Rebuilding a 4.7 plugin in 4.10 I’m seeing this error:
1>C:\Program Files\Unreal Engine\4.10\Engine\Source\Editor\BlueprintGraph\Classes\K2Node.h(7): fatal error C1083: Cannot open include file: ‘K2Node.generated.h’: No such file or directory
The file exists at:
C:\Program Files\Unreal Engine\4.10\Engine\Intermediate\Build\Win64\UE4Editor\Inc\BlueprintGraph/K2Node.generated.h
But the compiler doesn’t see it.
Have you tried regenerating your project files?
“C:\Program Files\Unreal Engine\4.10\Engine\Source\Editor\BlueprintGraph\Classes\K2Node.h” is not the same location as “C:\Program Files\Unreal Engine\4.10\Engine\Intermediate\Build\Win64\UE4Editor\Inc\BlueprintGraph/K2Node.generated.h”.
Copy or move(This may cause errors.) the file from “C:\Program Files\Unreal Engine\4.10\Engine\Intermediate\Build\Win64\UE4Editor\Inc\BlueprintGraph/K2Node.h” to “C:\Program Files\Unreal Engine\4.10\Engine\Source\Editor\BlueprintGraph\Classes\K2Node.h”. The compiler is in a fixed directory regardless the file is near by. In “BlueprintGraph” folder there is a folder called “Classes”.
Instead of copying the generated file I set the path in …Build.cs:
PrivateIncludePaths.Add("C:/Program Files/Unreal Engine/4.10/Engine/Intermediate/Build/Win64/UE4Editor/Inc/BlueprintGraph");
This works, no more errors finding K2Node.generated.h. However, lots of errors in UE headers:

Now what?
:
I’ve also tried re-installing 4.10, verifying, regenerating the solution files, rebooting. Nothing helps.
It seems illogical that it’s necessary to add a custom path in order to find part of UE, that it must be a UE configuration/installation issue. I’ve exhausted everything I can think of to try with that.
Ideas?
Are you using a custom k2Node? Also please try to add comments not answers, if not it will be hard to follow the issue.
Any luck with this? I’m trying to inherit from UAnimGraphNode_Base, and AnimGraphNode_Base.generated.h can’t be found…
If your plugin compiles for target DevelopmentEditor but not for Development may be creating an additional editor module helps:
As a workaround you could also try guarding the editor specific code with the define WITH_EDITOR and UEBuildConfiguration.bBuildEditor in the build.cs like here:
Sorry for posting in such an old thread but I had a similar problem and wanted to share my solution.
I made my own custom K2Node which will work fine inside the editor. However when I tried launching the game or compiling for Development or Shipping I would get the “Cannot open K2Node.generated.h” error.
The solution was to add the required module to the PUBLIC dependency modules. For K2Nodes that would be BlueprintGraph.
I had compile errors while inheriting UAnimGraphNode_Base, and this solved my problem. Thanks!
