Features
- Supports vanilla block-editing commands such as
/setblock,/fill, and others - WorldEdit support for editing single-player worlds
- Axiom support for editing both single-player worlds and servers (see the Wiki for details)
- Litematica support for viewing and saving correct custom blocks
Additionally, to improve the user experience, the mod provides:
- When the server is running CraftEngine, disabling custom blocks in server and enabling cancelling block updates in the server on the client can resolve some visual issues
- Disables the resource pack loading screen
How to Use
- Make sure the client’s
server-side-blockscount is not lower than the server’sblock.serverside-blocksvalue - Launch the client and enable the custom blocks in server option in the mod menu
Notes
- Before editing a single-player world, you need to join a server at least once with custom blocks in server enabled to load the correct visual properties, otherwise block appearance may be incorrect
- If you build in single-player using this mod and later import the world to a server, you must enable
chunk-system.sync-custom-blocks-on-chunk-loadin the CraftEngine server configuration to ensure custom blocks are saved properly - Do not install other mods that register new blocks. Tools such as Axiom edit blocks using block state IDs, and mismatched registries between client and server can cause severe problems
- Ensure the client and server are running the same Minecraft version
