Twinmotion will be a paid-for product in November 2019. Until then, download it for free as an early adopter and keep it for free forever.

Here with an old SKP! (so any Moi3D file can work except Nurbs of course!)
If you want Bim (for free Briscad Shape or PConPlanner)ArchiCad Revit just load a plugin!
