Actor/Material broken on import

Hi, when importing this actor into ue4 from c4d a couple of glitches occur. I’ve tried several different import / export options and it only worsen’s the problem.

The polygon normals are facing the wrong way as a result the engine is backface culling and they are invisible. To fix the issue in C4D go to Options > Polygon Normals. Now you will be able to see pointy things which shows the way that polygon is facing . All polygons should face outward. If you want to check for the error in c4d then go to Options> backface culling and same problem effect should appear in c4d.

There is another option but that is a bad way of doing this, in the material properties, tick mark the “two sided” material option.
