Problem with texture

Hi guys,
I modeled and painted this 3d model in Zbrush.
Imported in 3ds max and exported to Unity have this, don’t really understand why.
If the camera is close to the model it looks good but moving away the camera, the model has these scretches.
Here are some pictures.

Thanks, Paki.


In the texture unwrap there is a black background and the texture doesn’t completely fit to mesh.
