Model hard surfaces quickly in ZBrush with Extract
Learn a quick hard surface workflow in ZBrush for creating an exosuit and for sculpting around an organic model
This tutorial is by the amazing Andrea Chiampo, freelance concept designer.
Step 01 – The basic steps
Let’s start masking the organic base (in this case a sphere). Once you have the mask, use the extract tool, choosing the appropriate thickness. Now use DynaMesh for having a balanced topology. Now use the ClayPolish Tool for obtaining polished edges and then use Smooth for having them slightly rounded. Use a curve IMM brush.
Step 02 – How to sculpt neat details
Dam_Standard is perfect for having customised lines around the model and ClayPolish is helpful for obtaining neat divisions. At this point create a hole for fitting the strap. Now feel free to use several Alphas for detailing the main piece (I usually prefer to stay minimal, simulating a functional design).
Step 03 – Subtools and materials
Let’s experiment with more Alphas for detailing the whole piece. Once you have circular holes, insert screws using IMM brushes. Now split and group them in different subtools in order to better manage the parts. I suggest you to change the color/material for a better visualization.
Step 04 – Same process, more complex design
This workflow is very handy for creating complex designs. In this case I started from a human character and I used several masks for extracting different pieces ( I also used different thickness). Once you have them extracted I used brushes like Move, Pinch, HPolish, etc… Insertmesh brushes are perfect for adding joints and accessories
