Hi
For any Away3d question its very usefull to let us know, about what away3d version you are talking.
Since away3d 4 does not have any PhongPBMaterial, this question seams to be about away3d 3.6.
i think if you apply a white texture as normal-map, you do apply a normal effect to the fullest.
i am not 100% shure, but i think thats your problem.
I believe the normalMap thats is expected by the PhongPBMaterial should be in Object-Space, which afaik means you would have to use some 3D-software to calculate a normal-Map in object space, that does not have any effect on the surface.
If the PhongPBMaterial would use NormalMaps with TangentSpace, you could use a normalMap filled with this color: 8080ff
As i said, not 100% shure of that, but may be worth to look into.
Hope that helps.
