Presenting the Massive Worlds Toolkit

By popular demand of both Patrons and Clients, 

Presenting a Houdini centric Framework for massive open world generation in Unreal Engine 5.1.

Providing a new and powerful pipeline for open world building, the “Massive Worlds” toolkit empowers you to use your Houdini Digital Assets with Unreal, at a scale that simply wasn’t possible before.

With this toolkit you will be able to create, manage and operate a Houdini based Streaming Proxy Landscape pipeline in Unreal 5.1. It is based on nearly a decade of experience crafting massive open worlds for video games and employs some of the best practices I know.

Leveraging new Unreal 5.1 features, such as Landscape Edit Layers, this set of Houdini nodes will empower your pipeline, allowing you to procedurally shape your worlds in the Unreal Engine like never before.

Benefits

  • A new Houdini Centric Pipeline for Open World Construction & Data management
  • A Bi-Directional, Non-Destructive Pipeline between Unreal and Houdini
  • Externalized Data for Houdini
  • Manageable Memory Requirements when Loading Terrain Data for tools
  • Fast, Versatile, Procedural!

Featured Assets

Extract Unreal Landscape
This tool extracts the Unreal Streaming Proxy based Landscape to a Cache file for other MW tools to use.
Process And Export Tiles
The Core asset of the toolset. The PNET node allows Houdini to Import, Composite and Export Streaming Proxy tiles to and from Unreal with minimal data loss.
Load Layers
This utility asset loads on demand the Layer information stored in the Tile Cache. Can both transfer data to input geometry and output Heightmaps on demand.
Path Editor
A recursive pathfinding tool, that allows you to interactively draw roads on large terrains to create complex, realistically winding networks of roads.

  • Advanced, User Friendly Heightmap and Material Stamping nodes that integrate directly with Houdini’s Heightfield Workflow
  • A Bi-directional, Lossless Pipeline between Houdini & Unreal with full Edit Layer and Material Layer Support
  • Realistic slope sensitive Pathfinding Algorithm for Road Building
  • A highly interactive road editor, that is both Houdini and Unreal Compatible

Future planned improvements:    

  • Advanced Road Post-Processing
  • Tile based Instance Management
  • Tunnel and Bridge Tools
  • Procedural Terrain Stamps
  • General improvements throughout the Toolkit

Testimonials

I had the honor of being able to test the Massive Worlds toolset.

After few minutes I was able to understand how each asset worked and where each one fit in the pipeline, but I also understood the potential of this toolset.

It is not a simple toolset that allows you to exceed the size limit of the terrains in unreal, but it is a complete overhaul on how terrains of this magnitude are generated. It allows you to have a solid foundation on which to start developing your tools, expand your landscape, iterate quickly, and overcome limitations we had before.

Now the limit is what your computer's memory can support.
Oscar MateosHoudini Technical Artist at Fracture Labs
Mr. Erwin Heyms was of incredible help to us in order to understand the landscape workflow from Houdini into Unreal Engine and his tools were essential for this task.

He is one of the most dedicated persons I've seen when it comes to mentoring and it is noticeable that he loves what he does. I hope to work with him again in the future.

We'd definitely recommend his services.
