archived-shaders

[neat hamlet]

nope

[subtle thicket]

Someone mentioned using a render texture to broadcast a camera looking at a sprite onto the ui... but that feels pretty janky

Is a code shader harder to work with than shadergraph?

[neat hamlet]

ehh, I find it much easier but I don't like graphs

how complicated is your graph

[subtle thicket]

Like ten nodes. But I'll need to add more to it later

Everything else including animation is in code form already, so I guess why not add shaders to the list

[neat hamlet]

URP still uses the built-in shaders for UI, so you can grab those

[subtle thicket]

What do you mean?

[neat hamlet]

https://github.com/TwoTailsGames/Unity-Built-in-Shaders/blob/master/DefaultResourcesExtra/UI/UI-Default.shader

[subtle thicket]

(I only learned about shaders like a week ago)

[neat hamlet]

thats what URP uses for UI

now, you see the properties with stencil, and the stencil block? those, and the ZTest mode make it work in UI

[subtle thicket]

hmm geez, that's some weird stuff going on

[neat hamlet]

Stencil block is for UI masks, Ztest is to make it render in game view

so if you don't need the UI masking, you can just use the ztest mode

maybe you can generate the code from the shader graph, and just add the ztest

[subtle thicket]

What would UI masking do?

[neat hamlet]

the UI mask component, use one image to keep another image in its alpha

[subtle thicket]

Geez, I'm looking at his built-in shader code and not understanding any of it 😅

[neat hamlet]

oh nearly all of it is boiler plate

[subtle thicket]

Well my sprites do use a secondary texture to get the colored glow effect. But I don't know if that counts as masking

[neat hamlet]

no

[subtle thicket]

Okay good! So how do you 'generate the code' from the shader graph?

Is there an automatic way or no

[neat hamlet]

I think theres a button on the graph somewhere

[subtle thicket]

I guess it's this one. It pulled up a 1300 line class 😅

[neat hamlet]

yeah

graphs arent very efficient :V

[subtle thicket]

So I guess I can't just set the ztest in here and call it a day?

[neat hamlet]

well hopefully all of the unused stuff gets pulled out at some point, but yeah theyre not human friendly

should be able to

[neat hamlet]

yeah, so replace the ZTest LEqual

ZTest [unity_GUIZTestMode]

with that

also save it in another file so it doesnt get overwritten next time you hit generate code

and change the name on top to you can find it when you switch the material

[subtle thicket]

hm, looks like there are one or two errors

let's just ignore those

[neat hamlet]

that just looks like its trying to parse it as c# or something

is it a .shader file?

[subtle thicket]

Oh right.

I TOTALLY know what I'm doing here

hmm... I'm not seeing how to 'equip' a material with this code shader

[neat hamlet]

whats the name on top

[neat hamlet]

should say "Shader "Something/whatever" " in the file

might say "Shader "ShaderGraph/TeamShaderUI" "

[neat hamlet]

hmm

and its a .shader file?

if you click it, any errors?

[subtle thicket]

oh never mind I got it

was editing the wrong one

[neat hamlet]

ah ok

[subtle thicket]

k moment of truth I guess

[neat hamlet]

if it still doesnt work your alpha is messed up :V

[subtle thicket]

sadness

[neat hamlet]

the preview doesn't show alpha either

[subtle thicket]

hmmm...

the spriterenderer version still doing fine

[neat hamlet]

can you dm me the graph, I'll have a look

[subtle thicket]

oh okay

[kind juniper]

Would be nice to hear if and how you solved it.

[fossil cloak]

Hey, i tried to recreate the Height from the URP/Lit Shader. But mine (left in the video) is not working like the one from Unity(right) when adjusting the sliders:

[meager pelican]

This is only a partial answer, since I assume you're doing the same thing with the Unity side as with the custom graph side, but...
If you're doing POM, you'd usually have a height map provided. That might tell you what is going on too.

[lucid scarab]

hi, is it possible to reproduce a 6 sided skybox shader in shadergraph?

[meager pelican]

https://gamedev.stackexchange.com/questions/183182/how-to-sample-from-six-cubemap-images-for-a-skybox-in-shader-graph

[lucid scarab]

thank you, but it don't fit my case. I have a render texture imported as cube

it's not possible to use render textures with cubemap 😦

now I'm trying to understand if it's possible to sample a texture imported as cube

[meager pelican]

There's a node for that.

[karmic hatch]

in shader graph, if you're using a transparent graph, there's an alpha slot in the fragment node

[lucid scarab]

?

[robust path]

Hi, I have an object with a custom shader that does not have emission on it, and I'd like to add emission
The shader is too complicated for me to mess with, it's from the asset store
My plan is to add emission in a separate shader, but I'm not sure how to do that - I tried using simple lit, but depending on my Sorting Priority, it either shows nothing, or it changes the entire look of the object (completely overrides the other shader)
How can I deal with this?

[kind juniper]

Firstly, you need to understand a few things about shaders:

• They define how an object is rendered. You can't "add up" shaders to the object as components. All you can do is either have several materials with different shaders, in which case the same mesh would just get rendered twice and one of the renders would overlap the other or they might even start z-fighting. Or duplicate the object and give it another material(but the effect is probably gonna be the same or even worse.
• Emission is usually just a color unaffected by lighting and shadows. You can achieve the same effect by just adding the emission color to your final color value that the fragment shader outputs.

As for a solution to your issue, modifying the shader (or using a different one) would probably be the simplest solution.

[robust path]

Thank you! This shader seems to be based on the URP SimpleLit, which pass should I edit for best results? I'm quite new to shaders, and the URP stuff is just intimidating

[kind juniper]

What passes does it have?

Maybe it would be easier to recreate the shader in shader graph?

[civic lantern]

Is it a HLSL shader?

[robust path]

ExtraPrePass Forward ShadowCaster DepthOnly Meta
Each except for ExtraPrePass has Tags { "LightMode"=passname }

[robust path]

yeah

[robust path]

Those are the names of the passes - I'm not sure how to better explain it

ExtraPrePass seems like the main custom thing

[kind juniper]

Forward is the one that defines the final color, so you should look at it's fragment shader.

[robust path]

will try!

[kind juniper]

What does the shader look like? Extra prepass is probably some intermediate calculations.

[robust path]

I'm not sure how to properly explain to you how it looks like - I'm kinda new to shaders in general
but yeah it seems like you're right, it mostly has a ton of function definitions, not much actual code

[civic lantern]

@robust path Been a while since I messed with written shaders, but if you see anywhere something like:

