortunetly nothing changed. 😦

[terse basalt]

:/

[terse basalt]

well you could manually disable the shadows for the objects that don't really need to have shadows

[faint sluice]

ok, i will try that also, its really struggling me. Since i did a a lot of tests :/

[terse basalt]

or just set them to static, set the light to baked, and bake it

[fluid merlin]

Realtime lights with shadows kill performance. Turn shadows off on lights where it's not 100% necessary. Set the range on shadows for all lights. Turn off volumetrics on lights that don't need it and set a low range value. You can also turn off shadows on meshes too, on the mesh renderer turn Cast Shadows to off.

My own tips and a link to the "mega thread" performance tips for HDRP:

[hard hearth]

Heya! anyone know how to keep color on a Decal Projector in HDRP? (yes, i am using Affects Transparent on the projector otherwise it doesnt show up on the water)

at the moment, my decals all turn white 😦 while the texture i imported is orange

Ok yeah well... limitation for the transparent thing?

also this happens with decal on water

[fluid merlin]

I've had some luck on the transparency issue by unchecking options on the Surface Options for the material for the decal. I usually only check off "BaseColor" and uncheck everything else.

[hard hearth]

oh really! 😄

[hard hearth]

For the last image it worked, but the color doesnt appear, sadly

[fluid merlin]

I haven't tried it on the water shader, but my process is usually, transparent background, white lettering/design in the texture. Color adjusted from the shader.

[hard hearth]

mhm

[harsh basalt]

The mesh shader is on the road map now, but for this kind of feature that can't work on multi platform Unity will not make it a high priority.

However, mesh shader is part of the DX12 ultimate. Since dx12 for unity is out of preview, mesh shader and other DX12 only features may be soon(means 1 to 2 years).

[twilit swift]

I ain't gonna pay like $100-$500 just for that.

[shrewd moon]

It's unlikely to be ready for a long time so your worry is premature

[fossil nacelle]

Hello, I've been using hdrp for a while now and for the past few days I've been getting these same error messages over and over in 2023.1.4f1 and its causing many graphical errors glitches which I have no idea what the cause is. I believe it may be a unity bug but it might be my error causing it.
The three errors are (with stacktrace):

[scarlet hull]

This is pretty obscure issue that should not happen :/
Would you be able to send us a reproduction project (through a bug report) ?
You might be able to disable async compute in the frame settings to work around the issue.

[sly igloo]

anyone got a example + documentation of the volumetric cloud maps?

by that I mean these

[fossil nacelle]

I'll submit a bug report, it's fixed by disabling async compute for building light lists in frame settings. I think this started occuring when I updated a certain package; I don't remember which.

[scarlet hull]

That would be very helpfull for us, thank you !

[fossil nacelle]

also quick question: when I send the bug report with the example project, will the unity team see some project details (e.g. name, contents of game, etc...), if so they are getting omega trolled

[scarlet hull]

Using the bug reporter tool, all you project data will be sent, including assets, project settings and even the Library folder (which sadly greatly increases the total size :/)

[vapid bronze]

does hdrp water supports custom colliders for underwater or only box colliders?

[twilit swift]

Hi, I'm getting this on the lighting settings, mixed lighting was working fine just a few days ago.

[twilit swift]

Hi, could someone help me? For some reason my editor is taking up to 7h just to process easy task such as clicking on the editor or doing any other simple task. And no it's not my specs, it's the first time this happens in like 3 years with this computer, but if you wonder it's a 5 5600x, RTX 3060 12GB, 32GB RAM 2133MHZ.

[loud leaf]

Which Unity version are you using?

[lunar girder]

why does the shadows look so weird

[shrewd moon]

Looks like normal maps are incorrectly defined or created

[lunar girder]

how can i set that the HDR effect is not so hard

[scarlet hull]

Tweak the exposure and tonemapper

[lunar girder]

where

[fluid merlin]

On the global volume. To make things a lot easier, create a new outdoor scene from the template. Copy sky & fog and directional light as a starting place.

[buoyant drum]

SOMEONE HELP PLEASE

[shrewd moon]

Someone will only be able to help if you describe how the problem appeared and what you tried to do at the time

And what the problem precisely is

[buoyant drum]

i deleted a package that had some shaders that help to get rid of a repeating tiled look on large surfaces for textures

but i had some reasons to believe that it was causing crashes everytime i try and bake

it would finish baking

importing assets would go to near 90%

and then unity would crash and thats another 3 hours of my time wasted waiting

so i got rid of this package

had some errors in the hdrp settings

there was a button that said "fix"

I clicked it and it did the complete opposite and fucked it all up

now these errors are constantly being spammed

[shrewd moon]

Not sure what it was meant to fix, and what was deleted along with the package so this is pretty tricky

You should always have version control for projects you don't want to lose so you can always revert any change

[buoyant drum]

hows that done

[shrewd moon]

Use a program like Git with a service like GitHub that tracks all project changes, but that's a whole topic

[buoyant drum]

alright ill look into

might have some sort of backup somewhere

if im lucky

[shrewd moon]

You could try to reinstall and reconfigure HDRP from scratch, or if worst comes to worst you can move the gameplay related assets to a fresh HDRP project as unitypackages

The graphical part that seems to be broken is usually entirely separate from them, so the problems should have no way to propagate through the game assets

[buoyant drum]

yeah

[shrewd moon]

But it depends how big of a role the package you originally deleted had

If your materials or post processing or rendering itself were using custom shaders from it, that would make it more difficult to remove

But that seems unlikely if they were just texture tiling related

[buoyant drum]

It was that and allowed extra bump details and things like that

That's basically what it was

But I wasn't sure about anything else with it

[shrewd moon]

Did you do test bakes with and without those shaders in a test scene consisting of only basic default meshes?

