Block Finder (X-Ray)
Every miner knows the feeling: you have spent an hour digging a branch mine, your inventory is full of cobblestone, and you still have not found the diamonds you were promised. Block Finder (X-Ray) exists to end that frustration. It is a client-side Minecraft mod that highlights the exact blocks you care about, drawing outlines that remain visible even through solid stone, so you can plan your tunnel instead of guessing where to dig.
What Block Finder (X-Ray) Actually Does
At its core, this is a block locator, not a full world renderer. Instead of stripping away terrain and exposing everything at once, it lets you build a personal watchlist of blocks and then scans the area around you for matches. Each tracked block type receives its own outline color, so diamond ore, ancient debris, chests, and spawners can all appear on screen at the same time without turning into visual noise.
The mod is available for Fabric and requires Fabric API, so make sure the correct API build is installed alongside it. Supported Minecraft versions track the modern Fabric release line, and the mod works in both singleplayer and multiplayer sessions, with the exception of certain Modrinth-specific builds. It also plays nicely with Iris shaders, though the author notes that shader-related quirks should be reported rather than assumed to be permanent.
How to Install Block Finder (X-Ray) for Minecraft
Installation follows the standard Fabric routine, and anyone who has added mods before will finish in under two minutes.
- Install a Fabric loader profile that matches your game version.
- Place the Fabric API jar and the Block Finder (X-Ray) jar into your mods folder.
- Launch Minecraft using the Fabric profile and confirm the mod appears in your mod list.
- Enter a world and press V to open the block finder menu. If nothing happens, check your keybinds and assign a free key.
If you would rather skip the manual file shuffling, the foxygame.net launcher handles it for you: it detects your installed Minecraft version and installs Block Finder (X-Ray) in a single click, keeping Fabric API aligned automatically. That same launcher also maintains a curated add-on catalog, so version compatibility is checked before anything touches your mods folder.
Using the Finder Menu
Press V to open the interface. Click the dropdown widget, type the name of the block you want, and select it from the searchable list. You can add as many block types as you like to the active pool. Clicking any entry in that pool opens a settings panel where you can adjust the scan radius around your player, pick a custom outline color, and set minimum and maximum Y-levels so the scan ignores the stone above your head or the bedrock below your feet.
The red X removes a block from the pool, while the Clear All button wipes the list entirely. The Submit button starts the scan. Auto Scan keeps results refreshed as you move, and the HUD toggle displays a live count of every block currently found. Load and Save buttons import or export your configuration as JSON, which is genuinely useful when you want to carry a diamond-hunting preset between worlds.
Performance and Practical Tips
Scans run on a separate thread, which keeps frame stuttering to a minimum even with a generous radius. Results update whenever blocks are broken or placed, so the outlines stay accurate while you mine. If the tracer lines appear to jitter, turn off View Bobbing under Options, then Accessibility Settings. Players running Wayland with Forge or NeoForge builds should launch the instance with X11 to avoid display glitches.
Used responsibly, Block Finder (X-Ray) for Minecraft is a huge quality-of-life upgrade for resource gathering, base building, and cave exploration. Grab the version that matches your loader, keep Fabric API current, and your next mining trip will be considerably shorter.
