Hey everyone, I’m running into a really frustrating issue with Twinmotion 2025.2 and Archicad 28 using the latest Datasmith plugin.

My workflow is simple: I export a Datasmith file from Archicad and import it into Twinmotion. The first import works perfectly.

The problem happens when I close the Twinmotion file and come back to it later. If I’ve made changes in Archicad and try to update/reimport the Datasmith file, Twinmotion crashes immediately.

The only workaround I’ve found is to delete the Archicad Datasmith import in Twinmotion and re-import it from scratch, but that means reapplying all materials and textures, which is extremely time-consuming and frustrating.

Has anyone else run into this? Is there a trick or workflow to update a Datasmith file without losing everything?