o.Albedo = ...```
You can try adding a line with 
```cs
o.Emission = ...```

[kind juniper]

I mean, what does it do? How does it look like in the scene?

[robust path]

there is no o.Albedo anywhere in the file

[civic lantern]

Is there anything pointing to albedo or color

Look for that

Look for the part that samples your main texture

[kind juniper]

or just look at the return value of the fragment shader - that's the final color.

[robust path]

Albedo is added to color 6 times in the forward pass

I mean it's in the code 6 times, somewhere in the forward pass

wait no

it's just

color.rgb += Albedo * mainTransmission

[civic lantern]

You should be able to add to that rgb.

To get emissive effect

[robust path]

yep, got it! Thanks!

it works

I didn't know emission was just adding a color, huh

[amber saffron]

AFAIK, URP height effect is using Parallax offset mapping, not occlusion (different node)

To properly apply parallax occlusion mapping, you also need to provide the primitive size : the world size of what would be the UV unit X and Y axes, taking the object scale into account.

[long lynx]

can someone explain to me why my sprites arent showing right ?

[regal stag]

Node previews don't show transparency, only the RGB data. But to fix it in the Main Preview / Material, connect the A output to the Alpha port in the master stack.

[long lynx]

yes thanks, just found it out

im new to this so. sry for the dumb question ll

lol

why is this my preview:

and this ingame:

[shadow locust]

Looks like lighting and/or a postprocessing Bloom

[long lynx]

thats the result when I remove bloom and global light

it really only gets white when I add my own material based on the shader

forgot to add textures

thought I didnt need to because I named the components right

but no

[queen lance]

Hello again - I'm having an issue with custom shader graph blocks.
https://gdl.space/atexoxajov.cpp
The output of this shader is always a black square. I have a couple questions which are difficult to test myself because there doesn't seem to be a way to debug shader code:
What's the range of a float of RGBA from Sample texture 2D? I think it might be 0-1 instead of 0-256.
Have I defined my array of colour values correctly at the top of this script? I can't seem to set pOut to be a value from this array.

the function that doesn't work is PaletteMatch_float

[shadow locust]

colors are indeed 0-1

[regal stag]

Yes, when you sample a texture it's typically a 0-1 range. So you may need to multiply by 256 before comparing
As for defining your array, I believe you should add static to the start. Otherwise it'll probably only return 0 (as the default is "extern" variable which marks it as a external input)

[queen lance]

thanks - it's still only doing black, but now it can actually read the values, I think, so that's good

[regal stag]

Afaik it should automatically assign the textures. _MainTex is handled by default, but for "secondary textures" you'd need to connect them with the sprite asset : https://docs.unity3d.com/Manual/SpriteEditor-SecondaryTextures.html
Make sure the name used matches the reference field of the property (under Node Settings, while property is selected that is). It's a bit different from the property name which is only for display purposes.

[lucid scarab]

is there any way to make dynamic skybox in Unity?

I think there is a big limitation with render textures

[queen lance]

It would seem my mistake was far dumber than I thought. I forgot to update the best distance value when a new best distance was found.

[queen lance]

It works almost perfectly now, thank you very much for your help

[fervent flare]

Given something like this, would there be some elegant way of randomly offsetting my textures UV's by X whenever the Sine value reaches its lowest value in the curve?

[reef owl]

I mean you could do something like this to generate a value of 1 around the time sin(t) = 0, and 0 any other time:

- invert abs(sin(t)) ( take -abs(sin(t)) )
- subtract some number n ( something like 0.8, so the output of -abs(sin(t)) now ranges from -0.8 to 0.2 )
- clamp between zero and one -> now all values should be zero or some small positive value
- round up

then you could just multiply that number by whatever offset you want, before you apply it

also you could adjust n to change the window that the shift is active in

if you don't want a sudden jump you could multiply by some amount instead of rounding up

@fervent flare bc I forgot to use a reply

[crude flume]

Hey anyone know a good shader that makes good water with crashing waves on the edge of it, similar to those dark stormy nights in horror movies and stuff

[tame topaz]

There are a few high quality ocean shaders on the asset store.

[vague spoke]

Does someone know how to make an interaktive shader for grass? I already one for Wind velocity (everything pixelperfect)

[undone anvil]

how to access secondary texture via Shaderlab ? i want to implement shader to UI canvas that can get 2nd Texture from sprite editor

[halcyon magnet]

Question. I'm trying to manipulate the vertex positions using a texture and, while the preview shows obvious distortion, the mesh I'm applying the material to remains unchanged.

[karmic hatch]

How is the mesh subdivided? If it's just a quad you're only going to be moving the corners.

[jade hinge]

Howdy peeps ; looking for some directional advice re "water":

I need a mobile (VR performant) water-shader or material of some kind. I don't need transparency (would be un-performant) or anything super fancy, I just want to give any kind of stylized impression that "this is a water surface"... Hopefully something that can work double-sidedly so that when underwater the player can see the under-side of the water surface...

the other limitations is that I'm trying to avoid real-time lighting of any kind, and that, ideally, it works for a sphere mesh (a 360 spherical water surface)...

scrolling some basic UV noise seems like the absolute simplest approach, but I was also hoping to integrate that with vertex manipulation...

So... if anyone has any insight about how i can do a minimalistic water shader as performantly as possible, would greatly appreciate it!

https://i.imgur.com/MPF523q.mp4

(the blue sphere /w the noise pattern is my current placeholder)

[undone anvil]

could u try to open wireframe and send this mesh screenshot again

alr did anyone working with softmask https://github.com/mob-sakai/SoftMaskForUGUI and using both custom shader and masking ?

try exactly resource example of custom shader config and i got this 😦

https://github.com/mob-sakai/SoftMaskForUGUI/blob/main/Shaders/Resources/UI-Default-SoftMaskable.shader

[visual ocean]

Hello! Has anyone experience with the use of Material instances for each gameobject in the built-in render pipeline?
What are the performance impacts? Especially on mobile? Would love to hear from your experiences

[rotund ingot]

Hello, I'm working on a triplanar shader and I'm trying to split the top from the bottom of the normal. The goal is to have the green only on the top, and have the rest be brown

[karmic hatch]

What does it look like in Unity's wireframe display?

Also depending on how large it is, you probably want a float multiplying the offset so you can change how much it's offset by (otherwise it's just a fixed 1 meter)

could multiply it by sine time or something for debugging, just to check that it's moving

[grizzled bolt]

@halcyon magnet With certain export settings the mesh may appear normal but get a scale of 100 or 0.01 which messes up object space effects

The rotations may get flipped which is likewise relevant when mapping a texture in object space

[true steppe]

Hey guys! Some parts of my textures appear pink only in the build. What could be the issue?

[quaint grotto]

how do you calculate the depth under a water plane?

im currently subtract the scene depth in eye space by the position node in view space

but im getting crazy bright white result when i put it in my base color

[harsh marsh]

Trying to make get a 3D pixel art style going. Currently, I'm trying to figure out how to add edge highlights to sharp edges on objects that are pointing towards the directional light of the scene.

For example, this screenshot

should have highlights like this

but I'm a bit confused on how to achieve this in URP w/ shadergraph

[kind juniper]

This kinda falls under the edge outlines category(with some modifications) which is a pretty complex topic with different possible implementations that have their own advantages and disadvantages. I suggest starting from researching how outlines can be implemented in unity.

[quaint grotto]

what causes this bug ?

[spiral agate]

2

[quaint grotto]

annoying flashes

[spiral agate]

how would i go about this?

[spiral agate]

saturate output, i believe it is caused by artefacts, not sure what your code looks like

[quaint grotto]

i saturate then i added a pow function

[spiral agate]

well, thats the pow function then

[quaint grotto]

is it cause a value in my output is exceeding 1 ?

[spiral agate]

use pow first, then saturate

[quaint grotto]

sure but 1 never exceeds 1 in a power function

ok good point

[spiral agate]

it might be negative values

since pow does not return negative values there must be some weird stuff going on at 0

[north verge]

how can i find 3d modelers & or animators?

i believe its called parallel prefix sum, but using max instead of add

but i really do not know how to implement this in a shader, i really could need some help here
please @ me so i can catch your message

[somber chasm]

So i've upgraded my project to URP and need to update one of my CG shaders, it's a very small shader (85 lines) but i'm at a complete loss of how to convert to HLSL

Essentially I have things like:

            UNITY_DECLARE_TEX2DARRAY(_MainTex);
            fixed4 _Color;

            sampler2D _OverlayTex;
            fixed4 _OverlayColor;

And UNITY_SAMPLE_TEX2DARRAY(_MainTex, i.uv)

Which are not compatible with HLSL?

[tardy spire]

Is there a good way to load a compute shader without referencing it in the inspector or putting it in a Resources folder? I'm kinda surprised there isn't a Shader.Find equivalent

[harsh marsh]

sure do enjoy a nice 3 hours of trying to figure out how to get unlit materials to receive shadows in URP 🙂

and im just stuck here

[north wren]

Is there any way to implement transparent and double sided shaders on mobile without huge performance hit? (using a specular shader)
I don't need a translucent material, just want the holes in my texture to be transparent

[quaint grotto]

ok im stuck i have a water plane and im trying to project caustics on to all the objects behind the water plane, but i seem to get stretching on the faces that vertical on the Y axis - how can i fix this stretching issue?

[kind juniper]

For something like that to exist, unity would need to load and cache all the shaders for you. There might actually be something like that in the editor namespace, but at runtime there's no need for that, so there isn't anything like that afaik.

[kind juniper]

The whole point of unlit is that they don't receive lighting it shadows.
