Change avatar ↺ - Change emote ↺
Emotes are animation sequences for avatars’ skeleton bones, which are defined in a transport file, usually in .glb, or .gltf formats. An emote can include sound, or even an animated 3d geometry attached to it. For more information check Adding Props and Sounds to your Emotes .
There are a selection of free default Emotes that are available to any user, but Decentraland also supports the creation and use of custom Emotes that are represented by non-fungible tokens ( NFTs).

202A rig is a virtual skeleton that allows a model to move. It consists of a hierarchy of individual bones, much like a real life skeleton, and it works under a parent/child relationship. This document will cover some basic rigging concepts, such as bone position, bone orientation, deforming and non-deforming bones, the difference between IK and FK and their purposes. The structure of an avatar’s rig, custom attributes, and setup for animating can be found in rig features .

Armature Transforms # These are the armature’s transforms in Object Mode with the controls’ setup. Do not edit this in any way. The rig should only be manipulated in Pose Mode. To avoid unwanted editing, the transforms have been locked in Object Mode.
Rig 1.0 transforms.
Warning: Never edit the rig in Object Mode.
Bone Orientation # This is the bone orientation for Rig 1.0. As it is right now, it’s not possible to mirror behavior on the shoulders, arms, hands, or fingers.

In order to take your Decentraland Emotes to the next level you can add props (3d geometry) and/or sounds to them, doing the emotes much more fun and engaging! In this guideline you will find everything you need to know to export them correctly!
The Basics and Limitations # To start adding the props to your emotes it’s important to use the Decentraland Template File which will have the rig for the avatar and also the Ground Reference to keep your work inside the allowed space boundaries.

Emotes 2.0 can have sounds and props, but did you know it’s also possible to use particles? They can be a lot of fun and add that extra visual spark to it! And they can speed up the animation process too.
But since object animation and particle systems are not supported in Emotes 2.0, we need to convert these particles into an armature (which is supported) in order to add them to emotes.
