So the order maps to bytes, byte by byte, and then referenced by name.

So you have to keep them all the same so they match up.

[fresh moss]

ok

ill test it

still blue

[low lichen]

How far from 0,0,0 are you?

[fresh moss]

nvm there still not all alligned.

[manic arch]

0

The plane is at 0,0,0

[fresh moss]

YEA thank you verry mutch

it worked

[fresh moss]

i think i accidentally switched both

[meager pelican]

Happens. Can be hard to spot. 😉

2nd pair of eyes often helps.

[fresh moss]

thanks

[unique oar]

hey, sorry, how do I multiply a direction by a matrix in HLSL?? I've got a ray (written in local space) that's coming from an object, and i'd like to transform its direction using the object's rotation. i have access to its localToWorld matrix.

i tried just multiplying the direction by that matrix and subtracting the object position, but that didn't seem to yield the right value

[dim yoke]

I think mul(matrix, float4(direction, 0)) should work (*0, 1 is used for positions)

[unique oar]

ohhhhhh

omg that makes sense cuz the 1 is used to reposition the object

thank you so much!

oop

wait it's not working

[dim yoke]

You get error? It gives wrong value?

[unique oar]

oops im sorry, i was just multiplying in the wrong order :p

im still getting used to matrix operations

thank you!

[dim yoke]

[waxen citrus]

Good morning ! I would like to know how to ensure that the textures do not repeat when reducing the size of the texture. But I haven't found anything that really works with HDRP and shader graph. Any ideas ?

[grizzled bolt]

Use a Sampler State node to the texture to disable repeat

[waxen citrus]

Doesn't work... I always have the repeat

[waxen citrus]

in fact I need to repeat the texture but that we do not see repeating.

make it more natural

[grand jolt]

https://www.iquilezles.org/www/articles/texturerepetition/texturerepetition.htm

There are 3 different techniques here.

[grizzled bolt]

Ah why didn't you say so right away
https://blog.unity.com/technology/procedural-stochastic-texturing-in-unity here's one solution from unity

Do consider that there's a dozen different ways to do this, and it always depends on texture and location what's best

[waxen citrus]

Oh thx I check that

[grizzled bolt]

As explained there, uniform patterns cannot be tiled randomly as it breaks the pattern
In case of terrains you'll often be overlaying multiple textures and vegetation so the repeating will usually be hidden anyway

And in most situations it's enough to just author the textures in such a way that nothing sticks out and reveals the tiling

[waxen citrus]

ok ok thx you for your reply

[thorn tapir]

hey can I get an opinion on this water?
which looks better, the first 10 seconds or latter 10 seconds? (open original and switch to HD for best view)

https://gfycat.com/MiniatureEverlastingAssassinbug

Also, I want to both draw a hard edge along the top of top border of the water, and modify its shape through the shader it it does just looks flat, how would I go about doing this? I'm pretty new to shader graphs

[shrewd dome]

can someone help me please
how can i convert a shader from built in render pipeline to urp?

[grizzled bolt]

I prefer the calmer water version
Feels more at balance with the overall visuals

usually you'll want sharp and rapid motion for elements with visual importance

[grizzled bolt]

Unless it's one of Unity's default shaders, it can't be converted
You'd have to recreate its functionality using URP's shader format

[shrewd dome]

oke thx

[grand jolt]

What font is that?

looks sick

[thorn tapir]

The font is called CompassPro SDF

[grand jolt]

Oh its non commercial use

i found something similar tho

or the style at least

i forgot to tell that i like the first one more since it looks cleaner the 2nd one looks more chopped up or however you say it

[sharp carbon]

Where do I get to the shader graph for materials?

nvm shader graph wasn't installed

[thorn tapir]

it is for commercial use, and free
https://somepx.itch.io/humble-fonts-free

[grand jolt]

oh when i searched compasspro it lead me to some chinese site and thanks for even more cool fonts 🙂

[grand jolt]

bruh

how do i fix this

[meager pelican]

@half oysterI got some free time and played with that Brackey's 2D tut for fun.
It worked for me. I found that I can ignore the "smearing" on the sampler texture, as long as the result texture was OK.
The input format for the main sprite was a sprite texture. For the emission texture it was "default".
The result worked...I used the "walk1" sprite, didn't bother to set up a complete atlas. Nor did I mess with the "looks" too much, but here's the result.

[tepid agate]

Hi, I'm trying to implement a Jump Flooding Algorithm to a render texture but I noticed that the OnRenderTexture() function isn't working in URP. I would have to create a custom render pass to get the render texture I guess. But how do I update the OnRenderTexture() ? This is what I would like to get working -> https://unitylist.com/p/111b/Jump-Flooding-Algorithm

[tribal sky]

Hey,
I'm trying to make a shader, no idea what type... but what I need to do is this:
Triangle Visualisation with colouring.
For each triangle/quad/shape(?!): set a random colour for it.

Is it possible to do for a beginner? (PLease ping me!)

[low lichen]

Sure, this is doable. You can get the ID for the current triangle through SV_PrimitiveID and use that ID as the seed for a random function. Use that to generate a random color.

[meager pelican]

To this post ^^, I think it was due to having the alpha at 1. Assuming you have alpha set in your texture to 0 where transparent, you need that multiply or to split it off and put it to the alpha in the fragment stage.

[tepid agate]

Someone know why I get this error?

[tribal sky]

Thank you!
is that how you get all the triangles? and is it possible to just set it to a random colour?

[low lichen]

You would do this in the fragment/pixel shader. Use SV_PrimitiveID to determine what triangle the current pixel belongs to and use that to generate a random color

[clever saddle]

What is the meaning of id in the line "uint3 id : SV_DispatchThreadID" of compute shader

[kind juniper]

The ID of the thread

[silver zephyr]

im using the transparent cutout shader on this png but I just want it to overlay on the model instead of making it look see through.

theres this image on the back and you cant see either on either side

[clever saddle]

Then what's the xy here?

[vocal narwhal]

the x and y coordinates of the thread

[clever saddle]

Is the range of x and y fixed?

[vocal narwhal]

By the [numthreads(x, y, z)] iirc

[kind juniper]

I'm pretty sure that every tutorial on computer shaders explains that.🤔

[clever saddle]

It assigned the id.xy which is number of thread to the texture?

😖 Im confusing and mixed all them up

[kind juniper]

Not 100% sure, but I think that Id max value is a multiplier of threads count and thread groups count that you specify when dispatching the shader in c#.

Either way, all of that explained in most compute shader tutorials.

[clever saddle]

Here.Is the Id's xy is 7,5 or 27,13?

[tacit parcel]

You can play around with renderqueue, make the overlay render after the bottle
but if it's me, maybe I'll just blit the labels onto the bottle texture instead

[fluid inlet]

I came across this texture blending shader which blends been different materials depending on the height of the current fragment but i dont quite understand how this works ```c
_BlendSharpness ("Blend Sharpness", Range(0.06, 4)) = 0.75

[Space(30)]
_Layer1("Layer 1", 2D) = "white" {}
_Layer1Height("Layer 1 Height", Range(0, 20)) = 1
//...
struct blendingData {
float height;

float4 result;

};

blendingData BlendLayer(float4 layer, float layerHeight, blendingData bd)
{
bd.height = max(0, bd.height - layerHeight);
float t = min(1, bd.height * _BlendSharpness);
bd.result = lerp(bd.result, layer, t);

return bd;

}

[amber saffron]

From my understanding, the blendingData is a holder for "the current surface data", and you're supposed to call the BlenderLayer function in chain with as many layer as you have, passing each time the color through the layer parameter, and the height as layerHeight

[fluid inlet]

Ah ok! Thank you so much

[unique raven]

Anyone know why I can't pass a value from a split into the step node? Attached is a screenshot of my shadergraph, you can see that I'm clicking and dragging from the "G" channel on the middle "split" node, but none of the input options on the "step" node are active and won't take the input.

[dim yoke]

it seems Linear Blend Skinning works only on vertex stage. wouldn't you just use Position node? I think it should get interpolated to fragment shader correctly since you set the Linear Blend Skinning to Position input on vertex stage

[sleek kite]

Is it possible to write additional information into the shadow maps that unity generates? Or would I need to run an entirely custom shadowmapping system?

[low lichen]

What kind of additional information?

[sleek kite]

Basically I am faking 2D drop shadows by "propping up" sprites in the shadow caster pass, but this will obviously not work with shadow receivers, since the shadow is now "on top" of the sprite (even from the sprite itself, meaning I need to turn shadow receiving off, or all sprites self-shadow). My idea was to write the "height" of the sprite into the shadow map, and then sample that against the height of the sprite being rendered, to know if the sprite is actually shadowed. No idea if something like that could work, but that was my idea 🙂

The alternative is another entire pass similar to the shadow mapping pass, with a different fragment shader

[low lichen]

Can I see what this looks like? I'm having a hard time imagining this.

[tender remnant]

I'm doing a projected plane (to sync with where my ground plane stops rendering due to far distance in the camera) in my skybox through a custom shader. It looks perfectly fine in the editor view but in my game camera the fov seems to be misaligned with my skybox :/

anyone know anything about this issue?.., I'm rendering with urp

[sleek kite]

Something like this

I think maybe something that could be easier to combat the self-shadowing would be to check shadow occlusion in the "propped up" state, instead of laying down. Not sure how that would work though

I guess just passing the transformed vertex coordinates in addition to the actual ones to the fragment shader and then using those during lighting calculations could work 🤷

[low lichen]

Why fake it? Why not have the background/ground plane rotated so the shadow hits it the way you want?

[sleek kite]

I'm not sure what you mean?

[low lichen]

Or rather rotate just the ground in the shadow pass, the inverse of propping everything else up.

[sleek kite]

Wouldn't that change the light direction?

[low lichen]

You'd have to rotate the light as well, because right now the light is technically below the sprite, but above it when it's propped up.

[sleek kite]

I'm not sure how rotating the ground would do anything in the shadow pass, since the ground doesn't even cast a shadow

[low lichen]

You're right, it would have to be rotated for when it receives the shadow.

[sleek kite]

I think it still wouldn't work, but not because you're wrong

I have a lot of "sub sprites" that are part of the parent sprite (think rayman hands), that need to be offset so their "z-height" in the shadow is correct

Or maybe your approach would work regardless, I'd have to try it 🤷

It works fine the way it is atm though so I'll leave it as is

I'm gonna try passing the modified vertices to the fragment shader for lighting calculations, and see if that solves my problem, thanks @low lichen for bouncing ideas 👍

[low lichen]

Could you share some screenshots and relevant snippets from the shader?

[crude river]

Repost from general:
Hey so I am using unity 2020 2d and I was looking to create a toon shader for my game
I have no clue where to even start - my assets are 3d but I'm importing them in to look 2d. They aren't using toon shaders already as I wanted to create that dynamically
Does anyone know how I can do this? Thanks
I am happy to download one

[tender remnant]

Found the issue!

I made a stupid mistake.., I used a Position node in the shader graph instead of a view direction node. "Position" in a skybox apparently isn't behaving the same between game camera and editor camera.., which in hindsight makes some sense 🙂

[sleek kite]

Alright, that worked. Very happy I don't have to mess with unity's shadow mapping process after all 😅

[dusty coyote]

From UV I can get this gradiant-like line, is there anyway the same can be done with shape nodes, so the result would be the same shaped gradiant?

[trail hamlet]

Does anyone know in what folder compiled shaders are saved when running windows build?

[grand jolt]

Hello!
I've been following Sebastian League's tutorial about how to make an atmosphere shader but I'm completely lost, could anyone help me? I'm new into shaders

I'm trying to get this shader to work without being dependent on other scripts because I just want to make the atmosphere, not to copy all his code

[amber saffron]

Shape node draws a shape, not a gradient ... what are you trying to do here ?

[sleek kite]

Do shaders automatically strip code that isn't needed? e.g. can I have additional texture used by other functions in an HLSL file without a performance impact?

[low lichen]

Any code that is never reached is stripped out, yeah

[dusty coyote]

I want to get a black to white gradiant from the shape node. For example if I would use a Polygon shape node I could get a polygon shaped black to white gradient like in the lower part of the picture

In case of a Circle shape the result would be something like this

[amber saffron]

Sooo, basically, you want shape's distance field ?

