Each dimension serves a distinct purpose and is designed to complement vanilla and modded gameplay with minimal overhead.
Palette Dimension
The Palette dimension is a builder's catalog and preview space. Using the /palette command with filtering (e.g., /palette oak, /palette stone), players can generate organized galleries of all registered blocks, filtered by material type and sorted by function. Blocks are displayed with proper orientation, connection logic, and special handling for doors, fences, gates, and other complex placements.
The dimension features a fullbright void sky with an indestructible floor, providing distraction-free block browsing. Players can clear and regenerate galleries on demand, making it ideal for builders planning large projects or modpack authors documenting available content.
Mining Dimension
The Mining dimension provides a dedicated space for resource extraction without permanently scarring the Overworld. Players can strip mine, quarry, and excavate freely, preserving Overworld aesthetics for building and exploration.
Access is provided via portals, allowing easy transition between mining operations and main world activities.
Sand World
Sand World is a resource-farming dimension containing only sand and terracotta biomes. It eliminates the need for extensive Overworld exploration when bulk quantities of these materials are required.
Portal access makes it convenient for large-scale building projects that demand thousands of sand or terracotta blocks without the tedium of desert searching or ocean draining.
Specter (Personal Dimension)
Specter is a personal pocket dimension consisting of a single chunk 128 blocks high. Each player has private access to their own instance, which unloads when they log off, reducing server load.
Access is granted via a special item, ensuring privacy and preventing unauthorized entry. Specter functions as a private workshop, storage space, or temporary build area—ideal for testing builds, organizing materials, or creating private infrastructure without claiming space in shared worlds
