[keen bay]

im not very good with shader, can anyone tell me why this glass material let me see through wall?

[eternal kestrel]

ok today is not my day. How do I make this gradient horizontally wavy?

I'm drawing a complete blank for some reason

like I practically just wanna apply a sine curve to that line

[eternal kestrel]

ok I sorta managed it, am I overcomplicating this?

[eternal kestrel]

I deleted a node connection and unity crashed bruh

[eager folio]

What is the end goal?

[eternal kestrel]

ok so, what's the name of a sine wave that's completely comprised of straight lines

essentially, I want to make this effect spiky

oh I found out there's a thing called a sawtooth wave and it looks pretty much like what I'm trying to achieve

oop yeah that's it, problem solved

[untold forge]

Hey! Im using unity 2022.3.30 URP. I want to make a basic image effect shader. I did this a while ago with no issues but cant seem to get it workig now, how can i implement it? Dragging it in to the full screenpass renderer feature doesnt do anything... onrenderimage doesnt do anything... do i need my custom scriptable renderer feature to blit the screen or what? My shader is in CG
Figured it out.

[hot brook]

Hello there, I'm trying to change the code to use a gradient and blurring it instead of a texture for a toon shader in Shader Graph URP Unlit

this is my current setup

I would like to use a Sample Gradient, blurry it a little bit and then use it the same way but it does not receive the same params as Sample Texture obviously

[supple cove]

hey, does anyone here know how to use materialPropertyBlocks? I have an object and want to dynamically change its alpha, and i was just testing how the materialBlocks work and i just cant get it to work. I have this test script and it literally does nothing. I will also show you how the material is configured if that helps

[regal stag]

Gradient objects can't be exposed to the material and usually already blend between colours so a blur wouldn't be needed - and is an expensive operation anyway.
You'd be better off keeping it as a texture. If the problem is those are harder to create, Can probably find editor tools/C# scripts shared online to generate textures from a gradient from unity's inspector / custom editor window.

[regal stag]

_Main isn't a correct property name, you likely want _BaseColor based off looking at the Lit.shader source code.
However, using MaterialPropertyBlocks in URP is not recommended. You should set values on the material directly. e.g. meshRenderer.material.SetColor("_BaseColor", color)
(Or meshRenderer.sharedMaterial to reference the asset directly without creating a duplicate material)

[abstract dagger]

Hello guys, I need to generate a simple depth map in HDRP. I have a script that screenshots the scene. Anything in the docs about this? What is a good way of doing so?

[supple cove]

yes, but this either changes the color on all objects that use the material (sharedMaterial) or when just setting material, it instantiates a new material which is very bad for perfomance in my case, cuz i will have a lot of these materials

[regal stag]

URP uses SRP batching which optimises draw calls even with different materials, just needs to be the same shader (and shader variant - so same keywords set on material)

[supple cove]

yeah but the instantiation will still not be performant right? or does it not matter that much?

[regal stag]

Idk, maybe more memory but I doubt it would affect performance that much

[supple cove]

so i have one parent object and like 20 children objects under it that all have meshrenderers, so i made a new material on the parent object and change it dynamically how i want and then set the material on the child objects, but this changes the material on all the child objects even if just one calls it.

[hot brook]

How does skinner mesh works? Is there a way to use both textures in order to make an unlit shader based on that textures?

i tried blend node but with no success

if i put base color, only the head texture for example is drawn in whole 3d model and i dont want that

[regal stag]

The mesh has two submeshes, so you need to assign two materials. You should use a Texture2D property and connect that to the sample node. Then each material can have the appropriate texture assigned

[hot brook]

the thing is that i'm doing a Outline color material which is drawn on top of the material using Render Objects

[regal stag]

Make sure you use renderer.material, that should create an instance for that renderer so only that object is affected. If you use sharedMaterial or reference the Material directly it will change for all objects

[hot brook]

so i have to do two materials and stack them on top is the only way?

[stoic flint]

how is this even possible to render? anyone got idea?

[regal stag]

If you need data from the original materials you can use the "Override Shader" on the RenderObjects feature instead of "Override Material". The shader can then use the same property reference (e.g. "_BaseMap" if the original is using the URP/Lit.shader) to grab the texture.
Though be aware it won't batch objects so may be more expensive.

[stoic flint]

AO? useless, Raw geometry? only if u got 1000gb memory, normals? doesn't explain bumps + 1000gb memory

how do they render that realtime ?

[hot brook]

thank u so much i will try it

[hot brook]

i did, thnk u so much!

[ebon basin]

Mostly tessellation and controlling LOD. Most of those 'bumps' are not likely rendered till the camera is closer

[hot brook]

is there a way to cast shadows in unlit shader or lit shader in a way that only effect other objects and not itself? This is because I'm doing toon shader but I want the object still project it's shadow on the floor in some way (don't matter if manually or lit)

[ebon basin]

Depends.

Do you want shadows to affect the object at all?

[hot brook]

I only use Main Light Direction for the light computation in the unlit toon shader, but there's a bottom material which is drawing the textures which I change it to unlit in order to avoid it drawing the shadows of itself

[ebon basin]

Well, if you want an unlit shader with shadows you'll need to make a custom unlit and add the shadow libraries to it and the method calls

As for self-shadowing, you can turn off receiving shadows completely which would eliminate that but you won't be able to receive other shadows. If you do want to cast shadows and prevent self-shadowing while also recieving shadows, then there's some juggling with the renderer layers (light layers / shadow layers) you'll need to reseach into

[hot brook]

ok, thank u so much this looks a bit advance but maybe is the way to do it

[stoic flint]

low do you lod that ? also, doesn't tesselation increases vertices eitherway ?

so do u not need more memory?

also, in the video, the foot ik reacts to the very fine details

[ebon basin]

They're different chunks of meshes that are loaded at different times. Tesselation mapping / heightmapping helps reduce the overall cost of these meshes as it can be stored as a texture

[stoic flint]

i see i see, but the memory needed to render these verts remains the same as real verts no ?

and the cost ?

[ebon basin]

Most detailed chunk is rendered close to the camera, but those far back are using a lesser LOD that's less complex but because of shader magic it can appear complex

[stoic flint]

ah u mean the far things get the low mimaps of the displacement map ?

i get you

but its still very expensive to render such high count of verts

still

[ebon basin]

Stuffs actually pretty advance nowadays it might not even be chunking doing some advance texture streaming and mesh deformations

[stoic flint]

such as what

[ebon basin]

take a look into parallax mapping too, it's a pretty cool technique to fake tessellation when you further away

[stoic flint]

yea ik about it

not used here though

shadows appear really well at fine details from distance

[ebon basin]

really it's just all textures and interpolating the surface area between a handful of verts

[stoic flint]

@ebon basin idk about tesselation, i get pretty horrible results with very high vert count

maybe you mean sth else?

[ebon basin]

https://nedmakesgames.medium.com/mastering-tessellation-shaders-and-their-many-uses-in-unity-9caeb760150e

[stoic flint]

thank you for link but is can you comment the reason u sent it ?

[ebon basin]

It very much covers what I've said. Obviously it can be expensive but the article goes through different ways to lessen it through various methods

[woeful breach]

You should watch the new gta 6 trailer

[eternal kestrel]

ok I know I'm completely out of this conversation but that is exactly what I've been looking for yesterday

tyvm lmao

nvm it's a pain to implement in urp

hdrp has a tessellation node for shader graph but urp doesn't that's super annoying

ok so to confirm because I'm a little iffy on something

- sorting priority means that material gets rendered before others and + means it gets rendered after right?

What are we even looking at? What color does it have originally?

[halcyon plank]

Anyone might know why this is facing the wrong direction instead of at the camera

Seems like its inverted but i cant find out how to fix that

[humble geyser]

try return fixed4(1, 1, 1, 1) - col, 1 isn't a 4 dimensional vector

[stray gorge]

how can i get tex_texelsize in a hlsl function without passing through parameter ?

[zinc sequoia]

Hey, does anybody know how to get APV data in the shader graph?

Baked GI doesn't return anything

in this case

[stray gorge]

if u want to bake on runtime, my only idea is taking a render camera and a plane, if u dont bake in runtime then i recommend using blender to bake

[zinc sequoia]

im sorry you misunderstood me

what i mean is

the baked GI node in shader graph never shows anything other than black

i just want to access the data baked by APV

[hearty obsidian]

say I have global colors A, B, C. Is there a way that a single graph can point to any of those based on a per-material instance parameter?

e.g. different instances of materials of the same shader could point to either A, B or C depending on an exposed parameter

[regal stag]

Could pass those global colours into shaders using an array via Shader.SetGlobalVectorArray, though may need to take into account colorspace differences - (by using .gamma on the Color object on the C# side iirc?)
In graph would use an exposed float property, as input to a Custom Function node to declare & index that array. https://www.cyanilux.com/faq/#sg-arrays

But tbh, if you're exposing a parameter anyways, kinda feel like you might as well just expose a Color one. If you really need global colours can probably find a way to handle that on the C# side instead and set the color property with material.SetColor(...)

[glacial lantern]

Hey has anyone experienced this before? This white glow and black mesh is happening with any shaded material? This object was generated with code and it does not happen with normal meshes like the cube or plane. Is there some normals or uv thing that causes this effect?

ah ok it seems to be a normals issue. Im setting all normals to 0 by default, I guess for now I set to up by default should be fine, I wsn't ready for having normals compute yet in my code so yeah nvm

[amber saffron]

You could just add a quick RecalculateNormals at the end of the mesh generation 🤷‍♂️

[glacial lantern]

Yes and no. I was making a custom procedural mesh builder. As I was testing the mesh to see if the shape was correct it looked like that. I didn’t care about the shading yet but that glitch made it hard to tell if the mesh was being made correctly. But yeah anyways now I have the full thing, kinda like blender, full support for verts, edges, faces, and all that. And yes normals 😂

[grim bridge]

I don't know if this is the right chat for this but why do i get these artifacts when calling this function?

    void SetMaterialOnce()
    {
        Texture2D tex = img.sprite.texture;
        
        //tex.Apply();

        material.SetColor("_Color", color);
        material.SetFloat("_Radius", radius);
        material.SetFloat("_Blur", blur / 10f);
        material.SetFloat("_Alpha", opacity / 100f);
        material.SetTexture("_MainTex", tex);

        RenderTexture rendtex = RenderTexture.GetTemporary(tex.width, tex.height, 0);
        Graphics.Blit(tex, rendtex, material, 0);

        _shadow_img.texture = rendtex;
    }

The shader does gaussian blur and works as you can see, but those artifacts idk where they come from.

[low lichen]

This is either an issue in the shader or with your GPU. There's no problem in this script.

Well, there might an issue with using a temporary render texture and then keeping it around for a long time. If you need to use this texture for a while, you can't use a temporary texture.

[hushed silo]

i'm trying to do some basic lighting stuff in an amplify graph. specifically i am looking to sample a triplanar normal map from a light position to get a bit more depth in my material.

outputting the result is getting me diagonals through world space

here's my triplanar settings

any idea what I'm doing wrong?

logic is (or should be) normalize(lightpos - worldpos) , dot producted with the world sampling of normal map

[low lichen]

If the normal map has some directionality to it, like more streaks in one direction, then that would show up like this when it gets blended in three directions.

[low lichen]

Oh, you're talking about the angle of the shadow. Sorry, I was looking at the microdetails.

[hushed silo]

yeah, thanks. I think it's not a shadow either, just the result of some maths i don't undestand (this is on unlit shader)

[low lichen]

It's the shaded part of the basic Lambert lighting function you are doing (NdotL).

[hushed silo]

hmm. So it's trying to be from a point, rather than a direction, and has no distance sampling atm, so I don't know how its deciding that everything off that way is 'behind' so to speak

(the light position is in the middle of the room

[low lichen]

I think the problem is that you're expecting the Triplanar Sample node to return a world space normal direction, but it might just be returning the blended normal maps in tangent space. Could you try connecting the output from the Triplanar Sample node directly to color just to see what it looks like?

[hushed silo]

this is set to tangent space output

[low lichen]

Ok, the normal seems fine. Let's try visualizing the light direction after normalizing.

