#

and again, don't blame me, this is something internal with unity

devout sun
#

I recommend you to start a Surface shader from zero and add a lerp between 2 textures

true elbow
#

pain

#

it would be helpful if I could just add in my properties and have it work

#

I did something similar with the particle shader

#

although that was more... deletign something than adding it in

devout sun
#

are you sure that you only need a lerp between 2 textures?

true elbow
#

Well I need to also re-implement a normal map and the like

#

Honestly, I grow tempted to just implement all of image modes in GIMP

#

with the whole factor thing, which I suppose would just be like... a lerp between the base version, and the modified one

cosmic prairie
#

why use builtin again? in shader graph it's just 1 node

#

much more begginer friendly

true elbow
#

I have a customized particle shader that partially disables color over lifetime

#

and unless there's a shader graph version of the standard shaders in URP

#

which would be cool

#

I don't wanna dig through URP's shaders to re-do part of my work

cosmic prairie
#

what do you mean? there are lit and unlit variants

#

can be transparent and two sided

#

like a particle

true elbow
#

does that come in shader graph form

#

because, to be blunt

#

I feel I can manage writing actual shaders from scratch. I just despise working with a copy-pasted version of the standard shader

#

Unity has so many include statements that it is near-impossible to actually figure out what is doing what

#

at least for me

cosmic prairie
#

there are URP shaders that mimic shader graph defaults

#

and URP defaults

#

if that is what you mean

true elbow
#

then I might switch over to that workflow later

cosmic prairie
#

but this is all the properties you can modify in shader graph:

true elbow
#

I've messed around with shader graph before

#

I know it in general, and I have plenty of experience in blender

#

It's just that I don't wanna have to change my entire workflow. Plus, this is for a VRChat avatar, and although they recently added support for URP... I've heard the most recent patch was questionable overall so I'm cautious to switch

cosmic prairie
#

anyways this should be an example

#

if you do decide to switch

true elbow
#

sorry if I'm coming off as arrogant

cosmic prairie
#

no, it's fine

true elbow
#

tbh

#

I probably should switch

#

I know generally how to program, but it is so much easier to just link up some nodes

cosmic prairie
#

if you need it for VRchat then builtin is okay I guess, but I can't imagine how they are using both pipelines

#

or why

true elbow
#

Yeah I have no clue either

#

magic, I guess

cosmic prairie
#

my guess would be they switched to urp and they are converting builtin ones automagically? Ill look this up

#

hmm

true elbow
#

that's odd. Could have sworn they announced they supported it now

#

a few months back they were upgrading to unity 2019 and I heard mentions in the community of getting URP working

cosmic prairie
#

well it would be nice if they made the switch but then they need to create a shader converter haha

true elbow
#

welp time for custom BS shaders it is

#

man do I feel dumb

#

went through all this effort when I could've just made one from scratch

#

apologies for wasting your time in some sense, considering URP is unworkable for what I'm doing

#

tho I have another question. Wit something that's only transparent in some spots, how do I still have it be transparent, but not have such a silly render queue position

#

as it's a semi-transparent piece of clothing, and the model it's attached to starts rendering it on top

cosmic prairie
#

the model is also transparent?

#

you could enable zwrite on one of them

#

if that would solve it

#

really depends on how it looks like

#

you can send it to me in a dm if you do not want to post it in public

#

looking at it would really help tho

kind juniper
#

There's one thing I don't completely understand about shaders and google doesn't seem to produce any good explanation: I sometimes see shaders that omit the vertex shader(function?) completely and only have surface(is it the same as fragment btw?) shader. Does it mean that unity automatically adds the the default vertex part or that the transformation to view space does not happen?

#

Is surface shader a different approach to vertex+fragment shader?

#

Alright, I think I answered my own question. 😄

teal breach
#

I seem to have some issues with shadergraph constantly throwing null reference exceptions on a particular shader graph I made

#

If I add any keywords to the blackboard, it spams console with Assertion failed, ArgumentNullExceptions and NullReferenceExceptions - I then can't save or really do anything further, have to close SG and reopen

#

anyone have any ideas what to avoid/how to fix?

meager pelican
# true elbow welp time for custom BS shaders it is

Jumping in, catching up, and guessing.....
So this post may make history as the most useless post on Shader Discord...

However, the shader optimizer MAY strip out properties that are not used by the shader code somehow. And the standard shader source isn't generated from ShaderLab that I know of, it's hand-written special, or customized by unity somehow.

So that property you're trying to add SHOULD show up if you get the right sections and the billion variants edited to include using it. I think....

The other thing to check is that the standard shader has a custom material inspector...so the property may actually be there, and accessible by script, but might not be showing up in the inspector's view. Try setting the value of your custom property in script and seen if it changes the results, even if you cannot see it in the inspector.

I'm GUESSING.

But a property definition should be accessible You SHOULD be able to clone the shader, edit that monstrosity if you really wanted to, and add the property. In theory. So I feel you pain.

This is just a comment up and above all the "why don't you just use..." stuff. I haven't tried editing the standard shader in a few years! So I don't really remember all the details, and it may have changed anyway.

true elbow
#

I have already made a solution just by making a shader from scratch with the help of Peter226

#

I say "with the help of" but he did a lot

#

ran into another issue but it seems to be way more fundamental

meager pelican
#

Yeah, I saw that later. 🙂

swift loom
#

If I do tex2D or tex3D on a repeating texture, is 1 the start of the next loop instead the end of the texture?? So it's 0-0.99999999 then 1-1.9999999 etc

true elbow
#

but now I collapse because it is 6 AM and I just spent several hours trying to edit a shader when I could just make my own

#

time for sleep

swift loom
#

and if so what's the best way to avoid the loop without clamping it? just do if > 1 variable = 0.9999999 ? 😄

meager pelican
# kind juniper There's one thing I don't completely understand about shaders and google doesn't...

You're talking about Surface shaders. Unity Surface Shaders are "just" syntactic sugar for vert/frag shaders GENERATED by the Surface Shader processor. So when it generates the shader, if it doesn't have a specified Vert() function, it generates a default one.
So in your question, option #1 is the answer.

