these will help a lot on making SG based ubershaders

I still wish they would let you expose all of the shader graph targets own "master" properties directly

[toxic flume]

Could you suggest any games (for example mobile shooting games) which has nice cool claim/collect button and achievement UI effects? (progress bar,etc.)

[teal breach]

is it not possible to write to SV_Depth using shadergraph?

in the fragment shader

(or whatever the fragment output bit is called on the newer RPs where the output nodes got split into something more like vertex/frag)

[regal stag]

I don't think it's possible in ShaderGraph (in URP at least, not familiar with HDRP)

Shader Graph uses the include files here (https://github.com/Unity-Technologies/Graphics/tree/master/com.unity.render-pipelines.universal/Editor/ShaderGraph/Includes) for the vert/frag shaders, and in most the fragment shader only outputs half4 : SV_TARGET.

[amber saffron]

HDRP output has a "depth offset" option you could use

[regal stag]

If shader uniforms aren't also in the Properties block they are defined as global shader properties which aren't serialised anywhere afaik, so will reset when saving the scene / exiting play mode, etc. Can still have a C# script and set them at runtime (e.g. Awake/Start) though.
While if in Properties then the values get serialised with the Material. There are some limits to that as not all types can be included as properties (e.g. matrices, arrays)

[grand jolt]

oh i see thanks

[sacred patio]

Oml... does anyone know why does this happen when doing vertex displacement? https://i.gyazo.com/11c6dc5fd95de1ea73a112d462a85050.gif

Is it because of the noise?

[tame topaz]

What's wrong with it and what are you expecting?

If you want more wave-like motion, then you just need small waves. It looks like the waves are just really big, and thus affecting the entire plane.

[amber saffron]

Maybe also that the mesh is not dense enough to have wave shapes

[sacred patio]

https://i.gyazo.com/386585063f635fd4a3d697c7359da30b.gif

Yeah I only need a very subtle movement so it's not just a texture on a plane

[royal bramble]

@sacred patio do you have geometry to support the waves?

[sacred patio]

Even if I make the power weaker then the entire plane just raises up and the waves are still huge for some reason

[sacred patio]

Like on what my textures are assigned to?

[royal bramble]

yes

the displacement just moves vertices, so if there's no vertices to move, then it's no wonder it looks the way it does

[tame topaz]

They are moving, but either the waves are too large (not too high, so changing their power isn't the fix), or there's not enough density as Remy said.

Can you show the wireframe for your plane?

[sacred patio]

https://i.gyazo.com/075730b17bdea0cb6ab469ef488a863c.gif

They move in such an awkward manner

I'm using a simple extended plane

So to extend the lava, I extend the plane and increase the texture density

[tame topaz]

You should probably use more vertices, if you intend to have smooth curved waves.

[sacred patio]

Can I increase them in unity? Since I use simple 3d plane

[tame topaz]

No, you want to import your own.

You could use ProBuilder to create one, though, which is available inside of Unity.

[sacred patio]

Tried planes through multiple softwares, this bug kinda shows that the texture itself is moving weirdly, I don't know if it's the mesh that I have to blame https://i.gyazo.com/285f2997bfa4fa30ee5b357d047b87eb.gif

[wary horizon]

            unlitShader = Shader.Find("Universal Render Pipeline/Unlit");
            litShader = Shader.Find("Universal Render Pipeline/Lit");```

In editor, Unlit is being assigned and used correctly... but in build its rendering as pink

And i've got no idea why, does anyone know?

Build

Editor

[amber saffron]

My guess : if there is 0 reference to the unlit shader in your build (no object using it and no reference to an object using it) the shader is stripped away from the build for optimisation

[wary horizon]

oh. yea no object is using it by default, im assigning it at run time

How would you solve that? I dont particularly want 1 random object in the scene somewhere using it

[amber saffron]

Instead of assigning a shader at runtime, I'd recommand pre-building the materials and referencing it somehow in your script to swap the whole material.
The material UI in the editor will enable/disable keyword and features depending on the setting, and this can not be done in the build

[wary horizon]

it'd be useful if you could plug in built in shaders in here

but you cant 😦

[amber saffron]

You can reference the shader asset in a script 🙂

[wary horizon]

is that not what i've done? Sorry im new to runtime shader assignents

        private Shader unlitShader;
        private Shader litShader;
        private void Start()
        {
            unlitShader = Shader.Find("Universal Render Pipeline/Unlit");
            litShader = Shader.Find("Universal Render Pipeline/Lit");```

[amber saffron]

I meant, like a public serialized variable

[wary horizon]

making it public will solve the problem? O.o

[amber saffron]

But still, I don't think it will prevent it from beeing stripped out

[wary horizon]

oh

[amber saffron]

Like I said, the best solution is to use materials directly and swap them, not swap shaders

[thick fulcrum]

you can just use the default plane and tile it or there's some c# examples of how to spawn / create a grid of xx density on the unity Wiki for example

[wary horizon]

can i make a material that uses the unlit shader

or does an object need to use a material using unlit for it to be included in build

[amber saffron]

If you make a material that uses the unlit shader and reference that material in a script, it will be included

[wary horizon]

Ugly but fixed lol

[amber saffron]

Well, the other option is the use resource folders for example

[grand jolt]

#include "Packages/com.unity.render-pipelines.universal/ShaderLibrary/Lighting.hlsl"
#include "Packages/com.unity.render-pipelines.universal/ShaderLibrary/Core.hlsl"

[mild lynx]

How do i use scene color node in hdrp? iv read the documentation and i have used it in urp but i can seem to get it work in hdrp.

this is example of us in URP

for warp effect but in HDRP its Just Showing Black

[steady tapir]

Where did PBR Graph go in urp?

[regal stag]

It was renamed to Lit Graph

[steady tapir]

huh, it was different before

[amber saffron]

Look at the "HD Scene Color", same as scene color node, but take in account exposure

[mild lynx]

@amber saffron i figured it out my shader was not updating my material for some reason but got it fixed

[marsh merlin]

I am using the Universal Render Pipeline 2D renderer. How would I make a distortion shader that I can apply to a plane that distorts everything behind it? Normally, I would use the Scene Color node to get the background and mess with the result, but 2D doesn't support Scene Color.

[eager folio]

Use a render texture camera perhaps

That's what I do for integrating 2d and 3d.

I don't use the 2d renderer though

[fallen oracle]

Hey, so some friends suggested me learning to use Graphics.DrawMeshInstancedIndirect for drawing a ton of meshes at once, I understand this requires a custom shader? However I'm using HDRP, and so I think I'm stuck with using ShaderGraph? Does anyone know if this is compatible, and if so, how I use it/a good tutorial going over it?

[teal idol]

Hi guys, am new to Unity. I just made a simple shader with URP Lit ShaderGraph and a scrolling texture script set up onto the material but they dont seem to work, does anyone know why? I used the same script with the default shaders from either URP and Unity and those works, is there something missing I need to add into the ShaderGraph?

[teal idol]

screenshot for reference

[amber saffron]

If you want to use the mainTextureOffset method, it expects the shader to have a texture with reference name _MainTex and a vector4 containing the tiling and offset values _MainTex_ST.
If you want to use the Tiling and Offset paramemeters that you have curently, you need to change them using Material.SetVector method.

[teal idol]

so something like this?

[proven sundial]

Why cant I plug this into the vertex position?

[amber saffron]

If you've set the "Tiling and Offset" reference name to "_MainTex_ST" I think so

[amber saffron]

I don't see a valid reason for this to not work.
Maybe the "elipse" node was overlooked and is not allowed to be used in vertex stage. Might be worth to report the issue.
If it's indeed because of elipse, you can replace it with other nodes to draw the shape, like distance + step

[regal stag]

Yea, Ellipse node uses ddxy/fwidth for anti-aliased edge

[amber saffron]

Didn't think about this, makes sense.

[proven sundial]

It's indeed the Elipse hindering it. Thanks.

A dumb question, but im stomped. How do I use the uv tile on this generated circle?

[regal stag]

Use the Distance node on the output of the Fraction node

e.g.

[proven sundial]

Cheers Cyan!

[grand jolt]

Alrighty so I have a bit of a problem. I need some help getting a niche shader setup working in Unity (This REALLY is not my department). It would be so so so amazingly helpful if you could @ me here or DM me if you're willing to help me out a bit and explain some of the process involved 😄 Thank you! seriously I'm stumped when it comes ot this area of unity 😅

[amber saffron]

Generally it's better to explain the issue and ask your question instead of asking for allowance.

[grand jolt]

@amber saffron Its to do with outlines and the best way to approach it. I wanted to go for a sketched, "drawn" aesthetic and I wanted to look for any ideas on how to best go about it before committing to a method. After seeing this: https://threadreaderapp.com/thread/1328017722655920129?refresh=1618057433 I was wondering how to implement it. (It seemed a little obscure which is why I thought It'd more appropriate as a side converstation, sorry 😅 )

I've been drawing inspiration from WW1 cartoons such as those of Punch magazine and David Low (Towards WW2)

I had considered the idea that multiple passes with a thin outline effect would produce the "sketched" aesthetic for an outline

But as to shading in this fashion and the general implementation process I'm slightly stuck

[loud remnant]

Textures aren't showing in imported model

My modeler uses sketchup to model and exports as fbx.

When I import the model to unity there are no textures. Please help

[grand jolt]

Make sure the modeller is exporting the .fbx correctly with all the associated textures. They should be able to test this by opening the .fbx in another 3D modelling program and checking

Most likely its not being exported correctly

@loud remnant or ask them to send the textures separately as .pngs and construct the materials yourself

^ That might be the quickest solution actually

[onyx jungle]

Hey is anyone here familiar with planetary atmospheric scattering, I have implemented atmospheric scattering based of some work done by Sean O'Neil' (https://developer.nvidia.com/gpugems/gpugems2/part-ii-shading-lighting-and-shadows/chapter-16-accurate-atmospheric-scattering), whilst it looks nice, I am getting a really annoying point of intensity in the center of the atmosphere that is super bright.

As can be seen here

Any advice/tips would be greatly appreciated.

