I keep getting this error at the end of the installation on my mac os 10.14.6.
Hi, it’s a known issue in the current ARCHICAD direct link.
We recommend continuing to work with the traditional export/import process until a fix is available.
Export an ARCHICAD project to FBX format and import it into Twinmotion. To go back and forth between ARCHICAD and Twinmotion, simply click on the “refresh” button above an imported file.