[dusty coyote]

Yes, i think so yes.

[amber saffron]

There is no nodes for that, you'll have to build your own logic

[dusty coyote]

Mm, okay I'll try, thanks

[shadow locust]

looks like some Fresnel, no?

[dim yoke]

you can take a look at these if you want to get access to some basic shape distance functions https://iquilezles.org/www/articles/distfunctions2d/distfunctions2d.htm

[heavy stirrup]

anyone know of platform differences between android and windows that would affect heightmap displacements?

[cinder fiber]

Why's there no Pass block in the standard surface shader?

[dim yoke]

I think surface shader does that internally in the generated code. standard surface shader also contains 5 different passes so I don't know how that would be implemented in an easy way with Passes everywhere

[cinder fiber]

Thanks, got it

So surface shader is more abstract and is a combination of other shaders (vert, frag) under the hood, is that right?

[dim yoke]

the whole point of surface shader is that it allows you to write pbr shaders easily without having to be worried about different rendering paths, shadows etc.

[dim yoke]

surface shader is kinda like syntatic sugar for unity shaders that can interact with lighting. the shader code that is generated from the surface shader contains both vertex and fragment stages under the hood. so yes

[lyric oyster]

how do i find the y position of my water shaders thing in code, I plan to add boyancy using floater points(using Gerstner Waves by Zicore)

[grand jolt]

I think you can just compare the pixel's y position

[sterile wave]

how can i see trough object like this without using a a specific material for all objects that get transparent https://www.youtube.com/watch?v=S5gdvibmsV0

[grand jolt]

I'm pretty new to shaders too

[dim yoke]

can you just make the same calculation you make for each vertex on c# side to get the height on certain point

[lyric oyster]

hmm how do i do that with code tho
im quite new to shaders

[sterile wave]

mixing multiple cameras would be possible

[grand jolt]

So you have your input and output structs

First, in your input struct you need a float4 representing the position of a pixel, same thing in your output struct

Then, in the vertex function

[lyric oyster]

okay

[grand jolt]

You have to convert it to clip space

[lyric oyster]

that sounds complicated xD

[grand jolt]

Lemme write some quick code to show you

[lyric oyster]

alright thanks

[grand jolt]

{
    float4 pos : POSITION;
}

struct Output
{
    float4 pos : SV_POSITION;
}

In the vert function, you do this:
Output o;

o.pos = TransformObjectToHClip(i.pos.xyz);

return o;```

Something along these lines here

[grand jolt]

Np 😄
Is this your first time making shaders?

[grizzled bolt]

I think the most straightforward way would be to have the same wave function in C# code as is in the shader code, this way you don't have to mess with trying to get data from the shader to the CPU

[grand jolt]

I meant to reply to that

[lyric oyster]

yup

[grizzled bolt]

This is kinda tricky stuff to start with

[grand jolt]

Then you also have to do a bunch of other stuff for your shader to compile

Are you working in urp?

If that's the case you're gonna have to use hlsl

If you work in the built in pipeline, then cg

[lyric oyster]

im in hdrp

lol

[grand jolt]

Well, hdrp and urp both are a part of srp, templates to be precise

So hlsl is the way to go

[lyric oyster]

okay

[grand jolt]

Though you're gonna have to check out unity's github repo regarding the srp

Gimme a sec

https://github.com/Unity-Technologies/Graphics/tree/master/com.unity.render-pipelines.high-definition

Here, check the documentation folder

[lyric oyster]

This is the WaveDisplacement subgraph if it helps

[grand jolt]

Oh so you meant using shadergraph

[lyric oyster]

what od i do

[grand jolt]

I thought you wanted to write shader code

[lyric oyster]

um i mean thats the graph i need to get a position in code

[grand jolt]

You don't have to do any coding if you are already using shadergraph

[lyric oyster]

i have the graph, but i need a position in code to know the y so i can do boyancy physics

[grand jolt]

In shadergraph you can just add a position node and that's it

[lyric oyster]

yeah

[grand jolt]

What space do you want it in? ViewSpace, WorldSpace etc

If I'm not mistaken, the position node has an option for exactelly this

[lyric oyster]

not quite sure perhaps worldspace?

i could send the code but it aint letting me xD

for boyancy

[grand jolt]

I'm not that good at shaders yet to understand space modes in detail

[lyric oyster]

this is my code for the boyancy is there an easy way to just get the verexy or smth in there

[regal stag]

I think they are trying to obtain the positions on the C# side @grand jolt

@lyric oyster You could probably have another camera capturing the depth of the waves from above and use a AsyncGPUReadbackRequest, but reading data back from the GPU is slow so typically isn't done.
Replicating the displacement code on the C# side instead is another option. (Looks like two others have also mentioned this above but seem to have been ignored 🤷 )
e.g. The boat attack demo uses some C# Jobs stuff to handle their buoyancy implementation, but that's beyond my knowledge. https://github.com/Unity-Technologies/BoatAttack/tree/master/Packages/com.verasl.water-system

[lyric oyster]

found this on the tutorial im following(sadly theres no boyancy tutorial by this guy, but theres this comment)

[grand jolt]

I thought he meant hlsl side, since I didn't know he was using shadergraph

Also, for some reason I never noticed this:

It's actually quite helpful

[grizzled bolt]

I recall that using parallel wave algorithms for CPU/GPU is a common approach in these tutorials, but I don't have any at hand

[vale topaz]

Hey 👋
Question: Moving/Scrolling a texture in shader, wondering if it's possible to add some padding in shader to prevent immediate wrap around?

[lean lotus]

hey why is this

normalize(-float3(-1.0f, -1.0f, 0.0f));

different from this:

normalize(float3(1.0f, 1.0f, 0.0f));

?

oh I think the compiler is screwing with it
if I put it in this

((-float3(-1.0f, -1.0f, 1.0f)).x == 0.0f) ? normalize(-float3(-1.0f, -1.0f, 0.0f)) : normalize(-float3(-1.0f, -1.0f, 0.0f));

its perfectly fine

OK SO
compute shader

in this case
does NOT like it evaluating to -0.0f

so setting that to negative fixes it

alternatively setting that 0 to a very small non-zero number also works

[sterile wave]

is it possible to make a post processing toonshader?

[naive coral]

what does it mean when a function header is assigned a value?

[shadow locust]

why wouldn't it be different? Those vectors are pointing in different directions.

[lean lotus]

but the -float(-1) should be the same as float(1) right?

[spark ledge]

Well, I’m using Unity 2020.3.29f1, and I’m trying to work in the Shader Graph.
Weirdly enough I can’t seem to get the shader’s alpha to even function. Whenever I try to add the Alpha value, or node, to the base ‘fragment’ node, it’s just greyed out

Anyone know how to fix this?

[clear burrow]

Hello, I am trying to make my sight crosshair glow, and I am using a scope shader off the unity asset store, but im having trouble implementing the glow.

Here is my shader code:

https://pastebin.com/raw/sjrBsRkn

(sorry its a pastebin, it wouldnt let me put my code in here, itt said too many characters)

Im using the default render pipeline, and im on unity 2020.3.19f1

[weary osprey]

hey people! unity shader graph is doing this to a simple sprite glow shader im trying to make - thoughts?

this is what appears in game aswell!

[tepid agate]

what's the problem?

[weary osprey]

the sprite appears like that in game

[tepid agate]

isn't this what you want?

[weary osprey]

this is the original

sorry

[tepid agate]

Ah you mean the weird effect?

[weary osprey]

it is distorting / stretching the edges

yea

normally for tex2d thats normal as i understand

but my sprite renderers in game with it appear like that aswell

[tepid agate]

oof ok lol hmm

[shadow locust]

it's almost like... the uvs are being scaled or something

[tepid agate]

transparency is weird too

you should split the multiply node and make the "a" set to the alpha

[weary osprey]

okok

also this is the norm map if that helps w understading

never had this problem before

[tepid agate]

same xd

[weary osprey]

oh!@

you were right volt

thank you!~

[tepid agate]

it worked?

[weary osprey]

yea

did the trick

leme double check

[tepid agate]

it's like all right?

[weary osprey]

yea

[tepid agate]

wow great

[weary osprey]

lmao what the hell

[tepid agate]

now finish your game for me

[weary osprey]

ive never had that problem before tho

thats so weird

normally just rgb is the color and then alpha auto goes

maybe it was using red for the alpha?

[tepid agate]

you were setting the transparency to the red channel of your texture

[weary osprey]

^

yeeee

great minds think alike

tyty

[tepid agate]

xd now it's my time for my bug

[weary osprey]

i am very helpful when it comes to programming! not as much when it comes to shaders haha

ill do my best

[tepid agate]

Hi, I render a URP custom pass during the After Pre Passes rendering event to get a depth texture. After, I render a layer on the After Transparents event. The problem is that the shader graph doesn't have the pre passes texture. So the shader is replacing the texture with the current camera view. This only happens if the shader is rendered after transparents, not if it's rendered with the default renderer.

with the default render it's working

[clear burrow]

@tepid agate would you mind taking a look at the problem i’m having with my shader? (I’m not using shader graph)

[tepid agate]

I know nothing about shaders but I can. You want to add a glow effect or you already did but it's not working?

[grand jolt]

Hey, willing to pay somebody to help me merge 2 shaders

Because I have no idea how they work

I want to move the logic of one shader into the base of another

Because I only 1 blur shader that suits my needs but it’s blur logic is bad, and i just need to move this other shader’s blur logic into it

[tame topaz]

@grand jolt You can hire someone via the forums, #📖┃code-of-conduct

[grand jolt]

Oh crap

Sorry

Could i actually just post both shaders here and someone with basic knowledge could tell me what the difference is between them?

Might do a forum post

[tame topaz]

Yeah, you can ask any shader related questions here.

[toxic reef]

ello! I'm trying to use this cool portal effect from Sebastian Lague's video (https://www.youtube.com/watch?v=cWpFZbjtSQg), but in URP instead of built-in. One of his shaders, which I've attached, seems to be a surface shader, which URP just shows as pink, so I need to convert this to vertex-fragment it seems. I have zero knowledge on how shader code works for Unity, and no forum posts or guides I've found have been helpful to convert this code, can anybody help convert this? Would be extremely appreciated!

or i suppose a shader graph works as well, which I also have very little experience doing 😅

[sterile wave]

hey, i tried to use the camera scene depth with custom render feature and post processing, but all it does is blocking the whole camera view(also in editor). if you move the camera it changes the colors somehow. i tried 2 custom render features with different hlsl code but they both just blocking the camera. do i eed to change some settings?

[clear burrow]

I want to add a glow effect to this already existing scope shader

[misty plover]

Can TextMesh Pro SDF Shader's letters be used to mask a particle system such that the particles are only visible inside the letters?

Doesn't have to be particles that are masked. Just used that as an example because it's more complex than merely a static texture, which has workarounds whereby getting the masking effect with TMP doesn't require actual masking.

[sterile wave]

i think i dont need custom render feature since i can use "render Object"-render feature and then make use of the scene depth node in shadergraph to draw my outlines for specific objects

[tepid agate]

You could set the color to a more intense one and apply a post processing bloom

[clear burrow]

ah ok, Ill try that! the current color of that red is 255,0,0 so its as intense as it can go

[sterile wave]

i figured that it works, but i wonder about the basemap in the material since its not possible to set an object-related texture to the " render-objects"- material without a second camera and render texture/second shader with scene color node. it works with simple outline shader though... but does it even make a difference in terms of performance if use the shader in post processing/apply it directly to the objects material?

[clear burrow]

Ok so I tried to do the bloom method and Its not really giving the desired effect. What way could I go about doing this manually with shaders?

[paper pelican]

I was trying to make two custom nodes to get light data in URP but for some reason this function breaks the entire scene if the material using the shader is outside of the light range

{

#ifdef SHADERGRAPH_PREVIEW
    Direction = half3(1, 1, 0);
    Color = half3(1, 1, 1);
    Attenuation = 0;
#else
    Direction = half3(0, 0, 0);
    Color = half3(0, 0, 0);
    Attenuation = 0;

    int pixelLightCount = GetAdditionalLightsCount();
    for (int i = 0; i < pixelLightCount; ++i)
    {
        Light light = GetAdditionalLight(i, WorldPos);
        Direction += light.direction;
        Attenuation += light.distanceAttenuation * light.shadowAttenuation;
        Color += light.color;
    }
#endif
} ```

Anyone that could help me?