But to help you with the issue, you'll need to share more context(like what nodes connect to this multiply).

[kind juniper]

Sounds like alpha clipping. Should be possible with an opaque shader.

[plush imp]

is it possible to always include shaders at compilation time?

i only found a way that works in editor because the relevant interfaces dont seem to exist in build mode

[kind juniper]

What do you mean by always include?

Include where?

[karmic hatch]

tbf you might also use unlit if you want to manage the lighting yourself

obviously not ideal circumstances but sometimes it's how the cookie crumbles

[plush imp]

unity's settings menu has under the Graphics option the

"Always Included Shaders:"
...
...

index

i want to not add the shaders there

but instead in code

to include the shaders at compilation time

and not include them using unity's pipeline that processes the project settings

[kind juniper]

By "compilation", do you actually mean the building process?

[plush imp]

i guess

[kind juniper]

I guess you could hook into the build pipeline somewhere to include the shaders..? But why not do it via the project tab..?

[night isle]

so i need a shader with multiple passes. right now i have 4 extra passes, one for each diagonal like this

however instead of moving it around, it would be better to just scale it from the middle like so

its guaranteed to be a plane, i just need the coordinates in terms of the plane

and im not sure how to do it

[night isle]

oh and also i need it to be from the centre regardless of its pivot

and scale out exactly n screen pixels on each side

also just randomly my shader stopped working, i got the message that line endings are inconsistent but i thought i fixed it in vscode

yet the shader is just pink and no warn or error messages

oh its because unity injected some code into my shader and messed it up lol

[night isle]

not even sure if this is possible actually

if anyone has a good pixel outline shader please let me know

ohwever it needs the be able to go outside the original sprites plane

[night isle]

heres what i need to figure out, a is the original size of the plane but i dont know how to get that

[meager pelican]

IDK what you mean.
if you don't know how to get (a), it is (b) -(2x). assuming they're centered.

But you'd have to know b.

You have to have one known, either a or b I'd suppose.

[shadow locust]

Yeah I'm a bit confused as to which variable you're trying to solve for here

Are you trying to solve for scale or a?

if it's scale then:
scale = b / (b - 2x);
if it's a then:
a = b - 2x;

if it's b then b = a + 2x;

[night isle]

yeah i need to know either a or b

[shadow locust]

You don't know either a OR b?

Or you're saying you know one or the other?

[night isle]

i know neither

and i need a way to get one of them at least

but im not sure if thats even possible in a shader

[shadow locust]

what data do you know and what data are you trying to find out

or maybe even better - can you explain the situation and what you're trying to do?

[night isle]

scale up a plane in a second pass of a shader

ive figured out the scaling by shifting the vertices according to their sign

which scales them by exact screen pixels which is what i need

but now i need to find the scale factor of that to use in the fragment shader so i can scale uvs down when i sample the texture

[plush imp]

to use it as little as possible

[grand jolt]

I have a generic question regarding Shader Graph, as it's a visual scripting tool and if i think about the underlying code, would it be better to use a single node and just route it to several input locations?

basically, if i attach a sampler state property to each SampleTexture2D, is that generating the code required for the sampler state multiple times? whereas if I use a single property and route it multiple times is that just using one set of code? or does it not matter?

I know it's probably micro-optimization if theres a difference but im always fond of knowing these things

[reef owl]

Do I need to declare a new sampler for every Texture2D I declare? if not, how can I determine when it's possible to use the same sampler across multiple textures?

[terse nexus]

How do I account for the offsets of sprites in my shader.
Texture number one is a texture split into multiple sprites (actually its a tileset)
Number 2 is world space auto tiled. It seems to add the offset of the sprite on the tileset to the offset though. So aligning tiles doesnt work

[gray harness]

any idea why this isnt working?

and the object looks black

if i do return float4(1, 0.8, 0, 1) it works

[regal stag]

Your property is named coluor but colour in hlsl

[gray harness]

oh

i see now

thx

[spiral agate]

how can i make a compute shader having a starting point, and checking anything before, comparing those 2 values and return max of both of them?

please @ me for suggestions

[quaint grotto]

why the hell is ComputeWorldSpacePosition function not available in shader graph yet they have that function in their api

[deft narwhal]

is there any way to have a shader use global positioning to make all objects using it have the texture line up? Like blenders "object" mapping option in the shader creator. right now all the meshes in my scene are somewhat different sizes so i end up making a whole new material to kind of line them up and i cant imagine thats good for file size

[quaint grotto]

strange, when i apply a local to world matrix to my material it doesn't seem to update 🤔

[kind juniper]

Use world position as uvs in your shader.

[low lichen]

This is a problem that can't easily be parallelized, so I wouldn't consider a compute shader to be the best solution.

[meager pelican]

https://docs.unity3d.com/Manual/SL-SamplerStates.html

[meager pelican]

You can do one each way an examine the code. The optimizer might just optimize excess samplers out, but I wouldn't count on it. If it were me, the most intuitive is to use one sampler and drag multiple output lines out of it to various things.

[harsh marsh]

found like 3 different tutorials but got a different broken result from each of them and none of them gave a github repo 👍

doesn't help that pretty much every github repo for such a thing is a post processing shader rather than just a normal material shader

If anyone has any github repo examples of outlines using depth normals in URP that is a single shader made in shadergraph that'd be great because I literally do not know how to continue

[halcyon magnet]

@karmic hatch @grizzled bolt I appreciate the help. The solution that worked for me without changing the wireframes were the following nodes:

[heavy stirrup]

Is there a way to override final blit pass to use our own uber post process shader?

[spiral agate]

i wouldnt know of any better solution than having a starting point, and checking the next (segment maybe?) whether its bigger or not, deciding max(x,y)

[kind juniper]

What do you refer to by "final blit"?🤔

[deft narwhal]

how do i do that exactly?

[sage ridge]

im not a 2d artist how to make 2d shaders like cool shaders for unity ?

[heavy stirrup]

it's a pass in URP that's literally called Final Blit

[kind juniper]

Depends on wether you're writing the shader manually or using a shader graph. In the latter case there's a position node that you can use to sample the texture. In the former it's a bit more complicated.

[kind juniper]

Hmm... I don't know much about the inner workings of urp. Might be worth asking in #archived-urp.

[quaint grotto]

how do apply a normal map only to the faces that have a normal facing up in world space

i applied my approach to colour and it looked fine

but as soon as i apply it to the normals it affects other faces

this is what i got

the idea being then if the face has a normal of (0,1,0) i multiply by 1 or i multiply by 0

but it messes up entirely

[kind juniper]

Could get the dot product of the normal vector and world up direction and push the resulting value through a step node to set anything below 1 to 0. Then use the resulting value as the mosifier.

[quaint grotto]

yeh i figured it out in the end its because the object was rotated 90 but there was like 0.0001 off so the step was rounding it up to 1 so i have changed the threshold now

damn float precision got me

im still struggling to understand if you need to multiply or add colours some times

im trying to add stronger caustics but its causing the blueness of the water to be less vibrant

very confusing on how im suppose to merge it to the colour of my water

[neat tendon]

can i make this a shader in unity

and can it work with triangulated ngons?

also each face is a seperate object in my project

idk i'm no shader god

[undone anvil]

https://www.youtube.com/watch?v=fu5HYNu-lw4 try this ?

i didnt go in deep yet sound like its should be your desire ?

[neat tendon]

yeah i just dont know glsl

or hlsl

¯_(ツ)_/¯

guess i'll go learn :|

[digital gust]

I am sure this is possible with shadergraph too

[karmic hatch]

It's not all that different from c#, syntax-wise

[spiral agate]

.

[steady ledge]

i exported height map from substance painter, but its adding like a outline to my character, how can i fix it?

[grizzled bolt]

If your height map uses black as a "neutral height" color, it'll be interpreted by unity as an indentation, and basically shrink the texture which makes pixels outside of the UV island visible
This will also happen if you use grey as neutral, but if the texture is marked as "sRGB"

[stable flare]

Hi I've been using a halftone shader i made and it works flawlessly.. Until there is a flat surface. It works great on bent surfaces as you can see on the horns, the back and the leg parts, but holyy is it so bad on flat surfaces like the gun or the two legs you can see in the other screenshot.

[loud dagger]

Hey all! How can I separate channels for the camera?

[amber saffron]

What do you mean "separate channels" ?
Notes :

• The camera position is float3, not float2
• You can use _Camera_Position.x, .y or .z to get individual axis values but ... I still don't see what you want to do.

[loud dagger]

Yea the float2 was just me playing around. https://www.youtube.com/watch?v=4P9Bifze8QY&t=609s
I'm kinda using this as a guide. I want to split the channels and just use X and Y. Honestly not sure why but I'm just following how he made it.

[deft narwhal]

anyone know why this shader isnt mapping to Y or Z correctly?

[amber saffron]

Are you using the world position as UV input for sampling ?
UV is a 2 coordinates vector, so the Z value of the position is ignored, and you are projecting the texture on the XY plane

If the model has proper UV coordinates, just use them with texture coordinates node, or use triplanar mapping node for world space coordinates

[steady ledge]

thanks, i couldint fix it, so i removed height map xD

[deft narwhal]

triplanar worked. thanks

[swift loom]

Does ComputeScreenPos do anything special to stretch the resulting normalized value somehow? Because I'm trying to use id as screenposition in a compute shader, however to get textures to work I have to add -1 after the texture width/height, which doesn't even work accurately all the time.

