Twinmotion to Unreal Engine 5.5 not working properly

Hi;

I’m trying to import my TM project in to UE 5.5. using the datasmith workflow. I’m aware that there are no specific plugins for that anymore but I need to enable the datasmith importer plugin in UE 5.5. But still I only can get external models, not the TM content. No vegetation, no weather, no fog, no vehicles, no hdri, nothing. It just looks like I’ve imported some external .fbx directly to UE 5.5.

I’m not an expert but I checked some tutorials etc. and seems something is off. Probably I’m missing something so simple to be mentioned in those tutorials. I don’t know.

I’ll be glad if someone can guide me through this. Thank you in advance.
