Jodkas Smooth Terrain

Smooth Terrain.      

Give Minecraft’s natural landscapes a smoother shape while keeping its familiar pixel textures and biome colours.

Smooth Terrain rounds hills, mountains and caves without replacing your world’s blocks. Customize the look in-game—from subtle rounding to more dramatic terrain.

Features

• Adjustable terrain rounding with an in-game strength slider.
• Original pixel textures and biome colours preserved.
• Better Grass-style sides for greener slopes.
• Optional leaf and log rounding, configurable separately.
• Smoothed snow and connected shorelines, with fixes for water and ice transitions.
• Block and tag blacklist to exclude specific materials from smoothing.
• Quick category filters for technical blocks, containers, fences, walls and panes.
• Press M to open the settings directly. The shortcut can be rebound in Minecraft’s controls.
• Mod Menu integration for convenient configuration.

Building materials, logs and leaves keep their original models by default. Natural materials such as raw stone can also appear in buildings; use the blacklist to protect those blocks.

Movement

Safe movement is enabled by default, preserving Minecraft’s normal player and animal collisions.

Optional experimental rounded player movement follows the smoothed terrain more closely. Recent fixes address singleplayer rubberbanding, uphill sticking and downhill ground contact while preserving jumping, obstacles and cliff falling.

At high rounding levels, safe-mode collision boxes can differ from the visible terrain.

Performance and compatibility

Recent optimizations reduce terrain-baking work, emitted vertices, temporary allocations and collision-calculation time. Actual performance depends on your hardware, settings, shaders and installed mods.

• Works with the Vanilla renderer.
• Supports Sodium, with tested Iris shader compatibility.
• Additional Sodium versions, shader packs and mod combinations have been playtested.
• Rounded movement has been tested in singleplayer with Vanilla and Sodium at 25%, 80% and 100% rounding.

Compatibility depends on the specific versions and configuration. Experimental rounded movement has not been verified in live multiplayer.

Requirements

• Minecraft Java 26.3
• Fabric Loader 0.19.5 or newer
• Java 25

Mod Menu is optional. Smooth Terrain does not require Fabric API or Cloth Config. Sodium, Iris and shader packs are installed separately.

Installation

1. Place the Smooth Terrain JAR in your mods folder.
2. Remove older Smooth Terrain JARs before updating.
3. Launch Minecraft and press M to customize your settings.

Existing settings are preserved when updating. Smoothing changes the terrain’s appearance; your saved block IDs and world grid remain unchanged.
