think about, for example, the simplicity of SHADER_API_METAL

or SHADER_TARGET, or UNITY_VERSION, UNITY_UV_STARTS_AT_TOP, UNITY_CAN_COMPILE_TESSELLATION, etc.

basically any of these global defined unity keywords that give you information about (a) the current target platform that the project is being run on and (b) the current unity project

all i was looking for was if there was say, a, UNITY_POST, or something

that was defined when either (a) post processing package is imported into the project or (b) post processing scripts are enabled on the camera that is currently rendering

figuring out what post processing effects are being used and how they would work with your shaders is on you (or me), the game dev, i just wanted a simple check is all =)

[meager pelican]

Then make your own keyword using your own example.
So SPECIAL_POST_PROCESSING_ENABLED. And use a C# script to set it as a global keyword, when you turn on/off effects on your camera. Why wait for Unity Tech to do it for you?

[dull lintel]

Anyone have any idea how pixel-perfect lighting and shadows like this would work? https://twitter.com/TangerineIndie/status/1421496861790253056

Tangerine (@TangerineIndie)

Those glints tho :O Creating 3D pixel art is a heck of a lot of fun :))

Looks like they're somehow baking the fragment data to some sort of map in the pixel scale of the mesh, so that the light level of each pixel agrees somehow.

[pliant pond]

Working in environments where such freedom for scripts is not supported; ex mods for games

=)

And plus, by that logic, half of Unity's features should not exist? The goal of a lot of Unity features is to streamline development and make things as accessible as possible. Nothing wrong with asking or suggesting, no need for sarcastic replies 💜

Also, user defined global keywords are scarce on older versions and not every project can be upgraded to newer ones right away.

[tired bronze]

Kinda looks like they just made sure to have bunch of square faces at regular interval. Nothing about this seems pixel perfect. You can see some thin "pixels" at the back of the axe head.

[dull lintel]

I think that's just UV bleed. If you look at the surface below the hatchet the shadow lines up with the pixels/texels of the texture. I'm not sure it's done with pixel-sized faces since that seems quite expensive.

My guess is that they're writing shadow information to some sort of baked texture for the surface and then reconciling it at texel scale.

[tired bronze]

Lines up with flat shaded faces, yes 😛

Hmm.. I guess shadows wouldn't snap to them?

[dull lintel]

They mention using Aseprite in another tweet so these are textured, not a bunch of flat shaded squares.

And yeah even then I don't think you could get the fragments to all agree easily.

[tired bronze]

It could be textured with those squares

[dull lintel]

I think the polycount would be through the roof if every pixel in that scene was its own quad.

[tired bronze]

Hence this probably hasn't gotten further than 2 models? 😛

[dull lintel]

Also the workflow for modeling that would be super painful.

That's not their only tweet. They have other screenshots and videos.

The one I linked just shows the effect best.

[tired bronze]

Ah, yea

[dull lintel]

But yeah I'm 100% confident that they aren't doing a quad per pixel here. It's some sort of multiple-pass thing at the texel level.

Getting the fragments to agree for a particular texel on the surface.

[tired bronze]

Odds are they will confirm if you ping them

[dull lintel]

Just no idea how.

[tired bronze]

Yea looking at their other tweets it seems like they did some R&D on this, so you are probably right

[dull lintel]

Yeah it's really interesting. I've never seen this effect before. Every search I do for pixel shadows is people complaining about how their shadows aren't smooth enough. 😁

I was thinking maybe it could be done as a post process effect. Somehow get a render texture with all of the lighting information, and a render texture where every texel on the screen is a unique color, and merge them.

Ooh https://forum.unity.com/threads/the-quest-for-efficient-per-texel-lighting.529948/

[hard mortar]

hello, i wanted to make police siren with fresnel. i decided to not touch bloom and real-time lights for performance( fresnel might be heavy too idk actually 😄 ).
There are any better ways to do that effect? (mobile-friendly)

[low lichen]

Fresnel isn't really comparable to bloom in this scenario. You could put some transparent sprites on top of the lights as a fake glow. It's not inexpensive, but so long as the glow doesn't take up a lot of screen-space, it should be fine.

[charred meteor]

Hey folks, I have a question about Arrays in Shaders.

In my shader, I have an array of float4s. Everything appears to work correctly regarding setting/accessing data in the array. However, when attempting to use the frame debugger tool, the editor freezes.

I have narrowed this down to being due to my array (As this is a recent addition to my shader), and it looks like it is probably down to the size of the array. If I define it as 512 elements (And allocate 512 in code) the frame debugger does not freeze. However if I go up to 1024, it will. (Ideallly, I actually want it to be larger than 1024, potentially 2048 or above).

I have tried to look online, but I couldn't really find any information about max array sizes or similar.

Additionally, when defined/allocated a larger number (like 2048), this does not cause any (visible) issues during execution, only with the frame debugger. That said, I will likely need to use the frame debugger quite a lot in my project so I can't just ignore it, and also I don't know if the frame debugger's issue is simply indicating an underlying issue that I need to solve.

(Note: I am using the array for direct element lookup, I do not iterate over it in the shader)

If anyone could give me some advice/info on this, I'd really appreciate it

[low lichen]

This thread suggests Unity limits it to 1023
https://forum.unity.com/threads/material-setvectorarray-array-size-limit.512068/

[charred meteor]

Oooo, that could be it

So the array could be larger, but setarray won't let me pass something larger than that

I'll check with 1023 and compare to 1024

[hard mortar]

thank you @low lichen . last thing i didn't understand that what you meant at your first sentence? bloom is better than fresnel at that scenerio

[low lichen]

Fresnel and bloom are like the opposite effect. Inner glow vs outer glow.

[charred meteor]

Yea, seems to freeze up at 1024. Bit annoying, but thats probably still workable for my purposes. I'm going to look at using the buffers as that thread suggested, thank you!

[low lichen]

Buffers are nicer to use, in my opinion, but hardware support on lower end hardware isn't guaranteed.

[charred meteor]

Oh I see, how low are we talking?

Like integrated graphics?

[low lichen]

It's more about the GL API version supported by the hardware.

[hard mortar]

ah okay thank you

[low lichen]

Anywhere where compute shaders are supported, buffers are supported. But it doesn't work on WebGL and OpenGL ES 2.0

Should be this list:

DirectX 11 feature level 11+
OpenGL 4.3+
OpenGL ES 3.1
Vulkan
Metal

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

[charred meteor]

Ah I see, thank you, very much appreciated

In my case I probably don't want to use them (trying to make a game that runs on potatoes). That's OK though, I think 1023 will be workable for now.

[low lichen]

It's not unheard of to use textures like buffers. You can make a texture that's 1x2048 and sample that like an array in the shader.

[kind juniper]

Do you guys happen to know how to properly work with StructuredBuffer in URP without breaking the SRP batcher? Do I need to declare it both in properties and the cbuffer?

[charred meteor]

Thanks, I'll keep that in mind! I'm still a bit new to this, is it possible to pass that additional "array texture" to the shader in addition to the maintexture?

[low lichen]

Sure, shaders can sample multiple textures. There's a limit, but it's a lot higher than 2.

[charred meteor]

Haha, cool! Well thanks for that, very handy info to know

Oh, just whilst we're on it, how would I store data within the texture? Just as a colour (i.e 4 floats packed into the colour channel?)

[low lichen]

Yeah basically. You can choose what format the data should be stored in with the texture format. There are a few dozen formats supported by most GPUs and boil down to where you want to encode it as a float or an int, 8/16/32 bit, if it can be negative or not, and if it should be normalized between the range 0-1 or not.

[charred meteor]

Nice, thanks very much for this info

[low lichen]

StructuredBuffer is an object, like textures. And like textures, they can't be defined in the cbuffer.

So buffers break batching for the same reason textures break batching

[kind juniper]

Damn... That's a bummer... But I guess I can live with that.

[low lichen]

You could make a buffer "atlas", one big shared buffer where each material/object has their own range, which can be defined as two int properties in the cbuffer.

[kind juniper]

And then I feed it into the shader as a "global property"(or whatever you call them)?

[low lichen]

Sure, though I think if all the materials have the same buffer object assigned, the SRP Batcher should notice that and be able to batch them together, same as textures.

But I don't know that for sure

[kind juniper]

Okay. I'll try that a bit later. Let me get the structured buffer per material working first.
I keep on getting errors on shader compilation. Damn, I feel like I shot myself in the foot when I decided to switch to URP... There's barely any info at all on the internet.

[low lichen]

Is it the HLSL requirement that's causing you trouble?

[kind juniper]

That too, but also because I'm using urp lit shader template that Seems to do a lot of stuff behind the scenes.

For example now I'm trying to figure out how to pass the vertex ID to the fragment shader to sample the right texture from a texture array...

[low lichen]

Are you using this template?
https://gist.github.com/phi-lira/225cd7c5e8545be602dca4eb5ed111ba

[kind juniper]

No. The one I:m using is from some article. Let me try and find the link.

[meager pelican]

Maybe try a structured buffer or a cbuffer instead?

[kind juniper]

https://github.com/Cyanilux/URP_ShaderCodeTemplates

[low lichen]

Scroll down (or up I guess?), we discussed buffers

[charred meteor]

If I find that I need to go over 1024 Ill probably start using buffers or a texture, thanks 🙂

[low lichen]

I've never used SetConstantBuffer before. I'm curious what kinda scenario that becomes useful.

[wary horizon]

I am using MinionsArt compute grass shader, but every time i add grass or change its colour. it doesnt save. Does anyone know how to solve this?

as in... it paints the grass and colours it fine... but if i leave the scene and come back, it reverts as if i never touched it. (Yes i am saving the scene before i change scenes)

[kind juniper]

Is it a tool? Perhaps it doesn't mark the changes as dirty, so the scene doesn't know that it needs to save them.

[wary horizon]

yea, tool and shader

https://www.patreon.com/posts/54164790

its like it has episodes of not saving, it worked last night, but now it wont

[torpid sapphire]

Is editing the Universal Renderer Data Filtering Opaque Layer Mask at runtime officially supported/recommended ? I've been changing this via scripts for a while for some effects but I am having issue with a 3rd party plugin (Vuforia). I was wondering if there was some issues with doing this or if I should contact Vuforia directly, thank you 🙂

[wary horizon]

i hacked around it, i just change some attributes on the tool then save. then undo my changes and save again. Strange..

[full salmon]

I've got a shader where I'm using the alpha channel from a texture to draw another color on top of the base, as well as for controlling smoothness and metallic... ness. But I'm seeing this weird halo around it, where the metallic value doesn't seem to be right. Is this an obvious thing that I just don't know about?

With smoothness up and metallic down, it looks fine:

But as soon as I bring metallic up, the halo is there again

The same thing happens with smoothness at zero:

metallic up:

the texture is just a white on black image, 2048x2048, nothing weird at all, looks perfectly sharp

[soft fern]

do you use a height map?

[merry rose]

Any idea how to get rid of this issue?, basically when looking at the sun the material is darker, when looking in direction of the sun, the material gets lighter

E

[full salmon]

Nope

It's a very simple shader really

[soft fern]

then i dont know, sorry.

[full salmon]

thanks anyway

ok, mucking around with it, it just seems to be image resizing due to the original image just not being big enough

[full salmon]

hmm, even making the image 10x bigger didn't get rid of it, just made it more "nicely" defined.

