It provides functions for altering the player’s appearance, primarily used in their own mods-but it’s also been adopted by other developers for similar purposes. Loaded on demand by: Create protection pixel mod – this means the API is only activated when required by that specific mod, helping optimize performance.

Features:
- Swap out player skins or apply partial textures to specific body parts without making the rest invisible.
- Adds entirely new models or layers to players and mobs, perfect for transforming appearances.
- Supports transparent textures and lets you hide the base model when applying new visuals.
- Ensures custom appearances are visible to all players in multiplayer environments.
- Modify entity size and hitboxes dynamically using built-in procedures.
