Open the door to powerful procedural workflows with Houdini Engine for UE4. Houdini’s node-based workflow makes it easy to publish networks of nodes as shareable Houdini Digital Assets. With the Houdini Engine, these assets can be loaded into the Unreal Editor with procedural controls available to artists.

These controls can be used to customize the look of the asset while the Houdini Engine works under the hood to "cook" the node networks and push the results back to UE4. This allows for deep integration of Houdini Digital Assets into an your game development pipeline. While not a runtime solution, Houdini Engine for UE4 provides a procedural content creation solution that makes it possible to build bigger worlds with more detail while working more efficiently.

Epic Games has committed $100 million to support game developers, enterprise professionals, media and entertainment creators, students, educators, and tool developers doing amazing things with Unreal Engine or enhancing open-source capabilities for the 3D graphics community.

SideFX is a two time recipient of MegaGrants with the funding going directly into the development of the Houdini Engine and Niagara plug-ins. The connection between Houdini and Unreal will continue to get stronger thanks to this initiative.


To access the Houdini Engine for UE4, download the latest Houdini installer which includes the UE4 plug-in. While the plug-in connects Unreal Engine to the Engine, a full Houdini install is needed to cook the results under the surface. 

With Houdini 18.5 there are two plug-ins downloaded - the original UE4 plug-in and the UE4 V2 plug-in which became production ready with build 18.5.462+. When you download and install Houdini 18.5 and choose to include the UE4 plug-ins, the old and the new plug-ins go into a directory under Houdini and you can then move it manually to the UE_4.25\Engine\Plugins\Runtime directory.


Install Houdini software and the Engine plug-ins onto your computer.


Houdini Engine
for Unreal 

Access FREE commercial licenses for use with the Unreal Plug-in.


Houdini Engine

Access up to three FREE licenses for limited commercial use in projects.


Houdini Engine licenses let you load assets into UE4 but do not give you access to the Houdini Core/FX GUI. 
The FREE Houdini Engine Indie license will let indie users open assets created in either Houdini Indie or Houdini Core/FX.

PLEASE NOTE: The Houdini Engine plug-ins do not work with the FREE Houdini Apprentice license and Assets created in the 
FREE Houdini Apprentice do not work with any of the Houdini Engine licenses.

In addition to the Houdini Engine plug-in outlined below, there are also plug-ins for the Unreal Niagara system and a Live Link plug-in which can be used to control rigs in Unreal directly from Houdini.

The Unreal Jam Starter Kit is a set of procedural game art tools that can be used in the Unreal game editor. This starter kit provides a variety of bread and butter tools that you can use right away to enhance your game environments. These tools each come with a tutorial and can be used inside UE4 using the Houdini Engine plug-in. 



To learn more about the Houdini Engine for UE4 plug-in, you can review the online documentation. This material covers many different aspects of the plug-in and how to set up geometry in Houdini to work effectively in the game editor. Learn about special attributes, instancing, landscapes and collisions amongst other valuable topics.


For a larger gamedev pipeline, you will want to learn how to create your own assets. In this lesson, you will learn how to create use some of the starter kit assets then how to create procedural assets in Houdini and publish them for use in UE4. You will also learn how to promote parameters to build a UI for the asset which show up in the Details panel in the Unreal Editor. This lesson will help you get comfortable working back and forth between Houdini and UE4.

Level designers can therefore use the Houdini Engine for UE4 plug-in to work with these tools without ever opening up Houdini's interface.


The Gamdev Learning Paths offer a number of games-focused lessons covering Houdini and the Houdini Engine. These lessons teach you how to create digital assets for use in host applications such as Unreal and are a great resource for game makers to learn how to go procedural.
