In the Unreal Engine 5.7 “Range” demo, developer Dylan Browne uses Nanite foliage voxelization to render a sprawling 16K‑resolution landscape populated with over 200 trillion procedurally generated polygons—all running on an RTX 4090. The voxelized Nanite foliage system enables Unreal Engine to display ultra‑high detail scenes that previously would have crashed or slowed down traditional rendering pipelines.

This voxel technique, showcased in The Witcher 4 demo, transforms dense forests into manageable voxel assemblies, unlocking unprecedented scale while preserving visual fidelity. In editor mode, the scene can run at around 30 FPS. Browne’s experiment highlights how UE5‑Main (5.7) extends Nanite’s reach for massive environments, offering a new frontier for real‑time rendering and procedural vegetation workflows.
