How to edit the fov of cubemap scene capture

I want to make a 360 screenshot for my scene like this.
But i want to edit the fov of the cubemap capture .If cubemap capture cant edit fov, is there any way to edit fov when capturing a 360 screenshot in ue4 ? Thanks a lot

How would that even work? Cubemaps have an FOV of 360º, if they didn’t then they wouldn’t be cubemaps.