Shaders MUST generate the transformation to CLIP space out of the vertex stage, to prep for rasterization that happens between the vert and the frag.

ok

warm geyser
#

and i did

#

but after all it only fixed water

#

and the rest still pink

low lichen
#

Nature/SpeedTree is for built-in

warm geyser
#

oh

#

i changed, but still pink, i changed the tarrain prefab to Universal Render Pipeline/Terrain/Lit

#

and it look better

low lichen
#

Which shader did you choose? There are multiple SpeedTree shaders

warm geyser
#

speedtree7

low lichen
#

Try SpeedTree8. I'm not sure why the material inspector is so empty.

#

Oh nevermind, you have the terrain selected

#

Are you sure those materials you edited are the ones actually being used in the scene?

warm geyser
#

alright its fixed

#

but for some reason

#

it look rlly weird

low lichen
#

The properties are probably slightly different and don't automatically convert correctly, so you might have to change the properties to get it to look right.

Anyone know how I can get the Z coordinate of a tile inside a tilemap shader?

#

All tiles seem to share the same Z coordinate, even if they are set at different coordinates using Tilemap.SetTile(x, y, z, Tile)

Hi guys, i'm trying to compute (in a compute shader) a vertical height texture of my level, but i have no idea of how i could access height information? This is because i am creating an ocean system based on gerstner waves, and i'd like to use the depth of ocean floor to modulate some wave parameters, so i thought my game would just compute a height map of the level at load and then my shader would sample that texture to get the height info. The thing is, my ground is not made from a terrain with heightmap, but just meshes placed by hand. Any idea about how to go about this?

#

I'd like to avoid to have to set a camera on top and use zbuffer

low lichen
vernal pewter
#

It's the same for all vertices, even if there are tiles with Z != 0

kind juniper
#

So, it could be that each tile is actually and individual quad.🤔

vernal pewter
#

It is

#

Each tile is a quad

#

I originally thought they used greedy meshing, but they don't

kind juniper
vernal pewter
#

I wonder how they do that then, since the default sprite shader works for tilemaps. I assumed it would just be in the x/y/z position of the vertex in the vertex shader

Hey, I am using the ShaderlabsVS extension for Visual Studio to make shaders.
For some reason whenever I am using ShaderlabsVS and press enter to go onto a new line underneath my code it starts my line at the beginning of the line instead of underneath my code.

Is there anyway to fix this? I've been trying to figure out why that is for a while now

I'm using Visual Studio 2019, I also tried switching to Visual Studio 2017 to see if it would fix any issues

rustic dagger

yeah, it doesn't say 19 is supported, although it says it might be

#

2017 still gave you the same issue?

grand jolt
#

Yep, same issue sadly

rustic dagger
#

any other extensions might be in the way?

grand jolt
#

I don't think so, I made sure to disable every custom extension I had installed to see if it could be that but it doesn't seem to be

I've also tried resetting keybinds to see if it could be anything like that to no avail

Hello everyone! Can somebody help me, please? I tried to create my first shader and can't understand why it doesn't show me the colour and texture.

I need the result model to look like this.

meager pelican
# outer shuttle I'd like to avoid to have to set a camera on top and use zbuffer

The easiest way is just to use scene depth texture and convert the ocean bottom to World-space, the Y value is the depth relative to some value for the water. (this is just as you draw each frame, for what is on the screen, no master-height-map required)

Buuuut...simple-height may not be what you really want (nor the depth texture) since it's also about eye-depth to that point, and refraction if you want it.

But if you MUST have a height map, you can compute one for the scene in the terrain-mesh shaders as you draw each pixel, since you have that info anyway. Then you don't need a compute pass...that's another idea if you don't like the WS conversion idea above. That would require MRT support though, I think (maybe not, maybe you can update another texture but I'm unsure).

#

Short of all those ideas, the top-down camera is probably the easiest way, and doesn't need a compute shader (IDK why you'd use a compute shader for this).

brittle owl
main flax

#

so, what kind of model is this being applied to? and correct me if i’m wrong but the effect is just a fade to full transparency from bottom to top right?

main flax
brittle owl
#

i see, i think there’s a better way to achieve the effect

#

use the y position of the object (in object space) to lerp between 0-1 and then plug that into the alpha, and then set the color to whatever you want the color to be

main flax
#

And the colour should also glow, like hologram.

main flax
#

Or just tell me which nodes I need

brittle owl
#

oh i’m not at my computer but i can try to take you through it

use the position node and set it to object space, put the output into the split node and i think you take the g value and plug it into a lerp node’s time input. then make sure the lerp is going from 1-0 (or 0-1 if it’s reversed), plug the output into your alpha, and then to make it glow, take out all inputs to the emission, change the color to that blue you wanted, and in the same color menu at the bottom there should be a slider for intensity, just raise it until it looks right

main flax
#

It's much better, but I can't reverse the lerp.

Scene2.PNG
#

Whatever combination of ones and zeros I use in lerp and inverse lerp I can't get the visible lower half and invisible upper half

main flax
brittle owl
# main flax The graph shader now looks like this

a few things wrong, the position node is not set to object space, you might need to flip the 0 and 1 in the lerp node if it’s going in the wrong direction, and what’s the point of the fresnel and texture you’re putting in? also the emission should just be done like how i was saying if you’re trying to achieve a glow

main flax
brittle owl
#

position in terms of the object. for the g (which is the y value) it will be from 0-1 going from bottom to top

#

How to add the multiply and add parameters?

#

#

meager pelican
#

What do you mean by "glow"?
Light emission? (Lights other objects in the scene)
or
Bloom post process? (a blur for certain brightness levels of pixels)

Thank you)
And I think it's closer to bloom.

hardy aurora
#

i don´t know if my question classifies as a shaders one but

#

i have to make an object that changes colour depending on the light that hits it

#

and i have absolutely no idea how to do that

#

are there any tutorials that anybody could recommend

#

or something that i could reasearch?, i am not being really lucky finding exactly what i´m looking for

meager pelican
#

That sounds like a shader question.