like (id.xy / (screenSize.xy - float2(1,1))) * screenSize.xy maybe to stretch it out?? not sure what the proper way to deal with this is

[swift loom]

^this seems to work at least...

[tight vortex]

Hey folks, I'm playing with simple parallax shaders and stumbled upon the classic "View Direction drives the offset" technique, which works fairly nicely. However, at more extreme angles the effect breaks down and the textures flatten. I think this is a common issue with the technique (as I've seen many games have the same side effect), so I'm wondering if there is another way to approach the effect, even if it's a bit more expensive?

[subtle thicket]

Why is there so much stuff missing now in shadergraph compared to what I'm seeing in these older tutorials?

now it's like this

I can't figure out how to replicate these shaders because stuff is missing, like alpha clipping, smoothness, emission, etc

I guess sprite mask is the same as normal

I'm trying to replicate a dissolve shader btw

Well I figured out step node is basically the new alpha clip

[grizzled bolt]

Well, not "new" since it works the same way in all situations
Alpha clipping is a particular way to do semi-transparent surfaces, usually for materials that are otherwise opaque
Sprite Lit doesn't use it because it's transparent to begin with

Sprite Lit also doesn't have smoothness or metallicness because 2D lights don't consider that

[karmic hatch]

you can add more onto the fragment shader

i believe if you right click on it it gives you things you can add

there are a lot

also i think alpha clip might need to be ticked in the graph inspector?

[subtle thicket]

Ah, thanks

Tst, I forgot the golden computer rule. When in doubt, right click everything

[grizzled bolt]

I guess the Sprite Lit could use emission, but for some reason doesn't

[grizzled bolt]

Yes, I believe adding block nodes to the stack doesn't by itself do anything if the shader doesn't support that block

The problem here being that Sprite Lit does not

[subtle thicket]

Yeah you still have to use step node

[cloud fossil]

Anyone knows how can I fix this issue?

I just put my blender work into unity and that's what I got (view first image from top)

[shadow locust]

You sure this is a shader issue? Just seems like a materials/texture issue

[quaint grotto]

how do we write code for lit shaders in urp the docs only show an example of unlit shaders

[fervent flare]

I need some help adding a random offset to a texture every x seconds

how do I get the time node to turn into a sort of periodic timer ? 🤔

[azure lichen]

Hey, quick question. I've got this gem (sry for the quality, it's an AR screenshot) and I'm trying to change its color values on buttonclick.

When I click the button, it changes the color, but it suddenly becomes a lot "brighter", causing the loss of reflection details

But the only thing I'm doing is editing the color values through script. Alpha is excluded already, because it's 255 on all of them so the only values changing are the RGB values

[shadow locust]

sharing the code would be a good first step

[azure lichen]

Well, in that case it's just public void Red() { _gemMaterial.color = new Color(255, 0, 6, 255); }

_gemMaterial color is public Material _gemMaterial

[quaint grotto]

does shader graph automatically account for what platform we are using for things like returning depth values because on some platforms it uses negative z

[shadow locust]

Color uses 0 - 1 values

everything you give it over 1 is going to be the same as 1

so your color is full red, full blue, full alpha, zero green

[azure lichen]

I'm still getting different colors though. Wouldn't I get the same color everytime if that was the case?

[shadow locust]

wdym

same color every time you do what?

Anyway you don't have to take my word for it

read the docs:
https://docs.unity3d.com/ScriptReference/Color.html

This structure is used throughout Unity to pass colors around. Each color component is a floating point value with a range from 0 to 1.

[azure lichen]

I'll go ahead and change it. Thanks for the answer

[neat tendon]

actually looking back on this i think i want something a bit different

The mesh

with diagonals removed

what i want

basically to just inset the edge of each shape

[neat tendon]

i've heard that you can bake some of this information into the mesh but i might still want to have meshes imported at runtime

[kind juniper]

You could loop the mesh vertices, identify the outermost corners, sort them in order and use to render separate lines either with a line renderer or a custom shader(not entirely sure about that one).

It would only be possible with convex shapes though I think .

Might be possible with concave too. But it would be several degrees of time more complex. Both computationally and implementation wise.

[neat tendon]

i was thinking maybe a multipass shader would work

scaling down each object then overlaying it ontop of the original

each face is a seperate object

but i'm not sure

[kind juniper]

Ah, of it's just the outline that you need, there are many techniques to get it done. Look up tutorials on outlines in unity.

[neat tendon]

is it much slower?

[kind juniper]

What is much slower than what?

[neat tendon]

a wireframe shader alternative

i imagine rendering each polygon twice could be bad for performance

[kind juniper]

Not sure what you mean by a wireframe shader since we were talking about outlines from my understanding.
But rendering the geometry twice is of course gonna be slower than rendering it once.

[harsh marsh]

hmm. It's difficult/impossible to see depth with my toon terrain shader. Any idea on how I can fix this?

[jade hinge]

this isn't a shader based fix, but perhaps you could imply depth by using objects of a standard size

eg, flower bunches, trees

[quaint grotto]

any one know what this means for my custom code?

void RGBSplit_float(float split, Texture2D Texture, SamplerState Sampler, float2 uv, out float3 Out)
{
    float2 offset = float2(split,split);
    float r = SAMPLE_TEXTURE2D(Texture, Sampler, uv - offset).r;
    float g = SAMPLE_TEXTURE2D(Texture, Sampler, uv).g;
    float b = SAMPLE_TEXTURE2D(Texture, Sampler, uv + offset).b;
    Out = float3(r,g,b);
}

[shadow locust]

what's line 303

[quaint grotto]

well according to the show generated code its literally just a comment line:

this is a custom function im using thats in its own hlsl file

not sure how exactly to get it to show me the exact line causing the problem

does my hlsl file need to include something for it to work ?

[kind juniper]

I'd check if you have other errors.

[quaint grotto]

where would it list other errors

[kind juniper]

If you select the shader, they should be displayed in the inspector

[quaint grotto]

the inspector for the SG only has this showing

[kind juniper]

Hmm

[quaint grotto]

maybe i need to restart unity or something

does my code look fine on the face of it ?

[kind juniper]

Perhaps the issue is not with the code but the custom function node settings?

[kind juniper]

I think it's fine.

[quaint grotto]

this is how its setup

[kind juniper]

Did you define the entry/exit nodes correctly?

[quaint grotto]

had uv set to float and not float2 but fixing that didn't change anything

it seems to talk about sampler and texture2d so i presume its the three lines involving the SAMPLE_TEXTURE2D

wait do the variables in the inspector have to be in the same order as the function's arguments

[kind juniper]

Yes.

[quaint grotto]

ok restarted unity and it seems to be ok with it now

¯_(ツ)_/¯

[kind juniper]

Probably the float/float2 issue use the cause and after fixing it, it just didn't take effect right away

[quaint grotto]

it seems to be ok with my variables not being in the same order as the function's parameters which is odd

[kind juniper]

Are they not? They seem to be from what I can see.🤔

Ah, the uvs and split are mixed up?🤔

Was pretty sure the order matters. Maybe your input gets cat to the other type?

But if it doesn't, that's interesting.

[quaint grotto]

i thought it was because they match by name

[kind juniper]

Ah, could be that indeed. Didn't think about that.

[quaint grotto]

ah damn it similar error popped up this time

even made sure all the variables matched and were in order

apparently cant convert UnityTexture2D to Texture2D<float4>

same function yet it was error free just moments ago

[kind juniper]

I guess the type used by the shader graph is UnityTexture2D. That's a wrapper around Texture2D if I get it right.

[quaint grotto]

how do i get the Texture2D then to use the SAMPLE_TEXTURE2D()

[kind juniper]

Thinking about it, do you really need a custom function there? You can do that math in the shader graph itself.🤔

[quaint grotto]

well im calling it a few times and it just makes the graph neater

its becoming spaghetti

[kind juniper]

Could make a subgraph or something, but okay.

[quaint grotto]

it already is in a subgraph 😛

its part of a bunch of other stuff

[kind juniper]

Make it a subgraph in a subgraph.😬

Check the manual page on how to sample a texture.
https://docs.unity3d.com/Manual/SL-SamplerStates.html
It should work without a macro. In fact the way you're doing it know could be the CG(built-in rp) way..?🤔

Hmm. Maybe not. The shader graph node uses that macro it seems.

[quaint grotto]

its weird because in the subgraph theres no error

but using the subgraph in the main graph the error shows

in the subgraph its fine

[kind juniper]

Perhaps it didn't recompile it?

[quaint grotto]

is there a way to force it

[kind juniper]

Press the save button?

[quaint grotto]

i do

[kind juniper]

Where does it show up though? And what exactly does it say?

[quaint grotto]

in the main graph

when i use the subgraph node

but if i open that subgraph

theres no errors in there

[kind juniper]

What does it say?

[quaint grotto]

still relates to the code i wrote my RGB Split function

[kind juniper]

What if you close the graph window and reopen it?

[quaint grotto]

hm that got rid of the error but now generates a new error in the console 🤔

Shader error in 'Master': undeclared identifier 'r' at Nodes/WaterAPI.hlsl(7) (on d3d11)

[kind juniper]

I think the issue is with the macro. Try using the way they do it in the docs page.

[quaint grotto]

oh you mean from the texture itself ?

[kind juniper]

Yes.

Maybe not. But it's worth a try.

[quaint grotto]

this is what i was referencing from when i wrote mine

but i wrote mine like this:

    float r = SAMPLE_TEXTURE2D(Texture, Sampler, UV - offset).r;
    float g = SAMPLE_TEXTURE2D(Texture, Sampler, UV).g;
    float b = SAMPLE_TEXTURE2D(Texture, Sampler, UV + offset).b;

[kind juniper]

Yeah, I've seen that too. But I just don't trust macros.

[quaint grotto]

ill try the other way to test it then

[kind juniper]

It could be that you pass in an expression to the macro or something. Since they're evaluated at compile time, who knows what it's expanded into...

[quaint grotto]

hmm now i got a new error entirely Shader error in 'Master': undeclared identifier 'OffsetUV_half' at line 198 (on d3d11) i've not even got anything with that name

seems to be happening every where

wonder if unity is just failing to compile properly or something

[kind juniper]