[teal breach]

do you have auto exposure on, or HDR?

[merry rose]

No image effects, no HDR

[teal breach]

😦 I thought it might be something like simulated exposure time when looking at a bright source. Is it definitely to do with 'looking at the sun' versus 'the view direction of the camera'?

[still skiff]

Hello there! I'm rendering a mesh with transparency and the mesh itself seems to have ordering issues as if the renderer ignores the z buffer. When I look at the generated shader code there is a line ZWrite Off. Is this correct? I know separate objects need to be sorted when they are transparent, but how do I force correct ordering on one mesh?
(universal shader pipeline, alpha blend)

[merry rose]

yes, when I disable lights in editor the effects disappears, also moving dir light moves the effect. Will try with different shaders etc. The shader is standard from amplify

[meager pelican]

https://developer.nvidia.com/content/how-about-constant-buffers

See the previous article too.
I'm assuming performance gain is why Unity uses CBuffers for their instancing data too.

[low lichen]

Interesting, I always assumed you could only use one cbuffer per material. I actually have a setup exactly like the example, a structured buffer of light data. I might try changing that to a cbuffer.

Actually nevermind. Looks like I changed it into multiple array properties at some point for some reason.

half4 _LightsPos[MAX_LIGHTS];
half4 _LightsColor[MAX_LIGHTS];
half4 _LightsAttenuation[MAX_LIGHTS];
half4 _LightsSpotDirection[MAX_LIGHTS];

[unreal stream]

So I have a compute shader with two kernels and some buffers.

When I call "SetBuffer" on the shader, it wants a kernel ID.

How are the buffers associated with the kernels?

Like, both of these kernels have access to these buffers...so can I use either of them for kernel ID?

[meager pelican]

Nope. It's a 1 to 1. So you'd set the one buffer on BOTH kernel ID's.
Another way to think about it is that they don't "have access" unless you set it up for them.

This lets you define multiple buffers and multiple kernels in a shader, but only assign the ones the kernel needs to it...it's binding resources at dispatch-time. That way the GPU doesn't waste resources on what won't be used.

[inner mist]

I'm trying to add a shader to a voxel marching cubes terrain generator that only has vertex colors and no UV's, so I made a shader to read from Vertex Color and Replace Color specific colors with textures, which works pretty good, but I don't know how to combine more than one back together.

Add node makes them too bright...

And Multiply node makes them too dark.

https://i.gyazo.com/540ccc1234c93d5f41b8de95554e85b4.png

When added

https://i.gyazo.com/589c2cf5bf0704ca8fdca0e399248b05.png

When multiplied

(Also need to figure out how to do tri-planar so the textures don't stretch vertically, but one issue at a time)

Any help for how to combine texture modified vertex colors would be appreciated.

It appears that the green/brown from the unmodified portions of vertex colors is being applied too

I'm not sure how to filter out the colors from the vertex color(before/after replacing it with a texture) to allow me to combine them.

[kind juniper]

Lerp the color perhaps?

I'm kinda doing the same now but with a custom shader.

Except that I'm saving a texture indices and a blend value in a structured buffer in the marching cubes algorithm. Then I'm sampling the textures in the fragment shader and lerp between them based on the blend value.

At least that's the plan. Something's going wrong at the moment.

Either the vertex IDs are wrong, or the structured buffer is not set properly, because only the first texture is drawn regardless of the indices...

[kind juniper]

Anyone has experience with Vertex id in urp shaders? No matter what I try they seem to be 0.

[shrewd coral]

hay all. does anyone know if there's a way to make a scrolling shader on a round surface loop seamlessly? im new to shader graph so I might be missing something dumb... thanks.

[kind juniper]

I assume sampling noise with the world position should work.

Or is that a static texture?

[full salmon]

I use the Blend node a lot for this sort of thing. It has all the blending modes from Photoshop, plus the "overwrite" mode which is the equivalent of "Normal" in photoshop. That will surely get you what you want, and every mode is a really simple bit of math so there's no performance hit to worry about.

[grand jolt]

Hello guys, can you tell me how to make a terrain shader for urp with shader graph? I just want to replace the base shader to alpha clip it using a spherical mask :(

[teal breach]

this video around the 6 minute mark is useful: https://www.youtube.com/watch?v=kmPj2GmoMWo

[grand jolt]

Thanks 😊

[grand jolt]

Well holes are bugged, I need to reassign the shader on the material to not have pink holes (even just linking the texture to the base color)

[winged plover]

Does anyone know how to make a leaf shader like this?

[paper sigil]

Looks like its just made with cards with a slightly blurred transparent tex

[winged plover]

okay, do you have any tutorials on it? or how to make something like it>

[paper sigil]

https://www.youtube.com/watch?v=wPBX9kqcHzE&ab_channel=LoBeyJonGameDev

this appears to be a similar effect

you could also add world offset to the shader if you want wind and stuff.

[winged plover]

okay thanks i'll check it out

[winged plover]

ok

thanks for your help

[spring night]

How can i like scale textures

like i want this:

to become this

[inner mist]

@full salmon Overwrite only shows the latest in the chain of blends, but pinlight was close except the earlier textures get muddled to nearly nothing, any suggestions?

[hard wasp]

Does anyone where the "Edit > Rendering > Materials > Convert All Built-In Materials to URP" option went in the latest beta version? I upgraded the other day and now I can't find the option anymore.

[inner mist]

There's my version and location for it, good luck.

[hard wasp]

Yeah thats where it use to be

it's not there anymore as of the latest beta

[brittle owl]

Tiling and offset node (shader graph), feed it into the UV input of the voronoi noise and change the tiling

[grand jolt]

how do you put a material to take specific amount ... like if I had a 30130 cube, I want it like a box, like every unit repeats the material?

[spring night]

but that tiles it and doesnt stretch it

[lapis lodge]

https://www.reddit.com/r/Unity3D/comments/dgxk3w/a_simulation_of_gas_giants_rings_with_4_million/f3mn13v/
does anyone know any resources similar to this method of "drawing"

the code there is a bit rusty

[charred granite]

https://youtu.be/bgRk9IL3hlE

[brittle owl]

Oops I think then it’s just as simple as taking the uv and multiplying it by a bigger number on one axis

So maybe multiply it by a vector 2 that has 1,2

[spring night]

ok ill try that then

[full salmon]

I’d say if possible to try blending a bunch of layers in photoshop until it looks right, and then look at what you did there and replicate it in the shader.

[inner mist]

I don't have photoshop, and I tried all the blend options itself in the blend node and none of them quite came out right, Pin Light was the closest but caused previous textures to be warped slightly, amplified by each step.

[hollow talon]

I am rotating my model using RotateAboutAxis node but I get weird shadows as I rotate (object casting shadow on itself). Is it possible to fix this?

thats how I rotate it

[inner mist]

@kind juniper Lerping the color ended up being the answer. Thanks for the tip!

[brittle owl]

Yeah it just kinda happens, not really a shader thing

At least I think so maybe I’m dumb

Does it do that when you rotate the object normally?

[hollow talon]

not as much, the one on the left uses URP lit shader (rotated with transform), the other uses my shader that is rotated in vertex shader

it is also more obvious without soft shadows

[thin crater]

Hey guys is there a way to create a shader for a terrain that doesn't choose the texture to use by the height but uses an array pre-generated in a c# script?

ex. a 2d array of integers representing the ID of the textures that has to be shown in the tile of the terrain at position [x][y]

[kind juniper]

It has to do with shadow settings either in your light source or render pipeline asset.

[kind juniper]

That's what I'm trying to do. So far it seems to be impossible via the shader graph. You have to write a custom shader that takes a structured buffer and uses vertex IDs.

[runic pendant]

Need some help with some matrix algebra. I have a billboard shader that calculates the position with this math, but I also need a way to calculate the world position as well.

The world position is going to be used for UNITY_LIGHT_ATTENUATION

I currently calculate it with this but it is still incorrect...

[eager folio]

@hollow talon https://gamedevbill.com/shader-graph-normal-calculation/

[lapis lodge]

any ideas?

[kind juniper]

The asteroids seem to be just dots in space. Maybe you could draw them with a vfx graph or a shader that uses a similar technique. As for their movement and interaction, there's probably gravity simulation done with compute shader or jobs system.🤔

Oh there was code in the thread!

[lapis lodge]

well i got all the rest of movement figured out, the thing is i have no idea how to draw the points Graphics.DrawMeshInstanced has a limit of 1024, Instanced indirect is a pain to do, this solution seemed better but the code doesnt work

[kind juniper]

So he basically renders them in a compute shader

interesting

[kind juniper]

What part of it doesn't work?

[lapis lodge]

The last part mainly

Linear depth 01

Is never set

[lapis lodge]

And also uses graphics.blit

[kind juniper]

I'd assume that Linear01Depth is a custom function that he wrote..?🤔

[lapis lodge]

I assumed that also, deleting that if statement did nothing tho

[kind juniper]

Oh, apparently it's unity function

https://docs.unity3d.com/2020.1/Documentation/Manual/SL-DepthTextures.html

You need to use the UnityCG include file.

[lapis lodge]

The built in shader?

[kind juniper]

yes

#include "UnityCG.cginc"

Although, might need to specify the whole path in compute shader..?🤔

[lapis lodge]

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

[kind juniper]

Also, it's probably not gonna work with SRPs

[lapis lodge]

Well if you don’t mind asking
How did you learn shaders?

[lapis lodge]

I use the normal one

Wait

S as scripted

Or S as standard

[kind juniper]

I'm still learning them.😅 Honestly, it was an incomprehensible topic for me for a long time. Recently I've started getting more into it, but there's still a lot of stuff I don't understand completely.

[kind juniper]

Scripted

[lapis lodge]

That’s a relief

[lapis lodge]

How do you find resources or blogs of it?

[kind juniper]

Umm... Google, youtube. I know it can be hard, since with such topics you don't even know what to google sometimes, but maybe getting to understand the basics of how the shaders work first and gradually getting into deeper topics is the right way. And you can always ask here if there's something you don't understand.

[lapis lodge]

well what do you consider the basics, i used a youtube tutorial of the basics and sebastian league to understand them (dont get me wrong im very new), and most of my actual code in the shader was copied from a blog of a galaxy simulation and many changes cause incomplete

[kind juniper]

By basics I mean what vertex/fragment shaders do and how data is passed between them. Maybe try looking into some simple unlit shaders and play around with them, try including some features on your own.

[lapis lodge]

ok thanks, last question
in the reddit post he sent the positions and did the operations in update, in my current version i send them and get them because the operations are done there
is it more efficient to do them in the cpu or gpu?

[kind juniper]

You mean this?

In Update() I simulate attractors:
foreach (Attractor a1 in attractors){
foreach (Attractor a2 in attractors){
if (a1 != a2){
a2.velocity += (a1.position - a2.position).normalized * a1.mass / Mathf.Pow(Vector3.Distance(a1.position,a2.position),2)*timeStep;
}}
a1.position += a1.velocity*timeStep;
}
...and send an array with their positions and masses to compute shader every Update().

[lapis lodge]

yes, i think theres a possible optimazation in this way
the other way is having a thread for each particle

[kind juniper]

This is not the particles, but the attractors( the moons that he adds in his video).

