I have a simple outline post processing material that looks fantastic at r.ScreenPercentage 100, but at r.ScreenPercentage 50 completely falls apart. The actual size of the “pixels” or fragments that are rendered is larger with a lower screen percentage, so I would need my sample offsets to be larger accordingly. How can I access the ScreenPercentage in a post process material?
I don’t think you can, but you can pass it as a parameter to a material instance of this PP or, more easily as part of a material parameter collection
Okay I had a suspicion that that was going to be the only way to do it, though I was hoping there was a material node way. What node do I use to access ScreenPercentage in blueprints?
Well, if the user is changing the screen percentage, you’re in control of that, and know what it is… 
I had a quick google, looks like it’s done with the console commands node, so you can just keep track of it.
