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.

1. Download the Houdini Engine

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. After installing the plug-in you will be prompted to get a trial license when you first load a Houdini Digital Asset into UE4.
