I don't really know enough about it to troubleshoot from top of my head. But what kind of object is that? I didn't think with nurbs you use standard shaders. I can't really say how exactly it works, but I learned it from doing some tutorials on pluralsight. These days I am using advanced skeleton whenever i have to rig, so…
The picture is a NURBS sphere with a surface shader as a texture. All the tutorials I've found don't mention this problem, only how to make the controllers. It looks fine when the file opens but when you click on the sphere the shader breaks like in the picture.
