If you load multiple scenes simultaneously in your project, for example if you load multiples scenesA Scene contains the environments and menus of your game. Think of each unique Scene file as a unique level. In each Scene, you place your environments, obstacles, and decorations, essentially designing and building your game in pieces. More info
See in Glossary at the same time in an open world game, you can add the scenes to a single Baking Set so you can bake the lighting for all the scenes together.
Refer to Understanding probe volumes for more information about Baking Sets.
To place multiple scenes in a single Baking Set and bake them together, follow these steps:
You can only add each scene to a single Baking Set.
To remove a scene from a Baking Set, select the scene in the Scenes in Baking Set list, then select the Remove (-) button.
Select Generate Lighting to bake the lighting in all the scenes in a baking set.
The Universal Render PipelineA series of operations that take the contents of a Scene, and displays them on a screen. Unity lets you choose from pre-built render pipelines, or write your own. More info
See in Glossary (URP) uses the settings from the Baking Set, and serializes the results in the Assets
folder, in a subfolder with the same name as the active scene. You can move or rename the folder.
For faster iteration times, disable Bake next to a scene name. This stops Unity baking lighting data for this scene. This might result in incomplete data, but it can help reduce baking time when you’re iterating on parts of a large world.
Unity doesn’t automatically load the scenes in a Baking Set when you select the scene in the Scenes list. To load a scene, select Load Baking Set.
When you load multiple scenes together, the lighting might be too bright because URP combines light from all the scenes. Refer to Set up multiple Scenes for more information on loading and unloading Scenes.
You can load multiple scenes together only if they belong to the same Baking Set.