But what exactly do you mean by "changes color depending on the light that hits it"?

What's the RGB color-math?

FYI - Light color already gets multiplied by albedo color automatically. So a red-only light will only show the red parts of any object's color.

#

@hardy aurora

hardy aurora
#

basically what i got asked to do is, like an object that when in contact with direct light will display a different colour, at least on the area it is being hit

#

instead of simply looking brighter on the area the light is hitting it, it´s lighter colour will just be a different one

#

something like that

#

however i am rather new to shaders and can´t seem to find a tutorial or course that goes into this specifically

meager pelican
#

Did you try just changing the light's color? (I'm still unsure of what it would look like from your description)

Is the light a different color? Or is it by light-number? Is it a flashlight type of thing? Or some lantern?

hardy aurora
#

no it isn´t a flashlight thing, it´s basically an object that instead of reacting to light by darkening the areas where it has a shadow

#

the shadow is just a different colour to the one the object normally is

hardy aurora
#

and complicated i guess

#

the world is supposed to have a normal light and interactiopns with it, while this object has a different one

#

if it is too complicated i´ll just make this object gradually change colours as time goes on

meager pelican
#
  1. It's definitely a shader question. Unique lighting.
  2. Anything is possible, but not everything is easy to explain nor necessarily do.
#

You could use an unlit shader, and "just" calculate lighting manually for your no-light-intensity shaded object.

#

The lit shaders will mess with the lighting.

hardy aurora
#

mmmmm, a lerp node could help with this

meager pelican
#

node?
So URP or HDRP?

#

What about shadows?

hardy aurora
#

was thinking of using universal render pipeline system and an unlit shader graph

#

though if your option is simpler i´ll definately take it

meager pelican
#

That's basically "my option" too.
But you'll have to loop through the lights manually, and do different calcs than normally done. Since you don't want intensity. There's resources on that.

#

Cyan wrote some, one second.

hardy aurora
#

thank you!

#

this helps a lot

#

again sorry for not getting it inmediately, i´m new to shaders and just trying to learn

meager pelican
#

No apology necessary. And it sounds like you're on the right track, thought-wise. 🙂 Now you'll have to dig in, experiment, and get back to us with specifics.

Hi

#

I am trying to set environment reflection for a material through script at runtime

#

I am able to change the metallic and smoothness by setting the float between a range of 0 to 1

#

But when setting a float value of 1 to environment reflection, the effect is not reflecting during runtime

#

The material I am trying to change has a environment reflection set to false, I want to set it to true. Through script.

Can someone please help me with this?

Does anybody know if "official unity decals for URP" are a thing already? i saw that there seems to be a unity Decal Renderer Feature for URP 12.0.0 but I only have URP 11.0.0 for Unity 2021.1.20f1, is URP 12 not out yet?

I downloaded another URP Decal System but i don't like it since it completely ignores shadows and makes everything look weird so i was hoping unity would offer something more advanced

low lichen
# rare ore Can someone please help me with this?

You have to enable the corresponding keyword. What the keyword is depends on the material. For the Standard shader, it's _GLOSSYREFLECTIONS_OFF, so you'd want to do Material.DisableKeyword("_GLOSSYREFLECTIONS_OFF") to enable reflections.

hi @low lichen , remember the grayscale blur? I seem to have really bad performance in vr. Could it be the shader or did I enable wrong settings somehow? (using empty scene with only the post process and an xr rig)

#

disabling all post process effects give a lot of performance back, but still not even 90fps

ornate skiff
#

is it possible to get the final position (in c#) of a vertex after it has been displaced by a shader? i.e. so i can displace a mesh and then place another object on it's new position

when i check the vertex positions in unity it still returns the non-displaced positions (even though the object is moved) so i'm guessing it's not possible?

Quick question on vector * scalar operation in hlsl --
Are the two below statements equivalent?
Assume arbitrary values in a defined float3 variable, "val"

(1) val *= 0.5;
(2) val *= float3(0.5, 0.5, 0.5);

Yes. (1) is a component-wise multiply because val is a float3.

from what i found online, a gstack texture is just a texture that holds:

AO in Red
Roughness in Green
and Specular in Blue
idk if there’s anything in the A channel?

if you’re using shader graph, split the texture into its individual color components and feed them in to the correct master node inputs

#

Anyone down to help me with a theoretical question that's likely shader related?

#

Does anyone have any idea how the Animal Crossing achieved sprite sheet eyes that also normal map the face around them?

#

Typically the technique for doing 2D facial expressions on a 3D model is to duplicate a portion of the meshes face geo, overlap it, and then use that for the eyes/brows with texturing

#

But I don't really know how they managed to get the normals of the face to dynamically adapt to the 2d face expressions

#

Here's a good example as well

#

I'm fairly certain the eyes are just one spritesheet, but you can see (at my timestamp) the eyelids are raised, while the eyes themselves are inset on the face mesh

#

There's definitely no way they are swapping out the entire texture of the face just for the eye expressions either, that would be insanely inefficient

#

Perhaps I am just overthinking this

fleet rampart
mental bone
grand jolt
#

It looks like the actual base texture of the head reacts to the normals of the eyes and mouth

#

If you just do normal mapping on the eyes/mouth without the head also having it, it looks really off

#

Okay I made something real quick

mental bone
#

So add the normals to the head as well. We are not talking about 8k textures per char. The other solution might be blend shapes

grand jolt
#

Since in the game, the sprites of the eyes/mouth are constantly changing

mental bone
#

Like a sprite sheet? You get a frame id for the type of eyes and you know where to sample each map for that id

vocal narwhal
#

Some decal shaders have separate opacity for normals

#

like, HDRP has an option to use the blue channel from the mask map for the normal map opacity

mental bone
#

The number of frames has to be the same Im not sure why you would need to line them up

grand jolt
#

That's not what I mean

#

hold up

#

I mean the UVs of the eyes and the head are going to be completely different, and I don't think it makes sense to constantly swap the normal map of the head with the eyes and mouth because that's an absurd amount of combinations

#

This thing I made real quick

#

The eyes are their own map like this

#

and the head would be whatever

#

And this is just the texture I used for the eye

#

So that would somehow have to be translated to the head normal map for every single expression and mouth movement

#

Which doesn't make sense to me

#

Unless there's some clever way Nintendo unwrapped their meshes and I am kind of lost on how they did this

#

Do you get what I mean though?

