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

Any news about this issue ? All my builds failed because of that and I don't know how to to fix that. Kind of frustrating.

 

This is my log:

I totally commented on this back in November - still completely broken 100% of the time for android and iOS. Please respond, as this is completely unacceptable.

 

and now it's spread to our other project - so I officially can't deliver builds for either one of our products. This is just awful.

anyone home, Unity?

For the record:

[Unity] Shader compiler: internal error compiling shader snippet type=0 platform=5: Protocol error - failed to read correct magic number

[Unity] Shader error in 'Standard': Internal error communicating with the shader compiler process

[Unity] Player export failed. Reason: Shader error in 'Standard': Internal error communicating with the shader compiler process

! build of 'default-android' failed. compile failed

Finished: FAILURE

occurs consistently with any mobile builds on either of our products. this is now a production issue for us, as we can't generate QA builds, and thus can't test new changes and ship them.

I've opened a support issue, responded here, even tweeted, and you guys are asleep at the wheel. Please respond.

 

I too am getting the same error. Its not at all building for iOS now.

Shader compiler: internal error compiling shader snippet type=0 platform=5: Protocol error - failed to read correct magic number
156: [Unity] Shader error in 'Sprites/Default': Internal error communicating with the shader compiler process.

Unity version is 5.3.5f1.

 

I am also experiencing this problem. Similarly like someone already mentioned -> it started failing after I added particle system to my project.

 

same problem here, after changing from unity 5.5.1f to 5.6.1p4

(tested with two different projects)
​

nevermind. it was just a misguiding error in the log. above were other compileerrors.

edit 2: unfortunately after fixing the other errors (which were because of some facebooksdk namespace errors after upgrading unity to 5.6) I still got errors..

30929: [Unity] Shader compiler: internal error compiling shader snippet type=0 platform=5: Protocol error - failed to read correct magic number

30938: [Unity] Shader error in 'Sprites/Default': Internal error communicating with the shader compiler process


edit 3 (solution?)
So I got 4 project that had a 100% build fail rate after upgrading to Unity 5.6.1 on cloud build. Always with the Sprites/Default shader error. Thanks to the post of "fisher-lv" I tried to include this shader to the "always included shaders" list in graphics settings. Now everything works fine again.

 

Started a android cloud build and I'm facing the same error using 5.6.2f1:
Player export failed. Reason: Shader error in 'Hidden/Post FX/Grain Generator': Internal error communicating with the shader compiler process
Strange thing, this only happens on the android build and not with the Windows and Mac standalone builds.

 

Meh. Cloud build is broken. We used it in beta, and have tried to continue to use it. However, the support has been worse than terrible, and there seems to be no end in sight to this issue. We've moved to the wonderful unity plugin for Jenkins, and couldn't be happier. I suggest you do the same.

 

Just got this error again too.

 

Hmm, I'm subscribed to the Unity Plus service so I'm paying to use the cloud services. Will take it up with their support division as this isn't how it should be.

 

I don't know if this will help anyone, but for me, anytime I run into this issue, I change the config setting for the cache. If the cache is set to library, I set it to none, and if it's set to none, I set it to library and then restart the build.
Hope this helps.

 

we are getting constant errors with cloud build..

 

Getting this constantly now on this project (only with Android) https://developer.cloud.unity3d.com.../buildtargets/default-android/builds/379/log/

 

Have been in contact with their support division: Starting clean builds did resolve the issue for me. You can do this from your Cloud Build dashboard:

• Next to the 'Start New Builds' button is a drop down arrow.
• Select 'Build a combination of targets' from this list.
• Toggle the targets you wish to build for.
• Click 'Clean Build Selected' and your build will start.

Takes longer to build but al least it works.

 

Been getting several of these the last few days:

Shader compiler: internal error compiling shader snippet type=0 platform=5: Protocol error - failed to read correct magic number

 

Except when it fails, it goes to cooldown, even tho we got the plus

 

And once today, but succeeded on next build.

 

Broken here too, for cloud on Android & Ios builds. :-(

 

I guess that's the problem with Unity Shader Compiler process. I faced the same problem with Lux terrain Standard shader on Unity 2017.1.0f3. But before everything was fine.

UPD: BTW I wasn't even building - after I made some mods to the shader it errored out with this message in the console.

 

Error still occurs on Latest Unity Version. Anyone have a solution?
Also, are there still problem with GPGS? Tried to build with those and got library errors

 

Guys, we need a resolve for this. Critical that builds get done. Please update with relevant patch details.

 

I was having the same problem despite building a 2D mobile game that uses no materials. It turns out that a material in one of my installed packages was using Mobile/Particles/Additive, apparently instigating the above error. Since our project needs no materials, I deleted it and was able to build our iOS build in Cloud Build (Android was fine for whatever reason).

This isn't a solution to the problem, but if you're like us and experience this issue for seemingly no reason, you might try removing any deleting any materials you aren't using from your project, specifically those using the shader that's appearing in your error log.

 

OK, I found a possible solution - kill Unity Shader Compiler in Task Manager. Worked for me.

