How do I add normals onto an .obj?

[worldly drift]

You usually create them with the modeling software th obj is modeled with.

Alternatively you could try setting Normals to Calculate in the models import settings. But I doupt this will create good looking normals

[glacial pond]

I've been trying to make a model, everything is there but the textures wont load for the model, if that makes sense.

[worldly drift]

Did you add a material and assign its texture to it?

[regal stag]

Will want to make sure the model is uv-mapped too if you're applying textures

[glacial pond]

The materials are in the obj, the textures just aren't applying to the model rn, like

I actually think I might have it

[worldly drift]

Take a look at the material settings. Is there a texture applied to the texture slot?

Can anybody help me unclutter this matrix mess?
This is what I had to do to make my shader work with multi pass, single pass instanced and for normal cameras:

#ifdef UNITY_STEREO_INSTANCING_ENABLED
#if UNITY_UV_STARTS_AT_TOP
output.positionCS.y *= -1;
#endif
const float4x4 projection = unity_CameraProjection;
const float4x4 inverseProjection = unity_CameraInvProjection;
#else
const float4x4 projection = unity_CameraProjection;
const float4x4 inverseProjection = UNITY_MATRIX_I_P;
#endif

I build the shader so it worked with stereo instancing and than found out that the matrices dont work out in the other cases

[distant sleet]

This raytracer is so unoptimized my gpu is crying

How do I access the shader graph blend node opacity parameter through c#?

[sullen jungle]

Hey, I'm still very new to shader development
I am working on a project that has already pre-existing shaders scripts(FlatKit)
I want to create curved world effect which I have already do in Shader Graph but the issue now is that all objects in the scene is using FlatKit but still I want to add my curved world effect to this FlatKit

How can I do this?

One best way I want to try to achieve is by converting the curved world effect to a shader script(Using the compile button in inspector)
Issue is:

• I don't know to write code with shader(Just through shader graph)
• I don't know how to import the curved world shader to one of the FlatKit shader

Can someone advise me on what I can google/research on how to implement this and if there's any advice to share with me?

[meager pelican]

It looks like FlatKit integrates with the Curved World asset. See the FlatKit "Releases" info section on the asset store.

Short of that you'd have to learn shader programming and convert the various shaders, I'd guess.

Questing.. has anyone developed a decent parallax shade that uses a 2d photo and its depth map to simulate semi 3d, similar to how Facebook 3D photos works in unity?

the screenposition is handled differently in shader graph

[sacred trellis]

did something happen to the "3d with extras" pipeline? it doesn't look like i have it for some reason

[dim yoke]

not pipeline, it's template. is uses build-in render pipeline same way as regular 3d project

[distant sleet]

Hi, just wondering if anyone uses visual studio as their IDE for shaders

I'm having a problem with UnityCG.cginc

The code runs fine when tested as the file is located and included, but in my IDE its unable to get any of the methods from this file so it always shows errors

Anyone know if theres a fix apart from including the entire UnityCG.cginc path?

[lavish oasis]

which side looks better? ||left is the default urp shader, right is custom||

it should look like "Sapele Pommele wood"

[distant sleet]

Even this still doesnt fix it which is weird, again the code is still running its just an issue with the IDE

[signal niche]

Hi, which shader graph should I use to create a shader that will prevent the image from going out of the scrollbar masking?
how come the UI/Unlit/Transparent default shader can work? What am I missing?

[distant sleet]

so annoying

the kernel is invalid and I dont even know why because it doesnt see the in built shader functions

[distant sleet]

Hmm I'm having some trouble with UNITY_SAMPLE_TEX2DARRAY so if anyone can help thatd be great

I think it may be diffuseTextures being a Texture2DArray but I'm unsure what type it should be

Found someone with the same Q and they got 0 answers https://answers.unity.com/questions/1820814/how-do-i-pass-a-texture-2d-array-into-a-function-a.html

[regal stag]

Texture2DArray is fine but you also need a SamplerState samplerdiffuseTextures.
There's probably also a UNITY_DECLARE_TEX2DARRAY macro that'll do both for you while also switching to sampler2D for the platforms that use that.

[distant sleet]

I did that

but I'm passing in the declared tex2d array

But I see, so I need that sampler state

Tysm

let me try it

The errors gone now which is awesome but I have this instead

Kind of a pain when my IDE doesnt know what the functiosn are lol

[distant sleet]

float3 diffuse = UNITY_SAMPLE_TEX2DARRAY(diffuseTextures, float3(uv, obj.index)).xyz * obj.diffuse;

[regal stag]

Ah, you need to use the LOD version probably. Don't think you can use the regular samples in a compute shader

[distant sleet]

obj.diffuse is a float3, and diffuseTextures is a Texture2DArray passed in my main .compute file declared as _DiffuseTextures

[distant sleet]

Ahh thank you so much!

Man theres barely any examples or documentation on this

Oh so it was because the name of my texture was different in the function params and main compute

so it did generate sample_DiffuseTextures

but not samplediffuseTextures

[regal stag]

Yea

[distant sleet]

Hm its really annoying having them in different files so I may pass in the samples diffuse/specular/refl as an argument instead

[regal stag]

It uses Stencils. Shader Graph does not support them yet (and so doesn't have proper support for making UI shaders either). You could generate code from the graph and add them though (but then it's a code shader now and if you want to edit the graph you'd need to re-generate and do this again)

e.g. https://github.com/TwoTailsGames/Unity-Built-in-Shaders/blob/master/DefaultResourcesExtra/UI/UI-Default.shader
In Properties,

_StencilComp ("Stencil Comparison", Float) = 8
_Stencil ("Stencil ID", Float) = 0
_StencilOp ("Stencil Operation", Float) = 0
_StencilWriteMask ("Stencil Write Mask", Float) = 255
_StencilReadMask ("Stencil Read Mask", Float) = 255

then

Stencil {
    Ref [_Stencil]
    Comp [_StencilComp]
    Pass [_StencilOp]
    ReadMask [_StencilReadMask]
    WriteMask [_StencilWriteMask]
}

[distant sleet]

Its like a hydra

fix 1 error and in return 3 more

Yeah the problem is

if I have them named the same this error wouldnt happen but then

I'd have to declare sampler_DiffuseTexture twice

because if I declare it in my .compute, it says its being redefined

if I dont define it in my cginc, it says unkown identifer

[regal stag]

Are you declaring it in the .compute before the #include? That should stop it being an unknown identifier

[distant sleet]

Oh its that simple haha

Thanks

Wait but

Wait lemme test it

YES

Hell yeah tysm

@regal stag but I'm kinda confused, I'm including the cginc in the compute and not vice versa

So how come defining the sampler in the compute via DECLARE_TEX2DARRAY also defines it for the cginc?

Or does that function define it in a broad scope that encompasses all the files involved in compiling

[regal stag]

As long as the DECLARE_TEX2DARRAY is defined before that include, it'll work.
Don't think of the cginc as a completely separate file. It's like, you copy the entire contents and paste it in place of the #include line, then it compiles.

[distant sleet]

Ah I see, yeah then it makes sense

thats awesome

Man but Ive had this other problem with the damn thing Ive been tryna figure out forever and its so weird.. for some reason

diffuse uses specular textures, specular uses refl and refl uses nothing

I've triple checked when I'm passing it into the shader its really weird

I guess maybe I made a mistake somewhere

[signal niche]

Thanks i try it later!

[distant sleet]

Refl uses di what the hell

Yeah i'm 100% sure im passing it into the shader correctly

[distant sleet]

Finally figured it out

In the CopyTexture step when Im copying from all the meshes to a list it ended up mixing them up and I think its because of the function taking a second to execute

[distant sleet]

Yeah I have no clue how to fix this lol

[dry oasis]

I have this dither outline shader. The outline isn't being drawn (only when its the first pass). I cant fin any fix to this, I'm pretty new to shaders. So I honestly have not really a clue why the stencil buffer wont render the outline.

https://paste.myst.rs/o6c298cp

[sullen jungle]

Hey
Is there a tool to convert shader graph to shader script(Is it called a shader script?)
Or does the compile button do the job?

[royal jetty]

Hey, do you know if this is possible in a compute Shader to take a 3d model as parameter and duplicate it ?
For example if i want to use a compute shader to generate grass, is it possible to take a mesh as input for grass blade and not generate the mesh from code inside the compute shader ?

[late needle]

Hi, I'm working on a Hololens project that requires we NOT use the HDRP or URP. So, for a task I've got in front of me I figured out a littel shaderlab and wrote a very simple shader to move UVs around and displace verts. However, I did not write it with Single Pass Instanced rendering in mind, and I can only see the models with that material in one eye when I deploy the app to my device. I'm trying to google this, but I keep finding info on URP and HDRP instead of the default base rendering system. If anybody has a link or something or can dumb down what I've got to do to a fifth grade level that I can understand (:)) I would greatly appreciate it

[regal stag]

Should be a View Generated Shader button at the top of the Shader Graph asset (or for older versions, right-click the master node in the graph itself)

[regal stag]

The docs here go through the setup : https://docs.unity3d.com/Manual/SinglePassInstancing.html

[distant sleet]

I'm still unsure about this so if anyone could help thatd be great

it isnt 100% related to shaders

the issue is all on the CPU side

[late needle]

yall are awesome ty so much

[distant sleet]

Graphics.CopyTexture(ResizeReformatTexture(rtMesh.diffuseTex, TextureFormat.RGBAFloat), 0, 0, _DiffuseTextures, index, 0);
Graphics.CopyTexture(ResizeReformatTexture(rtMesh.specularTex, TextureFormat.RGBAFloat), 0, 0, _SpecularTextures, index, 0);
Graphics.CopyTexture(ResizeReformatTexture(rtMesh.reflectivityTex, TextureFormat.RGBAFloat), 0, 0, _ReflectivityTextures, index, 0);

[late needle]

it's unlit

[distant sleet]

ResizeReformatTexture alters the texture via copying it to a RenderTexture, altering it and then copying back

[late needle]

literally nothing else but moving uvs and verts

and displaying color texture

[distant sleet]

but then when i add all of these to the Texture2DArray its all the same picture in each index

[distant sleet]

Its not the resizing thats causing all 3 Texture2DArrays to be the same

[regal stag]

URP doesn't really do multi-pass shaders. Either just separate them into two different shaders/materials, or provide the second pass with a custom LightMode tag, e.g. Tags { "LightMode"="Outline" }. Then use the RenderObjects feature on the Universal Renderer asset, with Outline as a shader pass tag (under filters) to render it.

[violet olive]

Ello.. So I downloaded a free asset, but its all pink.. Looks like it's something to do with the shaders ... is there a shader pretty universal? The model was on standard.. I got a couple working, but some of them remove the albedo.

[regal stag]

Could probably send the vertices, indices, and other data you need for the mesh in from a C# script. Don't work with compute shaders a lot but maybe look at ComputeShader.SetFloats / SetInts to set arrays.

[distant sleet]

Even using Texture2DArray.SetPixels didnt work (I used Texture2DArray.apply() too)

It still copies the same image to all 3 Texture2DArrays even though they are 100% different

[royal jetty]

from what I've seen now we use compute shader with buffer to generate geometry, so yeah i think itterating over the mesh vertices and triangles to add their data to the the render buffer may be a solution

Btw i found your blog once by doing research on coding shader on urp, greate ressources !