Nevermind

apparently the issue was that i was normalizing when in reality i meant to be saturating a dot product

😶

[amber saffron]

Normalizing a float value would result in either 1 or -1 I guess, while Saturate has a totally different effect 😄

[paper pelican]

Yeah it was totally my fault on that one 😂

[misty plover]

You have to build geometry to hold your blooms, which are textures additively blending with the background. You don't want to go this way. Play with the post processing. Push values harder than you think, and tweak madly. Bloom is not intuitive in Unity, at all.

[clear burrow]

Ok, I might just switch my project to URP and use a different scope shader ok the asset store lol

for 10 dollars it might just be more time efficient for me

[tepid agate]

What does it give? I really don’t know how to do it manually…

[clear burrow]

Its weird it doesnt glow but it does some weird outline effect

honestly its fine i was planning on switching to URP anyway

[misty plover]

in the long run, probably not. Generally, don't do bloom or any other effects and post processing until your game is done. And don't use anything from the asset store. Nor URP.

[clear burrow]

is URP not good or something?

Im going for a VR game so that why i thought URP might be best

[misty plover]

It's got lots of odd limitations, and foibles, and puts you into an update loop that's no fun at all, chasing bug fixes. BIRP is far better than it's given credit for, and there's masses of resources for shaders and post processing AND optimisations later on when you WILL need all that.

[clear burrow]

ok

thanks for the guidance 🙂

[misty plover]

You can always goto URP as the very last thing you do. But it's almost impossible to come back to Builtin. Also, iteration times with URP are much longer. Whilst making your game, remove ALL packages, so you can hit play and be in the game in 2 secs. Use 2019.4 Unity if you can. Build the game to feature complete, and only then worry about aesthetics and audio

On a n duration project, using this approach will likely save you a whole other n of time, so horrid are the problems with working "fully loaded" in Unity.

Hey folks,
I've got some more HDRP problems. I have a scene that's lit by one directional light and a volume containing a HDRI sky. The skin picks up the HDRI sky fine but they eyes don't appear to, also the shadow maps seem to be causing a jarring stipple pattern (this isn't caused by contact shadows).

without the HDRI sky:

without shadow maps or contact shadows:

What's causing that horrible stippling? It's not like shadow maps I'm used to.

and here's with the sun off but the HDRI sky on - eyeballs don't seem to believe in HDRI maps for some reason (this is using the 'eye' shader output in a HDRP shadergraph)

[calm rock]

I've fixed it but no idea how - in the shader I changed modes from 'eye' to 'lit' back and forth, removed a few redundant branches of the shader, plugged and unplugged some nodes and it started working. Not a lot of help sorry to anybody else facing similar issues :/

Hi, I render a URP custom pass during the After Pre Passes rendering event to get a depth texture. After, I render a layer on the After Transparents event. The problem is that the shader graph doesn't have the pre passes texture. So the shader is replacing the texture with the current camera view. This only happens if the shader is rendered after transparents, not if it's rendered with the default renderer.

This is working when the plane is rendered at the same time has other layers. But when the layer is rendered in an other pass, the texture is replaced

[lean lotus]

hey if two compute shader kernels share mostly the same data
is there a good way to run both at once?(they dont modify the same data, and could be completely seperate, while having relatively the same input data)

[heavy stirrup]

Does android re-encode textures? my textures are the wrong color now (HDR texture btw)

[wooden kite]

hi guys, can someone tell me how can i make a sprite shader that "blink" ? i've tried doing: grabbing the alpha from the texture, creating a color mask from the alpha, replacing color and multiplying/adding it, but it doesn't works

i wan't basically to replace the sprite color instead of adding/multiplying to it

here's how the shader currently is

when i try to pass the "Replace Color" directly into the Base Color it's supposed to be red (as the _MultiplyColor), but it goes to white

[meager pelican]

What do you want to do?
If you want the sprite to blink, change the transparency so it goes on/off or some degree of that.
If you want to tint it, make it white, and multiply it by the tint color.

[wooden kite]

i basically want the sprite to be able to blink with a solid color instead of just adding a overlayed color to it

however even after making a mask from the sprite and tinting this mask it is not working

[grand jolt]

You can just use multiply function to make it red

Replace Color have many instructions. It makes no sense to use it in this case, because you can simply multiply

Also you do not need ColorMask

Just multiply alpha with color and put it in Base Color

Try this

[grand jolt]

I am working on a shaded for my game. I need it to basically act like a skybox but with a screen door effect. I achieved the screen door effect through dither and it is working very well. however for the skybox I just made the base transparent and have a normal skybox in the scene . This wont work long-term however because I need to hide stuff behind the walls that the player cant see (I.e: Im going to have a tunnel and you can see it because its transparent) im not very good at shaders so how could i achieve a skybox effect that would keep the material opaque.

Here is my shader

this is the issue:

[lean lotus]

is there a good or fast way to get the inverse of worldToLocalMatrix in a compute shader? I dont want to have to send both worldToLocalMatrix and its inverse to the shader(lot more data sizewise would have to be sent then)

[tiny star]

Hi guys, I've been struggling with compute shaders hard for like a week straight now, and I need something super simple from someone who has the time so that I can learn since all examples I have found through google results can never give me a straight answer on this and I can't figure it out myself
could someone give me a compute shader where all it does is that takes in a Texture2D<float4> or RWTexture2D<float4> and then has some kind of buffer to output the exact same texture? also, could C# code to read and write the data to the compute shader be included?
I feel bad asking for someone to do this but I'm in a real rut here, no idea what to do after trying for a LONG time, this would be a big learning aid if someone could provide it

[tiny star]

heres the closest ive got in the last few days, but the output image is just a light grey square with random black/transparent parts and nothing like my original image
https://pastebin.com/rJF2jpwa
https://pastebin.com/QGCcinEX

this code was largely lifted from someone having a similar problem to me btw, not my code, but thats bc my solutions all gave extremely similar results anyway

[amber saffron]

Throwing some finding here :
You're using the load function in the compute shader to read it.
Load expects pixel coordinates, and since you're normalizing, your end up always sampling the first pixel eveywhere.
You either want to not normalize the coordinates, or use the sample function : https://gamedev.stackexchange.com/a/65853

[tiny star]

id like to not normalize the coordinates if possible, but im not sure how, since im honestly not too sure what id.xy represents

[amber saffron]

Secondly, you "copy" the texture using the compute shader, but this is all done on the GPU, the CPU doesn't have the data for writing in a file like you're trying to do. You will need to read back the data using Texte.ReadPixels : https://docs.unity3d.com/ScriptReference/Texture2D.ReadPixels.html

[tiny star]

i was under the assumption id.xy wasnt normalized this whole time so thats probably something thats been holding me back

[amber saffron]

id.xy is related to the dispatch semantic you used :

In your case, it maps to the pixel coordinate from 0 to texture size

[tiny star]

i really appreciate your help right now but its kind of going over my head, what would i have to do to get a pixel from the input texture2d using the id?

like, as far as i understand, with how manny thread groups im asking for, although in a random order, each group will represent one unique pixel in the input image

[amber saffron]

Ah sorry, I got confuse with the `float2 coordinates" line, but you're not using it.
So the load part should be working

Now, like I said, your need to fix the texture readback part on the cpu

[tiny star]

okie doke, so is the problem that using SetTexture() on the output and setting it to a rendertexture defined before this is not actually putting the texture data into that render texture, if that makes sense?

[amber saffron]

It does put the data into the render texture, but only on gpu side.
Where you do .GetPixels to write the file, the function can only access CPU data, that has not been initialized yet

[tiny star]

when written to file, the rendertexture used for output is converted to texture2d using this function, which uses readpixels, i dont think i use getpixels anywhere in my code
im not sure how i could "contact" the gpu version of the texture

[amber saffron]

On the other side, if you don't actually need an image file, you could just apply this texture at runtime on an object

[tiny star]

i need the code as is just so i can learn how to use compute shaders for something similar but on a larger scale, i tried the large scale thing first but faced similar issues to now so by scaling back and having the same p[roblem ive concluded i fundamentally am misunderstanding here

[amber saffron]

Ah, this wasn't in you paste code, but makes sense :/ it should work then

[tiny star]

would sending the output help you?

through all different methods ive tried for this concept (at least 3 or 4 total rewrites now), i ALWAYS get an output similar to this always featuring:

• mostly light grey/all light grey pixels
• random black bars

i got this result on both hardware at home and at my workplace

the size of the image is exactly right however

[tiny star]

also yeah, sorry, forgot that!

[amber saffron]

A first thing to try would be to apply outputTex to a quad in the scene with an unlit shader, you should then be able to see if it has the expected data

[tiny star]

okie doke, ill try that out, might take me a bit to program that but ill report back

yep, sadly applying the rendertexture directly to a quad with unlit/texture as it's material shader gives the same result

[amber saffron]

Hum.
And what about the texture after your resize step ? maybe it got "corrupted" at this point ?

[tiny star]

see, you might think so, but the actual beginnings of all this was to convert stuff that alrrady worked in C# to working in HLSL for much faster execution, all the functions used C#-wise are used elsewhere for image manipulation in my code without issue

unless theres some low level details of texture2d im not understanding here

[amber saffron]

An other way to optimize would have been to multithread the c# code using burst 😄

[tiny star]

i was taking advice from someone i met in industry, but i could look into that later today if this proves too taxing, as its rly starting to eat into dev time

[amber saffron]

Or, since you're only working with textures, using pixel shaders and blit commands (like always in programming, multiple solutions to do the same thing)

[tiny star]

im actually going to be working with WAYYY more than textures later on if the conversion were to start showing signs of functionality, so that wouldnt work for later, but thanks for the suggestion nonetheless

how hard is multithreading anyhow? i have no knowledge of it and id like to seriously consider it

[amber saffron]

I haven't done it myself for a while now, but using burst it's not so complicated, calling thread loops

But right now, except if it's the resize part before the compute that breaks the texture, I'm out of ideas :/

[tiny star]

alrighty, well thanks for stickin with me, always appreciate it, ill look into burst compiling now!

[tiny star]

update: totally understand multithreading, yeah its not too hard, tysm for the recommendation!

[grand jolt]

Is AlphaToMask an important feature?

What does it do and what does it look like with and without it?

[grand jolt]

Can anyone direct me to a list of what sort of textures unity uses? I've tried googling it and it seems its changed over the years and i don't kno wwhats relevant

[sterile spire]

Hey can anyone help me figure out this viewmodel shader I'm having troubles with?

[sterile spire]

https://forum.unity.com/threads/trying-to-write-viewmodel-shader-solutions-not-working.1253697/

Here's my post in the unity forums if anyone is able to help

[grand jolt]

Am I reading the documentation correctly that there's only:
Color map
Alpha channel
Normal map
for the textures?

[heavy stirrup]

hey guys

i set up my graphics api to use OpenGLES3

but renderdoc says Unity is using D3D11 api calls ... any thoughts?

VR

[amber saffron]

I don't understand the rood of your question : "what sort of textures"
Textures are images, imported into the engine and used for a lot a things.
What is the "real" question here ?

[grand jolt]

So in blender i'm used to working with:
Color map
roughness
Specular
normal
metallic

things like that

but i think unity only uses:

color
normal
alpha?

is that it?

