Had another crack at Marvelous Designer tonight. I'm sure someone who knows what they're doing could match the cape concept perfectly just in MD, but as it is I'm happy taking this as my base to continue sculpting on in ZB.
@Monophobe : Great Idea to use Marvelous, you've got a great base to sculpt. I might give it a try too, i've used it once and it was a great tool. @AnotherDustin : Thanks ! Can't wait to finish the anatomy, i gotta start the armor pretty soon.
Decided to give Marvelous Designer a crack tonight. Not decided yet if I'll stick with my original cape sculpt and work it up or try and get something nicer out of MD, but I'm seriously impressed with it so far. Gets a bit mesmerising just moving it about during the simulation.