[regal stag]

If the model is using the Standard shader and you're in URP you will want to swap it to the URP/Lit shader which is the equivalent. I assume that's what you already are doing. The MainTex property was renamed to BaseTex so you will need to reassign that texture manually.

Could probably also use the "upgrade materials" option to do it automatically. See https://docs.unity3d.com/Packages/com.unity.render-pipelines.universal@11.0/manual/upgrading-your-shaders.html
Or for 2021.2+, https://docs.unity3d.com/Packages/com.unity.render-pipelines.universal@12.0/manual/features/rp-converter.html

[violet olive]

Ah thanks I just found the URP shader setting. I guess Standard is just for a normal 3d project?

[regal stag]

Yes, Standard is for the Built-in render pipeline / 3D template.

[violet olive]

I'm sure I'll get to that stuff on the unity learn path eventually.

[regal stag]

If it does the same with both SetPixels and Graphics.CopyTexture, is it the ResizeReformatTexture method that's causing the issue? What does that look like? Might also be a good idea to start a thread so it's easier to follow

[violet olive]

I've got a bad habit getting carried away with stuff.

[late needle]

You are basically shader jesus cyan

i hope you get paid for this

[regal stag]

I don't get paid, just like helping out

[late needle]

the hero we don't deserve

[sullen jungle]

Hey guys.

Situation:

• Want to implement curved world effect to multiple materials in my scene
• The materials in my scene are already using FlatKit shaders which are shader scripts and not shader graphs
• The curved world effect is in shader graph but I figured out how to convert it to shader script

Problem:

• I want to add the curved world effect to all the FlatKit shader scripts like a subgraph so how can I do that?
  like making the curved world effect shader script into a sub shader script

Please tag me on response

[grand jolt]

I've gotten a lot of shader jobs lately and I'm kinda wondering: do other shader artists always start from scratch without peeking at Shadertoy for ideas? 🤔

[sullen jungle]

I believe artist gets a better hand at being creative with shaders while like a programmer(code in c# side) like me I need source of inspiration just to get some visual ideas

[grand jolt]

I see. So it's not cheating 😎

[sullen jungle]

By any chance, do you know how to import/use a sub shader script into another shader script?

My brain is frying trying to find how to do that

[grand jolt]

Extract your shader passes into separate headers then just include them in each shader.

[sullen jungle]

Okay I'll google how to extract the shader passes :p
I'm still new to this and trying to figure things out

[grand jolt]

That just means creating a new header like MyPass.hlsl. And you cut and paste all the code between HLSLPROGRAM and ENDHLSLPROGRAM into it.

[sullen jungle]

Is there a resource maybe you can share with me because things aren't very clear and simple

I already have curved world shader graph that I turned into a shader script(Used View Generated Shader) and it's full of code
I want to use whatever is happening the curved world shader script to effect the shaders that I imported it into

[grand jolt]

You could put your curving into a function that takes a position vector, normal and so on packed into a struct and returns that struct with processed values. And put that function into a header.

Then any shader that needs it can #include "thingy.hlsl" and call the function.

[sullen jungle]

Does the thing.hlsl have to be an .hlsl file not a .shader file

[grand jolt]

Yeah. Shader includes are just snippets of code. When you include them the compiler just copies the text from them and pastes into your shader.

[sullen jungle]

Damn things got complicated

[shadow osprey]

I am getrings this phenomena on my water surface created with Gaia. I imported my scene into the „Hurricane VR Physics“ Sample Scene and reassigned all variables. After building the project on my quest2 all looks great besides this and I am getting double vision on my headset when enabling Post Processing on my camera object… Any idea what I can try to fix this?

[umbral mountain]

question : for those who use hlsl where did you guys learn it?

[distant sleet]

normal mapping is op

[distant sleet]

I spent 1 hour trying to figure out why my mapped normals looked like this

Until I just realized the solution was literally just transposing a single matrix

just transpose(TBN) was the solution for a 1 hour problem 🤦‍♂️

Might need to remove whatever you have in the Alpha port, just set it to 1.

[fleet rampart]

anyone having experience with adding materials via texcord

Sorry to bother, but I've added the tag and removed the stencil, I add a lightmode tag and the object stops rendering. But it keeps not rendering even though I have the tag in there? https://paste.myst.rs/1ggvkk40

[daring summit]

Hello. I want to use Unity's 2D Lights in a way that when an enemy sprite is iluminated it fades out of view (possibly changing the alpha) It seems a way of doing would be getting the light data from the light object and passing it on to a shader. According to this link https://docs.unity3d.com/Packages/com.unity.render-pipelines.universal@13.1/manual/ShaderGraph.html it is possible to create your own sprite lit shader but I have no idea what kind of node could give the light output. Or maybe I am way of base. What do you think?

[fair spear]

Hi, sorry for bothering. I'm trying to make some objects fade when it's too close to the camera (like how in Genshin, there's a dither effect when your character is too close to the camera). I followed this tutorial: https://www.youtube.com/watch?v=rVeS7oh3oug and copied the Shader Graph that Pablo made. The thing is, after tweaking some values, it works on objects close to the spawn point, but after a certain distance, the faded objects somehow show up again even though it's close to the camera (I'll show how it looks like). I've tried tweaking the graph, I've tried changing the MinDistance and MaxDistance values again but nothing seems to be working. I presume it's cause I'm using Cinemachine to operate the camera. Does anyone know what I'm doing wrong here?

Top: How it should look like (and how it looks like on objects close to the spawn point)
Bottom: How it looks like on objects far from the spawn point (there's a sprite hidden behind the wall)

And here's the shader graph I used for those 2 walls and the values

[green holly]

Anyone know how to code a ui globe like shader?

I mean the globe should behave like it has a level topped gas-liquid filled inside?

[fringe hound]

Coucou ! : )
I have this annoying thing. Each time I move a preset in my shader graph, the volume in the main preview become blue. I have to move it manually in the main preview window so it could show the changes. Is there away this could be updated automatically? Am I doing something wrong or is it this way it works anyway?

[regal stag]

It is meant to update automatically, not sure why it isn't. The cyan usually means the shader is compiling but it shouldn't take that long really. Have you tried just restarting Unity?

[fringe hound]

@regal stag maybe it is because there is a texture containing a video? I have restarted Unity and also upload the lasted version ( 2021.2.8f1 ) in case. It still the same. The strange thing is that nothing happen if I don't move manually the shape on the main preview. It could stay blue all day

[regal stag]

Maybe, I haven't used a video texture in SG before

It is happens with regular textures too, might just be a bug

[fringe hound]

Might be. Hum..Bug life : )

[regal stag]

The custom lightmode won't render by default. As I mentioned in the previous answer you should use the RenderObjects feature to then render the pass, with the same tag in the pass names, also filtered to transparent since your shader is in the transparent queue.

The alternative is just to split the passes into two separate shaders and apply both materials to the MeshRenderer.

[regal stag]

The Sprite Lit Graph still won't give you access to the lights afaik. You might need to look at how the default Sprite-Lit shader works and replicate that.

Can anyone recommend a mirror shader for VR that works in single pass?

[dry oasis]

I forgot to mention I was using that, sorry.

[dry oasis]

When I add the light mode tags in the render objects it stops rendering, I’m assuming that’s because I don’t have the transparent filter on

Dont worry about it anymore. I got it to work and the effect looks kind of shitty with the way that I'm doing the outline, Thanks.

So I'm making a water shader, and I like it a lot so far, but there's a big problem.
There's an obnoxious white outline around objects not making contact with the water

How can I hide the thin white outlines on non-colliding meshes?

Weirdly enough, the issue does not present itself in the editor

hi all, can someone help me with this issue im having?
i followed this tutorial to create a wobble shader (https://www.youtube.com/watch?v=xDCRah7BbIo) however when trying to apply it to my image it does not display correctly

can someone help me find where i've gone wrong, or if this can be applied to UI images

[dim yoke]

If you use msaa, try to turn it off. msaa often makes edges look weird.

That doesnt happen in editor because editor camera doesnt use anti aliasing

post processing anti aliasing like fxaa should work fine tho.

@bronze viper if you scroll down on this page, youll find bgolus deep explanation to this and some links to fix that https://forum.unity.com/threads/jaggy-white-pixel-artifacts-on-edges-with-specular-and-antialiasing.320984/ . It seems to be quite complicated problem and id probably just use fxaa if possible

[silk sky]

is it possible to move an offeset by a certain amount each X seconds via graph?

I'm trying to create a dance floor and want to move the color texture based on the squares

[regal stag]

You want to Floor/Ceil/Round the time

[tired spire]

folks, im wondering how to achieve the effects that the light dots can move along the given paths/roads which could act like the traffic in game. some hints would be awesome https://gfycat.com/criminalquarrelsomediscus

[grizzled bolt]

Depending how distant it is you can fake it by various ways
One that comes to mind is simple light dot particles fired along the roads at various intervals
Another is to make mesh strips following the roads with UV maps set so that when you scroll a dotted texture along its length it creates the illusion of cars moving and making turns

[tired spire]

yup,i tried using particles system but it could end up costing too much CPU performance,not ideal. scrolling textures probably is the way 🤓 i tried but not looking good at some angles and not realistic cuz all the light move with the same speed

[glacial pond]

anyone have a problem with a side of a mesh being see through?

[shadow osprey]

Does anyone know why my water reflections look so shitty in VR and in Game View it looks perfectly fine? Everything looks pixelated on my Quest2 but in game view it looks great. I am using Gaia with XR Support in Unity 2020.3.25f LTS. When I turn post procespon it looks better but I get double/cross vision . I am going nuts please help 🥺

[bronze viper]

So if I remove the specular aspect it should in theory go away?

[distant sleet]

Ah god I still can't figure out global illumination in path tracing

When I'm returning the "color" for each object, the only one that returns color is the light source

Hence the only way the rest of the scenery is illuminated is that light bounces off it and into the light

I think I need to read more because I'm probably missing something even though it seems correct in theory

Radiosity looks nice though

[wintry summit]

Is there still any way to make grass swaying on wind shader in HDRP that doesn't look weird when camera moves? Changing Position nodes to absolute world doesn't do anything

[dim yoke]

no idea tbh

[bronze viper]

it didn't

[dim yoke]

@bronze viper atleast you can use something other than msaa

[bronze viper]

yeah i'm using fxaa

[marble thicket]

hey guys i am trying to make a shader, but my shader is white when i put it on top of a material. Why is this happening?

@shadingpeople

[regal stag]

Make sure you click the Save Asset button in the top left of the graph

[marble thicket]

Oh my god thank you so much

[grand jolt]

hello! i downloaded a shader but i dont know how to install it in unity

[tame topaz]

You don't, it's just a script file. Put it in your project assets folder like you would anything else.

[grand jolt]

@tame topaz are you here?

ok so i installed the unitypackage file and this folder appeard here

but i dont know what to do next

[tame topaz]

Make a material that used that shader.

[grand jolt]

ok

wait

and how is this going to work

i mean

i want everything to change

I mean

The shader changes the graphics

right?

i mean what do i do with that material?

[tame topaz]

Put it on a mesh.

Surely you know how materials work by now, based on how often you ask for help here.

[grand jolt]

So shader doesnt change the whole graphics?

