Additive Scene Groups

Set-based multi scene workflow

Features  

• Combine multiple scenes into a group to be loaded additively in Unity
• Auto-resolve scene groups that share the same scenes
• Editor tool:
  • Save scene groups in the editor and load them later with a click of a button
  • Sort through groups for quick access

Motivation  

When it comes to working solo on a project, it is very easy to dump every game object and prefab into one scene and just make it work. Sometimes you might need to add a new scene for a new level, but at any time in the game, there is generally one scene active. However, when working collaborately, having single scenes leads to problems:

• Multiple people working in parallel on the same scenes
• Some may be inexperienced and can mess up the entire scene by accident
• More time is spent resolving conflicts instead of working on the game

In an additive scene workflow, the monolithic scene can be split into multiple smaller scenes, each with a significant purpose. For example, a game can be composed of { Logic, UI, Environment } scenes, where each team member can work separately. At the end of the day, every scene can be loaded simultaneously to give the illusion of a singular scene.
