I have this idea for a game where the monitor is split into four viewports, letting you see in four directions at once. It's quite possible that it's going to be unplayable, but I have thought about it for so long and really want to try it!
I guess I should use HBoxContainer and VBoxContainer to manage it, and a ViewportContainer should contain the Viewport which should contain the Camera. So far so good.
But when I run it, I just get a grey screen.
Does anyone know what I may be doing wrong?