[low lichen]

Looks a bit strange. Are you hardcoding the position of the light in the shader? Or is it a property assigned from script?

[hushed silo]

from script with . it works fine for other aspects of the shaders lighting that i've already done

[grim bridge]

The problem is not with the shader, here is a sprite I applied the shader to.

Also here is what i get if i do Graphics.Blit(tex, rendtex); instead of Graphics.Blit(tex, rendtex, material, 0);

This is why i think this overload of blit Graphics.Blit(tex, rendtex, material, 0) does something wrong with shaders.

And I tried running the scene on a friend's pc with Windows but he has the same result.

[low lichen]

Did you see my second message, about the temporary render texture?

[grim bridge]

yes and i fixed it

[grim bridge]

Fixed it with this:

        var temp = RenderTexture.active;
        RenderTexture.active = rendtex;
        Texture2D texCopy = new Texture2D(rendtex.width, rendtex.height, TextureFormat.RGBA32, false);
        texCopy.ReadPixels(new Rect(0, 0, rendtex.width, rendtex.height), 0, 0);
        texCopy.Apply();

[grim bridge]

@low lichen I dont mean Ifixed my issues btw 😅 it's still there

[low lichen]

Can you share the shader code?

[grim bridge]

.shader file??

[low lichen]

Yes

[grim bridge]

i used a shader graph, so there is a lot in there that is not me

[low lichen]

Okay, can you share a screenshot of the shader graph then?

[grim bridge]

ok

[grim bridge]

i wrote the gaussianblur node myself

[low lichen]

Could you try plugging in some sampler into the custom function? Just a Sample State node with a Linear filter and Clamp wrap mode.

[grim bridge]

like so?

[low lichen]

Yes

[grim bridge]

what are you expecting it to do?

[low lichen]

Just see if it changes anything.

[grim bridge]

🥲

[low lichen]

I'm going to assume that means it didn't change anything. What type of shader graph is this? Unlit? Fullscreen?

[grim bridge]

unlit

also it's a 2d project so, maybe...

and i am using unity6.0

[low lichen]

Maybe try fullscreen, see if it does anything. You won't be able to use it on objects in the scene like now, only in the blit.

[grim bridge]

id't get it

[low lichen]

Change the shader type from Unlit to Fullscreen, in Graph Settings.

[grim bridge]

dude...

@low lichen|| WASSUP||

Omg thanks bro, how do you explain this?

[low lichen]

I don't know where those artifacts were coming from, but usually blit shaders are written a bit differently from shaders intended to be used in the scene. Unlit is for scene objects, Fullscreen is for blit shaders.

The graph type is just a different template Shader Graph uses when it converts your graph to shader code. Fullscreen has the right code for a blit shader.

[grim bridge]

thks

[hardy juniper]

Looks like its catching other sprites in the sheet, you need to manually add clamping to prevent it

[grim bridge]

yes, you mean in the custom fonction or directly in the graph? @hardy juniper

[hardy juniper]

where ever the sampling is done for the blur, the pos has to be clamped into the sprite uv region (you annoyingly have to add the uv min max range yourself)

[grim bridge]

is there a node for this? or is it hlsl

[hardy juniper]

can be done on either with min() or max() or clamp()

the point is to stop it sampling another sprite outside the sprite range

[grim bridge]

id'k get it i'm new with shaders

float2 sampleUV = uv + offset;
if (sampleUV.x < 0.0 || sampleUV.x > 1.0 || sampleUV.y < 0.0 || sampleUV.y > 1.0)
    continue;

fixed it thks

[hardy juniper]

You want to avoid if which is why we prefer min, max and clamp

I don't know enough to say if this would be optimised away for you

[hearty obsidian]

Thank you!

For the latter, I'm trying to dynamically test color schemes and I have tons of stuff creating instances of materials. If I change a color after the instantiation, then those instantiated materials aren't accounted for. Whereas if I use global vars, then instances or not, they're all pointing to the same location, making it a breeze without having to implement an event system across the board and without having to reference the materials anywhere.

[grim bridge]

void GaussianBlur_float(float2 uv, float radius, float blur, UnityTexture2D tex, float2 texel_size, UnitySamplerState samplr, out float4 result)
{
    if (radius == 0.0 || blur == 0.0) {
        result = tex.Sample(samplr, uv);
        return;
    }
    float4 color = float4(0, 0, 0, 0);

    float total_weight = 0.0;
    int kernel_size = int(radius * 2) + 1;

    [loop]
    for (int j = -1 * kernel_size; j <= kernel_size; j++)
    {
        [loop]
        for (int i = -1 * kernel_size; i <= kernel_size; i++)
        {
            float2 offset = float2(i, j) * texel_size;
            float2 sampleUV = uv + offset;
            if (sampleUV.x < 0.0 || sampleUV.x > 1.0 || sampleUV.y < 0.0 || sampleUV.y > 1.0)
                continue;
            float weight = GaussianWeight(i, j, blur);
            //float weight = GaussianWeight2D(float2(i,j), blur);
            color += tex.Sample(samplr, uv + offset) * weight;
            total_weight += weight;
        }
    }
    result = color / total_weight;
}

[hardy juniper]

Yes that's a shader alright

[candid tree]

im making a shader thats try to recreate an doom billboard sprite with a spritesheet.
someone know how to make this shader cast/receive shadows?

[cobalt wing]

Guys i want create the grid of XCOM, how i can do it?? I don't understand nothing of shaders

[stray gorge]

how can i keep this lighting effect from value bigger than 1 in game ?

[gloomy fractal]

is it possible to randomly scale the height of my grass

rn they have all same height but i wanted to add some variation by randomizing the height of the model

[grim bridge]

nvm it only works 1/2 times

I don't get it, this is so frustrating

[low lichen]

You could try clearing the texture before blitting to it. The blit should be overwriting the whole texture, but maybe it's not for some reason.

To clear the texture, after setting it as RenderTexture.active, call GL.Clear(true, true, Color.clear);

[grim bridge]

Before blitting? Isn't Blit() is called before RenderTexture.active?

[low lichen]

Right, I was looking at the code fix you posted. You'll have to also set it as the active render texture before the blit, so you can clear it.

[grim bridge]

GREAT, now it works, what is happening!?

[low lichen]

I see a potential issue with your gaussian blur function. In the end, you are doing this:
result = color / total_weight;

If total_weight is zero for some reason, you will be dividing by zero, which is undefined.

[grim bridge]

hum...

ok ok

[low lichen]

Whether total_weight can be zero depends on what GaussianWeight returns.

As a test, you can try ensuring you never divide by zero, by setting result to zero if total_weight is zero.

[cobalt wing]

Hey guys, sorry to interrupt your discussion, but I need some advice. If you take a look, the black borders seem a bit glitched because of the screen resolution. I wanted to see if Shader Graph could solve this issue. Do you think it would look better if I used shaders instead of the sprites I'm currently using?

[grim bridge]

If it's the screen resolution, I don't think using shaders would change anything.

Maybe PP can solve it

@low lichen the thing has been rendering smoothy for a lot of build now. idk even know what solved it

[cobalt wing]

what is PP

[grim bridge]

Pixel Perfect

[low lichen]

The glitchy look is aliasing. This is caused when you take high resolution textures and render them far away so they are higher density than the screen. This is normally solved with mip mapping, which is enabled by default on most textures, but I think maybe not for sprites, as they are normally used in 2D with sprites that can't get very small.

You can check if mip mapping is enabled on those textures and enable it if not.

Mip mapping generates lower resolution versions of a texture and automatically picks the best resolution depending on how far away it is from the camera.

[ebon basin]

Technically you're already using shaders with that ;p
But yeah that's actually a fine idea instead of making a shader specifically for drawing lines. Using unity's shaders you can just figure out the size and tiling needed and change those values inside of the material.

[gloomy fractal]

is there a way to random 2 colors for my grass?

it looks boring when the grass always has same color

[cobalt wing]

Not using sprites and instead switching to Default with mip mapping enabled seems to have worked. I don't think I'll dive into shaders for now. I'll just use different textures for each tile. Thanks for the help!

[dense bane]

did cubemap from refprobes change in unity 2022 compared to 2020?

[stray gorge]

instanced (property block Variable ) and gradient or random pixelate texture

[steel notch]

Hey sort of confused with something here. I have a basic flow map shader set up here. I am giving the shader a texture that has 0.5, 0.5, 0.5 in all channels, and yet I am still seeing movement.

Any idea what's going on?

I am using the UVFlowMap node included in Unity's Shader Graph Feature Example package, so I'm assuming the implementation is correct?

[steel notch]

Is this a float accuracy issue?

[amber saffron]

0.5 in all channels, I would expect a grey texture, but I see yellow ?

(or maybe you've imported it in RG format ?)
Also, double check that sRGB is disabled in the texture import settings 😄

[grizzled bolt]

Flowmaps only need RG don't they
If the texture is sampled as a normal map it probably should also be imported as a normal map

[amber saffron]

That graph doesn't seem to do the 0:1 to -1:1 remapping, so you might need to do it before

[grizzled bolt]

I assume sampling as type: normal should do that also?

[amber saffron]

(there shoud be a usage exemple to compare to)

[amber saffron]

Hum, yes, maybe.
Although a normal is supposed to be of unit vectors, so it "needs" a z value else you have a flow of constant speed in any direction.
IIRC Z is recalculated on the fly, so it might work.

[steel notch]

So the texture that came with the Feature Example package was this.

and this is the demo shader

[amber saffron]

So yes, sampling as normal indeed is enough. Double check that sRGB is disabled on your texture import settings.

[steel notch]

It is and I still get slight movements at areas where I set to 0.5. Even when I provide this texture to the sample material and up the strength to 50, it still moves.

[amber saffron]

Double check the pixel values ? Compression format ? else it might indeed be floating point imprecision 🤷‍♂️

[steel notch]

Does the "true" implementation have floating point issues?

Is the Unity sample implementation here wrong?

[amber saffron]

I'm a bit unsure here, the implementation is pretty standard, it's all more about how the pixel value is remapped.
8Bit values map 0:255 to 0:1. So the "real" 0.5 is 255/2 = 127.5 ... But this doesn't exist 😅

[steel notch]

oh god

which would actually produce a very slight movement

ya?

[amber saffron]

Yep, if your middle value is 128, it is slightly positive, so makes movement.

[steel notch]

jesus christ it all goes back to the 1970s

[amber saffron]

You could easily "hack" away this by doing some filtering on the flow map value though.

[steel notch]

wait how?

...is it subtract by 0.0039215686274509803921568627451

[grizzled bolt]

I can replicate the issue, 128 color values tug one way and 127 to the other
But how much is relative to strength and compression
At the default 2 strength it's not noticeable to me, even at low compression

[amber saffron]

Something like the following should nullify the imprecision
v = v * saturate( abs(v) * 128 )

[steel notch]

Even for the effect I was going, I didn't notice it until a friend pointed it out.

Said there was a slight ghosting on a small element.

Had to zoom in to notice it.

And now I'm down the rabbit hole.

[steel notch]

Sorry it's like 4am for me, why does this work?

[amber saffron]

saturate( abs(v) * 128 ) gives a 0:1 mask of the imprecision around the 0 value, and applying it to the flow value will force it to 0

[grizzled bolt]

This the right way to do it?
This one halves the flow amount for both 128 and 127 values, but doesn't eliminate it
subtracting 1/255 fully eliminates it

[amber saffron]

Halves .... hom, ok, maybe my maths don't properly math up :/
If subtracting 1/255 works, stick with it, but I think it assumes that the mid range value is 128/255, if for some reason you use 127/255 is might offset in the other way.

But 128/255 seems more correct to me.

[steel notch]

I don't think just subtracting 1/255 works I just kinda blurted that out. What's gonna happen is that you're going to get either a -1/255 or a 1/255 value when it SHOULD have been 0. So any values in that range need to be clamped to 0.

Actually, is it even standardized how programs handle a 0.5? Will some round up when mapping it to the 255 range?

Wait... does this mean that Normal Maps also have this problem? That the default value is actually slightly tilted because we can't get true 0.5?

