Want to express all your complicated emotions in 3D? Now you can with /emote in game! Yes, you really do the animated emotes in game, no mods required
Note: To see the emotes, you must be in Minecraft 1.18+ (Java) and be using the latest version of the TLB Resource pack. Other players will still see your emote if they are not on 1.18+ Java with the Resource Pack, but your skin won't look correct.
