I tried for a while to do additional fillets and chamfers in fusion and viacad, but found the process time-consuming and cumbersome, when really all I wanted to do was round out the razer-sharp corners. I can think of very few things in real life that have razor sharp edges. And those sharp corners simply don't bake well to the normal map of lower-poly assets. A softened edge just looks better on a normal map. But if I'm going to be texturing in 3D-Coat anyway, and I can skip fusion of viacad, then I'll do it. :)

Just thinking outside the box here, but what if the meshing process in MOI allowed us to set a corner radius? :)
