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).
The most important starting point to learn about mutable is the documentation Table of Contents.

Mutable Populations is a Mutable plug-in to automatically generate crowds or populations in Unreal Engine.
Create random variations to add content procedurally. Define what is a valid output for different populations to create cohesive outputs that communicate a common origin or culture. Assign each new asset some tags so it pops up automatically on new instances made by existing populations.
The Mutable Population plugin extends and requires Mutable Plugin.
