4D Skin Geometry Loader Android – Lib4dskin for Custom Skin Pack Rendering on MCPE Bedrock

4D Skin Geometry Loader is a native library mod for Android Minecraft Pocket Edition that removes restrictions on custom skin geometry. By default, Bedrock only allows non-standard player geometry in marketplace-signed skin packs. This mod patches the skin loader at runtime to accept any custom geometry JSON and preserve cape data, making it possible to use unsigned custom skins with advanced geometry.

Features

• Patches the skin pack loader to accept custom geometry JSON from any source, not just official marketplace packs.
• Enables the cape field in skin pack format, allowing custom skins to include HD capes.
• Preserves custom geometry references in skins.json instead of stripping them during load.
• Compatible with LeviLaunchroid and Ambient Launcher as a drop-in mod module.
• Built with Android NDK r27d for Android 5.0 (API 21) and newer devices.
• Lightweight at 325 KB with binary patching applied in memory; does not modify APK files on disk.

Compatibility

Works with Minecraft PE 26.x and version 1.21. Requires Android 5.0 or newer.
