Data Table

Biome presets and parameters are stored in data tables. For more info visit Biome Presets.

Row Name

Biomes offer multiple presets, such as "Dense Forest", "Dead Forest", "Forest with Meadows", etc. Select the preset you want to use here.

Biome Quality

Defines the biome generation quality level. This setting influences foliage density, draw distance, WPO usage, shadowing behavior, and global illumination. High preset targets ~ 60–70 FPS on an RTX 4090 at 4K resolution with 50% Epic scalability. The Cinematic preset uses the same foliage density as High, but without mesh culling - Intended for cinematic rendering. The Lowest preset disables WPO.

Advanced

Runtime Generation

EXPERIMENTAL FEATURE. Forces all meshes to spawn at runtime instead of being stored in the level, significantly improving loading times.

Spawn Proxy And HLOD

Replicates HLOD behaviour when Runtime Generation is disabled and sends proxies to the HLOD spawner when Runtime Generation is enabled.

Seed

Affects generation outcome. Each seed produces a different biome layout.

Intersection

Intersect

Handles intersections with other biomes.

Biome Priority

Higher biome priority will replace biomes with lower priority when they overlap in case they both have Intersect enabled.

Spawn Options

Fill Landscape

Ignores spline bounds and generates the biome over the full landscape area.

Land

Large Vegetation

Trees, bushes, large plants etc.

Ground Cover

Grass, fallen leaves, dirt patches, branches, etc.
