SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

This Skill provides a comprehensive guide for building procedural content pipelines in Unreal Engine, covering the PCG framework, ProceduralMesh, instanced meshes, HISM, splines, runtime mesh, noise, terrain generation, and dungeon generation to accelerate development and ensure deterministic results across sessions.

Core Features & Use Cases

  • PCG Framework: Node-based, rule-driven world generation for terrains, dungeons, vegetation, and runtime mesh outputs.
  • Procedural Mesh & Instancing: Techniques for mesh generation, per-vertex data, and efficient placement using Instanced Static Mesh components (ISM/HISM).
  • Spline-driven Terrain: Road and river generation along splines with procedural variation and terrain integration.
  • Determinism & Physics: Guidance on seeds, deterministic seeding, and physics/collision handling for generated geometry. See references/pcg-node-reference.md for node types and references/procedural-mesh-patterns.md for mesh generation patterns. For physics on procedural geometry, see ue-physics-collision.

Quick Start

Configure a PCG-based workflow to generate dungeon layouts and terrain in Unreal Engine.

Frequently Asked Questions about ue-procedural-generation

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I set up procedural generation in Unreal Engine 5?▼

Procedural generation in Unreal Engine 5 is set up by configuring a PCG-based workflow that handles world layout and terrain creation. This uses the PCG framework with instanced meshes and splines to define rule-driven generation pipelines.

What is the best way to generate dungeon layouts using PCG in Unreal Engine?▼

The best way to generate dungeon layouts using PCG in Unreal Engine is through node-based, rule-driven generation pipelines. This approach allows for deterministic seed configuration to ensure reproducible dungeon results across sessions and builds.

How does deterministic seeding work for procedural meshes in Unreal Engine?▼

Deterministic seeding for procedural meshes ensures reproducible results across sessions and builds by applying consistent seeds within the PCG workflow. This maintains identical generation outputs and stable physics handling for generated geometry.

Can I use spline-driven systems for terrain generation in Unreal Engine?▼

Yes, you can use spline-driven systems for terrain generation in Unreal Engine to create roads and rivers. This technique integrates procedural variation along splines directly with the terrain for dynamic world building.

Does Unreal Engine PCG support runtime mesh construction with instanced geometry?▼

Unreal Engine PCG supports runtime mesh construction by utilizing ProceduralMesh and instanced geometry components like ISM and HISM. These techniques enable efficient per-vertex data handling and mesh placement during gameplay.

Why are my procedural generation results different across Unreal Engine sessions?▼

Procedural generation results differ across Unreal Engine sessions when deterministic seeds are not properly configured in the PCG pipeline. Ensuring consistent seed usage and physics handling guarantees reproducible outputs across builds.
