Advanced Scene Manager (ASM) is a scene manager for Unity projects that have grown beyond using Unity's basic SceneManager and LoadScene functionality.
Unity's built-in SceneManager and LoadScene methods work well for simple projects. However, as projects grow and require multiple scenes loaded together, persistent systems, loading screens, or consistent scene transitions, managing those relationships becomes more difficult.
Advanced Scene Manager provides a structured layer on top of Unity's scene system, helping you organize scenes into collections, manage additive scene loading, keep persistent scenes loaded, control project startup, and make scene changes predictable across your project.
Whether you are building menus, gameplay areas, loading screens, or large multi-scene projects, Advanced Scene Manager helps define how your scenes are organized and how they work together.

Advanced Scene Manager is designed for Unity developers working on projects where scenes need more structure than simple LoadScene calls.
Common examples:
- Projects with multiple gameplay scenes
- Games using additive scene loading
- Projects with shared managers or persistent systems
- Projects with complex startup requirements
- Teams maintaining larger Unity projects
- Scene Collections for organizing groups of scenes
- Additive scene management for projects using multiple scenes together
- Persistent Scenes for keeping selected scenes loaded
- Startup Scenes for defining how projects begin
- Loading Screens for handling scene changes with custom loading experiences
- Transitions for consistent scene changes
- Scene lifecycle handling for keeping scene logic organized
- Profiles for different scene configurations
- Addressables support for modern Unity projects
- Editor tools for inspecting and managing scene setups
Advanced Scene Manager builds on Unity's existing scene system rather than replacing it.
Scenes can be organized into Scene Collections, allowing multiple scenes to be grouped together and opened as a single setup.
Collections can contain gameplay scenes, UI scenes, managers, lighting scenes, or any other scenes that need to work together.
Advanced Scene Manager also supports persistent scenes, allowing selected scenes to remain loaded while other scenes are changed.
For projects using additive scene loading, Advanced Scene Manager provides a clearer way to manage relationships between scenes instead of relying on scattered loading scripts and project-specific solutions.

SceneManager.runtime.ToggleOpen(scene);
SceneManager.runtime.Open(collection);
SceneManager.runtime.Close(collection);
SceneManager.runtime.ToggleOpen(collection);
}
}Scenes and collections can also be opened through UnityEvents, such as from a Button.
The SceneHelper can also make it easier to find and reference scenes or collections from the Unity editor.
