If you have any problems or find any incompatibilities using this please do report them here. Previous problems with Optifine and water/connected textures appear to have been fixed so there is nothing known to cause trouble at the moment.

Using MultiMC

Modified original documentation from the Rift Wiki

1. Make a new instance in MultiMC with with the wanted version of Minecraft—in our case, Minecraft
2. Click —it should open the page of the instance.
3. Click .
4. Set uid to and name to .
5. Select the newly created component and click —this should open the file in a text editor.
6. Edit the JSON to look like the example below, then save the file.
7. Launch the instance from MultiMC.

The version that I selected for the example is the one provided alongside VoxelMap here

If the example doesn't fit the Rift version exactly, change the version. For example, replace all occurrences of with .

You can use the version page to check the file for errors—obvious mistakes will show up in the page as soon as you click the button.

If the JSON file doesn't open in a text editor, make sure your operating system is set up to open files in one first.

The fork of Forge Gradle 2 used for has been improved for so is now supported and is strongly encouraged to be used. Access transformers which would have otherwise silently failed will now explicitly crash so they can be fixed, which is helpful for updating. The locations of all found transformers can be found by running / with and looking immediately after where the access transformer task is applied. Further improvements can be suggested here.

Any suggestions for Rift itself can be made as issues here, or pull requested directly. Feel free to join the Discord server if you want to talk about stuff first or have any other questions.

Setting up

For a bare bones setup which is ready to be tinkered with, see the Rift MDK (download).

If you want to start from scratch, use this in favour of the Rift wiki's, otherwise the information provided there is still accurate.

Remember to change the and for the mod you're making before publishing.

Changes between Rift and

Obviously the obfuscated mappings have changed so any access transformers will need to be updated. There is the beginnings of a tool provided for automatically doing this here. The same tool can also be used for more easily adding access transformer entries as it can go straight from MCP name to matching Notch names.

There have also been a few API changes within Rift to account for changes made in Minecraft

• The deprecated has been removed in favour of using
• no longer expects a set of s but is a callback for registering them directly now is not an enum. It provides a utility method for this purpose.
• now provides the client instance directly to match providing

There's been many MCP method name changes too but most (if not all) are obvious enough to not need listing here.
