The API includes various default APIs to streamline cross-platform modular item development. Features include material stats with reference capabilities, usable GUI APIs, a default extendable Crafter GUI, complex module properties, and custom per-property resolving. It offers almost 100 default materials and dozens of default properties. Complex and extendable per-module rendering allows custom model types and extends 3D capabilities. Systems for synergies, property injections, and skins can add or modify module and item properties. Generative Materials automatically scans other mods' content to add materials, providing a bridge for compatibility.
