1.20.1 High Quality | Xray
Despite its reputation, Xray is not inherently evil. In creative-mode builds or on large-scale technical servers, the mod is repurposed as a diagnostic tool. Builders working on massive underground structures use Xray to locate and clear out hidden caves, ravines, or lava pockets that would otherwise disrupt a foundation. Redstone engineers use it to find slime chunks or to trace the path of underground waterways for transport systems. On single-player worlds or private creative servers, there is no victim; using Xray to plan a minecart tunnel or to find a specific geode is no different than using a mapping tool. The ethical boundary is clear: Xray becomes problematic only in competitive or communal survival contexts where resource scarcity is part of the social contract.
The fixation on “1.20.1” in the subject line is not accidental. This version, released in June 2023 as a hotfix to the Trails & Tales update, represents a high-water mark for mod compatibility. Major mod loaders like Fabric and Forge stabilized quickly on 1.20.1, and utility clients were among the first to update. Unlike later versions (1.20.4, 1.20.6) that introduced minor data-pack changes, 1.20.1 remains the “modding stable” release—meaning Xray tools for this version are mature, widely tested, and feature-complete. Furthermore, many large SMP servers deliberately pin themselves to 1.20.1 to ensure plugin stability, making this version the primary battleground for anti-cheat versus Xray developers. xray 1.20.1
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.