[grizzled bolt]

Yea, in a real world scenario you'd have values roughly around 128 in places where the flow intensity is meant to be generally the lowest so subtracting causes a bit of a jump between 128 and 127
Tbh usually flow maps don't need to be that precise because the whole thing will be flowing

[steel notch]

I simply wanted an area with no flow >_>

[grizzled bolt]

Might want to lerp out the effect entirely in another step

[steel notch]

I had a picture of a ship on some waves and wanted the waves to move and the ship not to move.

[grizzled bolt]

Or map the flowmap to a curve so it becomes proportionally less intense around mid/0, and more extreme at the ends of the color range

[steel notch]

Do you guys have any good tools for making Flow Maps btw?

[grizzled bolt]

In this case imposing the ship on the waves separately would solve this issue, and also prevent the wave flow from sampling from the ship's pixels

[steel notch]

another texture sample 😛

[amber saffron]

Or use an other channel on the flow map to mask out the ship, connected to the flow speed

[steel notch]

holy big brain

[grizzled bolt]

Quite!

[steel notch]

I'm okay with doing a small clamp on the flow map to gt rid of hyper small values though.

Jesus what a world.

[grizzled bolt]

The ship and other objects separate from the background could also be geometry, with vertex colors or an atlased flow map if you need to get funky with it

[steel notch]

For a bit more context, this is actually a 2D image for a card back.

wait it would actually be values -1/512 an 1/512 right? Because it was the midpoint between 127 and 128, rounded to one of them, and then remaped to 0 to 1 when we're in shader land

So...

v = abs(v)
v = v * step(threshold, v)

I think?

Otherwise you do some branching stuff.

[amber saffron]

In pure code you'd be loosing the sign of V here, but yes, it's the logic.

[steel notch]

Ah true so just
v = v * step(threshold, abs(v))
right?

[karmic roost]

hello, ive spent forever hours trying to fix this but i just can't get it to work. does anyone know what is up with my normals? please ping me. Using URP

[grizzled bolt]

Textures not imported as type: normal map I would expect

[karmic roost]

they are

[grizzled bolt]

They have tangent space normal map data in them?

[karmic roost]

i assume

[grizzled bolt]

Could show them

[karmic roost]

its the almost purple textures

usual normal maps

[grizzled bolt]

With the import settings

[karmic roost]

sure give me a minute

@grizzled bolt there is in fact no normal texture plugged in

[stray gorge]

2d tree overlay shader, any tip for hide the trees behind the moutain ? (trees and the terrain currently are 2 object). The trees is just a plane

[grizzled bolt]

That was the issue I assume?

[karmic roost]

well, this texture isn't meant to have a normal texture, but i'd expect the triplanar map to work even if there's no normal

it would just be

a plain texture with no bumps

but the lighting issue persists

do you want me to show you the shader graph nodes¿

[hushed silo]

Is anyone able to tell me why the output of the highlighted node here

puts diagonal lines through my mesh? I'm trying to get a reaction from a point light to the normal map

[grizzled bolt]

The texture property needs to have mode: normal map so its default value is a neutral normal

[karmic roost]

how can i add a neutral normal? i didnt even know that existed

also this is happening
this material DOES have a normal map yet:
there is visible normal map stretching
weird jittery texture in those edgfes (i made sure there are no overlapping faces)
same angle shadow

[grizzled bolt]

Node settings of the texture property, though you wouldn't "add" it, just define what kind of default value to use when no texture is assigned to the property

[karmic roost]

Do i have to add a default texture, or change the mode...

i got the node settings here

[grizzled bolt]

Mode: normal map like I said
Default value can be none

[hushed silo]

actually I didn't set the texture to normal type in unity inspector 😓

[slate wasp]

I need some help with my 3D model, it doesnt appear to be culling properly, If i look at it from like a whole direction (lets say south) the model dissappears completely. I have to be looking at it from the North to be able to see it.

[hardy juniper]

can you send a video? hard to tell from just images

[slate wasp]

Sure, here:

[hardy juniper]

Hmm first thought is that it has bad bounds making it be culled too much

[low lichen]

The bounds of the skinned mesh renderer is probably incorrect.

[hardy juniper]

snap!

[slate wasp]

Goddammit, for some reason the Bounds are in the Origin coordinates while my model is moved. But if i move the model it messes with the positions of various things in the heriarchy

ok what is going on, if i move my 3Dmodel anywhere the Bound won´t follow!

[slate wasp]

thanks

Yeah there is some kind of problems with the bounds

[slate wasp]

Alright solved it by checking the "Update when Offscreen"

[serene condor]

hey, so i see that HDR colors aren't an option in sub shader graphs, is this the correct implementation ?

i see mixed discussion whether its the alpha channel is used as intensity multiplier, or if the raw vector values are just presented (like 5, 5, 5, 1). if i were to route in an HDR color into the "Emission color" input would this work the same as the standard emissive component?

it looks ok comparing side by side, but just doing a sanity check

[fresh flame]

any ideas where to start implementing this effect? What should I search for? I think it adds an outline to selected grid area? also what about the gradient going upwards

[serene condor]

Shader has to be in transparent mode, then you’d need a position node to orient the effect to take place from bottom to top if it’s supposed to animate. From there gradient on the alpha channel

[sharp mural]

Hey folks, wondering how I can reduce the reflection on the floor? It's using a simple triplanar shader I created by following a youtube tutorial

Not sure if the reflection would be changed on the MAT or inside the shader itself?

[eager folio]

What is it reflecting? Skybox? Light?

[grizzled bolt]

HDR colors go above 0-1 range, alpha is still alpha rather than exponent
I'm pretty sure

[sharp mural]

It's reflecting the spot light just above the statue

[eager folio]

Is it a pbr shader?

[sharp mural]

Honestly, I'm not too sure, I just copied a simple 'triplanar' shader tutorial on youtube

[grizzled bolt]

Decreasing smoothness reduces specular reflections
I'd say more than reduced smoothness it needs a normal map, and optionally smoothness map for it to actually look good
But that's up to your taste

[sharp mural]

Would you be able to point me in the right direction to reduce the smoothness?

Do i just reduce the 0.5 value of smoothness?

[grizzled bolt]

Yes

[sharp mural]

That's got it, Thanks heaps dude

[minor remnant]

How would I sample a texture that's set by CommandBuffer.SetGlobalTexture()?

I cant for the life of me find how to access it in a shader after setting it

[hardy juniper]

You may be moving the root bone vs the base transform for it all or something similar

[fresh flame]

I'm trying to keep edge line same size regardless object size, what am I doing wrong here?

[amber saffron]

My morning brain is unsure, but I think you need to multiply the edge width with the min(ddx, ddy), and use this to step the minimum of the gradients

[steel notch]

Keywords literally create shader variants right? Does that shit scale exponentially? Like if I have 1 boolean keyword, that's 2. If I have 2 keywords, 4 variants? If I have 3 keywords, 8 variants etc etc.

[amber saffron]

For boolean keyword, yes, that's how it works.

For enum, the values are mutually exclusive, so for a 4 enum keyword, that's 4 variants, not 16 (2^4)

[steel notch]

Makes sense. You still use the Enable/DisableKeyword method to toggle Enums, right? I found that you basically need to toggle all options at once to really get it to work. Like if you had A, B and C enum options and needed C, you would need to Disable A, Disable B and Enable C in code.

[steel notch]

On a separate note, I have a basic shader that's just layers 3 textures on top of eachother, but I want to be able to apply lots of effects to layer 1 and 3. Holographic effects, parallax, motion, glow etc etc.

So I was thinking about how to best set this up from an optimization perspective (why do all this work in cases where some of the effects aren't needed?) and a clean inspector so all the fields don't become a mess.

[frosty linden]

Hello, I'm trying to create a HDRP lit layered shader graph with alpha mask being in one separate texture property each instead of one packed texture so I can tile and offset them individually.

I don't understand how I'm supposed to use the branch node if I add more layers

Plus it also seems like I need to create branches for each of my values (color, ao, normal...) which is a lot of branch? Or am I missing something?

[frosty linden]

Ok nevermind, I've added the branchings directly inside the sub graphs, so 5 different branching (I'm using alpha from main layer as global alpha so no need branching for this property). I think that should be the normal way to do that. If there's a better way to handle branching, let me know.

[amber saffron]

Keywords are good for really stripping code of the shader but create variants as you know.
But sometimes, for enabling or disabling a feature a constant float value is enough. Use dynamic branches in the code (if(f > 0)) to toggle the feature, and because the float value is constant on the material, only one branch is evaluated. But it doesn't result in multiple variants.

As for the clean inspector, either write a custom inspector, or use something like shadergraph markdown to have more UI options

[amber saffron]

I see two options here for branching the layer count :

1. use a keyword enum which will create a nice 4 inputs 1 output node
2. use a custom function with a switch statement, similarly to have 4 inputs 1 output

For the ease of connections, you could also pack the surface data in a single 4x4 matrix.

[steel notch]

Let's say I'm sticking to shader graph. Does the same logic still apply with the Branch node? I thought branches were something avoid unless absolutely necessary.

[amber saffron]

Branches are bad when the different branches of a same condition need to be evaluated in a single wavefront (screen space pixels group, 16x16 or 32x32 iirc).
IE, when you use screen space noise to select between branch A and branch B. In that case the gpu group can properly optimize which branch to use for all pixels of the group, and needs to evaluate both for every pixel.

But is you use a constant value on the material for the branching, it knows that all pixels within a single group either use branch A or branch B, and can then only evaluate a single branch, without running the other one.

And yes, this also applies to shadergraph

[hardy juniper]

The branches should be controlling if only 1 layer is used OR if layer 1 and 2 are combined (e.g. by a mix/lerp). This will repeat till you have all layers combined (e.g. 1+2 combo combined with layer 3 ect)

[humble geyser]

where are these patterns coming from? I get them when trying to use normal from height in shader graph (for a height/displacement map)

[frosty linden]

So the branching would be out of the sub graph with this solution ?

[amber saffron]

Yes

[frosty linden]

And if the enum is set to one layer, then the 3 other layers won't be processed at all, making it more efficient, is that correct?

[amber saffron]

Yes

[frosty linden]

My current sub graph is like this, the branching for each property is inside and I'm currently using a float for the number of layers. But this way, all layers are processed which is inefficient if I understood correctly?

The only way to make it efficient is to use a keyword then?

(I've been using the lit mask map as my default albedo since I only use greyscale, and I put my grayscale albedo inside the mask map blue channel, replacing the details map which I don't need

[amber saffron]

Hum, if I'm not wrong the branching logic should still work.
Subgraphs are compiled into separate functions, and when being evaluated all the layer functions are called, but those for "unused" layers won't do anything.

[strange prairie]

Looks like clipping. Do you have duplicate geometry?

[frosty linden]

Hm, but the unused layers would still be evaluated then, won't that affect performances compared to using branches with a enum keyword outside of the sub graph like you said ?

Are all layers still evaluated even with the keyword ?

[amber saffron]

The function will be called, but because of the comparison it will just reroute the previous layer inputs, without doing anything more.
It should be that much of a performance hit.

But indeed, if you want to be sure that the function is not called, the branching needs to be done outside of the subgraph

If you want to squeeze even more performances, you might be interested in this layer packing technique : https://unity.com/blog/engine-platform/experimenting-with-shader-graph-doing-more-with-less

(also, I find it suspicious that you are using overlay blend between the layers)

[abstract dagger]

I'm trying to get a depth map from a screenshot that I take in game. How do I do this in Unity 6.1?

[frosty linden]

I haven't tested my shader yet actually, I was just assuming the default lit layered was already using overlay blend since it's the default option

Thanks for the link

[kind juniper]

Make a separate pass the renders the depth buffer to a render texture. Then save it to a file.

[frosty linden]

That was an interesting read. The dual color ramp method is actually a huge plus for grayscale albedo. I'm amazed by what people can think about to optimize stuff.

[abstract dagger]

do you mean the custom pass? i think unity now uses the render graph exclusively?

[kind juniper]

Yes. I don't think the render graph replaces the render pipeline passes. It's a tool for managing them from what I understand. But yeah, you can probably add a pass via the render graph too.

