Feedback Wanted: Shader Graph

Bumping this up in hope of some reply.

To illustrate the issue, here are two images where other cube is using HDRP Lit shader and other is using simplest possible shader made with Shader Graph.

When not using forward only from HDRP settings, both materials look identical:


but when setting forward only on, shader graph generated shader gets really light while HDRP Lit shader looks just the same as on non-forward only:

 

Hi!

I would like to create unlit shader color with black border.
Of course using graph nodes, not via coding.

Any ideas how to do it?

 

I would like to have a possibility to set stencil buffer settings via the shader graph :/

 

Hi Guys, I am using Unity 2018.2.0f2 the latest version on Mac and I dont have the shader graph, is it compatible with mac? or am I missing something?

thanks in advanced.
cheers

 

@testa3d, you have to install it (along with one of the scriptable render pipelines) via the package manager. You won't see in a plain new project.

 

I was gonna say.... It would be window -> Package manager... THEN you'll see our favorite feature so far.

 

@ssartell and @MythrilMan51 thank guys it worked perfectly.

cheers

 

it says the current render pipeline is not compatible with this node 'PBR Master' I have gone to edit - render pipeline and updated for a high definition materials and it still doesn't work. I will keep browner to see if I find the solution

 

Oh... YEAH.... THAT's annoying as hell.... Restart and try again.

 

Also... If we can convert our gradients into properties... That would be awesome.

 

Is there a summary anywhere of what is and isn't possible with Shader Graph at the moment?

I was considering using it to make a water shader, but wanted to know if it supports things like vertex displacement, reflection, refraction, etc.

 

Vertex displacement is in, kind of. I'd wait for a bit so it's a touch more stable and compatible, I think it doesn't play nice with some nodes?

Reflection is great in the HDRP in 2018.2, reflection probes can now be planar reflection probes, which gives you the nice water reflections that 'just work'.

Refraction could also do with some kind of probe, eventually, possible, not likely, but that isn't in yet. You can do it via script and another camera with a rendertexture and feed that in yourself.

 

Have anyone had success in making basic for and if nodes and if so then how?

Also is there anyway with this graph workflow to make "functions" or equivalent?

Thanks in regards

EDIT: I found compare which works for if, still not sure about for tho.

 

Sub Graphs = Functions and if you look through this thread a few pages back (around page 12 or so) @FreeGameDev made a lot of sub Graphs and posted a download link including "if" you can look through those to see if there's any other ones you would use.

 

Yo @wyatttt ! I'm keep poking Graphics.Blit + shader graph, and compare results with same code on unlit/texture from built-in shaders and... Unlit/texture still work, SG - still a "black nothing" =(
Do you have any progress with it?

 

What do you mean by this? Where we need to put it to be in pixel shader?

Is there a way to use this nodes (vertex displacement ones) for recalculating the normals?

Thanks

 

Thanks for the reply and help, Will read up on it right away!

 

Hey guys, any chance we get access to ddx_fine/ddy_fine functions?

I calculated normals from a greyscale input using ddx and ddy for a procedural shader and got a really blurry image as result.

I understand that the derivative calculation gives one value per 4 pixel square, and a solution I found online is to use ddx_fine and ddy_fine that calculate based on each pixel neighbors.
So far I've tried creating a custom node, but the result didn't improve, I think it's not passing the compiler check I setup.

Here's the code for the custom node:

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4. using UnityEditor.ShaderGraph;
5. using System.Reflection;
6.  
7. [Title("Math", "Advanced", "Ddx Fine")]
8. public class DdxFineNode : CodeFunctionNode
9. {
10.     public DdxFineNode()
11.     {
12.         name = "Ddx Fine";
13.     }
14.     static string DdxFine([Slot(0, Binding.None)] DynamicDimensionVector In, [Slot(1, Binding.None)] out DynamicDimensionVector Out)
15.     {
16.         return @"
17. {
18. #ifdef UNITY_COMPILER_HLSL
19.    Out = ddx_fine(In);
20. #else
21.    Out = ddx(In);
22. #endif
23. }
24. ";
25.     }
26.     protected override MethodInfo GetFunctionToConvert()
27.     {
28.         return GetType().GetMethod("DdxFine", BindingFlags.Static | BindingFlags.NonPublic);
29.     }
30. }
31.  

Here's the input of the node and the custom node I made (which since is not passing the compiler check, actually does the same as the existing DDX node). Notice how blurry the DDX node's preview is.


If there are no plans to include finer derivative nodes, what'd be a good way to do procedural normals with decent quality?

 

Hi!

1#
Remap node as property to achive this effect:


2#
Normal vector input to get noise from normalmaps.


