Development Getting Started & Setup

Hi unreal people,

I have a unreal 5.3 project that i want to compile from source and when i try to do that it gives me these errors:

E:\emp5\Plugins\PureWeb\Source\MappingPlugin\Public\MappingBlueprintLibrary.h(8): fatal error C1083: Cannot open include file: ‘Json/Public/Serialization/JsonReader.h’: No such file or directory

E:\emp5\Plugins\SocketIOClient-Unreal\Source\CoreUtility\Public\CULambdaRunnable.h(5): fatal error C1083: Cannot open include file: ‘Engine/Classes/Engine/LatentActionManager.h’: No such file or directory

every plugin that i put in the plugins folder is facing some missing stuff that visual studio is not able to find in the unreal engine.

i have tried following -

  1. uninstall unreal 5.3 completely and reinstall
  2. uninstall visual studio and reinstall
  3. added correct MSVC
  4. added all components and SDKs needed
  5. deleted the build configuration file from c drive
  6. uninstalled quixel plugin

here is the .vsconfig file, full logs and other relevant stuff of my vs - HERE

its been over 3 days now and this is just soo extremely annoying and disappointing that it all is designed in soo un-userfriendly way. I would greatly appreciate any solution to fix this.

thank you,

Hi Shrader, did you compile 5.3 source once (without the extra plugins)?

If yes, move your plugins into the Engine/Plugins/Runtime folder and start the project. If the problem persist the error suggest that plugin files are missing.
