[away3d] Bitmap Smoothing

[vib]

Hi!

I'm using away3D 3.5

i was trying to apply PhongColorMaterial to a sphere but it doesn't
work.Other materials are working properly...

code snippet:    var colorMaterial:PhongColorMaterial = new
PhongColorMaterial(0x666666);
                        sphere = new Sphere({material:colorMaterial, radius:10, 
segmentsW:
10, segmentsH:10});
                        sphere.rotationX = 0;
                        sphere.rotationY = 0;
                        sphere.rotationZ = 0;
                        sphere.ownCanvas = true;
                        scene.addChild(sphere);

When I'm applying bit map to the 3d object its edges are getting
broken.I've also applied {smooth:true} in material. Is there any
solution ?