[abstract dagger]

hm. to be consistent I think i'd rather add the pass through the render graph. So I'm guessing I can trigger the render graph to apply the depth map shader and then save it? sorry if im asking too many questions

[kind juniper]

I assume so. I have very little understand of the render graph and generally render pipeline customization in the latest versions. You'll need to research it yourself.

I can tell you how that would work from the graphics API perspective:

• you bind the render texture render target to the pipeline
• bind whatever buffers and textures you need to the pipeline
• record a draw call with the specified shader that would draw the depth to the render target.
  Done.

[abstract dagger]

hm. ok thank you for your help. i will have to go more in depth

[steel notch]

What is a “constant value” in this case?

Like if I expose a float in the inspector. Is that a constant? What if I do operations on it before throwing it into a branch node?

[humble geyser]

I don't have duplicate geometry, it's a tessellated mesh. This issue appeared when I tried to use normal from height for another heightmap as well.

[cosmic thorn]

Is anyone else experiencing the shadowCaster bug with unity 6?
the compiler for me just gets stuck on compiling the shadowCaster and prevents me from testing my game.

[amber saffron]

Yes, a float exposed in the inspector is constant.
As in, constant over the whole object in the current frame.

[regal shuttle]

This here seems to be the place for culling issues. I believe my issue is simple but I still struggle with it. I'll have a video about it later (I'm short on time right now.) I'm actually working on a world for a game called VRChat but I think my issue is just basic / general enough. I'm tweaking Occlusion in my world and as you can see in my lil camera view, some things are not showing up. I did select very small object sizes, so those cubes should appear... even if they were too small, the big, darker box should definitely show up. I'm not entirely sure what's causing this issue. I can try smaller and smaller objects culling but it doesn't see to be the fix? Oddly enough, depending on where I'm looking, even if I'm right next to the button, sometimes they appear, sometimes they don't

[fresh flame]

is this what you meant

[amber saffron]

Yes

[fresh flame]

okay then it didn't work 😄

thanks though

sec

yeah its working, got another issue. thanks a lot!

[cobalt idol]

hi!

is it possible to use tessellation in URP?

and is it valid to use URP in 2025 anyway for a pc game?

I hate shader graph so much I just want to write my shaders but it seems URP is really limited and HDRP more or less demands using the shader graph?

[amber saffron]

is it possible to use tessellation in URP?
Technically, yes, if you are willing to hand write your shaders

and is it valid to use URP in 2025 anyway for a pc game?
Yes, even more if you plan on releasing on more platforms, aim for more stylized graphics or higher framerates. But you don't have as many features provided out of the box as in HDRP.

I hate shader graph so much I just want to write my shaders but it seems URP is really limited and HDRP more or less demands using the shader graph?
Is it still possible to hand write shaders with URP and HDRP, but it is drastically more complex than in built-in because there is not equivalent to surface shaders.

[minor remnant]

can someone give me a monkey brain example of how to use Graphics.CopyTexture with a CubemapArray? the docs only go over how to use the SetPixels() method

[low lichen]

What is the goal? CopyTexture is for copying in GPU memory, so it doesn't help for common goals like reading pixels in script or saving to disk.

[minor remnant]

I want to save reflection probe cubemaps to a CubemapArray so I can access them in any shader

basically sidestepping unity_SpecCube0 so I can sample multiple probes at once

[low lichen]

It's definitely possible to copy one face at a time into the array, can't find confirmation whether you can copy a whole cubemap in one call.

[minor remnant]

my current code is along the lines of

CubemapArray reflectionProbeArray = new CubemapArray(2048,8,TextureFormat.RGBAHalf,true);

///...

    void SetupReflections(CullingResults cullingResults)
    {
        NativeArray<VisibleReflectionProbe> visibleProbes = cullingResults.visibleReflectionProbes;
        if(visibleProbes.Length>0)
        {
            for(int i=0; i<visibleProbes.Length; i++)
            {
                VisibleReflectionProbe probe = visibleProbes[i];
                Graphics.CopyTexture(probe.texture,0,reflectionProbeArray,i);
            }
        }
    }

[low lichen]

All the cubemaps must be the same size and be a compatible texture format to work with CopyTexture.

I think you may also have to copy each mipmap individually.

[minor remnant]

rn im just prototyping so I dont necessarily need mipmaps

CopyTexture seems to throw some error about Graphics.CopyTexture called with null source texture

[cobalt idol]

ok thank you

I'm trying to understand how renderer features work(URP). Here, I full screen pass renderer that's taking in a material named "temp" with a shader named "temp". This should make the whole screen white, but it's not and I'm not sure why. Here's my shader code although I doubt that's relevant:
https://paste.mod.gg/cxwfgmahmvtb/0

[teal lynx]

When I create a new full screen pass feature, the default material inverts all the colors. I'm not sure what they're doing with that default material that I'm not doing here that makes their thing work.

[regal stag]

A specific vertex shader is needed to correctly draw the fullscreen triangle. See https://www.cyanilux.com/faq/#fullscreen-shader

[molten pike]

How do make my textures not pink?

[teal lynx]

Broken shader

[molten pike]

I know its a broken shader, i need help fixing this

[hardy juniper]

What render pipeline is the project using and what shaders on the broken materials?

A built in lit shader with urp for example will not work and be pink. Easy fix if this is the case.

[molten pike]

I think its 3d core render pipeline

[hardy juniper]

er probably built in renderer then. show shader on one of these materials here

[molten pike]

Here is one

[primal spruce]

anybody know whats causing this? I'm just trying to find a way to seamlessly scroll a noise texture in the shader graph across the surface of a sphere but this is the closest I've been able to get

[ebon basin]

Well, do you understand how UVs are mapped on the sphere, specifically Unity's sphere if that's what you're using?

[primal spruce]

yeah

worth noting that I'm trying to avoid UVs by putting the world position into the UV input for the noise

because UVs will always have a seam

[ebon basin]

usually I just use like local/world uvs for spheres if I'm just doing noise to get around the wrapping issues with em

[primal spruce]

yeah thats what I tried but it produces that weird distortion around the x axis specifically

[ebon basin]

but if that's what you're doing then carry on, just can't make out from the graph there lol

[primal spruce]

ahh lol, here are some better sc

[ebon basin]

Ah, yeah my shaders do still have somewhat a seam even with world UVs for the unity sphere, so there's probably a bit more to it

[primal spruce]

actually that gives me an idea, let me try a non-unity sphere and see if that works

better yet, I'll import a quadsphere so that the UVs can be even better

since I'm doing position I doubt it will change much but still

[ebon basin]

https://catlikecoding.com/unity/tutorials/procedural-meshes/uv-sphere/
Catlike has a way to use cubemaps which seems like an idea

[primal spruce]

oh damn, I'll have to take the time to read through that later

bruh now it just stretches on the z axis

[torpid vault]

Quick question for anybody who knows about optimization tricks -
what is the performance difference for wrap mode? Clamped vs Repeat?
I was just recommended to do an operation inside of an HLSL shader as opposed to setting the texture to repeat, citing it is slightly more performant. I'd like to know why / how but google is not giving me the deep lore I'm looking for

[kind juniper]

Who were you recommended by to do that?
These settings just change the sampler parameters. And you need a sampler in order to sample anything from a texture.
These settings just define how the sampler is sampling the texture(or rather where).
I really doubt there is any noticable difference in performance between these settings.
You're probably looking at the wrong thing to optimize.

The "deep lore" would depend heavily on the used graphics API. If you're going with d3d11/12, you should be looking at it's documentation. But there's very little info in terms of performance. Performance is also very context dependent.
If you really want to optimize, you should use dedicated profiling tools, like PIX, Nvidia Nsight(or whatever tool is native for your target platform), maybe render doc.

Before deep diving into shader optimization, I'd use the unity profiler to see where the bottleneck is in the first place.

Maybe there's a way better candidate for optimization.

[crisp radish]

im not sure if this is the right place to ask this cause i dont even know how you would accomplish this but how would one go about making a texture or shader like the clothes in chowder or stans jacket from monkey island? that thing where it seems like the texture is just a global background that dosnt move when the object its on does. i want to use it on a shirt for a 3d charicter model im making but i have no idea how to gow about it, these are decent examples of what im trying to accomplish https://youtu.be/htGt6frPSH0?t=76
https://youtu.be/STnYDchAn78

[grizzled bolt]

When the camera moves, the pattern does not move though

Is that important?

[torpid vault]

in house tech artist that used to work at unity.
I believe him but didnt have time to ask him to go in depth
it's also not an optimization stage. I hit a point where it was "2 options how to fix this development problem: Do an extra step in the shader or modify all our texture import settings" and he said do it in the shader. I'm just curious if there's a well known reason why, and it sounds like not 🤷

[frosty linden]

Hello, using hdrp shader graph, which blend node or similar node do I need to use to stack a texture on top of another, the black color being ignored and the whiter the top layer is, the more it replace the bottom layer texture.

Overlay and screen don't see to do that

[amber saffron]

A side effect of doing it in the shader is that you also need the manually compute the derivatives and sample with SampleGrad for proper mip level filtering.

[amber saffron]

"Overwrite" blend mode, or just the "Lerp" node.

[frosty linden]

Thanks! I thought it would also overwrite the black pixels

I've got a weird bug in my shader graph. The default value field does not appear at all. It's supposed to be a float. Is it fixable?

Even restarting Unity doesn't fix the bug

[regal stag]

You might have ticked the "Use Custom Binding" option under the property/input in the subgraph

(allows you to set a custom name rather than the regular input field - you'd usually use it with the Branch On Input Connection node)

[frosty linden]

That was it, I clicked by mistake, I didn't even know what it was used for lol. Thanks !

[sharp frost]

How can I use sprite Unlit shader on Overlay UI?

Its coming black.

on Screen Space - Camera its working fine but not working on "Overlay".

[regal stag]

There's a "Canvas" graph type in 2023.2+ and Unity6. Older versions didn't have proper UI support

[odd wraith]

I made a triplanar shader for my hdrp project. I found how to add a normal map but I can't find how to add a height map. Are height maps supported by shaders? That's what I have so far

[amber saffron]

The heigh map is either used for :

• Parallax mapping through the parallax node or parallax occlusion node. But it doesn't work well with triplanar and you might have to do your own implementation
• Vertex displacement with tesselation, in that case you need to enable tesselation on the shadergraph setting and make the displacement yourself in the vertex stage (position + normal * height)

[odd wraith]

so it would be better if I used vertex displacement right?

[amber saffron]

Probably easier to setup.

[odd wraith]

I put the position + normal * height here?

also when you say normal * height normal map * height map or normal map * the depth I want?

[amber saffron]

vertex normal * heightmap value * amplitude multiplier

[odd wraith]

is that a node that I need to activate somewhere

[amber saffron]

"Normal Vector" node

[odd wraith]

thanks

Do I multiply these and then add the position

[amber saffron]

Why do you want to multiply the normal vector by the "normal from texture" ?

[odd wraith]

It wasn't letting me put the texture in directly

[amber saffron]

Sample the height map with the "Sample Texture 2D LOD" node (as the regular sample texture 2D doesn't work in the vertex stage).

[odd wraith]

so like this do I set it as normal or like this. Also is the position good

[amber saffron]

Normal and Position nodes should be in "Object" mode, else it seems good.

[amber saffron]

Ah stop, no, I always forget that for tesselation it is a displacement that is connected, not the final position.
So remove the "add position"

[odd wraith]

wdym just attach the multiply immediately?

[amber saffron]

Yes

[odd wraith]

did I select the wrong things?

[sharp frost]

Thanks for the information. Is there any other way to use shader graph on Canvas?

[amber saffron]

I don't think so.
I don't know what your displacement texture and tesselations settings look like, but what is here is a possible outcome.

[amber saffron]

"Tessellation Mode" = "None" ? 🙂

[odd wraith]

woops

It still stayed the same

increasing the phong thing

[amber saffron]

Well, should still be ok, the phong tesselation is for smoothing geometry

[odd wraith]

should I send a pic of all the shader graph

I might have messed somethng up

It's texture on top, normal in the middle and heigh map on the bottom

[amber saffron]

Normal Vector node should use "Object" space.

What does the height map look like ?