Hmmm... Does it appear in a compiled shader code?

[quaint grotto]

it seems to keep taking me to a random line with nothing there

dunno why these errors are so poor at telling what line it is

that texture error also seems to remain aswell

(╯°□°）╯︵ ┻━┻

[kind juniper]

Share the updated code.

[quaint grotto]

void RGBSplit_float(float Split, Texture2D Texture, SamplerState Sampler, float2 UV, out float3 Out)
{
    float2 offset = float2(Split, Split);
    
    float r = Texture.Sample(Sampler, UV - offset).r;
    float g = Texture.Sample(Sampler, UV).g;
    float b = Texture.Sample(Sampler, UV + offset).b;
    
    //float r = SAMPLE_TEXTURE2D(Texture, Sampler, UV - offset).r;
    //float g = SAMPLE_TEXTURE2D(Texture, Sampler, UV).g;
    //float b = SAMPLE_TEXTURE2D(Texture, Sampler, UV + offset).b;
    Out = float3(r, g, b);
}

i dont get why its saying converting UnityTexture2D to Texture2D<float4> though

the code seems fine it just seems to not understand the type

[kind juniper]

The other way around.

[quaint grotto]

wdym

[kind juniper]

It can't convert Texture2D to UnityTexture2D.

[quaint grotto]

no it says UnityTexture2D to Texture2D

[kind juniper]

Check the shader graph manual page on custom function node. Preferably version above 10.3.

See the last section "working with texture wires"

I think that's relevant.

[kind juniper]

It's definitely the other way around in the screenshot.

[quaint grotto]

it says UnityTexture2D to Texture2D<float4> for me

[kind juniper]

It says the opposite here though.
Anyways, check the docs page.

[quaint grotto]

yeah reading it now

[kind juniper]

I think the error was making sense all along. Although, not being very descriptive...

[quaint grotto]

right so i have to use type UnityTexture2D not Texture2D in my hlsl code

[kind juniper]

Yes

Does it work?

[quaint grotto]

no lol apparently that type does not exist

guess i got to find what file to include in my script to get it work

pain

[kind juniper]

Yeah, I guess you might need an include.🤔

Are you on urp or birp btw?

[quaint grotto]

urp

[kind juniper]

Okay

[quaint grotto]

whats birp

[kind juniper]

Built-in rp

[quaint grotto]

ohh

im on version 13 and still get these problems lol

do you know the location of unity's hlsl files to use #include ?

[kind juniper]

Actually, I don't think there's a need in include. Since it's part of the shader graph, unity should include all it needs.🤔

[cloud fossil]

Sorry I went to sleep, also yeah it is a texture issue I just couldn't find the texture/materials channel 😅

but is there any way to fix it?, I worked really hard on that model

[shadow locust]

make sure your materials are correct

[cloud fossil]

I tried saving a very simple blender project which contains a cube and a checker texture, that's it, and the checker texture did not work am I missing something?

[shadow locust]

yes do you understand how materials work in Unity?

Blender materials do not generally transfer to Unity

[cloud fossil]

I didn't know that 😅 ... , watching a tutorial rn of how to export

everyone tells me to 'unpack all into files' but I don't have that option??

[neat hamlet]

try UnityTexture2D and UnitySamplerState

[quaint grotto]

do i need some include file to use them ?

[neat hamlet]

nope

[quaint grotto]

a quick test seems to not find them

or is that because my hlsl file is standalone but shadergraph will combine it ?

[neat hamlet]

did you actually save the file 😛

[quaint grotto]

yeah its my visual studio saying it

[neat hamlet]

ok, I dont use the suggestions for shaders, its no use

[quaint grotto]

ah lol

[neat hamlet]

it works out of the box in this version

void Test_float(in UnityTexture2D _Texture, float2 UV, in UnitySamplerState sampler_Texture, out float testing)
{

     float r = _Texture.Sample( sampler_Texture, UV).r;
    testing = r;

}

The quick test I did

[quaint grotto]

is in important there?

[neat hamlet]

ehh not sure

the sampler naming might be

[quaint grotto]

oh the name needs to be sampler_TextureName ?

[quaint grotto]

copy pasted your code and got this:

i swear it doesn't regenerate or something

i dunno why its talking about Result_0

i have no variable with that name

[neat hamlet]

theres two _ _ there in __Texture I dont know if that makes a difference

also you didnt at a UV

Vector2

[quaint grotto]

oh i seem to have to close shader graph and reopen for the error to go away

thats annoying

[quaint grotto]

for some reason if i edit the code and hit save it wont update in shader graph until i reopen the entire shader graph

at least it works so thanks for explaining the issue with textures @neat hamlet !

[neat hamlet]

shader graph can still be buggy
glad its working now

[quaint grotto]

the docs do not do a good job at explaining so many things as a beginner 😄

constantly having to dig forums

[neat hamlet]

even for a non beginner its not easy :V

[quaint grotto]

yay finally got nice caustics working

oh wow gif totally compressed it to death

[craggy chasm]

Hi guys I have been trying yo implement metaballs, and use the code from this repo https://github.com/luke161/Unity-Metaballs-2D

This generated the metaballs on 2d objects but i wanted to generate metaballs on the UI and have no clue where to start from. Any help is appreciated.

[swift loom]

Anyone know if this is a correct way to approach it?

[winged sable]

I created this Shader to draw a perfect circle for one GameObject, but in 2D it does not respect Sorting Layers. I figure it, because i'm using a LineRenderer and the line overlap the material using this shader, but it doesn't when i use a material that uses Sprite-Lit-Default.

If i use Sprite-Lit-Default, it respect Sorting Layer. Is there something i can do in the Shader Graph that makes sure it works respecting the order of my layers?

I read i post in "stackoverflow" (but it is an answer from 2015) that in the shader code it needs to add ZTest Off so it wouldn't mess with the layer order.
Is that true? Or is there something i can do in shader graph ?

[stable flare]

Hi I've been using a halftone shader i made and it works flawlessly.. Until there is a flat surface. It works great on bent surfaces as you can see on the horns, the back and the leg parts, but holyy is it so bad on flat surfaces like the gun or the two legs you can see in the other screenshot.

[jade hinge]

@stable flare i think this is sort of an inherent quality of flat or near flat shading unfortunately

I have seen some art styles use painted edges and specs as pseudo-texture, but otherwise i think you could try and use bumps/ridges in your geometry to help ensure that your half-tone shader has places to transition on

eg:

ridges placed like that should at least impart some shading that helps with direction and depth

i really like the style but ultimately it does seem tough to work with 😄

[fervent flare]

Anyone know if its possible to add an offset to a textures UV's every X seconds?

Been trying to crack this since yesterday without using a c# script to control values

cannot figure it out though, it seems like shaders cannot store any data

[shadow locust]

shaders can't store data.
A material is basically a shader + parameters for the shader. You'd adjust some parameters on your material to do this

also the shader needs to support the params

[fervent flare]

I figured as much... so what I am trying to accomplish, is it not generally possible ?

adding amount X to an offset every Y seconds

[shadow locust]

of course it's possible

as long as your shader supports UV offset as a shader param

[fervent flare]

is it easy? would you be able to point me in the right direction?

[shadow locust]

I mean... what shader are you using?

Most of the default unity shaders support a UV offset already

[elder pivot]

https://www.reddit.com/r/unity/comments/z81jzs/material_for_image_ui_causing_random_black_bars/
basically my material on my UI Image is causing a blackbar
removing the material fixes the issue...but then my eyes look wacky so was hoping someone knows a workaround
got this advice from someone
"Looks like a shader issue to me, the EyesPaint material has the wrong one, or something wrong with it. Probably ask in the shaders channel"

nvm

"Oh, UI doesn't support Tight packing, and all our sprites has it enabled."

[fervent flare]

Well I am trying to create one in shadergraph. One that adds an offset of X every Y seconds. But without a C# script.

I just don't know what node sorcery produces this result

[shadow locust]

Use the add node

add your parameter to the UVs

and feed that result into the UV for sampling the texture

that's all

[fervent flare]

that doesn't add the value every y seconds though

[shadow locust]

no that's for your C# script to do

that's why it's a parameter

[fervent flare]

I am trying to do this only in the shader, without using a c# script (that's the thing)

[shadow locust]

you do Material.SetFloat or SetVector and feed data into the shader

[shadow locust]

why

it's quite standard to drive this stuff from the C# side

[fervent flare]

I imagine so, but is it possible without it ?

[shadow locust]

sure, there's the Time node

You'll just have no control to pause or manipulate it at runtime.

[vestal pelican]

So I'm currently into premature optimization, but before committing to a technique I want to ask for you guesstimation: I've been considering writing a terrain renderer that works soley by tessellating single quads and displacing with a height map. Tessellation factor being controlled by cam distance. Now there are voices that tessellation is expensive and only pays off in some cases (and especially only when having a dynamic height map). 15 years ago, bandwidth was a concern, but is it now better to just have a "high poly" grid and eat the bandwidth and potentially increased vertex count (in case I don't manipulate the mesh based on the camera position on the cpu, which again, would cause updating buffers). [i.e. keeping the terrain rendering as is?]

[fervent flare]

How would I go about doing that ?? Could you point me in the right direction ?

I don't really need any control over it, so that should be fine

I know how to add value X to the offset every frame relative to time but I don't know how to amount Y every S seconds (using the time node and without using c#)

[shadow locust]

to do what? Use the time node?

Put it into the graph

it has a bunch of options

it just produces a number based on the time elapsed

(or other things depending on what setting(s) you use)

[fervent flare]

just say you don't

it's fine

it's okay not to know how to do something

[shadow locust]

I don't play the negging game

[fervent flare]

I am trying to add an offset of amount X every 1 second only

not every frame

that is what I have difficulty with

I know the time node exists

And I know that I could do this with C#

[knotty juniper]

is the timer on a per object level or for the whole world?

[knotty juniper]

you could do it like this

(in the example the offset defined in the multiply and it gets added every 5 seconds

[craggy chasm]

If anyone here can provide me some information on this ?

[quaint grotto]

if you have two colours A,B and you use min() on them...what makes a colour more min than the other? are darker colours considered more minimum ?

