Hello. My Revit 2020 and Twinmotion 2022.2.3 live link not working.

Development Pipeline & Plugins

I updated my UE5 to 5.1 from 5.0.3 and Datasmith with it, both for 3ds Max and Revit. My Twinmotion was also automatically updated to 2022.2.3 from 2022.2.2 after the UE update. As it happens, the live-link that was perfectly working when using the Datasmith from TM 2022.2.2 now doesn't work. It just exports lights from Revit to TM, no geometries. I tried rolling back Datasmith to the July 12 release from the official Twinmotion website but for some reason, I get an installation error. What to do please? Thank you in advance.

Hello ,

Thank you for posting in the community regarding the compatibility of the 5.1 Datasmith exporter with Twinmotiion 2022.2.3. In order to keep working with Twinmotion 2022.2.3 you will need to keep using the Datasmith Exporter plugin 5.0.3. Here is the article to reference regarding this topic: https://twinmotionhelp.epicgames.com/s/article/Datasmith-Exporter-plugin-5-1-compatibility-with-Twinmotion

Hello Vincent. Thank you for getting back to me. I saw that the upload date of Datasmith exporter for Revit has been updated to Nov 16, a day after UE 5.1 was released to the public. So it was my hope that this version would be compatible with the 2022.2.3 release of Twinmotion. Unfortunately, I still get the same error message while trying to use it in Revit after the install, even after I followed the instructions on the links you provided. The error message that I got from Revit is attached below. RevitErrorMessageDatasmithExporter
