I have experiencing different rhino geometrys and here’s what I got.

Twinmotion Result:
It appears that Twinmotion doesn’t understand NURBs (closed solid polysurface) with different materials.
When I exploded the solid polysurface closed, only the surfaces that used the default material for that polysurface continued to appear. Surfaces that had other materials are gone. And yes, they have their normals facing the camera (I even put the materials in twinmotion as two sided materials).
Considering that I created test surfaces and applied the materials and twinmotion read them, the problem is not with reading surfaces, but with Nurbs with multiple materials.
Now the question is: how do people who use twinmotion survive?
