How to convert your old 256 height Minecraft levels from 1.0 or 1.1 to Minecraft 1.2

You may have tried to open your old 256-height minecraft levels generated from the various 256-hieght and higher mods in the Minecraft 1.2 only to find minecraft crashing instantly. You might have then, like me, tried to open up your precious level in the testing version of MCedit only to be greeted with a message telling you there is no information in the level. Don’t worry, Your level is safe!

The new level converter does not overwrite your original file; however, it does rename the file type. You will need to go into your saves folder or wherever your level data are stored and look for the level.dat_mcr file. Change this file back to level.dat to replace the new, messed up one. Now your level will work again in MCedit Testing again.

Bringing your old 256-height Minecraft level into 1.2

With your old level loaded with MCedit, export any structure you want, or the entire level as a schematic file. If you haven’t dealt with schematic files, make a selection and you should see an option to export on the left (differs with versions of MCedit.) More info on MCedit can be found in the minecraft forums.

You’ll now need MCedit r1000 to import the schematic file into a 1.2 generated level. If you import an entire level, any new terrain will be generated from the new 1.2 code. MCedit r1000 can be found here:

or find the link to this page from the MCedit page on the minecraft forum.

I’ve posted the links to the testing version of MCedit in my last post:

How to edit levels larger than 128 with MCEdit

TempleEdit: This post is for minecraft 1.1. MCedi tr1000 is what you need for minecraft 1.2. This 1.1 world generator mod is still useful as it generates epic landscapes that can be brought into minecraft 1.2. Check my newer post on how to bring your old 256-height levels into anvil format for 1.2.

I have recently become obsessed with the dessert biomes of minecraft. One of the things I’ve always wanted to do since I started minecraft, was to make a large sandstone temple. My heart sank every time I wish I could build something taller than 64 blocks high above the ground. Even after I found a height mod, I realized that the 256 height (bedrock to sky-limit) levels were not compatible with the standard editors MCedit and Word Edit. While it is fun to place every single block of large structures, editors help me get the project done faster so I can complete more of them and fix errors that would take days to correct without them. Fortunately, there is a version of MCedit which allows for editing large worlds.

Solving the height problem:

fishtaco567 released a height altering mod. You can download both client and server mod files from this link: http://www.minecraftforum.net/topic/544429-110100fishtacos-mods-better-caves-fps-height-mod/#height

Make sure you mod the server jar file and don’t try to modify the server exe file. Instructions on setting up jar servers are found on Notch’s minecraft.net site: http://www.minecraft.net/download

MCedit for higher than 128 height-limit levels:

Just click on the testing folder and download the file that goes with your operating system

Another way to get here is from the official forum page: http://www.minecraftforum.net/topic/13807-mcedit-minecraft-world-editor-compatible-with-mc-beta-18/

you’ll need to scroll down to quick links and click the old versions link.

You only have to design 1/8th of most symmetrical structures. With MCedit, you can clone your design and replicate it mirrored and rotated to make up the rest of your design.