[buoyant drum]

But I got rid of it because that's the only thing I could've thought of that could be making my light baking crash at the end

[buoyant drum]

No because I was getting some hdrp modified asset errors aswell

And that package was the only possible thing

That could be doing it

So I got rid of it. Which fixed one problem and gave me even more lmao

[twilit swift]

Please help, my unity keeps stuck.

[rustic gull]

does anyone uses Surface Gradient Bump Mapping on unity 2023?

https://docs.unity3d.com/Packages/com.unity.surface-gradient-bump-mapping@0.2/manual/index.html

this

[rustic gull]

How do i fix it?

[rustic gull]

Will unity ever update it? or better just remove it from project?

Does anyone knows?

[lusty oyster]

So I'm working on settings right now and everything seems to work, but the MSAA setting just doesn't work. How do I fix that?

I can't really find any documentation to access this via script

[fluid merlin]

MSAA is only supported for forward only rendering in HDRP

[lusty oyster]

uh, ok then, i thought using both wont affect it

thanks

[fluid merlin]

I think you can setup a camera override to do Forward Only and then setup that camera for MSAA.... A lot has changed with that from HDRP version to version. Earlier versions of TAA were terrible, the TAA in 2021 is pretty decent.

I think the documentation for MSAA says you can set it to "Both" but I seem to remember some confusion in it because then it starts talking about cameras and such.

Ah, here ya go:
https://docs.unity3d.com/Packages/com.unity.render-pipelines.high-definition@14.0/manual/Anti-Aliasing.html

(I'd stick with TAA, but maybe your use cases calls for MSAA)

[lusty oyster]

thanks

[twilit swift]

Hi, how can I fix motion blur on HDRP VR?

For some reason it always looks blurry when I move the head or the hands.

[twilit swift]

Ping when reply.

[orchid breach]

How do i open a project with the template auto showroom hdrp?

[long scarab]

you should switch motion blur off (as a post processing effect) , on your HDRP asset there should also be a checkbox down in the bottom to deactivate motion blur in VR

[twilit swift]

I deactivated it and the HMD motion blur dissapeared but the object motion blur keeps showing.

[long scarab]

this can be missing motion vectors, especially if you are using TAA, TAAU, or DLSS

On SMR, you should also activate skinned motion vectors

[twilit swift]

How can I do that?

[long scarab]

just tick the checkbox 😉

[twilit swift]

You mean this?

[long scarab]

I have explicit checkbox under additional properties called skinned motion vectors, Unity 2021.3.28

[twilit swift]

I'm 2020.3.28f.

[long scarab]

I m 2020 3 28f

[frigid jungle]

why are none of my volume settings not affecting the scene even though my camera is in the volume collider?

[shrewd moon]

If you are using HDRP, uninstall the Post Processing package and configure a post processing volume that's correct for HDRP using instructions pinned in #💥┃post-processing

[frigid jungle]

ok ill try

[frigid jungle]

i used the volume component instead but still doesnt work

and uninstalled post processing package

[shrewd moon]

When you make a new Basic Outdoors or Indoors scene it will be created with post processing ready to go

[frigid jungle]

i just changed from urp to hdrp

so that may be why theres issues

[sweet night]

How can I fix these very dark shadows?

[open tree]

@scarlet hull @waxen lantern Thanks for the help with this one. It is complete now! A live starting soon screen for a stream. The assets are hard to explain, but they are handmade gifts by the fans. I modeled and textured them as close as possible.

[smoky tide]

how do i fix jagged lines in hdrp

[waxen lantern]

increase shadow quality and/or shadow resolution

[smoky tide]

out of nowhere there is now a strange line across the table

[sweet night]

Try tweak bias of shadows.

[smoky tide]

any reason this happens?

[knotty lily]

Looks like shadow cascades change point

[buoyant drum]

wanted to replicate this sort of similar look in unity. But I wanted to ask if anyone knows a better way for puddles, at the moment im just using a noise texture in the detail map part with smoothness. I was looking at those "decals" and was wondering if they would be any good? But I have not idea how to use them lol

[eternal laurel]

The hdrp sample scene has pretty decent puddle decals you can checkout and use

For really good result we usually use the layered lit shader with a dedicated puddle layer and height based blending and then we paint them on via vertex colors or use a mask

Depending on the geometry

[buoyant drum]

Oh nice

[smoky tide]

how do you stop shadows from being pitch black

i have no directional light and no skybox btw

[scarlet hull]

Have a source of ambiant/bounced lighting to provide light to shadowed areas.

So, "skybox" and / or baked GI

[buoyant drum]

do you know where to find this?

[pastel oracle]

Profiling the editor in HDRP goes ham

[scarlet hull]

When creating a new project, select "HDRP Sample Scene"

[buoyant drum]

Oh that one

[fluid merlin]

HDRP decals are the way to go, also pop up a baked reflection probe on top and adjust the Multiplier on the probe under render settings. You can also fade the decal for blurred reflections too without having to play with the reflection probe. You can also get a better reflection at times by unchecking AffectBaseColor on the decal.

https://i.imgur.com/Gs1uWrF.jpg

[smoky tide]

what is a GI

[shrewd moon]

Global Illumination

[smoky tide]

so i bake it and it stops the shadows from being pitch black?

[shrewd moon]

Baked lightmapping also simulates bounce lighting so yes

[smoky tide]

thankyou bro

[smoky tide]

can i have realtime global illumination

[shrewd moon]

Not very practically
Enlighten realtime GI and SSGI/RTGI are your only options

[smoky tide]

big problem is that this SSGI thing is not doing much

only 1 shadow was barely affected

[shrewd moon]

Then you may have to use ray tracing or enlighten

Enlighten requires static geometry because it's precomputed, though

[smoky tide]

im gonna have to have pitch black shadows then ):

[shrewd moon]

Why don't you use a bit of ambient / sky lighting as Remy suggested

[buoyant drum]

Nice, thanks for your help! Haven't ever used decals before so would you use some sort of noise texture or something or is there a painting system on these?

