UE4 build Error_UnknownCookFailure
Hi, I can play my project in the editor perfectly. But when i try to build it, i got build error which prevent me to do it. Strange error like failed to load this file or this file. But UE4 is looking to the correct path. I've checked all my blueprint to see if there was an error inside, but unreal doesn't detect any. Here is my build logs: link text
I've also tried to remove the binaries, save and intermediate file but without results. If you have any idea, Thanks in advance.
EDIT: I also run a checkmap on each level and i didn't get any error (except i need to rebuild light on one or two level)
You are experiencing an ensure error;
You are setting an attachment rule to some component that the engine doesn't like you doing (doesn't state which component).
Hope that helps. Cheers,