[odd wraith]

and the textuer on too?

wait I had the wrong height map selected let me send a pic

it fixed with the normal thing

[amber saffron]

"Tessellation Factor" is the amount of times the geometry is subdivided to have smaller vertex deformation.
1 means that fron the 1 quad face you end with 4. Wich is probably not enough for the texture that I can see.

[odd wraith]

this was the correct height map

[odd wraith]

let me increase it also how can I add a custom depth too

[amber saffron]

What do you mean by "custom depth" ?

[odd wraith]

as in I can choose a value for the depth of the heigh map

height

[amber saffron]

Expose a float parameter on the shader and multiply it with the normal*depth

[odd wraith]

so after the first multiply I add the float I had

[amber saffron]

not add, multiply

[odd wraith]

sorry multipy I meant

[amber saffron]

heihtmap value * float height * normal

[odd wraith]

It doesn't seem to be having an effect

shoudl I try increase the tesselation factor right now I put it as 4

[amber saffron]

Maybe even more, your are starting from a very low polycount

[odd wraith]

what's a good average number to start the testing>

[amber saffron]

I can't give a magic number here, it can depend of many things.

• the "minimum triangle size" limits the amout of tesselation for a single triangle isn't smaller than X pixels on screen.

[odd wraith]

so I just put a bunch of random numbers if it gets better I stick close to those numbers

and are there any big downsides to having a big number

[amber saffron]

It will increase rendering cost.

[odd wraith]

its looking like this?

[amber saffron]

Interesting, it looks inverted. But it's definitively doing something and I can distinguish the heightmap shape here.

[odd wraith]

That's me trying to offset it inwards cause the normal height map that's what it was doing but this one feels off when I go the other way round it offsets the planks in a detached style and in the wrong places

I'm trying to mimic the block next to it

so I can have an easily tileable version of it

[amber saffron]

The "detached style" is expected because the cube mesh has "hard edges" : eight cube face ha a normal pointing in a different direction, so it is "pushing" the displacement along it, resulting in the holes at the edges where each face is pushed in a different direction.

[odd wraith]

yeah that makes sense. That's why I was trying to give a -depth

but at the same time it shouldn't be leaving the height map at that point

could it be I need to also apply the triplanar to it?

[amber saffron]

Also, the displacement is not matching the color/normal maps because the displacement texture is sampled using the UV, when the other ones are using triplanar.
Sadly, you can use the triplanar node in the vertex stage and would have to recreate the triplanar logic with multiple "Sample Texture 2D LOD" nodes for it to match.

[odd wraith]

true

triplanar is a vector 4 tesselation is a vector 3

[amber saffron]

Triplanar vector 4 output is the RGBA color of the input texture. In the case of a height map you could just limit to the R value by using a vector split node, or swizzle.

[odd wraith]

so I create a triplanar from just one value the red as its black and having all the colours and stuff and I attach that to the multiplies?

[amber saffron]

In theory, yes. But I don't think it will allow you to do that ?

[odd wraith]

could we multiply the world position with everything?

[amber saffron]

Yes but ... why ?

[odd wraith]

since the swizzle things doesn't work to try to shift the height map according to the world position

[amber saffron]

Chances that it matches the other triplanar sampled textures are low

[odd wraith]

ye

so splitting it didn't work what else could I try

recreating the triplanar how you said with the texture 2d lod stuff?

[amber saffron]

yes

[odd wraith]

do you know how I could do that or should I try looking it up

[amber saffron]

You can probably find good sources by searching a bit yourself, or look at the shadergraph feature examples which contains triplanar projection subgraphs.

[odd wraith]

I'll continue looking into it tmrw

From what I'm feeling I think I'll need to make 3 uv maps for the z y and z of the texture and then map it out to thst location

[frosty linden]

How do I change the value of an enum keyword at runtime? Do I need to use DisableKeywords on all values of the enum and EnableKeywords on the value I want or do I use SetKeyword?

[hardy juniper]

This expains how they work: https://docs.unity3d.com/Packages/com.unity.shadergraph@17.3/manual/Keywords.html#enum-keywords

[frosty linden]

Thanks!

[frosty linden]

How do I properly colorize my greyscale texture ? When I use a simple multiply, black color will show details but when I use white, details disappear and some barely opaque pixel becomes more visible.

[amber saffron]

What does your greyscale texture look like ?

The usual manner to "tint" an albedo texture is indeed to multiply with a constant color.

[frosty linden]

This one. But I packed it into the blue channel and I load this packed channel from the streamingassets.

And I'm using UnityWebRequestTexture to load it.

yield return uwr.SendWebRequest();
Texture2D tex = DownloadHandlerTexture.GetContent(uwr);```

But I remember there was a linear option when creating a texture. It seems like this method of loading can't change it to linear so maybe it's the gamma affecting the result?

[hardy juniper]

it probably presumes the image is srgb (which is usually the case for most imported textures too)

[neat orchid]

Do you guys know any black magic fuckery to make particles meant for unlit shaders to work with lit shaders?

I tried several sample lit shaders and they all render my particles as solid blocks

maybe it's a transparency issue, I don't know. What should I even look into?

[grizzled bolt]

"Meant for unlit" in what sense?`
VFX graph should support lit and unlit natively
In HDRP lit shaders for Particle System are included in the importable sample

[neat orchid]

What I mean is, I bought a particle asset and its prefab uses the standard unlit particle shader

When I use any of the HDRP lit shaders, the particles break and instead display as solid of block of (correct) color

the particles use flipbooks. There is a flipbook lit shader as well but it behaves the same way

I'd assume it's something related to transparency + lighting, but I don't know what do look for

[grizzled bolt]

PS or VFX Graph?

[neat orchid]

shuriken

[young mantle]

I'am new to Unity and i have just found out about shaders this monday. I have found and tried with 5 tutorials but i still can't configure 2D shaders in Unity 6.1 are there any tutorials about how to do it?

[neat orchid]

Ok I fixed my issue. When I changed the material's shader to one of the lit ones, the albedo map got cleared. Just needed to assign it

now it works but looks kinda cursed, I will attempt to fix that with settings

[neat orchid]

Fixed some of the issues. Seems like the default hdrp particle lit shader has smoothness set to 1 for some goddamn reason and it's not an exposed property

can't imagine why

[odd wraith]

Those shadrrgraph stuff I add the addon and look at a triplanar shader graph or is that just the different nodes available in the shader graph menu

[amber saffron]

Et imports as assets in your project and you can inspect them, the shadergraph as well a the newly added nodes as subgraphs.

[odd wraith]

And then i take the subgraph for the triplanar copy it and make a new one with the texture 2d lod instead of what it uses

[frosty linden]

Hello, when I change my enum keyword at runtime, the material does update but not the value in the inspector

I use this to change the keyword at runtimemat.EnableKeyword("ENUM_VALUE");

Is there something I'm missing?

[amber saffron]

If you also want the inspector value to change, you need to use mat.SetFloat with the property reference name and value index.

[frosty linden]

Oh ok, thanks a lot

[frosty linden]

Do I need to use both EnableKeyword and SetFloat then ? Or just SetFloat is enough to enable the right keyword ?

[amber saffron]

Both.
The float is only for material editor display, while the keyword is the actual shader code change.

At runtime, you only need the keyword though.

When you are looking at the material inspector, what is happening is that when you change the value in editor, the float field changes, and then the inspector UI reflects this change to the keywords.

[frosty linden]

Ok thanks

[frosty linden]

My custom shader trying to replicate the HDRP Lit with the difference being the albedo is grayscale and packed directly in the blue channel of the mask map (I don't use the detail mask) but it seems to be struggling with the mipmap. First image is the HDRP Lit and the second one is my shader graph. The cloth gets blurry when it gets far away from the camera which should be a mipmap problem. The HDRP Lit doesn't have this issue. Is there any solution to have better mipmap with a packed texture?

[strange prairie]

If mipmapping doesn't work you're using the wrong texture sampler

SampleLevel is the function with mipmapping
https://learn.microsoft.com/en-us/windows/win32/direct3dhlsl/dx-graphics-hlsl-to-samplelevel

[frosty linden]

But there's only one sampler in my customer shader for the mask map. How can it be wrong?

[strange prairie]

Is this one of those shader graph things?

[frosty linden]

Yes

I'm using the same channels as the HDRP Lit mask map. So red is metallic, green is ao and alpha is smoothness

The only difference is the blue channel. For Lit, it's used for the detail mask but for my, I use it for greyscale albedo which I multiply by the color then plug to the color of the graph

Color, smoothness and AO seem to be working fine as you can see from the images

But it gets blurry when the texture gets further away, I think that's related to the mipmaps

But there's not option for mipmap in the shader graph so I'm not sure howto fix that

It should be the same as the lit

[strange prairie]

Yeah checks out. That sampler function calls SAMPLE_TEXTURE_2D, which takes the mipmap level into account.

Actually not entirely sure if this is correct

That's just the global mip bias.

[frosty linden]

Hm, not sure I understand your reply but is there any fix for this difference ?

The lit shader should also use the sampler function shouldn't it?

[strange prairie]

Just thinking it through

[strange prairie]

There should be a mip sampling mode in the inspector, for the Sample Texture 2D node

Should be set to "Standard"

[frosty linden]

Yes it's set to standard by default

[strange prairie]

Does your texture use anisotropic filtering? It looks more like that than a mip issue tbh.

[frosty linden]

This is my mask map texture

But both the lit and my shader graph use the same texture

And lit also use the greyscale albedo in a separate image

Which I packed into the blue channel of the mask map for my shader. It should be ignored by the lit since I don't use a detail map

[strange prairie]

Alpha is set to "none"

[frosty linden]

Yes, this is a packed texture. it has no alpha

[strange prairie]

Can you set the aniso level to the maximum value?

[frosty linden]

Ok

Hm, no luck, same result. Texture gets blurry only on my shader when far away from camera

[frosty linden]

I've tried another simpler shader graph with my mask texture and this blurry bug doesn't occur so there must be some node issue in my complex shader. I'll look into it

[frosty linden]

OK I found a solution. Changing the sampler texture mipmap to bias and setting it to -1 fixes the issue. Almost the same result as the lit hdrp. FInally/

[strange prairie]

That just turns mipmapping off

[hardy juniper]

mip maps + tri linear filtering should be making something look blurry at a distance, thats the whole point

ofc not crazy blurry but enough to look natural vs shimmer

[frosty linden]

Ah, that explain the result lol.

[frosty linden]

Ok, I didn't know, thanks

[hardy juniper]

decent article to explain a bit more: https://medium.com/@rgbguy/mipmaps-and-why-they-are-useful-6d3e33c68b16

[young mantle]

Could someone hive me helping hand?

[amber saffron]

That's very wrong.
The regular Sample operation (and "Sample Texture 2D" node) also uses mipmaps, but it determines the one that is required from the derivatives of the input UVs.

[strange prairie]

Yeah I found it afterwards after sorting through macros for a bit

It's mapped to SampleBias

[harsh marsh]

what's the equivalent to godot's MODEL_NORMAL_MATRIX in unity?

It's described in Godot's documentation as

Model/local space to world space transform for normals. This is the same as MODEL_MATRIX by default unless the object is scaled non-uniformly, in which case this is set to transpose(inverse(mat3(MODEL_MATRIX))).

[harsh marsh]

for context I'm trying to translate this from godot's glsl to urp hlsl

vec3 vec_dir_wd = MODEL_NORMAL_MATRIX * vec3(vec_dir_tg.x, 0.0, vec_dir_tg.y);

[hardy juniper]

https://docs.unity3d.com/Manual/SL-UnityShaderVariables.html many matricies are exposed to shaders

Though ObjectToClipPos() will be introduced automatically I think when using that one in a shader 🤔 (i forget)

[harsh marsh]

yes but I don't know which one I should be using

[hardy juniper]

Oh I dont actually know if there is easy conversion to/from tangent space

[regal stag]

Sounds like it might be unity_ObjectToWorld (if scaled uniformly) or transpose(unity_WorldToObject)
So should also be equivalent to TransformObjectToWorldNormal(v) function (from SpaceTransforms.hlsl in srp core shaderlibrary)

[tacit parcel]

this might be not shader specific but I'll ask this here anyway

I have a mesh with two materials, I want to overlay another material (parryIndicator) over those material by adding the overlay material into the mesh renderer
But somehow it only overlaid on the last material (the straw cape/Mino), is there a way to make it overlaid on the whole mesh instead?