[amber saffron]

It seems to be a good approach. To implement it you need to use URP. Grab the script at the end of the article, import them in your project, and set the render feature in the URP asset

[grand jolt]

URP ☑️
Script ☑️
The last bit is where I'm slightly uncertain @amber saffron (sorry for the ping again), what do you mean "set the render feature"?

thats really nice though the center is too bright

i like the aura though

looks like atmosphere in my game

you can look up sebastian lague atmosphere on YT i am using his shaders and theyre mostly fine though incompatible with URP/shader editor @onyx jungle

[onyx jungle]

I did also check out his work however I noticed he had the same problem with his atmospheres

they work nicely for the most part

but I am wanting to have caves etc on my planets

meaning it would get really too bright which would look very weird

[onyx jungle]

cheers 🙂

[grand jolt]

oh did you make these planets and caves procedurally

[onyx jungle]

yea exactly

in the screenshot attached I have turned off the planet mesh renderer

just to show the atmosphere bright spot

the atmosphere is fine on the surface but as you enter caves it gets very bright the closer you get to the center, this is the same for sebastian lagues work.

[grand jolt]

thats really nice

[teal idol]

[grand jolt]

can i make this water in hdr shader?

[ivory mortar]

is it possible to use 3D lights in a 2D game?

[glossy hull]

is it feasible or possible to have a shader that can adjust its alpha color based on the objects speed, without basically sending a new material to the GPU each time it happens?

at the moment i have to have a color, set an alpha value then write the new color to the material each frame, which seems heavy?

[grand jolt]

Hi guys, is there a "fast" way with PBR graph to get the world height of the vertex position right under the vertex processed ? (i have a water plane and want to have foam on the places where the water is close to the world floor)

[glossy hull]

i know about that and yet didnt think to use it, good call, thanks

setting a new color was hitting the GC massively

[icy osprey]

how can i get a vector from vertex position to the camera position in shadergraph?

yeah, the results arent exactly as i expected, but at least i know im doing something right

thanks

maybe i will phrase it differently

how do i make it so distance between camera and object has no effect

on how the object is displayed

it sounds so simple and yet i cant figure it out

i thought about adding vector to the camera to the object position node and offsetting it a bit but it just makes a mess, like the object gets stretched and stuff

[glossy hull]

so SetFloat adjusts the material, but SetColor creates a new instance is that correct?

just i cant see you can set aan alpha with SetFloat as alpha is not a property, its part of color/basecolor which is RGBA

yeah i'm going to try that, i was hoping to avoid it

basically i use an asset called HDRP-Outline

and, its okay, it outlines stuff, but i only want it to do so if an object isnt moving

so i had a handy idea to made it nicely fade in and out

_outlineColor.a = 1 - Mathf.Clamp((Math.Abs(car.speed) * 0.2f), 0f, 1f);

but then i had to assign that color to the material, i was doing that every frame

and the GC was like whaaaaat

will do, i'm rewriting the whole routine at the moment as it looks like i was on meth or something when i wrote the original one

[icy osprey]

i plugged screen position node into the UV input of sample texture 2d and now it kinda works how i wanted

except the texture is stretched to fill the entire screen

which is not what i wanted lol

[median gull]

TIL after 2 hours of debugging, HDRP color buffers are 16 bit. 4 bit per channel.

HDRP full screen custom pass floats are 4 bits wide / presision. So much time spent trying to figure that out.

[glossy hull]

okay i think i got it sorted, the HDRP-Outline asset was causing me a problem as it was assigning propertyblocks and resetting up the materials etc each time the color was changed

i guess it wasnt designed with runtime changes in mind, at least not each frame

i ended up removing all that code, creating a new material on startup from the old one, then go through each sub object and replace the material with my new one, so i now have 8 objects each with its own cloned material, now i can setcolor on each frame and it seems much faster than before

still feels dirty, but we'll see

[median gull]

Same material, same mesh, roughly the same position. Consider making sure your shader / material is SRP Batchable. Will make it even faster.

[glossy hull]

not sure how to tell with this shader

[median gull]

Eh, it's a tiny improvement for a lot of work. Just ignore the SRP batching if you dont know what it is.

[glossy hull]

i know what it is, i just cant seem to find the screen where it tells me, which is odd i've seen it loads of times 😛

[median gull]

Select the shader file itself. It should be something like this

[spice iron]

this is prob a stupid question seeing as google didn't yeld any results, but is there a dictionary/hashtable structure in hlsl that I can use in compute shaders?

[median gull]

SRP Batcher compatible right at the bottom

If it isnt, you'll get something like this

Where it complains

[glossy hull]

got it, thanks

not compatible

not sure what that is, i likely dont need it

i'll mash it some more

well its defined, it complains if i remove it

think i got it

says compatible now

[median gull]

Beyond that, you'll have to hope that Unity uses it. Whether or not it's being batched is complete magic.

[glossy hull]

cant say its made any tanglible difference

but it was handy to know how to make it compatible 🙂

[median gull]

Yea, very small benefit. Only really is visible for tens to hundreds of identical objects.

[glossy hull]

oh

[median gull]

Like trees in a forest.

[glossy hull]

well, there is only one of each

thats not true actually i supposed it has subobjects

[median gull]

Oh, then no. Well, if you need to outline the same tree it'll help.

[glossy hull]

all the subobjects also outline as they form the stencil or whatever

so perhaps they now batch

[rugged verge]

Hey Carpe, thanks, the solution worked I forgot to say. 🙂 But I later refactored to using SetFloatArray (I didn't research enough to know that materials can be set with float arrays), but the old solution using texture2d was quite educational and a fun solution anyway 😄

[obsidian folio]

Hey, I'm new at Unity, is it possible to make a Material/Shader like this one? https://archstylemx.tumblr.com/post/129719764816

[shrewd mist]

Is it possible to use a Unity transform inside Shader Graph?
I want to use the scale

But using the position would also help

[meager pelican]

One reason for using the texture is that the texture sampler processors on the GPU will interpolate "between pixels" so you don't have to play games with floatarry[x-1], [x], [x+1], figure out where you are, and calc a value.
BUT...depending on your needs, if you want to move in discrete steps or you otherwise can just do a normal lookup into an array, cool. 😉
Glad you had fun. 🙂

It would be an interesting test to see which is faster, since "the math" is sampling the array just like the sampler is sampling the texture, but the sampler is keeping track of things like derivatives as it goes. Results will probably vary based on sampler settings and also on methodologies. Math is favored over sampling, but reading array[x] is a form of sampling.

[grand jolt]

So after a lot of work and a reset I've gotten here . And I'm just plain confused at this stage 😅 The script uses a material called: "blitmaterial" and I've passed in a green transparent material (which is why there's green on the screen) But i can't figure out why its being shown in this way. Some help would be appreciated. I used both scripts attached in his guide and created a hacky blitsettings class because his was missing. Please DM or @ me if you think you can help.

[fast oar]

@civic holly I am pretty sure Materials don't have a GetComponent() method ?

Do you want to set the value for 1 material only ?

[civic holly]

yes

[fast oar]

You can simply do mat.SetFloat(...) where mat is a public Material that you have asigned in the editor

[devout quarry]

Or alternatively, you can get the material from the renderer component

Also as a side note, never do get component in update, do it once in start

[civic holly]

thanks for your help. i have to go but will return in an hour and try your suggestions.

[devout quarry]

Yes

[elder spruce]

its darker than the art i made

uhm how can i make it so its all the default colourt

like no shading everything lit up

[devout quarry]

Is the shader on it 'lit'? You might need to put an unlit material on it

[elder spruce]

where do i check that?

[devout quarry]

This is a 3d object? Or a sprite? Click on it, in the inspector you'll see a material assigned to it

[elder spruce]

its a plane with a sprite texture

also why does it highlish in the bottom left?

[devout quarry]

Yeah there, the 'new material' in the renderer component, click on it and you can set the shader type

[elder spruce]

then it becomes a square

[devout quarry]

What shader was it originally and what did you set it to?

[elder spruce]

what does that mean

i think its sprites/default

then i set it to unlit/texture

i got it to work but now it just takes up the bottom left

nvm tiling

[crimson stone]

i'm new to shaders and currently experimenting with hdrp post process shaders, can someone tell me how i get the camera's normal vector? nothing i've found online works

@crimson stone the camera is a point so doesn't have a normal vector?

You mean the normals of the scene, as seen through the camera?

Doesn't HDRP generate a depthnormals texture?

[crimson stone]

right, the camera view direction then

Nope, I did texture paint in blender n saved it as one image (skin, lips and shadows)

But only skin colour is shown

Same with the eyes, they should look blue with white dots

[lost lichen]

need to add vertex color to shader probably

[lapis grove]

If it's saved as one image why are we seeing several?

[devout quarry]

Yes, you sample scene color, add distortion

[brittle berry]

tests, only one is added

[lapis grove]

Do you have multiple UV sets on the model, and/or have you chosen the right UV set in the shader in Unity? I've occasionally heard of Blender users ending up with a few for some reason

[brittle berry]

I have multiple, like, one for the shirt, one for the pants, Im pretty sure I have chosen the correct one because Ive got the same problem with the shirt and pants, and I only have one image for each of them

but its strange because my past model didnt have that issue and its the same avatar but with a blindfold lol

Hello everyone, I made a crack in the ground by following this tutorial which uses the stencil buffer. It works perfectly, but the problem that comes to me is that the hole is still visible through the mountains ... Does anyone have any idea how to fix it ? 🙂
Thank you 😉

https://docs.unity3d.com/Manual/SL-Properties.html i don't see how to include an array in properties of a shader, so how do i achieve sending an array to my shader?

[fossil sedge]

I dont know where to post it so i might as well try it here. I'd like to make some kind of a filter that would make a 3d game look as pixelart (example here https://www.youtube.com/watch?v=ERA7-I5nPAU) . What would be the best way to approach such a task?

[sinful shuttle]

Anyone know of a realistic looking grass shader which works with VR, can render a nice lawn, and generates actual geometry for the blades so that it looks good even if your face is right down in it? Most of the grass shaders I've found use "shells" like most fur shaders do, and such methods look terrible up close, and in VR.

[thick fulcrum]

it's possible, Aura3 for URP is in the works but not sure of a timeline for when it's available.
If you are confidant with shaders you could probably roll your own

[lean lotus]

Are there any general tips/resoures for optimizing compute shaders? I am making a ray tracing compute shader with BVH traversal, and im just wondering if theres any general optimization tips as I cant find much on optimizing compute shaders on google
Also is there a way to return something like rays/second? aka returning data from the compute shader once its done rendering?
Also what are my options for debuging/profiling/performance stats of compute shaders in unity on mac?