[lapis lodge]

oh well, the concept is still there

[kind juniper]

And yeah, I think you could do that with jobs or a compute shader too, but if the count is low enough, the overhead might be more than the processing speed.

So, you just gotta play around and see what's faster with your numbers.

[lapis lodge]

so
is nested loop
and thread for each particle

which is better at larger scales

?

for
for

or

thread
for

[kind juniper]

thread for each particle. That's what GPUs excel at. Because they have thousands(I think) of small processors in them, each processing some small piece of code quickly.

[lapis lodge]

it is said doing set and then get repeatedly kills performance

[kind juniper]

Jobs would work too, but for something like this a compute buffer would be way faster imho

[lapis lodge]

we already tried DOTS the limit is 10k, shaders is x10

[kind juniper]

Again, you'll have to test, because it depends on the number of things that you want to process.

[kind juniper]

What limit?

[lapis lodge]

limit as the maximum that it is good

because the operation is O^2

[kind juniper]

amount of threads?

[lapis lodge]

for each particle theres a for loop of the particles

so having 100
made 10,000
calculations

thats a way to put it

[kind juniper]

I still don't understand what you meant by a limit of 10k? Is it the amount of particles that you send to be processed in jobs?

[lapis lodge]

yes

[kind juniper]

I see. Well, I wouldn't rely on any hard numbers like this, because it will vary vastly based on the hardware and the current state of the system. But yeah, compute shaders are definitely faster than cpu threads for such tasks.

[lapis lodge]

massive thanks, i will now go to do homework

but a last question

final

do shaders simulate light, the same way you can use emmisive materials?

or can use emmisive materials? or i would have to do more coding for that?

[kind juniper]

You mean compute shader?

[lapis lodge]

any shader that can be used to draw meshes/points in screen

[kind juniper]

I mean, shaders are what renders everything, the materials are just blocks of properties that are passed into the shader. So, the answer is: your shader renders things the way you tell it to render things, whether it's lighting or emission.

In case of the guy from reddit, he was using a compute shader, which is not exactly a regular shader(not used for rendering usually). He was basically creating a texture the same way that you could do on a CPU with texture.SetPixel/s.

So, no, if you follow his example, you won't have emission or any kind of lighting.

You could add another layer on top with image effects/ post processing to achieve a glow, but that's a different story.

[lapis lodge]

thanks you been very helpfull

[round nova]

how do i adjust the blending and color mode so that my sprites stop becoming this ghostly white. I tried some combinations but with weird results

[kind juniper]

Try setting the surface type to opaque🤔

[round nova]

okay

setting it to opaque turns it fully untransparent

i guess i just want the background to be transparent. but keep the sprite at full color

[dawn ginkgo]

help, why is my normal map really pixelated?

i used the grid subshader and fed it into normal from height

[kind juniper]

Use alpha clipping and set your texture to use alpha. Assuming your textures background is really transparent.

[round nova]

yay checking alpha clipping worked, thanks

[worn furnace]

Woo! Made a stochastic blender in shader graph

[kind juniper]

When I call material.SetBuffer(buffer) and then call buffer.Release(), does it actually mean that the buffer is not passed into the shader when it renders?

[low lichen]

The buffer values aren't copied if that's what you mean. What should happen is the buffer is destroyed so there's no data to access, but maybe that doesn't happen immediately.

[kind juniper]

So if I release the buffer immediately, the structured buffer in the shader remains empty? At what point in the rendering pipeline, does unity upload the buffer to the shader? When it renders that material?

[low lichen]

The data is never "uploaded" to the shader. The shader has a reference to the buffer, like textures. If you destroy the object, the reference isn't valid anymore.

[kind juniper]

Ah I see. Thanks for the clarification. I can't seem to get it working... Either the buffer is empty, or the indices are completely off...😫

[static cipher]

Hello, I'm working on a vegetation system that works by generating a bunch of positions in a compute shader, culling them in another compute shader, and doing a DrawMeshInstancedIndirect to render them all.
has anyone encountered problems with specific graphics cards? A few users have reported that on some APUs the plants do not render.
I'm a bit lost on how to debug this since its a compute shader error only on some graphics cards.
I suspect it might be something with the instruction set (maybe) but I really don't know how to debug this kind of things 😭 😭 😭

https://sites.google.com/view/arnauaguilar/projects/vegetation-engine?authuser=0
Here is a bit more info on the vegetation system, but only the "Hidden areas" or plants work this way

[polar granite]

Guys, I'm gonna be honest here. I'm trying to make cum for my hentai game, but I can't find any good documentation.. I found this tutorial for blood and changed it white, but it looks awful. lol

Someone here that could lead me into the right direction?

It has to be sticky and have some basic physics

[teal maple]

Has anyone ever seen this issue when building out to Windows?

[humble walrus]

Hi. I'm new in Unity. I have question about blending two textures in two differen uv sets

how to achive in Unity something like this:

[mental bone]

You have a uv node in shadergraph that you can select the uv channel, you have a sample texture node and a multiply node as well. So prety much the same thing @humble walrus

[humble walrus]

Ok thanks :)

[dull lintel]

Not sure how to phrase this question right, but is there any way to add a step after the regular PBR inputs of a URP Shader Graph surface shader? Like if I want it to set the colors of a fragment according to the albedo/normal/metallic/smoothness etc. but then override it at the very end sometimes with a plain unlit color?

Use case: I'm trying to get some areas on an otherwise PBR model to just be flat black with no light response whatsoever, but can't seem to do that with a regular lit URP shader (no matter the setting they still pick up or reflect light at least a little bit).

[meager pelican]

You can add a per-pixel map for metallic and smoothness, for example. Just like a texture, only it's a metallic map....
and the texture map could hold your "plain unlit color" more or less. You'll still get hit by shadows though. And lighting will impact things.

The only other thing I can think of is to mess with emission for your base color. But whatever you're doing I try to do it to the pixel ONCE, not in a separate pass if I could at all avoid it.

Or stuff some values in some "override" texture that you invent. And just substitute that.

[dull lintel]

Yeah, I've tried those things unfortunately. Emission only works for light colors, not dark. And even if I do like, full metallic, full roughness, or zero metallic etc. you still see some light reflections for point lights and the like on the surface. It's very dark, but not unlit total black dark, which is what I'm trying to achieve. And yeah, doing it all in one pass is the goal. I've done it in a hacky way by using an alpha cutout and having the object rendered twice -- total black and then again with everything that isn't cut out, but that's pretty wasteful.

[wanton stone]

Is object space in shaders synonymous with local space for transforms? Or is it normalized?

[strong hedge]

i have a huge computebuffer with voxels but its mostly empty space and i need a way to render them anyone got any idea?

[meager pelican]

What about the "override" texture?
Is this static, or dynamic coloring?
IDK your use case. I mean, if you can "just" update a texture on the object according to its UV coordinates....
IDK if I'm making sense.
Some sort of static-color-splat. Like a decal.
Should be able to work that out in one pass.

But if you have to compute it dynamically, that's a tad harder...

And don't forget about stencils too, depending on your needs.

[dull lintel]

The override texture would just be flat black. Think of like, an object with a vent on it -- I want the negative space in the vent to just be unlit black rather than having to model an actual gap. Thinking of it as a decal could work but I'm not sure how to achieve that in a single pass URP PBR shader.

There's no combination of roughness/metallic that makes the given pixel completely unlit, and black won't work for emissive.

[meager pelican]

Well it depends on if you mean a Shader Graph shader, or hand-edited one. 😉

But the other thing is lighting. Lighting is a large array of topics...but there's self lighting and then there's additional lighting passes.

Maybe, if you ONLY WANT FLAT-PURE-BLACK you could flag pixels on the screen as needing such, and then later in a post processing pass AFTER lighting, turn them black.

How to go about that gets complicated if it varies pixel by pixel.

Sounds like you want to avoid all lighting...any hint of it.
I'm surprised that pure-black cannot have roughness/metallic that results in pure-black results, but I admit I haven't tried it in recent memory.

Do your game requirements (target platforms) all support multiple render targets?

The other way is multi-pass, maybe a render feature or something.
Then you could use a stencil, and clip any pixels that won't be pure-black. So the stencil is just the pure-black pixels.

Now you're up to 3 passes.
The original draw all colors pass.
The stencil pass that just draws the black pixels, all others clipped.
<lighting happens>
a post processing pass that blacks out stenciled pixels.

This all seems like an "ouch".

[dull lintel]

Probably what I'm going to have to do is just take the source for the URP PBR shader and make my own edited version of it that lets me bypass certain pixels to unlit based on a map texture.

Was hoping to avoid that though.

Especially since that shader is quite complicated and changes a lot version to version.

[mystic dagger]

I have an array of Color32s that I want to sample in a compute shader

do I need to convert it to a texture2d?

[meager pelican]

You can pass arrays directly. Note that shaders like floats.
There's size limitations, IDK off hand how large but several K I think.

[mystic dagger]

color32s aren't floats i thought?

[meager pelican]

Or use a structured buffer.

[arctic sierra]

what's the syntax for initializing a struct in a compute shader?

i've tried a lot of ways and nothing seems to make the compiler happy

[meager pelican]

https://docs.unity3d.com/ScriptReference/Color32.html

[mystic dagger]

right

[meager pelican]

They're bytes...8 bits each x 4 = 32 bit color value.
If you want 4 floats, use Color not Color32

[mystic dagger]

I need 4 floats eventually

[meager pelican]

I'd just use normal colors if that's the case. Sometimes color32 is faster and it's always more compact, but there's trade offs.
My 2 cents.

[mystic dagger]

this is how i'm doing it right now:

#pragma kernel Write

RWTexture2D<float4> PositionMap;
//RWTexture2D<float4> _NormalRT;
RWTexture2D<float4> ColorMap;

StructuredBuffer<float3> _PositionCBuffer;
//StructuredBuffer<float3> _NormalCBuffer;
StructuredBuffer<float3> _ColorCBuffer;

int _TextureSize;

int GetI(uint3 id)
{
    return id.y * _TextureSize + id.x;
}

[numthreads(8,8,1)]
void Write (uint3 id : SV_DispatchThreadID)
{
    int i = GetI(id);

    float3 pos = _PositionCBuffer[i];
    //float3 nor = _NormalCBuffer[i];
    float3 col = _ColorCBuffer[i];

    PositionMap[id.xy] = float4(pos.x, pos.y, pos.z, 0);
    //_NormalRT[id.xy]   = float4(nor.x, nor.y, nor.z, 0);
    ColorMap[id.xy]    = float4(col.x, col.y, col.z, 0);
}```

[meager pelican]

You have them as floats in your buffer. You might be getting an auto-conversion from Color32 to color when you assign stuff in C# anyway.

In a shader, a color32 would be an INT (32 bit int). You'd mask off the appropriate 8 bits or something (I think).

So you're already using floats.

[mystic dagger]

I suppose ColorMap could be integers 0-255 and I could just divide in VFX graph

[meager pelican]

But there's nothing wrong with using a structuredBuffer of float3, really. GPU's like things float4 aligned though, if you can afford the space.

Also, CBuffers can be slightly faster (like 10% or so). But meh right now.

Or use an array.
But if you want it Writeable, stick with the StructuredBuffer, IMO.

[meager pelican]

But why?

You'd end up masking and bit shifting.

It's nice if you have very large arrays of colors, since color32 is 4x more compact.

So it all depends...

