Hello
VR Tourviewer can recognize top/bottom or left/right stereoscopic videofiles (including 180 and 360 modes).
But what about stereoscopic still images (in popup windoows, not in additional panoramas)? Same filenames and tags as for videos are not working (using Pano2VR)...
This will be supported in the next update of VR Tourviewer.
You will be able to use a stereoscopic L/R pinned image and add _stereo to the ID in the Properties of the Image in Pano2VR.
Release date is not known yet but if you need this feature urgently, it's possible to include this feature in a whitelabel/customized version of VR Tourviewer: https://www.vrtourviewer.com/order-white-label/