[terse shard]

Is there a way to remove the extra input fields when adding a vector2 parameter in shadergraph? Seems awfully redundant to have two extra fields that have no purpose...

[brittle owl]

what fields?

[spring field]

Good Evening. I'm trying to make a billboard shader for a sprite object. I'm basing my self off of a tutorial and it seemed to work at first, except it seems to sometimes clip on the mesh and on top of that completely ignores angles sometimes, and when there's many only a few render.
I am uncertain on why this error occours.

First two issues and shader graph are in the screenshot.

[sleek condor]

@spring field, I'm really sorry but I have not understood your problem =/

[sleek condor]

Anyone got an idea? please

[teal breach]

Might be worth clarifying a bit exactly what you want. I think there are generally two parts to this - the pixelisation (eg rendering 3d objects at lower resolution), and the appearance (cel shaded, line detection, color grading, etc). T3ssel8r is friendly on Twitter and you could enquire there aswell. To pixelise, either use a method that renders the entire screen to low res (see eg madalaski's videos), or one that does it per-object (see eg my method here under attempt 3 https://medium.com/@elliotbentine/pixelizing-3d-objects-b55ec33328f1 )

[thick fulcrum]

assuming this is set to transparent, it will not write to depth by default and this can cause z-fighting / rendering order issues. As your using shader graph one of the easiest solutions is to use opaque cutout and dither the alpha (transparency). However this may not give look you desire and a different approach maybe required.

[toxic flume]

One question, finally it is suitable to use half,half2,.. instead of float,float2 for custom properties in shaders? (Mobile devices)

[shadow kraken]

Where you don't need the precision, use halfs because they use less memory

[toxic flume]

Because I have read some devices work better with float?!
@shadow kraken

I think instead of int, yes but not half or fixed?

and can't I change keywords (multi compile) in the inspector? only from a script I can enable or disable it?

[shadow kraken]

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

[regal stag]

You can create a Float property with the [Toggle(keyword)] drawer to have control over it.

[amber saffron]

Some keyword can be bound to material properties using the built-in property drawers : https://docs.unity3d.com/ScriptReference/MaterialPropertyDrawer.html

[toxic flume]

and what about converting half to float or half to fixed?

for example my color is fixed4 and somewhere it is multiplied by a half variable, power,...

[heavy pebble]

Hey, I have two questions both revolving around surface painting, in how this demo tut does it : https://www.youtube.com/watch?v=YUWfHX_ZNCw .

After browsing through the provided source I see it involves a basic approach like : create a render texture of each paintable object, and then (I guess) on painting, edit that render texture itself via the CommandBuffer API.

Q1) Is there a ballpark on how expensive this is? Seems quite functional in the demo project, but I've been using Render Textures a bit for portals and they are very expensive in that usecase.

Q2) This process also involves each object having the same material on it. This works pretty well for their example project as they are using the same mat for testing, but how to "extend" this behaviour onto multiple materials? I guess my question is it possible to inherit shaders? Like, I would like to extend HDRP/Lit to include this too.

[shadow kraken]

Q2) This is not very different to normal, instead of using a standard shader, you make a similar shader which also has support for this feature. You can make a subgraph for the painting section to organise better and use across different shaders

Q1) I don't have a good answer for but I think at least that you can say that the scalability isn't very good, considering it's an extra texture per object. The list of options at the start is good, cause it gives some alternatives. I've used lightmap UVs for this before, which can be more optimized, but then you run into issues with dynamic objects.

[thick fulcrum]

in Q1 you reference portals as an example, assuming you are rendering a view through the portal (using a second camera to capture the view). It's the second camera doing all the extra rendering which is costly, no so much the Render Texture. If that's not the use case then disregard 😛

[hearty wasp]

I want to make coastal waves for a water shader, ones that go towards the shoreline mesh. How would one even "get" this direction of the coast mesh in order to project textures in that certain direction? Or does it have to be done in UVs somehow?

[sleek condor]

For me, the best way is to use vertex painting to give to your mesh the good direction. To get your direction in your shader you can do the same trick used for flowmap .

Tutoriel flowmap : https://www.youtube.com/watch?v=SA6Y3L-X0Po&ab_channel=PolyToots
You can make vertex painting with the unity package proBuilder or polyBrush

[heavy pebble]

@shadow kraken That does seem to answer my questions. Thank you
@thick fulcrum I see 😆 That is indeed the usecase

[hearty wasp]

Thanks for the suggestion, I also came across this twitter thread by Cyan, https://twitter.com/Cyanilux/status/1252298028607774721?s=20
also very useful!

Cyan (@Cyanilux)

Hey all, wanted to share some info about how the shoreline shader is done. (This is a slightly simplified version).

But I'm looking for a way to do this without any manual input (no manual uvs, baking, vertex painting,etc), if that's even possible?

[thick fulcrum]

I experimented in this area, you need to consider what information you have or can generate. Which generally boils down to a depth map, you can use this to generate motion towards shore, however I could not get it to look very good. Mileage may vary, it's very uniform even broken with some noise repetitions seemed obvious and not ocean like.
I've yet to see any implementations which are fully automatic, just pick which is most manageable for you and use it imo 😉

[hearty wasp]

Good advice, thank you! From what I've seen it looks like it's either doing the effect in a single direction or doing manual work with UVs etc.

but that's not gonna stop me from experimenting a bit, see if I can work something out

[long rune]

Does anyone have an idea on how to solve this issue?

[shadow kraken]

Are you generating this mesh at runtime @long rune?

[long rune]

Yep

[shadow kraken]

You either need to change your UVs or use a triplanar shader that doesn't rely on UVs

[long rune]

That won't work for me since I need to be able to rotate my mesh

[heavy pebble]

Is there a guide/standardized way for converting URP HLSL shaders to HDRP?

I ask ^ because, these 2 shaders : https://hatebin.com/vclvphkraw seem to work in URP, but not in HDRP. I have no idea what they do 🥴 I can only imagine that it needs some extra lines to work in HDRP

[shrewd echo]

has anyone ever come across a URP Vertex color shader that nicely fades alpha? I made one in shader graph but it does more of an alpha cutoff effect than a nice fade out.

[hearty wasp]

if I had to guess you don't have your shader set to Transparent

can be done here in the graph inspector settings of your master stack, then just use the "Alpha" instead of the Alpha Clip Threshold

it should then fade out just fine

[shrewd echo]

you are correct. I did not 😛 - noob mistake

[hearty wasp]

all good! glad I could help

[shrewd echo]

ok - follow up because I thought for sure this was easy. I'm writing vertex colors to a custom mesh. This worked in the built in renderer with a particle shader so I know I'm doing that correctly. With this new shader I don't get colors showing up. (But the alpha is now displaying correctly.) Any tips on what I might be doing wrong?

[hearty wasp]

as far as I know Vertex Colors can't really contain an Alpha or affect it directly like that

so you'd have to control the Alpha in a different way, something as simple as a Float property perhaps

1 = opague 0 = transparent

[full jasper]

Hey, is there a way to access pixels on the moniter? What i'm thinking about is a shader that uses the color of the pixel the cursor is over.

[shrewd echo]

i think it can contain alpha because the alpha part is working - but the color info is not. Its only showing up white on my custom mesh...

[low lichen]

What Emission Color are you giving it?

[shrewd echo]

white - it just to help see the mesh in the dark. I've already tried without it and it just shows up black. The alpha does fade off but the colors I assign the mesh when creating it do not show up

[low lichen]

Emission at white will just make it white

If you want it to glow in the vertex colors, then plug the vertex color into emission instead of albedo

[shrewd echo]

Thanks @low lichen. That did the trick.

[old otter]

Hey. I can't seem to make FindKernel work in builds. Works fine in editor though. Any idea?

[real venture]

Hello, this effect here where the camera distorts: (https://youtu.be/arqRQW8-Ugk?t=56), (at 0:56) was this made with shaders? Just wondering if I'm heading in the right direction.

[wheat quail]

I finished brackeys grass shader tutorial. So my issue now is that ALL my grass sways the same way at the same time. I could just offset the 'windDensity' a bit but what I'm want to do is change the seed of the gradient noise if thats even a thing(?)... is there a way to randomize the seed of the noise?

[real venture]

As far as I know (and admittedly that isn't much), if you're using the same material for every object, it'll be using the same single configuration of that shader. That's based on seeing 3 different grass wind shader tutorials, and every one had all the grass moving uniformly. Aside from using multiple shaders for different parts of grass, I'm not sure.

[wheat quail]

k, so i found a random range node, n it has a seed variable. I think if I at least give different grasses a different seed I should be able to come up with a decent random effect

[white smelt]

how do i get view vector in unlit shader?

[white smelt]

is there anyone?

[wind sigil]

is it possibele to get the terrain depthtexture when terrain has "draw instanced"? I tried turning instancing off/on in OnRenderImage but that doesn't do anything. Only if its completely turned off does my simple shader render the right image.

[wet geode]

any idea why this double sided shader does this thing? It seems like the opposite side isnt aligned to the top side

ah nvm. It seems to be something i did in speedtree

[wind sigil]

switching to deferred rendering fixed the problem, don't even need to write any code. ez life

[grand jolt]

Hello,

I'm new here and have a problem with a shader which I can't solve.
In this shader I want to use a render texture from a camera as albedo or base color including its transparency.
Additionally I want to mask this texture with a separate black & white mask so it is only projected on the parts of the model where the mask allows it.

I am no shader programmer so I'm afraid can't solve this by myself.
Ideally it should work as the standard pbr or the autodesk interactive shader with the additional mask.

Has anyone an idea how to solve this?

[median gull]

First question, Shadergraph or HLSL?

[grand jolt]

HLSL

[median gull]

Right, I'll assume you already know how to hook it up to Unitys various SRPs. The actual shader is pretty simple in theory. In practice, it depends on the settings.

[grand jolt]

Yes, I think know how to hook it up.
I just have no idea of shader programming an no programmer at my fingertips 😟

[median gull]

Camera color buffer doesn't have transparency, technically. The color pyramid, the actual camera output, does not but CameraColorBuffer does and that is set to 1 at first read until you change it in a fullscreen shader.

