FEATURES
This plugin allows you to add a simple shadow to events and player/follower characters on the map.
Shadows can be specified via notetag in an event, or a comment on an event page if you need only certain pages to have shadows.
You can disable all player or event shadows with plugin or script commands.

Thank you for your plugin.
I found one problem.
When I view the event using the switch, it is not shaded.
Does it happen in the plugin demo?
I saw it happened in your demo too.
I added an actor for events.
first switch on, then from a transparent event into the second person appear but the shadow isn’t.
Do you have the shadow notetag on the new page? I need more information as I cannot replicate this.
