Render texture on slim plane

I’m working on a project where I’m using a render texture to show the view from a camera. I’ve placed the render texture on a plane but since the plane is very slim the view gets “squished” making it very distorted. Is there a way to keep the render texture the original size and instead choose the part I want to show? Something like this:


I started learning Unity last week so If you could give a code example or point me to a tutorial that shows how to do it I would really appreciate it.

You need to set the aspect ratio to match your render target. So if your side strip is 100x800, you want to set your Camera.aspect to 100/800 or 0.125.

[EDIT] Oh, you’ll probably also need to shrink the Field of View then to frame whatever you’re showing correctly. A wide FoV (eg. 60 degrees) is like having your eye right up to the slot, a narrower one (eg. 5 degrees) is like looking through the same slot from across the room.