[mystic dagger]

because my data has changed and it's coming in as color32[] now

sticking with structuredbuffer like you say

I need to either convert from color32[] to color[] in C# (this has to be fast) or in the shader i guess?

#pragma kernel Write

RWTexture2D<float4> PositionMap;
RWTexture2D<float4> ColorMap;

StructuredBuffer<float3> _PositionCBuffer;
StructuredBuffer<uint> _ColorCBuffer;

int _TextureSize;

int GetI(uint3 id)
{
    return id.y * _TextureSize + id.x;
}

[numthreads(8,8,1)]
void Write (uint3 id : SV_DispatchThreadID)
{
    int i = GetI(id);
    float3 pos = _PositionCBuffer[i];
    float3 col = _ColorCBuffer[i];
    PositionMap[id.xy] = float4(pos.x, pos.y, pos.z, 0);
    ColorMap[id.xy]    = float4(col.x, col.y, col.z, 0);
}```

(should have been using int4 but this also did not work)

this didn't throw any errors but it's all white

so I assume this is wrong

[kind juniper]

@mystic dagger how are you retreiving data and checking it?

[mystic dagger]

it's coming in as col32[]

[kind juniper]

Share the c# code

[mystic dagger]

one sec will give more detail

will pick out the relevant parts

    private static readonly int _TextureSizeID = Shader.PropertyToID("_TextureSize");
    private static readonly int _PositionRTID = Shader.PropertyToID("PositionMap");
    private static readonly int _PositionCBufferID = Shader.PropertyToID("_PositionCBuffer");
    private static readonly int _ColorRTID = Shader.PropertyToID("ColorMap");
    private static readonly int _ColorCBufferID = Shader.PropertyToID("_ColorCBuffer");
    private ComputeBuffer positionCBuffer = null;
    private ComputeBuffer colorCBuffer = null;
    const int length = 1280 * 600;
    private readonly float TextureSize = Mathf.Sqrt(length);
    NativeArray<float3> positions;

    RenderTexture CreateRT(int texSize)
    {
        return new RenderTexture(texSize, texSize, 0, RenderTextureFormat.ARGBHalf)
        {
            enableRandomWrite = true,
            filterMode = FilterMode.Point
        };
    }

…

    public void Start()
    {
        int size = Mathf.CeilToInt(Mathf.Sqrt(length));  
        positionRT = CreateRT(size);
        positionRT.Create();
        colorRT = CreateRT(size);
        colorRT.Create();
        computeShader.SetInt(_TextureSizeID, size);
        computeShader.SetTexture(0, _PositionRTID, positionRT);
        computeShader.SetTexture(0, _ColorRTID, colorRT);
        vfx.SetTexture(_PositionRTID, positionRT);
        vfx.SetTexture(_ColorRTID, colorRT);
        positions = new NativeArray<float3>(length, Allocator.Persistent);
}```

Then later

        Color32[] colors = GetColorArrayFromExternalSource();
        
        positionCBuffer?.Release();
        positionCBuffer = new ComputeBuffer(length, sizeof(float) * 3);
        positionCBuffer.SetData(m_meshModificationJob.positions);
        computeShader.SetBuffer(kernelHandle, _PositionCBufferID, positionCBuffer);
        colorCBuffer?.Release();
        colorCBuffer = new ComputeBuffer(length, sizeof(float) * 3);
        colorCBuffer.SetData(colors); //!
        computeShader.SetBuffer(kernelHandle, _ColorCBufferID, colorCBuffer);
        computeShader.Dispatch(kernelHandle, Mathf.CeilToInt(TextureSize / 8.0f), Mathf.CeilToInt(TextureSize / 8.0f), 1);

[kind juniper]

Yeah, I think you need to convert Color32 to Color before passing it in. Is there any reason it's Color32 originally?@mystic dagger

Also, in your computer shader you assign just one uint value to a float3, so I'm not sure how that is converted.

[mystic dagger]

Yeah that was a mistake. I tried uint4 to uint4 as well which gave me blackness

[mystic dagger]

Is there a fast way to do this?

[kind juniper]

Loop the array/list and cast to Color

[mystic dagger]

That sounds expensive

[kind juniper]

But why is it Color32? Maybe change the way you create the array?

[kind juniper]

Shouldn't be too expensive.🤔

[mystic dagger]

I'll see if I can change it when its created

[kind juniper]

Could also run another compute shader that will convert it to regular color.

[kind juniper]

How are you creating it?

[vocal narwhal]

Is there really a need to do this?

Use StructuredBuffer<uint> in your shader and that should accept a whole color32 just fine (uint is the size of 4 bytes or 32 bits)

[kind juniper]

Then it's just a problem with how he assigns it to float4?

[vocal narwhal]

uint colorIn = ...;
half4 color = half4(colorIn & 255, (colorIn >> 8) & 255, (colorIn >> 16) & 255, (colorIn  >> 24) & 255) / 255.0;```

[kind juniper]

Ah

[vocal narwhal]

They just randomly use = across two incompatible types

[kind juniper]

So 1 uint holds the whole color32 data?

[vocal narwhal]

Yes

[mystic dagger]

There are 3 color channels though

[vocal narwhal]

Four, one alpha

[mystic dagger]

So should it beuint3

Right I just pack a 0 at the end

[vocal narwhal]

No

uint is the size of 4 bytes or 32 bits

Color32 is 32 bits long, each channel is 1 byte

[mystic dagger]

Got it

[vocal narwhal]

The compute buffer should be new ComputeBuffer(colors.Length, sizeof(uint));

[mystic dagger]

I'm walking back home will try in a few minutes

[mystic dagger]

this part is giving me an error relating to threading :/

[vocal narwhal]

threading?

[mystic dagger]

oh wait no I had a typo

yep. I have some multithreaded stuff in here. Long story

eventually it will be on the shader

the colors are not mapped correctly

#pragma kernel Write

RWTexture2D<float4> PositionMap;
//RWTexture2D<float4> _NormalRT;
RWTexture2D<half4> ColorMap;

StructuredBuffer<float3> _PositionCBuffer;
//StructuredBuffer<float3> _NormalCBuffer;
StructuredBuffer<uint> _ColorCBuffer;

int _TextureSize;

int GetI(uint3 id)
{
    return id.y * _TextureSize + id.x;
}

[numthreads(8,8,1)]
void Write (uint3 id : SV_DispatchThreadID)
{
    int i = GetI(id);

    float3 pos = _PositionCBuffer[i];
    //float3 nor = _NormalCBuffer[i];
    uint col = _ColorCBuffer[i];

    half4 color = half4(col & 255, (col >> 8) & 255, (col >> 16) & 255, (col >> 24) & 255) / 255.0;
    PositionMap[id.xy] = float4(pos.x, pos.y, pos.z, 0);
    //_NormalRT[id.xy]   = float4(nor.x, nor.y, nor.z, 0);
    ColorMap[id.xy]    = half4(color.x, color.y, color.z, 0);
}```
did i miss something?

[vocal narwhal]

looks correct as far as I can see

[paper sigil]

Hey, I want to make a sort of "Shader interactor" for my water shader. Ideally, id like artists to be able to add areas of froth/rapids to this river.

I though about getting an intersection between a mesh and the river, but the river doesn't write to the depth buffer.

[vocal narwhal]

If you just want to add depth-based foam around rocks and the rivers edge you do not need the river to write to depth. You have the depth of the surface behind it, and you have the position of the current fragment, you can use that distance. There's an implementation for depth-based fog like that in shadergraph pinned to this channel

[paper sigil]

Sure, and i'm already adding foam to the intersection between the river and ground, but id like to have an intersection between the river and an invisible mesh, used to paint in foam wherever i want.

[vocal narwhal]

You'd usually paint vertex colours onto the mesh to do that sort of thing

[paper sigil]

Maybe im just trying to be overly clever here, but id like something that i can also update a runtime too. Say if a boat is moving down the river it would have a froth trail behind it. The plane is super low poly also.

[vocal narwhal]

I'd make the boat's trail be entirely separate from whatever is authored onto the river

[paper sigil]

Got it working. Basically i have a camera setup with a render texture only rendering a certain layer, and i blur that, then sample it for the foam

[runic pendant]

I sort of asked this question before but it got swallowed up by other comments: How do I calculate the world position of verticies so that it reflects the billboarded verticies of positions?

[grand jolt]

Expected outcome,

Result

The actual texture is square, but it seems unity doesn't run my shader for completely transparent pixels

Any way to fix this?

[digital gust]

Can you show your scene view of this object?

[vestal hearth]

hey, isn't URP particle shader supposed to be available? not visible for me on unity 2021.1.17

[digital gust]

2012.2.0b12 here: @vestal hearth

[vestal hearth]

strange.. could it be a setting that have turned it off somehow?

[digital gust]

URP version outdated?

Dunno if there is a change within my beta

URP 12 on my side

[vestal hearth]

11 here

also got VFX plugin, dunno if theres a conflict with it

[digital gust]

Well it could be URL 11-12 difference, using VFX too

[vestal hearth]

maybe not.. i did find a PFX asset in my project that contain URP particle shader. but even here, its not displaying in the menu

[digital gust]

Erm you rdropdown is saying URP/Particles/Lit, so where is that coming from? @vestal hearth

[civic fern]

sorry to interrupt but i have a question - im using a material on a canvas image renderer, and i figured that the "source image" of that component was nullified by the main text on the material i used, so i was like "whatever ill just manually make a greyscale material" but then i realised sprites-default does it just fine

so how do i make a material take the source image from its image component as its maintex?

[digital gust]

As you say, as soon as the material has a texture, it will overwrite it, so you might have to use either a script or just set the right image in your material. Did you try to not set the _MainTex in your material and see if it might work?

[civic fern]

interesing no i didnt actually

just setss it to a white square

what if i dont have a main tex at all? what happens?

nvm it works

lol

[digital gust]

😄

[civic fern]

i mistyped it to _MainText

and nobody batted an eye

[digital gust]

oh, well 😄

congrats I guess, or congText 😉

[civic fern]

no it doesnt actually it just makes it not work at all :0

actually maybe not?

idek

gimme a sec

it works fine i claled the shot too quickly

[wispy stump]

if i had a built in pipeline shader how would i convert it to a HDRP shader?

[kind juniper]

Depends on the shader, but if you want it to use all the benefits of HDRP, you'll probably have to rewrite it from 0

[wispy stump]

uhhh how would someone even go about doing that?

[kind juniper]

Research the difference between built-in and hdrp and rewrite it. What is your shader based off? Is it a lot shader? Surface shader?

[wispy stump]

i dont know tbh

[kind juniper]

I've upgraded(kinda rewrote) a built-in shader to urp. It was very close to a regular shader, so I just used a urp lit shader template and it was a bit complicated. HDRP is probably several times more complicated.

[kind juniper]

What does it do?

What do you use it for?

[wispy stump]

its a character shader it gives them an anime style look

[kind juniper]

Ooh. Well, you'll need to research how it works and determine what and how needs to be converted for it to work on hdrp.

Atlre you sure you need hdrp for anime style though?

[kind juniper]

Probably easier to look up a tutorial for a similar shader done with shader graph. There are plenty of those.

