Importing Vectorworks model into Twinmotion

Hi all, I have a question regarding importing into Twinmotion from Vectorworks.

I have a Vectorworks Landmark 2024 model and I would like to import it into Twinmotion 2025.1.1. When I do this it generally work fine however, the following issues present:

  • A particular hardscape (planar pad with a slope) is always missing from the model.
  • Unless the site model has a texture bed or draped surface (landscape area / hardscape) no site model surface appears at all, only the skirts of the site model.

I found that if I import the exact same model from Vectorworks into Twinmotion 2023.1.2 the model imports just fine. If I then save it and open up Twinmotion 2025.1.1 and then select the .tm file from the 2023 version and open this up in Twinmotion 2025.1.1, following the conversion that takes place the Vectorworks model loads just fine.

Can anyone explain whats going on here?

If required/possible I can attach the Vectorworks file (.vwx) for reference along with the exported Cinema 4D file (.c4d)

Any help would be amazing, thank you!
