Revit to Twinmotion through Datasmith - no objects displayed

Hello.

I use Revit 2023 and TM 2023.1.0.

I was trying to import Revit file through Datasmith; however, it always results with no objects visible. After sync, objects do appear in the scene manager, but not in the viewer (as if they were invisible). I tried to pick objects and zoom, check all the area - no result. I tried to change materials/facing - no result.

Considering that there were few similar topics opened before, and none have received the solution, I hope that an official TM developer support will answer this question.

I cannot attach the file because it's too large (urban-scale project).

I would also be grateful for any suggestion on this.

Thanks!

P.S. In the scene manager I see the folders, but not objects!

TO THOSE WHO ENCOUNTER SIMILAR PROBLEM, SOLUTION: If you have Revit 2023, please use DATASMITH 5.1! Datasmith 5.2 DOES NOT WORK with Revit 2023!
