Hello!
I'm new in RPG maker and I'm working on a game for my friend.
I'm using RPG Maker MV with Yanfly plugin Yep_PartySytem and AltMenu3 by Sasuke Kanuzaki, Yoji Ojima (link below) which is adding custom picture on menu.
I can add picture on everything (item, skill, equip etc.) but it's not working on Formation.

I can't add the picture, because there is not value for it. I've tried to "repair" the .js file and I've also added the value parameter for Formation (+ few things into the .js file)

but it moves the whole menu somehow and didn't show the picture.
I've added between Status and Options these (bcs i thought it will work bcs it look the same)
* @param bgBitmapFormations
* @desc background bitmap file at formations scene. put at img/pictures.
*
@Default
var bgBitmapFormations = parameters['bgBitmapFormations'] || '';
var _Scene_Formations_create = Scene_Formations.prototype.create;
Scene_Formations.prototype.create = function() {
_Scene_Equip_create.call(this);
this._changeWindow.opacity = 0;
this._removeWindow.opacity = 0;
this._revertWindow.opacity = 0;
this._finishWindow.opacity = 0;
};
Anyone know what I'm doing wrong? Or have better way how to add picture on menu?
Thanks a lot!
(Sorry for grammar mistakes)