#

The pics I posted above are a standard technique they've used in the past

#

they used the same technique for Twilight Princess

#

but the eyes in that game weren't normal mapped like in ACNH so it's a lot easier to pull off

What I dont get is if the eyes are on a seperat mesh why do you need to change the normals on the head?

grand jolt
#

To get the inset that you see in the game

mental bone
#

Expressions are gonna be happening on the eye mesh

grand jolt
#

If you dont do it on the head as well it looks really weird

#

Again, I could be completely wrong

#

I've got 2am brain

mental bone
#

The mesh you showed will cover that whole area its normal will make the eyes look like that

grand jolt
#

Yes it would but the eye sprite has transparency so that the texture of the head can be seen

#

I have an idea on how I might do it

#

but I don't think it's correct

#

Maybe I will experiment tomorrow

#

¯_(ツ)_/¯

grand jolt
#

I don't know if that's a dumb question or not

#

Because in my mind, if they were, it would totally work

vocal narwhal
#

It's likely what you're doing, but the point is finding a shader with a separate alpha for the normal map

grand jolt
#

Can't decals in HDRP affect the normals of whatever its projecting on?

vocal narwhal
#

Yes

grand jolt
#

Shit, my project is in URP

#

and there's no decals in this iirc

vocal narwhal
#

There is, but their shader is not built with separate normal map alpha afaik

grand jolt
#

Wait there is?

#

o.o

#

Since when?

vocal narwhal
grand jolt
#

Wait what

#

is this brand new

#

I remember people saying for the longest time only HDRP had decals built in

vocal narwhal
#

2021-01-11

grand jolt
#

Is that stable?

vocal narwhal
#

It doesn't say preview, so yes

grand jolt
#

Oof

#

im on 2019.4.19f

vocal narwhal
#

It may require a beta/alpha Unity though, no idea. I don't keep up with the details

#

Yeah it's certainly not gonna be that old 😛

grand jolt
#

Well shit, I might try that out

#

Im sure there's a lot of changes from 2019 to 2021

#

Now in your opinion, does it make sense to handle eyes/mouth 2d sprites for character with decals?

#

I'm not sure if there's any downsides or anything

vocal narwhal
#

I don't really think there's a reason to. As far as I know decals benefit from projecting across different surfaces and ease of authoring

#

You've got a fixed location, you just need to find/create a shader that has separate opacity for the normals

grand jolt
#

I'll probably continue this tomorrow night, getting sleepy

white cypress
#

the eyes are definitely not decals, there are model rips out there that don't require them

grand jolt
#

And they look the same ripped?

#

I mean I could try reverse engineering that

white cypress
grand jolt
#

i got this one

#

it has Raymond too

white cypress
#

regardless, its likely just texture swapping. its not a hard thing to do even with normal maps

grand jolt
#

Oh my god

#

It literally is just that

#

Yea I guess I didn't expect it to be that literal

#

I didn't realize they were swapping out the normal map, albedo, specular, etc. for every single expression

#

I thought they eyes and mouth would be separated

#

well thank you

mental bone
grand jolt
#

Can I make this affect the mesh collider as well?

hey, im looking for a simple plane mesh outline shader. basically i just take the mesh. copy it 4 times and offset to make it look like outlines. i already did that with the raw mesh, but i have no idea how to translate this to a shader in hlsl.

teal breach
# meager pelican If it's a custom shader you "own"...and you always want the keyword enabled, jus...

The problem is this approach does not work when using e.g. SG lit shaders, such that the keywords are used in Unity's internal functions. For example, I need to ensure that _SPECULARHIGHLIGHTS_OFF is always enabled - it's used in Unity's internal lighting calcs. I tried hacking in a define using custom script nodes, but couldn't get it to work. The only way to have it work in this case is to define the keyword on the blackboard and then have it always enabled in all my materials (which feels clunky).

Hey !
I'm using shaders on a cube to color it. In the scene, there can be gameObjects that use the Sprite-Lit shader to render an assigned texture.

When I do that, there's 2 choice ; The cube render in front of the Sprite-Lit, or the Sprite-Lit render in front of the cube.
I'd like to take the 3D position in count for this case, which means using a Lit shader instead of a Sprite-Lit one.

How can I put a texture on an material using a Lit shader (as for the Sprite-Lit one) without having it to affect every other object that have this material ?
Basically I'd like a prefab that got the material to get a selected texture to be attached to it and have another prefab that would have the same material but a different texture, but I can't find a way to do it

Does the ShadowCaster pass in URP simple lit shader run if shadows are disabled in the Render pipeline asset?

#

Could I say, remove that pass and get more performance?

low lichen
#

That pass won't be used. The most you'd get by removing it is smaller build size and shorter build time, if it's not already getting stripped.

#

And the difference would be very small for one ShadowCaster pass

i was following a tutorial that gives me a glowing shader, and it works with one issue: my (usually transparent on the sprite) background, is opaque, yellow, and has a weird shape, help?

#

the sprite has no background and it was there upon importing, before i added emission

#

im assuming there's like a cull transparent mesh tickbox somewhere im missing

#

it looks like this on the first bit of the shader so thats where the problem is

cerulean dune
#

Well with URP Sprite Lit shader, it's used to render the sprite attached to the game object

But since this sprite is from a 2D/UI texture, it's rendered different (3d space isn't considered)

So I'd like the same behaviour but for a 3d space. Otherwise the project would get messy :s

Im looking to change the colour property on my VFX graph. forums say i need to use SetVector4, But its asking for an ID?

