I have turned off msaa and android msaa from my project settings.
Even in defaultengine.ini in config/android I added
[SystemSettings]
r.MobileMSAA=0
r.DefaultFeature.AntiAliasing=0
r.PostProcessAAQuality=0
In the editor it looks fine and AA is off. My game is not supposed to have AA on.
But when I package it to abb and run in android phone it looks like image was softened and some sort of antialiasing was applied. My game is closer to release date and I need this resolved asap
