About this project
What does Biome brush add?
Biome Brush
The mod adds a simple tool — the Biome Brush, allowing you to change biome types on the fly with precise control over the affected area.

Biome Visualization
While holding the brush, biome colors are displayed in real time using particles above the terrain. Each biome gets its own automatically generated color, making it easier to distinguish neighboring biomes.

Controls
The brush is configured using the following commands:
- Biome — select the biome to apply
- Height — set the vertical height of the brush
- Shape — choose the brush shape: cube, sphere, or cylinder
- Size — set the horizontal radius
- Info — display current brush settings
- Undo — undo the last operation

Brush Interaction
- Right-click — apply the selected biome to the targeted area
- Shift + Right-click — copy the biome from the targeted location

Compatibility
Supports vanilla biomes, as well as biomes added by datapacks and other mods.
