Kap's Terrain Overhaul
by kaps_studio
Kap's Terrain Overhaul is a NeoForge world generation mod that raises the build height limit to 8,000 blocks and changes how terrain and villages generate.
What it does
The mod adjusts world parameters so terrain can reach a height limit of 8,000 blocks, far above the vanilla ceiling. Generation then produces floating islands, overlapping structures and rougher terrain, and villages appear more often across the larger landscape. Its author describes the release as an alpha build from a new modder, so some generation may be experimental.
Client and server are both required: the server and every player need the mod installed. It is published for NeoForge only, across 11 release versions 1.21.1 – 1.21.11, with 0.1 for 1.21.11 as the latest file. The license is All rights reserved, so the code is not open source. Distant Horizons is suggested for viewing high peaks at range, and FerriteCore with Sodium or Rubidium/Embeddium is suggested for memory and rendering.
Key features
8,000-block height limit
The terrain height ceiling is raised to 8,000 blocks, giving room for tall landforms and vertical builds.
Floating islands
Generation can place islands of terrain that hang in the air above the surface.
Overlapping structures
Some structures can be placed in the same space, so buildings sometimes intersect.
More frequent villages
Villages are spawned more often, so settlements are easier to find across the expanded landscape.

Use cases
Vertical exploration
Players who want to climb or build far above the normal limit can use the extended height range.
Large maps with settlements
Worlds with many villages across broad terrain suit the frequency change.
Who it’s for: Players and server owners who want taller terrain and denser settlements on NeoForge 1.21.x, and who accept an alpha build with experimental generation.
