Distant Biome

Spawn forests on distant mountain meshes

BP_DistantBiome lets you generate forests on top of mountain meshes included with your asset. It includes automatic culling that removes trees from surfaces facing away from the scene center, helping keep the performance cost close to zero.

Workflow

How To

Place the actor, choose a mountain shape, and spawn. Scaling and rotating the actor does not require manual tree adjustment.

01

Prepare the level

Create a regular level, preferably with a Landscape Actor.

02

Place the Distant Biome actor

Place BP_DistantBiome_(YourAssetName) in the level.

03

Choose a mountain shape

Select the mountain shape that best matches the environment you want to build.

04

Spawn and position it

Press Spawn to generate the forest. You can scale and rotate the actor; the trees adjust automatically.

Placement rule. Trees are spawned only on top of the selected mountain shape. They are excluded from other overlapping objects.

Culling

When culling is enabled, trees on mountain surfaces that face away from the scene center are removed automatically.

What changes. With culling enabled, trees are removed from surfaces facing away from the scene center. This reduces unnecessary distant geometry while preserving the visible forest.

Details Reference

The settings below mirror the BP_DistantBiome Details panel and control the selected mountain profile, forest coverage, and culling behavior.
