Archicad Datasmith Direct Link


When I click the Datasmith Live Link button in Archicad (24) the popup dialogue suggests Datasmith direct link suggests a link is possible with Unreal as well as Twinmotion:

“Waiting for Datasmith Link connections to be established. Please start an application supporting Datasmith Direct LInk such as Twinmotion or Unreal Engine.”

This works fine for Twinmotion, i cant establish for Unreal. Can anybody shed some light on how to get this working? Is there an alternate workflow enabling updatining of cad model in platform then passing changes to Unreal?

Has anybody got something similar wokring for UE5?

Thank you.