That requires your camera settings to be RGBA32 as well. Simple setting and simple fix if your HDRP. URP, no clue.

Camera base color, simple. Copy the camera color buffer into a render texture. From what I see, you already know that so I'll skip ahead.

[grand jolt]

Well I simply set the background alpha of my camera to 0 and it worked for me.

[median gull]

Hrm right, camera clear color can introduce alpha. That also works.

A black and white mask will be slightly more difficult, where will this mask be rendered? On the material itself or passed to the shader you will be using?

[grand jolt]

Here is a Screenshot of my Test.
The camera projects the models on the jar.
I want to restrict the projection on specific parts of the jar with a mask in its shader:

[grand jolt]

It will be rendered on the material of the jar with the render texture as albedo.

I thought of a texture input in the material where I can select the mask texture

[median gull]

Okay. 3 textures. One is the render texture output of the camera looking at the various objects. A second is the Black and White mask. The third is the jar's original material. All three textures are to be placed on the material (and connected shader) itself.

Inside the shader, sample all three textures in a frag shader. The resulting return color will be Lerp(RenderTexture, JarTexture, BlackWhiteMask.r)

[grand jolt]

Well the jar has two materials.
One is the glass and one is the print laying above it.

[median gull]

Yes, and the mask you'll be using to sample the lerp value from.

[grand jolt]

In shader graph in URP, what's the best way to invert an object's colors, including its shadows?

@median gull Hm, I'm afraid I have no idea how to do this as I have no programming skill.

[median gull]

Although if you want the transparency of the rendertexture to reveal the jar texture, you'll then need a second lerp after that. Lerp(RenderTexture, JarTexture, RenderTexture.a).

[median gull]

I'm on my phone on my bed or I can type out the entire shader for you. Not too difficult.

[grand jolt]

That would be very helpful if it would be possible

[median gull]

The entire Fragment function in the shader will be 6 lines.

1. Sample RenderTexture using Frag UV.
2. Sample JarTexture using the same UV.
3. Sample BlackWhiteMaskTexture using the same UV.
4. float4 color = lerp(RenderTextureColor, JarTextureColor, BlackWhiteMaskColor)
5. float4 outputColor = lerp(JarTextureColor, color, color.a)
6. Return outputColor.

Theres more boilerplate. I dont remember it from the top of my head but it's the same for every shader so you can probably copy paste it from google.

[grand jolt]

Thank you.
I'll see if I can wrap my head around this 😄

Started working on a shader graph shader to invert an object's colors, but I'm not sure if there's a way to get the scene lighting on the object and invert that as well. Is there? Do I need a custom script for it?

I thought maybe there's a way to get the raw PBR properties in shader graph and invert some of those?

[low lichen]

No, Shader Graph doesn't expose any of the lighting calculation it adds on top of the master output. It'd be nice if there was a way to modify the final color before it returns it.

Surface shaders in the built-in render pipeline has that feature.

[grand jolt]

dang

[low lichen]

If you're okay with modifying the generated shader code, it would be pretty easy

You could also probably make a transparent shader with a blend mode that just inverts the pixels behind it. Although, that would only work on opaque objects. If you did that with transparents, it would stack, inverting already inverted colors.

Like this:
https://www.reddit.com/r/Unity3D/comments/1onw43/invert_colors_shader/

Nice thing about doing it this way, is that it can be applied on top of any object using any shader

You don't have to replace the object's material with your own custom invert color material.

It's like a post processing effect, but applied locally per mesh, instead of full screen

[true relic]

Some good recommendations for learning shaders in unity? Need some faster tutorial (to learn in week or two maybe)

[grand jolt]

@low lichen Ended up being able to modify the Toon Shader V2 in Lux URP Essentials to be a true inverted shader! 😄 (second image is inverted in GIMP lol)

[teal breach]

It's a very large topic! If you only have a week or two, it would be better to describe what you are trying to make and people might be able to give more focused suggestions (eg specific tutorials to follow)

[true relic]

Doing on 2d texture application shader trying to speed up proccess,somehow that GPU can process it faster, get as much as possible fps.So something about 2d texture quad shaders

[white smelt]

how do i get view vector in unlit shader?

[whole shadow]

pardon im trying to use the shader graph to get the screen posisition and then i wanna divide for the xy value with w, but for some reason i end up with a pink error state i guess

am i not understanding something or is there something i missed?
can w be 0 and that be the reason for this issue? but even then what can i do as an alternative?

[regal stag]

Shader Graph already handles the division by w for the Screen Position node

[whole shadow]

okay that explains it i guess, but how should i go then cause im trying to do apply screenspace texture onto an object in world space, while using the cameras direction

ive seen some solutions online but i cant seem to make it work properly

[whole shadow]

@regal stag (just in case, sorry for pinging just forgot to do a reply so i mark it like so)

[regal stag]

If you're mapping a texture in screenspace, using the camera's direction doesn't matter as it's already aligned to the screen. Just use the Screen Position node as the UVs into the Sample Texture 2D node.

It'll be stretched due to the screen aspect ratio though, so you may need to multiply it by a Vector2 with X axis as Width/Height from the Screen node and Y axis left at 1. Or maybe use the "Tiled" mode on the node.

[teal breach]

I'm still not entirely sure what you mean - like an image filter or something like that?

[true relic]

I meant by that image processing algorithms , they can be slow per each frame, i am trying to figure out how to use shaders , i know they can raise you performance.

[teal breach]

ahh ok, like a post processing effect applied to the whole frame?

[true relic]

Yes technically postprocessing with shaders

[whole shadow]

wait doesnt it matter since im trying to apply this on a gameobject mesh?

[long rune]

Can someone help me splice 2 shaders together?

[rain fable]

@long rune Make them subshaders, then make the output of one the input of the other?

[long rune]

I have no idea how to do that

[rain fable]

are we talking shadergraph or plain hlsl here?

[long rune]

hlsl, I have a triplanar shader that i want to combine with a uv rotation shader

[rain fable]

ah dang, in shadergraph it would just be a few clicks

so, i suppose you want to write a new shader

that combines the two you have

because you can only have one shader active on a gameObject

[long rune]

Well yea, but im not good at shaders so

i have the 2 shaders, just donno how to combine them

[rain fable]

i see

well, try to figure out what they do, then do it one after the other in the order that makes the most sense

if you're at a complete loss, just copy the payload code one after the other into one shader, see how glitchy it is and go from there

[vale cypress]

Hi is there any known issues with compute shaders and older hardware(running a i7-2600k and a gtx770). Can't seem to write to multiple textures from a compute shader

has anyone ever tried a 2D rigged sprite imported as a PSB file and had a shader in 3D Space (via the 3D Render Pipeline. Not the 2D one)?

I tried to do some approaches based on some examples I found but they used a single sprite so there weren't issues. Since my sprite is a bunch of connected parts all in a very similar position on the z axis, things flicker in the overlap. Is there a way with the shader graph to mitigate that?

i can share the shader so far in a couple of minutes.

Hi, what is the best resource to learn about HLSL with URP on Unity 2019.4.15f?
I've tried to look in the documentation, but it's all written with Cg.
What I am looking for is: _MainTex_TexelSize, _WorldSpaceLightPos0, _LightColor0 and ShadeSH9.

[regal stag]

There's not many resources. I have this : https://cyangamedev.wordpress.com/2020/06/05/urp-shader-code/ (and working on rewriting it too), but if you're looking for something specific it's usually best to look at the ShaderLibrary source.

The texture's _TexelSize variable hasn't changed. For light direction/colour you can use GetMainLight() from Lighting.hlsl. For ShadeSH9, use SampleSH(normalWS) instead.
I think 2019.4 would be URP v7.6, so see : https://github.com/Unity-Technologies/Graphics/blob/v7.6.0/com.unity.render-pipelines.universal/ShaderLibrary/Lighting.hlsl
(You'll also need #include "Packages/com.unity.render-pipelines.universal/ShaderLibrary/Lighting.hlsl" in the shader to make use of those functions)

[regal stag]

Your Smoothstep node is set up differently.
You should also make sure the Depth Texture is enabled on the URP Asset as that's also required, and the graph's surface mode should be Transparent.

[iron reef]

oh yup

had it going into the wrong thing in smoothstep

thank you

and depth texture wasn't enabled but I don't see any difference after enabling it, but it seems to work somewhat now

[regal stag]

Might work in scene, but Depth Texture will need to be enabled for it to work properly in Game view. It's possible some post processing or the camera is forcing it on anyway too.

[iron reef]

It still looks different from the video's however

[regal stag]

The Edge2 in the smoothstep should be 1 to match Brackey's one. Probably also don't need alpha clipping enabled.

[iron reef]

[vocal thistle]

no

[spring frost]

I wrote a shader that uses a halftone circle or crosshatch pattern in screen space to dither gradients (just an easy smoothstep on a distance field based on intensity).

Problem: The screen-space-part actually makes it feel like a screen door effect, I'd much rather like it to be in object space like if I were moving a pop art poster in front of myeyes, but I also don't want the dots to be skewed as if they were in tangent space.

What could I look into here? Triplanar shaders? I suppose at oblique angles this is perhaps less than trivial. (if the dots are always orthogonal to the camera, I'd need to gather intensity from depth or something)
https://imgur.com/GOKac4h

With triplanar or in tangent space, this is as close I get.

[thick fulcrum]

For my original suggestion there is a detailed article which explains it quite well: https://danielilett.com/2020-04-19-tut5-5-urp-dither-transparency/
However it may not fit in with your look / style.
I'm no expert, I've just come across this problem myself before. It is an age old problem, if the above does not meet with expectations just searching the internet will bring up a few alternatives.

The most efficient is probably on the shader, if the UV animation can be calculated on the vertex stage.
But you will have less control over it.

But unless you have hundred or thousand of similar things to animated, I think CPU is good.

[toxic flume]

What about In sprite animations?
An animation with key frames

[red mason]

Can i take the depth buffer of 3 different cameras, do some crazy modifications, composite it back together and then injecting it back into the render process for it to be used to render the scene.... or am drunk and i should go home?

[amber saffron]

Key frames are on CPU only. You could however re-code the animation some way in the shader, but you will loose the nice control that you have from animator components and animation assests.
Like I said, unless you really have a bunch of those objects, CPU is good.

