It would be a great addiction for Studio to have motion-enabled videospheres and 360-images sphere/skyboxes like the old A-Frame / Three.js based projects like
and
(which are now available only to paid subscriptions).
The door-portal is a Studio project quite similar to what I mean, but it uses a Splat instead of a 360 image - which is nice, but you might not have a splat to use and sometimes you just want to use a 360 still image linked to accelerometer motion.
Just for the records: I replicated it. World Effects template, add a sphere, make it big, revert normals by setting the material to βBackβ, disable SLAM in Camera so you are always at the center of the sphere, assign a 360 image to the sphere material.