[grand jolt]

Yes i do know

I thought that shaders changes the whole graphics

[tame topaz]

Shaders give the materials their functionality to make whatever mesh they're assigned to, appear in a particular way.

[grand jolt]

Oh

Okay thank you

[south acorn]

Kind of stuck here. New to the shader graph. I know how to make the top brown but how could I make the bottom a darker brown?

[robust wharf]

Hey, how does one use sprites in the shader graph? In BluePrints you can just create a 2D texture node and select a sprite from the list or drag in a sprite from the assets explorer, but that doesn't seem to be the case with the Shader Graph.

[robust wharf]

I'm not at my computer to check, but you might try a Rotate and Offset node.

Bring the position node in as the UVs and see if adjusting the Y value for offset doesn't get the green to the bottom.

If it does then you can just use the same methods you used to turn the bottom brown.

[south acorn]

In the end I just use a Lerp node with 2 different colours and the Y position in object space as the T since I was only trying to colour the object based on the height and it came out ok I guess. I just forgot to mention it. But thank you!

[grand jolt]

i changed the shader to my material and nothing changed

literally

it looks the same

[tame topaz]

What was it supposed to do?

[onyx coral]

Hello guys
Please, could anyone that knows Shader Graph help me?

I have a "Shockwave" effect

I've created a mat using this shader

I've put this mat as a Renderer Feature thanks to Blit

But now I need to know, how can I "activate" the effect?

in other words, how can I make a boolean that, if set to false, would prevent all the calculations from being made from the shockwave

and how can I make sure that when I put this boolean to true, the shockwave starts from the beginning (instead of it starting mid-"animation")?

[wary horizon]

keep the gameObject disabled, and enable it when you want it to do its thing

[onyx coral]

I don't think it would work tho

Because the shockwave effect won't necessarily start from its beginning

as it uses Time.time

excepted if there's something I'm missing

[regal stag]

Use your own float property instead of time, then you have full control over when it begins

[onyx coral]

And I would update it by script each frame?

hmm

[grand jolt]

idk change the graphics?

https://github.com/RetroGEO/reroStandard

this is the shader

someone told me that it makes the standard pipeline to look better

[tame topaz]

It says it's the Unity Standard Shader right in the description. What was it supposed do to your materials?

And how does it make it "look better"?

[grand jolt]

I dont know

Look

Can i dm you?

@tame topaz

[tame topaz]

No

If you don't know what look you're trying to achieve, then nobody here can really help. You're just wandering in the dark at this point.

[grand jolt]

Ah sorry

I already dm you

You can look in dms. I told you everything about my problem

And if i type it here its going to take a while so

[vocal narwhal]

The hell

You need a #📖┃code-of-conduct refresher.

[grand jolt]

oh

sorry

ill send the messages here then

Hello
My game should look like this with the shader

but mine looks like this

my friend told me to install the shader, and change the material shader to rero standard

and i changed it but nothing happend

what do i do

[grand jolt]

here is link to the shader

[vocal narwhal]

No idea what you're talking about specifically

[grand jolt]

i installed a shader

[vocal narwhal]

Turn down the smoothness if you mean how it's slightly shiny

Add emission to the eyes

[grand jolt]

i want to look like here

no

no emission

i deleted that

[tame topaz]

Also, lighting your scene to match your reference image is necessary.

[vocal narwhal]

Again, no idea what you mean specifically

[grand jolt]

bruh

[grand jolt]

you see that?

[grand jolt]

the graphics are different here

i dont know if its from the light

[tame topaz]

It's lighting, it's post processing, its everything.

[grand jolt]

wait

post processing

which effect do i need?

i've installed it but i dont know which effect i need

[tame topaz]

Tinker around with it and find something that works.

[grand jolt]

i tried

maybe its color balance?

oh guys

it was that simple

i had to change the color space from gamma to linear

[modest spoke]

Hey, I'm looking to make a sort of night vision shader, and it's hard to find information on how exactly to do this with a physical object. I'm looking to create something like this, but working in the dark. Does anyone know how to somehow boost brightness looking through the object with a shader?

Sort of like this effect in Boneworks:

for reference, this is what it's like when it's dark

[meager pelican]

I enjoyed these articles, and thought others here may as well, so sharing:

No warranties, express or implied 😉 Cannot comment on Unity-specific uses/compatibility.

[grand jolt]

I'm so confused

Is it either all or nothing with URP? Not finding any up to date tutorials explaining why it does this and none of the comments related to it

oh apparently probuilder has it's own shaders that URP doesn't know about so it refuses to upgrade them

now i need to fix the textures maniacally flickering

[grand jolt]

dude, it was a complete ball ache and it took me longer than I'd ever hoped, but these textures look 800000000x better

[grand jolt]

Is Vegetation studio Pro better or Nature renderer+Shader?

[vocal narwhal]

If you're using URP you need to use URP materials

[grand jolt]

Yeah I figured that

but I have another issue now

[silent sluice]

How do i make a window which doesnt get any darker when on other window?

i need the shader file

[grizzled bolt]

I guess you'll want to look into how to enable ZWrite

[gritty harness]

why cant i make shader graph?

[grizzled bolt]

Which rendering pipeline and unity version is your project on?

[gritty harness]

what is a rendering pipeline?

2020.3.23f1

[grizzled bolt]

Shader Graph is only for the universal render pipeline and high-definition render pipeline in all editor versions before 2021.2

[gritty harness]

so can i not use it?

do i need this?

[grizzled bolt]

Your project currently does not support it

[gritty harness]

so i can never use it?

[grizzled bolt]

That's a bit extreme don't you think

[gritty harness]

so is there a way i can use it or not?

[grizzled bolt]

Install a rendering pipeline that supports it or upgrade to an editor version that supports it even without the rendering pipeline

[gritty harness]

what render pipeline is best for trash pc (my pc)?

[grizzled bolt]

Universal Render Pipeline

[gritty harness]

ok

[grizzled bolt]

The install process has many steps so look up instructions before you try

[gritty harness]

ok

[digital vector]

Heyo, i'm trying to follow this guide here https://github.com/Unity-Technologies/Graphics/blob/c6ae7599b33ca48852eddd592b3e40f33f2dd982/com.unity.render-pipelines.universal/Documentation~/writing-shaders-urp-reconstruct-world-position.md right now, but all i get is some white noise.
I have both, Opaque-Color and Opaque-Depth enabled in my URP settings, and i can perfectly sample Scene Color. Only the depth is screaming at me in an unwillingness to cooperate

Here is an image of where i copy pasted the attached code into unity (minus thelast depth < 0.001 / > 0.999 check )

When i copy paste the thing without modifications, it just remains black

and here a last demonstration of the scene color working (i scrambled the channels)

Ok so it only doesnt work in viewport

... ok no it works in the tiny camera preview, and only there

[digital vector]

This is the result of this guide btw https://www.cyanilux.com/tutorials/depth/#reconstruct-world-pos

[inland zinc]

im trying to make shadows work with my shader but i cant seem to get it working
i have shadows, shadow cascade and soft shadows on but nothing is working

[digital vector]

Looks like my custom shaders arent writing depth as they should... but why does the preview then work

[digital vector]

WORKS! Added the depthonly pass and that did the trick

[steel notch]

Hey so I'm trying to make a shader where you have some plane that when it intersects with another mesh, only displays the parts where it and the mesh are intersecting. For example if the plane was intersecting a sphere right down the middle, the plane would only display a circle.

[neat hamlet]

check out the stencil buffer example @steel notch

[surreal oriole]

You guys, is there a good tutorial to learning shaders for beginner?

[swift loom]

Is there a UNITY_SAMPLE_TEX2DARRAY variant for tex2Dgrad ??

i don't know if it's that big of a deal to use a normal tex2D inside a [loop] for loop

it works 🤷‍♂️

[south granite]

Hi, can you suggest a great tutorial for beginners for Compute Shaders>?

[primal harness]

https://www.youtube.com/watch?v=BrZ4pWwkpto

Does anyone have some example shader code for receiving shadows in URP?
It's hard to find any up to date code for receiving shadows for URP

[wise skiff]

hey would it be possible to make a shader that takes the density of a certain particle in an area and based on it, the area is fully filled witha a color?

[silver sparrow]

is there a list of functions available for shaders such as clamp, saturate, frac etc.

[slender prism]

ok so this is a rly dumb one
but a few months ago i accidently did smth that made everything purple when there isnt a material applied to it
and bloom doesnt work either after i did that

im assuming its a shader problem

but idk

[silver sparrow]

alright so i found this site: https://developer.download.nvidia.com/cg/index_stdlib.html, does anybody know if this is up to date or the correct site i should be looking at?

[umbral mountain]

Anyone could have an ideas why my shader is purple in scene & game but it shows the shader in prefab viewer?

[regal stag]

I'd say this is more up-to-date : https://docs.microsoft.com/en-us/windows/win32/direct3dhlsl/dx-graphics-hlsl-intrinsic-functions

[silver sparrow]

aight thanks

[regal stag]

Magenta means there's an error in the shader. You might have errors in the console / inspector on shader asset.

[regal stag]

It sounds like you might have tried switching to a different render pipeline? e.g. Built-in to URP or HDRP? They require different shaders so if materials in the scene is still using Standard ones it'll show as magenta. URP/HDRP also uses different post-processing. I don't think there's an automatic way to convert that, I think you need to manually set it up again.

If you want to go back to Built-in RP you can remove the pipeline asset under Project Settings -> Graphics. Should work assuming you haven't converted any materials yet. Can then uninstall the URP/HDRP package.
If you want to switch pipeline look at the appropiate docs (e.g. pinned in the #archived-urp / #archived-hdrp channels) for setup instructions. I'd recommend backing up the project before doing anything.

[pulsar imp]

Hi 🙂 I'm working on a sand shader and i got stuck. Is it possible to get rid of these seams (near red marks) between the meshes, something like blending on the border of the mesh? The meshes have the same material.

[daring dew]

If your albedo texture is already worldspace, you can use a custom pass (if you are in HDRP) to blur the normal buffer, on sand meshes,
Or you could also override the mesh's vertex normals to make them all point up, in a consistent direction to iliminate the seams.
Or use a single mesh (like a terrain, and paint displacement on it, for everything, instead of using multiple meshes ?

[pulsar imp]

@daring dew Thank you, could you give me some example custom pass with blur the normal buffer?

[south creek]

Added URP shaders to my Udemy shader course https://bit.ly/urpshaders https://youtu.be/9xGCKeec2qE

[lean lotus]

hey is there any way to output numbers from a compute shader, similar to how in cuda you can do printf?
I wanna return numbers for debugging purposes, but idk

[shadow locust]

You can write data into a ComputeBuffer and read them out on the CPU side.
Or use a tool like RenderDoc

[lean lotus]

oh really?
and I thought renderdoc didnt really like to work with compute shaders?

[shadow locust]

It might not, there's some tool that does it may or may not be RD, I've never done it personally

[lean lotus]

computebuffer may be my best bet then thx

[shadow locust]

I usually debug via ComputeBuffer or via positioning things in my shader in a really hacky way to show values of things lol

[lean lotus]

fair enough

[lean lotus]

ugh debugging byte shenanigans in a compute shaders is frickin annoying

[fervent flare]

Does anyone know how to get smooth lerping from 0 to 1 and back to 0

in shadergraph ?

