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.
Right now, the only reason I’m still using Twinmotion is my custom library. Otherwise, I’d have switched to D5 Render already.
Has anyone else run into this? Is there a trick or workflow to update a Datasmith file without losing everything?
