trying to project zsketch sphere volume in to unified skin mesh but seems to not be working in zbrush despite whatever settings i use or adjust, but yet this worked fine in zbrush3.5 r3… can i get any confirmation on this that this feature is broken or is a new bug because it would be cool if this would work in zbrush 4… judging by all the bugs im guesing theres going to be in r1 release some time soon… 
im bumping this again because there wasnt response yet on this issue…
To be honest I’m not sure what you are trying to do. If you are ZSketching then pressing ‘A’ will give you a mesh preview which will very closely match the ZSketch. You can adjust this if you want through the Tool>Unified Skin menu before creating a unified skin.
If this doesn’t answer your question please post images to show what you’re trying to do.
