As far I can tell the content cooking works good. I built a apk with very minimal scene and ~85% of size is this lib libUnreal.so
(its ~300MB extracted from apk). I tried to remove some plugins in hopes to get down the size, but I guess I removed something needed, so it doesn’t work any more (clang++.exe: error: unknown argument: '-fforce-emit-vtables'
) and there is no button to reset default plugins.
