public static void Clear ();

Description

Deletes all lightmap assets and makes all lights behave as if they weren't baked yet.

The assets are located in the folder with the same name as the scene. Only the assets with names matching the following pattern are deleted. The naming depends on the lightmap mode:

Non-directional lightmap mode:
Lightmap-#_comp_light.exr

Directional and Directional Specular lightmap mode:
Lightmap-#_comp_light.exr
Lightmap-#_comp_dir.exr

It will also clear the lightmaps array and clear lightmap indices on all objects.

Baked light probes and reflection probes are cleared as well.
