PCG Graph | Procedural Content Generation

PCG Graph brings node-based procedural generation to Unity with an intuitive visual editor. Create everything from scattered forest environments, roads, and bridges to precisely stacked library shelves — and grow procedural, surface-aware ivy that crawls walls, branches, droops across gaps, and sprouts leaves — using a flexible, extensible system.

Key Features:

Visual Graph Editor — Drag-and-drop node connections with real-time preview and debugging 

Flexible Generators — Area-based point distribution, Bezier curve paths, grid layouts, and Poisson disk sampling 

Object Placement — Weighted random selection, surface alignment, collision avoidance, and vertical stacking 

Procedural Ivy & Foliage — Grow surface-aware ivy (main stem, branches, hanging tendrils, corkscrew wraps) that adapts to any geometry, then scatter leaves with seasonal color, phyllotaxy, and distance LOD. GPU wind & snow via a Weather Zone (URP)

Mesh Generation — Sweep profiles along curves and paths into tubes, pipes, rails, ropes, and vines 

Transform Controls — Position, rotation, and scale with randomization and constraints 

Extensible Architecture — Create custom nodes to extend functionality

Built for Performance:

Burst-compiled jobs for fast point generation Native collections for memory efficiency Combined-mesh output with distance LOD for vines and leaves Editor and runtime support

Easy Integration:

Works with existing prefabs and materials Non-destructive workflow with undo support Deterministic seeding for reproducible results
