What engine content is in use and what can I blacklist?

Hi.

In my saved/cooked folder there is a lot of engine content that I probably don’t need. I know you can blacklist parts with 4.9, but I’m not sure which files I can exclude. I probably have all these files because I started the project from the c++ puzzle template. The game is finished now so I can’t really change it unfortunately. Is the best way to just guess and see what breaks the game?
Thanks.

Here’s the folder:

I tried using the blacklist, but it doesn’t work. apk is still the same size. Here’s my blacklist file:

Hi Pesk92,

First, the paths should have forward slashes and second you don’t place the full path, but the relative path. The example above would be:


../../../Engine/Content/Tutorial/
../../../Engine/Content/MobileResources/
../../../Engine/Content/MapTemplates/
../../../Engine/Content/Maps/
../../../Engine/Content/EngineSounds/
../../../Engine/Content/EngineResources/
../../../Engine/Content/EngineMaterials/
../../../Engine/Content/EngineDebugMaterials/
../../../Engine/Content/EngineDamageTypes/
../../../Engine/Content/EditorResources/
../../../Engine/Content/EditorMeshes/ColorCalibrator/

You will need to experiment with which files you may safely remove, but I’d recommend leaving EngineMaterials at least; at minimum it will need WorldGridMaterial.uasset. You may list individual files if needed instead of directories. The blacklist works by matching any filepath that starts with any of the entries which is why just ending / removes all the files in the directory and all subdirectories.

Hi kiranmaya,

The default is to build for ARMv7. If you use the GitHub sources, you can build for x86 by turning on the checkbox for it in the Android Project Settings. The two architectures will generate different APK files.
