Creating a Single Terrain

Opening a Scene

Open your Unity project and navigate to the desired scene where you want to create the terrain.

Creating a Single Terrain

Right-click in the Hierarchy window.
Select Create TerraForge 2 > TerraForge Terrain.

A new terrain will appear in your scene with a default TerrainData and TerraForgeTerrainGenerator component attached.

Configuring Terrain Parameters

In the Inspector window, locate the TerraForgeTerrainGenerator component.
Adjust parameters such as terrain size, resolution, noise settings, and erosion simulation parameters according to your preferences.

Setting Up TerrainPainter

Add the TerrainPainter component to the object via the Inspector.
Add the Terrain to the Painter:
- In the TerrainPainter component, click the "Add terrain from this object" button.
Enable Auto Repaint:
- Check the "Auto Repaint" option to ensure the terrain updates automatically whenever changes are made to the layers or settings.
Configure Layers or Load a Preset:
- To customize layers, manually adjust the settings in the Layers section of the TerrainPainter component.
- Alternatively, apply a preset from the preconfigured options by loading one from the following directory: Assets/TerraForge 2/Demo/Profiles/Terrain Painter LayerSettingsData Presets.

Generating the Terrain

Within the TerraForgeTerrainGenerator component window, click on Generate Terrain.
TerraForge 2 will procedurally generate the terrain based on your configured settings.

The video tutorial below shows a snippet of creating new terrains and genertion:

Creating a Grid of Terrains

Preparing Biomes

Biomes in TerraForge 2 play a crucial role in creating diverse and realistic terrains. Unlike traditional terrain generation methods that use static templates or pre-made stamps, TerraForge 2 employs biomes to define the procedural rules for terrain formation. Each biome encapsulates specific noise and erosion settings, which dictate the topographical features of the terrain, such as hills, valleys, mountains, and plains. When creating a grid of terrains, biomes ensure that each terrain cell can have distinct features, enhancing the visual diversity and realism of large terrain areas.
Select Create > TerraForge 2 > BiomeSettings to create a new biome settings file.
Configure biome settings such as noise and erosion settings. If you want, you can preview the biome settings and see how they affect the terrain.
You can also use the pre-configured biomes from the TerraForge 2 demo.

Creating a Terrain Grid

Open your scene or create a new scene where you want to place the terrain grid.
Right-click in the Hierarchy window.
Select Create TerraForge 2 > TerraForge Terrains Grid.
A new game object will appear in your scene with a default TerraForgeTerrainsGridGenerator component attached.

Assigning Biomes

In the Inspector window, locate the TerraForgeTerrainsGridGenerator component of the TerraForge Terrains Grid game object.
Ensure the Biomes array in the TerraForgeTerrainsGridGenerator is populated with the biomes you created earlier.

Generating the Terrain Grid

Within the TerraForgeTerrainsGridGenerator component window, configure grid generation parameters such as grid size, blending parameters, etc.
Click on Generate New Grid to initiate the generation process.
TerraForge 2 will procedurally generate a grid of terrains, with each terrain using randomly selected biomes from the assigned Biomes array.
Once the generation process is complete, you will have a new grid of terrains in your scene, seamlessly connected at the edges.

Setting Up TerrainPainter

Attach the TerrainPainter component to the object with the TerraForgeTerrainsGridGenerator component via the Inspector.
Add the Terrains to the Painter:
- In the TerrainPainter component, click the "Assign child terrains" button.
Enable Auto Repaint:
- Check the "Auto Repaint" option to ensure the terrains updates automatically whenever changes are made to the layers or settings.
Configure Layers or Load a Preset:
- To customize layers, manually adjust the settings in the Layers section of the TerrainPainter component.
- Alternatively, apply a preset from the preconfigured options by loading one from the following directory: Assets/TerraForge 2/Demo/Profiles/Terrain Painter LayerSettingsData Presets.
