Here is the answer I got from Michael Prinke, which allowed me to solve this issue :
I got your Email regarding the chunks/OBBs. In DefaultEngine.ini, you need to add a series of OBB filters, like so:
[/Script/AndroidRuntimeSettings.AndroidRuntimeSettings]
+ObbFilters=“-pakchunk1”+ObbFilters=“-pakchunk2”
+ObbFilters=“-pakchunk3”
+ObbFilters=“-pakchunk4”
+ObbFilters=“-pakchunk5”
+ObbFilters=“-pakchunk6”
+ObbFilters=“-pakchunk7”
+ObbFilters=“-pakchunk8”
+ObbFilters=“-pakchunk9”
This will exclude pak files from your OBBs that include any part of the provided strings in their names. I’ve added this > to the GooglePAD docs, as it affects that solution too, but I’ll find a home for this in the general patching docs as well > so it doesn’t get overlooked.