How do i get an ID of a colour property?

low lichen
#

@wary horizon Shader.PropertyToID

wary horizon
#

i think i've used the wrong channel

#

this is a visual effect

low lichen
#

I usually define it in a one liner like this:

private static readonly int PropertyNameID = Shader.PropertyToID("_SomeProperty");
#

VFX Graph uses shaders too, compute shaders

wary horizon
#

there is no reference name, so im a little stumped

unknown.png
low lichen
#

It's probably just BloodColor then

wary horizon
#

I'll give it a go. i swear there was a box above ToolTip that was ReferenceName or something

#

last time i used vfx graph

#

oh it takes a string aswell

low lichen
#

The id is more efficient. The string version just calls Shader.PropertyToID every time when you can do it just once.

wary horizon
#

oh ok cool, I'll use the ID then

#

i guess its similar to hashmap for animation

#

hash something. canny remember

wary horizon
#

@low lichen Do you know how to achieve intensity of this?

#

effectProperties.SetVector4(bloodColorID, new Vector4(191, 16, 0, 255));

#

would i just times the V4 by some value?

low lichen
#

So it already should be super intense with numbers that high above 1

wary horizon
#

the inspector shows me 255

low lichen
wary horizon
low lichen
#

That's just because you have 0-255 mode selected in the color picker

wary horizon

Ah

i guess theres a ref name somewhere

But unity would not like to give me it

Well, you could take a wild shot and put an underscore ("_") before the name...as in "_BloodColor"

Total SWAG though.

Otherwise, output the value of BloodColor as the color, for debugging purposes (IDK what your VFX graph looks like, maybe that's what you're already doing)

(I'm making Jupiter, here's what it looks like normally:)

it's prabably because your specular color is white

Hey all, I've been putting together a 2d lit shader for a sprite and it appears the sprite is always black. If I turn off lighting, I do get to see the actual colours of the sprite. I have the light source to a very high intensity and tried moving the light source around to see if it wasn't a normal issue. Not sure what's going on?

(with lighting turned off)

civic fern
#

doesnt matter if its at high intensity, is it within the outer radius?

#

im using custom shaders on 2d sprites and ive run into unity's quirk where you need extra space around the sprite in its sheet if you're going to properly render shaders that increase the size of a sprite, ie, an outline will only render if you have ample space around the sprite
is there a way to do that automatically? like a script or a setting or something that adds a border around a sprite so shaders like that can be used without a manual edit

tawdry saffron
#

Not sure about your question though. I know there's texture padding (which adds extra pixels around the edges of the sprite as it gets bundled into a texture), but I'm not sure if Unity has something like that (I wouldn't be surprised if it did)

Ahh, turns out I needed a 2D Sprite light. Interesting

Not sure if a unity bug, or if i'm doing something wrong here.
I'm trying to assign a sprite to this material, but for some reason its all grayed out. The weird thing is that if I change the shader, I can assign the sprite there. Switching back to the sprite shader after that will cause it to function correctly in game, while not displaying the sprite in the inspector still. I can technically use that as a work around, but would love to double check if there is a better/less bootleg way of doing this. Version 2021.1.4f1

also whats wrong with #include?

iron coyote

AFAIK you have to define these properties manually for each shader. I couldn't find a way to include them like you usually include hlsl programs

#include doesn't work for them, because they are not hlsl programs but unity own thing, I guess?

they are out HLSLPROGRAM tags

the issue is that i am using a custom shadergraph in order to create a "fog" effect where it just fades out into the skybox

#

and doing as an overlaid plane on the camera so that i don't have to make every single object use a custom shader

#

So what it does is it just takes the scene depth and adjusts the alpha of the overlay plane with it

#

in the scene view there the selected plane is just one i put in the scene to be able to see if the actual overlay plane was matching with the skybox by looking through it at the plane placed where it is supposed to fade off

#

as you can see

#

it doesn't match the skybox

patent plinth
#

how many cubemaps in there?

#

just one?

sonic bear
#

just a single one

patent plinth
#

the foggy thing, is it a texture2d with alpha?

sonic bear
#

so basically

#

this part here just takes scene depth directly, and converts it into a gradient of black and white based on the fall off settings that is fed into the alpha property

unknown.png
#

that works perfectly fine

#

here i have been trying to make a cubemap, that will be sampled to match up with how the camera sees the skybox

unknown.png
#

and feed it into the color

#

however i have not been able to sample the cubemap in a way that it aligns with the skybox

#

Here i will show you what it looks like without the skybox cubemap put in

#

olderscreen shot as unity is being slow to load up

unknown.png
#

@patent plinth but the grey "fog" is the scene depth part of it

#

ah here we go, you can see that right here even, the cubemap isn't alligned

unknown.png
patent plinth
#

you mean the horizon wasn't aligned?

sonic bear
#

yeah

patent plinth
#

I'm confused

#

oh

#

you can add an offset from your ViewDirection output

sonic bear
#

offffset it from what?

patent plinth
#

your using Matrix node as well?

#

if so you can just multiply it

sonic bear
#

nope, no matrix node

patent plinth
#

OR do it the easy way, rather than using viewdirection + flip... change it to position + normalized nodes then multiply its position

#

tho I'm not sure if the later would work with your setup

sonic bear
#

i can redo the part with direction and whatnot

#

all it does is feed the sample cubemap into the color of the masternode

#

@patent plinth Multiply it's position by what? also what would i do about the view?

#

this seems to work well

well i do understand how it works in some sense at least

#

i always make a point of trying to understand how whatever i pull from the internet works

#

so that i don't have these kinds of issues

#

hmm okay i believe i have found something that'll solve my issue

#

yep that seems to have solved it, although it is a bit hacky

sonic bear
#

i figured it out

#

and as a result i am going to have a brain anyrism

#

alright how would I go about making a shadergraph object render over everything?

patent plinth
#

You should read about renderqueue, tho shadergraph doesn't explicitly provide this.. you'll find a clue by googling a bit 🙂 sorry can't be any help

sonic bear
#

i figured it out, there was some fanagling on the inside, and working around

#

but everything is working now

#

the issue was that the fog shader was considering this area here "far enough to fade" becuase it was transparent and wasn't included in the scene depth

unknown.png
#

but becuase i was going to add a world boundry in the first place

#

i just created a quick shader that was opaque yet used the same technique to render the skybox

#

so it would get included into the depth

But I think it's unlikely you want to replace all shaders with a toon shader. What about particles? Sprites? UI?

