LogPackageDependencyInfo:Warning: RecursiveDeterminePackageDependentTimeStamp: Failed to find linker for C:/Users/kalan/Documents/Unreal Projects/MyProject3 4.15/Content/NewFolder/Blueprints/Smoke.uasset

Looks like Smoke.uasset is corrupt.

I tried deleting Smoke.uassets but still does not work:

link text

Source\MyProject3\OnHit.cpp

It seems this file doesn’t have any headers. Investigate this file, if you can’t find the solution, just give us information about this file! <3

Thanks, once I deleted OnHit.cpp, the “Error Unknown Error” stopped, but know I am getting a Unknown Cook Failure:

[link text][1]
[1]: 201519-unknown+cook+failure.txt (357 KB)

I would recommend deleting your intermediate, config and saved files if you haven’t done already and try fixing your redirectors. In case it’s still not working, you should check the following files and fix or delete them if you don’t need them anymore:

Content/NewFolder/Blueprints/NewBlueprint2.uasset

Content/NewFolder/Blueprints/MyTPSGame.uasset

Content/NewFolder/Blueprints/Cube.uasset

Content/NewFolder/Blueprints/NewBlueprint2.uasset

In case you can’t see them in your editor, make sure to fix your redirectors and manually deleting those files in your windows explorer.

There is also a message about S_LightError.
I already posted an answer on another question, so if you encounter it again, also make sure you tried this solution.