[amber saffron]

Technicaly, nothing prevents you to not do it, but I wonder what is the use case here 😅

[red mason]

The use case is i'm dumb XD I just realized i can enable Depth writing in the shaders already so i don't have to make anything so complicated lol

Mh my issue seems to be of a different nature, maybe it has to be with the rendering queue

So

Maybe i can get some help, here's the deal

I am taking a texture from a custom pass and a specific camera, then i'm using that texture to generate a clipping mask for my main shader

the problem is when the model with the main shader moves the mask lags behind

Any ideas/suggestions on how to avoid (if it's even possible) or mitigate this issue?

[amber saffron]

Well, the obvious solution is to order you rendering so that the custom pass & specific camera is rendered before the masked object

[red mason]

That makes perfect sense but i don't know how to do that.... also wouldn't the depth pass being taken always happen before the rest of the shaders being rendered?

Oh!

I can set up the custom pass before rendering and that solved my issue 😄 thank you so much @amber saffron !

[restive radish]

Any tutorial on how to make billboard shaders?

Hey, how can I get create 2d shader graph, my project is already using 2d renderer but I don't see an option to create 2d shader graph

[regal stag]

Under Shader -> Universal Render Pipeline there should be Sprite Unlit & Sprite Lit graphs

[soft nova]

thanks!

[toxic flume]

Have you used codestream?
My problem is this warning

[grand jolt]

Hello there 👋 Currently trying to project normal decals to add metal deformation onto my assets, I'm experiencing a hard edge where the decal starts, when the normals are not aligned perfectly (see video related) I've tried adding a mask which takes care of the hard edge but the normals are misaligned so still very visible, I'm new to shaders and HDRP and would like to know if it's possible to rotate the decal normals based on the object it is shining on. Ideally the projector would add/multiply/matrix-transform normal information onto the model's base normals

[small lichen]

I'm looking to save a depth map and another image (same viewport) based off of the depth map, but inverted and scaled. This would happen continuously throughout a simulation so I'd end up with hundreds of each type of image. My initial thought was to have a compute shader to get the second image, but would it be more efficient to just have a second camera with the same viewport and a different fullscreen pass?

[dull lintel]

Anyone have any thoughts on how I could get a shader to leave a masked portion of my model unlit (just a black void) while still doing the full PBR lighting workflow for the rest of the model? Would I need to essentially recreate the PBR flow as my own shader graph so I could selectively ignore it? This is in URP FWIW.

[grand jolt]

is there a way to program a shader that applies chromatic aberration to objects inside the worldspace of an object with that shader? f.e i have a sphere with that shader and i shoot a projectile through it as soon as the projectile hits the sphere the aberration kicks in and splits the projectiles colors if it exits the sphere the color split is no longer there
is there a way to produce this ?!

[amber saffron]

It's not possible currently to deform the underlying normal with a decal. The best thing you can do is to use a mask on your decal to mask out the deformation shape.

[amber saffron]

The easiest is probably to use albedo, smoothness & occlusion = 0 for the masked part, it should be full black.
Else you can use alpha clip to display only the PBR part, and a render feature with an other unlit shader and invert alpha clip to display the rest.

[amber saffron]

Shadergraph ? You could do that with the scene color node.
If built-in renderer, look at grab pass

[dull lintel]

Albedo/Smoothness/Occlusion=0 seemed to have the area still pick up direct lighting for me, but I can give it another shot. For the second option, how would I stack the shaders like that, or select between the two flows? Is there any way to do it in a single shader(graph)?

[amber saffron]

Not in a single one no.
You draw the object with your regular shader, create a second one that renders unlit black for the inverse of the mask, with the same input parameters if needed, and set it as override shader in a render feature in the URP asset

[grand jolt]

I'm trying to make bloom to a game, but for whatever reason my sprites texture gets all messed up when I use a shader graph

I'd appreciate all pointers what might be wrong

[regal stag]

The previews just don't show alpha so they can look a bit strange. To fix it in scene/game you need to put the A output of your texture sample into the Alpha port on the Fragment section though.

[grand jolt]

oh

that was easy

@regal stag thanks

[lean lotus]

Hey does anyone know any ways of debugging and/or profiling compute shaders on mac? im trying to optimize this, but I dont know any way of at least returning values back from it(its purpose is raytracing, but idk what specific parts or general parts are tanking its performance)

[dull lintel]

Looking at this again, it looks like the Renderer Feature takes a global material (not shader) for all objects, but different objects have different textures and properties and the like. How does the renderer feature scale in this case? Do I set a MaterialPropertyBlock on each object with what texture it should use, or is there a better way?

[eager folio]

If you give the property/texture the same name it will be reused for different shaders

[dull lintel]

Ah, good to know, thanks.

[eager folio]

Though actually not sure how that works with material replacement with a render feature...

I mixed lit and unlit parts of my shader using Cyan's lighting nodes. https://github.com/Cyanilux/URP_ShaderGraphCustomLighting

[dull lintel]

Yeah it doesn't actually look like it's replacing the properties.

Trying the MaterialPropertyBlock method next to see if that works.

[eager folio]

Speaking of, @regal stag did you ever write more about the urp terrain blending? That was looking really interesting.

And twitter is a pain to search

[vocal thistle]

how do i make particles have glow?

[lapis dome]

[edgy hull]

is it possible to reset the sine value of the time node in the shader graph editor thing?

[green nebula]

Hey guys, I have this grid shader that came with an asset pack. I want to offset it, but when I move the gameObject to which the material is attached, the texture stays in place. I need it to offset by 0.5 in X and Z (World space values). How can I do it? (I have no experience in shaders)

Or maybe just disable the texture moving

[elder wagon]

Does anyone here know if Compute buffers with ComputeBufferMode.Dynamic/ComputeBufferMode.SubUpdates is unsupported on Direct3D11? I have a situation where I want to use dynamic compute buffers, and the code I have works with dynamic compute buffers on Vulkan, Direct3D12, but not Direct3D11. Note, it works on Direct3D11 if I use ComputeBufferMode.Immutable.

[grand jolt]

Hello All
I want to create an outline shader (pretty similar as what selecting an object in scene view looks like), that is supported in URP
can you point me in a direction on how to do it? or if there is an implementation available?

[grand jolt]

how would I go about adding multiple spritesheets to my bloom shader? currently its just set to work with my idle animation.

[regal stag]

Nah, was just 2 tweets on it. https://twitter.com/Cyanilux/status/1362168584592621572
The technique I was using used an orthographic camera looking down, capturing depth and the lit terrain texture (but without shadows). The blending could then be put into the Emission slot on the terrain shader.

It didn't work with ambient / baked lighting though. I wanted to try fixing that with a slightly different method but needed an unlit version of the terrain and a normals texture. Normals texture is fine to obtain with a custom feature, but for the unlit colour I wanted to use a renderer feature with override material. But, as @dull lintel just discovered, it doesn't carry over properties (mostly textures in my case) so doesn't work here.

While I think MaterialPropertyBlocks will work, they break batching with the SRP Batcher so if you're going to be rendering a lot of objects it'll be more expensive, unless you also support GPU Instancing.
An alternative is to have the shader include another Pass with a custom LightMode tag. The RenderObjects feature then has a Shader Tag IDs that you can use to render it instead of using an override material. It's then the same shader so properties still work... but adding a custom pass to a shadergraph isn't possible without editing the generated code. I ended up just hand coding a (simplified) terrain shader myself.
Still struggled to get the blending right though so kinda gave up for now.

[eager folio]

Very interesting...

[regal stag]

The macros basically get swapped out for other pieces of code. You could look at the CGIncludes source code to see how they are defined, https://github.com/TwoTailsGames/Unity-Built-in-Shaders/blob/master/CGIncludes/AutoLight.cginc (those two are at the bottom)

[eager folio]

My game is hopefully going to be somewhat stylized so I can accept a lot of simplification.

I wonder if you could use an SDF of the terrain for the blending

[regal stag]

No, if you want more control you should use your own global float shader property.
(Setup a Vector1/Float property in blackboard that's not exposed. Change it's reference to something like _CustomTime. From C# can then set it using Shader.SetGlobalFloat(_CustomTime, value);)

[regal stag]

How would you obtain an SDF? That's kinda similar to what capturing the depth achieves.

[eager folio]

Yeah, probably using a similar process

[low lichen]

Does Unity terrain not generate a heightmap texture?

[regal stag]

Could try a Subtract (or Add) node on the Position node with a value of (0.5, 0, 0.5)

[low lichen]

https://docs.unity3d.com/ScriptReference/TerrainData-heightmapTexture.html

[regal stag]

Oh that's cool, didn't realise it allowed you to do that

[green nebula]

ok thanks

[eager folio]

Yeah, that seems like it could be useful

[regal stag]

The "inverted hull" technique is usually the easiest, using a shader like this : https://github.com/Unity-Technologies/UniversalRenderingExamples/blob/master/Assets/_CompletedDemos/ToonOutlinePostprocessCompleted/Shaders/ToonBasicOutline.shader
Then use the RenderObjects feature with it as an override material to render it (filtered to a specific unity layer, would allow you to swap the layer the object is on to toggle the outline). Or just use it as a second material on the MeshRenderer.

Could also look into this : https://alexanderameye.github.io/outlineshader.html. Is usually used for fullscreen image effects but can also work on objects (see per-object part at the bottom)

[regal stag]

Are you using the texture's based on the sprite? It looks like the emissionTex for that sprite sheet isn't set up. You should also make sure the texture property is set to "Black" mode rather than "white", so the glow turns off rather than making the entire sprite glow when there is no emissionTex available.

[grand jolt]

oh yeah, I set it up now. certainly gets rid of the constant glow, but still how would I get it to change the emission map between animations?

[regal stag]

I think you should look into using the secondary textures on the sprite to add the emission map to each : https://docs.unity3d.com/Manual/SpriteEditor-SecondaryTextures.html

[grand jolt]

I did that for the idle sprite to get the emission map working

don't I have to do something inside the shader graph to get it working? since its only been linked to the idle

[regal stag]

If it's only been linked to the idle sprite then that's why it only appears during the idle animation. You'd need an emission tex for each sprite.

