ModdableDecalGroups.MD

To group your decals (Tails or Banners), use DecalGroupSpec entries by creating *.blueprint.json files in your mod.

For example:

{
    "DecalGroupSpec": {
        "Id": "BannerGood",
        "TitleLoc": "LV.MDG.BannerGoods.Goods",
        "Category": "Banners",
        "Order": 900,
        "DecalIdExacts": [
            "CustomBanner.Antidote",
            "CustomBanner.Badwater",
            // More...
        ]
    }
}

• Id: Unique identifier for the decal group.
• TitleLoc: Localization key for the decal group title.
• Category: Which category the decal group belongs to (e.g., "Banners" or "Tails").
• Order: The order in which the decal group appears.
• DecalIdExacts: An array of exact decal Ids to include in this group. If any Id does not exist, it's simply ignored.

You can also use DecalIdPatterns to match multiple decals with a Regular Expression pattern. For example:

{
    "DecalGroupSpec": {
        "Id": "BannerAlphabet.Capital",
        "TitleLoc": "LV.MDG.BannerAlphabet.Capital",
        "Category": "Banners",
        "Order": 1010,
        "DecalIdPatterns": [
            "CustomBanner\\.01BasicCapital.+",
            "CustomBanner\\.05SupplementCapital.+"
        ]
    }
}

You can combine both DecalIdExacts and DecalIdPatterns in the same group, and decals will be included if they match either criterion. A single decal can also appear in multiple groups.
