One PCG graph, whole biome

A single PCG graph places trees, roots, ivy, ground foliage, mushrooms and rock formations. Density, slope limits and undergrowth patches are all editable on the actor.

02 / 04

Spline tools carve paths and clearings

Three spline blueprints: carve a forest path, remove only trees, or clear all foliage inside the spline.

03 / 04

11 drag-and-drop assemblies

Hero dead-tree compositions, stone formations and a ground kit — drop them in by hand or feed them back into the PCG system.

04 / 04

Nanite + Lumen, fully lit

Nanite and Lumen throughout. Both World Partition demo maps ship fully lit — drop a camera in and render.
