Mods are ways for you to tweak your UI or change looks of in-game models like Mounts, Costumes and others. Mods will only change how you see a model, and not for other people.
Unfortunately mods are only supported on the PC version.
These mods change the look of non-collection items that you see in game, like Decorations or Resources you can pick up in Adventure Worlds.
