Lightmapping: Getting started

Preparing the Scene and baking the lightmaps

Select Window > Rendering > Lighting Settings from the Unity Editor menu to open the Lighting window. Make sure any Mesh you want to apply a light map to has proper UVs for lightmapping. The easiest way to do this is to open the Mesh import settings and enable the Generate Lightmap UVs setting.

Next, to control the resolution of the lightmaps, go to the Lightmapping Settings section and adjust the Lightmap Resolution value.

In order to be included in your lightmap, Renderers must meet the following criteria:

  • Have a Mesh Renderer or Terrain component
  • Be marked as Contribute GI
  • Use a built-in Unity Material, the Standard Shader, or a Shader with a Meta Pass

In the Mesh Renderer component, you can use the Scale In Lightmap parameter to adjust the resolution of your lightmap’s static Mesh or Terrain.

You can also adjust settings for Lights in the Light Explorer.

To generate lightmaps for your Scene:

  1. At the bottom of the Scene tab on the Lighting window, click Generate Lighting (or ensure that Auto Generate is ticked).

  2. A progress bar appears in Unity Editor’s status bar, in the bottom-right corner.

When lightmapping is complete, Unity’s Scene and Game views update automatically and you can view the resulting lightmaps in the Lighting window.

When you manually generate lighting, Unity adds Lighting Data Assets, baked lightmaps and Reflection Probes to the Assets folder.
