I extracted the pak file and I can confirm the files I want to get rid of are there. So the blacklist isn’t getting recognized.
In the 4.12, looking with 7-zip, both the lib folder and the engine content folder are about 10mb smaller. I’m guessing the size difference is the new content from 4.13 making it’s way into the apk even without being used.
There is no mention whatsoever to the blacklist in the package log.
I did the fix redirectors and I only have one map with one blueprint, I made the game like tappychicken, all in one. No apparent errors.
Although when looking at the reference viewer and navigating around I see stuff I’d never be using like VR and worldgrid materials, the sky materials as well, connected down the line to the level. But I don’t know if seeing them in the reference viewer means it’s actually using it.
Anyways the blacklist should just keep it out even if used.
I tried deleting the folders you said but that just destroys everything. I still have the assets but I have to reassign everything. So for now I just went back. I may try that if all else fails.
