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.

Testimonials
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.
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.