[sweet night]

My object become darker when my camera comes closer.

Can you say what's problem can be?

It seems like shadows has a range and it looks like it accumulates.

[heady pewter]

Your mixed lighting mode, or realtime shadow settings/shadow cascade settings

[sweet night]

Thanks, need to look.

[fluid merlin]

The easy way is to just grab the decals themselves from the unity hdrp demo template starter scene. Otherwise you can create your own, add the textures to a material, set the material shader to HDRP\Decal. If you want to create your textures from scratch, there's some blender/photoshop tutorials for creating water puddles. You just have to export the textures into Unity. If you search on Youtube for HDRP Decal, you'll see some tutorials on how to use the HDRP Decal projector

[buoyant drum]

well thats certainly alot better than what it was before! Thanks for your help and also thank you @scarlet hull

i just gotta mess with the reflection probes alot more lol

[fluid merlin]

There are shaders that do it too, but require more setup and config. The Ciconia Puddle and Rain shader is nice and only $10… it more for if you need depth for your puddle on a custom mesh, like tile, etc.

[buoyant drum]

Tried it but was only compatible with 2 versions of unity

And unitys support team is completely nonexistent

Asked for a refund and haven't got a single email back

[dawn sorrel]

Can anyone help me figure out why my shadows are wrong?

think it's something to do with the shadow cascade thingy?

[shrewd moon]

I would just copy all the settings from the HDRP sample scene when working with HDRP

[dawn sorrel]

So I suppose that means I need to create a new project with the HDRP preset

[shrewd moon]

Yes
I would export the level and game assets and import them into that new project
At least a few of them for starters to see how the new settings fare
Would also prefer to use the outdoors/indoors scene templates for their lighting and Volumes

[dawn sorrel]

Okay I'll give it a try, thank you

[shrewd moon]

With HDRP you need to have all the graphics settings right, the scene lighting settings right as well as camera and volume component settings right or it's going to look like ass, so it's better to not try to set them manually

The above screenshots look worse than URP or BiRP out of the box would

[dawn sorrel]

I fixed the shadows but yeh, it's been a struggle indeed

[harsh basalt]

I made a custom Stylized Sky in HDRP, video link: https://www.youtube.com/watch?v=zTzfgV4Ug1k
Github source code link: https://github.com/misakieku/StylizedSky

[smoky tide]

ive set all my shadows to 8k and this is what i get?

[fluid merlin]

A common cause of that in HDRP is too many lights per tile (16x16 pixels). Point lights with shadows and high ranges will cause an issue that looks like what you have there. It could be other things, but that's often common. Also, point lights with shadows are really, really bad in performance, you might want to try spot lights with short ranges if you have a lot of point lights with shadows.

[smoky tide]

is it causing this too?

[shrewd moon]

It seems there could be multiple issues with your shadow settings
I'd reference the ones used by the project and the lights in the HDRP sample scene

[fluid merlin]

Spazi is right, your shadow artifacts could be caused by a bunch of different things. Unfortunately, when it comes to lighting and shadows, unity (for better or worse) gives people a ton of options and the default ones are often not what people expect when they hit the "Generate Lighting" button. If you're new to lightmaping, this is a really good tutorial (although it's for URP, the basics are pretty much there). For whatever reason, the Unity tutorials are often not very good because they jump right into "your problem is UV mapping" and 99% of the time, it's just developer setup. Anyway, there's a bunch on youtube, but I liked this one for it's general approach in what people are actually doing: https://www.youtube.com/watch?v=okYhs6kQ0xw

[shrewd moon]

HDRP really expects you to know your way around industry standard lighting concepts and settings

[shrewd moon]

That's a good tutorial but I recall earlier they said they only want realtime lighting

[smoky tide]

That is right i want this to be realtime because im scared of baked things

Some of the interior objects move including tables and stuff

So im just worried it will mess it up

[shrewd moon]

HDRP's realtime lighting is just as complicated

Both of them you must study and practice to use correctly

[smoky tide]

I made it do realtime global illumination and it aint changed nothin

[sage shard]

hi anyone know a good free first person controller asset for hdrp?

[shrewd moon]

Character controllers have no relation or connection to render pipelines

[pastel oracle]

Can someone explain why my build version looks like this:

and my editor looks like this:

[loud leaf]

Are you using ray tracing?

[pastel oracle]

Nope

Testing different skies now, PBR, hdri,.. and see if that does something

annoying thing is that I have to build each time...

[loud leaf]

yeah

I've been having issues with environment contribution since january. Bug was confirmed in february but no fix yet, afaik. :/

[pastel oracle]

Yep same, also a lot of issues with VR and environments that I've been experiencing

[loud leaf]

Exactly that, yeah

[pastel oracle]

Do you have any tickets/bug reports that I can follow?

[loud leaf]

I'm just going to download the latest editor now and see if anything has changed 😄 maybe they forgot to update the bug report.

[pastel oracle]

Yeah I'm on 2022.3.4 so I can only update to 5 😄

[loud leaf]

I have a ticket but somehow mine are never public / links don't work.

https://issuetracker.unity3d.com/product/unity/issues/guid/OXRB-124

[pastel oracle]

Yeah It's not accessable for me

https://forum.unity.com/threads/vr-and-physically-based-sky-doesnt-work-well-together.1458916/#post-9152555

I have this forum thread

But not much response

I also tested 2023 Beta but no improvements regarding that as well

[loud leaf]

I think I even found the commit that broke this at some point, but it's not going to be easy to find that back now

I think it was when they did a bunch of changes to the sky atlas / sampling code.

https://github.com/Unity-Technologies/Graphics/commit/9440ed5a166877f1bebe9751e0b89eb1cbbc8846

That must be it 😄

Ok, 6 months later, did the same test in 2023.2.0b1 and it's still broken (and there is a new issue now)

I don't know what to say really.

