Short summary

Multiple convai characters does not seems to work out of the box

What happened?

Cannot acquire connection — another component already owns the active connection for character [1be83aa8-0987-11f0-a880-42010a7be01a]. Make sure the previous owner calls ReturnSessionProxy before a new component tries to acquire.

The Convai Unreal Engine V4 plugin does not currently support multiple characters in a single scene.

There are already similar posts about this topic on the forum, so you may want to review those as well for additional context and faster answers.

Support for this workflow is planned for future updates, but I cannot share an ETA at the moment.

Thank you for the answer. Could you let us know which version of Convai plugin best to use that is compatible with unreal 5.8 but still supports multiple characters in the scene?

Kind Regards

There is no version available for Unreal Engine 5.8, but there is a version available for Unreal Engine 5.7 here:

The older V3 plugin supports this workflow, but please note that it does not include the latest features or updates.
