Weather Extensions to default RMMV weather system. And with a little configuring you can add fully customized and automated weather system!
This is what this plugin does:
Weather can be inherited to battle scene
Storm, blizzard and rain may have BGS (volume varied by power)...
It's still early days, and I was going to keep this under wraps until development is a bit further along, but I'm just so damn proud of how robust the integrity-checking in this plugin is that I have to share it.
