I've been trying to find an answer for this on google for ages. I'm still trying to get a hang of zbrush workflow but I find myself working in dynamesh and zremesher more than subdivisions. Is there a way of baking out the normals from a dynameshed subtool onto a subtool that you have decimated, or do you have to use…
It was kinda before that ProBooleans + Inset script in 3ds Max + DynaMesh workflow. Zbrush by itself had Boolean operations for Dynameshed subtools, LiveBooleans kinda based on it.
That's the reason Dynamesh Master is recommended. Instead of guessing the Dynamesh resolution you just type the number of polys you aim for and it will try its best to deliver
If you turn on dynamesh first, you can then subdivide while dynamesh is on. Updating it will automatically clear out any subdivision levels though (it wont ask you to freeze since dynamesh is already on), so I'm not sure if that is what you're looking for. I'm unfamiliar with the tutorial or Raf's workflow.