[ebon basin]

So the problem here is you've a mesh and a submesh, and you want the last material (which is an overlay) to apply to both but it's only being applied to the previous submesh? I think I may have had this problem before but I don't think using the editor will work here to specify that

I usually just do another mesh rendering if I want to do some overlay

[tacit parcel]

Ah right, I forgot that its treated as submesh, and the additional shader only applies to the last submesh 🤦‍♂️
Seems like the "fix" is to not having submesh? either join everything as a single mesh or make it as another mesh?

[ebon basin]

Probably yeah

[tacit parcel]

Cool thanks

[odd wraith]

what's the difference between the pink and blue node connectors

[odd wraith]

I'm trying to first make a normal shader with a height map and then going to triplanar. But the heigh map looks a bit choppy and not smooth. What can I change to fix it?

[neat orchid]

Are texture 2d arrays always more performant than sample texture 2d if you're blending different textures on the same material via vertex color?

[pseudo escarp]

Yes that way you only have one texture loaded in the gpu memory instead of two separate textures loaded. Both ways are still two samples

[neat orchid]

Yea but what do you mean by both are still two samples? You mean to say that just literally?

Cause even if you have like 16 textures, it's gonna perform fine vs a splat map or even vs vertex colors with less textures, as I understand it

[supple sentinel]

i followed along a tutorial, but is there anyway to make this toon shading colored? i think shadows being grey tends to look kinda ugly (second pic is whats inside the node group highlighted)

i keep trying to do something like this, but it changes the body instead of the shadow

[regal stag]

If you want to tint the whole thing, add the ambient to the Smoothstep output, then Multiply by the Color. Or replace the Ambient Strength with an Ambient Color.
If you want exact control over the colours of the "shadowed"/lit sides, put the Smoothstep output into a Lerp node with A & B set to Color nodes.

[supple sentinel]

ok let me try to understand this and report back :D

thank you so much 🙏

[cerulean nexus]

what am i not understanding about Sorting Priority? I have 2 gameobjects, the first has a sorting priority of 0 and the second has a sorting priority of 50. To my understanding, the second object should always render after the first, but it still gets blocked for some reason. is there anything that im missing?

[lucid perch]

hey i made this toon shader and im trying to add normalmap support to it. can somebody explain why i cant drag it into the normal output?

idk if its important but its in urp and unity 6000.0.41f1

[regal stag]

Afaik Sorting Priority is an offset to the Render Queue behind the scenes, which is determined by other settings. (Opaque has a queue of 2000, Opaque & Alpha Clipping is 2450, and Transparent is 3000). The priority would only affect the order objects render in if both materials have the same Surface Type & Alpha Clipping.

If both are opaque, the sorting priority still wouldn't force the second object to render over the second though - as opaque objects write to (and test against) the depth buffer. You'd instead need to override the ztesting mode using the RenderObjects feature or a custom shader. (Probably using ZTest Always, but then faces in the mesh also won't know what order to render in unless you do 2 passes like this discussions post)

[fast igloo]

shader I made completely in shader graph, anything I should add lighting-wise?

[regal stag]

The normal map would need to override the Normal Vector node probably used inside the CalculateLights subgraph. Can add an input to the subgraph to handle that. (Good place to use a Branch On Input Connection too, but optional)

The normal sample also doesn't look correct. If it's a blue/purple-ish texture Tangent space and a Transform node to convert from Tangent to World for the lighting calculations. Also no need for the Normal Unpack node - the Normal mode on the sample handles that

[lucid perch]

i tried it like this now but i prolly did something wrong as it still doesnt look correct on the material

[regal stag]

Use Absolute World space on the Transform node instead of Object
Make sure you assign a valid normal map to the property & connect in main graph

[lucid perch]

this is what my normalmap looks like and what my object looks like with my shader (top) and the default lit (bottom) i see progress but its still not working right

also the colors i set are different but i think thats not the problem

[drowsy marsh]

any recs for an already made reveal shader?

willing to purchase one

[sand ingot]

Im using unity 6 urp, custom shaders are working fine in play mode but in build they are pink.

no shader errors at all and i've tried disabling all the stripping options for shader varients

I've also created a new shader variant collection and added it to this list of preloaded shaders and added the specific shader to the 'always include shader' section in graphics settings

im sorta losing my mind here what haven't i tried yet

[kind juniper]

Make sure you're using the same quality settings in the target platform build. Or make sure that the correct settings use the same render pipeline.

[sand ingot]

Yeah that all seems in check

i've tried it in new unity projects as well and builds are still breaking

i've also tried using different unity versions

[kind juniper]

Did you try looking at the player logs?

Or attaching a frame debugger to the build.

[sand ingot]

I looked at the player logs

didn't see much but i'm not familiar with the specific logs its putting out

chatgpt says its fine but 🤷‍♂️

[kind juniper]

Anything about shaders?

[sand ingot]

haven't tried frame debugging

[sand ingot]

nothing unusual as far as i could tell

[kind juniper]

Try the frame debugger then. It might reveal more details.

[sand ingot]

will do

[hardy juniper]

Check the build logs to see what shaders are included (it should mention variants and the reductions from stripping)
If ones you need end up at 0 then it could be the cause.

addressables had a bug a while ago that would cause 100% stripping for shaders used

[sand ingot]

what am i looking for exactly?

I'm now getting an issue with the standard urp/Lit shader but that seems unrelated?

[hardy juniper]

there should be a stage where it lists all shaders and it processes the variants and reduces the variants built

[sand ingot]

ok i don't see the custom shaders being included

[hardy juniper]

you should enable keeping the urp debugging shaders and then enable urp debugging in a build: https://docs.unity3d.com/Packages/com.unity.render-pipelines.universal@15.0/manual/features/rendering-debugger.html

[hardy juniper]

Look for things like this:

    Full variant space:         301989888
    After settings filtering:   24576
    After built-in stripping:   48
    After scriptable stripping: 16
    Processed in 0.00 seconds
    starting compilation...
    finished in 0.62 seconds. Local cache hits 0 (0.00s CPU time), remote cache hits 0 (0.00s CPU time), compiled 16 variants (4.34s CPU time), skipped 0 variants
    Prepared data for serialisation in 0.00s```

here it only keeps 16 variants. If it goes to 0 but you know its used then thats a bad sign

[sand ingot]

I'm not getting those debugs, maybe i need to enable something?

I see a lot of

Uploaded shader variant to the GPU driver: Hidden/Universal Render Pipeline/LutBuilderLdr (instance 0x128), pass: LutBuilderLdr, stage: vertex, keywords <no keywords>, time: 0.077 ms
Uploaded shader variant to the GPU driver: Hidden/Universal Render Pipeline/LutBuilderLdr (instance 0x128), pass: LutBuilderLdr, stage: pixel, keywords <no keywords>, time: 0.089 ms

Looking into frame debugging now

[hardy juniper]

its in the editor log/std output when building

[sand ingot]

oh im in the wrong place

[hardy juniper]

you want to basically check what happened with shader compilation for your builds

[sand ingot]

yeah im in player logs

yes ok it is getting stripped

Compiling shader "Custom/Portal" pass "Unlit" (vp)
    Full variant space:         1
    After settings filtering:   1
    After built-in stripping:   1
    After scriptable stripping: 0
    Processed in 0.00 seconds
    Prepared data for serialisation in 0.00s

how do I exclude it?

[hardy juniper]

it must think no variant is used so its fully stripped

[sand ingot]

can i whitelist it somewhere?

[hardy juniper]

is the shader used by a material that is in the build?

[sand ingot]

yes

i've tried setting up a dummy scene with just the shader and a camera

[hardy juniper]

Resources?

[sand ingot]

doesnt workj

I could try turning off all stripping but that took like an hour to build last time

[hardy juniper]

yea not a solution as builds will take a stupid amount of time. Is it shader graph or .shader file?

[sand ingot]

.shader

oh god well

ive changed absolutely nothing and now it works

thanks for your help

i might be back if it decides to stop working

[heavy plover]

What type of shader do I need to use if I want a procedural material for a UI image?

It doesn't seem to work using the same one as the sprites

At least not transparency??

Ok, wtf, why does it show tranparency alright on the scene window but in game decides not to

Can be something in the camera?

[regal stag]

If you're using shader graphs, you need to use the Canvas Graph type in 2023.3 / Unity 6. Older versions didn't have proper UI support - though it would somewhat work if using a Screenspace-Camera canvas (not Screenspace-Overlay)

[minor remnant]

how can i rotate a float4x4 matrix around a vector by x degrees?

[olive igloo]

Hi, is there a way for a material with emission to be affected by lighting? like if theres a light it can have shadow and if its dim the color will slightly darken? i really like the color of the mat with the emission and hdr

[dim yoke]

I'm not sure what you mean by rotating a matrix but I assume you just mean multiplying it by the rotation matrix which would be https://en.wikipedia.org/wiki/Rotation_matrix#Rotation_matrix_from_axis_and_angle

[minor remnant]

that is indeed what I mean

thank you

[dim yoke]

If you can do it on C# side, the matrix would be something along the lines of Matrix4x4.Rotate(Quaternion.AngleAxis(...

[minor remnant]

unfortunately even though I know its more expensive my needs kinda require it to be done on GPU

[dim yoke]

Alright. I'm just wondering whether there is an easier and less boiler plaity way to do it in shader code (using some built in functions) which there likely is but it also depends on the shader language

[wise igloo]

I have been trying to recreate this shader for the last hour or so but im fail to recreate the adding color with step:https://www.youtube.com/shorts/nKztilUwAG4. If someone could assist me i would be really gratefull the image shows my current progress.

[amber saffron]

It's probably because your are using step after multiplying with the WaveStrengh :
You are stepping an already scaled value, if you use the output of the Sine node instead, you know that the step input value is in the [-1;1] range.

[wise igloo]

Ohhh makes sense i will try it out later and will give feedback if it worked out. But ty ❤️

[strange prairie]

I'm working on a custom terrain shader - trying to hide holes at a certain distance and for some reason that if test is doing nothing:

#ifdef _ALPHATEST_ON
if(posInput.positionWS.z < 10)
{
        float hole = SAMPLE_TEXTURE2D(_TerrainHolesTexture, sampler_TerrainHolesTexture, input.texCoord0.xy).r;
        GENERIC_ALPHA_TEST(hole, 0.5);
}
#endif

This is a custom pass that takes a PositionInputs struct.

I tried to debug using:

    terrainLitSurfaceData.albedo.r = posInput.positionWS.z / 300;

And I'm seeing expected results there - fading to red approximately 300 meters from the camera.

Alternatively, going branchless, still nothing:

float hole = SAMPLE_TEXTURE2D(_TerrainHolesTexture, sampler_TerrainHolesTexture, input.texCoord0.xy).r;
hole = lerp(hole, 1.0f, posInput.positionWS.z);
GENERIC_ALPHA_TEST(hole, 0.5);

posInput.positionWS.z behaves like it's returning 0. Unless I plug it into the albedo, where it returns the expected value. In the same function.

[amber saffron]

IIRC, terrain holes are "real" holes (no triangles), not alpha test

[strange prairie]

No, it works fine if I set hole to 1 manually

[amber saffron]

Oh, ok, my bad.

At first I'd say to instead use length(posInput.positionWS) instead (else you are purely testing on the z positive value), but it's still strange that it behaves differently when plugged in albedo 🤔

[strange prairie]

From what I can tell the clipping happens during the depth pass, while albedo is done during the Gbuffer pass

This does raise the question why they run this entire expensive pixel shader for the depth pass

Solved using input.positionSS.w, which is filled during the depth pass.

[steel notch]

I am making a Chromatic Aberration subgraph. I am creating it by sampling the same texture 3 times at slightly different UV offsets, and then combining the R, G and B from the different textures samples. How do I combine the alpha? Here is the current graph.

[tacit parcel]

isnt it usually used in post process where alpha doesnt matter?

