AR, divide screen on mobile device


I am very new to UE and not a programmer. I would like to know how I could divide an AR rendered image into two on the screen of my mobile phone to obtain a side-by-side screen? I need to simulate as if it were stereoscopic to use is as a head-mounted screen. I know that there will be no real depth in the image because the mobile device only has one camera and the rendering is not stereoscopic either. I just need to divide one image in two to see it through cardboard. On both sides of the screen, there will be the same image.

I was thinking about using the UNREAL4AR plugin because it looks like it can be used without coding, but I couldn’t find any information about dividing an image. I am very open to any suggestion you can give me! Maybe another plugin can work better for this purpose?

Thank you so much!
