How to create a customized Environments experience in Vision Pro?

Really new to the Vision OS coding. We tried to create a customized experience just like what apple did in the system Environments or the Disney did in its app ( it seems they put user in a carefully made 3d model). Do we need to make a 3d model for the environment and how to put it around the user sphere like the skybox?

did you make any progress on this?