[pastel oracle]

Nice haha yeah I don't think I know enough about graphics programming to find what I need

just a shame it's so unstable

[loud leaf]

I wish they would all just sit down, stop what they are doing and get things to acceptable state. Like that #FIXPUBG campaign back in 2017 (even had it's own website, that's how bad it was) after the community kept bombarding them with "fix the damn game" for months. :/

Yes, indeed.

[pastel oracle]

It has so much potential

[loud leaf]

It's not a talent/skill issue, HDRP team has the skills, I have no idea what's going wrong.

[pastel oracle]

Exactly. Like just focus a month or so on testing the already provided features and get those in a stable manner before adding new things

like the water system they just added

Yeah it looks nice and is very cool but I'm pretty sure it'll just add more complexity to it as it is already

Oh well, I'll just try and make 50 builds to find what's the issue and report on that

[loud leaf]

But yeah, these complaints aren't new, I don't think we will change anything here. 😄

[pastel oracle]

Nope haha

[pastel oracle]

Just found 'the issue'. When I disable realtime global illumination I get the same issue in the editor. Any clue how to get this to work in build? This is my first project in HDRP so I'm not sure if I'm missing something

[loud leaf]

No idea.

[pastel oracle]

Okay then I'll investigate further 😄

[loud leaf]

What version of Unity is this by the way?

[pastel oracle]

2022.3.4

[vague steppe]

is it somehow possible to compress the camera quality in real time? in the first image, it looks much more realistic becasue of the compression, but not in the second image.

[scarlet hull]

Real time global illumination here is provded by Enlighten, that is deprecated : https://docs.unity3d.com/Manual/render-pipelines-feature-comparison.html#lighting

[pastel oracle]

Oh okay, so I should use screen space GI?

[scarlet hull]

Do you need realtime GI ? Can't it be baked ?

[shrewd moon]

Render Target textures can be compressed and downsampled at runtime, I believe

[pastel oracle]

Preferably realtime, Wanna change lights by turning on and off and switching from day to night

[scarlet hull]

I don't understand what you mean by "compression" here ?
Is it because it's a screenshot of a video or something ?
I don't see how compression can make something "realistic"

[scarlet hull]

Then indeed, screen space to raytraced GI is your only way out

[vague steppe]

Compression is mostly visible on videos like from a phone or camera. By adding compression it looks similar to how a real life video would look

[pastel oracle]

Okay thanks! Will look into it

[vague steppe]

Thanks 👍

@shrewd moon where is the option to downsample?

[scarlet hull]

Maybe you could just fake this with a post process effect

[shrewd moon]

"Enable mip maps" generates smaller size mip map images, which you then sample in a shader by a LOD texture sampling function

I guess you can't get lossy compression for RT textures so you'll have to fake that anyhow

[vague steppe]

yea, but i sadly dont know how to fake it or how to even make a shader

[random maple]

what is the main reason to use hdrp over urp? what can hdrp that urp can´t, i am trying to choose a rp but i am not sure why i should go for hdrp.

[scarlet hull]

If you want better realistic lighting and more lighting effects, HDRP is the way to go (unless you want to spend money on asset sotre URP extensions)

[random maple]

Ok this is what i was also expecting.

[pastel oracle]

Was looking into raytraced GI. When using raytraced you can't used static batched meshes anymore. Doesn't this drastically reduce frame rate?

[scarlet hull]

This greatly depends on the use case :/

[smoky tide]

how come a light behind the wall is reflecting on the ground through that wall

[pastel oracle]

Yeah in my case it's quite bad 😄 I'm loading BIM files into HDRP so they are often very big. Static batching is my biggest performance gain

you said that Enlighten is deprecated but shouldn't it still work now? Or is it being phased out?

[scarlet hull]

Is that light "inside" the mesh. Then the polygon likely don't project shadows as they are backface culled in the shadow pass.
You can force double sided shadows on the mesh renderer component

[scarlet hull]

It shouldn't work iirc. I would just not risk it

[smoky tide]

there aint no light

in the mesh

its just behind a wall

[pastel oracle]

Okay thanks for the help! I'm gonna mess a bit more with ssgi then but I just can't seem to get good results with it

[scarlet hull]

Isn't it the light the appears to be on the ground that shows this specular effect then ?

[smoky tide]

that light is not in the ground

its underneath because its on the ground floor

i solved this issue somehow before but i cant remember because it was in urp

the light is casting reflections through a wall and that is my problem rn

[scarlet hull]

100% sure it's that light ? Because I see that it is projecting shadows, so it should just not light this area.

[smoky tide]

you are right its somehow the light underneath

this thing

[scarlet hull]

Is that light also projecting shadows ?
Is there any "thickness" between the ceiling and the floor ?

[smoky tide]

there is thickness of about 1 unit

[smoky tide]

i did not know that by default these lights dont project shadows

[scarlet hull]

Point light shadow is one of the most performance intensive, so it is disabled by default.

[digital spire]

Is it because it render 6 shadowmap? Are there any other reason?

[scarlet hull]

Exactly because it renders 6 shadowmaps 🙂

[trim stirrup]

has anyone noticed an FPS difference when using OnDemand lighting? I'm updating every 10 frames but there really is no difference between OnDemand & Realtime. Also, if I remove my script to update OnDemand lights, do they effectively behave like OnEnable lights? Thanks

[scarlet hull]

To be sure you'd need to dig in the profiler, maybe your shadow passed were not taking so much time at all

[trim stirrup]

possibly. i've been trying to knock down the influence of shadows on my fps without losing too much. looking at the profiler you realize how heavy HDRP really is

[misty portal]

I have a doubt about skinned mesh renderers.

