Skin

What it does

/skin gamertag shows that player's skin, rendered by MinecraftRender. The player doesn't need to be online, or to have played in your world: any Xbox gamertag works. Leave the player out to mean yourself, once you've linked your account. The answer is shown to everyone in the channel.

Your Minecraft world does no work for it: Discord loads the picture from minecraftrender.com.

Choose who may use it on the world's Permissions tab. At first, only Discord administrators can.

What it needs

BedrockRelay pack v0.4.0 on a dedicated server. It works on Realms.