[amber saffron]

OpenGLES3 is for mobile platforms (I guess Quest 1 or 2 for vr ?)
Unity editor on your PC will still run using directX/openGL/vulkan (depending on the windows api you've set) and will try to emulate the feature set of OpenGLES3 I guess

[grand jolt]

I'm trying to get an idea of what my limitations in texturing are

like what unity will render

[heavy stirrup]

I've set up OpenGLES3 on a separate unity project (without VR, but on Android platform) and it uses the correct api

[amber saffron]

No.
For the standard shader, Unity can use :

• albedo (color map) + alpha
• normal
• height
• metallic + specular
• detail albedo
• detail normal
• emission color

Like said, this is for the standard shader. You can do a shader that suits your needs and use a lot of different textures, like in blender you can customize the aspect of the material using nodes

[grand jolt]

oh ok cool ty

[amber saffron]

Then IDK

[kindred crystal]

i'm writing an image effect shader and struggling with depth normals -- for every frag, the normal seems to be (0,0,1) and the depth 0.5. anyone know why that might be?

some fragment shaders. this renders the depth texture as i'd expect:

float depth;
depth = DecodeFloatRG(tex2D(_CameraDepthTexture, i.uv));
depth = Linear01Depth(depth);
return fixed4(depth, depth, depth, 1.0f);

but with the depth normals enabled on the camera, this is all blue:

float  depth;
float3 normal;
DecodeDepthNormal(tex2D(_CameraDepthNormalsTexture, i.uv), depth, normal);
return fixed4(normal, 1.0f);

and this is all medium (0.5) gray:

float  depth;
float3 normal;
DecodeDepthNormal(tex2D(_CameraDepthNormalsTexture, i.uv), depth, normal);
return fixed4(depth, depth, depth, 1.0f);

i.uv is the interpolated uv coordinate from the vertex shader, same in each example

[kindred crystal]

guh -- ignore all of that, it was a problem (that i sadly don't understand) elsewhere. we have the camera in a prefab variant, and the camera has a post-processing volume / layer as well as the script for this effect. moving the volume/layer from the prefab (where they shouldn't have been) to the variant triggered something that fixed this issue. feels bad haha.

[devout spoke]

I am using unity_ObjectToWorld variable, but it's giving me an error saying to use macro UNITY_MATRIX_M instead. But looking at shader keywords I don't see just M, I see MV, MVP, VP, V, and P.

I tried just M, but it gives me the same error even though there I replaced unity_ObjectToWorld with UNITY_MATRIX_M

[kindred crystal]

looks like UNITY_MATRIX_M is defined in UnityShaderVariables.cginc (if you don't know where to look for these files they're in <path to your unity installation>/CGIncludes). should already be available if you #include "UnityCG.cginc".

never had your particular problem tho, can you screenshot the error?

[devout spoke]

I was injecting this HLSL into shader graph via custom function, it was throwing errors because even though I updated the shader script, the shader graph did not get that change. So it was throwing errors. I fully refresh, I had to setup the node again in shader graph, annoying but seems to work now.

Thanks for the tip though, it wasn't wasted 🙂

[kindred crystal]

cool, yeah seemed like it was probably an issue of stale state / errors

similar to what i imagine happened to me above 😅

[devout spoke]

What about this: error in 'Shader Graphs/GraphPointShader': l-value specifies const object at Assets/Shaders/GraphPointGPU.hlsl(11) (on d3d11)
Here is line 11:
UNITY_MATRIX_M = 0.0;

[kindred crystal]

if that line is in your shader, it means you can't assign to UNITY_MATRIX_M (that's what it means by l-value, the "left" side of an assignment)

because UNITY_MATRIX_M is an alias for unity_ObjectToWorld, which is declared as const somewhere (i couldn't find where)

what are you trying to do?

[devout spoke]

#archived-shaders message

[kindred crystal]

what’s the intention of that code?

[devout spoke]

Shader Custom Function

[devout spoke]

I basically need to overwrite the unity_ObjectToWorld per vertex. But it's throwing error saying to use UNITY_MATRIX_M instead, and when I do, it throws another error saying that left hand is a constant that can't be changed?

I need to reset the matrix to 0, and just inject my own position and scale into it and leave rotation at q.identity.

[regal stag]

Given that UNITY_MATRIX_M is a macro, you should be able to undefine (#undef UNITY_MATRIX_M) and then redefine it (#define UNITY_MATRIX_M someMatrix)

[devout spoke]

Originally I was attempting to use unity_ObjectToWorld and set matrix to that. Is that obsolete? Or did I setup it up wrong?

[regal stag]

It depends on the pipeline, I've done similar stuff in URP and used unity_ObjectToWorld without problems. But I would assume based on your previous error message that this is in HDRP.
It's not a pipeline that I'm very familiar with but looking at the ShaderLibrary code, unity_ObjectToWorld is still used in HDRP to pass the matrix in from Unity's CPU side, but it seems more of an internal thing - they don't want you to use it. UnityInstancing.hlsl only overrides the UNITY_MATRIX_M macro so that's what you're supposed to use. To prevent using unity_ObjectToWorld, another macro using the same keyword as the variable name is created with the value of Use_Macro_UNITY_MATRIX_M_instead_of_unity_ObjectToWorld (which isn't something that exists, hence it errors)
https://github.com/Unity-Technologies/Graphics/blob/018098f5a605f316f4828098fb616ecaf7052083/com.unity.render-pipelines.high-definition/Runtime/ShaderLibrary/ShaderVariables.hlsl#L518
Technically if you were to do #undef unity_ObjectToWorld it would likely then go back to allowing you to edit the actual matrix variable, but that seems a bit hackish. It would be a little better to redefine UNITY_MATRIX_M as that's what HDRP is already using.

[devout spoke]

Thank you for that explanation. Yes, you were correct to assume I was on HDRP, now that I skimmed through all the forums and got a feel for it, I am thinking it's a bad idea for me to dive into surface shaders and compute shaders using HDRP first. It's a shame, I gotten so used to HDRP lol.
I think I will just start with BRP just to get a feel for it and then see about porting manually to HDRP later on.

[patent lily]

hi, i wanna get my custom shader srp batcher compatible, but i get this warning "Builtin property found in another cbuffer than "UnityPerDraw"(unity_SpecCube0_HDR)"

[robust flame]

Hi everyone,
I'm beginner in Shaders and wonder if there is a way to do the opposite of this :

I want a sphere totally transparent and that become visible through a mask object.
But I'm not sure about the variables I need to modify

[frail seal]

anyone knows if theres some shader pack that supports line lights in legacy?

[amber saffron]

Maybe https://assetstore.unity.com/packages/vfx/shaders/alloy-physical-shader-framework-11978 ?

[frail seal]

it is sadly very outdated, with some custom importers throwing and inspector code broken

whatever, decided to drop good graphics, doesnt make sense anyway since the majority of the world is averaging on 960 for the foreseable future

[lean lotus]

So I have a compute shader, and that compute shader has a bunch of stuff in ifdef things, with defining the thing its looking for being a lot more costly(hence why it can be turned off)
But I want to be able to toggle between them on the fly during runtime, without the large performance impact that replacing the ifdef's with [branch]if(UseNEE) {} incurs
This value would be the same between all threads, and would only vary between dispatch calls
is there a way to do this?

wait nvm sorry
Turns out the bool defaulted to on when I told it to be off
simply turning it off manually works

[tulip crest]

Hi! I wanted to ask real quick what you guys would look for if you were looking for a tutorial for an effect similar to the shine of the interactable objects in vampyr
(video for reference: https://youtu.be/e1B_JS9_wjQ?t=63 )
or maybe someone knows what you'd use to make something along those lines
maybe use the shader graph? but I don't even know how to access that, I'm a complete noob with unity tbh

[past kraken]

can someone explain what are this white stripes

they are freaking me out

[regal stag]

The texture's "Wrap Mode" determines what happens when sampling with UV coordinates outside the texture's range. In this case it's set to Clamp, so it uses the same pixels as on the edge of the texture.
Can try padding the texture's edges with a transparent border if you don't want that. Or mask it using the Rectangle node.

[past kraken]

how to mask it?

[regal stag]

Probably with a multiply in this case

[past kraken]

thx

[grizzled bolt]

Probably best to shrink the star just a little bit in your image editor so the edges are clear

[tulip crest]

Okay I figured out some stuff myself

is there any way I could have a shader overlay over an already existing material as a sort of transparent glowy effect?
so for example I have this arcade machine and I have this (transparent) shader that I want to add as a sort of glowy effect on it (so you see you can interact with it)
how would I go about that?

[tulip crest]

okay so apparently I can have two materials on one object

so I tried to make a material with the shader but that kinda went fucko

it just kind of looks grey

even when applied to an object it still looks weird

[lean lotus]

if you do mul in a shader between a world_to_local matrix and a point, does it not translate the point?

[shadow locust]

It should

Assuming it was a world space point to begin with

You should get a local space point out

[lean lotus]

ok yeah was doing something wrong that works
new issue though
transforming normals from one object space to another

[shadow locust]

convert them first to world space (with localToWorld), then from world space to the new object's space (with worldToLocal)

[lean lotus]

so take the normal from the new object, multiply it by the origional objects localtoworld matrix(do I ever need to mess with an objects position? or does the matrix take care of offsets?), then multiply it by the new objects worldtolocal?(isnt worldtolocal the same as localtoworld.inverse?)

Oh also I then need to multiply it by a single matrix in shader representing the new objects space when it rotates

[past kraken]

Why does my color is semi transparent when I use lerp for blending textures?

[past kraken]

I just multiplied texture by rectangle and everything is fine

[fading stag]

is it allowed to ask modding related questions in here?

i dumped a prefab from a game that i want to reuse in the successor of that game (subnautica and below zero), but apparently the shaders got a bit messed up. im just not sure what exactly the problem is.
for example the external walls are transparent in unity editor (and also in game when i load the prefab). All i know is that others do not use the marmoset shader directly but instead use the default one and then change it in code.

[north raven]

[Unity 2D]
I've seen that we can use a render texture and use it as an ui to put a shader on the entire screen but is there a better way to do it than that ?

[lost canopy]

Hi. Is this the right place to ask questions about Compute Shaders?

[north raven]

I imagine so you can just post your question and hopefully someone will answer :)

[mental bone]

Do you mean a post processing effect ?

You can write custom ones for any pipeline

[north raven]

Yes but I want to use a shader as a post processing effect (I just use the render texture it's fine actually :)

(ok I just realised I'm replying while having no idea what I'm talking about)

[mental bone]

I dont understand what you mean. Slappin a render texture in a ui image or raw image wont act as a pp effect

For example bloom is a post process or screen distortion or color grading

[north raven]

by post processing you mean the one that's used with the post processing package ?

[mental bone]

Yes

[north raven]

I just need to look into how post processing works in general because it's probably really different than shaders

[mental bone]

Its not

Its still a shader

[north raven]

can I just apply the same shader that I add to normal objects to it ?

[mental bone]

No there are some specifics

[north raven]

Thank you for the informations :)

[mental bone]

There is documentation on the subject

[low lichen]

Yes

[lost canopy]

Fair enough, thanks. 🙂 I'm new to the server and wanted to make sure to at least respect the rules. I'm working on an AI project which has neural networks, and I was trying to use a compute shader to speed up the processing. Essentially I have a dataset as input (64x64 experiments 700bytes each) and network parameters (size varies but let's say up to one million floats). Each experiment is handled by a thread in the shader. They all compute the necessary adjustments to the network parameters for each experiment, in parallel. This works perfectly. But now I need to actually sum up the adjustments that each thread has calculated and add them to the network parameters and this is where I have no clue how to do that.

basically I have 64x64 threads that each spit out a 100.000 float buffer and I need the sum of that value (as in, the sum of each column, not everything together in one value, obviously). I don't know how to properly approach this.

[low lichen]

I'm not sure I understand. You say each thread spits out a float buffer. Do you mean you are creating 4096 compute buffers?

[lost canopy]

That is the problem. I have a 100k buffer that holds the network parameters. Each thread calculates 100k values that need to be added to the values of this buffer.

(100k floats)

but I have 4096 threads and I have one buffer, because I don't think 4096 buffers of 100k values is even possible.

The threads don't actually buffer those values, they just calculate them on the fly, but I need a way to properly sum them up in a way that is reliable (because I can't have them overwrite each other) and hopefully efficient. Blocking calls do exist, but they seem to only work for integers, and I need floats.

[low lichen]

@lost canopy I think groupshared memory can help with this, but I have personally never used it so I can't help with that much.

[lost canopy]

Thanks. I was just reading into it. I might have to dedicate some threads to just performing the additions, and maybe I can use groupshared memory to do that somehow. I will try and make it work. Thanks for the assistance

[low lichen]

@lost canopy Out of curiosity, have you already considered or used C# Jobs + Burst for this?

[lost canopy]

I had not. Definitely worth looking into, although at this point I'm dedicated to making this work 🙂

I have the whole thing working in c# so I am definitely taking some time later to see if I can speed it up that way.