[wispy stump]

we're trying to prepe for the depreciation of the built in render pipeline

this shader is a bit specific. lol

[kind juniper]

Probably not gonna happen in the few coming lts's

[wispy stump]

i could send it to you via dm

it'll also allow more interesting things environement wise

[kind juniper]

Are you planning to use a version where built-in is deprecated? Could be a few years untill it's even in beta.

[wispy stump]

if we were usign hdrp

[kind juniper]

Nah. I'm going to sleep soon anyway. If you share it here, me or someone else might have a look when we have time.

[kind juniper]

Hdrp is mostly for ultra realistic graphics. I'm not sure you need something like that with anime style looks..?🤔

[wispy stump]

dont want to publicly post it tbh, oh well

[kind juniper]

And many similar things can be implemented in built-in pipeline with a bit of effort.

[pseudo narwhal]

if you are concerned about pipeline obsolesence you could look at https://assetstore.unity.com/packages/tools/visual-scripting/better-shaders-standard-urp-hdrp-187838 and/or https://assetstore.unity.com/packages/tools/visual-scripting/amplify-shader-editor-68570 both have been use for production ready, performant shaders in all pipelines. Both kinda abstract the pipeline away.

[gleaming notch]

If I create a 2d shader, and my sprite has a normal map assigned in secondary textures, so I need to do anything in the shader to have the material use the normal map? Do I just drop in _NormalMap as a property and plug it in to the normal in the sprite lit master node?

Or does it do that automatically?

[ocean wharf]

hi, im very new to writing shaders. I'm trying to add emission into the default standard surface shader but I cant seem to make it use the dedicated emission map over the diffuse

ill throw the code into a hastebin and post a picture of whats happening

https://hastebin.com/odolukaral.properties

[opaque sorrel]

Ayo, so I was looking around for how to do this effect to sprites, I found an asset on the assetstore, but I was wondering if there's a method to do it more close to my example

https://youtu.be/3gOEBgMkMR0?t=343

Watching the video, it basically seems like there's some circle object below the sprite that moves upward and deteriorates the sprite as it passes over it. I was to do this, but like from top down (something akin to Undertale). I just don't even know where to start on this tho or resources.

Like how would I chew away from a sprite at the top (especially if it's, let's say, animated) and deteriorate it and make pieces from it fly off and disappear like that?

[carmine ivy]

Can I use shader buffers on a WebGL build? if not are there any other ways to send an array with vectors to a shader?

[twin totem]

Soo umh i need some help.
Im trying to blend between two skyboxes that are made of panoramic pictures and I haven't found any posts about blending between two skyboxes.
Does anyone have a solution to this?

[meager pelican]

Well, if I were to try that, I'd

1. not confuse the sprite and the flying stuff...two different things (probably).
2. mask off the sprite over time (pass in time intervals or something) modulating the edge with noise. And I'd overlay, by whatever means, some animated flying stuffs, possibly distorted by noise and some random offsets to make it appear unique.

[meager pelican]

Define "blend". What do you want to do? There's many ways to "blend".

But I'd get a basic skybox shader working first. Once that is done, I'd add the 2nd with a switch to make sure you can swap between them and they look good.
THEN, I'd blend the two, instead of switching between them.

As to blend, if you want to fade one to the other, use a Lerp() function and pass in the blend amount. That's one way.

[opaque sorrel]

hmm. I just wish there was a way for one mask to reinterpret and like reflect onto the other mask the color being tossed up. but yeah, it's definitely two different like mask

[twin totem]

I want to fade them. But i will have to look some tutorials up because im really new to shader writing.

sry for the late reply i was busy

[dusk tapir]

Im trying to pass through an array of Vector2's to my shader, and i noticed the only vector arrays there are functions to pass, is Vec4s(and Colors), more specifically i need float2's

should i just pass through the Vec4's? and if the variable it is sending to is a float2, will it delete the excess data, or overflow it to be the next element

[hollow dagger]

Does anybody know why my shader is doing this?

[vocal narwhal]

Because you are not using the alpha

[hollow dagger]

Knew it had something to do with that, thank you

[dusk tapir]

should i ask questions about HLSL and scripted shaders here, or in #archived-code-advanced ?

[vocal narwhal]

Here

[dusk tapir]

ok, what is the best way to pass through an array of Vector2s/ float2s from script to shader

i have to pass through an array of Vec2s, and a corresponding array of the same size of Vec3s

when i was making a compute shader i remember that structured buffers would have data carry over (if i passed a vec4 to a float2, each vec would be 2 entries), but idk if that will happen with .SetVectorArray

[spring river]

I'm in the early planning stages of a new game and I'm wondering if anyone has any ideas on a 3D to 2D 'pixel' look. This is different than the mainstream render texture method - I don't want the game itself to be low resolution - I want the render of the world to look low resolution. It's hard to explain, but older style games like Roller Coaster Tycoon are exactly what I mean.

This factorio trailer is a good example: https://www.youtube.com/watch?v=DR01YdFtWFI You can zoom in and see the sprite sheets pixels; however the actual runtime resolution is higher. This is something that can't be achieved with the render texture method. Instead of rendering sprite sheets, I'd like to render the game down at runtime to achieve the same look.

If anyone has any ideas, I'd love to hear them. This will inform if the game is made using a 3D or 2D pipeline, so I'm trying to get as much info on it as possible.

[cinder chasm]

Hey y'all, anyone having issues with editing subgraphs in the SRP shader editor?

I'm getting exceptions which are breaking the UI any time I edit one

[worn furnace]

I need help understanding a math concept for the shader I'm writing.
Normally, when I blend two textures together I square them, add them, then square root them (Pythagoras) because that gives me a smooth constant intensity blend between them. A big reason that this works is that colors can only range from (0,1) so you don't lose any information.

However, the problem I'm running into is when I blend the normal maps. I think the issue I'm having is that because the normal vectors can have negative components, when I square, add, square root, I'm basically taking the absolute value of the vector, so anything that was negative has lost that information. And my normals are looking super weird.

Is there a math way to smoothly blend normals together without accidentally getting the absolute value of them?

[cinder chasm]

Do you want the result of blending -0.2, 0.4 to be 0.1 or 0.3

If I'm understanding correctly, 0.1?

Or uh actually, you don't want an average do you

Is your mathematical operation based on any real principle, or is it just something that worked for you via fiddling? Because I don't think pythagoras has anything to do with smoothing values

[cinder chasm]

My personal suggestion would be to use the average of the two vectors and then normalise it, since this will give you the direction between the two, which is what I'd expect out of smoothing directions

[worn furnace]

so just do normalize((a+b)/2)?

[cinder chasm]

Yes, that's how you get the average direction of two vectors. It's what I'd do if someone asked me to smooth normals

[mental bone]

normalize(float3(A.rg + B.rg, A.b * B.b)); this is from the normal blend node in shadergraph

[worn furnace]

Thanks all for the help. What I ended up doing actually was removing the Z component, blending the X components, blending the Y components, then using the reconstructZ function to generate a valid Z from the X&Y

and it looks gorgeous 😄

[thin crater]

Hello! I've spent days trying to find a solution to do a custom terrain texture in a mesh (that's also my terrain). After a lot of time I managed to get that with a shader graph: I set one texture to the shader via c# that represent the mask, and has only two colors (e.g. green and red), and every chunk has a different mask, and the real biome texture is set in the shader settings, on the material. However this process takes literally ages to do, and I have to add 2 textures and one variable for each biome that I want to add, every time. Is there a way to create a "layer system" like with the normal terrain, where I can add an "array" of texture pairs/other variables relative to one biome?

[worn furnace]

Here's a strong sun angle shot showing off the working normals:

[thin crater]

My solution is similar to this (https://www.youtube.com/watch?v=bA9BXvYfaB0), except that I have various chunks and I set the uv map relative to the mesh position, to do the flawless continuous effect on the mesh

[meager pelican]

Lerp.
It's a range from 100% of one and 0% of the other to the other way around. Using "t" value of 0 to 1.0.

[meager pelican]

What is the size of the arrays?
If not too-huge, use vector4s for everything. Why? Because GPU's like things aligned on vector4 sized byte boundaries for speed of memory access. 😄
So if you can afford to burn the memory, burn it up.

That said, just my 2cents. I mean, you can pack 2 vector2's into 1 vector4 (they're called float2 and float4 in shaders, but meh). You'd compute the index and access either the xy or the zw depending on odd or even index.

For the float3, I'd use float4's. Again, my 2cents.

[twin totem]

Ok thx. But i still have to learn shader basics ( probably shader graph because im too dumb for the text thing ) and i already have seen the lerp block.
So do you know, how i can import in shader graph 2 Skybox textures ( the lerp part seems easy, just connecting them and feeding in a float value ) and output them as a new one?

I cant find the PBR Master block that everyone talks about in tutorials

[meager pelican]

Skybox shaders are "special" so IDK off the top of my head.
But google it. This is just the first ref I found, so YMMV.
https://medium.com/@jannik_boysen/procedural-skybox-shader-137f6b0cb77c

In your case, you'd pass in a "t" value to the shader as a uniform, that indicates how far along the blend between the two is for each frame.

Then you'd blend the two textures with a lerp node.
So you'd have TWO textures defined as input into SG, a t value, and a lerp for the result. Whatever you do from there...is you programming.

The "PBR master block" has been replaced with TWO parts...one vector part and one fragment part. Just pretend the two of them are the one big "master block".

Use a lit shader if you want PBR, but IDK why you want that for a skybox. I'd assume they'd use unlit for that.

[twin totem]

Thx im gonna try it out

[vestal hearth]

im not sure, i think i previously had URP particles available, but at some point it disappeared from the shader list

[dusk tapir]

Alrighty, ill give it a go, the max size should be around 50, so, memory isnt an issue

[orchid zephyr]

Hi I am having a problem that I have no idea how to solve. I have these two planes with a shader material on them. However, this makes them treated as two seperate planes with materials, but what I want is to have them treated as one large plane. So instead of it being 2 planes with the 10x10 grid on it, I wante each to have a 10x5 grid on it making the grid as a whole 10x10

[mighty fox]

For what purposes i can use signed distance field in 2d?

[low lichen]

It's often used for sharp font rendering with low resolution SDF textures, but of course can be used to draw any shape/symbol. You can get vector like quality and sharpness from like a 64x64 SDF texture.

[lucid current]

is it possible to apply fresnel effect on a square sprite?

[meager pelican]

Cut the x (or y) direction of the UV's in half, and add a 50% offset for the 2nd one.

Tiling and offset.

[hollow dagger]

I am having an issue. I am using a custom lit shader for my trees, and my tree color is extremely dark. How do I get this tree color to look like this?

Here is what it looks like right now

The only difference between the two is one uses a sprite lit shader, and the other uses a regular lit

[meager pelican]

One way is to scale the colors up. So add a slider from 1.0 to 2.0 and multiply the color by that.
But black will still be black, because 0 multiplied by anything is still 0. Some of those colors are quite dark....

Or check your lighting to figure out why it is so dark. Maybe add ambient light.
Is the texture that dark?

Or post the shader.....see where you could add an ambient value.

[twin totem]

Hey. Thank u really much, the webside helped me a lot and i now have a basic understanding of shader graph. It also look really pretty :D

[orchid zephyr]

is there anyway to stop wrapping on a shader

[hollow dagger]

The color is actually set to white here. Let me post the shader

[meager pelican]

But it came out dark. So you must be setting the texture property on the material, even if you're multiplying it by 1 (1,1,1 is white as I'm sure you know).

