Android : Packaging size

Hello, i’m working on reducing the packaging size of my app but i encounter some problems.

So I’m using the [project]/Saved/Cooked/Android_ETC1 folder to see what’s in my project (after packaging for Android_ETC1 ofc). There is 2 SubFolder here, Engine and ProjectFolder.

Problem is the engine folder(43mb) is bigger than my project folder(29mb) even if i have disabled “package engine content” in settings and removed all i can that was referencing the engine content. The heaviest file is DefaultBloomKernel.uexp (32mb). So i searched and i found this

https://forums.unrealengine.com/development-discussion/android-development/118929-defaultbloomkernel-uexp-what-is-it-and-is-there-any-way-to-reduce-its-size

I tried the solutions proposed but this still doesn’t work. This file still being created.

So i have questions :

  1. If this file is in the “cooked” folder, this mean it’s also packaged in .apk and then make it bigger right?
  2. Is this file generated because I activated Bloom in my project? (I suppose yes, but when i remove Bloom from project settings, i still have the DefaultBloomKernel.uexp generated)
  3. How to remove it??

Any help is appreciated
