Raven 5.1+ is an AAA-quality character resource pack designed for Unreal Engine 5, offering advanced customization, real-time performance, and game-ready features. Built with modern character workflows in mind, Raven provides thousands of visual variations, responsive physics simulations, and a fully featured overview level. The pack includes a fully rigged control system with support for ARKit morphs, integrated IK foot placement, and a procedural animation system that dynamically handles hair, clothing, and accessory physics. Users can easily switch between texture sets and enjoy deep material control across hair, clothing, skin, and gear. The character is rigorously rigged to Unreal Engine standards, featuring full IK and additional bones for cloth, hair, and accessory simulations. Compatible with Windwalker Echo, it supports both third-person and IK-free blueprint versions. Two level presets are included: a polished beauty render scene and an in-depth overview level showcasing all features. A bonus stylized weapon asset is provided, using the same master material system for seamless integration. The project features a clean, well-organized structure with proper folder hierarchy and naming conventions, ensuring full compatibility with Unreal Engine. Designed for ease of integration into existing projects, Raven balances flexibility and performance for both beginners and advanced users.