So my questions remain.

What does the texture look like?
Are you using a lit shader?

You could also try messing with smoothness and metallic values.

[hollow dagger]

The texture looks exactly like how it looks in this image here:

And i'm using a lit shader

[meager pelican]

OK, well I don't see the green moss on the tree in your problem-image. And the problem-image looks to be a close-up of that ?center tree? or is it the one on the left?

Anyway, check lighting settings first. Since ambient light, shadows, light intensities and such will change the results.

And the other thing I mentioned before is that you can lighten it up by multiplying with values GREATER than 1.0.

And try checking the metallic and smoothness values.

[meager pelican]

Sure. If "in the shader", clamp the UV values to between 0.0 and 1.0. Also check texture settings in the inspector for other options if you want to do it with a sampler state.

Or if using SG, set the sampler state using a sampler state node.

I'm 99% sure you can do that state setting in code in non-SG too in the shader.

[orchid zephyr]

ty. I ended up going in another direction, but I am sure this information will be useful anyways

[gleaming notch]

Hey guys, I'm having an issue in that sprite masks do not mask the normal map texture. The only thing I can think of is to write a new shader that takes the mask sprite renderer as an input and only displays normal maps where the sprite overlaps with it. Does anyone know how I can accomplish this? I am very new to shaders.

Here is the issue displayed

As you can see the feet are available outside the mask space

I basically want to check if the mask texture exists at a location, and if not, multiply the rgba value of the normal map by 0

Can anyone tell me what the equivalent of dFdx and dFdy using GLSL ES 2.0? (partial derivative)

Specifically, I want to use fwidth, but it doesn't exist in version 2.0.

abs(dFdx(uv)) + abs(dFdy(uv))

I can use glsl #extension GL_OES_standard_derivatives : require

[brittle berry]

Hey all, I want to use some Vector4 UV channels in my shaders. Are there file formats that support 4-challen UVs? FBX import/export in Unity seems to only support 2-component vectors.

[west eagle]

@brittle berry why vector4 uv? if you wanna input extra data into vertices there is plenty other ways.

[brittle berry]

Mostly because I want to store it as a 3D file

In-memory only, I have no preference. But for saving baked data, UV seems to be the easiest placeholder

[west eagle]

did you try vertice color

[brittle berry]

The effect would be visible with my custom shaders, otherwise it would render as a normal 3D file

Vertex colors are 3-channel, and 8-bits for channel

I want to store like 12 floats

[west eagle]

use texture then

several texture with same uv

[brittle berry]

Hmm I guess that's one way, if data no longer fits in UV

Thanks for the suggestion

[west eagle]

no problem👍

Hi everyone, I have a little problem but don't know how to solve it, I've made a shadergraph for VFX Additive particles, although everything is working there is always this annoying bug where if my texture touches the bottom of the image it creates these artefacts at the top of the material like in the picture.

In the texture that I've made, there is no white at the top of the texture.
It creates a lot of problems because it shows some artefact on the particles that I've made.

Does anyone have an idea of why this happens?

Here's my shadergraph

and the texture that I used

And this is the artifact that it causes

[meager pelican]

Unity supports 8 UV channels. Some are used for lighting though. (UV1 and UV2 IIRC). But that leaves you 6, x 2 = 12 floats. If you want.

[neat hamlet]

looks like the mipmaps are causing bleeding

clamp it

Hi, I have realized that the UV offset is not based off of percentage and moves less with larger sprites. 0.01 offset on a sprite thats 16x16 is nice but a 0.01 offset on a spriteSHEET that is 192x192 for example, is not nice
is there a way I can scale that uv offset proportional to the _MainTex size?

#💻┃code-beginner ask there, its not a shader question

Hey guys, how can I use a texture 2d array in the shader settings?

I have two texture 2d array and I'd like to lerp every texture at the same index (index 0 texture lerped with the second array, 1 of the first array lerped with the second etc.), but I'd like to not have a fixed index count, so I can't use an integer to manually lerp each texture of both arrays

is there a way to do that automatically? Like a foreach, but for shaders

[sturdy hawk]

I got this pig from the assets store, I can't add shadows to it, apparently the color is not added with a texture but with a shader... To fix this I'll have to code it my self, but it's the first time doing something like this

Shader "VertexColorFarmAnimals/VertexColorUnlit" {
Properties {
    _MainTex ("Texture", 2D) = "white" {}
}
 
Category {
    Tags { "Queue"="Geometry" }
    Lighting Off
    BindChannels {
        Bind "Color", color
        Bind "Vertex", vertex

    }

                combine primary 
            }

    }
}
}

this is what it looks like now... Can someone help?

[grand jolt]

hi

if ill instantiate a material, do i need to destroy it when closing scene?

[kind juniper]

You can pass the textures count as a parameter to your shader via script.🤔

[kind juniper]

Did you try using a default lit shader? They seem to be using vertex colors, so a default shader should work if you don't assign any textures.

[kind juniper]

No. It's gonna be destroyed on scene unload as any other unity object.

[sturdy hawk]

Can I add 2 shaders at the same time?

[kind juniper]

You can with an additional material. It might be messed up if your mesh has several meshes though. Why do you need 2 shaders though?

[sturdy hawk]

I'm just trying to understand how to modify that shader to have a basic lit shader that multiplies its base color with vertex color in it

but everything that I try makes my pig completely purple

[kind juniper]

That would happen if your shader is not compiled properly due to errors or is not compatible with the render pipeline.

But did you try what I suggested?

[summer shoal]

Hi, Im working on URP and want to know the easiest way to pixelize a color node, can someone lead me to the right direction on how to do this?

[fathom kiln]

I want to create a simple shader with stripes in shader graph. As a input I have the amount of stripes and the StripeWidth. A stripe should be at the beginning and at the end so its symmetrical.

[karmic hatch]

so you'd want it to go through (number of thick stripes * (width of thick stripes + width of thin stripes) + width of thin stripes) / (width of thick stripes + width of thin stripes) oscillations

rather than just (number of thick stripes) oscillations

so tiling -> (tiling + linewidth)?

[still skiff]

Hi! This is driving me insane: I have a shader property that I want to change during runtime. I do the exact same thing on a different object (player). Now when I do the same thing on an enemy mesh nothing happens. It is definitely the right shader. I pulled in the material via property like this:

    public class Health : MonoBehaviour
    {
        public int lifePoints;
        [SerializeField] private Material enemyMaterial; //<--

Then I pulled the same material into the Health component and into the actual enemy mesh. When I change the material's properties in the inspector the enemy material changes too, but when I do the same thing through code (in Health), then nothing happens. I already looked at some properties in Material and I'm positive I have the right one. The values also change, but the enemy still looks the same. Any clue where to look next?

[still skiff]

Oooof. When you click on a property in the shader graph it shows Name and Reference. For the player variable the Name and Reference coincidentally matched, so I didn't give it a second thought, but on my enemy the property "Darken" had the reference "_Darken". So I tried to set "Darken" and nothing happened, but it should have been "_Darken". At least I know nothing is broken. This might have been a useful information in "Using materials with C# scripts". 😦

Looks like an intellisense issue.

it is

only happened after putting the shader

Shouldn't prevent you from compiling the shader.

[lapis lodge]

the last part of Graphics.Blit
because dest is never set

it doesnt its weird

[autumn tapir]

@merry rose is there a way I can update to that version?

Check your Package Manager to see if there is an update for URP or Shader Graph, if there is none you will need to update to higher version of Unity

[proper plover]

thanks i'll look into it

[teal breach]

I found the issue. If you use the 'UsePass' hack to add extra passes to a shader graph shader, you must also make sure these passes have UnityPerMaterial buffers of exactly the same layout, otherwise carnage and hell

[proper plover]

sorry im stumped. How do i tile it seamlessly, i tried using object position as a uv and got this

[kind juniper]

Maybe triplanar mapping could work, otherwise it really depends on the uv of the sphere.🤔

[proper plover]

thanks i'll take a look! its the standard unity sphere 😦

[kind juniper]

Yeah, I think it's known to have bad uvs. It's not supposed to be used for anything more than a prototype.

[blissful yew]

Hey everyone. I tried to recreate the method from the famous "bleeding edge" video of using a sphere mask in world space -> converting it to UV space -> "baking" to a rendertexture that does not refresh in order to simulate "painting". However- I can't seem to get the render texture to not refresh itself? it keeps the projection un-smeared and its exactly the opposite of what i'm trying to do

this is how I write the RT. command is the commandbuffer. Maskmat is the material using the World to uv projection shader. I tried to use another RT(temp) to maybe see if itll fix the issue. It did not.

[lean abyss]

hey guys, apparently adding Stencil to my shader code blocks me from editing it's properties in runtime, does anyone know a way around this?

[ebon jetty]

anyone know why there'd be a difference between return -DensityTexture[coord]; and return -DensityTexture.SampleLevel(samplerDensityTexture, coord, 0);?

first one works, second one... doesn't, and I don't know why...

DensityTexture is defined like Texture3D<float> DensityTexture; SamplerState samplerDensityTexture; and coord is either an int3 or float3, but with the same values

I don't think anything weird is happening with casting from int to float because the [] one works even if coord is defined as a float3

(this is in a compute shader, btw, if you couldn't tell from my usage of samplelevel)

oh hell, it's because the range is 0-1 isn't it

[regal stag]

At a guess I'd say the first might be accessing based on 0 to width/height/depth, while SampleLevel would be using a 0-1 based uvs.

[ebon jetty]

lol thanks, I'm an idiot

that did it

alas, it did not solve my normals problem anyway

oh well

[meager pelican]

Things that are alpha-clipped aren't rendered. However, alpha clipping is pretty much done at the pixel level. So you still render the polygon (tri) and you still end up calling the pixel shader.

If you want to cull triangles, you'll need a different method than alpha-clipping pixels.

[meager pelican]

Other way around, you set a float value on the material via C# for the shader to use.

If you need to read a float from a shader (like a compute buffer in a shader) see ComputeBuffer.GetData

What is the value of _Big_WindAmount?
So far, you're getting either (_Big_WindAmount + 1) or (_Big_WindAmount - 0.0000001)

Well, you can have a shader that does that, but why?

The easiest way, if you don't mind doing it, is to "just" pass in the value you want from C# into the shader each frame. So pass in a pre-set _Big_WindAmount that cycles from 0 to 3 and back again.

Then you can inpsect it in C#.

OK, someone else will have to comment on terrain shader stuff, not me. 😉 Good luck with it though.

It doesn't. Your ifs are screwed up.

Unless o.worldPos isn't set for some reason.

The distance function works well (and correctly) in shaders.

[meager pelican]

Alright. Address the cycling first.
It sounds like you want a sin() wave but you need to shift the wave and scale it, because sin() goes negative for a portion of the curve. Maybe use _Time.y or something.
Or if you want a triangle instead of a curved path for the cycle, you can use something like
abs(frac(_Time.y*speed)-0.5)*magnitude

[feral mist]

hi all, I'm wondering if someone would know how to override the Default-UI shader. What I've done so far : recreated ui shader, named it UI-Default, name is UI/Default, I've put it in Resources, not seeing any results here.
Also swapped my new UI default shader and put it in always include ( but havent done a build to see if that would fix my issue.)

