I get no source found message in Twinmotion, and no connection in ArchiCAD. So i thought i'd try to export the Twinmotion file. When i import into Twinmotion only the lights show up. In ArchiCAD i opened the Datasmith Messages and there is a large list of errors. Not sure what's happening. Any help would be appreciated.
The 5.1 version of the plugin actually isn't compatible with Twinmotion yet, since it uses Unreal Engine 5.1 features and Twinmotion is only on UE 5.0.3, and that explains why those issues were occurring.
We'll be updating to UE 5.1 soon, so that plugin should be usable then. We'll update our plugin pages once that update becomes available.