I'm playing around with the Time nodes Sine Time output

but that's far from smooth

[white marsh]

So ive been learning how to write shaders for a while now, so I wanted to try to write a basic shader with unity's surface shaders. The problem is that i cant get the transparency to work with it. Ive set the render mode and que, set zwrite and blend mode. Only thing missing is to set the alpha but nothing happens. It renders just like normal, unaffected

[south creek]

Sin time range is -1 to 1. Use an add node to add 1 and a divide node to divide by 2. Then you get smoothly changing 0 to 1

[south creek]

What's your blend mode?

[white marsh]

Blend SrcAlpha OneMinusSrcAlpha

[south creek]

Is alpha:fade part of your surf pragma?

[white marsh]

Uh no, i guess that is the problem then

There we go, now it works. I didn't find any documentation on what optional parameters it could have. Is there any list somewhere?

[south creek]

https://docs.unity3d.com/Manual/SL-SurfaceShaders.html?_ga=2.28594620.1678047054.1643056457-1698399620.1632479260

[daring dew]

You can check out the "Liquid" Pass for more info Here : https://github.com/alelievr/HDRP-Custom-Passes

[white marsh]

thanks

[burnt wigeon]

Wondering. Does anyone have a shader to enable HDRP/URP decals to project on a transparent mesh?

I dont even know where to start looking to get this to work

[burnt wigeon]

To be more precise, I dont need to rely on the decal feature I am just looking for a way to have blow shadows on URP/HDRP on a transparent surface

[burnt wigeon]

As a side note, it works on Built in so I am scratching my head a bit

[nimble solstice]

Hi is there a keyword or some such directive to make shaders calculate AO?

[lean lotus]

So it turns out that Vector4 and float4 dont have enough precision(missing by 2 digits max) for a good conversion from 4 Uint32's to Vector4/Float4
is there something else I could use in a struct and easily pass to a compute shader that will have the extra precision that I need?

[shadow locust]

Make your own struct, no?

[lean lotus]

It’s a list<struct> rn

[shadow locust]

public struct Vector4UInt {
  public uint x, y, z, w;
}```

[lean lotus]

The struct is 5 float4’s

[shadow locust]

What struct

[lean lotus]

It needs to be uploaded to a computer shader via a structured buffer
Public List<NAME> NAME2;
Public struct NAME {
Public Vector4 node_0;
Public Vector4 node_1;
Public Vector4 node_2;
Public Vector4 node_3;
Public Vector4 node_4;
}
Sorry for formatting on phone now

This gets uploaded via a structured buffer to a compute shader with the same struct, but with float4’s instead of vector4’s, and it’s formatted this way to reduce memory things or something that apparently optimized fetches or something

But turns out the floats the vectors are composed of are not precise enough, so I needed full uint’s but unity c# doesn’t seem to have uint4’s I could use instead

[shadow locust]

Right that's why I'm saying make your own struct

so instead of 5 Vector4s

[shadow locust]

you make a struct like this

And have 5 of these in your NAME struct

[lean lotus]

Oh I see

I could but doesn’t unity not like nested structs?

[shadow locust]

Unity is barely even involved at that point

but no, unity has no problem with nested structs

[lean lotus]

Oh ok cool

Then yeah I’ll try that thx

[steady lintel]

Anyone know any good starting points for making a water shader in Unity’s Built-in pipeline? All I see are tutorials for URP or HDRP.

[amber saffron]

You can use shadergraph with built-in in 2021.2 😉

[steady lintel]

Aight sick thank you

[stiff tapir]

So, I've got a BRP Shader I wrote

It does a number of things, but what's important is that it renders a tex2d with screen coordinates

No matter where you look at it from, the texture is always facing you, simple simple

However this shader was written with VR Chat in mind

As in, a lot of people looking at this shader are going to be wearing headsets

Their view of the world is Stereo

I can use a texture space of IN.screenPos.xy / IN.screenPos.w when there's only one camera, but once you throw Stereo vision into the mix, one way or another I need to apply a correction to the texture coordinates to shift them left and right an appropriate amount based on which eye is viewing them

I've been made aware of unity_StereoEyeIndex, which is great, but I don't know how to properly calculate the amount the coordinates need to be shifted based on that information

[toxic fable]

Shader beginner here - Is there a way to only render pixels lit by a certain light source?

[regal stag]

@stiff tapir I'm not familiar with writing shaders for VR Chat (and not very familiar with VR in general), but I would assume they use single-pass instanced rendering if the result isn't looking as expected. There's basically just a bunch of macros that need to be added to custom shaders.
See https://docs.unity3d.com/Manual/SinglePassInstancing.html (and maybe also https://docs.unity3d.com/2022.1/Documentation/Manual/gpu-instancing-shader.html)

[regal stag]

You can use alpha clipping (clip(x) function or if (x < 0) discard;) in the fragment shader to discard (not render) pixels. To determine whether they are lit though will vary based on render pipeline, whether it's forward/deferred, and what type of light it is (e.g. directional point, spot)

[toxic fable]

Thanks for taking the time to respond. I use URP with forward renderer and the light source is a point light

[stiff tapir]

Interesting. I'll look into it and continue testing, thanks.

[regal stag]

Okay cool, and by "certain light source" we're talking about just one point light, or all?

If it's just one, I'd create a C# script to pass the position and radius of the light into the shader/material.

[toxic fable]

Yes, it is only one light. I'm trying to figure out an implementation of a Fog of War system in 3D environment that would also consider verticality, unlike many other methods that only rely on planar representation of the line of sight.

Short demonstration: https://streamable.com/6k3ojk

I figured a light could simulate the spherical line of sight.

[regal stag]

Hmm I see. I guess you also need point light shadows then (would need to be in at least URP v11 / 2021.1 since older versions doesn't support them too)
I'm not sure if you'll be able to use the GetAdditionalLight function in URP's ShaderLibrary specifically as it uses a light-index which I don't think you can obtain. It's mostly designed so you loop though all lights. But looking through the functions in Lighting.hlsl (or RealtimeLighting.hlsl in v12+) and Shadows.hlsl (e.g. AdditionalLightRealtimeShadow) should help piece together how to calculate the additional light and shadow attenuations correctly.

Well, probably don't need the actual light attenuation. I'd still pass the light position and radius into the shader and compare that against the fragment position (both in world space). But you will need to look at Shadows.hlsl to figure out how to sample the shadowmap. e.g. https://github.com/Unity-Technologies/Graphics/blob/c1d9dc44b25e9c192c9c3f190021a74da9cabcf5/com.unity.render-pipelines.universal/ShaderLibrary/Shadows.hlsl#L311

[toxic fable]

Thank you for the suggestions, I'll look into this. I'm at the stage of figuring out the best possible solution for my usecase so any idea in the pool is a great help. If it wouldn't be of much bother for you, would you happen to have any other idea of how could this be implemented?

I mean, the light solution might not be the best performing, so I was wondering if there are other ways to achieve this effect.

I've been googling for two days and only found a solution involving depth cubemap. While I do understand the concept, I'm not sure how to actually implement it and given the fact that rendering a cubemap is rather expensive task, I'm not sure about this option either

[regal stag]

I'm not sure. I don't really understand the verticality here, as I would have assumed every layer above the player should be in fog. Which means you likely don't need a proper spherical line of sight, and might be able to just compare the y positions?
I guess unless an enemy is standing near/on the edge, then you might need to be able to see them? But might be able to handle something like that with raycasts. Idk, I haven't done much with fog of war before.

[clear elm]

Hello! I don't know about shaders enough and am having trouble converting a custom shader to single pass instanced for VR. I've done it before following this (https://docs.unity3d.com/Manual/SinglePassInstancing.html)
but this shader doesn't have the same methods and such: https://pastebin.com/VQHj0Uuc

Is there a node in graph that returns if a value is in between 2 floats?

[shadow locust]

https://docs.unity3d.com/Packages/com.unity.shadergraph@6.9/manual/Comparison-Node.html

[plush bane]

Well these I need 2 to check if float is in range

Any idea why this is OK in preview, but doesn't work in editor or runtime?

[shadow locust]

Yep, use two of them, with the AND node to combine the results: https://docs.unity3d.com/Packages/com.unity.shadergraph@6.9/manual/And-Node.html

[shadow locust]

screenshot is much too blurry to read

[plush bane]

Well this I think is most important part

The alpha test ain't working

Hmm, or object space ain't working

:/

[regal stag]

If it's based on position the range of values may not be what you expect. The sphere in previews doesn't use the same -0.5 to 0.5 range the default sphere mesh uses, for some reason.

[plush bane]

Preview seems to use -1 to 1. I multiplied the object space input by 2. So it should change from -0.5 to 0.5 to -1 to 1. But still ain't working 😦

[regal stag]

If anything you want to divide by 2, not multiply. But the previews range isn't really -1 to 1, iirc it's something like -0.65 to 0.65. It's a bit of an awkward/weird scale.

You could instead provide your Comparison nodes with a Float property (some put through Negate node) so you can control the value from the material. You'd want it set to 0.45 or something instead in this case.
Also instead of doing two comparisons per axis, you could also Absolute the position before splitting it. Then just need to check the positive side - Less than 0.5/float property.

[plush bane]

Mkay will try tomorrow, tnx

hello, i'm trying to figure out how to render the first pass of my shader into a sampler that i can use for the second, how do i do this? (using built in render pipeline)

[normal kelp]

hey a question about shader graph.
My friend has started a project in 2020.1.10f1 and I already have 2020.3.2f1 installed on my pc. if it's only the shader graph, would we still be able to collaborate or will I need to install 2020.1.10f1 as well

[shadow locust]

You need to both use the same version of Unity to effectively collaborate

You should Both upgrade to the latest LTS version ideally

[summer beacon]

On the latest version of unity hub, has the option to create a HDRP scene disappeared? The only version i can find is to create the HDRP Sample scene, not a blank new scene.

[shadow locust]

These are project templates, not scene templates

hdrp sample scene will give you an hdrp project

[summer beacon]

I remember there use to be a bunch of options you could tick like HDRP when creating a new scene

Is using the HDRP sample scene the only way to do that now or am i just blind?

[shadow locust]

Creating a new scene happens when you're in the editor with a project open

You are currently in the hub choosing a project template

[summer beacon]

Oh shit yeah i shouldn't say scene my bad, i mean project sorry

[shadow locust]

It seems like they may have renamed some of the project templates is all

[summer beacon]

Hmm im not too sure what to do

[grizzled bolt]

It seems your options are to choose the HDRP sample and make a blank scene in editor, or make a project with 3D core and install HDRP manually

Tbh just pick the HDRP sample, make a new scene in editor and ignore/delete the sample stuff if you don't need it

[plush bane]

Can't figure out what I am doing wrong with this simple XY color interpolation shader

[white marsh]

what is the best way to render a geometry shader above another geometry shader? (not using the transparent render que)

[swift loom]

Does o.worldPos = mul(unity_ObjectToWorld, v.vertex); actually contain a real .z value or is it only x and y and z contains something else?

i was also trying something like this to get the z value of the object being rendered but it seems to never trigger

if(baseWorldPos.z > 0.5){
    return fixed4(1,0,1,1);
}```

[white marsh]

i figured it out, i changed ztest and now it works, but it still renders some stuff infront of other geometry i dont want it to. so how do i stop this?

