This is useless because it says “For Install-Time assets, you do not need to make any changes.”
Yeah well, if you do not do anything special, it doesn’t work.
It opens with:
" If you want to use GooglePAD for install-time assets, you also need to navigate to Platforms > Android > APK Packaging and disable Package Data inside APK . The main .obb file will then be delivered as an install-time asset pack automatically."
Keyword “Automatically”. Yeah, not the case.
Also, this 5.4 documentation still states: “This workflow will be streamlined further in Unreal Engine 4.26.”
