Is there a way to display the camera preview in a portrait view?

So I’ve decided to make a mobile game using the unreal engine. I’ve started with setting up the player camera but I encountered a problem/annoyance. The game is meant to be played in portrait mode, I’ve already correctly set up the build to use my desired aspect ratio however when selecting the camera the small picture in picture preview display in the viewport keeps displaying in a landscape format.

Is there any way to modify the preview aspect ratio?

Select the camera and search for something called Aspect Ratio Constraint (or thereabout), this should request the preview to respect the destination view. Untested but fingers crossed!


Other than that, the Editor Preferences - Viewport has some settings for the preview cams but I’m unsure whether that’s useful here - never fully explored those myself bar the size of the preview.

Found it. It’s called the Constrain Aspect Ratio - once ticked it allows you to control the preview aspect ratio, it seems. The dropdown options are uninspiring so you may need to punch in values manually above.

Thanks for the help, when I’m done with my project should I undo the constrain aspect ratio or leave it as is? I currently have it set to be 0.5625 which is a 9:16 aspect ratio

I believe this should be fine as is but you will want to test it on more than one device, surely.