[plush bane]

How do I convert Object position to angles?

[torpid hull]

Hi, when including an emissive texture into my shader (standard PBR) i'm getting some weird artifacts in game. It’s like the emissive texture is bleeding into other areas of the UV tiles, so around the edges of my mesh I get a bright outline when veiweing from certain angles. These are static objects that share a texture with other objects. I’ve tried tweaking everything in PP, texture import settings, Map Map settings, Anti-Aliasing settings, camera settings, graphics settings, I’ve even tried increasing margin around my mesh UV tiles and whilst I can improve the issue it is still present. For now, the only way to solve this is to have a separate material set up for emissive areas of my mesh, but that means more draw calls which I really want to avoid. If anyone knows how to solve this, please let me know. Cheers

[white marsh]

ok so im having a problem where this fernel isnt working properly. here is the script im using. could it be im missing something in #pragma? since it seem like _WorldSpaceCameraPos isnt working but idk

[low lichen]

Fernel usually is added as emissive, not albedo. Is it intentional that you're putting it in o.Albedo?

[white marsh]

oh, ok ill try that then

that seems to have make it look right, but its not reacting to my camera still. the effect is only applied from where light is hitting

it looks correct from the opposite side but itsnt moving its static to the light

i se there is an option to use interpolateview maybe thats what i need?

o wait, it could be that the view dir is named something else in the surface shaders

[low lichen]

There's something wrong with how you're calculating the view direction. Surface shaders calculate view direction for you, you just have to add it to the Input struct:

struct Input {
    float3 viewDir;
}

[torpid hull]

Do you have a directional light lighting that side of the sphere?

[white marsh]

i didnt really get viewDir to work, i might be doing something wrong here

[white marsh]

yes

i did make sure to add it in the input struct btw

[torpid hull]

have you tried tunring off your lights

[white marsh]

if i use worldreflection it kind of works, but it reacts to how close i am to it

let me se

[low lichen]

No, just use IN.viewDir as V. V is supposed to be the view direction.

[white marsh]

seems to be the same even without the light

oh, ok. does it need to be normalized tho?

[low lichen]

And fresnel is just the dot product between the normal and view direction, nothing else.

viewDir should already be normalized by the surface shader

[white marsh]

oh oki

[white marsh]

ah, there it works, thankyu

[slim steppe]

Hi im using a cube with inverted normals for a (unrealistic)atmosphere shader but the shader looks different while you're inside the cube

This is a picture with the outside(bottom left) and the inside(top right)

[torpid sapphire]

Hey, I struggle a bit with english terms on this one, but what kind of shader terms should I be looking for. I want the effect to appear on the lens of the camera, like saliva on the cam or someone breathing on it, making some steam/fog on the lens. (The camera being the one of the game)

[shadow locust]

Condensation?

Water Droplets. Refraction. Blur. Gaussian blur.

[torpid sapphire]

Wow thank you, i'll try with these new words, makes more sense than mine 😆

[steady lintel]

Does anyone have any pointers for making a water shader with Unity's built-in render pipeline? Maybe with shader graph? I can't find any tutorials for it, all I can find are ones for URP and HDRP.

[steady lintel]

Like, for instance, this one by Brackeys: https://youtu.be/Vg0L9aCRWPE
It's a really good tutorial, but it seems like many of the things he does in it are outdated. (Mentions Lightweight Render pipeline, uses PBR Master in shader graph, etc.)
Are there any tutorials or pointers anyone could lend me that are like this that apply to my situation?

[plush bane]

Anybody know how can I use smooth step to smooth out a alpha map?

[dim yoke]

The main functionalities havent changed that much really. Lwrp=urp. Pbg master = lit shader graph. You can watch any of the up-to-date shader graph tutorial to get used to new shader graph and then do that shader from brackeys video. All the nodes should work exactly same way except the master node doesnt exist anymore (Albedo = Base Color, position = Position on the vertex section)

[plush bane]

In shader graph?

[long shadow]

Heya
So I am currently making a simple toon shader. I am following the steps in this video: https://youtu.be/GGTTHOpUQDE.
I have a problem with this

Basically, when I disconnect the Baked light part, everything just looks normal.

But when I plug it in...

Suddenly it becomes blue

What is the problem?

[plush bane]

Lot's of questions and no answers 😄

[long shadow]

Shaders are hard, actually

Before shader graph I can only imagine the suffering of dealing with a C like language

[plush bane]

Anybody know how to smooth out the borders (circle its just an example, it will be different forms)?

[long shadow]

How do you want to smooth out the borders?
Like, what do you want to achieve?

[long shadow]

I solved it, just created another sphere and put the same texture :/

[torpid sapphire]

@plush bane higher resolution texture or anti-aliasing might help you there

[plush bane]

@long shadow it an alpha map... so when it cuts the borders are edgy.. like bad or no AA :))

[plush bane]

Its procedural

It think I need some smoothering strategy in alpha generation, not after its generated..

[long shadow]

My little monke brain doesn't understand how to use an alpha map, sorry, I don't think I can help you

[plush bane]

For now it's 1 or 0.. so it cuts ugly 😄

[low lichen]

Look into using fwidth for anti aliasing.

[near karma]

Hi folks, I currently have a compute shader calculating the points on an orbit, and I dump those in a line renderer, but it's cut off since it's so huge that it doesn't fit in scene space. Is there a way I could render the line with a shader instead of a line renderer component? Would that solve my problem?

[bronze tree]

First time using shadergraph for sprites, and I'm having a problem where the sorting layer is not being used. Is there something you need to add to shadergraph for that to work?

[sudden crescent]

is there anyone that can help in a call with me my shader isn't working the way i want it to

[ionic current]

You know in photoshop or html/css, you can do a drop shadow? How would you do this on a sprite?

I'm considering making another spritesheet of the dropshadows, and putting it under the sprite, and using a "shadow" script to scale/offset it based on the Z or Y height.

But, if shader would be better, tell me about it! 🙂

[plush bane]

Any tips ideas, how to turn a box into 3d ring with shader graph? What I am currently trying works only on a plane.

Form wise

uff

[dim yoke]

sounds like usecase for ray marching

[plush bane]

Ouh no

[dim yoke]

@plush bane you can check these for better understanding of raymarching: https://www.youtube.com/watch?v=PGtv-dBi2wE and https://www.youtube.com/watch?v=S8AWd66hoCo . with these distance functions, you would be able to make the ring: https://www.iquilezles.org/www/articles/distfunctions/distfunctions.htm . because raymarching requires loops and stuff, it may not be very optimal to do using shader graph. you can use custom function node to add hlsl code in shader graph tho.

[plush bane]

I know very well what raymarching is and its way to expensive for what I need here 🙂

[dim yoke]

how would you do that then? you need to somehow get the intersection between the ring and and the ray coming from camera. for such complicated mesh, it would be very hard to get that intersection without ray marching. even ray/torus intersection is extremely complicated thing (http://blog.marcinchwedczuk.pl/ray-tracing-torus)

[dim yoke]

it depends on the case, but ray marching isn't very expensive usually (depends what you compare it with. even very complicated fractals with long for loops inside distance function can be rendered realtime using ray marching). can you explain bit more about why you want to do that and not using 3d mesh for example?

[plush bane]

Idk! That's why I am asking. Its probably not possible and I will create the mesh in Blender instead.

[plush bane]

RayMarching belongs to family of ray-tracing. So its heavy. Otherwise all engines would be using it for fotorealistic rendering 🙂

I'm my self working on a side project, a SDF raymarch renderer in compute shaders. So I know what I am talking about.

Raymarching a single primitive or generic fractal might still be ok for some showcase/demo, but if using in lots of places, it would just kill weaker hardware.

[slender forge]

Is there a fix to the tree creator optimized shaders?

[plucky jay]

Hi! I am having an (i hope) really simple begginer issue, but I am not finding any solution!

I am trying to make a shader that needs to tile an sprite, but somehow it is not working haha

I have set the tiling from "tiling and ofset" and it seems to work (is streching the image to the left) but instead of repeating the sprite on the other side, it shows it blank

[regal stag]

The wrap mode on the texture needs to be set to Repeat (rather than Clamp)

[dim yoke]

You have to set the Wrap Mode of texture to Repeat or make on the shader so it repeats the uv coordinate

[plucky jay]

thanks!!

haha

[dim yoke]

depends on how much is the mesh (the actual 3d model) covering pixels on the screen. on weaker devices id most likely not use ray marching either. if there's no specific reason to use ray marching over 3d model, its just better use 3d mesh. (I don't know any ways to get that kind of shape without ray marching)

[tardy warren]

Hi,

There is something in the deferred rendering path (Built-In Render Pipeline) that I can't understand, maybe somebody should be able to answer here. For a specific effect of the game I'm working on, I need to modify the final color based on a mask (for some reasons, I can't use Post Processing for this effect). I use the alpha channel of GBuffer2 which is not used by Unity to write into this mask. In the CalculateLight() function from the Internal-DeferredShading.shader file, I apply a filter to the return value based on this mask.
This works well, but I have trouble with emission that is not apply at this step. Does anybody could point me the shader that apply Emission in the Deferred Rendering Path ? Or is their a better entry point for modifying the output color in deferred ?

Thank you very much !

[muted ridge]

Does anyone know how I could construct a cubemap texture at runtime from 6 renderTextures.

[low lichen]

You can use Graphics.CopyTexture to copy from a 2D RenderTexture to a specific face of a cube RenderTexture. Do that for each face. The cube RenderTexture has to be the same or a compatible texture format and the resolutions have to match.

[coral walrus]

Hello (first post here 🙂 ), I have an issue sampling the depthtexture using URP on android. I can read it perfectly in editor (I checked the use DepthTexture option, in the urp settings asset ), but on device it outputs only white on my S6 and S7 (I'm using frac(sceneEyeDepth*10) to make sure I have some data in it) . Any clues would be more than welcome 🙂

const float rawDepth = SampleSceneDepth(IN.screenPos.xy / IN.screenPos.w);
const float sceneEyeDepth = LinearEyeDepth(rawDepth, _ZBufferParams);

[hearty obsidian]

do both sides of a branch typically execute or can I use branching to optimize expensive possibly-temporarily-unrequired operations

[sudden crescent]

can anyone help me with shaders

[dim yoke]

What you mean by branch? Branch node on shader graph?

[hearty obsidian]

@dim yoke yes sir

[dim yoke]

Afaik it executes always both sides and combines those without dynamic branching.

[hearty obsidian]

@dim yoke Ah, so no performance optimizations can be performed this way. This is unfortunate. Thank you for the answer

[dim yoke]

Dynamic branching on shaders is usually not better, sometimes much worse

[hearty obsidian]

I'm lost. Isn't the branch node "dynamic" in the sense that the predicate is evaluated at runtime and will branch according to the value?

[plush bane]

When using transparent + render face = both + Depth test = always I kind of get the result I want. The shader is always on top, visible from both sides and does alpha clipping. But then when look from sides it starts glitch and blend together. I wonder if there is any strategy to fix this?

Actual

What I want

2nd is with front face only. Its not visible from other side

[dim yoke]

Yes it is but it doesnt need to choose between two branches. It always executes both sides and uses math to discard the wrong one.

