Best method for sculpting thin surfaces?

[system]

Hi guys! I’m working on modeling some popcorn kernels and was wondering if anyone had some tips or techniques for modeling the inside parts of the kernels. I’ve tried extruding a masked area from the main model and that works to get a rough shape but it isn’t good at preserving details. I can export those rough shapes into Maya and edit them into a more detailed version but it is very time consuming. Is there any way to work with thin geometry and precise cut in areas in zbrush? Thanks!

Might be due to the mesh having too low a density to start with. Subdivide a time or two and try again

Thanks Doug, I’ll try it again, I think that will probably work. : )
