Ulterior Motives
by okipiak
Ulterior Motives reworks the Invisibility effect so that being invisible carries side effects, and adds Fabric enchantments for uncovering unseen players and entities.
What it does
Under the mod, invisibility is no longer a free cover. An invisible player's potion particles can be shown or hidden, mobs can detect the player, and the name can be censored with obfuscated text in chat, on the server player list and in join and leave messages. Each of these behaviours is a separate option that can be switched on or off.
The mod also adds two enchantments that counter invisibility. Curse Masking is a curse for helmets that erases the wearer's identity, and Trailwatching is for spyglasses, revealing invisible entities and leaving footprints that appear beneath the spyglass user after a short delay. Only the helmet works with other enchantments. Both the Ancient Cities and the Pillager Outposts are where the enchanted books can be found.
Installation needs Fabric API and Cloth Config API. Enchancement is optional. Ulterior Motives runs on client and server, so the server and every player need the mod. It is published for Fabric only, for 1.20.1, and the latest file is 1.0-1.20.1, dated 2025-07-18. The code is not open source; the author holds all rights.
Key features
Invisibility side effects
Invisibility changes how the player is seen and treated, so the effect is no longer only cover.

Chat, the player list and join and leave messages can censor an invisible player's name, and each use can be switched off.
Mob detection
Mobs can detect invisible players, and this behaviour can be turned off in the settings.

How it compares
Particle Plus is a client-side only Fabric mod for 1.20 – 26.3 under All rights reserved, so it is not open source and only affects how particles look. Hide Invisible Armor is client-side only under the MIT License and covers 1.20 – 1.20.3, so its scope ends before this mod's 1.20.1 release. See Invisibles With Armor Hitbox is client-side only under the MIT License for 1.16.5 – 1.21.4, and it changes the armor hitbox rather than the effect itself.
