Build error: "Shader compiler: internal error compiling shader snippet type=0 platform=5"

I found out something interesting about this issue. My teammate was able to build the same project project using the same Unity version as mine. No shader errors, no pink screens etc. So there must be something on my machine that's corrupting the build process. Unfortunately, clearing the library folder did not help.

Also, another thing. I used to get this error in Unity right after starting the build process. Now, the build in Unity goes ok, but the application crashes in XCode indicating problems with several shaders. Clearing the library might be what caused this change but I'm not sure. Every once in a while I get this in Unity, too.

And finally, this is happening for many of my projects, not just one. So this is definitely some global problem of Unity.

 

Unable to build anything in unity 2019.2.9f1. Even simplest project build fails for Android atleast with shader error.

Does the MacOS version of your teammate same with yours? I suspect that this error appeared after I upgraded to Catalina. 2018 Unity for example stopped building Android, it crashes on clang++

 

Same here, I believe this because of macOS Catalina too
In Unity Editor the shader import error so when we run project in XCode, error bellow:

Nope. I upgraded to Catalina and my friend is on Mojave.

 

I wonder, is Unity team working on this at all? Anyone submitted a bug report?

 

Try to change graphic API only to Metal

 

Could you please capture the screenshot where to change? Thank you!

 

I contacted Unity and they confirmed to be working on the issue.
The updates can be found here:
https://issuetracker.unity3d.com/product/unity/issues/guid/1185078

 

This does not work on Android too, not just iOS, I've posted this issue in a different topic earlier- https://forum.unity.com/threads/app-crashes-on-start-after-build-with-unity-2019-2-9f1.760634/

 

Yes I got fooled as well. After I did a clean build the error stop showing but now all my textures are Magenta instead.
The solution i tried did not work and is still not fixed by Unity.
All builds after Unity 2019.2.5f1 for iOS show magenta for every gameobject Regardless of shader from what i have seen.
I am now trying to "keep all" shader variants.


I will report with my results if it is successful.

 

Menu Edit>Project Settings then click on Player and uncheck Automatic graphic API, then on list remove OpenGLES (any version or all versions) and leave Metal ora, if it is not present, choose from dropdown

 

Hey, I had the same issue on a project and this worked for me, so thanks a lot !

 

@Marek_Bakalarczuk this didn't work for me.

 

It's funny someone in another forum said to remove Metal and keep the other but your tip is actually the one that worked. Removing metal basically made everything look and behave crazy in my iPhone build.

Anyway, thanks for the tip. Was stuck on this for hours!

 

I'm glad it helped.

 

So try in other way: remove Metal and leave OpenGLES. Just play with those settings.

 

I found a solution to this problem here: https://forum.unity.com/threads/unity-2019-2-7-build-ios-crashes-in-shader-compile.757754/

I reported my findings on this forum thread: https://forum.unity.com/threads/unk...-when-building-ios.758339/page-2#post-5170475

Also, 2019.3.0b10 works just fine.

 

In 2019 // 2020 betas there's also a issue (at least for me) where the "Standard Surface" Particle Shader never compiles fully and instead throws a internal error.

Whoever makes it to here:
Add the shaders your prefabs are using to that Always Include Shaders list in Project Settings --> Graphics. Rebuild your bundle assets and it should work.
