Dynamesh can be use to re-mesh your head to support the areas you have already sculpted on like your eyelid. [ame="http://www.youtube.com/watch?v=OPVVPa-zsjo"]Zbrush 4R2 Dynamesh 1 The Basics.mp4 - YouTube[/ame]
Regarding subdividing. Lay off of it until your low resolution mesh has all the forms you desier and need. Too many people early on thinkg subdividing willy nilly is amazing and awesome, until they realize they need to make big changes, so everything gets screwed up. Make sure you nail ALL your big forms before you commit…
Wow, yeah that is just what I needed. Thanks! Not much change here, but I found now I have way to many subdivisions making it difficult to smooth out some areas such as behind the ear. Is the only fix to this to use dynamesh earlier in the sculpting process/at a lower res and sculpt in the details again?