[teal breach]

I believe there's a way you can create a local copy of a package inside the project folder to override package specific things. I think it may have to have a specific folder structure though. Sorry this is extremely vague, I have never used it myself!

[calm rock]

Hey people, been a few years since I last tackled this problem in unity so I'm rusty and might not be aware of the current best practices:
transparency draw order issues in URP. I need to make sure this mesh gets drawn before that mesh within a single multi-mesh model and that multiple instances of that model are z-sorted correctly.
How can I best achieve this?
Also, I'm not seeing any way to control z-func stuff in URP (less/equal/greater etc). Is this an omission or something I'm missing?

[weak shadow]

Hey there!
I'm having some issues when sampling the normal GBuffer and writing to it in a shader. When just sampling it and writing it back i expect to see no difference in the result but when moving the cam i get kind of a solitaire effect^^ (gif).
When writing the normals of the mesh(lower pic) with the shader i get the desired results (upper pic).
My goal is to blend the mesh normals with the ones from the buffer.

Shader is pretty straight forward. Would be amazing to get some help with this ❤️

[calm rock]

At a guess I'd say your not clearing the z-buffer somehow? Looks like things are getting culled by a filled up z buffer to me.

[feral mist]

yeah that's actually when I initially tried doing, but that shader is not anywhere inside the package directory. Its one of those obfuscated default assets :/

[odd lichen]

How would one go about using an async compute buffer that needs it's output used by a normal shader as soon as available?

The output is a structured buffer of floats, and I don't want to readback to the cpu, but I don't know how else to tell the normal shader to start using new data when the compute is finished

[meager pelican]

Are you under the impression that variables in shaders keep their values between frames?

Not unless it is in a buffer of some kind.
You'll just keep getting the same value as set on the material each frame. You can add or subtract from that, but such is only in effect for that invocation in that frame.

Besides, it's massively parallel.

So each "core" (cpu) on the GPU is executing that code for all pixels. (or verts) being processed.

And each one would have its own local copy of that variable.

[molten violet]

Can anyone help me figure out why my dhader works on one scene but not in the other?

In orthographic, instead of using the A component of the Screen Position node, use the Position node set to View space, Split and Negate the Z axis.
And swap Scene Depth node (Eye mode) for this :

[meager pelican]

What pipeline are you using? @crude bolt

[crude bolt]

default

[meager pelican]

OK, so now I need to clarify what you mean.
What is the surface without doing your color mod? What do you mean by "brightness" of the surface? I mean, is lighting included or not?

Are you after some kind of two-tone "toon" effect?

[crude bolt]

a toon like effect

[crude bolt]

I just mean how exposed to light it is

I also don't want the light intensity or color to matter

just the direction

of 1 light

[meager pelican]

So you want a really simple toon shader.

[crude bolt]

yes

very very simple

[meager pelican]

OK are you using unity lighting? Like Surface shaders?

[crude bolt]

yes

[meager pelican]

It is often done with a gradient. If you want your gradient to "just" have two tones, fine. That will work.
That way, you can use Unity's gradient editor to edit the gradient in the inspector.
What happens is the shader computes the luminosity from 0 to 1, and then uses that as an index into the gradient.

[crude bolt]

gradient editor?

is it a shader graph thing?

oh u just mean the little thing u can edit in properties?

how would I get my shader to use that tho?

and how do I get info about how exposed to light it is

[meager pelican]

It's a unity inspector thing. See "gradient values" about 1/2 down this page:
https://docs.unity3d.com/Manual/EditingValueProperties.html

Alexander Ameye did a tutorial on a toon shader that might interest you:
https://alexanderameye.github.io/downloads/packages/shaders-done-quick/toon-shading.unitypackage

Basically, you can pass the gradient in as a small texture. Or there's ways to calc it.

Or if you just want to do what you said, and pass in two colors, you can do that too.

But I think you need to wrap your head around the luminosity calc first. IIRC, there's even a macro for it.
And you'll have to decide if you're using Surface Shaders and letting Unity calc lighting, or if you want to calc all that yourself.

There's some learning curve to shaders. But it's not that bad.

It just take some time. Because all things are new to you at once!

Luminosity is basically a math formula for how much red/green/blue value there is in the color. But the eye is more sensitive to green than it is to the others, so it is a weighted value.

Like I said, there's a macro for it somewhere. lol.
Let me see if I can find it.

fixed Luminance (fixed3 c)
https://docs.unity3d.com/Manual/SL-BuiltinFunctions.html

[crude bolt]

But then I will just get the brightness of the color of the object or texture pixel wont I?

Not with the lighting

[meager pelican]

Yeah, so you have to include lighting. See that example project. There's a couple of ways. You can calc it yourself, or you can generate a surface shader and go look at the code and see what it is doing for self lighting.

Then you'd take the color result for self-lighting, and use that and plug it into the luminance function call.
So you'd get a result between 0 and 1. Then you'd have a threshold, and decide on the color from there. Like:

half3 theColor = (lum >= threshold) ? color1 : color2;```

[crude bolt]

When I just take a standard shader it doesnt do anything with lighting tho

It just sets the metallic, glossiness and uv and stuff

And albedo

[meager pelican]

Lighting is a whole sub-system, basically. And those values play into in on a per-material basis.

The Surface Shader is a code generator. You "just" set a color on the pixel, and Unity generates a vert/frag shader from the surface shader WITH lighing code inserted for you automagically.

[crude bolt]

Oooh I see

[meager pelican]

There's a button in the inspector that will let you view the generated code for the shader if you have it selected. Warning, it may look intimidating since there's like 100 variants generated. But don't let that mess you up, just look at ONE of them.

[crude bolt]

Oh okay I see

[meager pelican]

What I don't know without trying it is if you can get around the auto generated code and decide on the color you want that way, or if you're going to have to do your own lighting calcs (which isn't that bad, and may be easier).

There is a "final color" thing.

[crude bolt]

Hmm okay

[meager pelican]

IIRC

[crude bolt]

I'll learn some basic shader cosing first as well

[meager pelican]

I'd just do it with my own lighting, and skip the surface shader. If I wanted to keep it simple. But you'll have to deal with shadows.

I'm not an expert on toon shading. Google is your friend, and there's probably 10 different approaches.

[crude bolt]

Alright

Thanks for all the help

Will try to figure it out now

[meager pelican]

See AA's project I linked above. I think he said something about using a simple Blinn-Phong lighting calc/model.

[crude bolt]

Will do

[steel notch]

So I'm trying to make a shader that allows me to add a Fresnel effect to a mesh and control it's opacity. For some reason however I can't seem to actually control the Alpha with this set up.

It's always the same amount
unless I set it to 0

[drifting salmon]

Change your blend mode to alpha, or whatever the default transparent blend mode is called, and see if the value works then. If it does, it's because the additive blend mode is ignoring alpha and you should just multiply your emission and color by your alpha value for the same effect.

[torpid hull]

You're missing an Add node between base colour and fresnal, also remove alpha node, unless youre using this for something else. Fresnal has alpha built in

[calm rock]

I asked this yesterday but perhaps it didn't get seen by anybody who knew the answer, so I'll try again 🙂
transparency draw order issues in URP. I need to make sure this mesh gets drawn before that mesh within a single multi-mesh model and that multiple instances of that model are z-sorted correctly.
How can I best achieve this?
Also, I'm not seeing any way to control z-func stuff in URP (less/equal/greater etc). Is this an omission or something I'm missing?

[steel notch]

Oh, hmm. Why exactly should the Fresnel be going into the Base Color, and not the Emission?

[torpid hull]

If you set your fresnal colour to HDR mode it will be emissive if you set the colour intentisy to higher than 1

[steel notch]

Alright thanks. I'll give it a try.

[tiny gale]

Are there any resources on creating shaders that work well with Augmented reality using ARFoundation / ARKit / ShaderLab

[torpid hull]

Also why are you spliting the RGB values of your base colour and them combining them back together? You could just add your base colour to fresnal and leave all that out?

[steel notch]

ya I was trying to split out the Alpha, it was dumb.

[raw pollen]

Hey guys, this is happening when building for WebGL, the models look fine in the windows version, do you know why this could be happening? Thanks!

[slender hinge]

Does anyone know how to accomplish something similar to https://videohive.net/item/pure-logo-reveal/30595492 or https://videohive.net/item/minimal-logo-reveal/31275848

[torpid hull]

Yeah but it would take me a few days to write how to do it.

[slender hinge]

It's not a rush but thanks! I was contemplating whether to purchase these and just display a video for the company's logo and stuff but I think I'd rather do it using the shaders of Unity. Also, I'm new to this server, when you're done, where do I find your post?

[torpid hull]

The shader stuff is pretty straight forward but theres a lot more thats happening to get to this effect, such as lighting, reflections, animation etc..

[torpid hull]

Is there a particlur one you want to copy? maybe I can point you in the direction of a few tutorials that might get you on your way?

[slender hinge]

Nothing in particular - I do like everything that is presented in the videos. You can pick one that you think would be the simplest and I can take it from there to recreate the other ones to try for myself. But the idea is to have the outline of the logo be the first to pop out, and then through the different animations and effects, the actual logo design gets revealed. Also, I'm not a fan on particles on logo reveals so you can leave that out. The simpler it is the better for me.

[slender hinge]

If I had to pick one or two, it would be from the first video on 0:08 and 0:36

[young ice]

Hi guys, any idea how to get the properties of a shader graph material and modify them?
It's applied to a UI Image and I'm using the following code to get the properties

string[] properties = image.material.GetTexturePropertyNames();
for (int i = 0; i < properties.Length; i++)
    Debug.Log(properties[i]);

As you can see in the image, the properties in shader graph are completely different from what it's finding.
The correct material is applied in the inspector.

[torpid hull]

I'll focus on the shaders, the animation and lighting is super simple. What I see is a base white shader with no reflections, transitioning to the colour (with no reflections) using a similar effect to a this https://www.youtube.com/watch?v=taMp1g1pBeE&t=527s and then bumping up the reflection on the colour. Maybe they've animated the reflection probe and possibly some lights, but this should get you started.

[slender hinge]

I've actually watched this before. And I've been watching a lot of Brackeys videos lately, a few of them about shaders. Thanks!

i have a shader A with a property X that I want to use in a pass that #includes another shader B file, where I actually want to use the property X. How do I get B to use the property X from A?

I tried defining the property float x in shader A, then #include the sahder B in a pass, then in the shader B file, declare the uniform with the same name as the property X, then use it in the frag function. Doesn't seem to work 😦 No errors though, its just not outputting the right value as I set a default value in the properties

Hello everyone, I want to make a wave round shader that will fade out. I wrote a vertex function, it creates a wave on a regular plane. Please tell me how I can generate circular waves with attenuation, using what I have already written. Thanks!

[molten violet]

I wan't to make a small outline for 3d objects and with HDR, are there any videos on how to make these?

[lapis lodge]

how can check if a number its even or odd in glsl?

[kind juniper]

With modulus operation same as in c#: %

[lapis lodge]

ive never used that

[kind juniper]

Then look it up. It basically returns the remainder of a division.

[lapis lodge]

ok thanks
now i have another question

how would i go about having 2 colors in a shader?

having each ball a color and not a mix

fixed4 frag(uint instance_id: SV_InstanceID) : SV_TARGET
      {
        //return the final color to be drawn on screen
        if(instance_id%2==0)
        {
            return _FirstColor;
        }
        else
        {
          return _SecoColor;
        }
      }

[kind juniper]

declare the second color as a property

Should be the same as for the first color.

