Couldn't load shader file 'ParticleSpriteVertexFactory' due to path error

rotwang · May 3, 2014, 5:55pm

When starting a simple game, following the steps of the “Pizza” example, I get this message:

/Users//dev/git/Unreal/4.1/UnrealEngine/Engine/Source/Runtime/ShaderCore/Private/ShaderCore.cpp(329): Fatal error:
Couldn’t load shader file ‘ParticleSpriteVertexFactory’

This seems to be related to the engine path error, I think, if we fix the path problem, these kind of problems will disappear.
OSX 10.9.2, UE 4.1

This still exists, currently in master branch on my Windows 10 machine, complaining about the new QuadOverdrawShader.

/Engine/Source/Runtime/ShaderCore/Private/ShaderCore.cpp(367): Fatal error: Couldn’t load shader file ‘QuadOverdrawShader’

When I start the editor itself first and load the project from there, it works though.

Hope this info helps tracking it down for a fix

Thank you

Hey -

Were you opening a new project in the master branch build or an existing branch? You mentioned it works if you start the editor first, what way did you start it that caused the issue? Do you have the same issue with the promoted/release branches or with the 4.10 branch?

Cheers
