It’s all in my videos, yo. (well, the last EXTRAS video)
I make a settings save file that gets saved when the user hits apply (which also executes all the console commands), and I load it at Event Begin Play and cycle through the console commands with the values in the save file.
You’ll need the sg. commands rather than the r. commands (except for r.screenpercentage, the sg version doesn’t seem to work) on the scalability page. I don’t remember them off by heart but you can find them by dumping the console commands. The values you need to put in the sg. commands might be different too, I believe the sg Antialiasing takes a 0 to 3.
I still haven’t recieved an answer in the AnswerHub from any engineers regarding interacting with the .ini files. I swear I almost managed to cast to one once, but I haven’t recreated it.
In the videos when I create the default save file (if no save file exists) I set defaults in the array, but I’m wondering if I could execute the Scalability Auto command then find out the values. I’m not sure if just doing the console command without a number would return a value, or if I’d be able to check that number via blueprint.