I have a modular character system and characters can have up to 8 skinned mesh each (for equipments).

I can try to combine all 8 into a single model (and atlas texture) but my game is GPU bound and using only like 0,8% CPU while full GPU usage.

Is Render Thread time on unity actually GPU usage or CPU (a thread of cpu?)

Do more skinned mesh renderers use more GPU or more CPU? or both?

Is merging skinned mesh renderers worth it if i am gpu bound?

[knotty lily]

For every performance problem you should profile first to determine all hotspots and then decide what to do next. As for SkinnedMeshRenderers they are pure GPU entity alone (without animations). Mesh skinning preformed on GPU, and then rendering has no difference from ordinary (non-skinned) meshes. I don't think that merging will help you to improve performance.

[misty portal]

i`m using CPU skinning because my GPU is the bottleneck

[scarlet abyss]

Hey! Is there anyone here that knows what might be causing this glitchy look? It's HDRP in 2023.1.1f1 on apple silicon

[shrewd moon]

Can't recognize the problem, but 2023.1.1f1 is a few patches behind
That can make a big difference with tech stream releases

[scarlet abyss]

Ah, thanks, I'll check if the latest version has the same issues 🙂

That actually fixed it, cheers

[signal osprey]

how is retracing behaving in game? i read that dx12 in unity is super spikey

[loud leaf]

DX12 is a little slower than DX11, but not as bad as it used to be. Ray tracing is "ok" but has been broken in VR since summer 2021 or 2022, I don't even remember, but way too long.

It is just a single bug, and it shouldn't be too hard to fix (it's working fine in editor, just not in standalone), but it is not getting picked up.

The default ray tracing implementation is pretty inefficient and slow, but if you are willing to take the performance hit and rely on denoisers, it is usable.

[harsh basalt]

The performance of ray tracing and DX12 on my computer are pretty well

No lag if you keep everything in one bounce

Uh...

[eternal laurel]

Zfight on the geometry idk. You need to provide way more details. Also why do you have 6 directional lights?

thx

[loud leaf]

It seems the entire SAMPLE_TEXTURECUBE_ARRAY_LOD / SampleSkyTexture have been broken in single pass instanced for a long time. How is this not giving issues for more people? 😅 I ported 2021 HDRP to 2023.1 editor tonight as a last resort, but also trying to get to the bottom of the issue in 2023.1/staging because I don't want to give up.

After making 2021 HDRP compatible with 2023.1 editor, everything's fine, the issue isn't there, but it's missing other important fixes that would need cherry picking. I could check out at random commits (and there's a lot) to confirm which one broke it, but I would have to make the package compatible with 2023.1 editor after every checkout.

Multi pass is fine, but the slices of the sky are all "shuffled" in single pass instanced mode, after a certain HDRP date.

[long scarab]

there are actually many, many bugs in single pass instanced with HDRP. Water refraction, Line Renderer, some weird DLSS stuff ....

[loud leaf]

If the problem is that they don't have any actual devices in office, they could borrow my cheap quest 1 for a day, takes like 4 minutes to make a standalone build and see what's wrong. 😅

[long scarab]

Lol, exactly what I was thinking. Just donate some device. I'd also do it if this means stuff gets fixed anytime soon.

[weary quarry]

why do my shadows look like this? ive tried copying the shadow settings from the hdrp sample scene

[fluid merlin]

Looks like shadow resolution. Shadow resolution varies, under project settings check which Quality HDRP profile you're using. Then look at that those settings, under the Lighting section, check shadows and see what your resolutions are set to, in particular max resolution. Also mind what your shadow quality is set to on the light creating the shadows. The higher the resolution, the less pixelated shadows will be (the exception is baked lighting which is whole other mess of settings)

[worthy escarp]

I want to make a realistic daylight cycle, but I just can't seem to get the sunrises and sunsets right because I also want my noon sky to be an average blue sky. How do I change the sky and lighting based on the time of day?

[fluid merlin]

Not sure what sky type you're dealing with, but Physically Based is the one that gives you the sunrise/sunset coloring with varied exposure

[worthy escarp]

Yeah, I know. I was wondering how I could adjust that.

But also, my sibling took over my PC, so now I can't get back to the project that I need help with. This is gonna have to be saved for later.

[fluid merlin]

One option is to use the Advanced setting, enable "space emission texture" and "emission multiplier" then set an HDRI for the texture to the one you want for noon. As the directional light rotation on the X axis is in a range (90 for noon), you can increase the emission multiplier to fade in/fade out the HDRI with whatever represents the best noon etc. You can also swap out the HDRI for sunrise, sunset as well. This is what a blended procedural sky using an HDRI texture can look like:
https://i.imgur.com/cehE0vx.jpg

I'm sure there's other tricks you could use as well... however, what doesn't work well is swapping sky volumes (two volmes with different sky types and changing the weight between the two) in 2021.3... it's very buggy if you do that.

[loud leaf]

So far I am all the way back at february 16 2022 (7ab2be6888d32f94d324d328307cb283000b7f37), where it's still broken. If anyone wants to help debug this, that would be great. Basically pick a random SRP repo timestamp, start a HDRP VR project, enable ray traced reflections, pick a HDRI sky, and put a reflective sphere in your scene. Look at the sphere and observe, you'll notice if it's completely broken.

The bug is not Editor or OpenXR version dependent.

2021 HDRP will show you the correct result, aka this:

Recent HDRP (or anything after 2021 it seems) will show you this:

[worthy escarp]

I'm using physically based skies. I'm also using the 2022 family of versions. HDRIs seem like the easy way out of this, so I want to use the physically based skies for this one.

I was mainly wondering how property sunsets could be achieved using one sky volume while also having the daylight cycle going on. I also already set up the space stuff to be the stars during the night hours.

[worthy escarp]

Looks like I'm gonna have to do it on my own.

