I just released Pano2VR 2.3 beta4 which is mainly a bugfix release for beta2 and beta3.
The changes are:
- Sound: External *.mp3 files
- Bugfix: Skin editor could not be launched from the Flash settings page
- Bugfix: Patch Tool ignore the image gamma
You can download the new version as always from the Pano2VR download page.
