Origen is highly customizable through YAML configuration files. You can adjust everything from biome sizes and terrain height to river frequency and distribution presets.

​
Key Configuration Files

Origen’s customization system is organized into three main configuration files:

​
customization.yml

The primary customization file located at the root of the pack. This file contains most of the settings you’ll want to adjust, including:
  • Biome spread settings - Control biome sizes, jitter, and borders
  • Terrain parameters - Base Y level, height, ocean depth
  • River settings - River scale, width, and spacing
  • Elevation controls - Continental scale, elevation thresholds
  • Temperature and precipitation - Climate zone distribution
  • Special features - Sinkholes, canyons, spot biomes

​
pack.yml

Controls the core pack configuration, including:
  • Biome distribution presets - Choose between different world generation styles
  • Population stages - Define what features generate and in what order
  • Addons and dependencies - Required Terra addons

​
meta.yml

Contains global metadata and constants:
  • World Y levels - Top, bottom, ocean level, deepslate transitions
  • Bedrock configuration - Where bedrock layers generate
  • Palette base definitions - Shared palette configurations

​
Configuration Structure

Origen uses a well-organized directory structure to separate different aspects of world generation: 
source/
├── biomes/              # Biome definitions
├── biome-distribution/  # Where biomes generate
├── structures/          # Trees, boulders, features
├── features/            # How structures generate
├── palettes/            # Block compositions
├── math/                # Noise functions and samplers
└── */rearth/            # New Origen-specific content
Most of Origen’s unique biomes and features can be found in subdirectories named rearth/. This is where you’ll find the new content that sets Origen apart from the default Terra pack.

​
Quick Customization Examples

​
Making Biomes Larger

Increase the cellDistance value in customization.yml: 
biomeSpread:
  cellDistance: 500  # Default: 350

​
Adjusting Terrain Height

Modify terrain parameters in customization.yml: 
terrain-height: 150  # Default: 100
terrain-base-y-level: 70  # Default: 65

​
Changing River Frequency

Adjust river scale in customization.yml: 
biomeSpread:
  riverScale: 0.001  # Lower = bigger, more spaced rivers
Each directory in Origen contains a README file explaining its purpose and structure. When customizing Origen:
  1. Start with customization.yml for most common adjustments
  2. Check pack.yml to switch between distribution presets
  3. Explore individual biome configs in the biomes/ directory for biome-specific tweaks
  4. Refer to README files in each directory for detailed explanations
Before making extensive changes, create a backup of your configuration files. This makes it easy to revert if something doesn’t work as expected.
