Xray 1.20.1 Jun 2026

At its core, an Xray mod does not “see through” blocks in a magical sense. Instead, it exploits how the Minecraft client renders the world. In a standard game, the client receives chunk data from the server (or locally from the save file) and renders every visible face of every block within the player’s view distance. For performance reasons, the client already knows which blocks are solid and which are transparent. Xray modifications for version 1.20.1, such as the popular “Xray Ultimate” or utility clients like Meteor Client or Wurst, intercept this rendering pipeline. They selectively tell the client to skip drawing specific block types—most commonly, stone, dirt, gravel, and andesite—while forcing others, like diamond ore, ancient debris, or chests, to render as fully opaque, highlighted blocks. The result is a surreal, wireframe-like view of the underground where valuable resources appear suspended in a void. Notably, on a pure vanilla server without anti-cheat plugins, the server still sends all block data to the client, meaning Xray cannot be prevented server-side; it is a client-side illusion.