Are you using the built-in render pipeline?

Or URP? Or HDRP?

steady lintel

#

You're always using some render pipeline. If you're not using URP or HDRP, then you're using the built-in one, where you can use Replacement shaders

#

URP and HDRP do not support that feature

HDRP doesn't support replacement shaders either

Ohhhh

#

The built-in render pipeline is the only one that supports it

steady lintel
#

Okay

low lichen
#

How difficult do you think it will be to just put a toon material on everything in the scene?

#

Because this approach will not let you have different materials on objects

#

Which means everything has the same textures

Which is probably not what you want

hmmm, yeah it shouldn't be too hard at all, you think this is the best solution?

I'm having some trouble rotating a quad around a specific pivot point inside a vertex shader. This is my rotation function:

float2 Rotate(float2 UV, float2 Center, float Rotation)
{
    //rotation matrix
    Rotation = Rotation * (3.1415926f/180.0f);
    UV -= Center;
    float s = sin(Rotation);
    float c = cos(Rotation);

    //center rotation matrix
    float2x2 rMatrix = float2x2(c, -s, s, c);
    rMatrix *= 0.5;
    rMatrix += 0.5;
    rMatrix = rMatrix*2 - 1;

    //multiply the UVs by the rotation matrix
    UV.xy = mul(UV.xy, rMatrix);
    UV += Center;

    return UV;
}

I'm passing the vertex position as UV, the pivot offset as the center, and - rotation in eulerangles as rotation. It's rotating the correct way, but the pivot is incorrect..

vernal pewter
#

Nvm, I got it to work. I was mixing up which space this was being calculated in

#

This might be kind of a hard to understand question, but I have a quad that I am rendering again, and then displacing vertices in a shader. The vertices are now skewed, but I want to rotate the skewed quad according to the original quads rotation. But due to the skew (atleast thats what I think the problem is), the rotation is only correct at 0, 90, 180 and 270 degrees. I need to do some additional calculation for the rotation but I'm not sure what it is.

Here is a kind of demonstration of what I mean: https://streamable.com/6w94cl

Hey! https://youtu.be/owwnUcmO3Lw I followed this tutorial on how to make a toon-like shader in unity, and it looks pretty good. My only issue is it's reaction to lights. It only reacts to the worldlight and nothing else. If anyone could take a look at this shader script and show me how I could maybe make it dynamically interact with other light sources in the scene, that would be great. Thanks!

This is happening due to the mesh the sprite is being drawn on. On the sprite import settings you'll see the mesh type, which usually defaults to "Tight" and generates a mesh that avoids drawing fully transparent parts of the texture in order to reduce overdraw. You can change it to "Full Rect" instead, or alter the mesh outline via the Sprite Editor (see https://docs.unity3d.com/Manual/SpriteOutlineEditor.html) to add extra padding for the outline.

Instance ID was added to SG 12. But IDK how to use it. @regal stag has mentioned using custom nodes before.
https://twitter.com/cyanilux/status/1382832863817703426?lang=en

On the C# side, you'd set it up with Material Property Blocks.

Cyan ✨ (@Cyanilux)

I haven't tested it that extensively, but it seems possible to get GPU Instancing with Material Property Blocks to work in #shadergraph via a Custom Function.
Note the empty blackboard & GPU Instancing tickbox also needs to be enabled on the material. Works in v10 at least 🤔

And I'm assuming you mean per-instance properties.

#

Otherwise, all properties are already per-material, basically.

I am having trouble with some shadow stuff atm

#

I have a 2D sprite in a 3D space. The character sprite actually has 2 renderers. One for the player and one to cast shadows. The main one uses a billboard effect to keep looking at the camera. The shadow renderer doesn't have a billboard effect. After separating the lighting and shadow shader, I noticed that the main shader is "transparent" when it comes to shadows. As seen in the image, the shadow of the 3D box is drawn on top of the character, when it is not supposed to.

#

Is it possible to fix this problem or are my options limited because I am using sprites?

topaz cipher
#

billboard effect is your custom script ? or use particle system

Is there a reason why I am getting this error with the Sprite Renderer?

topaz cipher
#

the shader map is base on mesh vertex or pixel, i remember is vertex and when uses a billboard effect is possible not has change the vertex in Fact

or your billboard effect is work in vert shader function, shadowCaster pass not dong same thing

#

Depends on how you achieve billboard effect

I have an idea and I wanted to ask if it's a dumb idea. I want to make my piano keys glow for 300ms. I want to use emission for this. So I thought, maybe I can set the time now on the shader and have it subtract it from the actual time now, clamping between 0 and 1. Can this be done?

#

So every time a key gets touched it sets this time value so the shader can have an emissiveness of 1 again, and go down to 0 in 300ms.

meager pelican
# tranquil fern I have an idea and I wanted to ask if it's a dumb idea. I want to make my piano ...

Well, you didn't say what pipeline, so you'll have to convert the maths to nodes if using SG, but you have the right idea.
So I'd pass in TWO times...the start time and the current frame time (so as to make sure they all sync up, and you don't have any problems with C# time being different from shader-time's _Time, but you can try using _Time.? if you want to and only pass start time).
Then you want a fraction of the 300/1000's that is left.

So it's max((CurrentTimeMS - StartTimeSecondsMS)/300, 1.0)
or
max((CurrentTimeSeconds - StartTimeSeconds)/0.03, 1.0)

Build in variable _Time.x that Unity passes to the shader is scaled to 20th of a second, so you'd need 15 of those if you want. But you'll have to scale CurrentTime that way to match and keep the same units. Or use the float _Time.y and just be concerned about the fractional parts in the expression.

Whatever you do, in the shader you can use an if. Yes an if.

if (emResult < 1.0) {
   do something small/quick to colors for emission
}```
#

And ideally you'd calc that in the vertex stage, and pass it as a flat interpolated value to the frag stage.
And depending on the look you're after, you might want a bloom post processing effect too.

tranquil fern
#

Hmmmm but I don't need an if when using a clamp right? I read that conditionals should be avoided

#

Also yeah sorry, I meant urp.

