An animation package is a purchasable bundle on the avatar shop that changes a player's R15 movement animation. Animation packs were announced on January 19, 2017, by tarabyte on the R15 Avatar Animations blog. Each animation pack contains Run, Walk, Fall, Jump, Idle, Swim, and Climb animations. These animations are applied to the character in-game; however, the idle animation is also shown if the user has one equipped while using the R15 rig. All initial animation packs were released in January 2017, with the Rthro Animation Package being released in September 2018, and finally the Oldschool Animation Pack being released in July 2020.
- The Robot Animation Pack and Oldschool Animation Pack are outliers from the rest of the animation packs, having Animation Pack at the end of its name rather than Animation Package.
