Select “Environment” and click “Upload a 360º image”. It is important to plan the order of your scenes in advance as you will place your 360° images in the order that you have defined for your virtual tour itinerary. Select the 360° images you would like to import into your space and upload them. UPSers
I don’t use the skysphere because its mapped hemispherically
Most 360 images a equirectangular projection
you map them to a blank sphere, make the sphere larger than the scene and turn off its shadow casting and make it unlit with the texture in emissive.
You can also map a stereo 3d image to the environment sphere, look at a post in the open xr forum I made about that.
when looking at the sphere the eyes see different LR textures.
anyways
don’t use the sky sphere bp, just map the image to a normal sphere, if you want to use displacement you will need to import a subdivided sphere, but for most images you can just map the material to a sphere.
I do it all the time.