[grand jolt]

dont I somehow need to link the other sprites to the shader graph too?

[regal stag]

Or I suppose you could try obtaining the cyan coloured pixels from the regular sprite as a mask for the glow instead of a separate texture. There's a Color Mask node.

[regal stag]

Oh, your main sprite texture should be using the _MainTex reference to obtain the sprite from the SpriteRenderer. Same goes for the emission map, it should be the same reference for all sprites. e.g. _EmissionTex. That way when the sprite is swapped out, it obtains the correct textures too.

[grand jolt]

alright

I'll try to make it work with that

ohh

so I just name the secondary texture emmision maps as _EmmisionTex and unity works out the rest

[regal stag]

Should do yeah

[grand jolt]

seems to work

thanks again

[vocal thistle]

is there any way i would be able to have an HDR that has several colours that would spread out over what the material is attached to?

[grand jolt]

alright big thanks for the help

[deft mango]

does anyone know a way to apply an image effect shader to a Canvas with Render mode set to 'Screen space - Overlay'?

[pale ravine]

Hi, is there any way to debug fragment shader?

i get this effect when I work with algorithm I've got on alpha

I've translated it from Cg to HLSL and that's what I got

[vocal narwhal]

you can only return the values as colour to debug them

just remember that sometimes values may be beyond 0->1 so saturating them may be appropriate

[pale ravine]

Thath might be enough to figure out what is happening

[vocal narwhal]

as you may expect something to be 0, but it's actually gone into the negatives, which has affected future maths

[pale ravine]

brooooo, saturate helps a lot!

that was the issue, my alpha was way over 0 or 1

thank you so much!

[vocal narwhal]

Glad it was that easy 🙂

[pale ravine]

is it still worth to learn writing shaders when there's a ShaderGraph?

[vocal thistle]

yes

definitely

there is stuff you can code shaders to do that i don't think you can do in the shader graph

[grand jolt]

Would it be possible to create one myself? Or was your answer a hard no?

[amber saffron]

Well, the HDRP decal material has a normal mask input

[keen patio]

a problem about PCF shadow, if I increase the filter kernel, to a big number, is it possible to make soft shadow ?

like DF shadow

maybe can, but not as good as DF shadow, because shadowmap information is not enough.

[humble inlet]

ello folks! i have a bit of a query here!

if i texture for example, a perlin map, onto a plane, when viewed from an angle, the segment being viewed is stretched and scaled to the camera, as you'd expect. (black = plane, red = texture [arrow = scale direction, blue = camera viewport)

this produces what you'd expect from a camera, and simulates real-life. however, if i wanted the texture on the plane to not scale and stretch, so, for example, just map the perlin map from the camera, and stretch it to fit onto the plane, wherever you looked, the texture would look the same.

how would i go about doing that, if possible, in the shadergraph?

or would it have to be via a code shader?

[humble inlet]

tag me if you know how please! :D

[low lichen]

Sounds like you want to use screenspace UVs

Which is just using the screen position as the UV

[humble inlet]

right, so, i just plug that into the sampler? it's as easy as? i feel silly now!

eyup, that doesnt work... and, as im using a gradient noise node, i cant sample it, afaik!

Hello everyone, I'm having trouble changing a shader's color I'm doing it this way:

And this is the shaders properties:

But the color isn't changing

What am I doing wrong?

Thank you!

[low lichen]

Are you using the _LineColor variable in the shader somewhere?

All you've shown is you've defined a property in the shader, and set it in a script, but you haven't shown how you're using that property.

[silk sky]

Can somebody help me figuring out how build this shader in unity? https://www.youtube.com/watch?v=8_xCX9mGM5c

I have no experience with coded shaders, always used the graph.

[raw pollen]

Mmm I don't think so, how do I set the color in the shader ?

Sorry I'm really new to shaders and it's a bit overwhelming

[low lichen]

You should use the color property to somehow affect the color that is returned by the shader before it returns it.

But I assume it's going to be more complicated than just coloring all the pixels, since you have 4 different color properties.

Did you manually add this _LineColor property into a shader you didn't write?

[raw pollen]

Oh it's changing now, I just added a Coroutine and waited until the end of the frame

I'm guessing the color was assigned before the default color or something

Not sure if its the best way to do it

but... I guess it works for now

Thank you anyways @low lichen !

[silk sky]

any help? I havent understood if I had to split the code, trying to just put that shader into a material is not working

[wind sigil]

Can someone explain basic compute shaders? Specifically the line "void CSMain(uint3 id: SV_DispatchThreadID)" in te default shader. Is "id" the index of the input StructuredBuffer? If so, is it possible to input, say, 5 points to the shader and output 20? Would I need two StructuredBuffers? How would the compute shader know which to use?

[thick fulcrum]

are you looking to texture a plain or project a texture onto a plain (two different things)?

[low lichen]

Compute shaders are only helpful for parallel tasks. The shader function is executed multiple times at the same time. The ID tells you which thread is running. If you wanted to modify something like a texture, you can use the XY values of the ID to modify pixel at XY.

Inputting 5 points and outputting 20 points only really makes sense if each thread was given 1 point and then outputted 4 points. Accumulatively, they would output 20.

When you're working with just a buffer, you can ignore the YZ dimensions of the ID and just use the X as the index into the buffer.

[wind sigil]

Thanks for your reply. Are threads executed in the same order every time? For example, if I were to say (pseudocode) color[id.xy + terribleblurRadius] = color[id.xy], same order is required else the texture would flicker

[low lichen]

There's no order. They are executed at the same time. That's what parallel means.

[wind sigil]

oooooh, so it only relies on the input. mind blown. parallel so strong

[low lichen]

You need to be careful with read and writing to the same resource. It's fine if each thread only writes to its own set of pixels/indices.

For something like blurring, you'd want to have one texture as the input and another texture to write to.

[wind sigil]

i see, so that might be why my river is flickering 😦

[spice iron]

this is probably a silly mistake, but I can't seem to figure it out. I have a new empty PBR graph in urp (right image) with just a color plugged in to the albedo, to the left is just the default shader. as you can see the default shader also picks up all environment lighting, and I can't seem to figure out how to do the same in shader graph.

[low lichen]

@wind sigil For iterative processing (which your simulation appears to be) you can use a double-buffered approach. You have two textures, one to read from and one to write to. After you've dispatched the shader once, you swap the textures. Now you read from the texture you just wrote to and write to the other.

[wind sigil]

oh, not iterative. should be not moving ever. I only have one buffer in the compute shader. Specifically what do you mean by reading and writing a texture?

[low lichen]

If it shouldn't move ever, why do you need to continually dispatch the compute shader?

[wind sigil]

oh, it's done every few seconds b/c infinite world

[low lichen]

Seems like a waste. Nothing around it has changed, so it doesn't need to be recalculated.

[wind sigil]

i mean, since it's an infinite world, once the player moves to another chunk, the mesh for the river needs to be updated to fit the river formations in the new chunk

anyways, when you say reading/writing a texture, are you referring to cb.SetData and cb.GetData? b/c i'm reading and writing to different arrays (vertices1 and 2) but still flickering 😦

[low lichen]

Does the compute shader read and write to just one index of the array?

[wind sigil]

yup, 1D arrays

[low lichen]

In your screenshot, I'm only seeing one buffer being given to the compute shader

Is it reading and writing to that one buffer?

[wind sigil]

yup. oooh do you mean two RWStructuredBuffer inside the compute shader?

[low lichen]

Yes

Well, one StructedBuffer (for reading only) and one RWStructuredBuffer (for writing only)

[wind sigil]

oooooh i see, lemme try that. That makes so much sense now

[low lichen]

It's fine to read and write to the same buffer, but only if different threads aren't trying to read and/or write to the same indices

[wind sigil]

i see.... on a possibly related note, how do yu determine threadGroupsX in computeShader.Dispatch? I'm using vertices1.Length/8 but any lower and it seems to skip points on the mesh. any higher and Unity yells at me for pushing thread limits or smth

[low lichen]

It depends on the numthreads you have on the kernel

If you're just using the X dimension, then it should be something like 64,1,1

You can try different powers of 2 to see what works best for your hardware

And divide the length of the buffer with the number of threads

So if you use numthreads(64, 1, 1), then you should dispatch as vertices.Length / 64, 1, 1

[wind sigil]

coincidentally, im using 8,8,1 numthreads. makes sense

thank you for all your help. you probably saved me days of trial-error/googling lol

[humble inlet]

project on to, i guess

[lean lotus]

is there any way to see what parts of code in a compute shader take the most time? desperately trying to optimize/debug one but i have no clue what tools can be used, nor how to use the one i tried(renderdoc)

[shadow locust]

There's the Frame Debugger

but

I don't think that will tell you much about the inner workings of your shader

I think RenderDoc is the best bet

and yeah I'm afraid of RenderDoc

[lean lotus]

yeah, opened up renderdoc yesterday, and dear god
is there anything that can show me the times parts of a compute shader take? really strugglin with debugging and optimizing the compute shader when idk what is taking up the time and why(and I dont know how to make sense of what stuff in renderdoc means)

[shadow locust]

One thing to try - start removing/commenting parts out

see how the performance is affected

[spring frost]

Questions about Mipmaps:

• can I make my own (as in, specify an image to use for each mip level?)
• actually I'd just need to know whether a certain mip level is reached for a fragment.

But some manually built images would be great too (because filtering doesn't cut it for a type of distance field I use for dithering, and there are reasons :D).

[lean lotus]

but its big parts, and many parts that if I comment them out, it just straight up doesnt work
theres the obvious things(like have less things to intersect(ray tracing compute shader thats related to the 2 scripts from earlier)), but knowing the general problem doesnt tell me what changes I make help or hurt, nor lead me to a potential solution
Ugh why cant there be a simple way to see how long parts of GPU code take compared to other parts...

[shadow locust]

I mean don't worry about it working or not

it will break obviusly

but if you remove a part of the code and suddenly your performance is improved 5x

you know the removed part is bad

or at least - that removed part has a performance issue

[lean lotus]

but the parts that do that would be the ray-BVH intersection algorithm, but idk what to do to optimize it cuz idk what changes improve it or make it worse

[spring frost]

This is not how I build my own world space fragment normal in an
unlit shadergraph ... right?