[lapis lodge]

why?

[kind juniper]

wdym why?

[lapis lodge]

i think the problem is that im setting pixels and not the mesh

both colors are both set in inspector if that is what you are referring too

[kind juniper]

Doesn't matter. Assuming your instance_id is not messed up.

Could try passing the color from the vertex shader, but I don't think it makes any difference.

[lapis lodge]

here's what happens

[kind juniper]

Is that 1 object?

[lapis lodge]

yes is a procedural mesh acting as different

[kind juniper]

What if you have only one of these in the scene?

And share the whole shader code.

[lapis lodge]

doesnt matter

i use graphics.drawprocedural

[kind juniper]

What if you only draw 1 with that shader?

[lapis lodge]

same result

[kind juniper]

Share the code

[lapis lodge]

i will try to share the most important part, not sure if i should include the compute shader tho

[kind juniper]

probably not

just share the drawing shader

[kind juniper]

I'm not sure, but perhaps you need to initialize the instance data

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

[lapis lodge]

the inspector in this video shows the material

[kind juniper]

Not talking about the material, but the shader code.

[lapis lodge]

i think it needs to know where it belongs

if its part of a red, green sphere

[kind juniper]

That's what instance id is for. And it should be working as it is. My concern is that you don't have input structures in your shader. Donno if it's relevant though.

Since positions seems to work, I'd try passing the instance id from the vertex shader to the fragment shader.

[lapis lodge]

ok i think i can do that, but how should i declare the colors?

using another buffer for colors?

[kind juniper]

either get it in vertex shader and pass to the fragment shader in a structure, or pass the id in a structure and use the same logic as you do now.

[lapis lodge]

i have a question

so instance id

is a number that ranges from the the number of spheres to 0?

[kind juniper]

Each draw call with the shader should increment the id by 1 starting from 0

[lapis lodge]

so a for loop?

basically

[kind juniper]

for loop?🙃

[lapis lodge]

ok it was a bad example but like unity does
for(int i =0; i < numberofDrawCalls; i++)

i just thought they looked similar

[kind juniper]

yeah, something like that I guess.

[lapis lodge]

damn bro, best formatter

[lapis lodge]

so i changed the instance from the parameters and instead used in the if statement a uint called reer (im out of ideas), and well it's zero always

[kind juniper]

that's not what I meant.

Look at the examples on the docs page that I shared.

They use structs for input/output data:

struct appdata
            {
                float4 vertex : POSITION;
                UNITY_VERTEX_INPUT_INSTANCE_ID
            };

            struct v2f
            {
                float4 vertex : SV_POSITION;
                UNITY_VERTEX_INPUT_INSTANCE_ID // necessary only if you want to access instanced properties in fragment Shader.
            };

v2f vert(appdata v)
            {
                v2f o;

                UNITY_SETUP_INSTANCE_ID(v);
                UNITY_TRANSFER_INSTANCE_ID(v, o); // necessary only if you want to access instanced properties in the fragment Shader.

                o.vertex = UnityObjectToClipPos(v.vertex);
                return o;
            }

            fixed4 frag(v2f i) : SV_Target
            {
                UNITY_SETUP_INSTANCE_ID(i); // necessary only if any instanced properties are going to be accessed in the fragment Shader.
                return UNITY_ACCESS_INSTANCED_PROP(Props, _Color);
            }

instead of UNITY_VERTEX_INPUT_INSTANCE_ID you could define uint vertex_id: SV_VertexID in them and pass that to/from vertex to fragment shader.

[torpid sapphire]

Anyone knows why this is happening in my build ? A simple terrain shader is now taking 700mb at runtime. And all other shaders are taking a lot of memory. When i start the app the same shaders takes 1/10th of this size but it grows on my android build until it crashes. Im in urp and using addressables. Ever happened to anyone?

[kind juniper]

700 mb of storage or ram memory?

[wraith forge]

Anyone might know might be causing this problem on a custom shader? This doesn't have the same issue as the Standard shader

[vital smelt]

How do I get a reference to a mesh in a shader graph?

I want to make my flat plane mesh fade out towards the edges

[mental bone]

The position node gives you the positionnof each vertex

[grand jolt]

hello, when i try to get a depth texture, it returns a texture thats really lower resolution, and when i multiply it with an imported texture, we have a clash and the result doesnt work. my question is: how can i get a higher resolution scene depthe texture? (am working with shader graph)

[steel notch]

So I changed the graph to this and unfortunately I

1. can't control the transparency by messing with the base color's alpha
2. there's some serious layering issues within the models and between mutiple models that have this shader

[torpid hull]

Can you show me a picture of your model so I can see what is happening? Maybe I can see what it is your trying to do. Also will your model be effected by light

[steel notch]

sure give me a moment

so I have a model of a brain composed of multiple meshes

I want certain parts of the brain to glow when I hover over them with the mouse (the glow provided by the fresnel)

but I also want to be able to make certain parts transparent

here is the brain with the following shader

[torpid hull]

and it looks like you have a light source yes?

[steel notch]

yes

when I set it to transparent, parts quickly flicker in and out

as I rotate

[torpid hull]

give me a sec, just try to create the shader for you.

[steel notch]

with the fresnel producing a nice glow of certain regions

I just want to be able to... control the amount of transparency >_>

[vocal narwhal]

What happens when you create a float value and feed it into Alpha

[steel notch]

right so with this set up

[vocal narwhal]

Still doesn't work?

Oh, you're using additive

[steel notch]

with this setting

[vocal narwhal]

Just multiply the colour you're using by the alpha value

[steel notch]

alpha does sorta fade it out

is using additive a problem?

[vocal narwhal]

No, I just didn't notice that's what you'd chosen. Additive things can be faded out by just multiply colour by a value as black (0,0,0) will not add up to anything.

The issue with your flickering is just due to general transparency issues

[steel notch]

and how do I solve these "general transparency issues"

[vocal narwhal]

https://help.vertx.xyz/?page=graphics/models-and-materials/materials/rendering-issues/transparent-materials

[steel notch]

oh

alright thanks I'll take a look at this tomorrow morning

so I assume in the case of complicated meshes with lots of grooves and twists, that are also packed together with other meshes with similar grooves and twists, proper sorting with transparency can end up being a nightmare?

[vocal narwhal]

Definitely. Overlapping surfaces within a single mesh can be a pain to sort. Sorting between multiple transparent objects also has its pain.

[steel notch]

Oh so is that why additive looks so good?

It's just like "fuck it if there are overlapping surfaces just add them together"

no prioritizing anything

Oh anyone have resources for building an "intersection" shader? Like I move a mesh into some plane and "cut" into it, stopping it from displaying anything past the plane and leaving a nice cross-section

[vocal narwhal]

There's a bunch of ways to do it, I'd have to just google for resources.
I've done it with simple maths before, you can just use a dot product with directions made with the mesh position and a plane position against the plane normal to produce a +ve or -ve value you can use in alpha clip. If you don't understand that though I'd just find a tutorial 😄

Been getting these errors trying to build, any insight appreciated

[kind juniper]

What platform and what does your shader do?

[sterile sigil]

Unsure what platform means? But the error shows up for all shaders that have been made in Shader Graph

Up until recently everything worked and built. Not sure what I could have changed to break to

[kind juniper]

Platform like in Windows PC, Android, IOS, Webgl.

[sterile sigil]

Ahh sorry, Windows build target

[kind juniper]

Hmm

[sterile sigil]

I need to build for Mac as well, and in the past both of those would work. I’m thinking I must have changed something that messed up the subshaders?

[kind juniper]

Is that error thrown during the build process?

Or when running the build?

[sterile sigil]

It’s weird, it seems like the build finishes and immediately errors

I’m sending a screenshot because that DOS looking window scrolls very fast, I had to grab a screen quickly

But that black box is all that happens, no full screen build like previously

[kind juniper]

The build finishes successfully?

[sterile sigil]

It’s hard to tell but I think so

[kind juniper]

Then you could look it up in the editor log

nothing in the console, right?

@sterile sigil btw are you using a laptop? Do you have an integrated gpu?

@sterile sigiltry locating one of the shaders in the project and force compiling it.

[sterile sigil]

Stand-alone GPU. I will give that idea a shot, gonna have to look up how to do it

Thanks

[kind juniper]

in the shader inspector you can specify the target to compile the shaders for and then press compile and show code.

Do you want it to cast shadows or receive them?

Yes. These are 2 separate things afaik. To cast shadows you make another pass and render to the shadow mask/texture(or whatever you call it). Then you use that shadow texture in the regular pass(if I'm correct) to actually render the shadows cast on the current object.

you make it sound as if it's as simple as baking an egg. lol

might want to look into surface shaders as they simplify things a lot

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

Here seems to be a solution explaining how to do it with vertex + fragment shaders:
https://forum.unity.com/threads/adding-shadows-to-custom-shader-vert-frag.108612/

it's a struct passed from the vertex to the fragment shader

It's the same as

struct VertexOutput {
             float4 pos : SV_POSITION;
             float4 col : COLOR;
         };

In your shader

Just a different name

vert = vertex

it's a vertex shader

in your code vertex shader is:

VertexOutput vert(VertexInput v) {
             VertexOutput o;
             o.pos = UnityObjectToClipPos(v.v);
             o.col = v.color;
              
             return o;
         }

Ah, that was from your code. lol

Yeah.

yes

you can easily tell what shader is what by looking at the pragmas:

        #pragma vertex vert
        #pragma fragment frag

They actually tell the compiler what function is what shader.

Yes. In fact you need to multiply your color by that.

color * atten

and that should be your output

of the fragment shader

no, you don't have a variable called color

Do you understand what your fragment shader returns?

You don't need to make any variable. What does your fragment shader return?

Yes, you don't need. Answer my question first.

remove that line and the shader will compile

no

I'm asking if you understand what the fragment shader in your shader returns.

A function in programming can return a value.
I assume you know that?

[sterile sigil]

Ok, I got a better snippet of the errors. It's not confined to any one shader, which is making me think it might be a URP setup problem?

https://hatebin.com/jyhthnoiiy

[kind juniper]

Okay. It seems like you need to do some programming basics before you get to shaders...😅

[sterile sigil]

@grand jolt shaders and HSL are almost an entirely separate branch of development

[kind juniper]

You are not prepared!🍗

[sterile sigil]

you could learn to make World of Warcraft in Unity, including all databases and networking code, without learning shaders

[kind juniper]

for a full game

It's the same as in C#. You know what's a return of a function in C#, right?

Wdym?

there's a simple term in programming: return value of a function. If you don't know what it is, then you should go over a beginner scripting tutorial. C# would do.

[sterile sigil]

once again Unity and HSL are very different. Unity can't debug a shader

https://forum.unity.com/threads/debugging-shaders-in-visual-studio.322186/

that's how you can setup VSCode to debug a shader

if your goal is to make a cool shader for your game, I would suggest Shader Graph over learning how to write HSL. or alternatively, find some good starting point materials on the Asset Store and build off of those

[kind juniper]

You can't do that in a shader.

[sterile sigil]

^

am I muted or something?

[kind juniper]

It kinda looks like your GPU does not support anything at all. xD