 

im getting this too in text mesh pro,, then I rebuild it again and works fine

in 'TextMeshPro/Sprite': Internal error communicating with the shader compiler process

 

I've had some unknown compile issues on cloud build recently, might not be related to this bug, but this explanation of it satisfies me. Thanks for the transparent feedback, it makes me more confident that you guys really know your stuff! (because I don't )

 

For me, I had this error with the Skybox shader in the cloud build for iOS. All I had to do was change my camera in the scene to depth only, not skybox, and the error went away.
Not the best fix for people who need skybox, but hey, its what fixed it.

 

I also ran into this error on two builds. It's complaining about:
[Unity] Shader compiler: internal error compiling shader snippet type=0 platform=5: Protocol error - failed to read correct magic number
276: [Unity] Shader error in 'Legacy Shaders/VertexLit': Internal error communicating with the shader compiler process

However, I don't know what would be using the shader, I can't easily find it in my project, and our 2D game doesn't need any materials other than for the sprites we're using. Any ideas?

 

so when was unity will gonna fix this? I'm in windows pc and im depending in unity cloud build for ios build.. it will took 3 to 4 hrs to make a build when error happens.. cause of the cooldown

 

Getting this error as well:

Code (CSharp):

1. 9197: [Unity] Shader compiler: internal error compiling shader snippet type=0 platform=5: Protocol error - failed to read correct magic number

and then:

Code (CSharp):

1. 9203: [Unity] Shader error in 'Sprites/Default': Internal error communicating with the shader compiler process

 

When is 2017.1.2 expected to release?

Thanks!

 

I get the following compilation Errors for shaders when compiling for OpenGLES30. Tried it with different Unity versions, with the newest 2017.2.0f1.

"Assertion failed: Shader Compiler Socket Exception: Terminating shader compiler process, 0 retries left"
and
"Assertion failed: Shader compiler: internal error compiling shader snippet type=0 platform=9: Protocol error - failed to read correct magic number"

I am not using Cloud Build. Could this be a hardware issue

 

Same on 2017.2.0f3

i have a shader build error and cant compile locally its for a work and i need it can you help me to build and fix this shader and build error please?

 

We get this too, on our in-house Team City build server, on Unity 2017.2.0p1. Shader is Nature/Terrain/Diffuse. Happened last time while building OSX 64 bit release standalone. Was building after a successful build for Win 64 bit development standalone.

It's not a blocker for us since it's very rare, but this kind of random failure is intensely annoying, and would be even more so if it happened while we were waiting on an important build.

Here's an excerpt from the log of the most recent failure:

Shader compiler: exception while compiling shader snippet. Thread=1160 Type=0 platform=15. Source:

This error occurred to us for the first time now.

Continuous integration and default target builds work fine on Unity Cloud.

Made a new target for branches (as a copy of Default) and it failed on the #1 build. Hopefully #2 works (no changes, only restart). Would be nice if this got solved for good. Inconsistency removes one advantage for CI and cloud builds.

 

I get this error about every 30 minutes.

2017.3.1, trying to change color grading from Neutral to Filmic:

Shader error in 'Hidden/Post FX/Lut Generator': failed to open source file: 'ACES.cginc' at line 10 (on d3d11)

The only solution I found is, change back to Neutral, turn off Color Grading, quit Unity, wait 10-15seconds (so Windows throws it out from memory), restart Unity, turn Color Grading back on but don't you dare to change "Neutral" to Filmic ever again (same issue).


[EDIT: Getting similar errors with Eye Adaptation as well. Same thing to do here, except, leave Eye Adapt. off, otherwise things go wild...]

 

https://i.imgur.com/upiH0DS.png
I'm having this a lot. instantiating tiles and doing Shader.Find to set the fog of war on each tile. Pretty sure it's because I'm instantiating lots of stuff and the shader.find just fails there...
Just so you know...

 

I was getting this error relentlessly, and I decided to build with development build checked, and it worked so I tested it after that unchecking development build and it works again, got this error deleting old assets from my project and this is the first thing that worked for me 2018.1.0f2

 

Just got this error today on Unity 5.6.6...

 

Seeing this error in 5.6.6f2. Frustrating.

 

lol thats old man you should update your unity XD

 

@Ryanc_unity getting this error on 2019.2.8f1 broken builds 100%
FORWARD, Vertex Program: Internal error, unrecognized message from the shader compiler process. Please report a bug including this shader and the editor log.

[Update]
Found the reason why it happened.
I uninstalled the following and the error is gone!
"com.unity.2d.tilemap": "1.0.0",
"com.unity.polybrush": "1.0.1",
"com.unity.postprocessing": "2.1.7",
"com.unity.probuilder": "4.0.5",
"com.unity.shadergraph": "6.9.1",
Looks like something is messy with one of those packages and shader compilation.

Anyone having this problem. Just remove all unused packages from Unity and then try again.

 

100% broken builds with Unity 2019.2.8.f1. These are desktop builds, not cloud builds.

I tried removing a few packages but no luck so far

 

I tried, it didn’t help me.
