Hello, when I put my tool in the scene, it freezes all of Unreal, I see the window at the bottom which displays "instantiation finish" but which is blocked. I looked for errors in the log but I found nothing. Do you have any idea where this could come from?

Please check to make sure the version of the plugin you are using corresponds to the Houdini build you are using. Then ensure the versions supports the Unreal version you are using. If Unreal is freezing, perhaps there is an issue with the way your HDA is authored.

Thank you very much, I checked and I have the same version 20.0.751 on unreal 5.4.4, and the tool I want to use works with the other members of my team

Please contact support@sidefx.com with your issue. State provide the above information and state if your members are using the same versions of both Houdini and Unreal. Additionally, please state if your machine specifications are the same as well.

Cheers,
Matt
