Hello.
In Update, after you have set overlayBackAlpha for all tiles, you need to call OnlineMaps.instance.Redraw().
Ahhh of course I see.
Thanks very much.
What about if I wanted to set the alpha to 0 after the start btw?
It seems to lock to lock to 1 even if I set it in a few places in the start

]]>The issue I'm facing is that the overlay always shows no matter what the alpha is set to.
It is worth noting that I don't have the full content to use yet so I've only been using one zoom level of another map, but I don't think that should affect it.
Am I missing something with regard to how this works? Code is below but I believe this would happen with the unedited code from the overlay page.
Thanks
