Description

CustomSkinLoader

What's this?

CustomSkinLoader is a Minecraft mod that loads skins, capes, and elytra textures from online skin APIs or local files.

This branch is the Universal generation of MCCustomSkinLoader. It replaces the old edition-specific jars with one bootstrap artifact. The bootstrap jar prepares a runtime CustomSkinLoader-Common.jar, remaps it for the active Minecraft mapping namespace, and applies the required loader-specific class patches at runtime.

Supported Loaders

Forge Legacy and Forge ModLauncher
NeoForge
Fabric
Quilt-compatible Fabric Loader environments

Feature

Universal Runtime

One user-facing jar is used across supported loaders. The generated installable artifact is:

Bootstrap/build/libs/CustomSkinLoader_Universal-<version>.jar

Common/build/libs/Common-<version>.jar is the nested runtime payload and should not be installed directly.

Support Plenty of Skin Load APIs and Customizable Skin Load List

Supported skin loading APIs:

MojangAPI
CustomSkinAPI
CustomSkinAPIPlus
UniSkinAPI
ElyByAPI
Legacy

Supported special skin sites and profiles:

Glitchless
MinecraftCapes
OptiFineCape
Cloaks+
Wynntils compatible profile support

You can customize the skin load list and load textures from any compatible skin server. Skin server owners can also use ExtraList files to help users add their server.

HD Skins and Capes Support

CustomSkinLoader can load and process HD skins and capes. OptiFine cape textures are converted to the standard cape format when needed.

Profile Cache

Decreases repeated network requests.
Allows cached profiles to load when the network is unavailable.

Local Skin

Load skins without a skin server. With the default Legacy paths, place textures under:

.minecraft/CustomSkinLoader/LocalSkin/skins/<USERNAME>.png
.minecraft/CustomSkinLoader/LocalSkin/capes/<USERNAME>.png
.minecraft/CustomSkinLoader/LocalSkin/elytras/<USERNAME>.png

Extra List

Skin servers can provide ExtraList JSON files. Users can put them into .minecraft/CustomSkinLoader/ExtraList to add servers to the load list.

Transparent Texture Support

The render patches are designed to keep skin and cape transparency correct on supported versions.

Default Load List

Mojang (MojangAPI)
LittleSkin (CustomSkinAPI)
BlessingSkin (CustomSkinAPI)
ElyBy (ElyByAPI)
TLauncher (ElyByAPI)
Glitchless (ElyBy-compatible profile)
LocalSkin (Legacy)
MinecraftCapes
OptiFineCape
Cloaks+

If you want to add another skin server to the default list, please open an issue.

To Skin Server Owner

CustomSkinLoader is designed for loading textures from many server implementations. It is usually better to support one of CustomSkinLoader's APIs than to copy this mod's internal implementation. If you maintain a skin server, you can provide an ExtraList file or request inclusion in the default load list.