[low lichen]

Compute shaders will definitely be faster if you can adapt the problem to that architecture, but it will also always take some time to copy the results back to the CPU, something C# Jobs do not suffer from.

[lost canopy]

It's a really good idea.

I might even implement that straight away because I do need a break HLSL at this point I think... I know c#. I understand how it works, kind of. With HLSL I feel lost anyway because of how different and unfamiliar it all is. I really appreciate your help, thanks again!

[versed iris]

for some reason, when I import materials from blender, they get really dark... this is supposed to be green. Any suggestions?

this happens for some models and not for others, it's really strange

[lost canopy]

I had similar experiences with importing from Blender. Some models would work and others had inverted normals etc. I wish I had a solution for you, but I only remember my artist messing with the model until it worked in Unity. Sorry.

[versed iris]

any idea what he did?

[lost canopy]

Sorry 😦 I take it you've tried different formats for exporting?

[versed iris]

yes, it still ends up beeing really dark

i guess I'm reasonably early in my project so if nothing works, i should be able to just copy-paste my assets into a different one

[median turret]

Why does it disappear at some point?

[regal stag]

Dragging a colour (RGBA, Vector4) into the Alpha port which is a Vector1/Float will truncate the vector, taking only the first channel (R). You likely want to use the output before multiplying by the colour. Or use a Split node to obtain the A channel (or Swizzle with "a")

[median turret]

Thanks!

[lost canopy]

Is there any way for me to see when my compute shader has finished executing so I can retrieve the data?

I mean I could have each thread set a buffer value to 1 when it's done and then keep testing whether it's all 1's now, but it feels like there should be a better way.

[low lichen]

You can either call GetData on the buffer, which will pause your script at that point until the compute shader has finished or you can use AsyncGPUReadback:
https://docs.unity3d.com/ScriptReference/Rendering.AsyncGPUReadback.html

[lost canopy]

oh, so basically I can immediately read the buffer once I've called shader.Dispatch(..) ? That will halt execution on my script until the shader has finished?

(sorry if that seems basic, I am new at this)

[low lichen]

Yes. If you want the result as soon as possible, that's what you should do. But if you don't want the game to freeze, you need to use async readback.

[lost canopy]

I understand now. Thanks so much for the help. Shader documentation is ... rudimentary at best.

[lament scarab]

How could I use this as normal material on a surface?
It shows as a skybox even if I put it on an object. I'd like the texture to be just the sky part.

https://github.com/n-yoda/unity-skybox-shaders/blob/master/Assets/SkyboxShaders/Skybox-StarrySky.shader

[tiny shuttle]

Is there a way to remove the mirrored bottom part without changing the UV

Like , adding a black color on the bottom half of the sphere to cover it

[low lichen]

Sure. If you assume the mesh has its pivot centered, you can assume all pixels with an object position Y below zero are part of the bottom half.

[tiny shuttle]

i am a beginner and idk which nodes to tackle

But yes the pivot is centered

[low lichen]

The simplest way would be to use the branch node

[tiny shuttle]

So if branch is just true or false how to add the logic ?

[dim yoke]

Use position node (object space) > split y component out of it > use compare node to get whether it’s positive or negative > use that in branch node

[tiny shuttle]

Damn it actually worked thanks alot guys , now i will figure out how to gradient for fog effect

[versed iris]

i think i found the problem, i had to change the color space from linear back to gamma, to then reimport the model... pain

[lost canopy]

Well I'm glad you could fix it.

[amber canyon]

im using an asset to do some kind of teleporting effect and it requires i use it's shader. but the shader loses a lot of detail as you can see on the model on the right vs the left. what can i do about this so i can use the effect but also not have the model look bad?

https://streamable.com/x7yeej i tried swapping out the materials for when i need the effect but it doesnt look very good

[opaque garden]

guys what shader type i should use with trail renderer

[lavish stream]

does anyone know of any implementation of runtime virtual textures being used to blend objects and foliage into the terrain? this is trivial in unreal engine, so i wonder if there's any 3rd party tool that lets you do this
(i've looked into microsplat, and found it to only work with the most simple of terrain shaders)

[soft jacinth]

I would say microsplat is one of the most advanced terrain shaders out there actually.. though you would need a lot of modules to get the full package it's a popular choice as a base for many regardless.

found it to only work with the most simple of terrain shaders
What exactly is it you need microsplat to work with?

[gleaming pagoda]

would anyone know of an "underwater" shader

or any ideas to replicate being underwater

[soft jacinth]

post processing is what you're after I think. #💥┃post-processing

aka camera effects.

[gleaming pagoda]

thanks

[lament scarab]

How could I use this as normal material on a surface?
It shows as a skybox even if I put it on an object. I'd like the texture to be just the sky part.
Seems like Unity does something, or maybe an instruciton in the shader that makes it be used as a skybox?
https://github.com/n-yoda/unity-skybox-shaders/blob/master/Assets/SkyboxShaders/Skybox-StarrySky.shader

So I found out Skybox in the name and the tag, is part of it, but even after changing that I still get this when it's placed on a quad, how would I remove the bottom part so it's just the top part?

I think just removing the horizon would do it, but I'm not sure how to do that.

[meager pelican]

https://levelup.gitconnected.com/fun-with-skyboxes-dd28ebaef48c

Just use the stock cubemap shader.

[lament scarab]

But then it uses an image/texture, not the shader.. :/

[grizzled bolt]

You could bake the sky into a cubemap texture

[lament scarab]

I just think that it one line somewhere in the shader code that I need to change.. I'm just so unfamiliar with shader code, tried commenting a few things but no success yet

cause like, it's something the shader does that creates the horizon/terrain/ground thing

and i'm just trying to have it render whole kinda

what i'm saying is. i think even if I bake it, it will still have the horizon?

[grizzled bolt]

Well, yes but if you want to get rid of all the procedural sky features, why would you use the shader in the first place? It would be much easier to find a cubemap of just the stars

[meager pelican]

Which is what I gave him...no horizon.
GPU's are optimized for texture reads...and the cubemap is optimized

[grizzled bolt]

Indeed

[meager pelican]

But if he wants it as an exercise, he needs to rip the horizon code out of whatever shader. But that's him programming. There's a number of ways to do it in a shader, but it probably ends up slower unless you need something special.

[lament scarab]

But it uses a texture, the shader places stars programatically, it's not the same end result

and the amount of stars, their position, the density, etc, can be changed

[lament scarab]

not getting rid of them!

probably worded it wrong

but it's just the non-sky part i want to remove, the grey part

[meager pelican]

https://github.com/PopThosePringles/Unity-Procedural-Skybox-Shader-No-Horizon

Haven't tried it.

[lament scarab]

yeah that's a start for sure

seems like they removed a lot tho

if that's what it started from:

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

if I look back at the first github i coded, it's still unclear what i would need to remove comparing theses two

kinda checks out tho.. shader stuff's always hard

[grand jolt]

Hello. How can I make it so that when light.distanceAttenuation hits the mask (a certain area), the entire object is painted over in a solid color. The closer the light.distanceAttenuation is to the area, the stronger the color.

[runic girder]

Anybody know how the data for meshing a texture is typically saved when compiled? the triangles' position and vertex thing

[last dust]

does anyone know a good cartoon shader tutorial that isnt outdated?

[dim yoke]

What compilation are you talking about and what you mean by ”meshing a texture”?

[runic girder]

I was trying to find where a game saves that info after it's compiled / built / exported whatever you call it

and the texture is reduced to it's shape like cropping while shown in game, when the texture file itself is rectangular

[steel cave]

i bet one of your shaders is specular and one is roughness. so like your default shader is able to take your maps correctly and apply the coloring, but i wonder if your dissolve shader is setup with a different pipeline for your textures. I had something similar happen where i was using a shader for amplify that was setup to do specular and i was doing metallic roughness so i had to unconnect some of the nodes and reconnect some nodes for my own textures (which required me to have amplify to edit the shader). so if you are running shader graph / or amplify or whatever and you can edit your shader i'd check to see what it is... also.. there are other free uber shaders for unity that do dissolve / fade / rim lighting / emissions / decals / etc etc etc.. so if you can't get it going i'd swap to one of those shaders

[arctic flame]

what do i need to do to get the alpha value on my trail renderer reflected in the displayed material?

[coral tide]

what does this mean?

Shader error in '[System 1]Initialize Particle': failed to open source file: 'Packages/com.unity.render-pipelines.high-definition/Runtime/VFXGraph/Shaders/VFXDefines.hlsl' at kernel CSMain at quads-Circle.vfx(19) (on d3d11)

[dim yoke]

I don’t know but I’m just wondering what you need that for?

[teal breach]

Is it possible to make a shader as always included in the build from the shader file? Or is the only route to use the project settings?

I have a bunch of post process shaders which get excluded from the build, would be nice if I could mark the asset itself as something to include

[covert patrol]

Hi, could anyone help me with a problem im having with shader graph?

its a problem with my player sprite/material. whenever I make a material from an Unlit Shader Graph and assign it to my player, instead of being an empty white square it deforms the sprite into a weird deformed shape. when I add a Texture2D to the shader graph it shows the correct player sprite but only in that same deformed shape.

[grizzled bolt]

What kind of "deformed shape"?

[covert patrol]

this is the original

[grizzled bolt]

Looks like this is the sprite outline

Which is revealed when it's not rendered transparently

If you look at your usual sprites in wireframe mode you should see their outlines too, if they have them defined

[covert patrol]

oh yeah i see it

so i have to manually change that?

[grizzled bolt]

My understanding is that sprites shouldn't have outlines unless you have manually created them
The default shape should be a rectangle

Dunno if there is a way to reset them without importing the sprite sheet again, or a way to generate multiple at once

[regal stag]

It depends on the "Mesh Type" when importing the sprite. When set to Tight, unity generates a shape like that so there is less overdraw when rendering. You can set it to "Full Rect" to force it to a rectangle if required.

[regal stag]

You likely need to change the graph surface mode to Transparent (in Graph Settings tab of Graph Inspector window). Possibly also just change the type to the Sprite Unlit.
Then can connect the A output from the texture sample to the Alpha port that appears.

[covert patrol]

oh okay, ill try that right now

[regal stag]

Same as the colour itself, it's passed into the Vertex Colors of the mesh. Split/Swizzle it to obtain the alpha component and multiply it with the current alpha value

[covert patrol]

unfortunately my problem is still there :(

the texture becomes distorted like in the picture

one thing that might cause the problem is that my sprite sheet has a lot of white space, but im not sure

[regal stag]

The previews in Shader Graph don't show transparent areas, just the RGB data which tends to spread out to avoid artifacts along the transparent edge. But as long as the alpha is connected, it should still look correct in the Main Preview (bottom right) and scene view (but make sure you click Save Asset in the top left)
You may want to connect the RGBA output to the Base Color port too.

[grizzled bolt]

Full Rect in sprite import settings as Cyan mentioned should stop the "deformation"

[covert patrol]

wait omg i think it worked

the rect thing definitely stopped the deformation

let me check the shader

[regal stag]

Yeah though not sure if that setting shows up for sprite sheets, I don't work in 2D often. You shouldn't need to change the outline/mesh shape anyway though, it's meant to be like that to reduce overdraw. As long as you use the alpha channel you shouldn't see it

[covert patrol]

oh yeah, it doesnt deform when i put it back to tight

ok i think that fully fixed it, thank you so much cyan and spazi

[rustic adder]

hey so i made a cloud shader for my game that i want to be visible far into the distance but at the same time i need to keep my far clipping plane for the player pretty low so that it doesnt lag the game

so is there any way to have a high far clip just for the clouds but a smaller value for everything else?

[meager pelican]

It's an attribute of the camera. You could try camera stacking, with your first camera just drawing a background but you'll lose optimizations, since the skybox is usually drawn AFTER opaque stuff to avoid drawing unnecessary pixels.

[rustic adder]

i tried to stack the camera but since the main camera is attached to the player, the entire cloud system starts moving with the player

this is my current camera setup

at the bottom i added a CloudsCamera just for the clouds but everytime i put it as an overlay to the main camera the clouds follow the player @meager pelican

[meager pelican]

IDK what to tell you, other than have your cloud shader compute some logical world-space offset so it doesn't move relative to the camera.