[amber saffron]

If you really need alpha, you could take the average, or maybe use the RGB to luminance weight for accumulating it 🤷‍♂️

[steel notch]

Add them all together, then divide by 3?

😛

[amber saffron]

Yes

Or something using these constants :
alpha = 0.2126 * RAlpha + 0.7152 * GAlpha + 0.0722 * BAlpha

But like rakiat mentioned, usually chroma aberation is a post process where you don't care about alpha.

[slender ore]

I tried using real time raytracing in my HDRP project and my shaders stopped compilling and I got error message Shader error in 'Shader Graphs/BarkShaderMoss': Opcode DerivCoarseY not valid in shader model lib_6_3(closesthit).. I have disabled the raytracing but this error remains, any idea on potentiall fix?

[static star]

Trying to create a color replace shader (so I can recolor outfits of players for example).... but this doesn't seem to work.

Tried following a simple tutorial but am I doing something wrong? Cause it works in the tutorial
https://www.youtube.com/watch?v=XW2qW1sDj_A

[static star]

ok so I seemed to fix it when I changed the Range to "0.1" but why is this the case?

[amber saffron]

The error is because somewhere in your graph derivatives functions (DDX, DDY) are used.
As for the remaining error, sometimes there errors still display in the import inspector or console for no reason, did you try to reimport the shadergraph asset ?

[slender ore]

yes. I kinda figured out what happened. I turned out that it wasn't every shader that was giving me this error but rather a signle shader that was giving me 8 similar errors. So I removed that one and the rest works

[amber saffron]

The range value is the error threshold for the color matching. When it was set to 0 it required the exact same color between the texture and the "color to replace" value to work, so I suspect that it was not a perfect match before, maybe due to compression or float approximation.

[strange prairie]

Re-generating the HLSL from the shader graph should work

Should also make ray tracing work

[slender ore]

Will try that, thanks

[static star]

one more thing.... since this is going to be a multiplayer game, I need a way to make this work for other players. Atm if I just do this all players would have the same material values and look the same... so what should I do I guess?

a friend of mine said something about "material variants" or something? But doesn't know a specific term for this so its hard for me to google or lookup what exactly I need to do

[amber saffron]

From script you can change the colors using Material.SetColor .
And by accessing the material from the mesh with MeshRenderer.material a copy will automatically be made to avoid modifying the original material asset.
At the end you will have X players with X different materials and colors using the same shader.

[static star]

so something like Material.SetColor.SwitchToThisColor2 = Red/ColorPlayerSets; or something?

[amber saffron]

You might want to look at the scripting API (or playmaker since I see you're using it).
The correct syntax for example is : material.SetColor("ColorReferenceName", Color.red);

[static star]

tried coding it but haven't really been successful so far. Any idea on what im doing wrong here?

cause here... I am trying to make it so I put it on a parent of the character body, then apply the color changes to everything that is a childed object of that parent

Note that like all arrays returned by Unity, this returns a copy of materials array. If you want to change some materials in it, get the value, change an entry and set materials back.

foreach (MeshRenderer renderer in GetComponentsInChildren<MeshRenderer>())

[static star]

still not working, am I just not connecting to the renderer still I guess?

Because I if I edit the Material variables from the Shader Graph directly it works... so its a connection issue to the renderer right?

[amber saffron]

From what I see, it should work 🤔
Any errors in the console ? Did you try loging things (like renderer names) to check that it passes on the proper objects ?

[static star]

no errors, but I can try logging

[static star]

I was using MeshRenderer in script.... but my character used SkinnedMeshRenderer 😐

[amber saffron]

Makes sense.

[stable bolt]

Hi there, I retrieved an asset using Command Buffer in URP, those call don't batch with the SRP batcher, I'm trying to squeez every last drop for mobile and I was wondering if there were an extensive guide somewhere to help me port the Render Feature to use the BatchRenderGroup API ?

[static star]

but ty for helping me.... I finally got that figured out and I think I can probably figure out how to replace meshes with the skinned mesh renderer

[stable bolt]

The documentation seems nice but as I don't know the Command Buffer API neither I'm a bit at a loss, or better, I'd like to know if I can 1:1 the thing or if Command Buffer and BatchRenderGroup are totally unrelated ?

[low lichen]

CommandBuffer is for executing many different commands on the GPU. BatchRendererGroup is an API solely for generating draw commands. In what way is your asset using CommandBuffer?

[stable bolt]

CommandBuffer is for executing many

Hello, I am looking for guidance or resources on how to add height map functionality or displacement to the unity toon shader. Its based on DX11 tess but its Tess CG file is missing any references to height.

[stray gulch]

is there any reason transparency wouldnt be working with urp? trying to convert my shaders to urp but it just totally disregards my transparent pass

left: built-in
right: urp

didn't even touch the shader code and it already doesnt work

[grizzled bolt]

By that you mean you're using the shader code from birp version, or using urp defaults?
Is it a custom transparency pass?

[amber saffron]

There is a basic displacement tessellation shader example in the doc.

[knotty surge]

anybody know if there's a (preferably simple) way to make an arbitrary amount of semi-transparent sprites, positioned, say, like this, have the same brightness throughout instead of blending with eachother

[strange prairie]

Stencils would be one solution:
https://docs.unity3d.com/6000.0/Documentation/Manual/SL-Stencil.html

That way one is discarded if they overlap

[knotty surge]

i see

[strange prairie]

Out of curiosity, do you know how that could be done in the HDRP? What pass should a tessellation program run in?

[amber saffron]

A lot of them.
Basically, take a generated shader from shadergraph with tessellation, and look at all the passes that declare a tessellation stage.

You'll need it for gbuffer, depth, shadow, forward ....

[strange prairie]

Right, so all of them except probably ray tracing

I suppose shadow could live without too

[amber saffron]

Really depends on what your are doing with the tessellation, else the difference between the shadowmap and view geometry could easilly lead to shadow artifacts

[strange prairie]

Yeah will have to experiment there

[hushed silo]

I am doing SDF lighting/shadows/ao using primitive SDFs. I am coming across these artifacts sometimes, what are they? like, what should i search for to try and figure it out

[amber saffron]

It's quite hard to understand what is the artifact here. But since it looks like it's some "steps", could it be that you need to increase the number of raymarched steps to increase precision ?

[strange prairie]

That or some kind of anti aliasing

Or blur

[hushed silo]

this was my first thought, though changing the number of steps and minmax distances doesn't seem to alter it

[golden raven]

how can I make my outline shader thicker? to match my character's artstyle

this is my current setup atm

when i try increasing thickness it just renders incorrectely because its not filling the space between the object and the outline (and me trying to explain the issue just rubberducked it lmao)

[hushed silo]

https://www.youtube.com/watch?v=Bm6Bmcjd1Mw

[golden raven]

thats the exact guide I used

but again, for him it looks good, not for me

[hushed silo]

sorry didn't mean it as a lmgtfy

[golden raven]

all good

[hushed silo]

but it is the BEST so you should be good 😛

[golden raven]

im on urp if that helps

[golden raven]

the closest I found that matched my hb's artstyle was maybe cell shading, but I don't want cell shading because its a cartoon-like game, not an anime

[hushed silo]

i'd assume the proper proper way would have something to do with stencil buffer etc but i dunno

https://www.reddit.com/r/opengl/comments/11mb9lm/screenspace_outline_using_stencilbuffer/

[golden raven]

this tutorial is for smooth shaded objects only damn

my objects are definitely not smooth shaded, its low poly

[hushed silo]

isn't it just a screenspace outline effect applied over whatever?

no sure that shading would have any impact

[golden raven]

wym?

[hushed silo]

that the outline is its own shader

[golden raven]

oh no, its a shader graph

[grizzled bolt]

The shader has an Outline Thickness property
That's not doing what it's supposed to?

[golden raven]

well yes but when I increase the thickness, it just floats in the air and the space between the object and the outline is transparent

let me show a pic

thickness: 0.01235

thickness = .1

you can see it better on the couch down there

and also its not adding an outline to every part regardless of direction, I believe that has to do with normals?

[grizzled bolt]

In couch's case I believe the outline is going inside the wall because it's above the couch's surface but the couch is right up against the wall
And floor for the radiatior

[golden raven]

i forgot why it was on back and not both

[golden raven]

the sofa is clipping a bit through the wall but its not an issue

[grizzled bolt]

It's an issue for the outline

[golden raven]

it wasnt clipping through the wall, so idk then

it should just be black between the outline and the actual object

[grizzled bolt]

It has to be far enough away so the outline's added width is not touching the wall

Move the sofa up and away from the surfaces until the outline appears

Anyway those are fundamental limitations of this particular outline method
You can tweak the properties and the object positions to make it look potentially adequate from the camera's perspective
If the player can't move the camera right up where the errors appear, the errors won't matter

Otherwise you'll have to find a different method
Each has drawbacks
https://ameye.dev/notes/rendering-outlines/

[golden raven]

is there anyway to avoid that? because I really have some space constraints world wise

[grizzled bolt]

The normal offset method is similar, but it fixes the outline becoming proportonally detached
But it has the same clipping issues and additionally it'd have a splitting issue with any flat shaded geometry edges

[golden raven]

i dont want anything floating around

[grizzled bolt]

Currently your outline is created by duplicating the mesh and expanding the duplicate
You can shrink the mesh by the same amount so the space doesn't change
If the outline is resting on the floor against the wall without clipping, it won't really be "floating"
Only the object inside the outline is floating but to an outside viewer the outline is a part of the object so there's no floating

[golden raven]

how do I even shrink the mesh in unity?

because scaling it doesnt change anything

[grizzled bolt]

The same way you shrink anything else
What precisely are you trying to scale

[golden raven]

the gameobject itself

[strange prairie]

The jump-flood algorithm described here seems pretty good https://bgolus.medium.com/the-quest-for-very-wide-outlines-ba82ed442cd9

[grizzled bolt]

All outline methods are pretty good but all of them have drawbacks and require attention when working around the drawbacks

[golden raven]

so i basically render the object twice but one of them serves as the outline?

[strange prairie]

No, that's the method you're using

This is a full screen effect based on signed distance fields

[ebon basin]

Unfortunate part of flat shading is your outlines will never look good

as far as inverted hull goes

[golden raven]

i just need them to look like their just as thick as the main character's drawn outline

[ebon basin]

The real way to fix this if you do want to silhouette inverted hull is make a secondary mesh that you do smooth shade / bevel down

[grizzled bolt]

If they're static and you're trying to scale them at runtime that's one reason why it might not work

I assume you have two separate objects for the mesh and its outline, so you'd be scaling them together or scaling a parent empty

[golden raven]

they are static

[ebon basin]

the silhouette is a good idea though and worth a try, similar to the stencil shader idea above

what you can do too if just apply another material to the mesh renderer and make it black

that scales it but a few units

[grizzled bolt]

Smooth shading the mesh for specific purposes like this is very helpful
Why isn't it an option in the mesh renderer or even the mesh import settings

[dim yoke]

I guess one way would be to store the smooth shaded normals on some secondary UV channels. One could maybe create some sort of asset importer/editor script that does that automatically for certain models. Could also work the other way around by keeping only a smooth shaded mesh and drawing it as flat shaded via normal maps or partial derivative normal reconstruction but those may not be visually (nor technically) the best solution.

[warm pulsar]

is there any documentation for how ScenePickingPass and SceneSelectionPass work? I'm trying to make sense of them for a custom terrain shader

https://github.com/TwoTailsGames/Unity-Built-in-Shaders/blob/master/DefaultResourcesExtra/Particle Standard Unlit.shader

So far, I have the following understanding:

• ScenePickingPass is used to click on things. If you discard a pixel, it can't be clicked on. If you return a bogus ObjectID value, the pixel can't be clicked on.
• SceneSelectionPass is used to draw the outline. You return a 4-component vector. If the second component is negative, the outline is faint.

I can manipulate these on the Standard Unlit particle shader

and I get results that (sort of) make sense

I haven't gotten either to work on my terrain shader yet

[golden raven]

https://www.youtube.com/shorts/FyEiPibJuRU

is this a good method or nah?

performance wise will it take a hit?

