Lightmap Texture Viewer / Dumper
Lightmap Texture Viewer / Dumper is a Fabric utility that opens the game's lightmap and block and item texture atlases in a debug screen.
What it does
Once enabled, the mod shows the lightmap, the lighting texture the game uses for brightness, and the item atlas, which holds the textures of items as they are rendered in the GUI. A player can dump either one to disk, and the debug command can switch each viewer on or off. The atlas screen can be resized, and it shows only items as they appear in inventories rather than the full block atlas.
The mod runs on the client alone, so a server does not need it and players joining a server do not have to install it. It is released under the Creative Commons Attribution Non Commercial 4.0 license and is not open source. Files cover 1.21.7 – 1.21.11 on Fabric, with snapshot builds also published.
