I originally replied to a thread in the Rendering forum, but reposting it here as a new topic in the hope that it gets more traction.
I'm encountering a bug when using the Datasmith Direct Link Synchronize tool (this button: ) with Vectorworks 2022 SP2.1 and Twinmotion 2022.1 (Windows 10 64-bit). Sometimes a few of the material overrides stick, but most of the time all the materials in my Twinmotion model revert to their original state when I send an update from Vectorworks.
