The Mutable Sample Project is now available to download for free on Fab!

Released in Unreal Engine 5.5, Mutable is a new character customization system. It enables game developers to generate dynamic skeletal meshes, materials, and textures for characters at runtime—all while optimizing memory usage, keeping shader cost low, and reducing the draw call count.

While Mutable is primarily used for creating character customization systems, you can also use it to produce all kinds of dynamic content—think customizable weapons, vehicles, and beyond.

Check out the sample to explore these features:

• Character customization: Enable players to customize character clothing, hair, make-up, tattoos, stickers, and more.
• Weapon customization: Build a weapons system that enables players to switch parts, change colors, add stickers, and choose patterns. 
• Showcase level: Explore the sample project’s example level that showcases Mutable’s features in an interactive way.
• Infinite level: Create a random crowd of customized characters in real time and measure the scene’s performance.
