It's not yet officially possible to export Depth channels for panoramas, but that is on our agenda as a feature request, same goes for the ability to export multiple panoramas at once, which has not been implemented yet with 2.7. I'm adding your feedback and upvote to both topics though!
Thanks, Demian. Yesterday officially all of my node based 360 VR Tours AWS hosted went ruined for Oculus Quest / Go vieweing: last update of Firefox Reality doesn't play Tours made with 1.19 release of krpano, at least without rewritting the xml files. Oculus browser didn't play them from time ago, and Firefox Reality was the last bullet, so I'm thinking how to release new Tours for VR playing. Panotour Pro finally is not the tool. By now krpanotools and some tricking in the xml code does the job.