[shadow locust]

make a change - run it

if it runs slower, it is worse

if it is faster, it is better

[humble inlet]

can you use system diagnostics in a shader?

[regal stag]

After the Normalize, use a Transform node from Tangent to World instead

[spring frost]

Thank you, @regal stag

Yeahhh thats way better, now grooves are always grooves 😄 I guess then I also don't need to blend with the mesh normal because the tangent space transform will take care of that.

[dusty pivot]

is it possible for a sprite shader to extend out of the original texture size?
im currently moving the uv up and down so that the texture bobs, but it gets cut off at the texture borders

one fix is adding transparent margin to the texture, but id preferably not have to edit the textures

[eager folio]

@dusty pivot Scale the sprite mesh up and scale the texture down in the shader?

[spring field]

Thank you!!

[thick fulcrum]

What you probably need is a Decal or that sort of technique. If I recall you were / are on URP, while there is no built in support there is a good example on github which I've used myself in a few different situations. You need to use it on an unlit graph, but it's entirely possible to give it lighting support https://github.com/Harry-Heath/URP-Decal-Node
It does need a few tweaks imo to clip properly, but it's a good starting point. Alternatively a fully working unlit decal shader that's pretty robust is https://github.com/ColinLeung-NiloCat/UnityURPUnlitScreenSpaceDecalShader
Side note there is URP Decals on the unity roadmap, so if these don't fit the bill you can always wait for them.

[humble inlet]

thank you very much, my friend!

I believe you have misunderstood my question, however

[thick fulcrum]

Then perhaps you need to elaborate or re-word the question as it is not clear as to what you want or are trying to achieve 😉

[humble inlet]

apologies!

I wish to texture a plane with a Perlin map, but, instead of the texture being stretched onto the plane, instead, I want the texture to be 'masked' onto the plane, so the orientation and stretching is always the same, as it is correct to the camera

[humble inlet]

I refer you to my diagrams, here:

[trim ermine]

I have an impossible task

I want to take megascans and convert them to backgrounds that would work with anime characetrs.

Anime backgrounds are often detailed realism but painting.

Anyone know any good shader tricks I could use?

[thick fulcrum]

okay I will approach this in a different way:

1. you can try mapping the plane using "world space" UV's this will avoid stretching but can introduce repetition.
2. if you always want it orientated to camera (this will look odd imo) probably achievable by using screen coords as the UV input.

[humble inlet]

repetition is fine

I am using a Perlin map, so a 2d array of floats. how would I use screen space UVs for this? I understand that I need them, Im just not sure how to do it

[thick fulcrum]

is this in code or shader graph?

[stray frigate]

Hey. Did someone know how to deal with 3d lighting on World Space Canvas, but in URP? I found that without URP, setting up UI material shader to 'Sprites/Diffuse' deals with it, but it isn't convertable to URP shader. I was trying to write my own shader for that, based on tutorial on Unity blog 'Custom Lighting in Shader Graph', but with no luck (I am shader noob). It kinda works for main directional light, but not any additional lights. Maybe someone has written that kind of shader and it is available to buy in asset store?

[civic holly]

i want to render a grid based game (e.g. chess) entirely using a custom image shader that will fill the whole screen. i've got the shader in position, but i need a way to pass the current board state (an array of integers or floats) into the shader properties to be accessed. how can this be achieved? i've successfully sent single floats to the shader, such as mouse position coordinates, but can't find an answer as to how to do it with an array. hopefully someone here is familiar with this problem and how to solve?

[civic holly]

https://docs.unity3d.com/ScriptReference/Material.SetFloatArray.html this should work right? i'll have another go at understanding this tonight.

[grand jolt]

has anyone used quick outline shader ? I have some issues with that see I am able to view it even when there are objects inbetween how to solve it

[eager folio]

Just scale your quad up in proportion to how much to scale down the UVs and you'll have a larger empty space around the edges.

[dusty pivot]

but i want the pixels per unit to remain the same

[eager folio]

If you half the size of the uvs and double the size of the quad... it will look the same size.

[cedar turret]

If I'm going to define a 3D boolean field in a compute shader, what data type should I use?

essentially I want a 3D grid of points that are either enabled or disabled

I was thinking something like a Texture3D, but there is no texture format for exclusively 1-bit values

I don't see the point in using an 8 bit texture format when I'm only ever using 1 bit

[dusty pivot]

can i change the quad size through the shader? or do i need to modify the scale property of the game object?

[eager folio]

@dusty pivot I could do it in the shader by adjusting the vertex positions, but just scaling it in the inspector is much easier and saves a few nodes.

[dusty pivot]

oh I see

thank you!

[dusty pivot]

do you know what the relation is between the tiling and the offset so that the texture stays in the middle?

oh i figured it out 😄

literally been trying things out for 20 minutes and the moment i decided to ask i figure it out xD

[noble pagoda]

Is an attitude of cache friendliness helpful in shader programming?
I just learned that in multi-core CPUs, each core has its own L1 (and often L2) cache, so I'm wondering if GPUs have groups of caches (whether for individual cores, individual stream processors, or whatever) and, if so, whether I should be worrying about cache misses when trying to make complicated compute shaders.

Like say I'm pulling values out of a structured buffer in each kernel instance; if my shader is slow, is it likely to be because I'm jumping around in the buffer or between buffers?

[cedar turret]

my shader crashes my computer every time I run it, is there any good way to sandbox it so that I can debug it without it breaking my gpu in the process?

[teal breach]

Is there any way to get the depth buffer values from a Render Texture? I'm trying to make a nice real-time reflection for an isometric game by rendering to a second camera. I'm creating a rippling water surface and using that to adjust the UVs of the samples scene color to make the reflections undulate. It looks like, but I'd like to weight the amount of UV coordinate change using the depth of the reflection camera compared to the scene camera - then, when an object intersects the water I can turn the effect off to make the object meet up with it's reflection

[leaden radish]

anyone made a pixel shader for 3D models here?

to make the 3D model look like pixel art?

[eager folio]

@leaden radish The pixel perfect camera?

Or even just render to a low resolution render texture?

[leaden radish]

found it

nah not pixel perfect caemra

m turning my 3D models into 2D sprites

researched on it and found solution about it

dead cells approach

who wanna draw so many darn frames anyways xD

they are not even modular

now i can make that fighting game again

and don't have to make so many frames

[civic holly]

has anyone here ever sent an array of floats to a shader? i'm unable to move forward because i don't understand how. it's surely a common task for shader writers?

i've created a 2 dimensional array in c#, and am trying to send it to the shader

i get this error: Assets\Inputs.cs(40,38): error CS1503: Argument 2: cannot convert from 'float' to 'System.Collections.Generic.List<float>'

// initial declaration
public float[,] arrayIndices;
// then in start function
arrayIndices = new float[arrayWidth,arrayHeight];
mat.SetFloatArray("_Indices", arrayIndices);

[eager folio]

I believe you have to use float2 rather than float

[thick fulcrum]

I believe it's more efficient to send a single dimension array, you can easily convert too and from multi dimensional to single dim with a little maths.

[civic holly]

i was thinking that doing that maths inside every fragment shader would reduce efficiency, but i will try that.
regarding the float2 idea, i thought that was like a vector2, so i don't think that can be right.

[teal breach]

are you rendering the object to a render target, and using the direction of normals to camera for coloring?

[civic holly]

so i'm not getting an error now, but also the one dimensional float array in the shader has all its values stuck at 0, while the float array in c# script has them set to 1, 2, 3, 4, 5... (which is what i want them to be in the shader, for this test)

[dusty pivot]

I have this simple shader that's supposed to enlarge the sprite and it works fine if there's only one object with the shader on the screen, but as long as there's multiple some objects get weird offsets. Does anybody understand what's going on?

[dusty pivot]

does someone know how i can add these tags (https://docs.unity3d.com/Manual/SL-SubShaderTags.html) to a shader via shadergraph?

I figured out that the my previous issue is due to batching, so i want to disable it for the shader

[teal breach]

How do I get the distance of a fragment to camera in shadergraph? I thought it was just ScreenPosition (raw).A, but I'm just getting a flat color in an orthographic projection

managed to find it: https://www.cyanilux.com/tutorials/depth/#eye-depth

[dusty pivot]

can i use the Color property in the SpriteRenderer component in a shader, without it changing the color of the texture?

[teal breach]

I was able to get this working, but I had to write a SRP render feature to blit the second camera's depth into another render target, so I could then sample that from shader graph

The purpose was to make this reflection effect, so that the amount of reflection distortion depends on the distance between the water fragment depth and the reflected texture depth. It kind of works - the base of the legs don't wobble much in the water, whereas the top of the body does

a clearer image showing the difference in depth between reflection RT and water surface

[civic holly]

can you help me set a single dimensional array in the shader? sorry to trouble you but it sounded like you knew how, and i can't get it working and this has been a roadblock for a week now for me.

[spring niche]

Hello I would like to change the color of my door with the little color picker but I would also like to have a sort of mask that can prevent the windows from changing color, is there a way to do it or I have to create multiple materials in photoshop ?

[thick fulcrum]

sry I was assuming you meant compute shader when mentioned array, I'm not sure about sending it to a material shader if there's anything to be mindful of.
Have you tried setting / altering a simple value like a float or int to check that you are communicating with the correct and expected material. You need to be careful of shared materials and instancing etc with Unity.
Alternatively if your array is within color ranges you can probably write it to a texture and pass that, although it's probably not the most efficient method.

[civic holly]

yes, changing a single float seems to work fine. it's just the float array that doesn't seem to work. i wish i had a simple example of what to write in the shader and where.

[thick fulcrum]

in your shader is the array setup in a material property block as per this thread?
https://forum.unity.com/threads/passing-array-to-shader.392586/

also the size of the array cannot grow, so if it's set too small initially I believe the data gets discarded.

[severe sluice]

Hello! I'm quite new to shaders and I'm trying to use a StructuredBuffer (of heightmap data written by compute shaders) to displace and colour vertices of a mesh. Using surface shaders as I didn't want to delve deep into lighting currently, and I got the displacement working but it always ends up being all single colour. I'm not sure where the problem lies. It seems to take a value from a single location in the buffer. I'll look how I can post code of the shader in question.

