Polygonal filled hotspots

[oq.agency]

Greetings! I'm new to VR Tourviewer and I'm currently using the demo version. I watched a demo tour with the program's features. I want to make a polygon hotspot filled with blue or red when I hover my gaze, as well as the polygon edging, the same as in the demo tour. But I didn't find any instructions on the site in the FAQ section. Please tell me where I can read about it?
P.S.: I use Pico Neo 3 PRO device.

You can set the desired default look of the polygons in the 'Hotspots' rollout of the Pano2VR Output settings.
Then you can decide per polygon if you want to use the default colors or want to use a different outline and fill color.

Note that the 'Alpha Channel' value in the color picker determines the transparency, where 0 is invisible and 255 is opaque.