#

Right now I'm using dotween on the emission color. Something tells me a shader would be better for performance.

meager pelican
#

If the emission color is a parameter, you can set it in C#, but you'll have to do that every frame and reset it if you exceed 300 ms.

Some conditionals in shaders can be avoided with good design, but things like ternary operators and probably clamps and stuff end up still having a condition at the microcode level and maybe even the IL code level.

People get too anxious and clever and don't realize that any expression that has a decision to make has a conditional in it implicitly.

As long as you're not doing some big block of code, and you need the result calced anyway...that if is basically "nothing", particularly since you'd set the condition in the vertex stage if you're thinking.

#

As for other math tricks, you'll have to get the resulting binary code and count cycles to compare them (and it will vary by hardware) or you can just "know" that a simple if isn't that bad. But if you can use a clamp and a multiply, go ahead.

meager pelican
#

And the other thing I should mention is that C# calcs are going to be done once per frame per-object (key), but in the shader it will be once per vertex (if you're smart) or once-per-fragment if you're a newbie and can't put it in the vert().

So it all depends on your setup and specifics. But a GPU has orders of magnitude faster vert processing than you'll probably get with CPU object processing.

But if on the CPU/C#, you can just pass in a 0 or 1 for the result, and then multiply that by the emission color. You should benchmark it each way with a few 1000 keys on your screen. If you're concerned. 😉

tranquil fern
#

Yeah youre probably right. It's not a huge deal in any case. All I have in this scene is the piano

#

And I'm using it to make a video even, so performance is not really an issue. I just don't want to teach myself bad habits

#

My pc is pretty bad ass so I can get away with a lot. I want flying sparks which is not in the scope of this channel. Just mentioning it to explain that my question was probably silly.

Hey I was wondering something and figured I would ask here :

I have a lot of materials in many differents objects. I want to gradually show the objects with a reverse dissolve effect that would be led by a growing sphere in the center of objects. The shader works, it's all cool. But I feel like my workflow is wrong. I am about to change every single materials in the objects to use my shader logic.

I have many different shaders in that scene. I would need to write a custom shaders for all of them and insert my dissolve logic in there and then create a new material and have it use the new shader. That could be easily 40+ materials to make manually + 3-4 shaders to customize. Feels wrong. Is there any way to automate this process to some point ?

My strategy would be to use the dissolve shader for the duration of the appearance. Then switch back to their default material/shader because they are obviously less expensive.

I am doing this the right way ?

Also, maybe my per-object shader is not a good solution too. There is also some objects in the center of the scene that are not to be affected by this effect.

Thank you

meager pelican
#

@torpid sapphireHow's performance?
I mean...
If you're passing in a UNIFORM condition to the object's shader, you can build in conditional "dissolve or not" into the same shader. Still won't be expensive when running "normally". But pass a bool (float of 0 or 1) as a uniform, along with any other parameters.

If/when you do that, ALL CORES in the group will skip over the dissolve code when it isn't needed. Use the [branch] attribute (might be ignored on modern compilers, but use it anyway).

And of course I'd test out the shader-mod first with several hundred objects all fading or not and time it each way. And compare to swapping shaders. Before I edited all materials in the project.

But that beats the heck out of swapping shaders around. Unless you're using stock shaders and don't want to duplicate their functionality.

Just my 2 cents.

Also see excellent post here: https://stackoverflow.com/questions/37827216/do-conditional-statements-slow-down-shaders (top answer)

Stack Overflow
Do conditional statements slow down shaders?

I want to know if "if-statements" inside shaders (vertex / fragment / pixel...) are really slowing down the shader performance. For example:

Is it better to use this:

vec3 output;
output = input*...

torpid sapphire
#

@meager pelican Thank you for your answer ! What I understand from this, (I am not that advanced into shaders just yet, working hard to be tho ! ) is that I should not worry about swapping back the "original materials" since setting a global bool "DissolveEnabled" will give a uniform condition that is the same for every fragment of my shaders so it doesn't break the wavefront, meaning it would do the check for every fragment for each material because the GPU will easily group these calls together. Is that right ? That is super enlightening.

I'd still have to remake their materials but I won't have to keep 2 sets around so that is a cleaner way to do it. Thank you 🙂

#

Also, my understanding is that the gpu will group different materials with the same shaders together, but what is different shaders have the same conditions ?

meager pelican
#

You understood correctly. (first post above)

Unity batches differently, depending on pipeline. And if you have GPU instancing enabled.

For the built-in/standard pipeline, it groups by material. For URP (and I think HDRP) it groups by shader.

That said, it's a good question about params, but in this specific case, at worst adding the bool would break it out into two groups of instanced stuff instead of one group (all other things being equal). So meh. 😉 That's one extra draw call (well, 2x the grouping instead of 1x the grouping), not 100's or 1000's.
So you'll either get 1 draw call for all of them somehow, or 2 one for enabled, and one for disabled. As for the rest of the settings, IDK, good question. Too many pipelines to sort out right now too.
(I think all that is correct)

#

But if you have GPU instancing enabled, you get per-instanced material settings, at least in the built-in RP. For the others, Unity is adding instancing to SG, but IDK what state it is in, a URP/HDRP expert will have to help with that. It can be done by manually editing shaders IIUC.

So that's why having different settings...thus making unique materials...."breaks" batching in built-in, but instancing does not. Because with instancing, it's one material with instanced-data.

#

IDK what happens if you have a uniform variable in an instanced shader not as an instance variable....it's a good question....since it could break batching depending on pipeline. I suspect for built-in, you'd get 2x draw-group calls...you might even just swap the materials, but that's not much diff than swapping the shader.

Now I'm confused. lol. I'd have to try it out.
Batching gets complicated. But it is a good question.
As far as an object's draw performance, my answer stands. But with regard to batching, I'm unsure.

#

And I'd want to know at this point:

  1. What pipeline you're using
  2. What hardware levels you're targeting.
#

Because modern hardware can deal with a dynamic-if when all cores follow the same path and don't diverge pretty easily.