so like a light blue vs a dark blue would min pick the dark blue

i want my shader to pick the darker colour of the two so i assumed min() would do that - if not what is a better way

[stable flare]

Thx man

[shadow locust]

min goes componentwise and takes the min of each

so if you have (1, 7, 2) and (4, 4, 4) the result will be (1, 4, 2)

[quaint grotto]

oh

ok i dont want that then

is there a way to pick a darker colour from two choices

maybe the magnitude ?

[shadow locust]

sure - convert the colors from RGB to HSV form and select the one with the lower V

[quaint grotto]

oh wait magnitude wont work either

[quaint grotto]

is that easy to do ?

[shadow locust]

here's some hlsl examples
https://www.chilliant.com/rgb2hsv.html

[quaint grotto]

thank you !

[fervent dock]

Does anyone know of a shader already created that can take an audio file added as a component to a 3D object and control transparency?

In URP ideal, but not necessarily critical

[gritty steeple]

Hi guys.. is there a shader which will only let the material appear under certain colors of light? Eg. words on wall with a blacklight

for urp*

[carmine jolt]

Have you had any luck using light layers in your own shaders? We're quite stuck.

[kind juniper]

There might be somewhere in the world if anyone ever needed that functionality and created a shader for it. But the chances that it's available online are quite slim.

[gritty steeple]

Yeah I'm struggling real hard to find anything online for it.

[kind juniper]

Which just means that you need to write your own.

[gritty steeple]

This is the closest I found, a reddit thread. https://www.reddit.com/r/Unity3D/comments/6inj6q/uv_light_reveal_effect_made_with_amplify_shader/ But it was done with Amplify 5 years ago.

I tried messing with Shader Graph, but I have no clue how it works lol.

[kind juniper]

Shaders are executed on the GPU they have no clue whatsoever as to what going on on the CPU side.
If you want a shader to use some data from the CPU side, you'll need to upload it to the GPU either as a texture, buffer or a shader parameter.

[kind juniper]

You'll need some kind of check or a function that transforms color data to transparency.

[quaint grotto]

if i use the same subgraph twice in my shader graph is that calling the subgraph functions twice ?

for example i have a depth to world subgraph. i need the result used in a few places - can i just copy paste the subgraph and that will still only be one call or will it be calling it for every copy of it i use ?

because its becoming spaghetti lines every where and its annoying as hell

[kind juniper]

Nah, I think that would call it twice. Visual scripting with complicated logic is gonna turn into spaghetti inevitably.🤷‍♂️

[quaint grotto]

damn

i would write the code but its a lit shader and no docs on how to write a lit shader only unlit

[kind juniper]

Use the connectors or whatever they're called. They can help you move the wires to the side so that they don't overlap other nodes/wires.

[quaint grotto]

yeah i'll have to

[fervent dock]

This part I understand, I guess the next question is has anyone translated audio volume level into data and how were they able to do so and then add that as a shader element.

[kind juniper]

The audio data you can probably get from the audio source in some form. You'll have to research that since I don't know much about audio. Then you need to normalize it on the C# side so that it corresponds to transparency value(0 to 1). Finally set a material property to move the data to the shader(might be easier to adjust the main color property's alpha)

[quaint grotto]

any one know a guide to writing lit shader code

unity only has docs for unlit shaders

which is annoying

[shadow locust]

for which render pipeline

[quaint grotto]

URP

ideally also HDRP but URP for now

i dont want to touch the actual lighting stuff - just want to write the visuals of the mesh before the lighting

i have no need for custom lighting etc

right now i use a lit shader graph but its becoming so complicated that i would rather write it in code

[shadow locust]

yeah idk lol.
One thing you could do is take your shader graph and view the generated shader

and go from there

[quaint grotto]

have you seen generated code 😐

its a mess

[shadow locust]

yeah >_>

[quaint grotto]

dunno why it has to be so ugly looking

[shadow locust]

that's kinda how generated code works

[quaint grotto]

one thing im considering as an alternative is one giant custom node function

[shadow locust]

yeh all the examples in the docs are unlit 😆

[quaint grotto]

and just write a massive function

[kind juniper]

It's not really supposed to be read by you.

And the compiler doesn't care how ugly it is.🤷‍♂️

[quaint grotto]

i know but they haven't provided an easy way to write custom lit shaders by code

[kind juniper]

You could try looking up the standard shader source code and copying some of it.

[quaint grotto]

would that work in urp ?

thought it was a whole change at this point

[kind juniper]

If it's the urp standard shader, yeah.😬

[quaint grotto]

what about in hdrp ?

You'd need an HDRP shader.

Maybe look at that. Someone made a urp lit for learning purposes.

[quaint grotto]

any one know how to convert depth node in eye space to be linear

it apparently isn't linear which is annoying

[gray harness]

can you mark vertex as not to render in vertex shader, so it doesnt render any triangle with it

?

[quaint grotto]

that would also skip two other vertices with that associated triangle so the only way would be to swap the winding order in the vertex array

could do that in a buffer of vertex data then pass that to the shader from compute shader for example

basically you would be flipping the normal of the triangle

but thats really only skipping for the fragment shader not the vertex

[swift oak]

Heyo fellow people.
So ive got a weird question for shadergraph.
I currently calculate the distance between two vectors, but i would rather like to keep track of what the current smallest distance is .

e.g if distance = 3 (store 3)
later distance = 1 (store 1)
later distance = 2 (store 1)
later distance = 100 (store 1)
Later distance = 0 (store 0)

The purpose of this is im making a beard cut shader but i need the hair to stay cut

The way i would do it in a script for unity is :

public min = 100;
public float distance;

private void Update(){

  distance = Vector3.Distance(ThingA,ThingB);

  if (distance < min){
      min = distance;
    }

}

This code would store the smallest value that this distance has ever been, but i have no idea how to translate this into shadergraph 😖

If anyone has been following this , I think a soln could be to store a number that i can compare to.
The problem is i cannot find a way to store a parameter to refer to again. The easiest if there were a setFloat() node equivalent inside shader graph.

[regal stag]

Shaders don't really have variables that persist between frames like that. This would be better handled in C# and send into the shader via a Float Property, material.SetFloat("_Reference", someValue)

[swift oak]

Ah i see. Ty for the response ❤️
But ive also realised that any property will be shared amongst all vertices, but require each vertex to store this distance.
I was so close to making this system and now i feel so far 😦

Considering there are logic gates im thinking of trying to create a flip flop of some sort and see if that works

[kind juniper]

Easy peasy. Make that calculation in a compute shader and save to a buffer/texture.

And reuse it wherever.

[regal stag]

Or do calculation in C# and store in mesh data, via vertex colors or an unused uv channel

[swift oak]

Great idea

[swift oak]

Smort, ty

[cobalt totem]

I'm trying to use some concepts from here for my custom ray marching code: https://github.com/SebLague/Clouds/blob/master/Assets/Scripts/Clouds/Shaders/CloudSky.shader

I'm using shader graph, so I'm trying to implement some equivalent functions.

float4 frag (v2f i) : SV_Target
            {
             ...
             float viewLength = length(i.viewVector);
             float3 rayDir = i.viewVector / viewLength;
             ...
             }

I have implemented as:

float viewLength = length(viewVec);
float3 rayDirection = viewVec / viewLength;

And this:

                float nonlin_depth = SAMPLE_DEPTH_TEXTURE(_CameraDepthTexture, i.uv);
                float depth = LinearEyeDepth(nonlin_depth) * viewLength;

Has been converted to:

depth *= viewLength;

Where depth is from the scene depth node shown above

But it seems no matter what I do, I just get a transparent cube

So the following happens next:

I get the distance to the box and distance inside the box, and advance the ray origin to the point that it intersects the box

I then need to set the step size, to do this I calculate (1 / numSteps) * dstInsideBox

and advance the ray using: rayOrigin += rayDirection

To convert from world coordinates to sample coordinates I do the following:
float3 samplingPos = ((rayOrigin - objPos) / objScale) + float3(0.5, 0.5, 0.5);

Where objPos and objScale are the world positions and scales of the cube being raymarched

A few things I'm unsure of:

1. Is the world view vector in shader graph the equivalent of i.viewVector?
2. Is the scene depth node the equivalent of calling SAMPLE_DEPTH_TEXTURE() followed by LinearEyeDepth()?

[night isle]

how do i get somehting like the Is Front Face in shader code

[regal stag]

For vert/frag shader can use the SV_IsFrontFace sematnic. So like, bool isFrontFace : SV_IsFrontFace in the vertex input struct (or param in vertex function).
For surface shader you'd want to look into the older VFACE semantic instead.

[regal stag]

1. Should be yes
2. You'd want to use "Eye" mode on the node to replicate SAMPLE_DEPTH_TEXTURE() > LinearEyeDepth()

[gritty steeple]

Hey, I'm a complete shader noob here so I apologize. I'm trying to make a Shader with Amplify that changes it's opacity or translucency based on a certain color light hitting it, think Blacklight or a Reveal Shader. How would I go about doing that? I apologize, but would appreciate some better understanding.

[hot lagoon]

Why is unity throwing this error in this line?

Shader error in '': Parse error: syntax error, unexpected TVAL_ID, expecting TOK_SETTEXTURE or '}'

[loud wolf]

Hi. I've got a problem. I just added post-processing to my VR project but it change my shader in a weird way : it duplicate the result of my shader (I just need the bottom in the second screen). How can I achieve that please ?

[low lichen]

When using bloom, you want to enable HDR rendering if you haven't already. That allows pixels to be brighter than 100%. Your bloom threshold is set to 90% now, so any pixel brighter than 90% will have bloom added to it. If you have HDR enabled and your threshold set to 100%, you can make sure your shader doesn't contribute to bloom if you clamp/saturate the color to 0-1 before outputting it.

Alternatively, you can clamp it to 0-0.9 if you don't want it to contribute to bloom with 0.9 threshold, but that will also make it darker.

[low lichen]

Sorry, I think I misread the question.

