Twinmotion features direct one-click synchronization of geometry and BIM information from your Archicad, Revit, Rhino (including Grasshopper), RIKCAD, or SketchUp Pro model. You can also export .udatasmith files from 3ds Max, which can be imported into Twinmotion.
Download the appropriate plugin and install it in your source application. Datasmith Exporter plugins are also used for Unreal Engine; if you have already installed the latest plugin from the Unreal Engine page, there's no need to reinstall for Twinmotion.
For an introduction on how to use the Direct Link feature of the Datasmith plugins with Twinmotion, see this
tutorial, which uses Revit as an example.
