There is no beveling involved in making this texture. What your seeing is an effect I used to do for making profiles and skins which is taking a copy of the lines, moving it 1 pixtal down and over. I wanted to see what it looked like and honestly it does not work well for this type of application as some of you already know.
Easy fix as I'll just turn that layer off and there is already a panel line shading layer, but does not show up well. Again, an easy fix. Another thing I do not like is how large the missile ports are and I wish this had a cockpit and the nose rounded some as it's too pointy for my taste.
Also, maybe it's me, but I get the feeling this ship is too small scale-wise as the Herk was always a big ship to begin with. I'll fiddle around with it when I get the time. Again as always thanks for the critique fellas.
