World Machine (2025 Edition)

A node-based terrain creation tool specializing in geological simulation. The late 2025 build features 'Turbocharged' CPU threading, native support for tiled builds (up to hundreds of gigabytes of data), and advanced erosion algorithms like Thermal and Snow. While it offers the most granular control over geological logic, its reliance on CPU-heavy processing and a legacy UI have made GPU-accelerated tools like Gaea 2 the preferred choice for faster iteration.
