The Houdini Engine for UE 4 Version 2 plugin now lets you connect to a session of Houdini Engine running inside Houdini. The state of Houdini Engine can be viewed in Houdini while working with the plugin in UE4. Changes you make on either end, whether in UE4 via the plugin or in Houdini via its various interfaces, will be synchronized to allow both applications to make changes and see the same results.

NOTE: This lesson uses the UE4 V2 plug-in which is now in beta. 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\Plug-ins\Runtime directory.

    Hi Simon, is there an official documentation for the version 2 of the Houdini Engine for Unreal?

    • Siver 1 year ago  | 

      As the Version 2 is still in beta there is limited documentation at the moment.

    Hi, Simon! Thanks for the vid but any additional info would be really appreciated. In particular, how can I sync my current opened Houdini session with Unreal?

    • Siver 1 year ago  | 

      You can try opening in Houdini the session sync menu (shown in video at 1:04) . Once that menu is open start the connection. Make sure the Houdini engine is running/started in Unreal.
