# Welcome to Infinite Runner Engine 3D

### Update 12.0 <a href="#update-12-0" id="update-12-0"></a>

Create and configure your runner using the approved Unity Editor tools. Begin with [How to Start](https://denvzla-estudio.gitbook.io/infinite-runner-engine-3d/how-to-start), a numbered guide to scenes, your own prefabs, compatible characters, UI customization and protected Play Mode testing.

Open the tools through **Denvzla Estudio → 3D Infinity Runner Engine → Welcome Window**. Character Creator creates a compatible new prefab; the character's own D3Controller Inspector provides its six configuration tabs.
