Problem With Shader Graph

When I want open shader graph it shows me an only gray editor. Any solution to fix it?

NullReferenceException: Object reference not set to an instance of an object

You're running this in a project that's using HDRP, LWRP, or some other SRP?

If so, the first things I'd do are just restart Unity, then if that doesn't work, uninstall ShaderGraph and reinstall it.

 

I am just playing with shaders nothing special, was following tutorial

so it is LWRP.

Yes, already tried uninstall ShaderGraph and restart Unity3D but no one didn't help

 

Which SRP-related packages do you have installed?

 

I have the same problem i try several version but same problem, any news ?

 

Same issue here.

* A fresh project with 2018.3.10f1.
* Install the shader graph 4.10.0 from package manager.
* Create a new unlit shader graph and the double click to open it.

Then a blank editor window shows up with the same error report as the top post.

 

I found the solution. I should create a SRP asset and set it to the graphic settings.

 

I was having the same problem with an older project updated to 2018.4. Thanks jayatubi, your solution worked for me, but I had to also update all materials in the project to LWRP. Instructions for both steps follow.

Hi, I had same issue and in my case was solution very trivial. After deleted content of the Library folder it works.

 

I had the same issue. Deleting the content of the library folder also worked for me. Thanks Cemada for pointing it out.

 

In my Case using LRP with Shader Graph: After installing Shader Graph, Lightweigh RP and Post Processing, R. Click on Assets -> Create-> Rendering -> LRP, then Edit -> Project Settings -> Graphics -> Locate LRP which you created in Assets. Since you cant use the old Shaders with the new ones or something.

 

Hey, guys im trying to make a game and i wanted to create shader and there is my question, should i update all my textures and graphics to that Lightweigh RP or should i stay with default one? Should i build my game on that new shaders?

For me to get that graph shader to work i had to add Render Pipeline asset in Project Settings and after that all my textures went pink ;s

 

same here

 

It's pretty much either-or: If you want to use Shader Graph, you'll need to be using a Scriptable pipeline, like URP or HDRP. However, doing so means that a fair number of things in the standard renderer will no longer work. Probably for most people, the decision to use URP/HDRP involves more than whether they want to use Shader Graph, so you'll need to decide whether that's what you want for your project as a whole.

 

I know this is an old thread but I'm having the same issue. I was able to create shaders through shader graph but now it will no longer let me. I get the same error when i try to open any of my shader graph shaders. I'm on 2020.2.1f1 using URP 10.2.2. @tehusterr, What library folder are you referring to?

 

Hi,I did it your way. But the version I'm using is 2020.3.12f1c1，This version is no longer available LWRP，so I am using the URP. But nothing changed,the problems remains. What am I supposed to do?
URP version:10.5.1
ShaderGraph version:10.5.1

 

Hi, I need help, for some reason my shaders have been behaving weirdly and my PBR and VFX shaders are gone, why is this happening and how can I fix it?

 

My Shadergraph is completely broken after upgrading to 2022.1.21f1. I have uninstalled URP and ShaderGraph. Now, I can not uninstall Shader graph. The Remove It is greyed out.

Any ideas?


I rolled back to the 2021 LTS and reimported. All is good now.

 

Started having this problem on 2022.2.2f1 with built in shaders on shadergraph for android.
error message is shown two times on playmode (Editor)

Code (CSharp):

1. NullReferenceException: Object reference not set to an instance of an object
2. UnityEditor.ShaderGraph.Drawing.MaterialGraphEditWindow.OnDisable () (at ./Library/PackageCache/com.unity.shadergraph@14.0.4/Editor/Drawing/MaterialGraphEditWindow.cs:417)

No error is shown on android, but sometimes it just freezes after some time.
I'm not having any kind of artifacts or visible broken shader. I've revisited and recompiled all shaders after updating.

Any ideas?

 

Unity stops showing the error after closing the shader editor tab.
The error is not fixed but at least the error won't show.

EDIT: The error was shown two times because I had two shader tabs opened
