Stratum

Stratum is a dimension-stacking mod that merge independent dimmensions into a single, seamless vertical stack. Dig straight through the bedrock of the Overworld to drop directly into the ceilings of the Nether. No portals or loading screens required. It is made for mods like Create: Aeronautics and was built for the Create: Above the Clouds modpack.

• Seamless Stacking: Connects multiple dimensions vertically into a single world, removing loading screens and portal transitions when moving between height levels.
• Height Zone Isolation: Restricts dimension-specific mechanics, surface rules, and generation parameters to distinct, non-overlapping coordinate ranges.
• Sandboxed Worldgen: Coordinates the placement of biomes, carvers, structures, and features so they generate exclusively within their assigned vertical layer bounds.
• Data-Driven Configuration: Uses standard datapack files to define custom layer heights, stacking orders, and dimension configurations.
