Panorama disappear and reappear, again and again

[k_iwan]

Dear Worldviz team,

Since I upgraded to the recent version of vizard, I noticed that somehow my simulations' skybox switches back to plain blue colour and again switches back on the skybox.

In short, sometime I get to see the skybox and later it may disappear completely.

I follow tutorial from "Tutorial: 360 panoramas"

Any suggestion will be greatly appreciated.

Kind Regards,
Iwan