[severe sluice]

I'll put the code as a screen capture atm. The issue is changing the albedo in surf(). Not sure if adding texcoord etc. to the Input struct is entirely unnecessary or just plain out wrong (still learning) but, trying out different options and scaling, the end result is still the same

[severe sluice]

to give an idea of results: current (left) and with a modified unlit shader I used previously (right).

colour is applied in the same way as before, and it does visibly change after every replay

[civic holly]

just wanted to let you know it's working now. thanks for your help. i think the issue was that i created the array only in the start function. schoolboy error.

[dusty pivot]

I tried doing it in shader graph, but without any success. Do you have an idea how to do this?

[eager folio]

@teal breach no. Just using view direction to the quad.

[earnest knot]

can i create shadergraph shader in 2D project?

[dusty pivot]

yes you can, if you have the right 2d packages you can go to create -> shader -> universal render pipeline -> sprite (un)lit shader graph

[quiet silo]

Im using the camera viewdirection in my shader but it doesnt seem to work on imported models does anyone know why? I have this in my fracment function

float3 viewDir = UNITY_MATRIX_IT_MV[2].xyz;

it does work on unitys standard 3d objects

[earnest knot]

What is "2d pąck"

[dusty pivot]

go into the package manager and add all packages with 2d in the name

with save you a lot of hassle

[earnest knot]

Ok

Wait

[lucid sluice]

How can I fix the z-fighting here for these two intersecting semi-transparent objects without moving the objects themselves? I'm looking to modify the shader itself

[junior wagon]

how do I fix my code, it isn't doing vertex displacement

I only have one subshader

[regal stag]

You should be doing the vertex displacement before o.position = UnityObjectToClipPos(i.vertex);. The idea is that you are altering the parameter sent into that function.

[junior wagon]

huh

yeah, that's a thought

I'm just curious as to why it doesn't work because i'm rusty AF. I built the code about 6 mo. ago, then I tried to change it to use worldspace uvs instead so I could tile it, but then I dropped the project so I have something that somewhat works and i'm trying to revert it to how it was before

[fallen sparrow]

can anyone think of a reason why I get this error when trying to add a property to a shader?

Shader error in 'HealthbarShader': Parse error: syntax error, unexpected $undefined, expecting '(' at line 6```
Line 6 is the one that starts with _Health:

Properties
{
[NoScaleOffset] _MainTex ("Texture", 2D) = "white" {}
_Health ("Health", Range(0,1)) = .5f;
}

and I do have a `float _Health` lower down in the code as well.

[regal stag]

Maybe try 0.5 instead of .5f. Don't think you need f in shaders, and unsure if just .5 would work or not.

[fallen sparrow]

same error, I start off with it = 1; I was trying to follow along with this video https://www.youtube.com/watch?v=mL8U8tIiRRg but as soon as I add a property it fails to compile

and visual studio doesn't seem to have shader syntax highlighting/intelliSense

actually, I lied, the error did change, now it says

@earnest knot As long as you are using URP or HDRP you can use shadergraph

@quiet silo The mesh needs to have tangents and normals. If the mesh doesn't have them you need to add them in the importer(select calculate instead of import)

[hoary tiger]

Hey, I've been having issues with z sorting on a billboard shader that i want to use for 2.5 d. I'm not very experienced in shader coding (it would be less of a pain for both me and you if you'd do it). It's using the URP on unity 2018.4.20f1 (it's for Vrchat). I'd be willing to send some money if someone can figure it out.

here's the assets i'm trying to get to work

[vernal glen]

Any shader pros know which I would need to edit in order to stop my painted terrain grass from changing colors? It's happening even with all wind settings turned off:

I tried editing the WavingGrass but with wind off, I'm lost. I tried a bunch of other terrain tweaks too, but I think it's something with shaders. Upon getting near the grass, it changes colors significantly, up and even through to the point when I'm walking through the grass.

[shadow kraken]

Instead of moving the objects manually you could give one of the objects a small displace in its normal direction, to inflate it a bit

[restive radish]

Copy TerrainEngine.cginc into your shader folder, then comment the entire function WavingGrassBillboardVert, except the first line.

then, right click your shader and click to reimport

Does anyone know how to make my grass (shader) copy the color of terrain material? I want to make it blend in with the ground.

I think Cyan or Remy explained how to do this in URP not so long ago, but as a rough guide you can look at this example towards the bottom of the article is where he goes over the problem and how to minimize it. It's effectively masking the area above the surface.

Hi, what would the reason for mesh losing texture when it's exported to fbx from blender and imported into unity's scene?
Transparency is gone on some meshes too 😦

I created a shader in hlsl for raymarching that i applied to a mesh

for every pixel the objects takes up on the screen i march a ray

all of that works fine but i want to be able to render the normal unity scene

if the ray didnt hit an object or if another normal object

is in front of it

this is what i have so far

            half4 Fragment(Varyings IN) : SV_Target
            {
                float3 rayOrigin = IN.rayOrigin;
                float3 rayDirection = normalize(IN.hitPosition - rayOrigin);

                float4 sceneInfo = RayMarch(rayOrigin, rayDirection);

                float rawDepth = SampleSceneDepth(IN.screenPosition.xy / IN.screenPosition.w);
                float linearDepth = LinearEyeDepth(rawDepth, _ZBufferParams);

                if (sceneInfo.w >= _RenderDistance)
                    discard;

                return half4(sceneInfo.xyz, 1);
            }

how would i implement depth to this

[topaz hemlock]

What are some benefits of learning shader programming in Unity? Right now I am interested in it cause it seems cool and way easier to experiment with shaders compared to writing a opengl/direct3d program from scratch.

[tired bronze]

@topaz hemlock Large audience, helpers for keeping things crossplatform, ready to be used in projects or sold/given away on the asset store/github.

[topaz hemlock]

I am also curious which API uses CG? Like DirectX uses HLSL, OpenGL uses GLSL etc.

[amber saffron]

If I'm not wrong, actually none of these. CG is a higher level language that is ised to be cross compiled to the different target APIs

[topaz hemlock]

Ok that makes sense!

Unity uses a mix of Cg/HLSL right?

[amber saffron]

It is slowly replaced in favor of HLSL in unity (all SRPs code is in hlsl), that is still cross compiled afterwards.

[amber saffron]

Yes, both are supported.

What's the URP / HybridV2 shader reference name of the Color (pink in this image) property from the SpriteRenderer? It doesn't arrive in my Sprite Unlit shadergraph (I presumed "_Color")

Duh. I had set the shadergraph to Unlit in my search for the issue, backing me into a dead end.

[heavy pebble]

So I was using a derivation of this (Painting in UV space) https://www.youtube.com/watch?v=YUWfHX_ZNCw to paint a trail of the player on the ground material, but I've run into multiple issues due to the lack of layers on resets. I looked into lightmap painting and that as well to my research does not support layers.

Full context : I want to use surface paining to achieve two things,

1. The player can see on the ground where he's been
2. Visual Hints on where the player should walk on demand.
   So this is why I need layers. If a player resets the current path he's already walked, I would still like to show the hint (if any) that was already painted and only reset the player trail.
   One possible solution I've considered is not using painting for the hints and using HDRP decal projector, atleast for the hints, but its potentially a thousand projectors. And as for resetting the player trail, storing the render texture when required to reset back to.

Are there any other options I can consider apart from the one I mentioned?

It will be an option under the Node Settings tab in the Graph Inspector window. I think it is only available in v10.3+ if I remember correctly? (Or maybe it was v11?)

[dusty pivot]

is it possible to set a default?

its annoying to have to change each one of them

[regal stag]

It's default is to inherit the previous one, so if you set the one down the chain they should all change

and what's the parent?

of all

oh i fixed it

it was because one of the subgraphs was using a 3d preview as main preview

[eager folio]

@vast saddle you can render the object opaque to a render texture and then place the render texture on an unlit, transparent object

still playing around with water, wanted to see if I could add an automatic ripple around stuff - I did a depth render from below and used a JFA to make a distance field which is queried to produce ripples. It looks trash right now but I'll tweak further

So I'm still having a problem with refraction. Notice how it "breaks" because of the depth check. Any smart ways of dealing with this ?

[mint storm]

Hi, I'm new to Unity and new to this Channel as well. I would like to ask what is the best way to go about fading an object? I do know that you cannot make an object transparent if the Material is to set to "Opaque", you can only make it transparent it the Material is set to "Transparent".
But here comes the problem, when I set the Material to "Transparent", even at Max Alpha Value of 255, I can see through the objects at certain angles.

Angle 1

I can already see though some edges of the cube

Angle 2
I can see even more stuff, which is the handle in my case

I'm also using Universal Render Pipeline for your info.

I'm guessing the solution will probably be related to Shaders? Which I totally have no clue in how to write Shader or even the Shader Graph. The water Shader that I made in the screenshot was actually blindly following a tutorial.
Can anyone help me with this? I'm total new if the solution is related to Shaders. A detailed step by step on how to solve this problem would be nice. If the solution is not related to Shader, it would be nice to know too. I'm very desperate as I didn't know a simple function as fading could be so complicated in Unity.

also I'm using Unity 2020.3.2f1

Thanks in advance!

                //half3 lightCol = lerp(col.rgb * _LightColor0.rgb * _LightColor0.w * 4, col.rgb, saturate(gray*_LightColor0.w));
                //#endif

                return half4(col.rgb * _ColorStrength, col.a);
            }

Is it better to remove if and instead, always calculate the nested stuff or not?
Also, please do not consider #if preprocessor

The transparency you see would be because there is transparency in your colour map alpha channel @mint storm. This is then multiplied by the alpha value slider

It only seems to happen with the URP 2D Renderer?

Hi Ole, currently I do not have any colour map attached to it, I just use the default colour option inside the material to change to my desired colour. If I were to put a colour map with full alpha, does that mean i won't be seeing through the object anymore?

[mint storm]

@shadow kraken I've tried putting in a colour map (.jpg) but I can still see through my material at 255 opacity. A .jpg image doesnt contain any transparency right? But I'm still able to see through it at 255 opacity. What could be the problem?

[shadow kraken]

I'm not sure what I'm looking at in that screenshot

I thought you were referring to the water material earlier, that's why I asked about textures

So what do you want transparency and what does those meshes look like?

[mint storm]

Sorry maybe I didnt make it clear. I wasn't referring to the water material. I was referring to this.
