I have tried lots of times and still end up with the same error ‘Unknown Cook Failure’ and highlighted parts that may seem to be the error (the failed to find tutorial files is also weird, how to solve?).

Running 4.14 version and cooking for android ETC2

I have tried with a blank project and it also gave me the same error.

cook log: UATHelper: Packaging (Android (ETC2)): Project.Cook: ********** COOK COMMAND S - Pastebin.com

Some highlights

UATHelper: Packaging (Android (ETC2)): UE4Editor-Cmd: [2017.01.11-09.36.00:634][ 0]LogTexture:Display: Building textures: WhiteSquareTexture (AutoETC2)

and

UATHelper: Packaging (Android (ETC2)): UE4Editor-Cmd: [2017.01.11-09.36.27:534][ 0]LogWindows:Error: Assertion failed: Mips.Num() > 0 [File:F:\411slnue4\UnrealEngine\Engine\Source\Runtime\Engine\Private\TextureDerivedData.cpp] [Line: 1233]

Thanks

Additional Edit: Using UE4.14 Version, Android CodeWorks 1R5, Visual Studio 2015

HI inferno,

Before all the error messages, there are a bunch of ‘Can’t find file /Game/PuzzleBP/PuzzleOverview’ and ‘Failed to Load’ errors.

Maybe if you deleted those files from your project and your project still refers to some of the assets from the deleted file ?

Thanks

Hi, those files were the tutorial files that were generated when using the puzzle blueprint template, I have deleted them and used ‘Fix up Redirectors’ but the error is still there, and the thing that is even more confusing is that when i am packaging a blank project it still shows the can’t find file /game/puzzlebp/puzzleoverview which is in a totally different project…

However, these aside I would like to know why i am getting the main error **Assertion failed: Mips.Num() > 0 ** both in my project and a blank project.

Thanks

I have fixed the ‘Can’t Find File’ errors now, only left the Assertion failed: Mips.Num() > 0 which i can’t solve.

Alright, i have fixed the issue ‘Failed to find compressor for x’. After downloading the android SDK i just had to rebuild the ue4 engine, which gives the compressors.

Also got same error on Ubuntu… Im using release branch UE4, official android sdk (API 19) + latest android ndk (not strange tool codeworks).
