TFC Mantle Mountains Mod (1.21.1, 1.20.1) – Scale Gigantic Peaks

TFC Mantle Mountains Mod expands mountain sizes in TerraFirmaCraft to make natural terrain taller and wider. This mod scales up existing mountain biomes without increasing their spawn count across the world. It raises the maximum world height to 1024 blocks so massive peaks have enough room to rise. You can adjust the vertical and horizontal scale through a config file to match your preferred world look.

Features:

• Increases the vertical and horizontal scale of TerraFirmaCraft mountain generation.
• Raises the world height limit to 1024 blocks to accommodate towering peaks.
• Keeps natural mountain rarity intact without adding extra mountain biomes.
• Provides a setting to generate snow on all mountain peaks regardless of local climate.
• Lets you customize scaling numbers through the configuration file.

Configuration:

• Vertical scale: controls peak height (values above 4.0 look unusual, and values over 6.0 clip into the height limit).
• Horizontal scale: controls the width and slope spread of mountain ridges.
• Snow-capped peaks: forces snow generation on top of every mountain (disabled by default).

How to Use:

1. Find a mountain biome in your world using /locate biome tfc:mountains.
2. Check the terrain shape and save your world seed.
3. Edit the config values to adjust the width and height of the peaks.
4. Keep the vertical scale setting below 6.0 to prevent terrain from getting cut off at the world ceiling.
