Cloud build fails to compile standard shader for Android

Unity Services
1

I built my project with no problems on my laptop to my local android device. In the editor it runs fine as well!

But in the cloud build a standard shader does not compile (mobile/particles/alpha blended). This results in a particle effect only showing pink quads instead of a nice explosion of stars!

I use locally the editor version 5.3.4f1. On cloud build I use latest version 5.

This is the error I find in the log:
Shader compiler: internal error compiling shader snippet type=0 platform=5: Protocol error - failed to read correct magic number
2120: [Unity] UnityEditor.BuildPipeline:BuildPlayerInternalNoCheck(String[ ], String, BuildTarget, BuildOptions, Boolean, UInt32&)
2121: [Unity] UnityEditor.CloudBuild.Builder:Build()
2122: [Unity] Shader compiler: UnityShaderCompiler compiler executable disappeared on thread 2115105536, restarting
2123: [Unity] Launched and connected shader compiler UnityShaderCompiler after 0.180000 seconds
2124: [Unity] Shader error in ‘Mobile/Particles/Alpha Blended’: Internal error communicating with the shader compiler process
2125: [Unity] (Filename: Mobile-Particle-Alpha Line: -1)

Can anybody explain this for me? What should I change to make the cloud build successful? Any Unity staff around maybe?

Thanks a lot!! :slight_smile: :slight_smile:

So after I built through the cloud a second time, the error disappeared. Either it was a one-time thing. Or it was fixed. Or it happens only on certain machines.
