The following workflows will take you through how I design a mold using ZBrush and its Draw Draft Analysis tool.
There are also a workflows for remeshing, for creating embossed parting lines as guides for manual blocking in clay, for an analogous process in Blender (not as easy, but much more free), and various mold design, production, and casting tips.
Honey Plushie Pattern
This pattern is free for your use (note that I am not familiar with sewing pattern conventions, but I hope everything makes sense nonetheless).
All I ask is, one, please share your results with me (on Instagram or TikTok) and, two, if you come up with a better version, let me know how you did it!
(And of course please don’t sell them).
