Finalized the modeling & sculpting on the respirator after client feedback. It turned out to be more challenging than I originally thought due to the double-sided thin geometry. All detailing done within ZBrush 2018. For the cloth pattern, I used a custom alpha created in PS then brought it into ZBrush's MaskByNoise feature within NoiseMaker. Easy peasy! 😁
Next up, baking and texturing.
