How to make HDRI Image In Unreal engine?

I use ‘Panorama capture’ plugin, because i want to have backgroud image to use for HDRI Backdrop.
My world is Captured, but the same two images were attached up and down.
I found out that the render image used in VR is divided into that way. But I don’t intend to use this image.

I want an HDRI image for use in a mobile version that takes my world as a landscape. for performance.