[fluid merlin]

Unity is sorta like that…

[digital spire]

have u tried creating 2 volume, one for noon, one for sunset and lerp between them base on Directional Light angle?

[worthy escarp]

Okay, I literally have no idea how to do that. I'm not THAT good at coding.

In fact, I'm not good at scripting at all.

[digital spire]

I just tried it for you, it work but the perf drop is insane

[meager mist]

Hey all, so I'm a complete noob when it comes to lighting... I'm using HDRP 14. My scene is real time lighting, with a physically based sky (its a fairly large outdoor environment and cycles through day/night hence real time requirement). I've got a static building that has a baked reflection probe which is making the room dark (which is what I'm after as otherwise, the skybox leaks into the room). My problem is when the character enters the room, hes a beacon of light, and I'm frankly unsure why. Can anyone point me in the right direction? To confirm, hes not stood in the sunlight entering the room... hes in the shadows 🤣

[minor depot]

Try throwing in an adaptive probe volume and baking it

[leaden light]

(Ignore the terrain and road, I am still working on these shaders)
I think the lighting, sky and car look absolutley good

It's all completly realtime, since its a racing game, I also optimized it for performance!

[haughty otter]

whats this line in the hdri

[shrewd moon]

Mip map

[inland star]

are APVs affected by realtime GI in any way, or is that a no-go?

[meager mist]

For the life of me I cannot make a closed box completely dark inside. Its forever picking up light from the main directional light. I've tried SSGI / Raytracing, but never seem to be able to completely drop the light out. Using an indirect lighting controller works, but not for the right reasons. Anyone know of any working tutorials for hdrp 14 as I must be misunderstanding this!

[fluid merlin]

Ahh... yes. So if you're familiar with Godot or Unreal Lumen, this is a bit of a pickle. My suggestion is to use non-reflective surfaces on the inside (if you using a unity white cube, make a new material, set the metal and smooth to 0) assign it all the cubes. Mark them as static, put a reflection probe in the middle and set the bounds to the inside of the closed space, bake the probe, bake the lighting. On the directional light, enable the contact shadows (helps with the light leaks a bit). It should now be dark inside...

[meager mist]

Appreciate the reply @fluid merlin . In practical terms though this wouldn’t be something you could apply in game? If it wasn’t a perfect box for example, say a house with a pitched roof, and the materials of the interior couldn’t have zero metallic and zero smoothness? Also I didn’t mention I need real time lighting as I’m working with full day night cycle

[fossil nacelle]

Is post processing done on the cpu? Im getting 100 fps with only 10% of my gpu being used. (this is on the main menu with only hdrp water, ui, and a single mesh renderer)

[scarlet hull]

No, GPU

[fossil nacelle]

so why am I being cpu limited when almost nothing is happening?

[scarlet hull]

Is CPU running at 100% ?
Do you have VSync enabled maybe ?

[fossil nacelle]

Vsync is off, the main thread is being maxed out and the render thread is being partially used

[fluid merlin]

Right, I know exactly what you're talking about, I just wanted to give you the very simple situation there. There's good news and bad news.... the good news is that yes, you can do it in Unity HDRP. The bad news is that, what you're talking about, everyone dealing with this situation has been asking Unity to address for years. Other game engines deal with this situation with SDF based lighting (SDFGI in Godot and Lumen in Unreal). Unity doesn't have that but it's trying to get there in the future with something they're calling Precomputed Realtime GI with Dynamic APV and it's still in development for a future release of Unity.

You can hack out a middle solution with SSGI, a real-time reflection probe, and the indirect lighting controller. There's an example of it here: https://www.youtube.com/watch?v=rBqA4ze3Qis

You can use Adaptive Probe Volumes but you need to setup lighting scenarios and fuss with the APV a bit to pull it off.
https://www.youtube.com/watch?v=Kcsid4DsH4I

Like all things gamedev and Unity, start by asking yourself, how important is this to gameplay? If the realtime aspects aren't ultra critical, avoid them in gameplay. If you're just experimenting and messing around, go with the APV route... you'll find a bunch a tutorials on using it, but you'll hit some pitfalls with dynamic lighting situations until PRGI/Dynamic APV is released.

[meager mist]

Appreciate the repliy. CAme across that first video a while back. It works, but there are some edge case scenerios where exposure goes a bit out of whack so I wrote it off as a workable solution. I've been fiddling with APV / SSGI combo and actually getting pretty decent results in a little test environment. Question is how it acts on a larger scale but I'll cross that shortly.

[fluid merlin]

No worries... Yeah, the struggle is real, many other developers have been in this same situation. I think most developers have been shying away from doing a lot of dynamic world indoor/outdoor scene lighting due to the current limitations.

[meager mist]

Yea, real shame

[topaz ravine]

I advice you all to try SSGI/adaptative probe volume

[topaz ravine]

RTGI is the best approach indoor, but is limited to 2000+ Nvidia series but it run nicely, however, if you don't want RTX, but you still nee GI, another feature is adapative probe volume allow to have no lightmap, it will give you the finest GI you need inside buildings or caves and the combo with SSGI is very nice, while outside buildings you can left no adapative probe volume, so the ambiant will be given by the sky probe and with SSGI, again, it's fine, you can even place adaptative probes outside, in open space area, into volume that count a lot less probes by meter, it will work too but consume memory without adding so much, there can even be lights liking, so I prefer not.
Note : lightmapping still work, so you can (third option) go for old lightmap's lightprobes: setup all your scene object use light probes, so you bake yourscene, but as result there is only light probe data (which will help SSGI) and so this setup can run on 1050-1060 or equivalent

[shrewd moon]

What do you mean the indirect light controller doesn't "work for the right reasons"?
It does work but you also need a reflection probe
I don't recommend trying to tweak material properties in an effort to "control" ambient lighting

