Hello,
More often Zbrush 2019 will not show any polygroups. Only wireframes will be displayed. What only helps is to save the Ztool,restart Zbrush and reload the file.
Initialize does not work. I can not accurately reproduce the error. It occurs more by accident. Lastly, after running Zremesher 3.0 for the second time with Polyframe on,
but also using ZModeler,switching to Move Brush with Polyframe on.
