Hey CookieBadger. Thanks for very fast answer. So I see I don't have any other option than buy this plugin. I tried other plugins like that, but no one was working as I expected. I think with this plugin will be different.
Actually I have one more question. Can I use this plugin to make some linear close levels to horror games? Like, I can, but if it's convienient? Or I should use some other plugin to more advance making small, close and linear rooms / areas where player can move etc?
