Dimcreat

Dimcreat is a Fabric mod for Minecraft 1.21.11 that lets you create named custom dimensions from text seeds.

Use /gendim to generate a dimension, /gotodim to travel to it, and /getdimseed to check the stored seed later. Most seeds create fully custom generated worlds, while a set of exact seeds unlock special easter egg dimensions with their own terrain, atmosphere, and structures.

Features

• Create persistent named dimensions with /gendim <name> [seed]
• Leave the seed out and Dimcreat silently generates a random 20-character seed for you
• Travel to custom dimensions with /gotodim <name>
• Travel to vanilla dimensions with /gotodim overworld, /gotodim nether, and /gotodim the_end
• Check a generated dimension's stored seed with /getdimseed <name>
• Command suggestions for /gotodim and /getdimseed
• Exact-seed easter egg dimensions with custom terrain and structures
• Per-dimension time, weather, sky, particles, and visual behavior for supported seeds

Commands

/gendim <name> [seed]

Creates a new dimension.

• name is required
• seed is optional
• If seed is omitted, the mod generates a random 20-character seed internally
• Reserved names like overworld, nether, and the_end cannot be used
• Duplicate dimension names are rejected

/gotodim <name>

Teleports you to a generated dimension or a vanilla one.

• Supports generated dimension names
• Supports overworld, nether, and the_end
• Rejects travel if you are already in that dimension
• Rejects travel if the named dimension does not exist

/getdimseed <name>

Prints the stored seed for an existing generated dimension.
