Project: Paper2D

[ALECA]

Hey , guys.

I am not sure if is right place for post.

My Paper2D game uses 7 atlases and my apk looks really big. Yes, i found out that UE4 has some issues packaging android apps and there are some strategies to decrease 15-20MB.

But something catches my attention:

MainFrameActions: Packaging (Android (ETC1)): UnrealPak: LogPakFile:Display: Added file “Mythoclast/Content/Assets/Sprites/Textures/mythoclast_battle_1.uasset”, 22370950 bytes.

Those are my texture atlases and they are 10 times bigger than textures on disk.

Why is happening? Is there a way to decrease their size (compression or any other option)?