[plush bane]

Maybe cloning the object.. one render with front face, other with back 😄

[hearty obsidian]

@dim yoke HAH! I get it, this makes sense. Thank you

[torpid sapphire]

Hey, it's me again, looking for some insights as to what terms I should be looking for : I want to know how I could achieve an effect where an object would pass in some tree branches and the leaves would move according to the mesh passing through it.

Example : a gorilla is hidden in a thick bushes and exits it.

I'd like to have a natural movement (as much as possible lol) of the leaves and the meshes. What techniques would that be ?

Thank you 🙂

[sudden crescent]

can anyone help me i am begging

[echo flare]

Why do urp unlit shader graphs cast shadows?

[echo flare]

vertex displacement on the mesh with adjustable strength triggered by a collision from a collider attached to both the gorilla and the bushes. Vertex displacement is actually fairly easy https://learn.unity.com/tutorial/shader-graph-vertex-displacement

[normal kelp]

make sense, thanks for the reply. much appreciated

[lean lotus]

Is there something like Cudas block in Hlsl compute shaders? Trying to convert a complicated cuda thing into unity but I’m struggling
If it’s even possible to convert this shader, not so sure because I think the thread count available in unity at once is less isn’t it?

[sudden crescent]

@echo flare i was wondering if you can help me fix my shader i dont understand what is wrong

[echo flare]

what is your issue

[sudden crescent]

well im trying to add a gradient to a mesh and for some reason the color is pink

iv tried to fix it but i can't find a solution

[echo flare]

what @sudden crescent what pipeline are you using? standard, universal, or HD?

[sudden crescent]

i was trying to use universal

[echo flare]

ok, I'm pretty sure you are attempting to use a standard shader within URP. URP only deals with vertex/frag shaders which you create through the shader graph ui. You either need to upgrade your materials or create new ones https://answers.unity.com/questions/1519382/textures-and-materials-turn-pink-after-installing.html

@sudden crescent try changing the shader of your material to universal render pipeline -> unlit

[sudden crescent]

it still isnt working

is it possible to go into a vc

[sudden crescent]

@echo flare

[patent lily]

hi, Is there any tools that can transfer build in custom shader to urp ?

[torpid sapphire]

@echo flare awesome i'll have a look at this thank you. Never heard about collider interacting with shaders but this makes so much sense. Collision hit point is fed to the shader to react accordingly 💡

And i guess in most case a generic vertex displacement triggered by the collision is enough ! Regardless of collision position

[upbeat nimbus]

https://pastebin.com/f5DgV1XA This shader creates an outline and I'd like to make it thicker, what do I change?

[snow harness]

Hey guys! Im recreating pong right now and I'm trying to have a light that follows the ball around while on Update changing its color to that of the ball. Problem is ball is using a simple shader that changes it's hue all the time. I don't really know how to solve this, and to be fully honest, I'm not even sure how to google this one lol. Anyone knows how to take hue out of a shader into a normal script?
I've tried using Material but it screams at me for saying ball is not using any.

[stark musk]

anybody have resources for how you can achieve ambient occlusion in an unlit urp shadergraph?

[dim yoke]

if you mean regular unlit shader, i don't think that's possible (atleast easily). ambient occlusion is usually done in post processing because it requires multiple samples from environment to see how dark certain pixel should be.

[stark musk]

any way to apply that to an unlit shader then?

[dim yoke]

I'm not quite getting what you want to do and why

so are you trying to add ambient occlusion post processing effect and it doesn't affect the unlit shader graph material or do you want to make unlit shader that adds ambient occlusion into only that shader without using post processing?

for some reason unlit shader graph seems to be lacking DepthNormal pass. you can check this (they suggest some potential fixes there but nothing very good it seems): https://forum.unity.com/threads/adding-depthnormals-pass-to-unlit-urp-shadergraph-feedback-sg-devs.1060646/

[languid zodiac]

Hi. Is there in urp global variable which contains shadow distance?

[blissful atlas]

does anyone know if there's a way to get the internal camera/view/projection matrix from the GPU in GUI drawing contexts?

I have a strange issue where it seems to silently change under the hood, which messes up some drawing I'm doing with shaders that rely on the matrix being, uh, reasonable

GUI.matrix is consistent, so that's not the one changing

and I can't seem to find a way to get the current matrix in the GL class

basically, when I don't have the scene view open, my rendering looks like this

but when it is open, it looks like this

the shaders I use rely on the view and projection matrix to determine their size in pixels on screen, so somehow the scene view does something to some GUI-related view/projection matrix somewhere for this to happen, but I don't know how to debug it since there's no frame debugger for editor plugins

[lost idol]

does unity come with any working shaders that have height maps? seems like they're outdated for some reason

[trail geyser]

Is shader graph's dynamic vector type available in URP? can't find it.. using 12.1.3
https://docs.unity3d.com/Packages/com.unity.shadergraph@12.0/manual/Data-Types.html

[regal stag]

The dynamic vector is used for ports on other nodes, you can't create a property with that type.

[trail geyser]

Was trying to create a subgraph.. guess I'll have to create 3 more copies for each type 😅

Thank you

[amber saffron]

Or just make a single subgraph with a vector4.
Theorically, the compiler should optimize this afterwards if you only use 1 2 or 3 dimensions

[lean lotus]

Are there any resources that go beyond basic getting started with hlsl compute shaders? I’m trying to do stuff with compute shaders, but all the resources I can find don’t tend to cover what I need or go deep enough
(Aka, multiple kernels in one shader, groupshared and how best to do that, and most importantly, structured buffers that gets generated by one kernel and used by another)
Also I think I remember there being a way of feeding a structured buffer directly from one kernel to another kernel without passing it back to the cpu first, am I misremembering?

[drifting sail]

Hi, I'm having a problem with shader. I'm creating 2D game. And I have a problem with sprites. When they flip (Cause of turning left or right), they become invisible from the other side when I use material on them to make lights work on it. So i downloaded some free doublesided shaders, but problem is the texture doesn't go on the other side. just color. any help please?

[drowsy linden]

Turn off back face culling, somehow. Or flip the texture rather than flipping the object around

[balmy thicket]

Anyone know if it's possible to create a wear shader that highlights "sharp" parts of meshes?

Pic for reference

Scratch that, seems impossible/infeasible from perusing the forums

[wild dirge]

Hi I'ts my first time using shaders, I'm using Unity 2020.3.21 and for some reason when I add a texture I get this weird glitch

that texture is a transparent PNG, but for some reason, it looks very weird

[torpid sapphire]

@wild dirge I believe the preview displays your PNG colors regardless of the alpha value. There might be these weird color in your png transparent pixels for some reasons. If you use alpha correctly in your shaders, the final display shouldn't display these colors, as they will be transparents.

Also make sure to toggle in the texture import menu that this texture as Alpha (Input texture alpha) and that alpha is transparency

[wild dirge]

Thanks @torpid sapphire I get it

[lean lotus]

If I put 3 compute shaders inside 1 shader file as different kernels, do they contribute to eachothers register count, or do they each have their own register count(and thus how many threads/warps they can launch)?

[wild dirge]

I'm trying to make a shader that adds a pink outline around a texture. But for some reason the final result looks really bad

That pink isn't exactly the pink I choosed at all. Also if I pick the black color, it doesn't even show up...

[regal stag]

Use a Lerp node, with Texture RGBA in A, Magenta Color node in B, Subtract in T

May also want to Saturate the Subtract output, to clamp between 0 and 1 to remove any negative values

[wild dirge]

I don't really get how to do that :( (it's my first time using shaders)

[regal stag]

Subtract node -> Saturate node -> into T of Lerp

[wild dirge]

Like this?

It looks much better but I still have a weird outline around the object

[regal stag]

Put the magenta Color node directly into the B input, no need to multiply

[wild dirge]

starting to look better, thank you so much!

[steel notch]

Is there any form of standardized "Vertex Color Maps" for meshes? I have a series of values that are supposed to be mapped to each vertex and then converted to come color. I was wondering if there was any standardized approach for this.

[balmy thicket]

I'm working on a liquid shader and wanted to add some wobble to the top, however I have some issues as you can see with the bottom backface being visible and showing something on the inside of the cylinder (the top) that would be a projection of what's shown at the bottom

Anyone ever done something like this? Seems quite tricky

[meager pelican]

I don't have a direct answer to your matrix question, unfortunately.
However, it occurs to me that if debugging is a challenge, you can try using the manufacturer's tool-set for your GPU. Both AMD and NVidia have dedicated debugging tools that even let you edit and play with shaders, benchmark, etc. They're a P.I.T.A to install and get going, so you'd have to bite the bullet. But you can get all sorts of neat info, and even edit the shader, IIRC. Full disclaimer, I've not tried it with an editor plugin.

[blissful atlas]

I got it fixed in the end!

[remote wigeon]

Would there happen to be any good place to get materials for URP online? I know asking free is unrealistic, but I’m just curious as to what’s out there

[steel notch]

Are you unable to give Arrays (like an Array of ints) to Shadergraph or shaders in general?

[simple violet]

no

you could technically have a bunch of int properties but that's wasteful

you need to think differently when it comes to shaders

[echo flare]

Have you looked at the asset store? Lots of free stuff there

your graph settings need to be set to Transparent and set the alpha clip

[sacred trellis]

why is my scene stuck with baked textures even though i got rid of the area lights and regenerated the scene (also got rid of static and it's still like this)?

also the scene for some reason shows it without the baked lighting only when i play:

[torpid sapphire]

@grand jolt You can use Opaque render type. But you must use alpha clipping.
If I were you I would do this :

Plug the fill color directly into base color.
Use your comparaison that tells you if the current frag (pixel) is in the fill zone or the empty zone to set the Alpha of your frag.
If it is in the fill zone, put alpha to 1. if it is in the empty zone, put alpha to 0
Set Alpha clipping to 0.5 or anything between 0 and 1 (not 1)

This way, you tell unity to discard the frag (clip it) if it is in the empty zone. It will not longer render.

In short : The color is always the fill color, but you may or may not render the pixels depending on wether it belongs to the fill zone or the empty zone.

[shadow locust]

Shaders in general yes, see computebuffer/graphicsbuffer/StructuredBuffer

Shader graph doesn't have support for it yet

[steel notch]

What's the reasoning for that?

[little quarry]

Probably that it's not implemented

[regal stag]

Unity shaders support some arrays (float and vector/float4), e.g. https://www.alanzucconi.com/2016/10/24/arrays-shaders-unity-5-4/
As PraetorBlue mentioned, there's also compute buffers.

I've used both arrays and StructuredBuffer before in SG through the Custom Function node, using File mode (acts like an #include) to declare things outside function scope.

[trail geyser]

Thanks I'll take a look at it!

[meager pelican]

You can, but they have to be fixed sized arrays. The compiler has to know the size at compile time.
You don't use Unity's Inspector Properties for it though, but you can set it in script.

[dry granite]

Hello everyone! I'm new to unity and writing shader code, but I want to learn and my end goal would be to create something similar to this https://www.reddit.com/r/Unity3D/comments/qsg2ca/custom_terrain_stamping/

It's using a compute shader

I would love to hear an opinion on how complex this seems to you, and if you've got some resources to where I could learn more about compute shaders, specifically about deforming a standard unity terrain with a compute shader

[simple violet]

Probably need years of experience to replicate and understand everything going on

There's definitely some triplanar shading going on

[dry granite]

I only want to replicate the part which edits the terrain topology

[deft root]

So i have this shader, I was following this tutorial and right now its just blank white

its meant to look like this

[upbeat horizon]

quick question

I have this polygon texture being made in shader graph

and I want to remove the black background

how can I do that?

