thanks for the info alphaflyte
I'm already using softening and hardening on the edges (invaluable to get a nice look before smoothing). But the mesh does not lead to a nice smoothing, even after some tweaking. I played about with the settings on the smoothing options and got a slightly better look but in the end thought it would be good enough to increase the mesh around the curves and not bother smoothing.
Thanks for the icons btw, I'll be adding them to the custom shelf - It'd be nice if people aggregated all the possible shelf icons into easy to download packs. Then a script with a simple association with the name of the action and an image in a folder could be really handy.
