I probably wont do too much more today, or for a couple of days at that. Ive just spent some time looking at using some alphas to add some detail. Ive never used the layers in zbrush to control detail, but it's really easy and helps alot. That together with storing a morph target to give you the ability to blend/feather details in and out is so helpful. I'll definitely be using those tools whenever I work in Z again.
