360 Panoram Image as Background

Good day all together

I have a small problem. I want to create a background with a 360 panorama image. But it does not look good. I have already tried two things:

  1. sphere with the 360 texture. The image is getting distorted and no edge is straight / parallel.

  2. HDRIBackDrop BP. When I import a HDR image it gets too pixelated because Unreal is compriming the image.

Do you know a better solution?

thank you in advance and have a nice weekend
