If you are still not satisfied with the build size, there is another option - to rebuild the engine with disabling unused but heavy modules, which are also included when the project is packaged. /./Engine/Plugins/Editor/SpeedTreeImporter/Content/SpeedTree9/game_wind_noise.ubulk /./Engine/Plugins/Runtime/LeapMotionController/ /./Engine/Content/Internationalization/icudt64l/region/ /./Engine/Content/Internationalization/icudt64l/zone/ /./Engine/Content/Internationalization/icudt64l/unit/ /./Engine/Content/Internationalization/icudt64l/lang/ /./Engine/Content/Internationalization/icudt64l/translit/ /./Engine/Content/Internationalization/icudt64l/coll/ pak file and get to the file, open the console in the Engine/Binaries/Win64 folder and write the following command: To do this, you will need to open the file as an archive located in the “assets” folder inside your game’s pak file. The following example is relevant for the Win64 platform.įirst, you need to figure out which specific assets you need to exclude. You can also remove unused assets that are packaged with your game but are never used. It depends on each project, but I came up with the following list: I recommend going to the Plugins tab and disable the ones you don’t need. It is likely that your project contains unused plugins that are enabled by default. This will slightly reduce the size of the shaders and hence the build size: If you are not using moving point lights, set “Max Movable Point Lights” to 0. You can also enable sharing material shader code and use of shared material native libraries, which will slightly reduce the size: You can exclude some unused editor assets and compress the required ones like this: The first thing you can do is set Build Configuration to Shipping and enable For distribution: There are many switches in the project settings that will help reduce the build size.

I will show you how I managed to reduce the size of my Android game from 150MB to 50MB. But on mobile platforms, this issue is most acute. There are multiple ways to reduce the build size.
