Question about japanese map fog plugin

Hey, I purchased a couple of tile packs from the shop and the sample demo game comes with a cool plugin that adds map fog called BMSP_Mapfog.js but having everything in Japanese (including the readme, switch names, variables, etc) makes it sorta difficult to get set up. I tried translating as much as I could... but meh.

Is there a similar plugin that is maybe in english? o_O

Edit: Here is the readme translated

* Map notes:
* <Fog% n%:% name%,% sx%,% sy%,% opacity%,% z%,% blend%,% switchies%> # Add fog to the map.
*% n%: The number of the fog. Please specify an integer of 1 or more.
*% name%: The name of the file to use. (initial value: '')
*% sx%: Speed in X direction. (Initial value: 0)
*% sy%: Speed in Y direction. (Initial value: 0)
*% opacity%: Opacity. (Initial value: 255)
*% z%: Z coordinate. 0 is just above the distant view, 1 is right under the picture, and 2 is directly above the picture. (Initial value: 1)
*% blend%: It is a synthesis method. 0 is usually, 1 is addition. (Initial value: 1)
*% switchies%: Display condition Switch ID list. Specify the ID of the switch you want to set as ":" separator. (Initial value: not specified * always displayed)
* ※ Label of memo can be changed by parameter.
* * Fog numbers must be present in order from 1 for each map.
* ※ Each parameter except% n% can be omitted. If omitted, the default value is used.
* In addition, all parameters after the omitted parameters must also be omitted.

This part is what I may not be getting, and I don't know for sure if I need to set up switches and/or variables. At first glance it doesn't seem like I should.

* * Fog numbers must be present in order from 1 for each map.

Edit: Nevermind, I needed to translate the parameter in the plugin from the Japanese word for fog to english... It seems to be working now. -_-;