[little quarry]

Remove?

Like make it transparent?

[austere dew]

Does anybody else notice shader graph tends to do different stuff per triangle of a mesh? I've ran into this problem many times over various graphs on various meshes, and it sure is annoying.

For example: here unity decided to use the normals on the top left triangle, but just gave up on the rest.

[grand jolt]

This might be a stupid question, but how do i add new materials?

[austere dew]

Right click in "Project" window, Create > Material.

[grand jolt]

ty

will this still be locked?

[austere dew]

Drag your newly created material to that inspector window.

[grand jolt]

ok

[austere dew]

I only ever have shadergraph issues per triangle with the normal.

[grand jolt]

it does not let me drag it

🚫 <---- My mouse turns in to that symbol while im hovering over with the material

[austere dew]

Are you doing this to a game object in the scene? Can you show all the components in the inspector?

minimize the components for a picture.

[dim yoke]

Im pretty sure this is not issue in shader graph… shaders only interpolate the information they get from vertex shader. Your 3d model may be incorrect in some way (either uv or normal changes between those triangles). You could also show the shader graph youre using so it would be easier to see if something is incorrect there

[tiny wharf]

Maybe a silly question (also apologies for interrupting the current convo 🙏 )

Say I want to change the color of a sprite to colorA, but then change it to colorB which slowly fades back to the colorA, how would I go about that? I'm using the same material and shader to change the tint at the moment and that doesn't have the desired results :)

It doesn't look like there's currently a way to attach two materials to a sprite renderer, so my options seem to be

• remove the smooth fade
• create a new object with that sprite and render it directly overtop of the existing sprite and slowly fade it out instead

I'd prefer to keep the fade, but wanted to make sure there wasn't a better way to accomplish this with existing tools :)

For example, let's say there's a square that can be colored differently via the shader. If it takes damage, I want it to flash white and slowly fade that white's alpha value to zero but keep the current color of the square.

[fleet flint]

Why isn't my main camera capturing anything?

Am I missing something?

[lean lotus]

What can make groupshared memory in a compute shader extremely laggy?
trying to use it to speed up a stack for tracing

[shadow locust]

where's your inspector window?

What's the culling mask on the camera?

How far is it from the cube and what's the far clipping plane?

[upper sphinx]

you can select the layers that you want the camera to show. if there are for example gameobjects with the layer name “layer 1” and you remove layer 1 from the culling mask, the camera won’t render them

[upper sphinx]

Clipping plane I don’t know :/

Hey I have a problem. I’m trying to access shader properties from script but it doesnt work. I need a vector3 from a shader graph shader so I coded

playerMaterial.GetVector3(“name of the material”) = new Vector(…);

but I get an error saying that Material does not contain a definition for Vector3

[neat hamlet]

its material.GetVector, not vector3

[regal stag]

Also the string should be a property name, not the "name of the material". And not sure why you're trying to assign (the = new Vector(...); part) to a function...
To clarify too, this is only to obtain a value from the material (either set in inspector or set previously through material.SetVector). You can't set values in the shader and obtain it on the C# side.

[shadow locust]

I know what they are I was specifically asking that person what theirs was set to

[upper sphinx]

I tried all GetVector, SetVector, nothing worked :/ I’ll look at it tomorrow again

thanks yall

[regal stag]

I imagine you could probably do this in a C# script by lerping between colours and changing the spriteRenderer.color. That way it would also work with default sprite shaders (or any shader that renders with vertex colors) rather than needing to create something custom.

[upper sphinx]

I’m a noob at coding stuff so I just use animations for stuff like that. you can animate a materials properties

[vagrant pumice]

Quick question: If I have an object that's made up of flat colored faces, is it more efficient to have multiple materials, one for each color with no texture, or a texture with the colors mapped out on one material?

[tame topaz]

A texture would be, especially if you could reuse it for multiple objects.

Just add all your colours to a grid and align the UVs to the proper colour.

[vagrant pumice]

Oh, that's smart

That'll be the way to go for all my pure flat shaded stuff

[tiny wharf]

Ah, I tried something similar to that earlier, but didn't get what I wanted. I'll keep trying though.

[tiny wharf]

I hadn't even thought of that tbh 🤔

[lost kernel]

Is it really that hard ... i want a unlit shader that receives shadows , just a color input and thats it , all examples i find seem to don't work anymore

[meager pelican]

Like Cyan said, Lerp should work.
You'd lerp between the actual-color and White (or whatever highlight color) by passing in a value to your custom sprite shader.
The value is 0 to 1 where 0 would be, say, the normal color and 1 would be fully highlighted (single color). Then it's a result of
float4 finalColor = lerp(pixelColor, highlightColor, amtLit);
So an amtLit of .5 would be 1/2 way between the pixel color and the highlight color (white in your example).

You'd set that amtLit in script per frame.

[tiny wharf]

Thanks for help! :)

I just got it a bit ago using Color.Lerp correctly. I misunderstood how it worked before :)

Thanks a ton for the help 🙏

[fleet flint]

inspector window was locked to a material, culling mask was set to everything, clipping planes were set to 0.01 and 1000 (near/far respectively)

[fleet flint]

I got it working by setting the camera's background to solid color for some reason

[grand jolt]

HOW DO I ADD AN OBJECCT

IN 2022

UNITY

[eager folio]

Is there a straightforward way of having unity not compile every single unused shader and shader variant when building?

[mental bone]

Read this https://blog.unity.com/technology/stripping-scriptable-shader-variants

[steep creek]

how can i find the dot product of a normal and world up. I can't find a way to get a world up direction in a shader.

[regal stag]

World up is just (0, 1, 0)

[steep creek]

how do i create a new float3 tho. like float3 worldUp = what goes here?

i never made one with just values

[regal stag]

float3 worldUp = float3(0,1,0);
Though you might not even need a dot product. Just using worldNormal.y might be the same result.

[steep creek]

i need an angle between up and normal so if the angle is above something i can apply the stone material and not a grass one. I'm making a terrain color shader

[regal stag]

Sure, but dot(worldNormal, float3(0,1,0)) should be equal to worldNormal.y so could just use that. Both return 1 for faces facing upwards (assuming normal is normalised) and 0 for faces facing perpendicular (also -1 if faces were facing downwards but that's unlikely with terrain, unless it's a custom one that supports overhangs)

[steep creek]

                    {``` this for some reason doesn't work literally everything is rock

[regal stag]

Try with a value of 0.5 instead of 0.

[steep creek]

it's 0.4 idk why i wrote 0

[regal stag]

Maybe try with other values. 0.8? Otherwise check how worldNormal is calculated.

[steep creek]

i tried 0.8 and it seems to be inverted

i found this little patch of grass on a hill

yep i changed > to < and it works fine now

thx for help

shaders are a bit hard for me to understand right now

[stray osprey]

Hello there, again!
I'm using MinionsArt's compute grass shader (https://www.patreon.com/posts/54164790) and I have big framerate drops using compute shaders.
I've already talked about this with the shader creator, but this problem is weird because we have almost same GPU (1050 and 1050ti) while getting completely different result, where Joyce can have 100k grass with no problem and I get drops from 120 fps to 50-60 with only 17k grass (and 20fps on 60k grass). I get more than 4ms of delay on "DrawProcedural".
The difference is that MinionsArt uses built-in rp, while I use URP.
I've searched up if there's something up with URP compute shaders, but I found nothing on this topic.
I understand that URP might be more complex on rendering than built-in, but is the difference that bad? Or could the problem be within the compute shader itself?

[eager folio]

I did; the links on it are dead and the information somewhat outdated. It turns out that the actual solution was to go into the graphics settings and clear the preloaded shaders out.

[vapid heart]

Hello. I was configuring a simple skybox shader. I assigned to Side picture the same texture, but it won't be tiling:

And the joint line is visible too

how do I improve that? I may kinda stop worrying by now, ||it's a free project for itch.io||, but... I am really curious

[vapid heart]

it gets noticeable when I push exposure

[frozen lava]

hey all, im trying to get a vertex color shader working (any) but for some reason they all come out pink, im using mesh.colors and they show up using a particle shader - problem is I need shadows also. Any ideas what the pink issue might be? thanks

scratch that, just tried in shadergraph and worked first time lol

[dim yoke]

do you use any post processing effects like ambient occlusion?

also because the 6 sided uses cube as the mesh, it will not look cylindrical anyways if those textures doesn't take that into account

not sure why that darker line on the corners appears tho

[vapid heart]

Here are my backgrounds

I use project with default settings

[meager pelican]

The 4ms drawprocedural delay wouldn't be from the compute shader part, that would be from a procedural mesh shader call, right? The compute would be from the dispatch call.

[stray osprey]

I guess you're right? I just meant that it's from this compute system. I'm not very good with defining it, don't know much about written shaders like this

MinionsArt is working on an update for this system but I'm not sure if it'll help much with my performance issue so I wanted to try to get help here

[meager pelican]

I'm saying it might NOT be from the "compute system", but rather the drawing side of things. I cannot tell from here.
Might be the compute shader, if the draw call is waiting on the compute stage to finish. Not sure.
Or it may be that the compute shader is fast enough, but the draw part in URP is having some...issues...for lack of a better term.

[meager pelican]

The other ways to debug it, besides what you're probably doing:
use PIX
use your GPU vendor's graphics analysis tools, they can tell you down to the detail where the performance hit is. For example, too many vector registers used to have enough wave fronts to make it performant.

Cyan ✨ (@Cyanilux)

@hammyxhammy That's true, but the particle trails also have a Tile texture option, so the UVs will already tile!

I have a head and tail of an arrow and would like to extend only the straight line in the center

Also I'm using it in a line renderer

@regal stag was able to make it a single line :D. Still stuck with adding a footer though

nevermind, I guess I can skip the footer since the line renderer draws from the character's point

thank you Cyan 😄

the arrow head is the other way round 😦

I would like to have it at the top since thats my end point

[regal stag]

Swapping the order of the positions would probably work

[ivory crest]

@regal stag duh! ofcourse! thank you

[plush bane]

Hey I still don't understand why I am getting those weird results with Transparent + Alpha + Both + Auto + Always ?!

Its like conflicting with it self

[vocal narwhal]

Using transparency, within a single mesh the triangles are rendered one by one, and are not sorted by depth. This can cause issues of overlapping geometry within a single object when viewed from some directions.

sometimes strategically separating portions of the mesh can result in a consistent viewing experience where each of the new object's centers will be correctly sorted. But really, the best solution is just to use opaque, if you need transparency use alpha cutout or dithering with cutout

[plush bane]

opaque with alpha clipping produces same problem... i think its the mix with both faces and always depth test

[vocal narwhal]

That might have the same issue as transparency, yeah

[plush bane]

So what do I do? I need my object to be always on top (it's kind of a handle/gizmo) and viewed from both directios :/ + alpha

[tame peak]

Hello, I've got a complicated shader (Super Fast Grass) that I want to modify to only draw within a certain distance, though I have little shader writing experience and the shader itself seems to be generated from Amplify Shader. Would adding a clip after a certain amount of distance act the same as, say the camera clipping planes, to help with performance?

