Now the OBJ exported by Sweet Home 3D can be imported into TW2019, but the direction is wrong and the glass material should be reset.
It takes a little time to reset.

If it is directly compatible with twinmotion format,
If SweetHome3D is imported into twinmotion and can be rendered directly,
That's a great thing.

The VR function of Twinmotion 2019 is very powerful, and the video rendering is very fast. And it should support ray-tracing rendering in the future. And it's free software.