[warm pulsar]

annoyingly, all of the built-in shaders reference this pass:

Hidden/Nature/Terrain/Utilities/PICKING

but I can't find a definition for it anywhere

ah, right, i forgot that the pass name would just be "Picking"

the rest is the name of the shader

oh lmao, I can just do

UsePass "Hidden/Nature/Terrain/Utilities/PICKING"
UsePass "Hidden/Nature/Terrain/Utilities/SELECTION"

since I'm not doing anything different to the shape of the terrain

i'll have to figure out why my own passes were not working

[stray gulch]

custom transparency pass, but I figured it out

initially every section was given the alphatest queue

but since some textures don't have any alpha that needs blending, I can just check the texture type and make sure the alpha multiplier is 1 or 0, then set it to geometry queue

and everything works fine and I can remove the dupe transparency pass

[gloomy fractal]

how can i achive sunlight shining through my grass?

[grizzled bolt]

Can you specify what kind of shining through
To disable shadow so sunlight can reach the ground through the grass?
For the sides of the grass facing away from sunlight to not be in darkness?
Or something else

[gloomy fractal]

this effect

i also looked for subsurface scatering

really difficult to find any helpful infos

by the way the image i posted is using urp

[grizzled bolt]

Shader Graph's importable Production Ready Shaders sample has an example implementation of that

For both grass and shrubs

[gloomy fractal]

wow that sounds really helpfull. i will check that out

thank you very much

[grizzled bolt]

Samples for pretty much all packages that have them are great, some I'd even call essential for starting out

[gloomy fractal]

yeah looks really interesting

[teal lynx]

that is very pretty, have fun

[stray gulch]

super tired of trying to figure this out, does anyone have any resources for a pixel-perfect outline system for urp

[grizzled bolt]

That sounds like a tough one
I'd imagine the most practical way to do it would be to fake it with secondary textures where the outlines are pre-drawn (or generated)
If the per-sprite limitation of that is too limiting I think you'd be looking at jump flood algorithms drawn as a full screen effect

[atomic glade]

I'm trying to make a shader that shows intersections with terrain, and I'm trying to follow this guide to do it: https://www.youtube.com/watch?v=Uyw5yBFEoXo

I'm at about 4:00 into the video. The cube is apparently supposed to be looking like the first image, but what I'm getting is the second image. I'm on URP, and I followed the instructions at the start for making sure the depth texture is checked in the URP asset. There isn't a point in the video where he shows the entire graph to compare screenshots, but starting at about 3:45 you should see everything and compare it to mine in the third screenshot. What have I missed, why is mine so... incorrect?

[stray gulch]

nah not sprites though, 3d scene

trying to replicate the edge marking effect on the Pokemon nds games

[stray gulch]

preferably a stencil solution too, so I can just mark which ones I want to be outlined

[kind juniper]

Hmmm... Hard to say. What I can suggest is try plugging the screen position.a into the color and the same thing with scene depth. And see if they seem to be returning the values that you might expect

[atomic glade]

I did both of those, and I just get a solid color, no changes as I move the object around.

[kind juniper]

I see. I'd try looking at the frame debugger then. Perhaps the depth texture that is bound to the draw call is incorrect. Is that an opaque material btw? Where exactly is it rendered in the render queue?

[atomic glade]

I don't actually know what the frame debugger is. I'll need to find out. The material is transparent. I haven't changed anything in the render queue from what I know of

[kind juniper]

I'd attribute the screen position a being a solid color to there being a very small spread that is not noticable to the human eye.

[kind juniper]

Try with opaque and see if there's any difference for scene depth being plugged in the color output.

But yeah, the frame debugger should make it more clear.

[atomic glade]

Just to be sure, this stuff should be working in scene view, right?

[kind juniper]

Nnn... Hard to say. For safe measure better check in game tab

[atomic glade]

Okay, actually, I found out that Screen Position does work in transparent, I was just also piping it to alpha and it was showing me pure white. I get color changes as I move around the cube with Screen Position set as color

Scene Depth is still solid white, opaque or transparent

[kind juniper]

Yeah, so frame debugger it is

[atomic glade]

Actaully, Scene Depth does darken it when I get like, right up into it. It starts to dim literally moments before it's too close to render

[kind juniper]

Aha. Try changing the node to linear

Sampling mode of the depth I mean

Or raw

[atomic glade]

It is now solid black no matter where I go

Same with Raw

[kind juniper]

Hmm... I'd try these mods with he actual final shader and see if it works perhaps.

It could look like solid black to you simply because the range is very small.
Maybe try zooming way out back, such that it aligns with the furthest thing in the scene.

[atomic glade]

Okay, so, the cube was very small and the scene is quite large, so I blew up the cube to 1000x1000 to see if I could notice anything at a distance. On "Eye" mode, it rapidly cycles through black to white as I scroll in scene view, but not if I hold down the right mouse button and move the camera in or out...

I really don't understand what these nodes are even doing, I can't explain why it's doing any of this

This is with the shader as pictured in the original question, the "partially complete" shader

I'm gonna have to come back to this tomorrow, but if anyone has any ideas ideas in the meantime for me to try when I get back, I'll give them a shot

[regal stag]

You have alpha values outside the 0-1 range which'll lead to strange blending - add a Saturate node before connecting to the master stack

[kind juniper]

It shouldn't cycle.
In the simplest form, depth should go from 0 right in front of the camera to 1 at the very furthest point from it(around where the camera far clip distance is).

Now, it can be linear or non linear(such that differences closer to camera are more impactful then those further away).

The value ranges could also be different. Some platforms/apis have it in reverse, where 1 is closest and 0 is furthest. Sometimes it's also non normalized or an integer, so the farthest value is something like 60k, depending on the depth format.

[atomic glade]

Still doesn't do anything remotely close to the video. It's just no longer doing that weird cycling when I zoom

[hardy juniper]

From what i can tell this shader uses the difference in the fragment depth to the depth in the depth buffer to change alpha?

[atomic glade]

Seems to be. The video does a good job of explaining what these nodes mean but they don't line up at all with the results in getting.

I'm just trying to get the shape of this mesh to glow when it's intersecting the terrain. I know enough shader graph to get it to look like something if I can just replicate that alpha falloff from the intersect point effect

[hardy juniper]

So the cube is transparent in their video and the floor is opaque? Import to know for what is writing depth

[atomic glade]

They don't show the floor but that sounds correct, that's what I have

I have this basic full screen post-processing shader. Right now it's creating a sphere centered at a position in screen space, but how do I turn this position into world space?
https://paste.mod.gg/xytgeajlngkm/0

I think I'm supposed to use unity_CameraToWorld but I'm not sure how.

[kind juniper]

I'd check the frame debugger after all. You can see what the depth texture contains when the draw call executes. It could be that the object is already rendered to the depth buffer at that point, causing there to not be any difference between the 2 nodes.

This is likely more than just a shader issue - it has to do with when and what the render pipeline is rendering to the depth buffer/texture.

[kind juniper]

You'll need to sample the scene depth at that pixel and use some matrix transformations to calculate the world position.

[teal lynx]

oh god sounds complicated

thanks for the info

[brazen nimbus]

Hello there ! What would be the best way to create a mask in black and white depending on the layer of what my camera sees ?
I'm trying to work on a post process effect but I don't want it to affect my characters. I'm using a fullscreen shader graph that I plugged into my Universal render data. My guess is to modify the render pipeline so I can create a render texture without my character which will be full black, another one with only the characters which will be full white and combine both but I'm not quite sure that's a good (and not even the best way !).
If you have any ideas, I'll be glad to know ! Thanks in advance ! 🌺

Lovely, thanks ! :)

[golden raven]

anyone has an idea on how to make the glass not render the wall that it's going through?

im making a shopfront simulator

[strange prairie]

Cut out part of the wall mesh

Like, sure you could do it with shaders but that's kinda weird lol

[golden raven]

thing is, the shopfront is generated through an input

you basically set in your size (in meters) and it'll just show up on your scene once you're done

im trying to make a program to pitch in my idea to the company im interning at right now

[strange prairie]

You can use stencil shaders

[golden raven]

i need to look up a tutorial on that

but the principle would to just have the glass material ignore the wall material no?

[strange prairie]

Wall wouldn't render if glass was in front of it

[golden raven]

ohh true

[golden raven]

stencil buffer?

[strange prairie]

Yes

It's in the documentation. Pretty simple.

[neat orchid]

Does anybody know how to create a flipbook frame interpolation shader for lit particles

[timid fossil]

If you want to use Shader Graph, you can find an example in the HDRP particle sample:

[golden raven]

it looks pretty complicated to me 😭

[strange prairie]

You write a value to the pixel, the other shader reads this and decides to discard if it's that value

[golden raven]

oh

[golden raven]

but im just confused on how I'd apply that onto here

all pixels behind the glass should be set to that value that gets discarded

but how?

[strange prairie]

Let's take the example from the docs. This would be the glass

Stencil
 {
   Ref 2 // The value to set the stencil to
   Comp Always // Do this always
   Pass Replace // Replace the value
 }  

and this would be the wall:

Stencil
 {
   Ref 2 // The value to compare to
   Comp Less // We only render if the stencil buffer is less than Ref
 }  

So if the glass is in front of the wall, it's already been rendered when the wall renders and the stencil buffer will be 2.

[golden raven]

so I can make two shaders and slap the code in?

[strange prairie]

Yeah pretty much.

[neat orchid]

Wait, that's the lit flipbook shader?

[golden raven]

next time I'll sleep for more than 6 hours before working on unity 😭

shits tiring but fun

so what am I supposed to do? I applied the shaders onto the materials

[golden raven]

i just copied these into each's shader and yeah

[vocal axle]

im trying to make a stereogram shader, but its not working and i cant for the life of me figure it out since there hasnt been good info about them since there hasnt been info good about them for decades probably.

probably some issue with not being able to properly duplicate the displacement to the right or left? ugh.

[strange prairie]

Is there anything else in the shader? 😄

It still needs to render

Magenta means you have errors anyway, if you select the shader in project view it'll show you the errors

[golden raven]

yeah, i used the standard surface shader

not sure where to look, on the inspector its clean, the console has unrelated warnings, but no errors

[golden raven]

can anyone help me with the pink walls not being rendered in my shader please😭

he left me on read so I'm unsure as what to do or search even

[golden raven]

im using the standard surface shader as a template then adding the stencil lines for each of the materials but it is not working

[amber saffron]

Are you using the built-in render pipeline or URP ?

[golden raven]

URP

[amber saffron]

That's the issue, Standard Surface Shader doesn't work with URP.

[golden raven]

well which one of these works?

[amber saffron]

Using stencil is URP is a bit different an requires the use of RendererFeatures : https://www.youtube.com/watch?app=desktop&v=y-SEiDTbszk

[golden raven]

man no offense I'm really not trying to look up every tutorial ever because they are either awfully vague or keep explaining what it is instead of actually showing what to do

[golden raven]

thats kinda way I came here, the only reason why im even on the right track is because of them telling me what I should do

[golden raven]

I know I need to be patient but I really want to get this problem out of the way it's been taking me the whole day 😭

[amber saffron]

I've scrubbed through the tutorial, and it is showing what to do to use stencil in URP, with 3 different outcomes.

[golden raven]

alright then

imma come back if i dont understand the video

[ebon basin]

If you dont understand the video then start researching how the stencil buffer works because that's the keyword here

Not unique to unity

[golden raven]

instead of the ground, im making it onto a wall but my wall is still not rendering

the left is his video, the right is my settings

my glass material itself is rendering correctly, its only my wall material that isnt

i tried reverting it and still kept not being rendered (the wall)

[atomic glade]

I'm back and I'm working on finding out what's wrong with the renderer here. I've opened and attached the frame debugger and it gives me no information. Every step looks exactly like this. I made a fresh new scene that just has a plane and a cylinder with this material on it. What kind of information am I supposed to glean from this debugger? Nothing looks like the material I've set and I can't get detailed info on any of these steps.

[atomic glade]

I am wondering if this has something to do with it. I do have scriptable render passes for rendering outlines, and I do not know enough of this system to convert them. Changing this compatibility setting just spams that I have a pass that doesn't implement some graph function and I have no idea what that does or how to convert it
