Please read this carefully before downloading.
We do not expect the program to corrupt any worlds but please back up any saves that you care about in the two Minecraft directories located at
Java -------- %AppData%/.minecraft
Bedrock ---- %LocalAppData%/Packages/Microsoft.MinecraftUWP_8wekyb3d8bbwe/LocalState/games/com.mojang/minecraftWorlds
We are working towards Amulet being a full 3D editor but we are not there yet. The program can now do basic fill and replace operations with changes saved to the input world. It can also be used as a world converter to convert one world into another.
The converter works by first specifying the input world. This is the data that will be converted to the output world.
Then you specify the output world, click convert and the input world will get merged into the output world replacing any chunks at those locations
As such do not select an output world that you care about as some of the chunks will get overwritten. If you really want to use a world you care about as the output, make a copy of it before converting.
The input world should remain unchanged but to be safe back this up as well.
When selecting worlds double check that the names at the bottom of the screen next to the convert button match up with the ones you selected.
There is currently a bug where the screen jumps a little causing a different world to be selected.
Conversion Process
Download and extract the zip file to somewhere on your computer. All of the files are required.
Run Amulet-Converter.exe
Make sure that all worlds are closed and Minecraft is either closed or on the main menu.
A black console should appear along with a user interface showing you worlds you can pick.
Click on the world you want to open (this is the input world) - See the description on worlds below.
The screen should change to the world view. (Note at the top of the screen there should be two tabs. One is the main menu and one is the name of the world)
Select the output world (the one that will get overwritten)
Click the convert button and wait for the loading bar to finish at which point a box will appear saying it has finished.
You can now either close the translator and open the world in game, select a new output world to convert the same input world again or go back to the menu to select a new input world.
Worlds
Amulet supports all vanilla worlds newer than (and including) Java 1.12 and Bedrock 1.7 and some older worlds may work as the input world.
The program supports conversion to and from any world format newer than those versions.
For example here are some conversions that are possible