[vocal narwhal]

Just to be sure, when it was Alpha cutout it was marked as opaque right?

[plush bane]

Yes with Opaque I use Alpha Clipping

[vocal narwhal]

I'm not sure as to the best fix as this sort of thing can be very confusing. I can only think of spitting the object up into inner and outer faces and forcing the render order.
I have to sleep, so I hope you sort it out or someone else knows!

[plush bane]

Ok, tnx bro

[plush bane]

The allways option just works bad.. Is there another way to set depth?

Uh, getting nice results when playing with queue

[lean lotus]

Hey so Im having an issue with compute shaders
basically, im using 1 kernel to write ray directions and origins to a rwstructured buffer that I then use in another kernel
Now if I display the ray directions from the first kernel, immediately after writing it to the RWbuffer as a texture, its fine
but if I then read it in the second kernel, and display that instead, I get this, why is that left side always like that?
Btw the code im using to index into the RW buffer is this:

    uint width, height;
    Result.GetDimensions(width, height);
    int index = id.x + id.y * width;

where id is SV_DispatchThreadID, and Result is the texture that i am writing to as output
and the ComputeBuffer when created on the cpu side has a length of Screen_width * Screen_height

[lean lotus]

also why is groupshared memory seemingly slower to access then say, memory declared in a function like this

[dim hemlock]

Hey guys. Is there a reason why i cant connect IsFrontFaced as a condition to the vertex normal parameter?

[regal stag]

It can only be used in the fragment stage as it's calculated during the rasterisation step between the two stages.

[dim hemlock]

ahh I see. Thank You 🙂 @regal stag

[digital vector]

Ayo guys; So i am currently planning to move my grass-geometry shader to a compute shader (as most of the calculations are the exact same every time), but now i'm wondering what would be more efficient:

• Should i store the vertex and triangle data in a mesh/mesh filter after computing and render it using the mesh renderer
• or should i use compute buffers with Graphics.DrawProceduralIndirect (i think this is the right method? i won't draw the mesh more than once per frame)

[near current]

Hya. I havent done any shader writing in a Long time, at least 3 years. Im not using the Built-in Render Pipeline atm, and need to write a shader for a 3d Mesh object that is Unlit, and always renders in front of meshes in a certain layer

Where should I look to do this? What terms should I google? I found stuff about using a Stencil, but that seems to be a ShaderLab command, and I dont think I'm familiar with that

Should I look into the Shaderlab thing? Or is there a way to do it in HLSL? that's what I used a few years back / am used to

[digital vector]

If you are using URP, then Cyans guides are a great place to start with URP HLSL and Shaderlab https://www.cyanilux.com/contents/

At least they helped me a ton in that matter!

Have you added built-in as a target for you shader ?

It's probably be difficult due to the way sprites batch (combined meshes). Might be easier to just rotate the GameObject

They are a part of the shader. Basically a Dot Product between the sunDirection & normalized UV.xyz or Position node (they are the same thing in skybox shaders). Then smoothstep / remapped to make it smaller. Can obtain the sunDirection through a custom function returning GetMainLight().direction.
The moon calculation is more complicated (the thread contains some info about it), but it's an empty GameObject with a script to send the direction in, e.g. via material.SetVector("_MoonDir", transform.forward).

[silver sparrow]

sounds confusing asf ngl, are you gonna write an article about it on your website?

[regal stag]

If you want transparency you should set the graph type to Transparent under the Graph Settings, and connect your noise to the Alpha port on the master stack. You don't need to connect it to colour unless you want the fog to also darken in colour.

[regal stag]

It's been on my todo list but unsure if I'll get around to it. There are also some other tutorials for procedural skybox shaders out there already that might help :

btw, the sunDirection you're talking about, is it the Main Light node?

[regal stag]

Probably yeah

[silver sparrow]

ohhh

[odd silo]

anyone?

[wild thorn]

You could use this as reference:

• https://github.com/TwoTailsGames/Unity-Built-in-Shaders

But they're not always that easily to read. Besides that, I bet there are some tutorials out there if you google around 🙂

[regal stag]

Depends on the pipeline. For HDRP it's not really recommended to write shaders from code. If you're using URP I've got an article : https://www.cyanilux.com/tutorials/urp-shader-code/
For built-in there's plenty of shader code tutorials online, I've got a few listed on my resources page under sites/blogs and intro to shaders headings (https://www.cyanilux.com/resources/)

[odd silo]

thank you ill try to understand that lol

[odd silo]

wow you actually did a really good job with the article im impressed

[dusk cobalt]

can anyone help me make procedural noise or something shader like this?

[odd silo]

you can generate it with c# and then pass it as a texture2d

[cosmic prairie]

Even better, use blender nodes, they already support this kind of stuff 😄

Making a shader to resemble something that does not change is a huge waste, try to avoid it

[dusk cobalt]

How i can export blender nodes to Unity?

[steel notch]

Is there any way to set the value of a Gradient in Shader Graph from C# ?

[cloud dust]

I'm not seeing Built-In as an option for active target in the shader, do I need to do something else to get it to show up? Sorry if this is a noobish question with an easy fix, just getting the hang of shaders now

[regal stag]

You may need to update to Unity 2021.2 if you aren't in that already. Previous versions don't support Shader Graph in built-in RP.

[regal stag]

No, Gradient values get hard-coded in the generated shader.
If you need to be able to edit values from the inspector, use Color properties and Lerps, or store the gradient as a Texture and use the Sample Texture 2D node instead.

[fervent tinsel]

they added built-in target in 2021.2, yes

worth nothing that while that exists, it will not support instancing (unless this has changed since)

meaning you can't make VR single pass instanced compatible shaders for built-in with SG

or use shader instancing otherwise

[steel notch]

well that sucks

[regal stag]

You can't convert blender nodes to a Unity shader. But I imagine you can bake the material to a texture. I'm not very familiar with it, but after a quick google this might help : https://www.youtube.com/watch?v=LLQFopN--LY

[steel notch]

how big would you suggest the texture to be?

[regal stag]

Probably depends on the gradient. Maybe 256x1 🤷

[cosmic vector]

So I have an infinite terrain system I'm working on right now and I'm dividing the terrain into biomes using the shader graph voronoi node, Is there any way in c# for me to tell which biome I'm looking at? any help is much appreciated!

heres what its looking like right now

[regal stag]

If you need to know the biomes on the C# side it might make sense to just do the voronoi calculations there instead, then send it into the shader through a texture / vertex colours (or I guess as long as the calculation is the same can continue using the voronoi node too)
Can see the code SG uses here : https://docs.unity3d.com/Packages/com.unity.shadergraph@12.0/manual/Voronoi-Node.html

[cosmic vector]

I'll do this, thank you

[cosmic vector]

so I've been converting it to c# and i think I've just about got everything besides this line UV = frac(sin(mul(UV, m)) * 46839.32); do you know how I could write it?

[slim tulip]

Greetings, is it possible to make a part of the sprite shader unlit?
Working with the lit sprites, and outline messes everything up...

[knotty yarrow]

anyone know why is my scene color nodes in shader graph not working

im using the built-in render pipeline shader graph

ive been looking for solutions

but i only found the solutions for urp and hdrp

[amber saffron]

It's highly possible that this node is not supported (yet ?) in BiRP

[regal stag]

I think it would be equivalent to

Vector2 res;
res.x = 15.27f * UV.x + 47.63f * UV.y;
res.y = 99.41f * UV.x + 89.98f * UV.y;

res.x = Mathf.Sin(res.x) * 46839.32f;
res.y = Mathf.Sin(res.y) * 46839.32f;

res.x = res.x - (int)res.x;
res.y = res.y - (int)res.y;

[regal stag]

I don't typically work with sprites but it wasn't possible in Shader Graph last time I checked (assuming that's what you're using). I ended up duplicating the sprite and using an separate material w/ sprite unlit shader just for the outline.
May not be the best solution if you need many objects outlined though. Could try generating code from the graph and editing that.

[slim tulip]

Since I use outline as "Select unit" logic, yeah, think I can duplicate the object without significant performance drop, thanks!

How to access "Color" field in sprite renderer with a custom shader? _Color("Tint", Vertex Color) = (1,1,1,1)
or _Color("Color", Color) = (1,1,1,1) just creates a new field instead of using the sprite renderer

[deep mason]

I have a custom shader, but it overwrites my UI like so:

  o.pos = UnityObjectToClipPos(v.vertex);
  half2 uv = MultiplyUV(UNITY_MATRIX_TEXTURE0, v.texcoord);
  o.uv = uv;
  return o;
}

im trying to make a fish-eye lense, but it returns just grey

I can't seem to find the problem, googling around this should work, suggestions?

Googling says Scene Color node is just broken / works completely differenty in every single render pipeline?

[cosmic vector]

Thank you very much 🙏

[cosmic prairie]

not broken, you need to enable it in your render pipeline settings

(for performance reasons this is turned off by default, not that it would be that expensive, just not all games need it)

it may be listed as opaque texture

[tight phoenix]

Ah that worked, thanks 👍

I got it to render now, but still working on getting to render what is directly behind it, instead of the entire screen

Thx iam tring to make it in Shader Graph in Unity but i can mix main color with second color with noise

I am working on a distortion effect.
Correct me if I am wrong but should the effect be changing as the camera moves? The distortion plane is not moving so I don't understand why it changes when the camera moves

entire graph currently

I -think- I want the effect to not change as the camera moves, only as the distortion object itself moves, but I might be mistaken in how this all works

A second problem im having is on top of changing as the camera moves, the distortion also gets more/less pronounced the closer/further the camera is to the distortion plane

The expected behaviour I would expect is that the distortion amount and position is completely unrelated to any of the camera variables

How can I achieve this?

Ah, I solved it, it was because I was adding the screen position multiple times

working grapgh for anyone struggling with a distortion effect like I was

hmm the effect does get more intense the further away from it you are still, but maybe that cant be fixed?

is there a way to correct this so it doesnt get more/less intense based on distance from the effect?

Does anyone here know how to do shaders and would be willing to help me with something?

im trying to find a doom crucible shader, I would be willing to pay someone to make one

[little widget]

I have asked this over in Amplify shader and didnt get an answer. Since many have both ASE and ShaderGraph how does one go about selecting the correct shader tool when trying to edit a shader?
What is everybody doing?

[deep mason]

I have a custom shader, but it overwrites my UI like so:

Why could this be happening?

Hi, Any idea how can I calculate a tangent while only knowing normal on a quad sphere?

[deep mason]

For a sphere there is only a tangent plane, and it is the plane 90 deg from the normal.

[merry rose]

I know what it is, but I cannot find normal simple explanation of how to calculate it

[lean lotus]

hey is there something like the cuda activemask in HLSL?

[spring sparrow]

Anyone know if you can use the animation timeline to blend between two materials.. the system in using doesnt allow for any scripting to be used just animations

[knotty yarrow]

thats unfortunate, thanks for the info

I am looking into the SRP Batcher and changing a 'color' variable on a shader/material without generating tons of new materials

Does anyone have a link to a working example of this? MaterialPropertyBlocks in the past were able to do this in the past, but ShaderGraph/Unity seems to focus on the Batcher now