[loud wolf]

I check HDR mode and I add the Threshold but that dosen't change anything x(

the post process is for an other shader (outline) but for this shader I don't need post process so how can I avoid that please ?

[low lichen]

Try clamping/saturating the base color.

[loud wolf]

How can I achieve that please ? I'm new to Unity shader ^^'

[hot lagoon]

can someone help a sec here too after you finish there pls?

[low lichen]

Put a Saturate node in between the Lerp node and the Base Color output

[loud wolf]

no changes

[low lichen]

Maybe the alpha too

[tardy spire]

I'm learning how to modify mesh data from a compute shader and am trying to get my shader to support 16 and 32 bit indices via a shader keyword.
I have a base Deformer.compute shader that provides helper functions for working with the raw mesh data which I include in other compute shaders. At the top of the shader I have a keyword

#pragma multi_compile INDEX_FORMAT_16 INDEX_FORMAT_32

and further down I have a function for reading an index from a byte address buffer which I want to use the keyword

#ifdef INDEX_FORMAT_16
const uint raw = index_buffer.Load(bit_index);
return asuint16(raw);
#else
return asuint(raw);
#endif

I thooought this was correct? but when I try to set the keyword from C# I get an error saying Local keyword INDEX_FORMAT_16 doesn't exist in the compute shader.

if (indexFormat == IndexFormat.UInt16)
    deformerShader.EnableKeyword(new LocalKeyword(deformerShader, "INDEX_FORMAT_16"));
else
    deformerShader.EnableKeyword(new LocalKeyword(deformerShader, "INDEX_FORMAT_32"));

I'm guessing I've made a silly mistake/misunderstanding

[loud wolf]

YOU SAVED MY LIFE ^^ ! THX A LOT

But I've got an other problem since while. I've got a line that cut the material how can I remove it please ^^ ?

[low lichen]

Did you write this shader yourself? I've never seen names assigned to Program or SubProgram.

[low lichen]

Have you tried using multi_compile_local or GlobalKeyword instead?

[low lichen]

Is it only there with post processing enabled?

[loud wolf]

no It's the case even if post-process is disabled

[hot lagoon]

no

i didn't

or well, i did

but i reseted my pc and had to decompile them back

[low lichen]

Right... Well that doesn't look like correct ShaderLab syntax. The decompiler probably isn't generating correct syntax.

[hot lagoon]

oof

time to find a better one

[low lichen]

Does it help if you rotate the mesh so that line is towards the camera? I'd guess this has something to do with the order of the triangles.

[loud wolf]

It towards the camera

[low lichen]

Are you using Additive blending?

[loud wolf]

what is additive blending ? ^^'

[low lichen]

It's one of the blend modes you can choose from when making a transparent shader. I don't use Shader Graph, so I don't know where the option is, but I imagine it's in the same place where you switched from Opaque to Transparent.

[loud wolf]

It's already transparent ^^

[low lichen]

Sure, but there are different types of transparent. Fade, additive, multiplicative, pre-multiplied.

[loud wolf]

I'm with alpha ^^

Oh my god i'ts working with additive thx 😍 !

[loud wolf]

If you have time can I ask you a last question please ^^' ?

[low lichen]

Sure

[subtle cove]

Can anybody tell me where I can find the "Enable" node: ?

[cobalt totem]

Thank you! I'm getting somewhere now, the last thing I need to figure out is how to clip out the black background:

[regal stag]

Pretty sure this is a Boolean Keyword, named Enable. Can create it in the Blackboard, then when dragged into the graph it creates a node like that

[subtle cove]

What is the Blackboard?

[patent plinth]

@regal stag I saw your stylized water shader, would you mind sharing the tech used ? 😆

if I'm not mistaken Unity retweeted that too

[regal stag]

It's the window that contains properties & keywords. There's a button in the top right of the graph to toggle it

[subtle cove]

Ok

[subtle cove]

But I got a new problem.

[regal stag]

It's Gerstner Waves, if you want to look that up. Catlikecoding has a tutorial

[patent plinth]

Thanks!... Heading there now 👍

[subtle cove]

https://youtu.be/SOK3Ias5Nk0?t=405 There in that exact second, you can see the shader graph for spherical world bending. I wanna do that. But why does the transform node looks like this (weird):

[loud wolf]

I want to make this type of outline in my project : Glowing (not necessary with light), round border and diffuse like the first picture. I want this shader be able to be adapted with every mesh that I want and if it's possible, I want that the material of the shader will be a secondary material of the object (like in the second picture). However, I was looking for a tutorial for this type of shader but I find one complicated tutorial and moreover, it was not adapted to URP : https://www.youtube.com/watch?v=SMLbbi8oaO8&t=52s . And the other videos that I've fond just present some paid assets from the asset store. I've been looking for this since a while (1 mounth and a half TwT). How can I achieve this effect please ? No matter if it's shadergraph or shadercode ^^

[loud wolf]

If you want to talk in private message, it was not a problem for me 🙂

[regal stag]

Would be due to the Power nodes, as they don't support negative values. Might be a problem for vertices past the world origin, but you'd need to test it in the scene and see if it affects things.
If it doesn't work, maybe an Absolute node before the Powers would do what you want?

[subtle cove]

I don't completely understand your suggestion.

Like where should I insert it?

[subtle cove]

nevermind

It works now I think:

[wind canyon]

Hey, I think I need to texture the inside of this laser beam but I'm not sure how. Doesn't appear when you're inside of it which isn't what I want.

I've seen people say you've gotta use a shader but I have no idea what to do lol

[simple oak]

Hey, i got a question.
why is the black fabric only shown from the outside?

everywhere else it looks like this

[knotty juniper]

the geometry is one sided
unity will cull the backside unless explicitly told otherwise by the shader used on the material for that mesh
the better option is to have one mesh face for the outside and one for the inside

enable back face culling in your 3D software to see how it will be in unity

[low lichen]

This effect requires a custom post processing step. In URP, that would be done either through the Post Processing Stack or as a custom renderer feature.

[loud wolf]

Thx. Did you know how to do that please ^^' ?

[simple oak]

disabled it

and still looks like this

[low lichen]

It's not something that can be easily explained to someone who is new to shaders and I don't have time to make it for you.

[loud wolf]

Ok fine no problem. Thank you so mush for your help ^^

[subtle thicket]

Having trouble implementing a dissolve shader on an unlit material. The same shader works perfectly on a lit material, but on an unlit material it causes the transparent space around the sprite to become black when fully dissolved

Here's the relevant part. The 'split' is the main texture opacity.

whereas if I set the material to 'lit shader' it works fine and there's no black outside the sprite

(the glowing parts not being dissolved is a separate issue I haven't figured out yet)

[regal stag]

Looks due to negative values. Try a Saturate node after the subtract. (It clamps between 0 and 1)

[subtle thicket]

Yup, that worked! Thank you.

Oh, the reason why the glowing part isn't getting erased is because that part of the sprite is fully white, so step doesn't get rid of it. Any solution other than using an image editor to change it form white to one pixel off-white?

[grand jolt]

How does Graphics.Blit and such keep the ordering of operations intact?

[subtle cove]

After a lot of testing..

Now the objects and the player itself sort of float on top of the "cursed" plane.

Like 2 meters above them.

How can I fix that?

[quaint grotto]

this is getting on my damn nerves now, can any one tell the difference between my code in the sticky note and the subshader setup in this image???

i get completely different results using my code setup versus the subshader but they look identical to me

[shadow locust]

seems equivalent to me. You sure your inputs are correct?

[subtle thicket]

Turns out the solution was to saturate before AND after the subtract node

[subtle thicket]

Anyway to use dotween on shader propterties, like colors or floats?

Figured it out. You have to do this:

[quaint grotto]

how do you create custom SG nodes but not as in a custom code function - like an asset for the asset store

is it just subshaders at this point ?

[subtle cove]

Why are objects on my world bending shader floating like 2 meters above the plane, just following this video?: https://youtu.be/SOK3Ias5Nk0?t=405

[supple leaf]

Hey, im using the URP Decal Shader for my project. i created a new material from the shader but unity doesnt seem to like it even though its the original decal shader. does someone know how to fix that?

[meager pelican]

https://alexanderameye.github.io/notes/rendering-outlines/

[loud wolf]

Thank you very mush ^^. However, I've got a problem : it's my first time writting shader code so I don't know how to implement it ^^'

[cobalt totem]

How can I store the result for a fragment to be re-used between frames?
I've tried the following:

RWBuffer<float> buf1;
RWBuffer<float> buf2;

void Raymarch_float(...){
  if (t > 5) {
    Out = float4(buf1[0], buf2[0], 0, 0);
  }
  ...
  buf1[0] = someComputation1;
  buf2[0] = someComputation2;
}

But I'm obviously doing something wrong

(this is HLSL)

[loud wolf]

And I saw in the document that this type of render need performance. Or I made a VR environment where I activate the shader when my controller pass hover an object so is this dangerous to implement it ?

[swift loom]

is this the correct way to clamp a texture in a compute shader??

{
    Filter = D3D11_FILTER_MIN_MAG_MIP_POINT;
    AddressU = D3DTADDRESS_CLAMP;
    AddressV = D3DTADDRESS_CLAMP;
    AddressW = D3DTADDRESS_CLAMP;

};

or am i missing something

tried simply typing "Clamp" too but idk. I haven't found a page that really explains the values to use nicely.

like there's this but very hard to decipher https://learn.microsoft.com/en-us/windows/win32/direct3d9/effect-states and this https://learn.microsoft.com/en-us/windows/win32/direct3d10/d3d10-effect-states

in a nutshell this is all i'm doing but it keeps wrapping a pixel.

[haughty moat]

https://docs.unity3d.com/Manual/SL-SamplerStates.html "inline sampler state" should work in compute too and save you a lot of headache. Like Clamp_Point_Sampler

[swift loom]

ok ill try that thank you

but also does that mean i really only need one sampler?

if they all use the same settings

[haughty moat]

If you only need one type. I think so. There might more to it, but not that I'm aware

[swift loom]

is the point of sampler_MainTex to inherit the settings of the maintex really?

cause if so that makes sense

but anyway ill try it

[haughty moat]

yeah, texure settings in the editor control the sampler that Unity will create

The doc explains it ok, basically some api let you separate textures and samplers