[thorn tapir]

hey so I made this shader.... but I'm struggling to figure out how to get it into my 2D scene... also the main preview is blank and I'm not sure what to do about that... if I change it to just an Unlit Master, it shows up in the preview, but thats not exactly what I want for 2d, I dont think?

https://i.imgur.com/y9nu4Yk.png

https://gfycat.com/QuerulousSinfulHammerkop

its going to be pixelated later by my pixel perfect camera... but.... yea, how do I actually get this animating like this in the scene?

[regal stag]

The alpha channel here is likely completely transparent (0) which is why the main preview is blank.
It's a bit easier to work with the "Sprite Unlit" type in v10+ as the newer master stack splits it into the Color(3) and Alpha(1) ports like the regular "Unlit" has. But for the older master node versions like this you can use a Split node, then recombine the RGB channels using a Combine or Vector4 node, with the A channel set to the output of your One Minus node.

[thorn tapir]

oh woops, you right about the alpha part, fixed that

multiplying seems to work just fine

the one minus and the add multiplied into the split unlit master color I mean

anyhow, the problem still persists

I dont knwo how to get it to show up in my scene

I have it applied as the material for a sprite renderer, but its just... nothing

god dammit found the issue...

[regal stag]

Well the Sprite Lit/Unlit types are mostly designed for the 2D Renderer. I can't remember if the generated shader has regular forward passes so it might not work if you're using URP's Forward Renderer

[thorn tapir]

the alpha was set to 0 in the material window

even though I set the defaults to 255

[regal stag]

Ah okay

[thorn tapir]

sweet, got it working...
https://gfycat.com/GlitteringScarceAfricangroundhornbill

now do I leave it like that? or pixelate it...
https://gfycat.com/VigilantCorruptDunlin

[thorn tapir]

dear unity devs: WHY are new colors in the shader graph assigned alpha 0 by default

[shadow locust]

because they're 0,0,0,0 by default

probably because float4 in HLSL is (0,0,0,0) by default

[prime umbra]

Hello, I am wondering how to input a shader to a texture

I'm trying to add it to this worm

[grand jolt]

How do you calculate normals after vertex displacement?

[slow sleet]

Hello! i need help!
been trying to make a shader that would show a selected unit with a green square around it, using projector-something
i did what tutorial told me but im getting my shader cast over the whole terrain rather than just around the tank
and i dont know what i did wrong here is the shader code

Shader "Projector/Multiply" {
    Properties {
        _Color ("Main Color", Color) = (1,0.5,0.5,1)
        _ShadowTex ("Cookie", 2D) = "" { TexGen ObjectLinear }

[drowsy linden]

How would I be able to make a shader where a single object is rendered one way in one camera but another way in a second camera

[steep creek]

is there a way i can access float arrays from shader graphs? It seems really weird that this exists SetFloatArray if i can't access the array

[steep creek]

for some reason if i do #include "unityCG.cginc" i get a redefinition of _Time error, if i delete the include i get an undeclared identifier UNITY_SAMPLE_TEX2DARRAY error, what do i do?

[soft jacinth]

I'm painting these cubes based on vertex color of their position fed by noise; so there is a sort of gradient happening but the issue is it's too dark.. I'd like to take the darker vertex colors and paint balance/saturated even hue shift.. any useful nodes or tips on something like this you guys know of?

[regal stag]

You can use float arrays in a custom function node (file mode), I have an example here. https://www.cyanilux.com/tutorials/intro-to-shader-graph/#arrays

[steep creek]

i fugured that out already the current problem is the sample function, it just doesn't want to work

[regal stag]

Use SAMPLE_TEXTURE2D_ARRAY(textureName, samplerName, coord2, index) instead

[steep creek]

that's what i have currently but this, i have no idea what those even mean

yes it's sebastian terrain generation shader

[regal stag]

In short it means you have the incorrect number of arguments/inputs, or they are the wrong type

[steep creek]

    float3 scaledWorldPos = worldPos / scale;
    float3 xProjection = SAMPLE_TEXTURE2D_ARRAY(_baseTextures, ss, float2(scaledWorldPos.y, scaledWorldPos.z), textureIndex) * blendAxes.x;
    float3 yProjection = SAMPLE_TEXTURE2D_ARRAY(_baseTextures, ss, float2(scaledWorldPos.x, scaledWorldPos.z), textureIndex) * blendAxes.y;
    float3 zProjection = SAMPLE_TEXTURE2D_ARRAY(_baseTextures, ss, float2(scaledWorldPos.x, scaledWorldPos.y), textureIndex) * blendAxes.z;
    return xProjection + yProjection + zProjection;
}```

is 4 args wrong?

everywhere i looked it said 4 args is right

it was telling me that SamplerState was wrong so i switched it over to UnitySamplerState

[regal stag]

Hmm it might be the ss input. Try ss.samplerstate instead

Or might be able to do _baseTextures.samplerstate to use the one from the texture. That might only be if you pass the texture into the function though (as UnityTexture2D).

[steep creek]

now it says cannot implicitly convert from 'float3' to 'struct UnitySamplerState'

shaders are such a pain

there is one thing i can't understand why is it saying that the error is on a random line that isn't even in the code?

like 300 something while the code is only 90ish lines long

[regal stag]

It's likely the line from the actual generated shader, not just the include file

[steep creek]

generated code is 274 lines long

or is there an even deeper generated code

that you can't access

[regal stag]

Maybe, not sure. I've also found the line numbers not that helpful so tend to ignore it

[steep creek]

        float3 triplanaredTexture2 = triplanar(worldPos, _baseTextureScales[layerCount - 1], blendAxes, SS.samplerstate, layerCount - 1);``` here are lines calling the function

i don't think i did any mistake here but still

[regal stag]

Looks okay to me. The error might just be pointing to the function

[steep creek]

the material preview is doing weird stuff

[regal stag]

Can you post the updated function code?

[steep creek]

    float3 scaledWorldPos = worldPos / scale;
    float3 xProjection = SAMPLE_TEXTURE2D_ARRAY(_baseTextures, ss, float2(scaledWorldPos.y, scaledWorldPos.z), textureIndex) * blendAxes.x;
    float3 yProjection = SAMPLE_TEXTURE2D_ARRAY(_baseTextures, ss, float2(scaledWorldPos.x, scaledWorldPos.z), textureIndex) * blendAxes.y;
    float3 zProjection = SAMPLE_TEXTURE2D_ARRAY(_baseTextures, ss, float2(scaledWorldPos.x, scaledWorldPos.y), textureIndex) * blendAxes.z;
    return xProjection + yProjection + zProjection;
}```

i moved the .samplerstate to the calling lines

it started running now!

but it does this which isn't really better

but still something

also it's not static it acts like a noise randomly changing

[regal stag]

If you're using Shader Graph, there are nodes like Hue, Contrast, Saturation (not to be confused with Saturate), or Colorspace Conversion to convert to HSV where you can hue-shift / adjust saturation then convert back to RGB/Linear with another Colorspace Conversion.

[soft jacinth]

thanks! noticed the saturated node, I will start messing with all that now.

[regal stag]

If it's just a single object it would likely be easiest to duplicate the object, change it's material and then have both on different layers and set the culling mask on the cameras to only include the one that should render.

[steep creek]

so i had to regenerate the mesh so the meshGenerator script sent the material data over and now i got this... it only draws the rocky part it seems and nothing else

[primal harness]

Does anyone have any information on how to write custom shaders that work correctly with depth priming? (in URP)

[teal breach]

I thought, perhaps naively, that it should work out of the box if you don't use a SV_DEPTH output?

[calm rock]

Hey all,
In HDRP's hair shader, there's an input for 'Hair Strand Direction' which is used in Anisotropic shading. Is this vector in object space or tangent space?

[calm rock]

Are you re-creating Unreal's nanite in Unity ? 😄

[hidden axle]

anyone got some for a vr game?

[arctic flame]

does anyone know why my object is moved when i use a shader graph ?

[lean lotus]

Is there a way to modify only the beginning X parts of a compute buffer in script to upload to the GPU instead of having to reupload the ENTIRE buffer to the GPU?(currently that large upload is a pretty large performance impact)

[arctic flame]

and now unity thinks the mesh is in the wrong place

[tiny shuttle]

When i edit the shader graph in editor (scene) and add animate the texture it lags , but in game it doesnt lag

[tight phoenix]

What are the words to describe to google the type of shader that is like, render X only within Y?

like you have a plane and you render something only when the plane is behind it

I cant find the words to google it but I know its a common concept

[regal stag]

Stencil

[tight phoenix]

Yess thats the one, thank you 👍

[dim yoke]

May it be because you move the vertices in the graph? 😅

[arctic flame]

i don't believe so

[dim yoke]

I think you did

Can you atleast show the graph?

[regal stag]

There's a setting at the top of the scene view on a dropdown to enable "Always Update". It doesn't update every frame to help with editor performance.

[arctic flame]

I didn't.

[dim yoke]

Are you 100% sure this is the shader your object is using?

[arctic flame]

yeah

[regal stag]

Maybe it's just a bug with the prefab view? Does it work like that in scene/game too?

[arctic flame]

it appears like this in the game as well

[dim yoke]

Do the graph happen to be saved?

[arctic flame]

it is saved yeah

in the main preview of the graph view it looks correct

but not in scene

[dim yoke]

Seems like 50% bug 😂

[regal stag]

Is the object rendered using a render feature, maybe with a different camera fov /offset or something?

[arctic flame]

i'm not sure what you mean by that

[regal stag]

Oh, you're in Built-in, then it's not that either

[dim yoke]

Maybe shader graph isn’t just working very fluently on birp yet…

[arctic flame]

:(

[dim yoke]

Have you tried restarting unity?

[arctic flame]

not yet

[dim yoke]

That’s usually the first step when you face a new bug

[arctic flame]

restarting doesn't seem to fix the issue either

[dim yoke]

So with standard material it works fine but using newly generated shader graph you get that weird bug?

[arctic flame]

that's correct

[dim yoke]

Then it’s definitely a bug

[arctic flame]

heck

[dim yoke]

Have you tried creating new shader graph again?

[arctic flame]

mm i have

i'm not sure how to update shader graph btw

[dim yoke]

What you mean update?

[arctic flame]

the shader graph package i have installed labels itself version 12.1.2

[regal stag]

The package is probably already using the highest version for that Unity version. If you want to update futher you'd probably need to update Unity itself.

[arctic flame]

on the documentation for shader graph it goes as high as 12.1.4 but the manager doesn't seem to go any higher than this

oh, i see

hm i will try updating unity then

[regal stag]

Though v13+ will likely be beta/alpha versions currently

[fervent tinsel]

@arctic flameSRP related packages have been part of Unity core for a while now.. you only get updates to them by updating Unity itself

2020.3 LTS is last one where you can actually use PM to fetch new versions for SG, URP, HDRP or VFX graph

[arctic flame]

I doubt this is an issue that was caused by versioning then

or will be solved by it

[fervent tinsel]

considering you are using built-in target, updating to newer version could solve it

built-in support for SG is new on 2021.2 I think and it's not all robust

I filed few bugs on it myself and Unity just closed them as "won't fix"

[arctic flame]

oh

target

[fervent tinsel]

there's a reason why Unity doesn't advertise built-in support on SG... it kinda exists now but it's not great

[arctic flame]

I didn't investigate that option at length

[fervent tinsel]

you are using built-in renderer, right?

[arctic flame]

that's right

[fervent tinsel]

ASE is most solid node based shader editor for that atm, probably will remain so... paid option though

[dim yoke]

What are the biggest problems with it and why can’t they just be fixed?

Well actually I’m not sure what is the unitys long term planning with all render pipelines. Maybe they are just going to get rid of birp and therefore doesnt bother updating it 🤷‍♂️

Atm there’s not really many reasons to choose birp over urp imo

[fervent tinsel]

@dim yoke it's not priority for them, afaik it exists so people can migrate from built-in to SRPs easier but I'm not really sure how this even helps there 😄

basically built-in target lacked all hardware instancing support when I reported those issues.. this pretty much made it impossible to use on VR as you can't do single pass instanced with SG's built-in target (end result just rendered one eye view)

I can't remember what happened with the regular instancing but that completely broke too... Unity's fix was to just remove the checkbox that let you enable it

Unity doesn't really support VR in built-in properly so the SPI issue didn't really surprise me

for example PP stack v2's TAA never worked in VR SPI and Unity also closed that issue as "won't fix"

then there's also this https://issuetracker.unity3d.com/issues/built-in-shader-graphs-emission-input-doesnt-contribute-to-gi

that one they haven't closed ... yet

[arctic flame]

generally i like to keep my graphics looking nice as they can so i'm interested in hdrp

however right now i'm not really certain of how mature it is as a thing i can conceivably use to run a whole project

what do you think?

