Hi, to you all professionals!
My name is Markus and i am new here with a small problem.
I really love Datasmith, a dream comes true, cause now i can insert my models to UE4 without big problems.
But one thing is strange with one of my objects. When i import this telescope into UE4, the phong tag on the cubes are missing 
I dont know why but no matter how i export or convert it to ground object, everytime i get the same result. When creating a tube in the cinema 4d telescope scene and importing it with datasmith, it is showed normal, only the tubes for the telescope has these problems.
I tried changing the name of the tubes, creating new phong tag, etc., merg it (convert to ground object) Please help me.
Best Regards and thank you soo much from Germany, Markus
