Quick Scoop

To add different skins to **Mirror World** in JJS, the common method players describe is to switch the skin tied to the mirror effect, usually by opening the skin option, selecting the grey/default skin slot, and then choosing a new saved skin image from your device or camera roll. One recent guide also points to a Roblox skin customization update, which suggests the feature may depend on the current game version and how the mirror ability is configured.

Basic steps

  1. Open JJS and get to the Mirror World setup or emote screen.
  2. Select the grey/default skin entry.
  3. Tap or click New Skin.
  4. Choose the skin image you already saved on your device.
  5. Confirm the skin type if the game asks for it.

What players are saying

A Reddit discussion shows that some players are still figuring out where custom avatars are made before they appear in Mirror World, so the exact process can depend on whether the skin is created inside JJS, saved locally, or imported from another editor. That means if the skin does not show up right away, the issue may be the source file or the in- game skin slot rather than Mirror World itself.

Possible limitations

  • Some versions or servers may not support custom skins the same way.
  • The skin image usually needs to be saved properly before the game can detect it.
  • If the option is missing, the feature may be tied to a specific update or gamepass setup.

In short

The simplest version is: save the skin image, open Mirror World’s skin selector, choose the default grey slot, and replace it with your saved skin. If that does not work, the most likely cause is that your version of JJS uses a different upload or avatar setup.

TL;DR: Pick the grey skin slot in Mirror World, hit New Skin, and load the saved image from your device.