[fervent tinsel]

depends on your project

you really need things that HDRP offers or would you be fine with URP? built-in could work for you too but I can't recommend using SG with it

ASE is great on built-in though

[arctic flame]

i'm fuzzy on the differences

[fervent tinsel]

HDRP is the highest end solution and is most featured out of the box, but it also comes with highest initial overhead which makes it so heavy it doesn't run on weaker hardware properly

also HDRP VR is going to limit your performance a ton

(if you need VR)

for VR, Unity is pretty much pushing you to pick URP

[arctic flame]

right

i definitely don't need vr

that's one starting point

[fervent tinsel]

URP is good all around pick if you want to use SG and want to future proof your project, it runs also on weaker hardware.. or if you don't want to deal with SRPs, just stick with built-in

[arctic flame]

srps....

[fervent tinsel]

by SRP I now mean URP or HDRP

[arctic flame]

oh, right.

[regal stag]

SRP = Scriptable Render Pipeline

[arctic flame]

ah

so URP is like

the less mature solution?

do they have a use case in mind?

[fervent tinsel]

answer you get to this depends to whom you ask that

[arctic flame]

hmm.

that makes me worry

[fervent tinsel]

URP is supposed to be the general purpose renderer

since you are new to all this, you don't have the baggage of "oh no things work differently than I'm used to doing for past 5 years" so URP could work just fine for you

[arctic flame]

for me the real concern is just

the likelihood of encountering a situation the pipeline isn't yet ready for

given that i understand it to be a very hefty change to make in the middle of a project

[fervent tinsel]

normally I'd just recommend trying out the options that feel sensible to you. but that would require you building prototypes on each which probably isn't in the cards now

Unity has some kind of upgrade path from built-in to URP or from built-in to HDRP but that's one way street and you can't swap between URP and HDRP easily once you've setup for one

[arctic flame]

unfortunately the shader graph generated code is suitably arcane that i can't identify the section i want to copy out for a written surface shader

is there a reference manual for the methods you have access to in shaders?

[tight phoenix]

Does anyone know how to use the 'Rendering Layer Mask'
I have an effect that I -think- needs masking, but I can't find any documentation on what this is, what it does, or how to use it.
https://docs.unity3d.com/ScriptReference/Renderer-renderingLayerMask.html Official docs say basically nothing

[regal stag]

It's basically a way to filter renderers when calling ScriptableRenderContext.DrawRenderers in custom renderer features/passes. https://docs.unity3d.com/ScriptReference/Rendering.ScriptableRenderContext.DrawRenderers.html
The function includes a FilteringSettings parameter, and that contains a renderingLayerMask bit mask. https://docs.unity3d.com/ScriptReference/Rendering.FilteringSettings.html
Afaik it's not really any different from regular layers (and you can also filter with those, using layerMask instead). But since those are tied to the physics system it's sometimes more useful to use renderer layers instead

[tight phoenix]

I see, thanks for the info

[regal stag]

Also as a side note, I think URP also claims a few of the renderer layers for the "light layers" in 2021.2+, which allow you to configure lights to only cast on certain renderers. But that's only based on reading the docs, I haven't tried using them yet. https://docs.unity3d.com/Packages/com.unity.render-pipelines.universal@12.0/manual/lighting/light-layers.html

[quartz rune]

Hello, I'd like to make my normals point towards the camera in shader graph but I am having a hard time finding out how

my objective is to, lerping between the original normals and the normals pointing to the camera, flattening the lighting to try an stylistic effect

[meager pelican]

You could try subtracting the world-space position from the camera's world-space position and normalizing it.

[shadow locust]

The camera node can give you the camera's position

[quartz rune]

im gonna try this thanks

like this?

[regal stag]

May also want to Transform to Object space as that's what space the vertex Normal input expects.
Or could also use the View Direction node (set to Object space), should be the same as that calculation.

[quartz rune]

how do I do that

the transform

[regal stag]

With the Transform node I mean (World -> Object, Direction mode)

[meager pelican]

Good point, it depends on where you do the custom-light calc. N dot L is usually world-space. OTOH, if you're using Unity's light calcs (I assumed it was custom in the frag), you're modifying it in the vert() like Cyan just said.

[quartz rune]

I think this works nicelyh

standard normals

lerp between flattened and standard

ill be trying it thanks a lot

[drowsy marsh]

can anyone identify what i am doing wrong with my shader here? why is it just giving me the default pink material?

[regal stag]

Since you're using the Universal target in the Graph Settings, make sure the project has URP set up correctly (pipeline asset assigned under project settings). See https://docs.unity3d.com/Packages/com.unity.render-pipelines.universal@12.1/manual/InstallURPIntoAProject.html

Make sure you also save the graph with the button in the top left

[drowsy marsh]

yeah, it wasn't set up right; thank you very much.

Hey yall, trying to make a simple snow shader with HDRP and shadergraph. How would I make it so that it also factors in the normal map when deciding where to put the snow? At the moment it just uses normals, but for something like a brick material I would also want snow to accumulate on the top of the bricks.

[drowsy fiber]

Hey guys, I have a fragment shader that indexes colors as a post processing effect. It works by choosing the closest color in a palette by distance for each pixel. This is the result:

Does anyone have an idea how I might blend the hard color transitions?

[wide thicket]

why are my colors completely different than the color I'm picking them as?

[shadow locust]

take a weighted average of the two closest colors by the distance to each color boundary

[wide thicket]

here's how it's supposed to look in blender

and here's how it looks in Unity

it's unlit so it comes down to the gradient being HDR, how do I fix that?

i'm able to recreate the bottom in blender by switching the color grading from standard to RAW, so is there a way to change that in Unity/ create a similar effect?

[wide thicket]

I tried fixing it with LUTs but I can't find whatever default neutral one unity is supposed to provide, so just grabbing them off google images and the results end up like this

i've tried 3 different ones they all go whacky like this

either way i feel im making this too complicated, and there's a better way to do this

just to reiterate what i need help with:

my gradients in Blender look like this, exactly how I want the colors to look

in Unity, it uses the exact same colors but the gradients look extremely different

even the color picker says it's a different color than what it is

[steep creek]

for some reason my shader only works on the scene view and not the game view. It works fine without a scene depth node (sample set to Eye) but it looks really bad without it. Any ideas on what's going on?

[waxen pewter]

guys, what am i doing wrong? why my material white in the editor?

[fervent tinsel]

@waxen pewterlook what texture is actually assigned to your material

your texture is a property there so material can override the default value

basically if you made the material before assigning that texture on the SG itself, it is likely to have just blank reference for the texture

[glad siren]

Hello, how can I make it so my Shader from Shader graph exposes these properties as well please ?

[amber saffron]

This is a capture from the lit material, right ?
If you want to have, let say, the surface inputs properties, you need to delcare them in your shadergraph and bind them to the outputs

[glad siren]

Do I need to take them all individually ? or is there a Property group to get this ?

[amber saffron]

Individually

[snow stag]

Hi!
I've been attempting to follow the answer on this unity forum post, but I cannot get it to work.
https://answers.unity.com/questions/1676725/how-to-have-a-point-light-with-no-falloff-in-unity.html
The post is not clear on where they are putting the custom written shader, but it appears to be usable as a shader for a material for objects in the scene.
I've tried putting this shader on a sphere next to a point light but I can't get the sphere to change colour at all, it just stays white all the time regardless of whether it is near a light or not.
If anyone could help me understand what I might be doing wrong that would be much appreciated.

In the image below I've got a standard shader sphere above and a sphere with the custom shader from the answer to that forum post. The standard shader sphere has a gradient of lighting and the custom shader sphere should have a hard line of light and dark, but instead it displays white all the way around.

[grizzled bolt]

Blender by default applies a type of tonemapping which makes everything look different
You would either disable the tonemapping or implement a similar tonemapping in Unity's post processing

[waxen pewter]

Yeah, you was right, silly me.. thank you!

[snow stag]

I figured it out. It was to do with the ambient light in the lighting settings making it difficult to tell if it was working or not because the 2 colours the sphere's shader was using for light and dark were both pure white.

[north raven]

Currently I'm using render textures to make image effects on what the camera renders (output texture -> canvas) the only problem is that the render texture is locked to a specific resolution is there a way this can be fixed ?

[compact umbra]

Hello all, I'm relatively new to game dev and I'm currently working on a 2d platformer and want to add some life to the background. I currently I have a still image for water and I would like to make it seem like it is flowing. Does anyone have a great tutorial they recommend for the material/ shader to go with

[tiny shuttle]

Shader graph question : How do i gradually change color from color A to Color B , in a looping animation

[regal stag]

You'd use a Lerp node to interpolate between the two colours. With the T input based on the Time node to animate it. For looping, could use the SineTime output, but remapped into a 0-1 range (use an Inverse Lerp with values of -1 and 1. Remap node works too), assuming you want it to gradually switch between each colour in both directions.

[tiny shuttle]

Wow i think that’s it thank you so much

[regal stag]

Also of note, Converting the colours into different colour spaces before lerping and then converting the result back to RGB might result in better looking transitions depending on the use case. But would be more expensive. Some examples here https://www.alanzucconi.com/2016/01/06/colour-interpolation/

[tiny anvil]

Ive assigned a "custom render texture" material to a spriterenderer, but nothing is being displayed?

The shader im using the exact same as the one in the unity docs

https://docs.unity3d.com/Manual/class-CustomRenderTexture.html

What am i doing wrong?

• my "material" has the correct shaderlab shader

• ive put my "material" inside of the field in my custom render texture

So why is nothing being displayed???

[wide thicket]

tried that, but again since the gradients come through as drastically different colors in the shader graph, it's hard to match the two accurately

any gradient with a darkish purple comes out as a washed out blue or black instead

[grizzled bolt]

Shader graph's preview is not terribly indicative of the material's appearance, if that's what you mean
It inherits some of the scene's lighting, and none of the post processing, I believe

Tbf trying to get perfect 1:1 conversion from blender viewport to unity scene is probably not worth the effort
In most situations it should be enough to eyeball it, if it looks 15% too bright or washed out, make the texture or post processing 15% darker and more saturated

But probably best to at least get rid of or minimize blender's tonemapping

[tiny shuttle]

Is blend node expensive? Is it way more expensive than multiply ?

[regal stag]

You can see the example generated code the blend node uses here : https://docs.unity3d.com/Packages/com.unity.shadergraph@13.1/manual/Blend-Node.html
It's definitely more than just a multiply but they aren't really that expensive. Depends on the mode, some are slightly more expensive than others.

[tiny shuttle]

Where do i see statistics on my shader

[dim yoke]

what statistics?

[tiny shuttle]

In unreal engine its called Instructions idk what it is called in unity but generally statistics to know performance and memory usage

[dim yoke]

I don't think there's such thing in unity. there may be some external tools for that tho

[tiny shuttle]

What do you generally do to test the performance of your shader if it’s expensive or not

[dim yoke]

I usually just compare it with other shaders. so make scene with a lot of objects using the same shader and then change the shaders for those objects and see how fps changes

I also like to make meshes like this (it's just ico sphere with individual faces scaled up a lot) to test shader performance so it covers a lot of pixels on screen (and change the shader to transparent so depth testing doesn't cut some work)

[tiny shuttle]

Alright thanks alot , Aleksih and Cyan

Do share when you find the solutions

[stark canopy]

By adding

to the SubShader (I believe it can also be added to individual Passes but I didn't need that here), it then made my shader adhere to the Mask component.

