The Houdini Live Link plugin adds a new Live Link source that lets you controls rigs in Unreal directly from Houdini.
Installation ¶
The Houdini LiveLink plugin can be found in your Houdini install directory, next to the Houdini Engine plugin: HoudiniXX.Y\engine\unreal\5.Z\HoudiniLiveLink.
You can also download the plugin’s binaries from its Git repository in the Releases section.
After downloading the plugin’s release binaries, extract the archive and copy the HoudiniLiveLink folder to the Engine/Plugins/Animations folder in Unreal.
To turn on the Live Link plugin in Unreal:
-
In Unreal’s main toolbar, select Edit, then Plugins.
-
Locate the Animation tab.
-
Select the checkbox for Live Link and Houdini KineFX LiveLink.
-
Restart Unreal.
Compatibility ¶
Binaries and Source Code are available for Unreal 4.26.2, 4.27, and 5.0. The UE4_LiveLink HDA requires Houdini 19.5 or above since it uses KineFX.
Using LiveLink ¶
-
After installing the plugin, a new Houdini Live Link source will be available.
-
The LiveLink plugin should be used with the
ue4_livelinkHDA, available in the plugin’s content directory.
-
-
After importing the HDA in Houdini, start the LiveLink server directly on the live link node.
-
In Unreal, add a new Live Link source in Windows ▸ Live Link ▸ Add. The Houdini Live Link source will now be available and can be used as an animation controller.
