StraySkins

Overview

StraySkins is a skin management mod for offline-account setups: it lets offline-account players own and switch their own skins and capes just like premium players, and display them correctly to themselves and other players on multiplayer servers.

How to use

1. File naming: a file used for same-name auto-load must be named YourName.png (e.g. Steve.png; Chinese and any other characters are supported); other files can be named freely.
2. Apply an appearance: run /strayskins in game to load your own skin (and cape, if present), or use /strayskins skin <file> to pick a file; see "Command Preview" below for all commands.
3. Launcher: if your launcher already set a skin, it takes effect automatically on join; using the HMCL launcher to set your appearance and launch is recommended. Launcher-provided skins are a single static frame (see "Advanced Features" for animation).

Auto-load on join

• On a new player's first join, the mod tries in order and reports each step in chat: ① same-name skin/cape file → ② a random local appearance → ③ premium appearance from Mojang; only if all three fail is a failure shown.
• Players who have set an appearance have it automatically restored from their player/ folder on rejoin; if the files are missing, a hint is shown in chat.
• Fake players (FakePlayer) do not participate in first-join auto-load; set their appearance manually with /strayskins fake ....
• Supports single-player, LAN and dedicated servers.

Folder Structure

Put skin/cape images into the strayskins/ folder under the current game client's or server's root directory; files placed on the client are auto-uploaded on join, files placed on the server are visible to all players:

• skin/: skin library; skin commands and random skin pick files here
• cape/: cape library; cape commands and random cape pick files here
• player/: player appearance saves; one sub-folder per player (player/<player name>/) holding skin.png, cape.png and the save file <player name>.json; appearances are restored from here on rejoin
• player.txt: player name to UUID mapping (records historical players)
• fake/: fake-player-only appearance directory (separate from the real-player library); fake/skin/, fake/cape/ are the fake skin/cape libraries, fake/fake.txt is the fake name to UUID mapping

Advanced Features

• Transparency: use PNGs with an alpha channel; any opacity (including semi-transparency) blends correctly by alpha, for both skins and capes
• Ultra-HD: beyond the base sizes you can go larger (e.g. skins 512x512, 1024x1024; capes 512x256...); higher resolution looks sharper but uses more VRAM/RAM, choose as needed
• APNG animated skins/capes: keep the .png extension; plays in a loop at the image's own frame rate and is visible to all players. Animated images must be placed manually in the corresponding directory (strayskins/skin, strayskins/cape); a skin set through the launcher is a single static frame and cannot animate

Notes

• Must be installed on both client and server (with matching versions) for full display
• Commands can only be run by a player in game; the console / command blocks cannot use them
• Skin size: square, side a multiple of 64 (64x64, 128x128, 256x256...), or legacy 64x32 (no upscaled legacy); use PNG images
• Cape size: 2:1 landscape, width a multiple of 64 (64x32, 128x64...)
• When loading skin and cape together the skin governs: the skin must be valid, an invalid cape is simply skipped without affecting the skin; using the cape command alone does not require an existing skin (the default skin is used as the base)
• Skin/cape files must not exceed 20MB (larger files are rejected).
