HTML Templates
Pano2VR outputs an HTML file to playback the web output in a browser. This is just a template and can be edited to your project's needs.
Pano2VR ships with a number of templates and they can all be found in the HTML Template directory. You can edit the templates or even create your own.
You can pick which template to use in the HTML pane of the Web Output Properties. You can also edit the template from this location by clicking the Edit Template button.
