Aloha,
Been playing with shaders and combining stuff a lot lately so I thought it time
to find out how to fix or work around this one - see this image:
http://colorshopvfx.dk/XSI/anisotropic_edge.jpg
Now I saw a technique the other day involving an incidence node to get rid of
the hard edge in the specular on the border between diffuse and ambient, but it
should hardly be a matter for techniques, rather something basic in the way the
material shader handles speculars, no!?
So if someone has a more direct approach to solve it I'd be happy to hear it.
Best regards
