You could pull in Google Street View panoramas (with proper API credits) as tour nodes, edit them with your own hotspots, and export back to Street View — or just mix Google’s imagery with your own 360° photos.
Instead of embedding a 50MB video inside the tour (which bloats the download), you can now link to a YouTube, Vimeo, or even a raw MP4 URL. The hotspot acts as a video player without leaving the 360 environment. For audio, background ambisonic soundscapes can now be looped without reloading when the user changes nodes. 3dvista virtual tour pro features 2021
