I am trying to view spherical renderings or photographs within my level. My thought was to grab a spherical image, create a material, put that on a sphere, and put a camera in the middle of that sphere, similar to a skybox. That seems to work fine, but the image seems to get really distorted, specifically straight lines become squiggly. I’ve tried messing with the texture’s compression settings, but nothing seems to fix it. Is there a fix, or maybe a better way to go about doing this?
Awesome! Thank you so much
There’s a default setup for this now, but I can’t recall how it works.
In the meantime, import the HDR as a texture. Make sure to change
‘maximum texture size’ = 1024
mip gen settings = no mip maps
texture group = skybox
Then make a two sided unlit material like this:
The HDRI param cube node is set to the texture you read in.
Put a BP sky sphere in the level ( default UE thing ), and make this the contruction script:
This puts the material on the sphere.
Tell me how you do…
Naturally, once I’d post all that I remembered the easy way… 
( although I just tried this and it didn’t work great… )
EDIT - Ah! - change the mesh in the details panel to skybox
