Welcome to Mutable! Mutable is a middleware to create character customization systems for games and other applications using Unreal Engine 4. At development time you can create objects and decide how they can be modified inside your project. Then Mutable builds instances of these objects at runtime based on options selected by the user or by your application. With Mutable you can clip and merge meshes, morph them, change texture colours, project images, and more. Mutable focuses on building these objects at runtime at the maximum performance, while giving your artists all the flexibility they need. This middleware is built from the experience of developing character customisation systems for games like PUBG (PlayerUnknown's BattleGrounds), KUF2 (Kingdom Under Fire 2), or All Points Bulletin Reloaded (APB).
