Does the blacklist work in UE4?

I use example from TappyChicken project and it works well.

Here is PakBlacklist-Shipping.txt sample:

../../../Engine/Content/EditorMeshes/ColorCalibrator/
../../../Engine/Content/EngineDebugMaterials/
../../../Engine/Plugins/Runtime/LeapMotionController/
../../../TappyChicken/AssetRegistry.bin

Full path must be [Project]/Build/Android/PakBlacklist-Shipping.txt.

May be you use incorrect file name case (PakBlackList-Shipping.txt instead of PakBlacklist-Shipping.txt).