Hi all. Doing a runner game and we bought Curved World and have been using it for a while. Unfortunately, this has kept us from updating to more recent non-LTS versions of Unity which have some optimisations we need as well as a Apple Silicone version (which tremendously reduces crashes for us), but we're stuck either Updating and dropping Curved World, or not updating Unity. Curved World is not going to get updated until the editors go LTS, so we're kinda stuck. We tried making our own solutions, and trying those we found on the web, but none is giving us the same result. Would anyone know of a similar resulting effect than Curved World Z-Positive Runner shader ? (with X/Y curves)

[past wedge]

hi, I'm trying to compute uv screen position from any arbitrary world position in a fragment shader (orthographic camera), but I'm a bit stuck.. any idea?

Currently I have this, but I'm not sure:

float4 projected = mul(UNITY_MATRIX_VP, float4(worldPos, 1.0f));
float4 screenPos = ComputeScreenPos(projected);
float2 finalUV = (screenPos.xy/screenPos.w) * 0.5 + 0.5;

Hey, i'm doing a foliage wind shader with a fade, to make it sway more at the top. it works if i have sprites from different files, but if i use sprites from the same atlas they share the same fade position

the rings are assets from different atlases

[regal stag]

Master nodes were replaced with this "master stack" in SG v10+, you can't go back to master nodes without using an older unity version afaik. But that stack works the same. The alpha ports are only enabled if the graph is Transparent (or using alpha clipping, in which case both alpha & alpha clip threshold is enabled). Can change this in the Graph Settings tab of the Graph Inspector window (toggled with a button in the top right).

[hazy flare]

hello, I use mk toon shader in my builtin project (2019.4.33f1). When I take build for android, some devices renders shaders properly, but some don't. Anyone can help me what is this related to? I tried to change my graphic API settings but that doesnt seems to work

[regal stag]

My guess would be the other triangle is flipped, so using Cull Off in the shader might show it. Probably depends on how you're applying the render texture to the screen.

[regal stag]

Maybe with AsyncGPUReadback : https://docs.unity3d.com/ScriptReference/Rendering.AsyncGPUReadback.html
(example : https://github.com/keijiro/AsyncCaptureTest)

[regal stag]

I'm not familiar with the Curved World asset but in the past I've done some world bending stuff using this, if it helps. Assuming you're in a pipeline that can use Shader Graph. Same techinque could be applied to shader code though.

[regal stag]

Don't think you need the *0.5 + 0.5, but other than that it looks correct

[clever saddle]

Is mesh.uv only used for storing uv data for texture uv?What if mesh.uv changes,will some changes of texture in model take place?

[past wedge]

@regal stag I think I'm closer with this (but sill not correct):

float4 screenPos = mul(unity_WorldToCamera, float4(worldPos, 1));
float2 finalUV = (screenPos.xy / screenPos.w) * 0.5 + 0.5;

I'm in a postprocess shader so I don't think I should use ComputeScreenPos :/

[regal stag]

The mesh uv channels (there's up to 8) can store any float4 data. It doesn't have to be used for textures, that's up to the shader. But typically yes, mesh.uv (first uv channel) is used for mapping textures to the mesh.
Unity also uses mesh.uv2 for baked lightmap uvs iirc, assuming the model import is set to generate them.

[regal stag]

If UNITY_MATRIX_VP doesn't work, can maybe try

float4 viewPos = mul(unity_WorldToCamera, float4(worldPos, 1);
float4 clipPos = mul(unity_CameraProjection, float4(viewPos, 1));
float2 screenPos = (screenPos.xy / screenPos.w) * 0.5 + 0.5;

Otherwise may need to pass the camera matrices into the shader yourself. e.g. using camera.worldToCameraMatrix and GL.GetGPUProjectionMatrix(camera.projectionMatrix); (I think), with material.SetMatrix / Shader.SetGlobalMatrix

It depends how the image is being applied. Some methods basically use an orthographic projection so overrides the projection matrix (that might only override UNITY_MATRIX_P and not unity_CameraProjection though)

[past wedge]

@regal stag wow thanks, it's working!

with all these tests with matrices, I forgot the projection matrix in the end... 😢 thanks a lot!

[regal stag]

You'll likely need to rely on UV space for the fade, rather than Position (Object space). You can't really rely on Object space for sprites, since multiple sprites using the same texture may get batched/combined and drawn together, it then acts like World space iirc. (Hence why the sprites using the same atlas here are sharing the same fade)

That said, even with UV space you'd still need to know the UV.y values that the texture starts and ends at in order to remap it into a 0-1 range, and pass those values into the material - which means different materials for each sprite (type), which would prevent batching and be more draw calls, so kinda defeats the purpose of even using an atlas.
(Unless you can pass those values into the sprite mesh? Like via an unused uv channel? Not sure if the SpriteRenderer really gives access to doing that though. Could use the color field (vertex colours in shader) since that's currently looks unused)

I'm not all that familiar with 2D/sprites so I'm kinda rambling. But maybe there's another way I'm not aware of, others might be able to help further.

[regal stag]

I'm not all that familiar with preloading. But you might be some info here which can help. Like the ShaderWarmup or ShaderVariantCollection apis. https://docs.unity3d.com/Manual/shader-loading.html
And to obtain a reference to a shader can use a public / serialized private field, or if the shader is in a Resources folder should be able to use Resources.Load https://docs.unity3d.com/ScriptReference/Resources.Load.html

[amber frost]

hi

can anyone tell how to import these materials to blender

i exported models to fbx but when i imported those things into blender, i cant see any textures

full pink, white things

i want wrk this things in blender

[glad siren]

Hey thanks ! I actually got one kinda working like I wanted, but yours seems to do the same and is simpler so I've adapted yours to have X/Y curve as well. I just need to create some sort of CurveController as to not have to modify each material curve one by one.

[graceful pecan]

Thanks yeah i figured!
yeah one way i'm thinking about is to use the masktexture feature that can be applied to a sprite and then use that as a fade for objects

might try that

[grizzled bolt]

You can't

[amber frost]

soo i cant do texturing for those objects??

[regal stag]

You can set the graph properties to non-exposed and set via Shader.SetGlobalFloat to easily have all materials share the same value

[grizzled bolt]

Sure, but the formats aren't compatible
You need to recreate a similar material/shader in blender

[amber frost]

🥲 k ty 4 the reply

[white marsh]

ok so earlier i made a super simple water shader which is basically vertex displacement using a noise map. at this point i want things to float on the water so i where thinking getting the vertex posititions and normals in order to have kinematic objects look like they float in the water. but the mesh vertecies do not update from the shader displacement ofc so how can i get the vert positions?

[glad siren]

Hmm never done it myself but I'll look into it. I also need to figure out how to give an offset as to not curve immediately, aswell as having the curve be only on Z Positive, and not apply if I look behind 😅

[regal stag]

Will probably need to remove the Absolute node if you don't want it on both sides. And do some remapping & clamping

[regal stag]

You can't easily obtain the vertex positions on the CPU after displacement in the shader/GPU. I think the usual way to do water buoyancy is to recreate the same displacement calculation in C#.

[white marsh]

hmm, i see. that would make a lot of sense

[regal stag]

An alternative might be to use an orthographic camera to render the water's depth to a render texture then use a AsyncGPUReadback request to read it back on the cpu. But not sure how well that would perform.

[white marsh]

i think ill just recreate the calculations in c#, its a fairly simple displacement so it shouldnt be too bad

[glad siren]

Alright, thanks ! 😄 I don't know but I'll try

[dusty coyote]

Hi, have a question, I have two shaped that use object scale as input so they scale like I want, but if they are on the same order in layer or don't use two different materials they get warped like on the second picture, I understand that the object scale input they get if in same order in layer is like same for both?

Is there anyway to fix this without changing their order in layer or creating a new material for each new object (i need a lot of objects with different scales)

[regal stag]

If these are sprites then this occurs because they get batched when using the same material. You can't rely on things that use object space / model matrix, and the scale here is probably calculated using that.
You might be able to solve this by using a sliced sprite though. https://docs.unity3d.com/Manual/9SliceSprites.html

[dusty coyote]

Okay yeah thought I was being clever, I'll use the suggested approach, thank you.

[clever saddle]

I got it.Thx

What depends the nums of mesh.uvs?And index of mesh.uvs?

[glad siren]

I got everything working, Curve controller, Positive only, and the offset ! 😄 Thanks a lot.
As a last question, do you know how I can get my Shader to expose basic properties like basemap and all like normal shaders do but for shadergraph, so I don't need to create all the properties everytime ?

[regal stag]

There's no automatic way of setting up those properties. You could create a graph with those set up as a sort of template though, and duplicate that shadergraph file rather than creating a new blank/lit one.

[dusty coyote]

I found a pretty stupid solution, I just disabled batching in the shader, are there any cons to this?

I don't use lights

Or is it just a performance thing, don't quite understand

[low lichen]

Sprites are pretty heavily batched. That's the reason you make sprite atlases, just to improve batching.

[dusty coyote]

And the point is to improve performance?

[low lichen]

Yes, to reduce draw calls

[dusty coyote]

Let's say I like 20 objects each using the same shader with disabled batching, how bad is the performance hit?

Like is it a couple of precent or like multiple times worse

Tested like with a 100 of them no noticable difference in my case so i guess it's fine

[low lichen]

Worst case, you'll have 20 draw calls there where you could have possibly had 1 draw call, assuming the sprites are in an atlas and a favorable sorting scenario

[odd mauve]

Yeah you probably won't notice a difference unless you get up to many thousands of sprites.

[low lichen]

Mobile devices generally don't like more than a few hundred draw calls.

[odd mauve]

Oh that's true, I was assuming you're on a gaming PC.

[glad siren]

awhh thats sad to hear, seems like something we'd use a lot ^^

Anyone know the difference between Lit and Simple Lit shaders ? I can't seem to find any recent info on the subject (using URP)

[low lichen]

This is up-to-date
https://docs.unity3d.com/Packages/com.unity.render-pipelines.universal@11.0/manual/simple-lit-shader.html

The difference is explained in more detail in the "Simple shading" section.

[glad siren]

Oh damn, thanks, must have skimmed through it too quickly 😵‍💫 let me take a look !

[glad siren]

Hmm, I don't have a "simple shading" section ?

[low lichen]

https://docs.unity3d.com/Packages/com.unity.render-pipelines.universal@11.0/manual/shading-model.html#simple-shading

This shading model is suitable for stylized visuals or for games that run on less powerful platforms. With this shading model, Materials are not truly photorealistic. The Shaders do not conserve energy. This shading model is based on the Blinn-Phong model.

In this Simple shading model, Materials reflect diffuse and specular light, and there’s no correlation between the two. The amount of diffuse and specular light reflected from Materials depends on the properties you select for the Material and the total reflected light can therefore exceed the total incoming light. Specular reflection varies only with camera direction.

Light attenuation is only affected by the light intensity.

[glad siren]

Oh in the Shading Models, alright alright. Thank you ! Let me read up 🙂

[white marsh]

i think ive gotten it to work how i want, but it seems like the waves are offset, i assume this is because the shader's _Time.y is different from Time.time, so i heard that Time.timeSinceLevelLoad should be ok, but it still seems to be off

[regal stag]

If _Time.y & Time.timeSinceLevelLoad doesn't match you could use a custom float property and update it each frame using material.SetFloat (or global float property & Shader.SetGlobalFloat)

[white marsh]

right ofc, actually i remember i did that on a different shader. idk why i didnt think of that now

actually, that apparently wasnt the problem, the problem was that i was applying the water displacement position to the object inverted so it went up when it was supposed to go down

[full salmon]

In our project we've got a shader that has up until now rendered on top of everything else. If I wanted to change it so that when it's behind a certain type of object it looks different, what sort of thing would I need to look at changing?

[distant river]

Do you think there will ever be an analogue of nanite for unity? Maybe the developers are thinking about it, I'm probably sure we'll get something similar in the future, do you think?

[odd mauve]

I'm sure they're working on something given their acquisition of Weta and ambitions in the film sector.
All those film-quality assets are gonna be useless if Unity can't auto-convert them into runtime assets. But I think Epic have quite the head start...

[distant river]

Yes I've heard about weta digital, but I haven't heard that they want to do something like nanite, although maybe it's in the early stages, I still think we will get something in the future, probably

[odd mauve]

Oh, nothing has been announced. But Unity are clearly looking to get in on the virtual production sector like Unreal, and to succeed there they need some way to make VFX industry assets usable in a runtime engine, like Epic have. So they will definitely be working on SOMETHING similar.
