Package net.minecraft.client.render

Class LightmapTextureManager

java.lang.Object

net.minecraft.client.render.LightmapTextureManager

All Implemented Interfaces:

AutoCloseable

@Environment(CLIENT)
public class LightmapTextureManager
extends Object
implements AutoCloseable

The lightmap texture manager maintains a texture containing the RGBA overlay for each of the 16×16 sky and block light combinations.

Also contains some utilities to pack and unpack lightmap coordinates from sky and block light values, and some lightmap coordinates constants.
