Minecraft X-Ray lets you fly around, over and under your world. The particularly useful feature is that you can use the function keys to specify certain block types to highlight. Unfortunately, MCEdit seems to be the only full featured map editor for Linux that supports the current map format (McRegion). Omen is a map editor for indev. It can import images, interact with maps on both a 2D and 3D level, change environment settings, and can convert maps to and from multiplayer format maps.
NBTExplorer is a low-level graphical NBT data editor originally based on. The key difference is NBTExplorer's full support for Minecraft.mcr/.mca region files, a directory-tree interface for easily exploring multiple worlds, and support for the latest NBT standard. NBTExplorer is built on top of. NBTExplorer can read: • Standard NBT files (e.g. Level.dat) • Schematic files • Uncompressed NBT files (e.g. Idcounts.dat) • Minecraft region files (*.mcr) • Minecraft anvil files (*.mca) • Cubic Chunks region files The NBTExplorer zip and installer packages for Windows now include a second utility, NBTUtil.exe, for command-line control of NBT data.
NBTUtil currently has a limited featureset compared to NBTExplorer. Windows Users NBTExplorer is a Windows.NET application, and requires.NET framework 2.0 or higher to run. Note: If you run Windows 8 or later, you may get a SmartScreen warning when first running the program. See the related FAQ entry for more information. Linux Users NBTExplorer has been tested for compatibility with recent Mono runtimes.
Minimally, your system needs the mono-core and mono-winforms packages, or whatever set of packages is equivalent. Mac Users A Mac-specific version of NBTExplorer is available with a native UX.
It is compatible with Mac OS X 10.7 or higher. It will not run on 10.6, sorry.
As of August 22, 2013, I've begun signing NBTExplorer with an Apple Developer ID certificate. If you have GateKeeper configured to only allow software from the App Store, then you will need to change GateKeeper to allow running signed downloaded applications, or following these instructions to bypass GateKeeper.
For older unsigned versions of NBTExplorer, you may also receive a cryptic 'OSStatus error -67053' if you try to bypass GateKeeper the normal way by right-clicking the app and selecting 'Open'. Here are some instructions to bypass GateKeeper for NBTExplorer: • Download NBTExplorer • Copy the NBTExplorer.app out of the zip, to your /Applications folder • Open your Terminal, found in /Applications/Utilities • At the prompt the Terminal gives you, type exactly the following: ', courier, monospace'>xattr -rd com.apple.quarantine /Applications/NBTExplorer.app This will clear the quarantine attributes that prevent NBTExplorer from running. If you have problems with the native client or you're running OS X 10.6 or older, you can still run the Windows version of NBTExplorer on your Mac by following the Linux instructions and installing the Mono runtime. You may still need to disable GateKeeper quarantine on the downloaded files.

Frequently Asked Questions Q: NBTExplorer didn't save my changes -- why? A: It's possible you forgot to save.
The more likely answer is NBTExplorer did save your changes, and if you were to immediately re-open your world in NBTExplorer, you would see that your changes are still there. Instead, Minecraft erased or ignored your changes when you loaded your world.
The most common trap is editing player settings or inventory on a single-player world and making your changes in a.dat file instead of in level.dat. Minecraft will overwrite your.dat file on load with the contents of the player tag in level.dat. Q: I'm on Windows and NBTExplorer crashed on start / didn't run. A: Did you get a message box listing one or more exceptions?
Reply to this thread with the information so you can be better helped. If you didn't get any message box though, or you only received a standard 'program has stopped working' message box, then you have deeper issues with your.NET environment. Do any other.NET programs run on your computer?
If yes, then try deleting the NBTExplorer.exe.config file that was installed / came with the zip. This will cause NBTExplorer to prefer the.NET 2.x/3.x framework over the 4.x framework, and may allow the program to run if your.NET 4.x framework is toast. You should still do something about that, of course. Q: I'm on Windows and NBTExplorer crashed with a scary warning. A: Windows 8 and later includes a program filter called 'SmartScreen' that prevents unrecognized software from running.
Its warning looks something like this: If you see this screen, press the 'More info' link to get a 'Run Anyway' button. This will launch the program, and you shouldn't see the warning again unless you update NBTExplorer. NBTExplorer is SAFE and has an established reputation in the Minecraft community. However, you don't need to take my word at face-value. The source code is publicly available for inspection, and you can download and build your own copy if you so wish.
