well when i a preview and use inflat tool with zadd enable. instead of inflating the, it’s deflating, and i need to go to negative number on projection to fix the problem, is there anyway i can flip all the normal in different subdivision 
are you sculpting on a Zsphere mesh?
hmm…have fun with that, anyway
once you make an adaptive skin go to
tool>geometry>lowest SubD
tool>display properties>flip
i’m not sculpting in zsphere mode
and when i go to level one and flip it. it will go to my highest subd and flip the normals and delete all the lower levels
. 
then reconstruct the lower ones.
tool>geometry>reconstruct lower
