GAIA: Modular Procedural World-Building Toolset

Gaia is an end-to-end procedural world-building toolset designed to bridge Houdini’s calculation pipelines directly into Unreal Engine 5's runtime environment. Built with strict performance governance at its core, the toolset enables rapid open-world generation while adhering to rigid multi-platform target constraints.

Core Engineering Features

- Houdini Engine Integration: Engineered modular Houdini Digital Assets (HDAs) that process landscape data layers and instantiate native Unreal geometry directly in-editor.
- Procedural Content Generation (PCG): Authored hierarchical UE5 PCG graphs for deterministic scattering of foliage and structural assets based on underlying landscape weightmaps.
- Pipeline Automation: Programmed custom Python, VEX, and C++ automated scripts to enforce rigorous content validation and eliminate broken layout dependencies.
