Sculpting Head sculpt specifics

One of the best things I got was this real world caliper with a digital read out:

Then if you have the body you are trying to fit, make a measurement front to back/side to side and re-create that shape in 3D (I personally use max/maya for that) then import the correctly scaled mesh into zbrush to reference for size against your head. In the end you will want to boolean a slightly larger sphere from the head so that the two pieces fit together. You can do the same thing with an shook size guide. Just measure the hook side to side/top to bottom and make a simple box in that scale, import to zbrush and use as a reference for how big to make the hole.

My only other bit of advice is to make sure the neckhole and the hole in the head are centered correctly so the head sits just where you want on the neck. (I accidentally printed a head with the connection too far back, and now I need to correct with apoxie and drilling oof!)

OH! one more thing! There is a plugin tool called "caliper master" for zbrush that can help get some real world scale in there, and help you measure things to fit. I'd say getting things to look to scale is the biggest downside of digitally sculpting a head, since it's so much easier in the real world, but we trade it all for that sweet sweet symmetrical sculpting XD
