Thanks for your reply. I said it was the latest, but I actually checked and the version I am using is also 27.2.0. Sorry for the misinformation. The versions are as follows archicad 27.2.0 twinmotion 2024.1 DATASMITH EXPORTER FOR ARCHICAD Compatible with Archicad 23 - 27 and Twinmotion 2023.1, 2023.2 and 2024.1 Repair and reinstallation did not help. Could this be related to the fact that twinmotion2024.1 in the library has a playtime of 0s?