If you want specific kind of indirect lighting instead of simply disabling it with the indirect lighting controller, then you need baked lightmaps, light probes or APVs

Those won't be realtime, unless you lerp between them
APVs might have had some option for smoothly swapping between lighting scenarios, but lightmaps or light probes do not (unless you make one yourself)

SSGI and RTGI from what I've seen can't handle all the lighting on their own, but rather supplement other types of lighting

[topaz ravine]

agree with Spazi, the fontainebleau project (a bit old) have lighting scenario for lightmap's light probe if some are curious

RTGI alone* with good parameter is not that bad, but it is heavy on gpu

the most ez option for beginners in HDRP is to stick with SSGI, the sky set to dynamic, no bake, then use the exposure correction when entering a indoor space

with some reflection probes it will be fast and work without any weird graphics behavior

outside scene using the ez option I mentionned (low cost lighting) : https://youtu.be/eXCHsgZbSEw

[open tree]

I made this interactive water shader that uses render texture to get information from the scene. I use red channel for the wave starting point, and green channel as obstacle which will reflect the wave. I created this simple Rain VFX graph where rain drops (marked blue) will collide with the plane and spawn the red particles(marked red). Red particles are working as source to create ripples on water. Now I want the Blue particles to be visible in the main camera but not the red one, and only the red one should be visible in render texture camera. How do I achieve that? Is there any way to separate them in layers or is there any way to link 2 visual effects?

I asked this in VFX graph channel, but dont think anybody knows the solution there

[alpine patrol]

Hi, i created a minimap with a second camera and render texture. The second camera only renders one layer with only 2 sprites nothing else, no geometry or volumes, but the performance still goes down about 20-25 fps and setpass calls are doubling and I also get 50 additional batches. I have no idea why, I thought rendering almost nothing would also take almost no performance...
Does anybody know what might be the problem here?

[distant hazel]

You should never ever have more than one camera per frame in srp. Use a draw objects custom pass instead

[alpine patrol]

Ok imma look into that, thanks 🙂

[distant hazel]

Specifically you can use CustomPassUtils.DrawFromCamera()

[fluid merlin]

I took a slightly different approach to the minimap situation. I used ScreenCapture.CaptureScreenshot on a map camera to write the bytes to a rawimage for the map (centered on level, orthographic, etc). then just enabled/disabled the camera when the map was needed. I then scroll the image in the mask relative to the player being center, this way you don't have to get a new image, unless you want one for a particular reason (major map change, etc).

[alpine patrol]

hm interesting, need to try that too

[digital spire]

https://www.youtube.com/watch?v=Z_8V-AkZNPg&t=10s this solution is also worth a try.

[waxen lantern]

true, and let's not forget amd radeon rx 6000 series and up (rdna2) support raytracing acceleration as well.

[twilit swift]

Hi, I'm looking for someone who can help me by just explaining to me some optimization tips for HDRP VR, like for example to prevent the objects to get blurry when you move the head or if the objects do.

[mossy solstice]

Disable depth of field ?

[mossy solstice]

Wait thats a thing ? I once had to trash a project of mine because i couldnt find a way to take a screenshot

[twilit swift]

Yes, but I want to know some more optimization tips, all Ik rn is light baking, occlussion culling/static batch. I know about impostors and other kind of optimization tips but maybe only 1 more and Idk how to make them.

[waxen lantern]

replied to this in #✨┃vfx-and-particles

[sour scroll]

why are the shadows doing this

how do i smooth the transition or something

so its not high quality to low quality

also none of my materials have previews

[fluid merlin]

Yeah it was added in 2017.1
https://docs.unity3d.com/ScriptReference/ScreenCapture.CaptureScreenshot.html

[digital spire]

did Unity just silently ghost the public Graphic Repo It's been a month since anything landed

[buoyant drum]

few scenes ive been working on and I wanna give it more realistic looks. 1st picture really needs it, any tips for that one? 2nd is alright but could probably just use more detail.
On the 3rd I know the concrete pillar textures have a noticeable repeat, is there any good material tile blending shaders and things? I dont know anything about making shaders. I also wanted to ask about reflection probes, having loads with whatever blend distance looks weird at certain angles and having one big one just makes the reflections very unrealistic. Whats the best way to go about that?
Another question I have is are there any packages that add more post processing effects?

[misty portal]

I have tried all fog parameters but i can`t get the fog to look like this

How to get this look (fog) with HDRP?

It looks like it has fog only far from player but not near

Is it even possible with unity HDRP native fog?

[fluid merlin]

Either way, it looks really good. It's often "too hard" to make unity look realistic versus the stylized look that Unity seems all too predisposed to render for. As far as reflection probes at distance, there's no really good way to go about it. I've seen some people that have used a custom shader where the shader allows you to use a cubemap in it. One of the puddle shaders uses that method. If you haven't already, hit up youtube for ArchViz HDRP tutorials, there's a few there that are good for some lighting tweaks

[buoyant drum]

Ty will check it out

[fluid merlin]

"Sort of" is the true answer.... sadly in HDRP, the distance fog no longer allows you to make a fog of war. There's a couple of options though, first is using Local Volumetric Fog with a 3D Fog Noise Texture and apply a scroll speed, you might be able to modify the texture in the shape of a torus and center it on the player. The other option would be to look at localized Unity HDRP clouds, there might be a way to use those to achieve the same effect. Third, I think there's an asset called InfiniCLOUD that allows you to do true Fog of War around the player, but you might want to research that a bit further.

An example using global fog and then using local fog with a texture applied

[misty portal]

Do your local fog follows player?