3#
UV as property or uv offset and tiling as property so we dont have to use vector 4 to add offset and tiling.

4#
UV as property - list to chose which UV you want to use like in hd srp shader.

5#
Name in property should generate default name in shader code, manual changes are more then confusing


I build some cool stuff today. I will not push this into more advanced results until world normal function will not going to be able get inputs.

 

Please help!!! I updated HDRP , and my project broken

 

I love Shader Graph and Scriptable Render Pipeline. BUT, Shader Graph currently lacks the support for custom lighting models. It would be very very useful if Shader Graph could allow shaders with custom BRDFs. For example: I would like to change the fresnel approximation. For now this is impossible, as all shaders built in Shader Graph have to use the existing PBR equation.

Sci-fi displays))

 

Your gradient node doesn't serialize well. Shaders with gradients don't work on machines with "," as a decimal seperator.

 

Hey guys, couple ideas came to my mind:
1. Since we have position could we get object rotation also
(maybe transform matrix property and quaternions for some basic rotating action)
2. Motion vectors node for some fancy stuff
3. more human readable generated code (but that probably is the hardest thing I can imagine right now)

 

Also... I might be out in the dark on this... But how do I use custom data from our particle system in our Shader Graph?

 

Enable Custom data in particle renderer module (RENDERER!) and there are some preadded already like position, UVs etc. Next to each you can see what shader data are connected with it - e.g. UV on the photo is connected in TEXCOORD0.xy (UV node.xy) and Custom1.xy (Custom Data module) is connected with TEXCOORD0.yw (UV node.zw) etc.

 

And THIS would be the same if you're doing colors?

Hi every body,

I'm starting to try ShaderGraph but i get an issue... In ShaderGraph Editor, my shader display correctly :
But in the scene, it's the default gray shader... But it's the good shader in the material, and the good material in the object/sphere...

Have you any idea ?

EDIT : Ok i found the problem.. When i do CTRL+ S, that don't save the shader... I have to close te window to do it (after be promter to)...

 

... Yep... It does... Follow the top 3 for instructions.

 

There is "Save Asset" button on the Top Left corner of the window

 

Do Shader Graph shaders not work with the MeshInstanceRendererSystem? The material shows up if I select the HDRenderPipeline/Lit shader, but not a shader from Shader Graph (even the default one).

 

Did you check the "instancing enabled" checkbox?

 

On the material or the shader? It's enabled on the material. I don't see anything of the sort on the shader itself.

 

I also noticed that you can't use Sampler Texture 2D Output in Vertex Stage. I am trying to use ScreenPosition to sample a texture RGB value to change object position. Is there any solution to this? Also, the docs aren't updated and have broken wiki links. Having hard time finding stuffs.

 

I have a problem ,how to use depth blend in shader graph?

 

do you solve? i have the same problem

 

Hi Guys,

I'm starting to use the new shader graph as a replacement to Amplify, I'm wondering do you have access to Light Direction? currently I don't see anything to do this.

 

Hey, @wyatttt thank you very much for your detailed posts! I have a very specific question:

I dug deeper into the shader graph code and wondered what the precise difference between AbstractMaterialNodes and CodeFunctionNodes are?

I understand, that CodeFunctionNodes generate functions that are then reused within the shader. Even though I understand what the classes are doing, I don't 100% understand why exactly is it done the way you guys did. Can you explain that to me?

Thank you so much!

 

Hi guys,

I met a bug. I am not sure if it is a bug.

I tried to create a water effect using the Shader Graph.
First I would like to detect the distance between the surface of the water and the underwater ground (pic 1), so that I can make the water darker or lighter depending on the distance. To do that, I need to get the _CameraDepthTexture.

Pic 1​

I am suing Unity 2018.2.1f1, LWP, Unlit Graph. I did a test to obtain the _CameraDepthTexture and rendered it on a cube surface:
This is the scene, very simple, a cube a camera and a directional light:

Pic 2​

And Created a very simple Shader Graph to obtain the _CameraDepthTexture:
I added a property named "_CameraDepthTexture" which is the same as the "Reference", unchecked the "Exposed" box.

Pic 3​

I also set the LWP to support depth texture, and added the "Lightweight Additional Camera Data" script on the main camera.

On the scene view, every thing worked good. I could see the depth texture in the Shader Graph editor window, I could see the cube rendered with the depth texture on its surface:

Pic 4​

However when I clicked the "Play" button everything became dark. No camera depth texture rendered:

Pic 5​

I don't know why it became like this. Anybody met the same situation ? Maybe all the global properties such as "_CameraDepthTexture" are not supported yet. I did not see any documents on this.
