Highway created with C4D gets damaged by MED

Hey there,

I created a highway with C4D (SweepNurb) (pic 1) exported it into 3ds and imported it in MED.




In MED there already is that problem you can see in pic 2. I imported it from there as a mdl file into WED.

Do you have an idea how this problem can be solved?

Help is very much appreciated!
Thank you!

I think you have to reverse normals on track in C4D or in MED.

Hope I'm right.:)

Thanks for your answer. I did what you wrote.
But to reverse normals only works with MED.
When I save the mdl and load it into WED the problem occurs again.

Edit: I flipped them in C4D. It's working.

Thanks!
