What is the proper way to add "content" on a previous subtool? - ZBrush
Hi, I got a skull, and want to add muscles to form a face. I've tried douplicating the skull and using brushes standard, clay, claybuildup and claytubes, but the problem is that this way only deformates previous content, and a skull is very thin and has much holes so this way generates weird results. Should I directly adapt a raw and solid sphere to the skull by move brush, or there is a standard way to do what Im trying?
Thank you.

Not really sure what you want to do, but you can fix the holes in the skull by going to geometry/modify topology/fill holes. I don't know why you need the skull and muscle sculpt in the same subtool, but you can isolate it by giving it a polygroup, hiding everything else in the subtool and then masking it.
Another issue you seem to be running into is that because the mesh is so thin you're simultaneously sculpting the back faces. You can remedy that by turning on "BackfaceMasking."
You may also want to do a global inflate through the deformation tab or use the inflate brush on those super thin areas.
if you want to realistically build up muscle you could try using a tube-shaped Insert curve brush with a size modifier turned on. This will let you add muscle shapes pretty quickly.
