I'm running Twinmotion 2023.1.1 with the most recent Datasmith plugins dated Madownloaded from here: I'm running AC 26 USA Build 5003 on macOS Ventura 13.4 on an Apple Silicon M2 machine running the Apple Silicon version of Archicad. The OS, version of TwinMotion, version of your Datasmith plug-in, Intel vs Apple Silicon etc all matter for someone to reproduce and either confirm the issue or work with you to resolve it. To the OP and recent posters - you really need to include in your posts all of your software details - or include it in your signature as you can see several of us here doing. This is an old thread, but has a new and new-ish replies.
