Make Camera View from where the center of the spherical rendering will be. I recommend 4 feet from floor for interiors.
Test render, confirming lighting, materials, and exposure are correct. Up to Revit 2018, render settings Lighting & Background must be set for each new view, even if it was copied from another view.
Select border of View, switch to a plan View and Copy Camera View to the next position
(or Duplicate Camera View and Move)
Rotate, placing Center where the camera is
Rename View(s) as appropriate if needed
Sign into an Autodesk account from Revit
In the View tab, do Render in Cloud
Select views to render as Panorama
Wait, but don’t leave your computer, yet!
If there are any unreferenced rendering texture images, it will wait for you to hit OK forever with this less-than-useful dialog
Caveat: I suspect that custom rendering texture image files must be named without dots, commas, ampersands, or other non-standard characters in their filenames. They may not be uploaded if that is the case.
Go to your Render Gallery
It is clever that the rendering can be seen in-progress through the website. Cancel Rendering if needed.
Confirm that the rendering is proper with the 0-credit version, then choose higher-quality settings and pay Autodesk Cloud Credits (around $1 each after free ones are used). Render Quality Final, Width 1024 px is adequate for roundme.com on phones.
When completed, download as Equirectangular
Make a folder for each rendering and Extract image.jpg from the Zip.
Roundme.com has a generous free tier and makes publishing panos easy. Log in and click CREATE TOUR
Drag and drop more equirectangular images
in Roundme, drag an image from one of the thumbnails into another scene and place the hotspot
Set Custom view direction that makes sense as if the viewer has moved position
It will look like this
Info hotspots are also easy to make. Drag the i icon onto the scene and fill in the form
When ready, turn on Published and SAVE
