I don’t see this option at all and it really, really irks me.
I want to be able to set the in-editor view-port to some standard sizes on the fly.
The internal PIE window, to be clear.
We need 3 or 4 standard buttons. 2k, 1080p, 720p, 800x600 legacy.
Meanwhile, You can get the engine to print out values by hacking this into an empty actor tick event.
When you start playing in PIE you will get a printout. You can then manipulate the viewport size until you are happy with the values you get.
