Updated to 4.15 and now PackagingResults:Error: Error Unknown Cook Failure

It seems like there is something wrong with your “GatlingGun_AnimBlueprint” file. Maybe a variable named “Gatling Spin Speed”. Maybe you could check it.
And some file may Failed to compile(i.e. HDRI_Epic_Courtyard_Daylight_Mat…).

Howdy all;
I updated to 4.15. I tried to package my VR game for windows 64. I got the following error.

UATHelper: Packaging (Windows (64-bit)): Program.Main: AutomationTool exiting with ExitCode=25 (Error_UnknownCookFailure)
UATHelper: Packaging (Windows (64-bit)): BUILD FAILlink textED
PackagingResults:Error: Error Unknown Cook Failure

If anyone happens to know what might cause this problem I would be so very grateful.
I attached my log

Hello lennysunreal,

After looking through you log, could you try clearing up the error mentioned by wukakuki (error provided below). After this if you continue to get errors, could you then post your new logs after the error below is cleared up?

LogBlueprint:Error: [Compiler GatlingGun_AnimBlueprint] Error The property associated with Gatling Spin Speed could not be found from Source: /Game/Mine/Weapons/GatlingGun/OldGatlingGunJunk/GatlingGun_AnimBlueprint.GatlingGun_AnimBlueprint

I’m so sorry for the delay. BUT! You are my hero! Thank you so so very much :slight_smile:
