- 6 new presets (aurora, void, blood, ash, smog...). Quality setting. Fog respects screen tint.
- v3 saves keep working.

I've noticed the wake seems to always be off center similar to the problem described my @breathdev, I'm not using any other plugins so I'm not sure what's breaking.
Hi. I really like the idea of the plugin, but I've encountered a couple issues of when using the MZ version.
i. The wake sits off centre and always appears 4-5 tiles NE east of the main character. The plugin help window is empty. Is there a quick-fix to offset the wake 4 tiles to the right and down?
ii. When scrolling the map horizontally, the fog starts to glitch out as if there fog image is being flipped horizontally every 2 to 3 frames repeatedly.
What an amazing plugin! The effect it creates in the game is truly better than any other fog effect I've ever seen.
I'm currently using RPG Maker MV3D for some of my maps. I noticed that your plugin doesn't work very well, as it seems the Fog Rim area misses the player's correct position. It would be incredible if you could make this plugin work with MV3D as well.

Yo! Thanks for the huge compliment!
MV3D completely changes the camera math, which breaks the fog's position.We're going to make a special MV3D-compatible version.
Drop your Discord or Twitter/X below. Once it's ready, I’ll send the custom build straight to you so you can test it

Defo let me know when there's an MV3D version, I'll also snap that up.