#

@meager pelican thanks again for the answer ! To answer your question I am using URP, primarily shader graphs since I am not that efficient with shader code, especially in URP. And I am targeting mobile iOS and Android devices that runs ARCore/ARKit. It is basically to spawn let's call it a small classroom, with bunch of objects in it. There is a main object that is the main focus that will appear differently but the whole classroom, which is 1m x 1m real world size are the objects I want to show with the inverse dissolve 🙂

So it is a very light scene aside from the AR technology and the facts it will run on lower end devices

meager pelican
#

Yeah, batching in URP is evolving. I'm unsure of the specifics on how setting of a uniform would work other than making a new material for it (like you started with, one of each type for each material).

OTOH, a non-uniform per-instance variable (dynamic uniform...since it is per-object instance, but is he same value for all pixels...the shader doesn't change the value) may work just fine. No cores would diverge. IDK how really low-end/old hardware, but for the mainstream stuff that post above sounded like it would be fine.

How many instances are we talking about?

ornate sierra
#

How would I access a variable on a shader?

would something like this work?

#

Anyone has a clue how some complex procedurally generated terrains blend between textures smoothly? I was trying to pass voxel material index in the uv channel of each vertex to get the appropriate texture from a texture atlas, however, due to uv being interpolated when they are passed to the fragment shader, the fragment colors are all over the place. Is there a well known approach to render multitude of textures on 1 mesh based on some input data?

#

One way I thought of is just to define the uvs for the whole triangle/quad. However, this way the textures won't blend between triangles and it will just result in "blocky" terrain, kinda like in minecraft.

#

Actually, how does unity terrain shader does it? Gotta look into it.

low lichen
#

Unity terrain uses a splatmap, just a texture where each RGBA channel represents a texture and how much of it to blend into each pixel.

kind juniper
#

Wouldn't that mean that you can only have 4 textures blended?

#

Yet you can have more textures on the same terrain.🤔

low lichen
#

It's limited to 4 texture each pass

#

If you add more, it draws the terrain again transparent on top of the previous pass

kind juniper
#

I see. Sounds complicated.

low lichen
#

How many textures do you need?

kind juniper
#

As many as voxel materials there should be. Tens, hundreds? Not sure yet.

low lichen
#

And they're all in one big texture atlas?

kind juniper
#

If there's a better way, they don't have to.

#

I was reading about texture arrays, maybe I can try that?

#

The problem is passing the right texture index into the fragment shader and making sure everything blends seamlessly...🤔

low lichen
#

Your shader will have to sample two times minimum to be able to blend two textures

#

So it needs two indices and then a t value to determine how much to blend them together

#

In most cases, the t value would just be 0, no blending

kind juniper
#

Can't I like compute the blending ratio of textures for each vertex outside the shader, then pass them into the fragment shader to be interpolated?🤔

low lichen
#

Yes you can. And the texture indices can also be encoded in the vertices

kind juniper
low lichen
#

It's not supported on OpenGL ES 2.0 though

kind juniper
#

Can I add it to the default attributes like uv?

low lichen
#

Yes

Oh, okay. Also, it's a urp shader, so HLSL. Is it the same as in CG?

Hey!
I'm trying to create a hex-based map with multiple biomes, and I'm looking for a way to get the texture to tile properly on the hexes while still having multiple textures for different areas.

The way I thought of but haven't tested is simply projecting the texture on multiple hexes at once and cutting it off where biomes change (with a nice transition) to get a tiled and nice map.

However, I don't even know how I would start on this, or if it's viable/there's a better way.

So is it? Do you guys have other recommendations?

Thanks.

(The whole project is based on URP, by the way)

Hey folks - working a on 2.5d game atm (2d sprite in a 3d space), & tryna get a shader sorted out.

Is it possible to have a two sided cutout shader suitable for sprites, that also supports transparency? (Bonus points if the transparency doesn't effect the shadow casting)

Thanks!

And why doesn't this shader work?

sorry i'm really new to Shader Graph

i'm trying to build a simple shader in amplify that looks up a cubemap in the same way as the skybox. my method right now is to invert the view vector and use it to texture sample a cubemap. it's close to the results of the visible skybox, but it's not exact... it looks like it's almost scaled up a little bit. rotations are already accounted for. what am i missing in the maths here?

#

basically i'm building a super cheap fake stained glass material. i've disabled the normal map to make the problem easier to see... the textures don't quite line up, and the scaling makes the cubemap appear significantly larger and chunkier than it should.

I have a post processing effect for rocket exhaust in my game, how would I set it up so it places multiple exhausts in different places?

How would I make it to where if I change a value on the material it only affects the gameobject im changing it on, or would I just have to make different variants of the material

the give you a override on a per renderer basis for material properties

Ok thank you

is there any way to check and see if unity's post processing stack is enabled within a shader? ex. #ifdef postprocessing so i can treat colors a bit different if it is enabled in that scene, would be useful =)

#

I'd just implement some way to adjudt the shaders colors regardless pp being there or not

pliant pond
#

it’s not like anyone would be forced to use it, and obviously you should be cautious of when you use it - it is your project after all, and you would be controlling both the post and shader. you should know what entails when post is enabled, for like you said whether tone mapping is enabled or not

#

a simple use case could be checking whether or not a scene should render a fast bloom done in a post shader in game play or render a fancy bloom during cut scenes or something when post processing is enabled

#

of course scripts or manual work can do all this too, it’s merely for automation and easiness

fervent tinsel
#

IMHO that just sounds like nightmare to manage and is likely to do wrong things regardless the amount of effort one puts to it..

pliant pond
#

Yes but how?

#

We already have unity defined global keywords based on things like platform and graphics api

fervent tinsel
#

Are you using PPv2 or URP/HDRP volumes?

#

Well.. It doesnt matter that much.. Basically you need some script to deal with the absurd complexity that kind of system brings you. Fetch pp components, read their values, figure what which camera they render to, figure what is impact of their current values... Sorry but I just cant see that ending well
