Creating a 360 degree skybox in HDRP

Hi there. I am trying to make a 360 degree skybox in unity HDRP by using a 2:1 HDR image but when I do the image is not wrapped around spherically but instead is only visible from above the horizon.below the horizon is just kind of smeared out. is there any other way I could acheive a full 360 degree skybox? It works perfectly in blnder for example when I use an envoronment image. thanks!

Ha, I found the solution, I had fog turned on! Doh! Turned it off and now its spherical.

blnder?