[swift loom]

Yeah that seems to work. 👍

still losing a pixel at the bottom of my my sprite that uses an atlas however... not sure where in my math there that would originate.

[haughty moat]

Question/thoughts. I have an ocean surface, an sometimes some faces get rendered through the water, which is expected, but ugly. How would I go about discarding pixels that are behind the closest face of that surface ?

[swift loom]

Not that it helps anyone but I'm pointing to the atlas (ex. x40 y40) but since we're starting at 0 with the id it's getting shifted one pixel to the left on the texture so the x and y of the rect needs to be adjusted +1. 👍

[surreal locust]

I have this code: materialNormal.SetFloat("_MagnetMask", magnetPercent); and it works, but the material is modified persistently

Should I create a new material runtime and work on it?

[shadow locust]

yes

you can also use MaterialPropertyBlocks if you want to make non persistent per-renderer changes

[surreal locust]

which one is better?

[shadow locust]

they do different things

[surreal locust]

I'm reading doc of materialpropertyblock
Note that this is not compatible with SRP Batcher. Using this in the Universal Render Pipeline (URP), High Definition Render Pipeline (HDRP) or a custom render pipeline based on the Scriptable Render Pipeline (SRP) will likely result in a drop in performance.

I'm using urp

so it's better for performance to create a new material in awake and use it

I have only one renderer with this material so I can use both solutions

am I wrong?

[shadow locust]

if you only have one renderer using it it's probably not a huge deal either way.
BTW if you use myRenderer.material that automatically creates a new material

Actually only if there's other renderers using the same mat 🤔

[surreal locust]

    private void Awake()
    {
[...]
        mRenderer.material = new Material(mRenderer.material);
    }

[cobalt totem]

In my shader I want to update only certain pixels each frame, and re-use pixels that aren't updated. I'm using shader graph and an hlsl script and was wondering what the best way of accomplishing this would be? Is there a way to render the entire screen as a texture and use the previous frame's output as an input texture to shader graph? Or would that be too slow?

[shadow locust]

If you use a compute shader you can modify a texture as you wish (updating or not updating whichever pixels you want), then use that texture in your rendering shader.

If you want to use the entire screen output as a texture for a shader - that kinda sounds like PostProcessing

so maybe you're looking at making a custom post processing effect

[cobalt totem]

Hmm, actually I guess I don’t need the entire screen, just the pixels of the object I’m rendering

[grizzled bolt]

What kind of effect would it be?

[cobalt totem]

I’m trying to understand temporal reprojection but want to start with a really basic version first

I’m ray marching a volume and done some optimisations to get it down to 20ms but want to push it further by only raymarching partially and blending the results over multiple frames

(Or maybe I could do a high quality ray march for some pixels and a low quality one on others?) I would just need the pixel position (x,y) coords

[deft narwhal]

recently upgraded to HDRP and ive had a slew of issues but this one makes the least sense. its only got 1 texture on the pink parts, and it has a texture but the pink makes it look like theres a 2nd texture missing underneath. it only does this on a few of the windows despite all windows sharing the same texture and model. very confused

[shadow locust]

magenta means you have a missing shader / material or a material using a shader that isn't compatible with HDRP

[quaint grotto]

would underwater caustics be in the emission channel or the albedo channel

kind've confusing

hard to know what goes where

[deft narwhal]

well yea but theres only one texture on there and that texture is fine with everything else

[shadow locust]

it's not the textures

it's the materials

[deft narwhal]

oh just saw the tab on top. deleted extraneous material. thanks

[grand jolt]

where do I plug this

[knotty juniper]

from what i can read online the paralax uv channel goes into the textures UV cordinates
and the depth offset can be enabled and connected on the master node

[grand jolt]

what's the master node

[knotty juniper]

the one labeld "Fragment"

[grand jolt]

connected to the ao?

[knotty juniper]

no to depth offset (you need to enable that first )

[grand jolt]

where do I enable it

looking for it rn

[knotty juniper]

this in in HDRP

[grand jolt]

what

I'm on urp

[grand jolt]

do I have to switch to HDRP?

[knotty juniper]

not sure what renderpipline supports that

does it not show for you?

from what i can find at least at
Jan 2021 it seems that URP does not support it

and still not supported in 2022.2

[grand jolt]

nope

eh I guess I'll have to switch to hdrp

aaaand everything's pink

[grand jolt]

yeah it's too laggy

@knotty juniper what version of unity did you say supported pom on urp again?

[knotty juniper]

"and still not supported in 2022.2"
aka not a thing in URP

[grand jolt]

that's the latest?

[knotty juniper]

at least not with shadergraph

that is the current beta

[grand jolt]

well shit

normals are fine anyways

[knotty juniper]

for most cases yes

[grand jolt]

how about realism

idk I'm not really sure what to do in unity anymore but I've always wanted to get really realistic water so

I'm doing that

¯_(ツ)_/¯

[grand jolt]

how did I scroll a texture again? @knotty juniper

[knotty juniper]

this would use a signe singal to offset X any y of the cordinate

[grand jolt]

yes but instead of doing that it changes its color

[knotty juniper]

tiling and offset only works with UV cordinates
you have to use the value in the texture sample node in the end

keep the UV inpuit to the tiling node empty or intput the UV 0

[grand jolt]

it's not a single texture it's 2 which I want to scroll in opposite directions

so which ones do I plug?

[knotty juniper]

scroll them independent and then combine them after that

[grand jolt]

that's what I was trying to do

but the thing changed colors

I basically want them to be tiled automatically depending on the object's scale so I don't have to tweak it each time I change something

and at the same time move around

do I just tile the final moving result?

[knotty juniper]

you could plug your tiling valus in tile offset node

[grand jolt]

it just kind of flashes

[knotty juniper]

no no no

[grand jolt]

also why did the normals change color

I changed the texture type to normal map and now it's just a single color

[knotty juniper]

because you are doing it wrong

[grand jolt]

well how do I do it right

istg this worked before for the other water shader what is going on now

now they're gone altogether

[grand jolt]

oH

why do you have to multiply by 1

[knotty juniper]

you dont its just so you can adjust it that just some demo values

[grand jolt]

oh is it for speeding up

or slowing down

[knotty juniper]

correct

if you want to have control what axis it should scroll input a vector 2 into the multiply

then you can controll the speed and direction for each axis independently

[grand jolt]

the scale will make them be proportional to the size of the object right?

Ophélia are you writing an actual paragraph or something

I'd like to be able to represent a texture by values given from the user, could be either floats or integers...
not too sure how that would be done! I put something together real quick that does just that, check it here => https://github.com/OpheliaVRC/ShaderStuff/blob/main/TestShader4x4.shader;

I'd like to know how actually that would be done, a better approach, just anything different... like maybe provide a texture and then change each pixel of it to the new given values?

how would you go about it?

[grand jolt]

like

converting an image to numbers?

that's more than doable

almost, numbers to image yes

[knotty juniper]

sure you can do set pixel via code

[grand jolt]

code! you mean C#?

[knotty juniper]

correct

[grand jolt]

the thing is... I'm not allowed to use that...

it should all be part of the shader itself

[knotty juniper]

then how are you setting the values to the shader/Material?

or better
what result do you want to have?

[grand jolt]

numbers

lots of numbers

yeah this looks bad

any advice to make it look good

[grand jolt]

a full texture!
the user is gonna be able to provide the values from the shader GUI aka material in the Editor.

oh

like

[knotty juniper]

you could color / modify a existing texture before displaying it in the shader with the values that the user gives you
but this will not make a new texture asset

[grand jolt]

you for some reason manually type in the values of an image

and use that

instead of painting it normally like any sane and normal person would

"Innovative"

how do I untile this

so it looks natural instead of this tiled abomination

istg like 80% of the reason stuff I make in unity looks bad is because, and solely because of tiling

[grand jolt]

limitations are the reason, I'm only allowed to provide the image values via the AnimatorController by making a bunch of AnimationClips and use the controller Parameters in something like a BlendTree to drive the shader values, which would be pre-animated.

[knotty juniper]

something like this?
https://github.com/Unity-Technologies/TilingRandomization

[grand jolt]

yes

there's also that it looks too flat and too shiny in some way

pom would've helped...

[knotty juniper]

pom is the the solution for water vertex offset and normal should do it

[grand jolt]

ok

I'll try putting it into position

I can't plug it into position

why?

how do I plug it into position

[grand jolt]

it's okay, I'm fine with that! not interested in making a new asset, however!
will this also allow me to change the current texture's resolution?

and either way, how would I go about modifying each pixel of the texture?

so I'll just adapt everything to this

[knotty juniper]

you cant change the texture at all you only can read the texture and combine them with the color values you have and then display them

so no texture resolution change

[grand jolt]

nvm I can't

@knotty juniper how do I even set it up

[knotty juniper]

figure it out

or dont use it

[grand jolt]

I'm trying

yeah it doesn't work for this

[knotty juniper]

check the example shader

[grand jolt]

as I said it doesn't work for my node setup

unless you can save the resulting normal into an animated texture

that just loops

[grand jolt]

I checked and it doesn't work for what I have

any alternatives?

[grand jolt]

ok got this, so since I can't change the resolution of an existing texture in a shader, I think the way I'm doing it currently is the way to go?
that's if you already checked it... I'm not too sure what's exactly happening, but the final result is exactly what I've been looking for, however,
due to my shaders lack of knowledge, I wasn't too sure if what I'm doing is even right to begin with, but it works!

with that said, should I stick with what I have, or could it be done in other better ways? limited to shaders