[fluid merlin]

You have to code it as such... you can put it at a distance in worldspace, then just lerp it in a coroutine so that it moves over time... You could then get a little fancier and dynimacally adjust the blend distance while it's lerping to stay around the player so it fades in/out a bit while the player is moving so it doesn't stagger

[sour scroll]

can someone drop these into their project and experiment a bit with them, using linear mode the water looks fine but after a friend changed a lot of stuff iwth hdrp the exponential mode isnt really working

im following this
https://ameye.dev/notes/stylized-water-shader/

the file name got cut off for the last one

shadersubgraph

its supposed to show a constant depth unaffected by camera movement, with high points being white and black being deeper

[sour scroll]

how do i disble a custom render texture

[buoyant drum]

found a way around it. Think I'll keep this scene as it is now

Just need to find out why some lights dont seem to give off any realtime lighting despite them all being mixed

which ive noticed in multiple scenes

[eternal laurel]

I bet you are hitting the 4 mixed lights overlap limit when using shadowmask mode.

“If more than four lights overlap, any additional lights fall back to Baked Lighting. The baking system determines which lights fall back to Baked Lighting, and this stays consistent across bakes, unless you modify one of the overlapping lights. Light Probes also receive the same information for up to four lights.

Unity computes light overlapping independently of shadow receiving objects. So, an object can get the influence of ten different mixed lights all from the same Shadowmask/Probe channel, as long as those light bounding volumes don’t overlap at any point in space. If some lights overlap then Unity uses more channels. And, if a light does overlap while all four channels are already in use, that light falls back to fully baked.” From the docs https://docs.unity.cn/ru/2020.2/Manual/LightMode-Mixed-Shadowmask.html

[misty portal]

@fluid merlin i got something with local volumetric fog and custom shader:

[buoyant drum]

Thank you and yes most likely.

I take it I gotta use light probes

[eternal laurel]

Just fix the overlap

[buoyant drum]

Only way for that is taking down the range though?

[dawn sorrel]

2 Issues here, I'm using local volumetric clouds, and if I fly into them, I can see below me easily, like there is a cylinder of wind around the camera. The other issue is that the terrain renders on top of the clouds. I'm trying to make a scene where you ar eflying through storms, so thiss kinda fucks it up

[unique coyote]

Does anyone know why a reflection probe would cause my editor to slow down?

Here is my settings.

I am using Unity 2022.3.6f1 HDRP.

[rotund ridge]

That's some massive box size

Not sure it could be the cause tho

[unique coyote]

It is my only reflection probe that is part of Enviro 3 prefab. It supposed to be a global reflection probe.

What should the size be?

[haughty otter]

anyone know how to fix this line in the skybox?

[fluid merlin]

Sort of looks like UI perhaps? Try turning off the UI layer and see if goes away

[digital spire]

it is realtime

maybe checking the timeslicing would help

also, check the render setting of ref probe and remove pass or effect that you won't need / have lower impact on the result

[unique coyote]

I will give it a try thank you.

[haughty otter]

worked thanks!

[scarlet hull]

To be able to fly through the volumetric clouds, you need to enable "local volumetric clouds" in the volume settings, else they are rendered with the skybox (so, behind everything else)

[shrewd moon]

I think usually this is because of mip maps or because of wrong wrap mode

[dawn sorrel]

I have done that, i believe the issue was with custom post processing from Enviro 3, a tool I use

[jagged belfry]

this is so cool

Baked lighting with light probes and reflection probes
Or just reflection probes and an indirect lighting override controller volume if you don't want the bake workflow

[pulsar skiff]

hi lads, im trying to get first person viewmodels working in hdrp and i followed this tutorial : https://www.intetic.com/blogs/unity-hdrp-render-object-on-top-of-everything/
which was recomended to me on this discord server and i also saw people saying it works on the unity fourms,
but when i tried it i got this weird effect where ssao and decals peeked through my model. any suggesgions on how i can fix this?

[pulsar skiff]

please help me :(

[twilit swift]

For some reason baked isn't working correctly for me.

[shrewd moon]

Well are you sure you did it right?

Followed all the instructions?

[twilit swift]

I did exactly the same thing I did in other projects but now when I bake mixed lighting It only bakes one or two lights and also makes some objects not get bounces or lighting.

[shrewd moon]

That sounds like problems with mesh lightmap UVs but it's hard to guess from here

[twilit swift]

Maybe I've skip something, but I'm not sure, I did the same from the other project...

[fluid merlin]

Super common problem, also a lot depends on your use case for the scene. For closed rooms where it's 100% dark inside and the player is moving between those those two... SSGI & reflection probes. Someone had a similar situation last week:
#archived-hdrp message

😅 TLDR: https://www.youtube.com/watch?v=rBqA4ze3Qis

[twilit swift]

Thanks, it kinda worked, I had to modify other parameters too.

[fluid merlin]

Yeah, this is a complex issue for HDRP (much less Unity as a whole) since it's lighting model is a few years behind. Here's a great example (albeit unreal) what most people are looking for Unity to do very simply "out of the box" without complicated setup and configuration
https://www.youtube.com/watch?v=95BVWdq37Kc

Someone from Unity at a previous Unity event was showing the Dynamic APV with the "pre computed" real-time global illumination and it looks similar to what Unreal is doing there.

Supposedly a year or so away (maybe)

[night depot]

Any ideas how to make alpha blending with opaque mode? Or using expensive transparent mode is mandatory for that?

[buoyant drum]

someone help please I cant bake my scene at without fkin unity crashing. First my whole project gets its rendering deleted and now it keeps crashing when I try to bake and if it does then 16gb of memory doesnt seem to be enough for unity.
-152 mixed lighting point lights
turned off screen space reflections thinking that would help?

[fluid merlin]

If you’re using the latest version of Unity, it’s usually the least stable unless it’s an LTS version

[buoyant drum]

i have reinstalled this package does anyone know if it is what causes problems or not?

[buoyant drum]

it is

i was on one that isnt

so i switched to 2022.3.1f1

[fluid merlin]

Editor log might offer some clues

[buoyant drum]

is that this?
