Biome Generator

The Biome Generator places biome-driven environment content such as forest volumes and filtered PCG generation. Use it after the base landscape setup is working, then tune density, filters, and placement rules for the world you are building.

Core Idea

The generator uses placed biome actors and generation settings to control what appears in the world. The setup can account for density, physical material filters, generation filters, and world-partition-friendly placement.

Use It When

• You want to populate a map with trees, vegetation, rocks, or other biome-specific environment content.
• You need a repeatable setup that can be tuned through data and component settings.
• You are working with a World Partition map and need biome content to behave cleanly in large worlds.

Recommended Workflow

1. Set up the landscape, material, and optional RVT workflow first.
2. Place the biome actor shown in the Getting Started guide.
3. Choose an appropriate generation setting, such as sparse or dense.
4. Use generation filters to avoid unwanted surfaces or material types.
5. Test in editor and in Play mode before scaling the setup across the full world.
